Do you need a new gas safety certificate for a new tenant?

London lettings move fast. In Haringey, 35.6% of households rented privately at the 2021 Census, well above the England figure of 20.5% (ONS, Haringey). In Tottenham and Wood Green, flats change hands between tenants often, and landlords regularly ask the same question: does the new tenant need a new gas safety certificate? This guide gives the HSE answer and the practical one.

The HSE answer

HSE deals with this directly. A gas safety check record is valid for 12 months from the date of the check. If a new tenancy begins within that 12 month period, the record stays current and you can give a copy to the new tenants (HSE, what if).

Two other HSE rules sit alongside that:

• The new tenant must receive the record before they move in.
• Before any new lease starts, the checks must have been done within one year before the start date (HSE).

So legally, a record from March can cover a tenancy that starts in September. It will still need renewing by the following March.

The practical answer: check what changed

HSE also says landlords must make sure all appliances and flues are safe before letting the property again. The maintenance duty is separate from the paperwork duty. A valid record does not prove nothing has happened since.

HSE lists the things that go wrong between tenancies:

Risk between tenancies	What HSE says
Tenant removed a cooker or heater	May have left open ended pipes
Emergency control valve left off	Turned off at the meter and never checked
Tenant left their own appliance	Clarify ownership, then remove or check it
Property empty for a while	Possible tampering or vandalism, consider a new check
Pipework	HSE recommends inspection and a soundness test before the next let

If any of those apply, a fresh check before the new tenant arrives is the sensible route. It also resets the 12 months, which some landlords prefer so the record and the tenancy line up.

Tottenham flats: the common snags

Much of Tottenham and Wood Green is Victorian and Edwardian terraces, including the Noel Park estate, about 2,000 terraced homes built by the Artizans company from around 1881 (Haringey Council, Noel Park appraisal). Many of these houses are now split into an upper and lower flat.

In a split house, the gas meter for the upstairs flat is often downstairs, in a shared hall cupboard or under the stairs. When a tenant moves out and turns the gas off at their emergency control valve, the next tenant may not know where to turn it back on. Worse, the outgoing tenant may have disconnected a cooker and left the bayonet point, the push in hose connector, damaged or uncapped.

A new check catches these. It also means you can show the incoming tenant where the meter and valve are, which is good practice for any flat. See our guide to finding your gas emergency control valve.

Why you cannot backdate a record

Some landlords discover the record has lapsed only when a new tenant asks for it. A record cannot be fixed by backdating. HSE says the record must contain the date on which the appliance was checked, plus the engineer’s name, registration number and signature (HSE, records). A record with a false date is not a valid record. Any engineer asked to produce one should refuse.

If the record has expired, book a check before the tenant moves in. If they are already in, book it immediately and give them a copy within 28 days.

A simple routine between tenants

1. When notice is given, look at the date on the current record.
2. If it will run out within the first two months of the new tenancy, book a new check now, using the two month early window if it suits.
3. After the old tenant leaves, check every appliance is still there and nothing has been disconnected.
4. If anything has changed, or the property has been empty, book a fresh check.
5. Send the new tenant the record before move in day, and note how you sent it.

Carbon monoxide alarms on change of tenancy

Since 1 October 2022, landlords in England must check that smoke and carbon monoxide alarms are working on the day a new tenancy starts (GOV.UK). A carbon monoxide alarm is needed in any room used as living accommodation with a fixed combustion appliance, apart from gas cookers. Testing the alarm can be done at the same handover visit.

Booking a check

London Gas Engineers carries out landlord gas safety certificates in Tottenham, Wood Green and across north and east London. Whoever you use, the rule is the same: ask to see the engineer’s Gas Safe ID card and make sure the work categories on the back match the appliances in your property.
