Benefits Of A Boiler Service
Save Money On Fuel Bills
A well-maintained boiler operates more efficiently, helping you save money on your fuel bills throughout the year.
During our full boiler service, we’ll check your boiler’s gas pressure and conduct a flue gas analysis to ensure it’s functioning at peak efficiency.
We’ll also clean essential components such as the heat exchanger and burners, which can often become less efficient over time, leading to unnecessary increases in your energy costs.
Keep Your Boiler Safe
The safety of your boiler should never be taken lightly.
We check for gas leaks, analyse flue gases to ensure safe combustion, and inspect all key components for any signs of wear or damage.
We also clean the condensate trap and test your boiler’s pressure, providing you with peace of mind that your heating system is operating safely and efficiently.
Spot Boiler Problems Early
Regular boiler servicing offers much more than just safety checks — it’s a proactive approach to identifying potential issues before they escalate into major problems.
During our detailed inspection, we’ll analyse flue gases, check pressures, and inspect critical components for wear and tear.
Additionally, we’ll clean your magnetic filter and test your water quality (full service only), helping to spot early warning signs that could save you from costly emergency repairs in the future.

The 2 Types Of Boiler Service
Standard Boiler Service
To ensure optimal performance and safety, a standard boiler service from Thames Boilers includes comprehensive checks and essential maintenance procedures.
We ensure your boiler operates efficiently and safely with our extensive service, which includes:
– Detailed analysis of flue gases and checks on gas pressure,
– Thorough inspection of visible flue components and internal parts,
– Professional cleaning of your condensate trap and magnetic filter.
Additionally, we provide you with a digital service record and certificate for your peace of mind.
Full Boiler Service
Many modern boilers require a more comprehensive inspection periodically (usually every 2-3 years), which is why we offer a full boiler service that extends beyond our standard maintenance package.
Our full service includes everything in the standard package, plus these essential extras:
– Thorough cleaning of burners and heat exchanger components,
– Replacement of critical gaskets and seals as necessary,
– Extensive water quality testing and radiator performance checks.
We will also provide detailed recommendations for any additional maintenance your system might require.

Frequently Asked Questions About Boiler Servicing
My boiler has a fault – should I book a service?
No.
If your boiler isn’t working properly, it’s advisable to book a repair instead of a service. This is because a service is a maintenance check that won’t rectify existing faults, and any repairs needed would incur additional costs.
Save your annual service for when your boiler is operating normally.
If my boiler develops a fault after a service, do I have to pay for another visit?
Yes, you’d need to cover the cost of any repairs required following a boiler service.
As outlined in our terms, a service ensures that your boiler is operating safely and efficiently, but it isn’t a guarantee against future faults.
It’s similar to a car MOT: passing it today doesn’t prevent issues from arising later, and any necessary repairs would require a separate appointment and payment.
Are You Gas Safe Registered?
Yes, Thames Boilers is fully Gas Safe registered, which legally permits us to work on gas appliances in the UK.
