Heating breakdowns hit hard across Crawley's mix of housing. Combi boilers crammed into the terrace cupboards of Furnace Green and Bewbush lock out on cold mornings, moderately hard Sussex water scales heat exchangers in Broadfield and Southgate, and older Northgate and Ifield homes still nurse tired back-boilers. Frozen condensate pipes catch out Maidenbower and Pound Hill boilers in frosts. Our heating engineers restore heat and hot water fast.
Crawley is a post-war West Sussex new town built as a ring of distinct neighbourhoods around an older village core, with 1950s-60s council-built housing, later 1980s estates at Maidenbower and Broadfield, and the constant pressure of sitting right against Gatwick Airport.
Enter your postcode and EmergencyLines finds the nearest available heating engineer to you - day or night, weekends and bank holidays included. You get a number, you call it, and you speak to the heating engineer directly. No call centre, no middleman, no waiting on hold.
Crawley's water is hard (around 245 mg/l), so limescale risk to boilers and cylinders is high - scale on the heat exchanger is a leading cause of "kettling", lockouts and weak hot water here. With 26 air-frost days a year, a cold snap is when a struggling boiler finally locks out.

A quick steer before you decide - your Crawley engineer confirms it on the day.
Crawley sits on hard water (≈245 mg/l), so scale on the heat exchanger shortens boiler life here - worth weighing in the call, along with a scale reducer on any new install.
These are the heating callouts we see most across Crawley, shaped by the local housing and weather:
No heat from ageing combi boilers and limescale-clogged heat exchangers come up again and again here - usually down to the age and style of Crawley's housing. Whatever the cause, the priority is the same: a verified heating engineer covering West Green, Southgate and the rest of the city can make it safe quickly and tell you the cost before any work begins.
Pick what's happening and we'll give you the likely cause and the safe first step - then enter your postcode to reach a verified Crawley heating engineer.
Likely cause: Often a diverter valve, a boiler fault or low pressure rather than the whole boiler.
Do this now: Check the pressure gauge reads about 1-1.5 bar and the gas and power are on, then call a Gas Safe engineer.
Likely cause: Usually a pump, motorised valve or thermostat fault - not a dead boiler.
Do this now: Try bleeding the radiators and check the thermostat is calling for heat; book an engineer if not.
Likely cause: The boiler has locked out to keep itself safe.
Do this now: Note the fault code, reset once, and if it locks out again leave it and call a Gas Safe engineer.
Likely cause: A leak on the system or a failed valve is dropping the pressure.
Do this now: If you can see water, turn the boiler off; an engineer should find the leak before topping up repeatedly.
Likely cause: Air, sludge or - in hard-water areas - limescale on the heat exchanger.
Do this now: Bleed the radiators; persistent noise or cold spots usually need a flush or descale.
A few minutes of prep can limit the damage and get you sorted faster once the heating engineer is on the way:

Every Crawley postcode and the surrounding West Sussex - from Three Bridges, Northgate, West Green, Southgate, Tilgate and Furnace Green, through to the outer suburbs. Wherever you are in the city, there's a vetted local heating engineer on the network.
In Crawley, no heat from ageing combi boilers and limescale-clogged heat exchangers top the list - often down to the city's older housing stock. Describe what's happening on the call and your heating engineer arrives prepared.
Yes - a boiler breakdown is the most common heating emergency in Crawley. Enter your postcode and you'll see Gas Safe registered engineers available right now, day or night. You call directly, describe the fault or lockout code, and agree timing and price before any work starts.
Treat it as an emergency. Call the National Gas Emergency Service on 0800 111 999 straight away - it's free, answered 24/7, and the same number wherever you are. Open doors and windows, turn the gas off at the meter if you can, and don't touch light switches, electrics or naked flames until it's made safe. In Crawley the gas mains are maintained by SGN, who attend the emergency; a Gas Safe registered engineer then repairs the actual fault on your appliance or pipework once the supply is confirmed safe.
No - it costs nothing to enquire. You only pay once you've spoken to the heating engineer, agreed the work and it's complete. There's no charge just to find out who's available near you in Crawley.
Yes. Combis squeezed into the terrace cupboards of Furnace Green, Bewbush and Southgate commonly lock out on low pressure, fan or ignition faults on cold mornings. We attend quickly, diagnose the fault and get heat and hot water back where we can on the first visit. We carry common parts, and if a component needs ordering we'll make the situation safe and tell you exactly what's required and when.
Moderately hard Sussex water scales up boiler heat exchangers across Broadfield, Tilgate and the older estates, gradually choking hot-water flow until the combi can barely keep up. We diagnose whether the heat exchanger is scaled, flush or descale where possible, and advise on a system flush or scale-reduction measures to protect it. Tackling the scale restores performance and helps the boiler last longer in Crawley's water.
Decades-old systems in West Green, Tilgate and Northgate fill with sludge over time, which settles in the lower radiators and leaves them stone cold while upstairs stays warm. We check circulation and the pump, then carry out a power flush or chemical clean to clear the sludge and rebalance the system. Adding an inhibitor afterwards keeps it clean, and we'll flag any failing pump or valve found along the way.
