A proper full boiler service that keeps your warranty valid, your gas bill lower, and your boiler running for years longer.
Last year's "service" was 12 minutes and a sticker on the casing.
Worried your manufacturer warranty has been voided by a missed service.
Boiler making strange noises but technically still working.
Gas bill creeping up year on year for no obvious reason.
We listen to the symptoms, inspect the system on-site and explain what's actually wrong — in plain English, not jargon.
Before we lift a spanner, you get a clear written price. No hidden charges, no surprise add-ons at the end.
Most jobs slot in within the same week — emergencies covered same-day, 24/7 across Surrey.
Dust sheets down, boots off, all gas work signed off to current Gas Safe regulations. Your home left cleaner than we found it.
You get a full service checklist with readings (flue gas analysis, gas rate, working pressure, case seal) — emailed the same day for your records and warranty file.
Full strip-down of the burner and combustion chamber, electrode gap check, flue gas analysis (CO/CO₂ ratio), gas rate measurement, case seal integrity test.
Every Viessmann (and other major brand) warranty requires annual servicing by a Gas Safe engineer with documented evidence. We provide both.
Hairline cracks on heat exchangers, weeping PRVs and tired expansion vessels are 10x cheaper to fix in summer than during a January no-heat callout.
Cleaning the burner, condensate trap and heat exchanger typically restores 5–10% efficiency on a 5-year-old boiler — straight off your gas bill.
A proper service takes time. We block 90 minutes — not 15 — so every checkpoint is actually performed and logged.
Combine your service with a Gas Safety Certificate for landlords at a discounted bundle rate.
Book any boiler repair this month and we'll include our 21-point health check at no extra cost.
A genuine service per manufacturer guidelines covers: visual inspection, casing removal, burner clean, heat exchanger inspection, condensate trap clean, flue integrity check, flue gas analysis to BS 7967, gas tightness test, working pressure check, expansion vessel charge, safety device test, case re-seal.
A serviced boiler runs 8–12% more efficiently than a neglected one. On an average Surrey gas bill that's £120–£200/year. The service pays for itself — and you avoid the panic-buy emergency repair.
Late summer/early autumn (Aug–Oct) is ideal. Engineers have availability, parts are in stock, and any issues found are fixed before the boiler is needed in earnest. Don't wait until November when everyone's calling.
Same trusted engineer, same fixed pricing — wherever you are in our coverage area.
Local. Gas Safe. Available 24/7. Get a fast, no-obligation quote — most enquiries answered the same day.
