"Came out at 8am on a Saturday when our combi packed up in the middle of half-term. Fixed it in under an hour. Charged what he quoted on the phone. Boiler's been fine ever since."
Annual servicing, breakdown repairs and full boiler installations by engineers who live locally and answer their phone. Fixed prices, honest diagnostics, no call-out fee inside SA1–SA9.
Every job is quoted upfront. If we can't fix it the same day, you don't pay for the return trip. Parts carry a 12‑month warranty and every service ends with a written report. See all our services →
A full manufacturer-spec service: flue gas analysis, seal check, condensate flush, pressure test and safety report. Keeps your warranty valid and your bills honest. About 45 minutes on site.
No heating, no hot water, F-codes, leaks, low pressure, PCB and pump failures. We stock the common parts for Worcester, Vaillant, Ideal, Baxi and Viessmann in the van — most faults resolved on the first visit.
Combi, system or heat-only replacements with a proper power-flush, magnetic filter and smart control included as standard. Free in-home survey, fixed quote in writing, 10-year Worcester warranty.
Annual Landlord Gas Safety Records for HMOs, single lets and holiday homes across Swansea and Gower. Digital certificate emailed within 24 hours. Bundle with a boiler service for £110 total.
Two vans running Monday to Saturday, based at Weighbridge House in Llansamlet. No call-out fee for SA1–SA9. See all areas we cover →
Both of our engineers were born here and know the housing stock — the Victorian terraces of Brynmill, the newer estates around Waunarlwydd, the salt-air corrosion on Mumbles combis. That local knowledge shows up in the diagnosis.
Just outside SA1–SA9? Ring us — we'll usually still come out for a small fuel surcharge, or recommend someone we trust who's closer.
The same routine whether you're booking a £72 service or a £3,000 install. Everything in writing, everything explained.
A five-minute call — we ask about the boiler make, the fault code if any, and the last time it was serviced. You get a quote or a booking slot before we hang up.
Van stocked with the common parts. Shoe covers on, dust sheets down. We diagnose the fault, quote the fix on the spot, and only proceed once you've said yes to the price.
You get a digital service record, part warranties, and a photo of the flue analyser reading. Payment on completion — card, bank transfer, or cash. No hidden fees.
Verified reviews from Google and Checkatrade. We pick a handful each year that feel most useful to a new customer — not just the five-star ones.

"Had three quotes for a new boiler. This one wasn't the cheapest but the survey was proper — measured radiators, checked the gas supply, actually asked how we lived. Install was tidy, floor was cleaner than when they arrived."
"Landlord for six properties. Been using them for four years for the CP12s. Turn up when they say, digital certs same day, never once tried to sell me a job I didn't need."
If yours isn't here, ring us — a two-minute call usually saves everyone a wasted visit.
