Do not use Tradehand or any booking site for that. Get everyone out, avoid electrical switches and naked flames, and call the National Gas Emergency Service on 0800 111 999 in Great Britain (0800 002 001 in Northern Ireland).

Is a boiler service the same as a landlord CP12?

No. An annual boiler service checks and maintains the appliance. A landlord gas safety record (often called a CP12) is the landlord's statutory safety check of appliances and flues they are responsible for, at intervals of not more than 12 months. You can book either through a Gas Safe engineer; say which document you need.

Must the engineer be on the Gas Safe Register?

Yes. Anyone carrying out gas work in the course of business must be a member of the class of persons approved by the HSE, which is the Gas Safe Register. Working on gas outside that approval is a criminal offence.

Paid plans from £25 a month add the Assistant. Basic payment fees on your own jobs: From 1.25% + 20p, deducted automatically when the customer pays.

How do I find a Gas Safe engineer for a boiler service and book it

Service, repair or gas emergency

Situation	What to do	Not this
Smell of gas / CO alarm	Call 0800 111 999	Do not book a routine visit online
Annual boiler service	Tradehand /quote → Gas Safe engineer	Not a substitute for a landlord CP12
Boiler breakdown (no gas smell)	Tradehand /quote for a repair visit	Still confirm Gas Safe before work starts

Gas work in the course of business must be done by someone on the Gas Safe Register. HSE states that anyone working on gas appliances in domestic premises must be Gas Safe registered.

Steps to book a Gas Safe boiler service

Rule out a gas emergency first

If you smell gas, hear gas escaping, or a carbon monoxide alarm is sounding, do not book a routine service. Open doors and windows, avoid switches and naked flames, leave the property and call the National Gas Emergency Service on 0800 111 999 in Great Britain (0800 002 001 in Northern Ireland).

Describe a boiler service on /quote

For a planned annual service or a non-emergency repair, open /quote on Tradehand. Say boiler service (or the fault), boiler make if known, and your area.

Book a Gas Safe engineer and check the licence

Pick a claimed local heating or gas listing, then confirm the engineer on the Gas Safe Register before they arrive. Registration is a legal requirement for gas work, not a Tradehand badge.

Keep the service record

Ask for the service checklist and any parts replaced. Landlords still need a separate annual landlord gas safety record (CP12) for rented homes; a manufacturer service visit is not automatically that certificate.
