Central Heating Repair Services We Cover
A heating system that fails in January is an emergency, not an inconvenience. OGB Sussex repairs central heating across East and West Sussex — including Brighton, Hove, Worthing, Crawley, Eastbourne and surrounding areas. We work on radiators, thermostats, pumps, valves and controls, and power flush systems clogged with sludge. We’re available 24 hours a day, 7 days a week, 365 days a year.
Our Gas Safe registered engineers work across boilers, radiators, pumps and controls, and vans carry the parts that fail most often, so the majority of heating faults are repaired on the first visit.

How we work
Three steps from phone call to fixed
1
Call
We ask which radiators are cold, whether you have hot water, and what the thermostat and boiler are doing, so the engineer arrives knowing what to expect.
2
We arrive
Within 90 minutes you get a call from us with a named engineer and a realistic arrival window, another call when they are on the way, and then we turn up inside the window we gave you.
3
Problem solved
We repair the fault, balance the system, test it up to temperature and tell you plainly what failed and whether anything else is close behind it.

Yes. We fit and commission zoning, timers and smart thermostats, and set them up with you before we leave.
