A BROKEN BOILER IN WINTER IS NOT A SLOW EMERGENCY
No heat, no hot water, ice-cold radiators, freezing baths — when a boiler fails in the middle of winter, the household stops working. Vulnerable family members are at risk. Pipes can freeze and burst. Mould starts growing in damp rooms within days. A broken boiler is the most disruptive heating emergency a Redhill household can face.
DCD’s Gas Safe engineers carry common spares for every major brand on the van — PCBs, pumps, fans, gas valves, diverter valves, expansion vessels. Most Redhill boiler breakdowns are repaired in a single visit. We diagnose with a combustion analyser before quoting, so you pay for the actual fault, not a guess.

COMMON BOILER FAULTS WE REPAIR FIRST VISIT
LOSING PRESSURE
Boiler keeps needing topping up — usually a small leak in the system, a failed expansion vessel, or a faulty PRV.
ERROR CODES
EA, F1, A06, F22 — every code points to a specific component. We carry the common parts for every major brand.
NO HOT WATER
Heating works but hot water doesn't — usually the diverter valve, not the boiler itself. Quick repair in most cases.
BOILER LOCKING OUT
Boiler keeps shutting down and needs resetting — often the flame sensor, fan, or igniter.
WATER LEAKING
Water visible underneath the boiler — could be the PRV, the heat exchanger, or a failed seal.
NOISY BOILER
Banging, kettling, whistling — usually limescale on the heat exchanger or air in the system.

WHAT Redhill SAYS AFTER A BOILER REPAIR
Frances K. — Redhill
Worcester boiler showing EA fault on a Sunday morning. DCD was here in 70 minutes, knew the code meant a failed flame ionisation electrode, had the part on the van, repaired in 45 minutes. Outstanding service.
Gareth N. — Redhill
Vaillant ecoTEC kept losing pressure. Two other firms said we needed a new expansion vessel — quotes around £400. DCD found the actual leak was on a heating valve in the airing cupboard. £85 part, properly repaired.
Hayley T. — Redhill
Combi boiler making banging noises and the hot water was inconsistent. Engineer ran a magnetic filter check, found the system was full of sludge, recommended a power flush. Boiler runs silently and hot water is consistent now.
Ian B. — Redhill
Boiler kept locking out with F1 code overnight. DCD diagnosed a faulty fan, replaced it within an hour of arriving, also spotted the flue cap was loose and corrected that too. Thorough work.

BOILER REPAIR FAQS
MY BOILER WON'T FIRE UP — IS IT WORTH CALLING?
Yes, always — most non-firing boilers are repaired by replacing a single component (igniter, gas valve, PCB, fan, or PRV). Replacement boilers cost £2,000–£3,500. Repairs typically cost £150–£350. We’ll always tell you honestly if a repair makes sense or if replacement really is the better economic choice.
