About Us

Gas Safe Registered Business

Optimised Heating are licensed by Gas Safe Register, the only official register of gas engineers. WHY IS THIS IMPORTANT? A recent survey revealed that three out of every five jobs done by unregistered people, without the requisite qualifications or training, are unsafe. So don’t take the risk, trust us instead. It is vital that any gas work you need to complete is carried out by a Gas Safe Registered engineer. Jobs carried out illegally each year by workers that are not on the Gas

Safe Register are putting people’s lives at risk. Optimised Heating adheres to the rules and regulations of the Gas Safe Register, and our Gas Safe Registration Number is 506335.

Optimised Heating is an approved installer with leading boiler and heating manufacturers such as Vaillant, Worcester, and Baxi. As such we are able to offer extended warranties for products such as controls, boilers, and hot water cylinders.
