Reliable and professional service

We've used Custom Heat for our boiler service for a few years and have always been quite happy with the service. They recently replaced our very old boiler when it broke and did a fantastic job! We live in quite an old house that threw up a number of challenges but our engineer coped with everything brilliantly and did an amazing job of updating our heating system! Would definitely recommend.


Quick and efficient service

Quick and efficient service, very pleased with the work. Our engineer was very knowledgeable and explained clearly and concisely the work he had carried out and why.

Dawn Maria Loughnane


Excellent, easy to book, arrived on time, impeccable manners, very capable & confident. We'll never use anyone else again, both engineers are a real credit to you. Thank you


Top notch job

Top notch job, I commissioned an entire boiler heating system replacement and the first 2 days they were a man short for the job due to many reasons but one man did the job of two to make up for it. What a trooper!


Central Heating Update

Old central heating system updated by installation of combi boiler. Old hot water cylinder and boiler removed, new boiler installed and pipework revised. Work done neatly and efficiently with less disruption than I expected.

Excellent service, aftercare and craftsmanship

Excellent boiler installation last year, the team are always there to help, and responses to queries are quick. It's the aftercare and workmen standards that keep us using Custom Heat.
