Web Design for Gas Engineers
Two extra services a year pays for your entire website.
Run the numbers before anything else
A gas appliance service is £125. A hob and oven connection, £255. An emergency gas repair, £255. A meter relocation, £425. A power flush, £615.
Now put our pricing next to that. Seen is £29 a month — £348 a year. That’s under three boiler services.
So the question isn’t whether a website is worth it. It’s whether a proper website, a landlord page and a system that keeps your customers will bring you three extra jobs across an entire year. If it brings you one extra job a month, that’s £3,060 against £348.
That’s the maths, and it’s why we build differently for you than for a builder. A builder can throw £2,500 at a website and win it back on one extension. You need a site that’s cheap to run, converts hard, and — critically — captures every customer so they come back next year. Get that right and each new customer isn’t one £125 job, it’s £125 a year for a decade.
That’s the thing most gas engineers are sitting on and not using: a list of every boiler you’ve ever serviced. The website’s job is to keep filling it.
What actually makes money in gas
The annual service is the business. Every boiler you service comes round again. Every landlord you work for needs their certificate every year without fail, because they can’t legally let the property without one. That isn’t marketing — it’s an obligation with your name attached, provided you’re the one who remembers.
Landlords are worth more than homeowners. One letting agent with thirty properties is thirty certificates a year, at a predictable time, paid on terms. A homeowner is one service, if they think of it.
Winter is not a strategy. October to January you’re flat out and turning work away. May to August the phone barely rings. Most gas engineers market hardest in winter when they’re already busy, and go quiet in summer when they need the work. That’s backwards and it costs a fortune in idle time.
Volume trades die on lead cost. At £255 a job, paying £40 for a lead that converts one in four is a loss. Any advice that starts with “spend more on ads” needs checking hard against your actual numbers.
So what should the website do?
Less than you’d think, and it should be cheap.
Load fast, work on a phone, show the Gas Safe number. That’s most of it. Registration at around £310 a year is legally required and that number is the single most important thing on the page.
Have a landlord page. Certificates, turnaround, how you handle portfolios and tenant access. That’s where the money is and almost no gas engineer has one.
Capture the customer, not just the job. Name, address, boiler make, date. That list is worth more than the website that collected it.
Then pair it with reminders. The website brings the customer in once. The reminder brings them back every year after that. Together they turn a £125 job into £1,250 over a decade, and that’s where a gas engineer’s money actually is.
What we’d actually build
Four or five pages, and no more.
A homepage that loads in about a second and puts your number, your Gas Safe registration and your service area in the first screen. A services page covering boiler servicing, repairs, installs and appliance work with guide prices. A landlord page — the one that matters — covering certificates, turnaround time, portfolio handling and how you deal with access. A short about page with your face on it, because gas engineers get let into people’s homes and that matters more than it does for a scaffolder.
Then the part that isn’t really web design at all: every customer who comes through gets recorded properly, with the boiler and the date, so the reminder can go out next year automatically.
Fast site, serious system behind it. For your trade that’s the combination that pays.
The mistakes we see most on gas engineers’ sites
Buying a builder’s website. A £2,500 one-off build with no customer capture behind it is the wrong shape for your trade — you want a fast site plus a system that brings people back, for a fraction of that.
No record of who you’ve serviced. This is the expensive one. Every boiler you’ve ever touched is a customer you could contact and most gas engineers have no usable list at all.
Nothing aimed at landlords. Certificates are the most reliable recurring income in your trade and almost no gas engineer has a page addressing the people who need them in volume.
Marketing hardest in December. You’re already full. The spend does nothing except win work you then have to turn down or rush.
Competing on being cheapest. At your job values there’s no room underneath you. Compete on turning up when you said you would — it’s rarer than it should be and people pay for it.
What’s your customer base worth?
Boilers serviced to date 300 · annual service £125 · currently rebooking 45%
You’re rebooking 135. The other 165 are worth £20,625 a year.
Every enquiry lands in Gaffer
Every service logs against the property with boiler details and next date. Reminders fire on their own ahead of the busy season. Landlord certificates generate and send the same day. Recurring invoicing handles the annual work.
For your trade this matters far more than what the homepage looks like.
Questions gas engineers ask
Which package should I be on?
Most gas engineers do best on Noticed at £49 — website, landlord page, reviews and the reminder system together. That’s £588 a year against an average job of £255, so it needs a little over two extra jobs to break even and everything after that is profit.
I’m rushed off my feet in winter anyway.
Which is exactly why summer matters. Reminders spread the servicing across the year instead of cramming it into three months you can’t physically cover.
Landlords are hassle.
Some are. The good letting agents are the most reliable work in the trade — predictable, repeatable, and they pay to terms.
My customers know where I am.
Some do. The ones who’ve moved, changed their number, or had a boiler fitted by someone else don’t. That’s your 55%.
Is a website really worth it at my job values?
Two extra services a year covers Seen entirely. Most gas engineers we work with get considerably more than that in the first month, because right now they’re invisible to anyone who doesn’t already have their number.
