What a Gas Safety Certificate Covers
A gas safety certificate, also called a CP12 or Landlord Gas Safety Record, records that the gas appliances in a rental have been checked. It's the paper a landlord holds to show the annual check was done.
London lets are rarely simple. You've got Victorian and Edwardian terraces in Clapham and Wandsworth, converted villas in Richmond, and mansion blocks around Kensington. We know the jobs those buildings throw up.
The appliances and parts checked
- Boilers, cookers and gas fires
- Flues and ventilation
- Safety devices on each appliance
- Visible pipework serving them
Flats, houses and basements
A first-floor flat in a stucco-fronted townhouse isn't the same visit as a post-war estate flat in Stratford. Access, flue routes and ventilation differ. Basement flats need extra thought too, since London basements are vulnerable to sewer flooding and local controls shape what's fitted there.
If an appliance fails
A failed appliance isn't the end of the job. You'll be told what's wrong, and any repair gets a written price after we've described the work with you.

Legal Requirements and Certificate Delivery for London Homes
If you let a home, the annual gas safety check by a Gas Safe registered engineer is a legal duty. You must also give tenants a copy of the record. Keep your own copies too.
Who may do gas work? The law requires anyone doing gas work to be competent, and anyone doing it as a business to be Gas Safe registered; HSE and Gas Safe Register advise using a registered engineer. That's advice you should follow when you pick who does your check.
Do you need a certificate to sell a house? That's a different matter from the landlord duty, and it's the buyer's survey that usually asks about appliances. Tenants without a record can raise it with the landlord, and a landlord who skips the check is exposed.
We've set the work out plainly. Customers in London and gas safety certificate in City of Westminster alike come to us for this, from mansion blocks near Hyde Park to flats around Victoria Tower Gardens.

Gas Safety Certificate in London: Your Questions Answered
Do I need a gas safety certificate to sell a house in London?
The annual check is a landlord duty, not a sales rule. Buyers and their surveyors may still ask about boilers and appliances. If you're letting out a London property before selling, keep your records. Ring us and we'll talk through the property.
Can a tenant in London take action if their landlord has no gas safety certificate?
Tenants are entitled to a copy of the record, so they can raise it with the landlord first. It's a legal duty on landlords. If you're a landlord, don't wait: describe your property to us and get a quote.
Does a Victorian terrace or mansion block change the gas check?
Yes, the visit follows the building. Older terraces in Clapham or Wandsworth and mansion blocks in Kensington differ in flues, access and ventilation. Tell us the property type when you ring and we'll price the job in writing.
