Five reasons to book a boiler repair now
Don't wait for a complete breakdown. These signs mean your boiler needs attention from a registered engineer.
Strange smells or sounds
A burning smell, popping noises or loud kettling are warning signs. Stop using the boiler and get it checked; these can mean carbon monoxide or a serious fault.
Losing pressure constantly
If you're topping up the system pressure more than once a month, there's a leak somewhere—inside the boiler or the pipes. We find it and fix it before it damages the system.
The boiler won't stay lit
Ignition problems or a boiler that cuts out after a few minutes often point to a faulty thermostat, a sensor issue or a clogged flue.
It's been longer than a year since service
Most manufacturers expect an annual service to keep the warranty valid. A yearly check-up stops small issues becoming emergencies and keeps your system efficient.
Water pooling around the base
Damp underneath the boiler usually means a leak from an internal pipe or valve. It needs fixing soon to prevent corrosion and inefficiency.
Carbon monoxide warning: Headaches, dizziness, nausea or chest pain near the boiler can signal dangerous CO leaks. Turn the boiler off, open windows, leave the building and call the National Gas Emergency Service on 0800 111 999.

Why repair quotes vary
A service is a fixed job. Repairs depend on what's wrong and what parts need replacing. We always diagnose first and quote before we start.
The part that's failed
A thermostat, sensor or valve costs less to replace than a heat exchanger or gas valve, and some parts are simply more expensive to source.
Labour time
A quick fix takes 30 minutes. Faults deep inside the boiler or that need the case opened take longer.
Age and parts availability
An old boiler might need spares ordered from the manufacturer, which takes a day or two longer.
Whether it's still worth repairing
If a boiler is over 10 years old and the repair costs half the price of a new one, we'll tell you that upfront.
Keeping your boiler running smoothly
After a service or repair, a few simple checks help you spot the next problem early and keep everything running well.
- Book next year's service now. Many people forget after a year's passed; a quick call in advance keeps you on track.
- Watch the pressure gauge. If it creeps up above 1.5 bar or drops below 1 bar between services, let us know.
- Listen for changes. A new rumble, whistle or rattle is worth mentioning at the next service; we'll investigate.
- Keep the boiler area clear. Don't block air vents or store things directly against the unit.
- Test your CO alarm monthly. If you have one, press the test button and replace batteries annually.
- Run the heating briefly in summer. A few minutes every month keeps pumps and valves from seizing during the off-season.
Boiler service and repair FAQs
Still unsure? Call 01225 123456 and we'll answer any questions about your boiler or heating system.
How often should I have my boiler serviced?
Once a year. Most boiler manufacturers require an annual service to keep the warranty valid. If your boiler is over 10 years old or you've had a repair, annual servicing helps catch the next fault early and keeps everything efficient.
How much does a boiler service cost?
We give fixed prices for a standard service; you won't find any hidden charges. The price depends on the boiler type and your location within our service areas. Call us or use the quote form for an exact figure.
What do you do if you find a fault during the service?
We tell you what it is, explain what it means, and quote the repair cost. You decide whether to go ahead there and then, or book it in later. We never start work without your say-so.
Do you fix boilers that are no longer under warranty?
Yes. We repair all makes and models, whether they're under warranty or not. If a repair doesn't make sense on an old boiler, we'll tell you straight and suggest a replacement instead.
Can you come out same day if my boiler breaks?
Yes. We run a 24/7 emergency service with no callout charge. Call {phone} anytime and we'll get an engineer to you the same day where possible. In winter, demand is high, so call straight away.
What's the difference between a service and a repair?
A service is a scheduled annual inspection and health check of a working boiler; we test everything and issue a certificate. A repair is when something has gone wrong. We diagnose the fault, tell you the cost, and fix it if you ask us to.
