Emergency Boiler Repair Services We Cover
When a boiler fails, every hour without heating or hot water counts. OGB Sussex provides emergency boiler repair across East and West Sussex — including Brighton, Hove, Worthing, Crawley, Eastbourne and surrounding areas. Our Gas Safe registered engineers work on all makes and models, diagnosing breakdowns, leaks, lockouts and pressure faults. We’re available 24 hours a day, 7 days a week, 365 days a year.
Our Gas Safe registered engineers work on all makes and models, and vans carry the parts that fail most often, so the majority of boiler breakdowns are repaired on the first visit rather than booked in for a second.

How we work
Three steps from phone call to fixed
1
Call
We ask what the boiler is doing, what make it is and whether you have any heating or hot water at all, 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, test the boiler under load, tidy up and tell you plainly what failed and whether the unit has life left in it.

Boiler repair, answered
Yes. Our Gas Safe registered engineers work on all makes and models, combi, system and conventional, including older units where parts are still available.
Most boiler breakdowns are fixed on the first visit. Our vans carry the components that fail most often, so a same-day repair is the normal outcome rather than the exception.
Yes. The emergency line is answered 24/7, including weekends and bank holidays, by our own team in Hove rather than an outsourced call centre.
Turn the boiler off at the switch, close the water supply to it if you can reach the valve, and put a container under the leak. Call us and we will talk you through it.
If the fault is a major component on an older boiler, the repair cost can approach the price of a new unit. We will tell you plainly which way the numbers fall and quote for both.
We are Gas Safe registered, fully insured, Checkatrade rated and DBS-checked. Our registration number is shown at the top of this page. We also hold SafeContractor, CHAS and SSIP accreditation.
We aim to call you back within 90 minutes of your call, anywhere in Sussex, and give you an honest arrival window for the engineer on that call.
