Quick answer
New gas installations in new-build properties must be notified to Building Control, which Gas Safe registered engineers do directly under the government’s official notification scheme. Buyers and developers should receive a Building Regulations compliance certificate, a commissioning checklist and a Benchmark log for the boiler, confirming the work was carried out and signed off correctly.
Key takeaways
- Gas Safe operates the official scheme for notifying Building Control of new domestic gas installation work under Building Regulations.
- A new-build buyer should receive a Building Regulations compliance certificate, a commissioning checklist and a Benchmark log book.
- New-build gas work involves multiple parties, the developer, Building Control and often a warranty provider, unlike a straightforward replacement on an existing home.
- If buying a recently built home, ask the developer or your solicitor to confirm the gas installation was properly notified.
- Missing notification paperwork is worth querying before completion, not after you move in.
New-build properties go through a more layered sign-off process than most people realise, and gas installations are a good example. The work itself is similar in principle to any other gas installation, but the paperwork trail and who is responsible for what looks quite different.
How new gas installations get notified to Building Control
Under Building Regulations, any new gas installation, including a first fix in a brand-new property, must be notified to Building Control, either through the local authority directly or through a competent person scheme. Gas Safe Register operates the official government scheme for this in relation to gas work, meaning a Gas Safe registered engineer can self-certify the work and notify Building Control on the developer’s behalf, without the local authority needing to send its own inspector out separately. This is the mechanism that ultimately produces the Building Regulations compliance certificate for the gas installation.
What documentation a new-build buyer or developer should receive
For a new-build property, you should expect to receive, either directly or via your solicitor:
- A Building Regulations compliance certificate confirming the gas installation was notified and meets current regulations
- A commissioning checklist showing the boiler and gas appliances were set up and tested correctly on completion
- A Benchmark log book for the boiler, completed by the installing engineer, which also underpins the manufacturer’s warranty
These documents are separate from, but related to, the property’s overall NHBC or new-home warranty, which typically covers structural and major systems issues for a set number of years after completion.
Why this differs from a standard installation on an existing property
Replacing a boiler in an existing home is also notified to Building Control under the same competent person scheme, but it usually involves one straightforward relationship: homeowner and engineer. A new build is more layered. The developer commissions the work, often through a subcontracted gas engineering firm, Building Control oversight runs alongside the wider construction sign-off, and a home warranty provider may also have its own inspection requirements. The new boiler installation itself follows the same safety standards either way, but the chain of paperwork and responsibility is longer, which is exactly why it is worth checking rather than assuming everything has been filed correctly.
What to check if buying a recently built home
If you are buying a home that was built in the last few years, it is worth confirming the gas installation paperwork exists and matches the property, rather than taking it on trust. Ask your solicitor to request the Building Regulations compliance certificate for the gas work as part of the conveyancing enquiries, and check that a Benchmark log book was left with the property. If anything is missing, it can usually still be traced through Gas Safe Register’s records or the original installing company, but it is far easier to resolve before completion than afterwards.
What happens if gas work was not properly notified
Gas work that was carried out but never notified to Building Control is a genuine compliance gap, and mortgage lenders or solicitors acting for a subsequent buyer can flag it during a future sale, sometimes requiring retrospective certification to resolve. It does not necessarily mean the work itself was unsafe, but it means there is no official paper trail confirming it meets Building Regulations, which is exactly the kind of loose end that causes delays further down the line.
“I run the Estates & Facilities at Holmes Chapel High School. I called Gasmaster Plumbing & Heating from Stoke on Trent, for an emergency call out, due to no gas getting to our school restaurant causing issues to feed over 1,300 students. They came out to me very quickly… I also use Gasmaster for my annual commercial gas safety service in the school restaurant. I would highly recommend Gasmaster if anyone was looking for this kind of work”

Frequently asked questions
Who is responsible for notifying Building Control on a new-build gas installation?
The Gas Safe registered engineer or firm carrying out the work notifies Building Control, typically through the Gas Safe notification scheme, on behalf of the developer commissioning the installation.
What documents should I be given when I complete on a new-build home?
You should expect a Building Regulations compliance certificate for the gas work, a commissioning checklist, and a Benchmark log book for the boiler. Ask your solicitor to confirm these were provided if they are not included in your completion pack.
Is new-build gas safety notification different from a standard boiler replacement?
The notification mechanism is the same competent person scheme, but a new build typically involves more parties, including the developer and a home warranty provider, making the overall paperwork trail longer.
What should I do if I cannot find the gas safety documents for my new-build home?
Contact your solicitor or the developer to request copies, or check with Gas Safe Register, who hold records of notified work. It is best resolved as early as possible rather than left until you need it.
Does a new-build boiler still need an annual service like any other boiler?
Yes. New-build boilers need the same annual servicing as any other boiler to remain safe and to keep the manufacturer’s warranty valid, regardless of how recently the property was built.
