When a boiler packs in on a cold morning in Bolton or Chorley, the homeowner isn't browsing for fun. They want to know three things fast. Are you properly registered? Do you cover my area? How quickly can I reach you?
A heating engineer website that answers those questions clearly turns a worried search into a booked job. Here's what to put on it.
1. Your Gas Safe details, shown properly
By law, anyone who works on gas fittings for a living has to belong to the class of persons approved by the Health and Safety Executive, and it's an offence to falsely pretend to be a member [1]. In practice, that means being Gas Safe registered: HSE guidance, for example, tells landlords to use a Gas Safe registered engineer [2].
So make your registration easy to check:
- Write "Gas Safe registered" in plain text near the top of the page
- Show your registration number
- Link to the Gas Safe Register so customers can check it themselves
- Only use the Gas Safe logo from your own registration pack, while you're registered
If you also work on oil or solid fuel, list the schemes you're registered with for that work too, and nothing you're not.
2. Separate pages for the work you want more of
"Heating and plumbing" on its own doesn't tell anyone much. Give your main services a page or a clear section each:
- Boiler installation and replacement: the brands you fit, what a typical install involves, and what affects the price
- Boiler repairs and breakdowns: your hours, and whether you offer same-day or emergency call-outs (only if you really do)
- Servicing: what an annual service covers
- Landlord gas safety checks (see below)
- Heat pumps, if you're qualified to fit them (see below)
Separate pages help customers find the right thing, and they give Google a clear idea of what you do.
3. A landlord page that saves them homework
Landlords are a steady source of repeat work. A short, accurate landlord page is useful to them. According to the HSE, landlords must:
- have an annual gas safety check carried out by a Gas Safe registered engineer [2]
- keep a record of the check for 2 years [2]
- give existing tenants a copy within 28 days of the check, and new tenants a copy before they move in [2]
Explain how you book these, how you send the record, and whether you can remind landlords when the next one is due.
4. Building regulations sign-off
Gas work is one of the types of building work installers can self-certify instead of applying for building regulations approval. The government lists Gas Safe Register for gas work, and says its installers in practice have the same responsibilities for complying with building regulations as competent person schemes [3]. A line explaining that you handle the paperwork, and what certificate the customer should expect afterwards, takes a worry off their mind.
5. Heat pumps and the Boiler Upgrade Scheme (only if you install them)
If you fit heat pumps, this is worth a page of its own. Under the government's Boiler Upgrade Scheme in England and Wales, homeowners can currently get £7,500 towards an air source or ground source heat pump [4]. Until March 2027, there's an extra £1,500 for homes heated by oil or LPG with no mains gas connection [4].
Two points to state accurately:
- The installer applies for the grant on the homeowner's behalf, and must be MCS certified [4]
- Grant amounts and rules can change, so link to the GOV.UK page and check it before you quote
Don't mention the scheme at all if you're not MCS certified. It would mislead customers about what you can offer.
6. Make contact easy on a phone
More than half of UK web traffic now comes from mobile phones: around 54% in September 2026, according to StatCounter [5]. Someone with no hot water is very likely searching on their phone. Put a tap-to-call button, your email address and a short enquiry form near the top, and keep your hours clear.
7. The areas you cover
List the towns and estates you actually cover, for example "Horwich, Westhoughton, Blackrod and Bolton". Write it for people rather than stuffing a list of 40 towns at the bottom. Avoid making near-identical pages for every town; Google treats pages built only to rank for similar searches as doorway abuse [6]. Our local SEO guide explains what to do instead.
8. Real photos and genuine reviews
Photos of your own neat installs, your van and your team beat any stock image of a gleaming boiler. Get the customer's permission before showing anything recognisable inside their home.
Ask happy customers for a review and make it easy with a link. Never offer anything in exchange. Our guide shows how: How to Get More Google Reviews (Without Being Pushy).
