Common boiler faults we fix in Sunderland

Understanding the most common boiler faults in your area helps you know what to expect. Here are the faults we attend most frequently across Sunderland, along with what usually causes them and how we fix them.

No heating or hot water

Often caused by a faulty diverter valve in combination boilers, common in ageing Baxi and Worcester Bosch units. Can also indicate low pressure, a failed pump, or a faulty motorised valve in traditional systems.

Boiler making banging or kettling sounds

Caused by limescale or sludge build-up on the heat exchanger. Particularly common in Sunderland's older housing stock where systems have never been power flushed.

Boiler pressure keeps dropping

Usually a leak in the system, at a radiator valve, a pipe joint, or internally within the boiler. Can also indicate a failing pressure relief valve.

Boiler keeps cutting out (locking out)

Could be a faulty flame sensor, a blocked condensate pipe, low gas pressure, or an overheating issue caused by a failing pump.

Pilot light keeps going out

On older non-condensing boilers, usually a faulty thermocouple. On modern boilers typically an ignition or gas valve issue.

What our boiler repair service includes

Every repair visit in Sunderland follows the same process. Your Gas Safe engineer runs a full system check, tests gas inlet pressure, inspects the flue and heat exchanger, then gives you a clear diagnosis.

You get a plain English explanation and a fixed price. No jargon, no pressure. If replacement makes more sense than repair, we will tell you, with realistic new boiler costs and no obligation.

Our vans stock parts for Worcester Bosch, Vaillant, Baxi and Ideal, so most repairs in Sunderland are completed in a single visit.

Boiler repair FAQs

Everything you need to know about booking a boiler repair in Sunderland.

How much does boiler repair cost in Sunderland? +
Every boiler repair in Sunderland starts with our fixed-price £89 call-out and diagnosis. If we fix the fault without parts, £89 is all you pay. Where parts are needed, we give you a no-obligation fixed price before ordering. Common repairs range from £120 for a sensor to £300 for a fan. There is no call-out charge on top of the £89 fee.
How quickly can a Gas Safe engineer attend in Sunderland? +
For urgent breakdowns we aim to attend same day or first thing the following morning across Sunderland and the SR1, SR2, SR3, SR4, SR5, SR6, SR7, SR8 postcode areas. Call 0191 540 2051 and we will give you an honest arrival window. We work 7 days a week.
Is it worth repairing my boiler or should I replace it? +
If your boiler is under 8 years old and the repair costs less than half of a new boiler, repair is almost always the better option. Between 8 and 12 years it depends on the fault. Over 12 to 15 years old with a significant fault, replacement usually makes more financial sense, parts availability decreases and a new A-rated boiler cuts energy bills significantly. We always give you an honest recommendation.
Do you cover all parts of Sunderland? +
Yes, we cover every postcode in the Sunderland area including SR1, SR2, SR3, SR4, SR5, SR6, SR7, SR8. We are based locally and know the area well. Whether you are in the town centre or an outlying village, we can attend.

We repair all major brands across Sunderland including Worcester Bosch, Vaillant, Baxi, Ideal, Potterton, Glow-worm, Intergas, Viessmann and Ferroli. Our engineers carry a range of common parts to avoid unnecessary second visits.
What should I do if my boiler breaks down? +
If you smell gas, leave the property immediately and call the National Gas Emergency line on 0800 111 999. For all other faults, call AR Heating and Gas on 0191 540 2051. We will ask a few questions, advise whether it needs immediate attention, and arrange attendance as quickly as possible. Never attempt to repair a gas appliance yourself, always use a Gas Safe registered engineer.
Will I get a fixed price before you start any work? +
Yes, always. Our £89 covers the call-out and diagnosis. If additional parts or labour are required we give you a written fixed price before proceeding. You will never receive a surprise invoice from AR Heating and Gas.
