 FAQ – Boiler Service Harrow

How much does a boiler service cost in Harrow?
Our fixed price is £89, regardless of your location within Harrow.

Do you service all types of boilers?
Yes — we work with combi, system, and regular boilers from all major manufacturers.

Do you repair boilers as well?
Yes. If our engineer finds a problem during the service, they can advise on the repair options.

How long does the service take?
Most services take 30–60 minutes, depending on your boiler’s condition.

Why should I have my boiler serviced?

It is recommended to keep your unit in good health to lessen the likelihood of loss of heating and hot water, but also to help keep other dangers, like leaking poisonous gasses, at bay. A good working boiler will also ensure you are not wasting valuable energy and money.

How can I tell if my boiler has any problems?

A failing boiler isn’t always an easy thing to spot, but you can keep an eye out for a few signs. The most common is the loss of heated water, and no central heating. Another helpful indicator is the colour of your boiler flame. A healthy boiler flame should be blue. If you have a yellow or orange flame, then this is a clear sign your boiler needs a health check.

Why call Efficient Home Energy?

As professionals, our main priority is to keep you safe. We have years of experience working with boilers, and we will always be able to advise you on the best course of action. We’ll make sure you have a safe and functioning boiler.

I was really impressed with the team at Efficient Home Energy. Having had a number of negative experiences with British Gas (one of which included them damaging our boiler!) and having to wait 3+ months for another service appointment I decided to give Efficient Home a go. I’m so glad I did! Not only was I able to book an engineer to visit 2 days later, but Huseyin was incredibly professional and efficient. Having felt very stressed during our last British Gas appointments, Huseyin was such a calm presence and able to complete our survey very quickly. We have small children at home and getting someone to visit quickly to check for safety was very important, but more than that you want to feel reassured with the person doing those checks! I will definitely work with the team again.

I reached out to request both an EICR and a Gas Safety Certificate, and was so pleased to receive both reports within 24 hours. The efficiency was incredible, and the service was not only fast but also exceptionally polite and professional. It was an absolute pleasure to deal with them. Highly recommended!
