What homeowners ask heating engineers

With what our guides tell them. Answer these in your quote, and later on your listing.

Are you on the Gas Safe Register for this work?

By law, anyone who works on gas in your home must be on the Gas Safe Register. Ask to see each engineer’s Gas Safe card and check it lists the work you need.

Have you checked the water pressure for a combi?

Homeowners moving to a combi are told to ask whether the mains flow and pressure were measured, and whether the gas pipe from the meter is big enough for the new boiler.

Should I get a heat pump instead?

Our boiler guide compares them: an air source heat pump for a 3 bed home is about £12,000 to £15,000 before the £7,500 Boiler Upgrade Scheme grant. If you fit both, add Heat pumps to your trades.

What homeowners will ask you to confirm

From the checklist in our new boiler guide:

Model: Boiler model and output.
Warranty: Length and conditions.
Extras: Filter, flush, controls and flue.
Water supply: Mains flow and pressure measured, if you are moving to a combi.
Gas pipe: Whether the pipe from the meter is big enough for the new boiler, and the price for a bigger one if not.
Oil tank: For an oil boiler: whether the tank and oil line are kept, and their condition.
Carbon monoxide alarm: Fitted with the new boiler.
Certificates: Gas Safe or oil scheme registration, and building regulations notification.
Hard water: In a hard water area, whether a scale reducer or other water treatment is fitted on the water feed to a combi, to slow the build-up of limescale.
Unvented cylinder: If an unvented cylinder (fed from the mains, with no tank in the loft) will be worked on: the installer's unvented qualification, or their competent person scheme registration for unvented systems. Gas Safe registration doesn't cover unvented cylinders.
Commissioning and warranty: The Benchmark commissioning checklist filled in and left with you, and who registers the boiler's warranty with the maker.

Only if you do gas work: Gas Safe Register. By law, anyone who works on gas in your home must be on the Gas Safe Register. Ask to see each engineer's Gas Safe card and check it lists the work you need. The law and the registers
Who runs the business: an ID check, or a code letter for a company’s director.

Badges you can add (not needed to appear): Oil heating competent person scheme, Heating and hot water competent person scheme, Electrical competent person scheme and TrustMark, and insurance.
