No heat? No hot water? Pressure dropping? Fixed-price repairs by a Gas Safe engineer — usually back on by tonight.
Boiler locked out with an F-code you can't decipher.
Pressure keeps dropping back to zero every few days.
Radiators warm at the bottom, freezing at the top.
Hot water cuts out 30 seconds into a shower.
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.
Workmanship guaranteed in writing. One number to call if anything ever needs revisiting — Callum picks up.
One transparent diagnostic charge — then a written fixed price for the repair before we touch a screw. No open-ended hourly billing.
We carry common parts for Viessmann and other major brands in the van — diverter valves, PCBs, pumps, expansion vessels, ignition leads.
If your 14-year-old boiler will cost £600 to repair and die again next winter, we'll tell you straight — not stack repairs on a dying unit.
On call 24/7 across Surrey. Most no-heat calls answered within 2 hours during working day, same evening for out-of-hours.
Up-to-date training on the brands we work with — including the latest control board firmware quirks the YouTube guides miss.
Every repair backed in writing. If the same fault returns within 12 months, we come back at no charge.
Book any boiler repair this month and we'll include our 21-point health check at no extra cost.
Low-pressure fault codes on a Viessmann are almost always a slow leak, expansion vessel failure or a dripping PRV. Pump and pressure sensor faults are also common across most makes. We don't just clear codes — we fix the root cause so it doesn't come back in 3 weeks.
Rule of thumb: if your boiler is over 10 years old AND the repair quote exceeds 50% of a new install, replacement is usually the better call. We model both options on paper so you can see the 5-year cost — not just the cheaper today.
Three causes account for 90% of slow pressure drops: a weeping PRV (look for water at the discharge pipe outside), a failed expansion vessel (we re-pressurise and test), or a hidden leak under floorboards. We work through them in cost order, not guess order.
Same trusted engineer, same fixed pricing — wherever you are in our coverage area.
