Do I need a boiler service?

A gas boiler service is as important as an MOT for your car and can have some major benefits:

  • Increased boiler efficiency
  • Reduces the risk of carbon monoxide poisoning
  • Maintains the guarantee of the boiler
  • increases reliability and lifespan of the boiler
  • Planned services are more convenient than an expensive emergency repair
  • Planned servicing saves you money and keeps you warm


I am a landlord, do I need to service my boiler in my rental?

Yes! Landlords are legally responsible for servicing any gas appliances with the frequency required by the manufacturer. It’s also in your interest – a regularly-serviced boiler will break down less and save you money in the long run. Additionally, you must also have a yearly gas safety check which we can complete for an extra £10 +VAT.

James Peterson

I had a boiler service which went exceptionally. The member staff on the phone were very friendly and helpful in explaining what was going to be carried out on the boiler and the benefits of the service.

I Highly recommend this company if you’re looking for a plumber

William Lyford

“We thought it was about time to get our boiler serviced, we found synergI online via Facebook, a quick and simple booking process and friendly phone manor from Amena had us booked in at the end of the month.
The plumber arrived on time & cracked on he noticed something in our boiler that should have been removed when first installed and sorted it there and then which I was very happy about. Great service , professional and reasonably priced for our area, will be using them again…when needed :)”
