Common boiler faults and breakdowns we fix

A boiler that stops working is never convenient, especially when it leaves you without heating or hot water. Our Newcastle heating engineers repair all the common faults day in, day out, so we can usually spot the cause quickly. We carry the parts that fail most often in the van, which means the majority of repairs are finished on the first visit.

No heating or no hot water

If your boiler won't fire up at all, the cause can range from a faulty thermostat or diverter valve to a problem with the pump or printed circuit board. We test each part in turn to find the real fault rather than simply replacing components and hoping.

Leaks and dripping pipes

Water pooling under the boiler, or a dripping pressure-relief pipe outside, usually points to a worn seal, a corroded part or pressure that's too high. A leak won't fix itself and can cause further damage, so it's worth having it traced and sealed sooner rather than later.

Low or dropping pressure

If the pressure gauge keeps falling below the normal range, your heating may feel weak or cut out. Low pressure is often caused by a small leak somewhere in the system or a failed expansion vessel. We find the reason it's losing pressure and put it right, rather than just topping it up.

Pilot light and ignition problems

A pilot light that keeps going out, or a boiler that clicks but won't light, can be down to a faulty thermocouple, a gas-supply issue or a blocked jet. These are gas faults, so they should always be handled by a Gas Safe registered engineer.

Banging, gurgling or whistling noises

Strange noises often mean trapped air, a failing pump or a build-up of sludge and limescale inside the system — sometimes called kettling. We diagnose the source and, where sludge is the culprit, advise on clearing the system so the noise doesn't come back.

Fault and error codes

Modern boilers show an error code on the display when something's wrong. That code is a useful clue, but it rarely tells the whole story. We read the code, then carry out proper checks to confirm the fault before fitting any parts.

Cold radiators

If radiators stay cold, heat up slowly or are warm at the top and cold at the bottom, the issue may be trapped air, a stuck valve or sludge sitting in the system. We'll find out why and get your radiators heating evenly again.

What to do first when your boiler breaks down

Before you call anyone out, a few quick checks are worth a try. Make sure the boiler has power and the gas supply is on, and check that other gas appliances are working. Look at the pressure gauge — if it's very low, your manual will show how to top it up safely. Check the thermostat is set correctly and the timer hasn't slipped, and if there's an error code on the display, make a note of it to pass on to us.

If you ever smell gas, don't turn anything electrical on or off. Turn the gas off at the meter, open the windows and call the national gas emergency line on 0800 111 999 straight away. For a non-urgent repair, send us the details through the form or email info@heatingengineernewcastle.co.uk and we'll arrange a visit.

Should you repair or replace your boiler?

This is one of the most common questions we're asked, and the honest answer depends on your boiler. If it's fairly modern and the fault is minor, a repair is almost always the sensible, cost-effective choice. If the boiler is older, breaks down repeatedly, or the parts are hard to source, the repair bills can start to add up to more than a new boiler would cost over its lifetime.

Where a boiler is beyond economical repair, we'll say so plainly and talk through your replacement options — no pressure and no hard sell. The decision is always yours, and we'll give you the facts you need to make it.

How quickly can we get your heating back on?

We know a cold home can't wait, so we aim to attend as quickly as possible, often the same or the next day across Newcastle. Because we carry the most common spare parts with us, most repairs are completed there and then. If a part needs ordering, we'll let you know the timescale upfront and do our best to get your heating working again fast.

What affects the cost of a boiler repair

Every repair is different, so rather than guess at a price we explain what it depends on. The main factors are the fault itself, how long it takes to put right and whether any parts are needed. A simple adjustment costs far less than replacing a major component such as a pump or heat exchanger. The age and make of your boiler can also affect how easily parts are sourced.

Whatever the job, we'll diagnose the fault, explain it in plain terms and give you a clear price before any work begins. You'll always know where you stand, so there are no surprises when the work is done.

Boiler Repair FAQs

We aim to attend as quickly as we can, often the same or next day across Newcastle. As we carry common parts with us, most repairs are completed on the first visit. If a part has to be ordered, we'll tell you how long it will take before we go ahead.

If your boiler is fairly modern and the fault is minor, a repair is usually the better value. For older boilers that break down often or are beyond economical repair, we'll give you honest advice on whether a new, more efficient boiler would save you money in the long run.

Yes. Our Gas Safe engineers repair all the major makes and models, including Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Potterton and more. If you're unsure of yours, just tell us the make and model when you get in touch.

It depends on the fault and whether any parts are needed. We always diagnose the problem first and give you a clear, upfront price before carrying out any work, so you're never left guessing and there are no surprises at the end.

Pressure that keeps dropping usually points to a small leak somewhere in the system or a failed expansion vessel. Topping it up is only a short-term fix. We'll find the real cause and put it right so the pressure holds steady.

For most minor faults, yes. But if you smell gas, see signs of a leak, or the boiler is making loud or unusual noises, switch it off and leave it off until we've looked at it. If you suspect a gas leak, turn the gas off at the meter and call the national gas emergency line on 0800 111 999.
