You've spent £25,000 on a quality conservatory. Another £40,000 on a side extension. Your home is now worth significantly more, and you've finally decided to sell. Then your estate agent mentions something that makes your stomach drop: your conveyancing solicitor needs to verify that all the work was done properly. Planning permission. Building Regulations sign-off. Guarantees and insurance certificates. Suddenly, you're wondering if you should have chosen your solicitor more carefully.
Most home improvement professionals understand this problem intimately. You build something brilliant, everything works perfectly, but when ownership changes hands, the legal side can become complicated fast. A solicitor who's never handled a property with a substantial extension might miss something that costs you thousands in renegotiation or, worse, keeps the sale from completing at all.
Let's be clear about what conveyancing actually is. It's the legal process of transferring ownership from one person to another. That's it. But when your property has a conservatory built in 2015, a loft conversion from 2018, and a kitchen extension that's never had proper Building Regulations certification, your conveyancer's job suddenly becomes far more complex.
A solicitor who works primarily with standard properties might treat missing paperwork as a minor issue. They might suggest waiting for indemnity insurance and moving on. But indemnity insurance is expensive, typically £300 to £800 per missing certificate depending on the work involved. Even then, a future buyer's mortgage lender might refuse to accept it. Your sale stalls. Your chain collapses. You're back to square one.
By contrast, a solicitor experienced in this sector understands that many improvements lack perfect documentation because they were done sensibly, properly, and simply never formally signed off. They know which local authorities are strict, which are pragmatic, and which certificates genuinely matter versus which are bureaucratic afterthoughts.
Start by asking directly: how many property sales have they handled where the property had extensions or conservatories? Listen to the answer. If they hesitate or give you a vague number, that's a red flag. You want someone who can rattle off a number with confidence because they've dealt with it dozens of times.
Ask them specifically about Building Regulations compliance. Do they routinely deal with properties where compliance certificates are missing? Have they negotiated with Local Authorities to obtain retrospective certification? These are the conversations that separate experienced practitioners from those just going through the motions.
Here's another useful question: what's their relationship like with local authority Building Control teams? A solicitor who's built relationships with the relevant departments can often speed up enquiries or get clarification on whether a particular piece of work genuinely needs certification. Personal relationships matter in the conveyancing world, though you wouldn't know it from how formal everything looks.
Ask about planning permission too. Many extensions require it. Some don't. A solicitor should be able to tell you confidently whether your 2005 conservatory would have needed permission under the rules that applied in 2005, or whether it would qualify as permitted development. They should know which councils changed their policies and when.
Be aware that standard conveyancing fees don't account for the extra work involved in verifying home improvements. Most firms charge a flat rate for straightforward sales, often £800 to £1,500. But if your property needs investigation, that's going to take longer.
Ask upfront about how they charge when issues arise. Some solicitors build in contingency time. Others charge hourly for additional work once the basic fee is exceeded. Neither approach is wrong, but you need to know which one applies to you and get it in writing.
Don't automatically go for the cheapest option. A solicitor charging £500 less than their competitors might be cutting corners or simply underestimating the work involved. When complications emerge halfway through, they'll either rush to solve them or, worse, ask you to pay additional fees you weren't expecting.
Ask for references, and actually contact them. Ideally, speak to someone who's sold a property similar to yours: something with substantial alterations or extensions that required investigation. Ask whether the solicitor was proactive in identifying potential issues early, or whether problems only emerged later.
Look for online reviews on legal directories. The Law Society's Find a Solicitor tool lets you see regulatory information and complaints history. It's not glamorous reading, but it matters. If a firm has received multiple complaints about communication or missed deadlines, that's telling you something.
Most importantly, speak to the individual solicitor who will actually handle your conveyance, not just the firm's receptionist. This person needs to understand the specifics of your property and your circumstances. They need to listen when you explain the history of your conservatory or extension.
Good conveyancing solicitors dealing with improvement complications will start investigations early. Ideally, before your property even reaches the open market. They might suggest getting certificates in order now, rather than waiting for a buyer's surveyor to flag problems later.
This costs money upfront. But £500 now to get a retrospective Building Regulations certificate is far cheaper than renegotiating your sale price because a buyer's mortgage lender won't proceed without one.
Ask your solicitor how long investigations typically take on properties like yours. If they're saying it's fine and can wait until offers come in, be sceptical. That's the conveyancing equivalent of hoping your surveyor won't notice structural issues.
You want a solicitor who treats your property's improvements as normal, manageable issues rather than problems to be minimised or hidden. You want someone who asks good questions, explains the implications clearly, and knows how to navigate Local Authority procedures because they've done it many times before.
It's worth paying a bit more for experience and confidence rather than saving money with someone learning on your transaction. Your home improvements are valuable. The person protecting your interests legally deserves to understand that value.
