Whitebox Heating provides fully qualified, Gas Safe registered heating engineers in Horsham and across West Sussex. From radiator installations and power flushing to full central heating system upgrades, we handle all types of heating work to the highest standard.
Horsham is one of West Sussex's most desirable market towns, known for its historic Carfax and mix of Victorian terraces, inter-war semis, and modern developments. The town's wide variety of property ages means our engineers regularly work on everything from traditional gravity-fed systems to the latest high-efficiency combi boilers.
We cover central Horsham, Roffey, Broadbridge Heath, Southwater, and the surrounding villages. As a busy market town with a growing population, we prioritise rapid response to keep homes warm and hot water flowing.
Our Gas Safe engineers in Horsham handle the full range of central heating work. From adding a new radiator to replacing your entire central heating system, we approach every job with the same professionalism and attention to detail.
Over time, sludge and magnetite build up in your radiators and pipework, reducing heat output and putting strain on your boiler. A professional power flush by our Horsham engineers can restore your heating system to near-new efficiency in a single day.
We fit and configure smart thermostats (Nest, Hive, Drayton Wiser), programmers, zone valves, and thermostatic radiator valves (TRVs). Upgrading your heating controls is one of the most cost-effective ways to cut your energy bills.

You may need one if some radiators are cold at the bottom, your boiler is noisy, or your system is slow to heat up. We check whether a power flush is needed during any service or repair visit.
