BOILER SERVICING
A Little Maintenance Now Could Save You Trouble Later
Your boiler works hard to keep your home warm and your hot water running. But like any appliance, it needs looking after.
An annual boiler service can help identify potential problems before they turn into bigger, more expensive repairs. It also helps make sure your boiler is operating safely and efficiently.
Whether your boiler is relatively new or has been keeping your home warm for years, regular servicing is one of the simplest ways to look after it.
Why Have Your Boiler Serviced?
Keep Your Home Safe
A boiler service includes important safety checks to help identify potential issues with your appliance.
Catch Problems Early
Small faults aren’t always obvious. Regular servicing gives you a chance to spot potential problems before they become more serious.
Look After Your Boiler
Keeping up with maintenance can help your boiler continue working efficiently and may help extend its working life.
Protect Your Warranty
Many boiler manufacturers require annual servicing to maintain warranty cover. Check the terms of your particular warranty.
WHAT TO EXPECT
Straightforward Boiler Servicing, Without the Fuss
You shouldn’t need to worry about what’s involved in getting your boiler serviced.
Dave will inspect your boiler, carry out the appropriate checks and let you know if anything needs attention.
A typical boiler service may include:
- Checking the boiler's general condition
- Inspecting key components and safety devices
- Checking combustion and flue performance, where applicable
- Looking for leaks, faults or signs of wear
- Carrying out checks in line with the manufacturer's instructions
If Dave spots something that needs repairing, he’ll explain the issue and talk you through your options before any additional work is carried out.

Boiler Playing Up? Let's Find Out What's Wrong.
No heating? No hot water? Strange noises coming from your boiler?
When something goes wrong, you want to know what the problem is and what it’ll take to fix it.
Dave can investigate boiler faults, explain what he finds and advise you on the next steps. Where a repair is possible and worthwhile, he’ll help you get your heating working again.
Common Boiler Problems
No Heating or Hot Water
If your boiler isn’t providing the warmth or hot water you need, it’s time to find out why.
Low Boiler Pressure
Pressure problems can affect how your heating works and may point to an underlying issue.
Strange Noises from boiler
Banging, whistling or gurgling noises can be signs that something isn’t working as it should.
Boiler Keeps Switching Off
If your boiler regularly shuts down or displays fault codes, it may need professional attention.
Leaks or Drips from boiler
Water leaking from your boiler or its associated pipework shouldn’t be ignored.
Radiators Not Heating Properly
Cold or unevenly heated radiators could indicate a problem within your heating system.
HONEST ADVICE
Repair or Replace?
Dave Will Help You Decide.
Not every boiler problem means you need a new boiler.
Sometimes a repair is all that’s needed to get things working again. Other times, particularly with older boilers or repeated faults, replacing it may be the more sensible option.
Dave will explain what he’s found, discuss the available options and help you understand whether repairing or replacing your boiler makes more sense.
The aim is to help you make the right decision for your home and budget, without unnecessary pressure.
