Gas Certificate

Smell of gas, a stubborn boiler or a reminder from a letting agent can all prompt the same thought. People search for a gas certificate in London because they want to know that their property is safe, legal and ready for inspection. First Action is a Gas Safe registered contractor providing gas safety check visits, CP12 reports and ongoing support for landlords, homeowners and commercial property owners who need trusted certification, not guesswork.

What is a gas safety certificate in London

A landlord gas safety certificate sometimes called a gas safety record confirms that gas appliances and pipework in a property have been checked by a registered gas engineer and are safe to use at the time of inspection. During the visit, the engineer tests appliances, checks flues, ventilation and operating pressures, and looks for signs of leaks or unsafe operation.

At First Action, certificates are issued for both domestic and commercial property sites. Work is carried out by Gas Safe engineers who keep detailed records of findings so you have clear evidence for tenants, insurers and managing agents.

Do landlords need a gas certificate by law in the UK

For landlords and many business owners, an up to date gas certificate is not optional. Regulations require that gas installations and gas appliances in rental and commercial premises are checked regularly by a Gas Safe engineer. Records must be kept and made available to tenants and, when requested, to local authorities.

Failure to arrange regular gas safety inspection visits can expose landlords to enforcement action and serious financial and legal risk if an incident occurs. First Action helps reduce that risk with organised reminders, clear pricing and experienced engineers who understand the practical realities of managing rented homes and busy sites.

How often should gas appliances be checked

Most landlords arrange a gas safety check every twelve months, which is the standard interval for CP12 certification. Checks are also strongly advised after boiler replacement, major heating alterations or any suspected leak or fault.

Owner occupiers are not bound by the same rules but are encouraged to book boiler service visits regularly so appliances run efficiently and dangerous issues are picked up early. First Action offers professional inspection, gas safety record completion and gas certificate packages starting from competitive fixed prices for one, two or three plus appliances, with options for meter accuracy checks where needed.

Why choose First Action for gas certificates

First Action is a Gas Safe registered contractor with many years of experience in gas safety inspection work across London. Engineers are regularly assessed by the official registration body for the United Kingdom, the Isle of Man and Guernsey. This ongoing oversight means skills, equipment and working methods stay aligned with current legislation and best practice for residential, commercial and tenanted properties.

As a contractor that also provides electrical certificate services, First Action can combine gas and electrical compliance visits. Landlords and portfolio owners often choose this approach because it reduces disruption and simplifies administration. One contractor manages both gas certificates and electrical reports, which saves time and helps keep records consistent.
