HIU Service

A HIU Service ensures the continued efficiency of your heating system. All manufacturers recommend appliances to be serviced annually. RBG Services offer a 12 month guarantee on all our works.

HIU Repair

We are experienced in working with industry leading models, including SAV Systems, Switch2, Evinox and Wilson, popular amongst developments across London. RBG Services will diagnose and repair your HIU in a professional and efficient manner.

HIU Installation & heating Upgrades

RBG offer various upgrades to your system to improve efficiency. Whether you are looking to install a new HIU or want to control your heating remotely with a Smart Thermostat and TRV's, we are able to help!

London HIU Service Repair Specialists

We have continued  to operate honestly in London for years, leading us to be vetted and audited by Which to become a trusted trader. This process continues annually, including with all our Which reviews. RBG Services engineers have been trained by manufacturers on numerous HIU systems, with home owners and the biggest property management companies in the country trusting us for years to maintain their HIU systems, completing annual HIU servicing, HIU repairs when needed, and HIU installations as a last resort.

If your HIU is beyond economical repair, and the the cost to replace it is unexpected, we have options to help spread the cost of a new installation, easing the financial burden . For property owners, landlords or management teams needing to replace their HIU’s, a very important point to mention is we only install HIU’s that have been registered to BESA’s HIU test regime and have been verified, which include Worcester Bosch and Danfoss.
