Commons registration and village green rights are some of the most powerful (and often most surprising) constraints a buyer can encounter. They can restrict development, dictate long‑established public access, and even prevent routine changes to land use.
Yet many clients only hear about them for the first time during conveyancing. This short guide explains what commons and village greens are, how they’re recorded, and why they matter for property transactions of all kinds.
What Are Common Land and Village Greens?
Common land refers to land over which certain people – historically “commoners” – hold traditional rights, such as grazing or collecting wood. Village greens are areas traditionally used by local communities for recreation, sports, dog walking or community events. Both types of land are legally protected and cannot be developed or enclosed without specific statutory processes. Even where the land looks unremarkable on the ground, registration as common land or as a village green has a powerful legal effect that can override private ownership ambitions.
How Are They Registered?
Since the 1960s, local authorities have kept statutory registers of common land and town or village greens. These registers record the exact boundary of the land, ownership details (where known), and any rights that exist over it. Registration provides certainty: once land is registered, those public rights are exceptionally difficult to remove. Importantly, registration doesn’t always mean the land is large or well‑known – small pockets, verges, and strips of seemingly unused land can all be listed, and these are often the ones that catch buyers unaware.
Why Does This Matter in Conveyancing?
Registration can have major implications for current and future use. A buyer cannot simply fence off, build on, change or resurface registered land. Stopping up rights of access is extremely difficult. Where a property includes – or abuts – a piece of registered common or village green, that status can have a direct impact on garden extensions, driveways, parking, landscaping, access improvements and development value. Even where the registered land is not being purchased, if it lies adjacent to the boundary, it can limit what the buyer may do and may affect saleability later.
How Do These Appear in Searches?
Local Authority Searches can reveal whether the land being purchased is registered as common land or a village green. However, the search result may only show entries for the land itself, not neighbouring land. This means buyers may still be affected by rights over nearby land even if the register doesn’t flag a direct charge. Planning history can also hint at these issues, especially where previous applications have been refused or restricted due to community use, public access, or longstanding recreational rights. Conveyancers should pay particular attention to boundary plans and any areas used informally by local residents.
What Risks Should Buyers Be Aware Of?
Buyers may unintentionally assume they can improve access, add parking, extend into a side garden, or incorporate an adjoining strip into their title, only to later discover the land is protected. Owners who obstruct or interfere with common land or village green rights may face enforcement action, criminal penalties, or civil challenges. Even if a buyer has no immediate development plans, the presence of registered land nearby can influence valuation, lender comfort and future marketability. It’s also worth noting that local communities can apply to register new village greens, sometimes triggered when land is threatened by development.
Can Registration Be Removed or Changed?
In practice, deregistering land or removing village green status is extremely difficult. There are narrow statutory procedures, but they usually require offering replacement land or proving that the land was wrongly registered. For most homeowners and small developers, these routes are neither simple nor quick. This is why early identification is crucial: buyers need to know how the land is designated before they rely on being able to alter it.
Commons registration and village green rights are powerful legal protections that can significantly influence what a buyer can do with land now and in the future. They can appear in unexpected places and come with consequences that aren’t always obvious at first glance.
By checking the registers early, reviewing boundary detail carefully, and helping clients understand the limits these designations impose, conveyancers can prevent misunderstandings and ensure plans remain realistic from day one.
Ground instability is a quiet but important concern in conveyancing, especially in areas with historic mining, chalk or limestone geology, old quarries, or complex underground infrastructure.
While full sinkholes are rare, the underlying risks – from subsidence to unexpected voids – can affect property condition, insurability and even mortgageability. This quick blog helps conveyancers explain what ground instability means, how it relates to sinkhole formation, and what clients should be aware of when making informed decisions.
What Is Ground Instability?
Ground instability refers to movement, weakening or collapse of the ground beneath a property. It can be caused by natural geological processes, such as dissolution of soluble rocks like chalk or limestone, or by human activity, such as historical mining, tunnelling, quarrying, landfill settlement or old infrastructure failures. Some instability issues progress slowly over time, while others can develop suddenly, which is why environmental searches commonly flag increased risk zones.
How Do Sinkholes Fit Into the Picture?
Sinkholes are one of the most visible (and sometimes alarming) forms of ground instability. They occur when the ground beneath a property collapses into a void, usually created by dissolving limestone, chalk or salt deposits, or by the collapse of an unrecorded mine or man‑made cavity. While dramatic media coverage sometimes gives the impression that sinkholes are common, they remain relatively rare. However, when they do occur, they can cause serious structural damage and require major engineering work.
Where Are Instability Risks More Likely?
Risk often aligns with historic activity or local geology. Former mining areas – coal, chalk, tin, gypsum and other minerals – may contain old shafts, adits or unrecorded workings. Certain regions with limestone or chalk bedrock are naturally more prone to dissolution features. Areas with clay soils may experience shrink‑swell movement during periods of extreme weather. Urban sites built over old landfills or backfilled quarries can experience settlement. Even infrastructure such as leaking drains, broken sewers or failed soakaways can trigger localised collapse beneath driveways or extensions.
How Does This Appear in Searches?
Environmental searches typically assess ground stability risks through national databases, mining records, landfill mapping, historic land use and geological models. They may flag: potential for natural cavities; historic mining activity; known sinkhole incidents; ground that is prone to shrink‑swell clay movement; and areas where subsidence claims have been concentrated. Additional specialist searches from Landmark, such as mining reports, coal authority searches or ground stability assessments, can provide more granular detail. Conveyancers should help clients interpret the difference between a “potential risk” and an “actionable concern”.
What Should Clients Be Aware Of?
Clients should understand that a flagged ground instability risk does not automatically mean the property is unsafe. Instead, it highlights that further checks may be sensible. Clients may need to consider property age, structural history, drainage condition, and whether there have been previous insurance claims for subsidence or movement. Modern homes often incorporate foundations designed for local geology, but older properties may be more vulnerable to underlying ground changes. For planned extensions or significant landscaping, ground conditions may dictate foundation type and cost.
What About Insurance and Mortgage Lenders?
Subsidence and ground instability can influence premiums, excess levels and insurer willingness to cover certain risks. Lenders may ask for more information if a search highlights past instability or historic mining. If a survey or structural report identifies movement, buyers may need to provide additional evidence that the issue is historic, monitored, or already remediated. Promptly addressing insurer or lender queries prevents delays later in the transaction.
Ground instability and sinkhole risk are important but manageable considerations in property transactions. Most flagged risks do not result in dramatic events, but they do warrant thoughtful due diligence.
By helping clients understand the nature of local geology, historic activity and what search results really mean, conveyancers can guide them through practical next steps, whether that’s seeking a structural opinion, engaging with insurers early or simply proceeding with informed confidence.
Biodiversity Net Gain is one of those phrases that feels simultaneously important and slightly mysterious. Luckily, it’s much simpler (and much more logical) than it sounds.
Here’s a friendly, five‑minute guide to help conveyancers explain BNG clearly and confidently, minus the jargon and the drama.
What is Biodiversity Net Gain?
BNG is now a legal requirement for most land developments in England. In short: Every development must leave nature in a measurably better state than it was before.
That means developers need to increase the biodiversity value of a site by at least 10%, using a recognised metric to show that habitats have been created, enhanced, or restored.
This shift reflects a very practical reality: biodiversity has been declining fast. BNG aims to reverse that trend by embedding environmental improvement into the planning system rather than treating it as an optional extra.
How is BNG measured?
This is where the metric comes in – most notably Defra’s Biodiversity Metric 4.0, the industry’s standard tool for assessing habitat value.
Ecologists (or other suitably qualified professionals) assess:
- the type of habitats on the site
- their condition
- their distinctiveness
- their size
- any linear features such as hedgerows or rivers
Each habitat gets a biodiversity “score,” forming the baseline. Developers then show how they’ll deliver at least a 10% improvement on that score.
In practice, this often requires a site visit, and yes, habitat surveys mostly happen in spring and summer, which adds a fun seasonal constraint to planning teams.
How can developers achieve Biodiversity Net Gain?
There are three main routes:
1. On-site improvements
Enhancing or creating habitats within the development boundary — for example, restoring grasslands, adding woodland areas, or improving connectivity between ecological features.
2. Off-site units
When on-site uplift isn’t possible, developers can deliver improvements elsewhere, sometimes using habitat banks: areas of pre-created, high-value habitat that generate biodiversity units.
3. Statutory biodiversity credits
A last resort, used when neither on-site nor off-site options are feasible. These are government-issued credits, designed to fill unavoidable gaps rather than be a go‑to solution.
Most schemes blend the three to meet their uplift target.
Why does Biodiversity Net Gain matter to conveyancers?
Although BNG primarily affects the planning and development stages, it’s becoming increasingly important in transactions too, especially where:
- land is being sold for development
- development sites change hands mid‑process
- off-site biodiversity units are being purchased or traded
- long-term habitat management obligations (often 30 years) are attached to land
Key considerations include:
- Legal agreements, such as Section 106 obligations securing habitat creation and maintenance
- Land charges that bind future owners to ongoing ecological management
- Liability and stewardship, including who is responsible for monitoring and maintaining habitats over the long term
- Valuation, since BNG potential can inflate or depress a site’s development prospects
A little early clarity can prevent big headaches later.
Is BNG good news?
In a word: yes. It ensures development contributes positively to the environment, encourages smarter land use, and helps protect ecosystems that support everything from pollination to flood resilience.
It also aligns with wider sustainability goals and, increasingly, consumer expectations. Nature recovery is no longer a fringe concern – it’s becoming part of mainstream development practice.
Biodiversity Net Gain is a significant, forward‑looking change to how we plan, build, and value land in England. For conveyancers, it’s another dimension of due diligence – but also an opportunity to help clients understand a major shift in environmental responsibility.
And despite its name, BNG isn’t about hugging trees (though no judgement). It’s about ensuring that development leaves nature better off than it found it – with a clear metric, a legal backbone, and practical pathways to deliver meaningful ecological uplift.
As part of the continued roll out of new and remastered reports, our attention has turned to our agricultural offering, the SiteSolutions Farm report.
You might wonder why it’s important to order a SiteSolutions Farm report instead of a traditional environmental search, after all, don’t they cover the same factors? In reality, agricultural transactions involve a host of unique considerations. For example, the Environment Agency has reported that agricultural runoff is the single biggest polluter of rivers, responsible for 40% of waterway damage. This highlights the need for an agricultural report that goes beyond a standard contaminated land liability assessment.
Agricultural considerations
Farm transactions involve a broader range of factors, often making reports more complex and harder to interpret. Our reports are built differently – offering clear analysis and mapping of key agricultural issues such as pollution incidents, poor land management, intensive farming, and land classification, alongside standard assessments of flood and contamination risk. These localised factors, unique to agricultural land, are surfaced and presented as prudent enquiries to help conveyancers identify potential issues early, facilitating a smoother transaction.
Template redesign
The redesigned front page features a clear summary that instantly highlights contamination and flood risks, with direct hyperlinks to the relevant sections within the report. Risk ratings, summary maps, and consultant commentary are now unified on one page, allowing clients to quickly access the same insights as our consultants and build confidence in our conclusions. All data is analysed by a consultant and presented in plain English, free of jargon and acronyms, for clarity and accessibility. Author contact details are also prominently displayed for easy access to expert support.
Professional opinion
At Landmark, we believe that assessments without environmental consultant input fall short. Our reports empower consultants to apply their expertise, rather than simply echoing raw data, which often lacks context. A great example of this is in the flood section, where automated data can exaggerate the nature and extent of risk. Our consultants assess flood risk holistically, considering topography, land type, and existing water features, to provide a more accurate and representative outcomes. Justifications for these assessments are included in the commentary, ensuring transparency. We only report a risk as significant when it truly is.
Considering development?
With the government placing greater emphasis on energy scrutiny and the transition to a low-carbon economy, there’s a growing trend in renewable energy projects. Farm owners are increasingly seeing this as an opportunity to diversify their land, especially in areas that don’t yield strong returns from traditional farming. The good news is that, provided certain parts of the farm remain in agricultural use, the SiteSolutions Farm report can support redevelopment projects such as solar and wind farms.
Summary
Our farm report is tailored to the specific context of agricultural transactions, with bespoke recommendations that highlight potential liabilities and localised risks, from flooding to broader environmental factors unique to farmland. It offers comprehensive oversight for every transaction.

When purchasing a residential property, especially a high-value or complex one, environmental risks are often overlooked until it’s too late. Industry analysis shows that skipping thorough environmental due diligence can lead to costly surprises, legal headaches, and even failed transactions.
Here’s why Landmark’s redesigned Argyll SiteSolutions Residence report could be your smartest investment in peace of mind.
When your clients dream home comes with a hidden legacy
Picture your client purchasing their ideal home, only to later uncover that the land beneath it was once used for industrial purposes, such as a gas works or depot. While not every case makes headlines, this kind of situation is not uncommon. There are numerous examples where homeowners have discovered soil contamination linked to historic land use, triggering a long and complex process to determine who is responsible for the clean-up costs.
One particularly striking case is in Willenhall, where residents endured a decade-long ordeal after discovering their homes were built on a former gas works site that closed in 1957. The properties were developed by McClean and E Fletcher Builders (now dissolved), and in 2007, Walsall Council began investigating the site as part of its contaminated land strategy. They discovered areas contaminated with benzo(a)pyrene, a known carcinogen, alongside heavy metals, tars, and a gasworks by-product called Blue Billy. The contamination posed a significant possibility of harm, and nearly 90 homes near Kemble Close, Oakridge Drive, and Brookthorpe Drive were declared affected.
In 2015, Walsall Council served a remediation notice on Jim 2 Limited, claiming the company was liable for the contamination. The firm appealed to the Planning Inspectorate, leading to a public inquiry. After years of legal wrangling, the local authority was left with a potential £2.5 million remediation bill, and residents were left in limbo, uncertain when or how the remediation would be completed.
Had a SiteSolutions Residence report been commissioned during the purchase process, our environmental consultants would have flagged the site’s industrial history and potential contamination risks through detailed historic land use analysis. This would have empowered buyers to renegotiate, seek further investigation, or walk away before committing.
Flood: the growing threat
Flooding is still too often seen as a concern limited to riverside properties. Today, more than 4.6 million homes across the UK are at risk from surface water flooding, a number that continues to rise.
When selecting an environmental search for a residential property, the SiteSolutions Residence report stands out as the most comprehensive choice. Our consultant-led flood risk assessments take into account the entire site, delivering a more accurate and practical understanding of flood exposure, particularly valuable for larger or more complex properties.
This boundary-based approach helps buyers and conveyancers:
- Identify flood risk across the full extent of the property, including gardens, driveways, and outbuildings.
- Provides advice on how flood risk may affect planned renovations, extensions, or future development.
- Flag potential insurance challenges or premium increases that could impact affordability or mortgage approval.
Understanding future risks
With the release of the Law Society’s Guidance on Climate Change in 2023, followed by the “Climate Change and Property” practice note for solicitors published in May 2025, environmental due diligence is now expected to go beyond present-day risks. As warmer, wetter winters and hotter, drier summers become more common, these shifting weather patterns, along with rising sea levels, are increasing the likelihood of hazards such as flooding, subsidence, coastal erosion, and heat stress.
To help buyers understand how these future scenarios could affect the usability, value, or adaptation needs of a property, our redesigned SiteSolutions Residence report offers the option to include or exclude climate change analysis, at no extra cost. This flexibility allows conveyancers and their clients to tailor the level of insight to suit the needs of each transaction.
This enhanced due diligence helps to:
- Highlight long-term environmental risks that may affect how a property is used or maintained over time.
- Identify areas where adaptation measures are required, such as flood defences or insulation upgrades may be necessary, helping clients plan for future costs.
- Demonstrate a proactive approach to risk management, aligning your advice with best practice and reinforcing your commitment to thorough client care.
By integrating climate change analysis, the SiteSolutions Residence report supports both home buyers and solicitors in navigating an evolving risk landscape, ensuring that your transaction is underpinned by robust, forward-looking due diligence.
Legal liabilities: protecting buyers and solicitors
Lack of environmental due diligence doesn’t just hurt buyers, it can also lead to legal claims against solicitors. Missed risks like contamination or flood zones can result in unexpected remediation costs, mortgage refusals, or even lawsuits. The Law Society recommends comprehensive environmental searches for all property transactions, especially for high-value or older homes. The SiteSolutions Residence report is manually written and reviewed by accredited consultants, providing clear, actionable insights that protect both buyers and legal professionals.
What makes the SiteSolutions Residence report different?
- Manual, consultant-led analysis: every report is written and reviewed by an IEMA-accredited environmental consultant, not just a computer algorithm. This enables enhanced due diligence of environmental risks.
- Bespoke risk assessments: the report evaluates potential contamination risks both on-site and in the surrounding area, helping you understand how historic or nearby contaminative land uses could create legal liabilities or impact future development plans. Our flood risk assessments also highlight any concerns that may affect the current use of the property or any proposed changes, ensuring you and your clients are fully informed before proceeding.
- Boundary-based reporting: the report assesses the actual site boundary, not just a central point, crucial for large or irregular properties.
- Actionable recommendations: bespoke guidance on next steps, so you’re never left guessing.
Don’t let your clients dream home become a nightmare
Whether you’re a buyer, solicitor, or property professional, the Argyll SiteSolutions Residence report is your safeguard against hidden environmental risks. It’s not just about ticking a box, it’s about making informed decisions, protecting your investment, and ensuring peace of mind.

Climate change is no longer a distant threat for the UK property sector, it’s a present-day reality, influencing everything from buyer behaviour to professional advice.
Landmark’s latest cross-market research draws on the perspectives of 150 senior property professionals, including 50 estate agents, 50 residential conveyancers, and 50 mortgage lenders, to reveal how the industry is adapting to this new landscape, where climate risk is now a central part of the conversation.
Climate risk moves to the forefront
Over the past year, concern about climate change has become nearly universal among property buyers and professionals. The sector is seeing this shift first-hand. The days when climate risk was a niche topic are over; it’s now a mainstream consideration that can make or break a transaction.
This heightened awareness is having tangible effects. Conveyancers report that buyers are increasingly willing to walk away from deals if climate risk reports raise red flags. The financial implications are significant, with concerns about mortgage approvals and insurance coverage now tied directly to climate-related findings.
What’s driving this change?
The research points to a shift from general uncertainty about climate change to more practical, property-specific concerns. Energy performance remains a top priority, but more regular heatwaves have pushed heat stress up the agenda. Buyers and professionals alike are asking tougher questions about how homes will cope with rising temperatures, and what features, such as, ventilation, insulation, and EV charging points will help future-proof their investments.
Flooding, once the dominant concern, has slipped down the list, replaced by worries about heat, subsidence, and even coastal erosion. This suggests a more nuanced understanding of climate risk, with buyers looking for homes that are resilient to a wider range of environmental challenges.
Professional advice is evolving
As climate events become more frequent and severe, property professionals are adapting their approach. The majority now recommend further due diligence, such as, climate risk reports earlier in the buying process. There’s also a growing trend towards upfront disclosure, with estate agents increasingly confident in discussing climate risks with clients from the outset.
However, the question of who should take responsibility for advising on climate risk remains open. While environmental specialists are still seen as key, more estate agents and conveyancers are stepping up, supported by new best practice guidelines and internal policies. The Law Society’s recent practice note has provided some clarity, but many professionals are still navigating how to put this guidance into practice.
Barriers and opportunities
Despite this progress, the sector faces real challenges. Uncertainty around regulation and a lack of clear client demand are slowing the pace of change. Data gaps, limited training, and the cost of new tools are also barriers that need to be addressed. Yet, there are signs of optimism: more firms are developing and publishing net zero strategies, and consumer demand for sustainable features is rising fast.
The road ahead
Landmark’s latest research makes it clear that the property sector is at a turning point. Climate risk is now a core part of property decisions, and the industry is responding with greater transparency, better advice, and a stronger focus on resilience. The journey isn’t over, there’s still work to do to embed best practice, clarify responsibilities, and support buyers in making informed, future-ready choices.
But as extreme weather becomes the new normal, one thing is certain: the property sector can’t afford to stand still. Those who adapt will be best placed to thrive in a climate-conscious market.
