This one catches decent, careful people out constantly, and it almost never surfaces until there is a buyer, a chain and a deadline.
When a new gas boiler is installed, the installation has to be notified to the local authority within 30 days. A Gas Safe registered engineer normally does this automatically through the register, and a Building Regulations Compliance Certificate follows. That certificate is the proof the installation met Building Regulations.
The document people think they have
The annual service record is not that certificate. It confirms the appliance was checked and is operating safely at that moment. It says nothing at all about whether the original installation was ever notified.
So a homeowner opens the drawer, finds a stack of gas paperwork, and reasonably assumes they are covered. The gap only appears when someone goes looking in the right place.
How it surfaces, and what it costs
During pre-contract enquiries the buyer's solicitor reviews the local authority searches and the seller's replies. If the boiler was fitted during a renovation and the installer never logged it, there is nothing on the register to find.
Lenders are risk-averse about uncertified gas and heating work and will routinely decline to release funds until it is resolved. The seller is then trying to trace the original installer, who may have retired or closed the business, or arranging a retrospective inspection. Either route takes weeks, at the exact point in a transaction when weeks are the thing nobody has.
- Weeks of delay at the worst possible moment in a chain
- Costs for retrospective inspection or a regularisation application
- Price renegotiation once the buyer knows you are stuck
- Buyers walking away entirely
Where we fit — and where we do not
PRAVISE is not a Gas Safe registered business. We do not inspect, test or certify gas appliances and we cannot issue anything relating to them. That work belongs to a registered engineer, full stop.
What we do is the paperwork and process side. We go through the folder with you, work out which documents you actually hold, which ones should exist and do not, and what the realistic route is to close each gap — including telling you when the answer is simply to get the right registered person out. It is a compliance sense-check, not a technical inspection, and the value is in doing it now rather than under pressure.
Fair to the trade as well
Plenty of installers register everything properly and hand the certificate over on the day. Where it goes wrong is usually a larger renovation with several trades, where the boiler is one item among fifty and the notification quietly falls through the gap between the builder and the subcontractor.
The fix is the same for both sides: agree at the start of the job which certificates are expected, from whom, and that they arrive before the final payment does.
