Professional boiler servicing in Harrow
A boiler service is a planned safety and performance check, not a repair visit. Harrow Heating checks the appliance, flue, ventilation, controls and key safety functions so small issues can be spotted before they become inconvenient or expensive.
Most manufacturers expect an annual Gas Safe boiler service to maintain warranty cover. Keeping a clear service record also helps when selling, renting or managing a property.

Thorough service and friendly engineer
They are a company you can trust. They are quick at coming to sort a problem out. My recent experience of two engineers couldn't be better, I felt safe after they left.They were both polite,friendly gave full explanation of work carried out, both what I call "old school engineers", an asset to Harrow Heating. - Martin Devine

Harrow Heating top notch
The engineer arrived well within the allocated time scale. He checked the location of the jobs and got on with the installation of the new boiler. I find Harrow Heating trustworthy and efficient.

Great Service
More than usual the engineer was friendly, straightforward, thorough and clearly very skilled and experienced at his job. Used Harrow Heating for few years, always find them reliable, knowledgeable and value for money. Engineers are highly competent and explain everything, feel safe, our boiler is kept in top condition. - claire

Highly recommend
Following an annual service from Harrow Heating, a couple of faults with my boiler were identified. A second visit was scheduled just 2 days later to resolve the issues. The engineer was polite and professional, explained the work that was necessary and was finished within the hour. Highly satisfied with the service. - Carol
