I have used Heatco for a number of years, for everything from a regular boiler service to a total heating system overhaul. Always reliable, punctual, pleasant, professional and really clued up on all things heating-related.

Replacement of leaking boiler in an old vented system with a Greenstar combi boiler. Heatco we're always on time for each appointment ( note the booking system doesn't send an appointment reminder, so note or screen-shot your time from the booking page ) Joe and Darren worked professionally and efficiently to resolve our heating issues and fit the new system. They were both very pleasant to work with and took time to listen and discuss issues and solutions. When the old boiler gave-up suddenly, changing the urgency of the job, they were able to change plans and complete the job sooner than originally expected.

After having my old meters changed to smart meters, the gas meter failed the tightness test. Engineer could not find the fault. Gas was switched off. I left a message with Heatco and they quickly replied. Next day before 09.00 Darren arrived. He quickly found the fault and repaired straight away. I have always found Heatco to be reliable, efficient and superb when it comes to communication. I would not hesitate to contact them again.

Joe Walley of HeatCo came out to estimate for replacing our failed Combi boiler and within a week his team, Dean (and latterly a second Dean) were on site, stripping out the old equipment and installing a different system which Joe recommended - a Condenser Boiler. Although I had misgivings about switching methods, Joe assured me it would be the best to deliver ample heat and hot water. The work was challenging, due to the very confined location of the old system's flu. It was accomplished with great care and professionalism and works perfectly. I would not hesitate to recommend this company.

HeatCo installed our boiler 10 years ago, and they have visited every year to carry out an annual service. As ever, Joe has been polite, friendly and efficient. I recently recommended HeatCo to a friend who was in need of a new boiler, and he has been very pleased.

We received excellent service from HeatCo, from initial quotation through to the installation of a replacement boiler and some follow-up after installation. Although we were being fitted in after a cancellation, the installation was done to the promised schedule and price despite a change we suggested after the quote had been made. The quality of workmanship was excellent and the customer service was beyond reproach. We would have no hesitation in recommending Joe or his installation engineer, Dean.
