Selling a House Without a Building Warrant in Scotland: What to Do

It's the most common reason a Scottish house sale stalls: work was done — by you or a previous owner — with no building warrant or completion certificate, and it surfaces during the sale.

Can you still sell?

Usually, yes

But the missing paperwork must be dealt with — buyers' solicitors will ask.

Best fix

Sort it before you market

Retrospective warrant or a letter of comfort, depending on the age of the work.

Why it matters

In Scotland, most alterations need a building warrant and a completion certificate. When you sell, the buyer's solicitor asks for these for any obvious alterations — a knocked-through wall, a converted garage, an extension. If they're missing, the buyer's lender and insurer may take a view, and the deal can stall or the price drop.

Your options

Retrospective ("late") building warrant — you apply after the fact. The council can require finished work to be opened up so it can be inspected. Best for more recent work.
Letter of comfort / property inspection report — for older work, many Scottish councils will, for a fee, inspect and confirm they won't take enforcement action. It's not a warrant, but it reassures buyers and lenders.
Indemnity insurance — sometimes used as a stopgap, but it doesn't make the work compliant and won't satisfy every buyer.

🚨 The expensive version is discovering this under a sale deadline. Sort it before you list — it's cheaper, calmer and keeps your buyer.

💡 How MPS helps: we assess what was done, advise whether a retrospective warrant or a letter of comfort is the right route, prepare drawings and manage the council process — so your sale isn't held hostage to old paperwork.

Frequently asked

The work was done 15 years ago — is it fine now?

Time doesn't create a completion certificate. Fifteen years of not falling down isn't proof of compliance. A letter of comfort is usually the pragmatic route for old work.

We're buying a house with no warrant for the extension — what do we do?

Ask the seller to obtain a retrospective warrant or letter of comfort before completion, or price it in. Get your solicitor's advice — don't just accept "it's been fine for years".

Does this apply to internal work too?

Yes — removed load-bearing walls and garage conversions are the classic culprits, not just extensions.
