🏡 Extensions, Loft Conversions & Hidden Selling Pitfalls – What You Need to Know! ⚠️

🏡 Extensions, Loft Conversions & Hidden Selling Pitfalls – What You Need to Know! ⚠️

Many homeowners make improvements to their property—whether it’s an extension, loft conversion, orangery, or garage conversion—without realising the potential legal and financial consequences when it comes time to sell.

At Keystone, we frequently encounter delays and complications caused by missing planning permission or building regulation compliance certificates. Here’s what you need to know and how it could affect your sale.
 
Planning Permission vs. Building Regulations – What’s the Difference?
 
Many people confuse planning permission and building regulations, but they are separate legal requirements:
 
✅ Planning Permission – Determines whether you’re allowed to build something based on local planning policies (e.g., impact on neighbours, aesthetics, environmental concerns). Some works fall under permitted development, meaning formal permission isn’t required.
 
✅ Building Regulations Compliance – Ensures the work meets safety, structural integrity, fire regulations, energy efficiency, and other essential legal standards. Even if planning permission isn’t needed, a Building Regulations Compliance Certificate is usually required for major alterations.
 
👉 Key point: Even if an extension or conversion was built years ago, missing building regulation approval can cause problems when selling—especially with mortgage lenders and cautious buyers.
 
What Happens When There’s No Building Regulations Approval?
 
When selling a property, buyers (and more importantly, their mortgage lenders) will ask for proof that any structural work meets legal safety standards. If this can’t be provided, it can lead to:
 
❌ Lenders refusing mortgages – Some banks won’t lend against properties with unregulated work, meaning the buyer may struggle to secure finance.
❌ Buyers pulling out – Buyers may worry about safety risks, future problems, or difficulty selling in the future.
❌ Expensive delays – Sales can be delayed while the seller tries to obtain retrospective approval or negotiate indemnity insurance.
 
Can an Indemnity Policy Solve the Problem?
 
In some cases, homeowners can take out an indemnity insurance policy, which protects the buyer (and sometimes their lender) against enforcement action from the local council. However, this comes with limitations:
 
⚠️ Indemnity insurance is NOT a guarantee of safety or compliance – It simply protects against legal enforcement, not structural defects.
⚠️ Some mortgage lenders won’t accept indemnity policies – Especially if the missing approval relates to serious safety concerns (e.g., fire regulations in a loft conversion).
⚠️ The policy is invalid if the council is informed – If the seller has already contacted the local authority for retrospective approval, indemnity insurance is no longer an option.
 
What Can Be Done if Approval is Missing?
 
If building regulation approval wasn’t obtained at the time of construction, sellers have two main options:
 
1️⃣ Retrospective Building Control Approval (Regularisation Certificate)
  â€˘     If the work was carried out after 1985, the local authority may issue a Regularisation Certificate, confirming the work now meets modern building standards.
  â€˘     This usually involves an inspection (which may require uncovering parts of the work, such as removing walls or ceilings to check insulation, wiring, or foundations).
  â€˘     Downside: If the work isn’t up to standard, costly remedial work may be required.
 
2️⃣ Selling Without Approval (Buyer’s Choice)
  â€˘     Some buyers may accept an indemnity policy, but this depends on their lender and legal advice.
  â€˘     In some cases, a price reduction or seller contribution to future compliance costs may be negotiated.
 
Our Advice to Homeowners
 
🔹 Before selling, check you have the correct paperwork – especially for extensions, loft conversions, and structural changes.
🔹 If documents are missing, don’t wait until a sale is agreed – speak to an estate agent, solicitor, or building control expert early to explore your options.
🔹 Be upfront with buyers – Surprises cause delays and uncertainty, which can make buyers walk away.
 
At Keystone, we’ve successfully helped sellers navigate these issues, whether through securing retrospective approval, negotiating with buyers, or ensuring all options are explored early in the process. If you’re thinking of selling and have made alterations to your home, we can guide you through the process to avoid unnecessary delays.
