 Trustindex verifies that the original source of the review is Google. We have used IHC for many years to service or main church boiler and have always been happy with their service. Recently, we had the need for a new boiler for the heating and hot water in another part of the church. IHC provided a very competitive quote and carried out the work in a timely and efficient manner. The engineers were polite and tidied up after themselves. The communication was clear throughout the process and we will continue to use them and any additional services we may require.
