Flood risk is one of the most important environmental considerations in any property transaction. It affects insurance, mortgageability, future development, and sometimes the long‑term comfort of simply living in the home.

Yet many clients only think about flooding in terms of rivers bursting their banks, when the real picture is far broader and more nuanced. This short guide explains the different types of flood risk, how they appear in searches, and what buyers should be thinking about before committing to a purchase.

What Do We Mean by Flood Risk?

Flood risk describes the likelihood of water affecting a property from a variety of sources. River and coastal flooding are the most well‑known, but surface water flooding, groundwater flooding, overloaded drains, failing infrastructure and even blocked culverts can all pose significant hazards. Modern environmental searches draw from national mapping, historic incidents and modelling to assess the level of risk for a specific location, but risk varies over time based on weather, land use and climate patterns.

Types of Flooding Clients Should Understand

There are several categories buyers should be aware of.

  • River flooding occurs when rivers overflow their banks after heavy or prolonged rainfall.
  • Coastal flooding occurs in low‑lying coastal areas during storms or high tides.
  • Surface water flooding happens when rain cannot drain away quickly enough, often following intense downpours.
  • Groundwater flooding arises where water tables rise and seep into basements or low‑lying land.
  • Sewer flooding happens when drainage systems are overwhelmed or blocked.

Each behaves differently, appears in different map layers and may have different implications for insurance and property use.

How Does Flood Risk Appear in Searches?

Environmental searches typically highlight: flood zone classifications; surface water risk mapping; historic flood events; proximity to rivers, coastlines or flood defences; risk from reservoirs or canals; groundwater susceptibility; sewer flooding history; and whether the site is subject to flood alerts or warnings. Planning records may also contain flood‑related conditions, such as requirements for flood‑resilient construction, finishes, or safe access and escape routes. Together, these elements help conveyancers interpret whether the risk is theoretical, low‑level, or something that warrants further investigation.

What Should Buyers Be Aware Of?

Clients should understand that “flood zone” does not always equate to insurance difficulty — some high‑zone areas have excellent defences, while some low‑zone areas flood because of poor surface water drainage. Insurance is often the most practical lens: can the buyer obtain cover at a reasonable cost and on standard terms? Lenders may also want reassurance that insurance is available. Buyers planning extensions or significant alterations should note that high‑risk areas may require a Flood Risk Assessment as part of a planning application, and may face stricter design and mitigation requirements.

What About New‑Build Developments?

New‑build homes in flood‑prone areas often include engineering measures such as raised floor levels, flood‑resilient materials, sustainable drainage systems (SuDS) and attenuation features designed to slow or store rainwater. While these are generally positive, they sometimes come with management charges or long‑term maintenance requirements. Buyers should understand the purpose of any on‑site ponds, tanks or swales, who maintains them, and whether they impose any restrictions on landscaping or construction.

How Should Conveyancers Advise on Flood Risk?

The best approach is to take search results seriously but calmly. Many flagged risks simply warrant extra checks or insurance confirmations rather than derailing the transaction. Conveyancers should recommend that clients: review insurance availability early; consider a specialist flood risk report if search results indicate medium or high risk; understand the history of the property, including any known flood incidents; and, where relevant, obtain clarity from the seller about any mitigation measures already in place. Clients should also know that flood risk can affect resale value and buyer perception.

Flood risk is complex, but manageable with the right guidance. By explaining the different types of flooding, helping clients interpret search results, and encouraging early insurance checks, conveyancers can give buyers confidence and clarity.

In many cases, the presence of flood risk is a sign to gather more information – not a reason to walk away. What matters most is understanding the level of risk, how it affects the property, and what steps can be taken to minimise it now and in the future.

Completion Notices are one of those planning tools that rarely appear in everyday conversation but can have a real impact on buyers, developers and anyone relying on an existing planning permission.

They’re often misunderstood, especially because the name sounds similar to completion certificates – but they are entirely different things. Here’s a quick, clear guide for clients and conveyancers on what Completion Notices are, when they’re used and why they matter in a property transaction.

What Is a Completion Notice?

A Completion Notice is issued by a local planning authority when it believes that development which has started will not be completed within a reasonable period.

The effect of the notice is to set a deadline: if the development is not finished by the date given, the planning permission will be treated as having expired for any incomplete work. In other words, the permission is “switched off” for the unfinished parts of the project. A Completion Notice does not force anyone to finish the work, it simply removes the protection of the existing planning permission after a specified date.

When Are Completion Notices Used?

Completion Notices are typically used where a planning permission has technically been implemented, but then left unfinished for months or years. Sometimes this is because the developer mothballs the project; sometimes because the property has changed hands; sometimes because the market has shifted.

Councils can issue a Completion Notice when they believe the planning permission is being kept alive without real intent to complete. It is not a punitive measure – it is a tidying-up mechanism to prevent open‑ended permissions remaining valid indefinitely.

What Does a Completion Notice Do?

The notice sets out a completion date, usually at least 12 months from the date it is served. If the work is finished by that deadline, the permission remains lawful. If not, any incomplete elements lose the benefit of that permission and future works would require a fresh application. Importantly, a Completion Notice does not affect work already lawfully completed – only the unfinished parts are at risk. This distinction matters for buyers inheriting part‑built extensions, conversions, shopfront works or redevelopment schemes.

How Do Completion Notices Affect Conveyancing?

If a property involves unfinished works or has an historic planning permission that was only partially implemented, a Completion Notice can materially affect value, development potential and mortgageability. Buyers may assume they can pick up where the previous owner left off… but a Completion Notice may limit what can still be lawfully completed without a new permission.

Lenders may also ask questions if a planning permission is close to expiry or if the remaining works are substantial. For developers purchasing stalled sites, understanding whether a Completion Notice has been issued, or could realistically be issued, is essential due diligence.

Will Completion Notices Show Up in Searches?

Completion Notices can appear in Local Authority searches when formally served, but they are not as common as enforcement notices. Sometimes the only evidence is in the planning history, which may reference a pending notice, consultation on a proposed notice or an intention to issue one. Because the effect of a Completion Notice is tied to the status of an existing planning permission, conveyancers should always check the planning timeline: When was the permission granted? Was it materially started? How much work was done? Does the council appear to consider the permission dormant?

What Should Buyers and Developers Look Out For?

Clients should be aware of any part‑built structures, groundworks or foundations that were installed solely to “keep a permission alive”. They should also understand that finishing the work may still require compliance with updated building regulations or new planning policies, even if the original permission is technically still in play. Where a Completion Notice has been served, buyers need to know the cut‑off date and whether the remaining works are realistically achievable within the timeframe. Where no notice has yet been served, but the project has been dormant for years, it’s sensible to advise that the council could tighten the timeline.

Completion Notices are a planning tool designed to bring clarity to long‑stalled developments. They don’t punish owners, and they don’t invalidate completed work – but they do remove the safety net of an old planning permission if the project isn’t finished by a specified date.

For conveyancers, the key is to spot early when a transaction involves part‑completed development, long‑dated permissions or dormant projects. A simple review of planning history and a discussion with the client can prevent surprises later and ensure they know exactly what they can – and cannot – lawfully complete after purchase.

When clients think about buying or improving a property, advertising is rarely the first thing on their mind, but for shopfronts, small businesses, and mixed‑use premises, Advertisement Control can influence what they can display, where they can display it, and whether consent is required at all.

This short guide breaks down the essentials your clients need to know, and what you should look for during conveyancing.

What Is Advertisement Control?

In England, the display of outdoor advertisements is governed by a standalone consent regime within the planning system. It sits separately from standard planning permission and is primarily concerned with two things: amenity and public safety.

The rules flow from the Town and Country Planning (Control of Advertisements) (England) Regulations 2007, which set out what constitutes an “advertisement” and how consent is obtained. Under the statutory definition, an advertisement includes “any word, letter, model, sign, placard, board, notice, awning, blind, device or representation… whether illuminated or not” that’s used to advertise, announce, or direct.

In other words: if it communicates something visually for commercial or directional purposes, it’s probably an advert.

How Are Advertisements Controlled?

There are three categories of control:

1. Advertisements permitted without consent

Certain adverts are exempt under Schedule 1 of the Regulations, provided they meet standard conditions (clean, safe, owner’s permission, etc.).

2. Advertisements with deemed consent

Some types – including many shopfront signs, temporary notices and certain flags – benefit from deemed consent if they meet the stated criteria.

3. Advertisements requiring express consent

If the advert doesn’t fall into the first two categories, the owner must apply to the local planning authority for express consent. Decisions focus solely on visual amenity and public safety, not commercial content.

This lighter‑touch approach often surprises clients who assume they need full planning permission, when in reality the test is narrower and more specific.

Areas of Special Control of Advertisements

Some rural, scenic, and environmentally sensitive areas are designated as Areas of Special Control, where restrictions are tighter. These locations place more limits on advert size, height, illumination and format. ASCAs aim to protect landscape character by curbing visual clutter.

If your client is buying in or near a National Park, the Broads, or certain urban development areas, expect advertisement control to be stricter.

How Does This Show Up in Searches?

Land Charges within Regulated Search reports such as OneSearch Prime may reveal:

  • Existing Advertisement Control Orders affecting the property
  • Enforcement actions relating to unauthorised signage
  • ASCAs covering the wider area
  • Conditions attached to planning permissions limiting signage size, lighting or placement

Many enforcement cases relate to shopfronts, A‑boards, illuminated signs, and large fascia changes installed without consent.

Why It Matters for Your Clients

Small businesses, retail units, cafés, takeaways, salons and offices frequently plan new signage after completion. Advertisement control affects:

  • Signage design and size
  • Illumination and digital screens
  • Projecting signs and fascia boards
  • Temporary banners or promotional displays
  • Flagpoles and branding (recently clarified and more flexible under flag‑related amendments to the Regulations)

A quick upfront explanation of what is and isn’t allowed can prevent disappointment later.

What Should Conveyancers Flag Early?

Here’s a simple checklist for clients buying or leasing a property:

  • Is the property in an ASCA?
  • Are existing signs lawful? (especially if illuminated or projecting)
  • Has any enforcement action been taken or threatened?
  • Does the client intend to rebrand, add illumination, or install digital screens?
  • Do any old planning conditions restrict signage?
  • Is express consent likely to be needed?

If uncertainty remains, signpost clients to the local planning authority’s guidance or the national GOV.UK advertisement guidance.

Advertisement Control is a focused but important part of planning that often sits below a buyer’s radar until it becomes a problem – usually when signage has already been ordered or installed. With a few quick checks during the transaction, conveyancers can help clients understand what’s allowed, what requires consent, and how local controls may shape their plans.

Subsidence and mining aren’t exactly the glamorous side of property (unless you’re particularly fond of soil classifications), but they’re hugely important for understanding how safe, stable and mortgage‑friendly a home really is.

For conveyancers, agents and lenders, these risks sit quietly beneath the surface – sometimes literally – waiting to be discovered during due diligence.

For buyers, too, they matter more than most realise. After all, nobody wants to move into their dream home only to learn it’s doing a gradual impersonation of the Leaning Tower of Pisa.

What Do We Mean by Subsidence?

Subsidence is the downward movement of the ground beneath a building, causing the structure to shift or crack. It can be triggered by:

Shrink‑swell clay soils

These expand in winter, contract in summer, and generally behave like a moody teenager – unpredictable and occasionally dramatic.

Tree roots

Large trees can draw moisture from the soil, causing it to contract. Lovely to look at, less lovely when your bay window starts to twist.

Drainage or leaks

Escaping water can wash away fine materials in the soil, undermining foundations.

Historic development or ground disturbance

Old landfills, made‑up ground or former industrial plots can behave inconsistently over time.

While many causes are harmless or easily managed, some require early attention to avoid major repair bills later.

Where Does Mining Risk Come In?

Mining activity, especially historic coal, tin, ironstone or chalk works, can leave behind voids, shafts, tunnels or weakened ground. These aren’t always obvious on the surface, but they can affect stability long after the last miner clocked out.

Mining risks can include:

  • Old mine workings
  • Collapsible ground
  • Unrecorded shafts
  • Opencast sites
  • Ground gas issues in former mineral areas

Properties in historic mining regions often require a specialist mining report, which is as thrilling as it sounds but very important.

Why Subsidence & Mining Matter in Conveyancing

Both issues influence safety, long‑term maintenance, mortgageability and insurance. Lenders want reassurance that the property isn’t at unusual risk, insurers want to price the risk accurately, and buyers want walls that don’t crack every time it rains.

Common red flags include:

  • Reports of past subsidence
  • Claims history
  • Local geology indicators
  • Known mine workings
  • Previous stabilisation works
  • Structural movement noted in surveys

Explaining these clearly to clients builds trust and helps them understand whether the risk is low, manageable or something that needs deeper investigation.

How Buyers Can Protect Themselves

Fortunately, most subsidence and mining risks can be understood early through:

  • Environmental and mining searches
  • Building surveys
  • Engineer evaluations where needed
  • Local authority knowledge
  • Specialist Coal Authority reports
  • Checking insurance history
  • Talking to neighbours (always more fun than it sounds)

Early clarity helps avoid renegotiations, insurance surprises or unwelcome discoveries after completion.

Subsidence and mining might not be the most exciting topics at a viewing, but they’re among the most important. These issues don’t have to be deal‑breakers; in fact, most are perfectly manageable when spotted early. The real value comes from taking a calm, methodical look at the property’s history and the ground beneath it.

Think of subsidence and mining risks as the quiet characters in the background of the transaction: not showy, not dramatic, but incredibly influential. Spot them early, explain them clearly, and your clients will feel far more grounded… in every sense.

Assets of Community Value are one of those charming quirks of the planning world: part community empowerment, part legal mechanism, part “please don’t bulldoze our favourite pub.”

They’re small in scope, but big in spirit – and they matter more than most buyers realise.

For conveyancers and agents, a solid understanding of ACVs helps explain why certain listings appear in searches, why some sales take longer than expected, and why that quiet village hall suddenly has surprising legal importance.

What Is an Asset of Community Value?

An Asset of Community Value is a building or piece of land that local people believe significantly benefits community life. Think village greens, football pitches, community centres, the classic “last remaining pub,” or even a much‑loved café that hosts half the town’s clubs and classes.

Local groups can nominate a property to be listed by the council. If accepted, the property is officially placed on the ACV register for five years. During that time, any intention to sell triggers special rights for the community.

So yes, sometimes the locals really can put a pause on the big developer’s plans… at least for a little while.

Why Do ACVs Matter in Property Transactions?

When a property is listed as an ACV, it appears on the Local Land Charges Register. That means conveyancers instantly pick it up in searches. The ACV status doesn’t stop a sale, but it can add steps:

  • The owner must notify the council before selling.
  • A 6‑week interim moratorium begins.
  • If a community group expresses interest, a 6‑month full moratorium kicks in.
  • During that period, the property cannot be sold to anyone else.

The owner isn’t required to accept a community bid, but the moratorium still applies. It’s a pause button, not a veto.

How Long Do ACVs Last?

ACV listings last five years, after which they expire unless the community reapplies. Once expired, the entry should be removed from the register – this is why it’s important to check whether the status is current rather than simply lingering on paperwork.

Who Should Care About ACVs?

Everyone involved in the transaction… but especially buyers.

ACVs can affect:

  • Timescales (thanks to moratorium periods)
  • Development potential (although not directly restrictive, they signal local interest)
  • Public perception (no one wants to be “that person” who closed the community’s favourite asset)
  • Long‑term plans for the site

If a client wants to renovate, redevelop or repurpose a building, an ACV listing is a hint that local opinion might be… enthusiastic.

ACVs are one of those little flags that pop up in searches and make everyone lean in a bit closer. They’re not there to derail transactions, but they do tell a story about how much the community values a place… and that story matters. Taking a moment to explain what an ACV is, how long it lasts, and what it means in practice can calm nerves before they even start to fray.

Handled early, ACVs become a well‑managed part of the journey rather than an unexpected speed bump. Think of them as the neighbourhood raising a polite hand to say, “We care about this one.” A quick explanation, a check of the dates, and a little clarity go a long way – turning what looks like a complication into a simple, human part of the conveyancing process.

Traffic schemes may not sound glamorous (unless you’re the sort of person who gets excited by bollard spacing), but they play a huge role in shaping neighbourhoods.

… and, by extension, the experience of living, working or investing in a property. For conveyancers and agents, they’re one of those deceptively important background factors that can influence everything from parking to noise to accessibility.

What Are Traffic Schemes?

A traffic scheme is any planned change to the way people and vehicles move around an area. Councils introduce them to improve safety, manage congestion, support public transport, encourage active travel or simply bring a bit of order to a street where chaos has become a daily sport.

Most traffic schemes are powered by a Traffic Regulation Order – the formal legal tool that turns “please don’t park here” into “definitely don’t park here unless you enjoy unexpected fines.”

The Common Types of Traffic Schemes

Traffic schemes come in many forms, and you’ve probably encountered most of them without realising they had official names.

Common examples include:

  • Traffic calming

Speed humps, raised tables, and chicanes designed to slow down drivers. These measures aim to protect vulnerable road users and encourage safer speeds.

  • Controlled Parking Zones (CPZs)

Areas where on‑street parking requires a permit.

  • Weight and width restrictions

Designed to stop heavy lorries from thundering down residential streets better suited to pushchairs and wheelie bins.

  • One‑way systems and turn bans

Helpful for reducing collisions, though occasionally guilty of confusing anyone who relies on instinct rather than signposts.

  • Pedestrianisation and public realm changes

Turning streets into people‑first spaces with fewer cars, better air quality, and (if the council is feeling fancy) planters. However, people forget that traders need access to Dixons…

  • Cycle tracks and bus lanes

Infrastructure that supports greener transport and, more importantly, offers cyclists a safe space to pedal.

Why Traffic Schemes Matter in Conveyancing

For homeowners and businesses, traffic schemes influence accessibility, parking, noise levels, commuting patterns, delivery routes, and general convenience. That means they can subtly influence desirability, value, and even lifestyle.

For professionals, they matter because proposed or existing schemes often appear in CON29 enquiries. Buyers want to know whether a road is about to become one‑way, whether parking is being restricted, or whether an upcoming scheme might affect access during construction.

Traffic schemes may look like tiny adjustments to a map, but they can have a remarkably big impact on daily routines, from school runs to supermarket dashes. That’s why taking a moment to understand them during conveyancing is such a good investment. It gives your clients confidence, clears up assumptions before they cause trouble, and helps everyone know what to expect. Think of traffic schemes as the subtle foreshadowing of neighbourhood life: they hint at how a place is evolving. Spot them early, explain them clearly, and they become part of the story rather than a surprise plot twist halfway through the transaction.
