If your boiler’s suddenly stopped working in Brighton or Hove, you’re not alone. We get these calls every week, especially when the temperature drops or the first proper cold snap hits off the coast. One minute everything’s fine, the next you’ve got no hot water and the radiators are stone cold.
As a local engineer, I’ve seen just about every boiler problem going across Brighton & Hove, from modern combi boilers in new flats near the Marina to older systems in Victorian terraces in Hanover. In this guide, I’ll run through the most common causes, a few simple checks you can safely do yourself and when it’s time to call for a proper boiler repair in Brighton.
Common Boiler Faults We See in Brighton
1. Low Boiler Pressure
If your boiler isn’t firing up and you can see the pressure gauge sitting below 1 bar, that’s often the culprit. Low pressure is one of the most common reasons for a boiler not working in Brighton homes.
Pressure can drop if there’s been a small leak somewhere, if the radiators have been recently bled or just over time. In older properties around Hove, we sometimes find very slight seepage on radiator valves that homeowners hadn’t noticed.
2. Frozen Condensate Pipe
When we get a cold spell with that sharp sea wind, condensate pipes can freeze. This usually affects boilers with an external plastic pipe running outside to a drain.
If the pipe is frozen, the boiler may display a fault code or make a gurgling noise before shutting down. It’s more common than you’d think, especially on properties that back onto open areas where the wind really cuts through.
3. No Power to the Boiler
It sounds obvious, but sometimes the issue is simply that the boiler has no electrical supply. We’ve been to jobs where a fused spur has been accidentally turned off during decorating or a fuse has blown.
Always check whether other nearby sockets or appliances are working before assuming the boiler itself has failed.
4. Thermostat or Timer Problems
If there’s no heating but you’ve still got hot water, or vice versa, it might be your thermostat or programmer rather than the boiler.
We often get calls from landlords who think the whole system has failed, when it turns out the tenant has accidentally adjusted the timer or changed the batteries in a wireless thermostat and not reset it correctly.
5. Ignition or Flame Failure
If your boiler tries to fire up but keeps clicking or shows a flame failure fault code, it could be an issue with the ignition, gas supply or internal components.
This isn’t something to investigate yourself. Anything involving gas needs a Gas Safe registered engineer.
Quick Checks You Can Do Before Calling an Engineer
Before you book a boiler repair in Brighton, there are a few simple things you can safely check.
- Check the boiler pressure gauge. Ideally it should sit between 1 and 1.5 bar when cold.
- Make sure the thermostat is switched on and set above the current room temperature.
- Confirm the boiler has power and the fused spur hasn’t been turned off.
- Look for any obvious error codes on the display and make a note of them.
- Check that your gas supply is working by seeing if your hob ignites.
If repressurising the boiler is something you’ve done before and feel confident doing, you can top it up using the filling loop. If you’re unsure, don’t guess. It’s better to call someone out than risk over-pressurising the system.
Important Safety Tips
If you suspect a gas leak, smell gas or feel unwell with headaches or dizziness, turn off the gas at the meter, open windows and leave the property. Call the National Gas Emergency number immediately.
Never remove the boiler casing yourself. Even if you’re handy with DIY, boilers contain sealed components and anything gas-related must legally be handled by a Gas Safe engineer.
If your carbon monoxide alarm has gone off, treat it as an emergency. Don’t reset it and carry on as normal.
When to Call for a Boiler Repair in Brighton
If you’ve done the basic checks and your boiler still isn’t working, it’s time to get a professional in. This is especially important if:
- The boiler keeps locking out even after resetting.
- You can hear unusual banging or kettling noises.
- There’s water leaking from the boiler.
- You have no heating or hot water at all.
- The fault code keeps returning.
For landlords, a broken boiler is more than an inconvenience. You have a responsibility to provide heating and hot water, particularly during colder months. We often prioritise these calls because we know tenants can’t wait days for a solution.
If you’re dealing with a boiler not working in Brighton in the middle of winter, don’t leave it hoping it’ll sort itself out. Small issues have a habit of becoming bigger, more expensive ones when ignored.
FAQs About Boilers Not Working
Why does my boiler keep losing pressure?
Usually it’s down to a small leak somewhere in the system or a faulty pressure relief valve. In some older Brighton properties, we find corrosion on pipework under floorboards that’s been slowly dripping for months.
Is it safe to reset my boiler?
Yes, using the reset button as instructed in your manual is fine. If the boiler locks out repeatedly, though, there’s an underlying fault that needs diagnosing.
How quickly can I get a boiler repair in Brighton?
That depends on the time of year and the nature of the fault, but during cold weather we always try to attend no heating or no hot water calls as quickly as possible, especially for vulnerable residents.
Should I repair or replace my boiler?
If your boiler is over 12 to 15 years old and experiencing repeated breakdowns, we’ll have an honest conversation with you about whether a repair is worthwhile. Some faults are straightforward fixes however older systems can become unreliable and inefficient.
