Can you sell a house with missing planning permission?

Yes, it’s legal to sell a house without planning permission or building regulations sign-off. Mortgage lenders often refuse to fund the purchase though, until the issue is resolved. A direct cash sale can complete without waiting for that resolution.

Planning permission vs building regulations — the key difference

Sellers often confuse planning permission with building regulations approval. They’re two separate systems, handled by two separate council departments.

Planning permission covers how a building looks and how it affects the surrounding area. Building regulations cover the actual structural safety, materials, insulation, and electrics used.

Why councils treat each one differently

Planning breaches now generally carry a 10-year enforcement limit. This changed on 25 April 2024 under the Levelling-up and Regeneration Act. Older breaches, from before that date, may still fall under the previous, shorter 4-year rule. Once the relevant period passes, councils typically can’t force the work to be removed. A mortgage lender will still want the issue resolved before releasing funds, though.

Building regulations breaches also now carry a 10-year enforcement limit, extended from just 12 months in October 2023. There’s still no time limit at all if the work is deemed unsafe, though. Sellers who can’t produce a completion certificate often face real difficulty. Lenders may suspect the underlying work isn’t sound.

Why indemnity insurance often can't help

A Conveyancing Indemnity Insurance Policy is the standard fix for a missing certificate. These single-premium policies typically cost between £100 and £500. They protect the buyer and lender against a future enforcement action.

There’s a significant catch, though. These policies become void the moment the council is contacted about the issue. If a solicitor requests old records or applies for retrospective consent, the council becomes aware of the breach. Insurers then refuse cover, leaving a seller without this option.

Your realistic options for selling

Properties with planning or building regulations issues regularly see traditional sales collapse partway through. A direct cash sale avoids this risk entirely. National Property Buyers can purchase the property as it stands, without needing the issue resolved or insured first.

If you’d rather sell on the open market, choose a solicitor experienced in this kind of case. We work with a specialist conveyancing partner who regularly handles planning and building regs issues. This firm pays us a £200 referral fee for each seller we introduce. This fee isn’t added to your own legal bill. You pay the same standard market rate. We disclose this in line with National Trading Standards and Solicitors Regulation Authority guidance.
