Should I service my gas boiler every year?

Yes – Having your gas boiler serviced annually by a gas safe registered engineer is crucial for safety and efficiency.

Getting your boiler serviced in autumn or summer will help ensure it’s in the best possible condition for winter. Regular boiler checks will also make sure it’s working safely, as it’ll be tested for any risk of carbon monoxide poisoning.— MoneySupermarket.com

  • Safe and Compliant – We check for carbon monoxide risks related to flue systems and provide the legally required safety certificate.
  • Insurance Risks – Home insurance policies may require that you have your boiler checked annually to maintain cover according to a recent article (Read the full article here)
  • Reduce Home Energy Costs – A well maintained boiler runs more efficiently, lowering your home energy bills.
  • Helps to Prevent Costly Repairs – Regular servicing catches minor issues early, saving you from emergency breakdown costs.
  • Protect Your Warranty – Most boiler manufacturers require annual servicing to keep warranties valid. Not maintaining your boiler may result in a breakdown within the warranty period not being covered resulting in unexpected costs to you as the homeowner.
  • Reduce Your Carbon Emissions – Efficient performance means a greener home and smaller carbon footprint.

Key Reasons to Service Your Gas Boiler

Lower Gas Bill

During a service, we will ensure that your boiler runs as efficiently as possible. This will mean it requires less gas to heat your home, lowering your monthly gas bill and carbon emissions.

Prevent Costly Repairs

Our gas engineers can identify and diagnose minor faults with your boiler before they cause it to stop working correctly. This can save you a significant amount by avoiding costly emergency callouts for boiler repairs.

Prevent & Identify Boiler Leaks

Carbon Monoxide leaks can be fatal and should be avoided at all costs. With an annual service carried out by a Gas Safe registered engineer, you can be sure that your boiler is safe!

Common Boiler Servicing FAQs

Our boiler service costs £105+VAT. Which includes a full service and certificate for one appliance.

If your boiler requires any routine maintenance such as new door seals or gaskets for example, this will be explained to you at the time and a cost provided for the additional works. If you’re happy with the additional cost and want to go ahead with the work we often have the parts in stock and the engineer can complete the job there and then, easy!

Servicing a boiler usually takes one of our gas engineers around 1 hour to complete, but it can take longer depending on the specific make and model.

Stripping down heat exchangers during a four year major service can take longer and incur some additional labour costs as a result but this will be explained at the time and you can choose the option that fits your budget.

(keeping up with scheduled maintenance is essential for warranty on new appliances as well as reliable operation and safety of older appliances. We would always recommend that you follow the manufacturer’s guidance on this matter.)

We can service all makes, models and types of boilers.

We can also service commercial boiler models, air conditioning, heat pumps, electric boiler models and unvented hot water systems.

For more information on all of our services, please see the services page for more information.

Used Thermatek for second year for annual boiler service having used them before. Booked a time slot and with reminders in the run up great efficient and polite service. Reliable company and would recommend. Pricing fair for annual gas boiler check and won’t go anywhere else now I’ve found Ryan and his team.

Ryan literally saved me from a total nervous breakdown. He came onsite to sort out a leak that was flooding the flat below us and the basement. We couldn’t get anyone to help us, agents, plumbers and our boiler manufacturer. I woke him at 8 am and he was onsite doing the repairs necessary by 10am. Couldn’t have asked for more help. Bill was reasonable, and we are now engaging his company to install a new heating system . Ryan was knowledgable and communication was excellent . Couldn’t recommend Ryan’s business more

Was recommended Thermatek by a family member. Required gas hob removed and sink and washing machine taken out in preparation for new kitchen installation. Job was easy to organise at time I wanted it done. Engineer turned up on time. He explained as he went along and all tasks were completed promptly and efficiently. Engineer was very friendly and easy to talk to. Coming back to reconnect washing machine and fit new sink. Wouldn’t hesitate to recommend company.

I had previously always used a different, well known Edinburgh company, for all boiler related servicing and work. When it came to fitting a new boiler, the other company seemed unwilling to relocate the boiler into the attic, nor to deal with a system that included an area of underfloor heating, and gave me a very high quote. When Ryan from Thermatek came to take a look, he was really easy to speak with, said the necessary work could be done no problem and gave me a reasonable quote as well as financing info. He was helpful in arranging fitting dates to work around our needs. Two members of his team have subsequently fit a new boiler for us. They were nice guys, lovely to speak with, were professional and left everything clean and tidy. I really couldn’t have asked for better service and will be using Thermatek going forward for the annual boiler servicing.

Thermatek replaced the cover of my gas meter after my one cracked and was no longer water tight. Service was prompt and friendly.
