Before You List in South West England

The South West is one of England's most distinctive property markets. With around 74,000 sales per year and an average price of roughly £320,000, the region stretches from Bristol and Bath through Somerset, Dorset, Devon, and down to the tip of Cornwall. Each county brings its own quirks to the conveyancing process.

Unlike the South East and most of England, the South West's mining heritage is tin and china clay rather than coal. It has England's highest radon levels, a substantial holiday-home market with capital gains tax implications, a concentration of thatched cottages with specialist insurance needs, and significant coastal erosion risk along parts of the Devon, Cornwall, and Dorset coastline. This guide covers everything you need to prepare before listing your South West property for sale.

South West England market snapshot

Here is a summary of the current South West property market at a glance. These figures should help you set realistic expectations around pricing, timescales, and buyer demographics.

The South West has one of the lowest leasehold rates in England, meaning most transactions involve freehold properties. However, the region's older housing stock and rural character mean that title deeds can be more complex, particularly for properties that predate the Land Registry's compulsory registration requirements.

What makes selling in the South West different

Every region in England has its own conveyancing peculiarities, but the South West stands out in several ways. Understanding these before you list will help you anticipate buyer enquiries and avoid delays once you accept an offer.

Non-coal mining: tin and china clay

While regions like Yorkshire and the North East deal with coal mining searches (the standard CON29M form), Cornwall and parts of Devon have an entirely different mining heritage. The region was once one of the world's largest producers of tin, copper, and china clay. This means properties in former mining areas require a non-coal mining search instead of — or sometimes in addition to — the standard coal mining search. The non-coal mining search checks for old mine shafts, adits (horizontal mine entrances), stopes, and other underground workings that could affect ground stability. If your property sits on or near former mining land, having this search ready before you accept an offer can save valuable time. You can read more about the different types of property searches explained in our guide.

England's highest radon levels

Radon is a naturally occurring radioactive gas that seeps from granite and certain other rock types. The South West — particularly Devon, Cornwall, and parts of Somerset — has the highest radon concentrations in England. Public Health England designates radon-affected areas on its radon atlas, and buyer's solicitors will routinely request a radon report for properties in these zones. If your home is in an affected area, you should consider obtaining a radon certificate before listing. If levels exceed the action level of 200 Bq/m³, buyers may ask what mitigation measures are in place, such as a radon sump, positive ventilation system, or radon-proof membrane. Disclosing known radon levels and any remediation on the TA6 property information form is good practice and helps build buyer confidence.

Holiday homes and capital gains tax

The South West has one of the highest proportions of second homes and holiday lets in England, particularly in coastal Cornwall, North Devon, the Jurassic Coast, and the Cotswolds fringe. If the property you are selling is not your principal private residence, you will be liable for Capital Gains Tax on any gain. CGT rates for residential property disposals are 18% for basic-rate taxpayers and 24% for higher-rate taxpayers. You must report and pay within 60 days of completion using HMRC's online CGT service. It is essential to confirm your CGT position before listing so you can price the property correctly and avoid surprises at completion. Additionally, if the buyer is purchasing the property as a second home or buy-to-let, they will face a 5% stamp duty surcharge on top of standard rates, which may affect what they are prepared to offer.

Thatched cottages

Thatched cottages — a South West speciality — have unique insurance, maintenance, and disclosure requirements. We cover these in detail in the property types section below.

Coastal erosion

North Devon, the Cornwall coast, and the Dorset Jurassic Coast are all subject to varying degrees of coastal erosion. The Environment Agency publishes Shoreline Management Plans that categorise stretches of coastline into four policy options: hold the line, advance the line, managed realignment, and no active intervention. Properties in 'no active intervention' zones face the most scrutiny from buyer's solicitors. Insurance limitations can be significant — the Flood Re scheme covers flood risk but not erosion risk. If your property is close to a cliff edge or eroding coastline, you should check the relevant Shoreline Management Plan and consider obtaining an Environment Agency assessment before listing. Transparency about coastal risk in your TA6 form will help avoid abortive sales later in the process.

Property searches in the South West

Your buyer's solicitor will order searches as part of the conveyancing process. Knowing which searches apply to your property — and how much they cost — helps you anticipate delays and prepare accordingly. For a full overview of how searches work, see our guide on property searches explained.

The non-coal mining search is the one that catches many sellers and agents off guard in the South West. If you are selling in Cornwall or parts of Devon, ask your solicitor whether this search is likely to be required. Having it ready in advance can prevent a 2–5 day delay once your buyer's solicitor requests it.

Local authority search turnaround times

The local authority search is typically the slowest part of the search pack. Turnaround times vary considerably across South West councils. Knowing your council's typical turnaround helps you plan your timeline and set buyer expectations. Understanding how long conveyancing takes overall will also help you plan ahead.

Cornwall, Dorset, and Wiltshire tend to have the longest waits, often due to high transaction volumes relative to staffing levels. If you are selling in one of these areas, consider instructing your solicitor early so the local authority search can be submitted as soon as possible. Some councils offer expedited services for an additional fee — check directly with your local authority.

South West property types and their quirks

The South West has a diverse housing stock that ranges from Georgian terraces in Bath to remote farmhouses in Exmoor. Several property types in the region come with specific considerations that you should address before listing.

Thatched cottages

Devon, Dorset, and Somerset are home to thousands of thatched properties. Selling one requires careful preparation — see our dedicated guide on selling a thatched cottage for a full walkthrough. Key disclosure points include the date and scope of the last re-thatch (typically needed every 25–40 years depending on material), the type of thatch used, and fire risk measures such as spark arrestors or fire retardant treatments. Listed building status adds another layer, as any alterations — including switching thatch materials — may require listed building consent. Specialist insurance is more expensive than standard home insurance, and buyers will expect to see evidence of a current policy with adequate cover. Having a thatch condition report from a qualified thatcher can reassure buyers and prevent renegotiation after the survey.

Coastal properties

Properties on or near the coast face scrutiny around erosion risk, flood risk, and insurance availability. If your property is on a flood plain, our guide on selling a house on a flood plain covers what to expect. The Environment Agency's coastal erosion risk maps show projected shoreline positions over 20, 50, and 100 years. If your property falls within a projected erosion zone, this will be flagged during searches. The Flood Re scheme (available for properties built before 2009) makes flood insurance more affordable but does not cover erosion. Properties in high-risk coastal zones may need specialist insurance, and some mortgage lenders will not lend at all on properties at immediate risk. Check your position with the Environment Agency and your insurer before marketing.

Former mining properties

Cornwall's tin mining heritage is part of a UNESCO World Heritage Site, but it also means many properties sit on or near former mine workings. Key concerns include proximity to mine shafts, subsidence history, and ground stability. A non-coal mining search will reveal whether known workings affect the property. If the search identifies nearby shafts or adits, the buyer's surveyor may recommend a ground stability report. Properties with a clean mining search result can proceed smoothly, so having this ready in advance is particularly valuable in Cornwall and West Devon.

Barn conversions

The South West has a large number of barn conversions, particularly across Devon, Somerset, and the Cotswolds fringe. Our guide on selling a converted barn covers the full range of issues. These properties often come with agricultural tie restrictions that limit who can occupy the property (typically to those employed in agriculture or forestry). Planning conditions attached to the original conversion may also restrict use as a holiday let or second home. Building regulation compliance is another consideration — older conversions may not meet current standards, and buyers will want to see completion certificates. Check your planning conditions and any restrictive covenants before listing, and disclose them on the TA6 form.

Pre-listing checklist for South West sellers

Use this checklist to make sure you have covered all the key steps before putting your South West property on the market. Completing these tasks upfront can save 4–6 weeks once you accept an offer. For a full breakdown of the costs involved, see our conveyancing costs breakdown.

1. Instruct a solicitor or conveyancer early — get them working on your title deeds and legal pack as soon as you decide to sell, not after you accept an offer.
2. Check your EPC — you need a valid Energy Performance Certificate before marketing. EPCs last 10 years and cost £60–£120 to renew.
3. Complete the TA6 property information form — this is the most detailed form your solicitor will ask you to fill in. The more thoroughly you complete it upfront, the fewer follow-up enquiries you will face.
4. Complete the TA10 fittings and contents form — decide what is included in the sale and what you are taking with you, and document it clearly.
5. Check whether your property is in a non-coal mining area — if you are in Cornwall or parts of Devon, a non-coal mining search is likely to be required. Consider ordering it in advance.
6. Get a radon report — if your property is in a radon-affected area (most of Devon, Cornwall, and parts of Somerset), order a radon report before listing. This costs £30–£45 and returns within 48 hours.
7. Verify your thatched roof condition — if your property is thatched, obtain a thatch condition report noting the last re-thatch date, thatch material, and any repairs needed.
8. Check coastal erosion risk — if your property is near the coast, review the relevant Shoreline Management Plan and check the Environment Agency's erosion risk maps.
9. Confirm your CGT position — if the property is a second home or holiday let, take tax advice on your likely Capital Gains Tax liability before setting a price.
10. Gather planning and building control documents — collect completion certificates, listed building consents, and any planning permissions for extensions, loft conversions, or other works.
11. Check for agricultural ties or covenants — particularly relevant for barn conversions, rural properties, and former farm buildings. These can restrict who buys the property and how it is used.
12. Order your title deeds from the Land Registry — your solicitor will need the official copies. If the property is unregistered (more common with older rural properties in the South West), this process takes longer.
13. Check your insurance policies — particularly important for thatched and coastal properties. Make sure cover is current and adequate. Buyers will ask for evidence.
14. Obtain flood risk information — if your property is in or near a flood zone (Somerset Levels, coastal areas, riverside locations), check your flood risk assessment and any flood mitigation measures you have in place.
15. Review your broadband and mobile coverage — rural South West properties often have limited connectivity. Buyers increasingly ask about this, and you should disclose it on the TA6 form. Check the Ofcom coverage checker for your postcode.

Stamp duty at South West prices

Understanding how much stamp duty your buyer will pay helps you gauge affordability at your asking price. The following table shows Stamp Duty Land Tax at the average South West price of £320,000, using the post-April 2025 rates. For tips on how stamp duty interacts with selling and buying simultaneously, see our guide on how to sell your house fast.

The additional property surcharge is particularly relevant in the South West given the high proportion of holiday homes and second homes. If your likely buyer pool includes second-home purchasers, be aware that they face a £22,000 SDLT bill at this price point, which may influence their offer.

Tips for a faster sale in the South West

The South West's 19–22 week average sale time can be shortened significantly with the right preparation. Here are region-specific steps that make the biggest difference.

• Commission a radon report before listing. At £30–£45 with a 24–48 hour turnaround, this is one of the cheapest and fastest ways to remove a potential sticking point. If radon levels are below the action level, this reassures your buyer immediately. If they are elevated, you have time to discuss mitigation before the buyer raises it as a concern.
• Prepare your non-coal mining search results. If your property is in a tin or clay mining area, ordering this search in advance (£40–£60, 2–5 days) means your buyer's solicitor can review it immediately rather than adding it to their to-do list.
• Have your thatch survey ready. If you are selling a thatched property, a recent thatch condition report from a qualified thatcher will answer most buyer questions before they are asked. Include the re-thatch date, material type, and expected remaining lifespan.
• Get a coastal erosion assessment for cliff-edge properties. Check the Environment Agency's National Coastal Erosion Risk Mapping and download the relevant Shoreline Management Plan extract. If your property is not at risk, this is a selling point. If it is, transparency builds trust and avoids late-stage withdrawals.
• Instruct your solicitor before you find a buyer. Getting your legal pack prepared — title deeds, TA6, TA10, and relevant searches — before you accept an offer can save 4–6 weeks of conveyancing time.
• Be upfront about holiday-home or second-home status. If the property is a second home, disclose this clearly and address CGT implications with your accountant before listing. Buyers and their solicitors will discover the status during conveyancing, so transparency from the outset builds confidence.
• Check broadband and mobile coverage. Rural South West properties often have slower broadband speeds. Buyers increasingly check this before viewing. If your property has good connectivity, highlight it. If not, mention any planned infrastructure upgrades in your area.

The common thread across all these tips is preparation. The South West has more region-specific searches and disclosures than most parts of England. Addressing them before listing, rather than reacting to them after your buyer's solicitor raises enquiries, is the single most effective way to reduce your time to completion.
