No Building Regulations Certificate For Past Work
You are selling, remortgaging or insuring, and there is no paperwork for an extension, a removed wall or a loft conversion.

What's happening?
The Building Regulations 2010 cover construction, extension and many alteration projects, and the paperwork proving compliance is what a buyer's solicitor asks for. There are two normal routes to that paperwork: an application to a building control body, ending in a completion certificate; or, for certain work, a registered competent person self-certifying and issuing a certificate. Missing paperwork does not automatically mean the work is unsafe. It means nobody independent has confirmed it, and that is what makes a conveyance stall. The fix is to establish what was actually done, get it inspected where possible, and regularise it — or, where the work is genuinely non-compliant, put it right.
What usually causes it?
- Work done by a previous owner with no application made to building control
- An extension or conversion built under permitted development, with the owner assuming planning permission covered building regulations too — they are separate consents
- Structural work such as removing a load-bearing wall carried out without notification
- Replacement windows, a boiler, a fuse box or electrics fitted by someone not registered with a competent person scheme, so no certificate was issued
- An application made but never signed off, so the file was closed without a completion certificate
- A loft or garage conversion done as 'storage' and later used as a room
- Certificates issued but simply lost between owners
Is it dangerous?
The paperwork is not the risk; the unknown work is. Some categories matter far more than others. Removed structural walls, loft conversions and altered stairs affect structure, escape and guarding, and Approved Documents A, B and K exist precisely for those. A missing window certificate is a much smaller matter. Treat unnotified structural work and anything affecting means of escape as worth inspecting on its own merits, regardless of whether you are selling.
Can I fix it myself?
Some of the groundwork, yes. Ask the local authority building control department what records exist for the address — they will search. Check the competent person register for any installer's certificate for windows, electrics or heating. Gather invoices, plans and photographs of the work. What you cannot do is issue your own certificate, and an indemnity insurance policy offered during a sale covers a buyer against enforcement action; it does not confirm the work is safe or compliant.
When should you call a builder?
Call a builder to open up and inspect where structural work was done without records — a beam over a removed wall, a loft floor, a lintel, an altered stair. Talk to the local authority building control body about a regularisation application, which is the route for work already completed. Where the work involved gas, electrics or a heating system, the relevant registered installer is the one who can inspect and certify.
What will the builder actually do?
- Identify from the fabric what was actually built, which is often different from what the seller believes
- Open up locally to expose beams, bearings, lintels, joists and insulation so the work can be assessed
- Bring in a structural engineer to check and, where needed, to design remedial support
- Prepare drawings and calculations to support a regularisation application to building control
- Carry out the remedial work the building control body requires so it can be signed off
- Coordinate the registered installers whose certificates are needed for electrics, gas or heating
