Ralf travels directly to your London address. No call centre, no sub-contractors. The engineer who answers the call is the engineer who arrives at your door.
Ralf carries out a thorough fault diagnosis before touching anything. No guesswork, no unnecessary part replacement. You are told exactly what the fault is and what it will cost to fix before any work begins.
We carry the most commonly required spare parts on the van. The majority of emergency boiler repairs are completed on the first visit. Where a part must be ordered, we make the property safe and return as soon as it arrives.
Ralf has diagnosed and repaired all of these faults across London, on every major boiler brand.
The boiler attempts to light but fails to ignite. Common causes include a faulty ignition electrode, dirty or cracked electrode, weak spark, or gas supply interruption. Usually repaired on the first visit.
Sludge, limescale, or magnetite build-up blocks the heat exchanger, causing overheating and lockout. Often accompanied by kettling or banging noises. A power flush may be required after repair.
On combi boilers, a failed diverter valve causes the boiler to produce hot water but no heating, or heating but no hot water. Replacement is a common repair on Vaillant and Worcester Bosch combis.
A seized or failing pump prevents hot water from circulating around the system. Symptoms include radiators not heating evenly, the boiler cycling on and off, or error codes related to flow rate.
A faulty PRV can cause the boiler to lose pressure repeatedly or drip water from the overflow pipe. Requires replacement to restore safe operation and maintain correct system pressure.
The printed circuit board controls all boiler functions. A failed PCB typically produces multiple fault codes or causes the boiler to behave erratically. Replacement restores full operation.
In cold weather, the condensate pipe from a condensing boiler can freeze and block, causing the boiler to lock out. Ralf can thaw the pipe and insulate it to prevent recurrence.
On older boilers with a pilot light, a failed thermocouple causes the pilot light to go out repeatedly. Replacement is straightforward and typically completed on the first visit.
Ralf has hands-on experience with every major brand installed in London homes. No unfamiliar boilers, no guesswork.
We regularly repair both the ecoFIT pure and ecoTEC ranges. Common faults include F22 (pressure loss), F75 (pump or pressure sensor), and diverter valve failures on combi models. Vaillant parts are carried on the van.
Worcester Bosch Greenstar boilers frequently develop E9 overheat errors, thermistor faults, and pump failures on older units. We carry the most common Worcester Bosch spares for same-day repair.
The Ideal Logic Plus and Vogue ranges commonly develop PCB faults, ignition failures, and fan issues over time. Ralf is experienced with both the older Classic range and the current Logic+ models.
Baxi boilers frequently display E1 and E2 fault codes related to ignition failures and overheat thermostat trips. We also see diverter valve and pump failures on the 200 and 400 Combi series.
Older Potterton models commonly develop heat exchanger blockages, faulty gas valves, and ignition electrode failure. Parts availability for discontinued Potterton models is confirmed before any work begins.
We also repair Glow-worm, Ariston, Ferroli, and other brands found in London properties. If you are unsure whether we cover your boiler, call 07472 251465 and Ralf will confirm.
