We get it.
There’s nothing worse than waking up to a cold house, no hot water, and a boiler that’s decided to take the day off. If you’ve found yourself googling boiler not working while wrapped in a blanket, you’re not alone, and you’re definitely in the right place.
At Rowlen Boiler Services, we’ve been keeping homes warm across Sutton and the surrounding areas for over 50 years. We’ve seen every boiler issue you can imagine such as strange noises, flashing error codes, pilot lights that won’t stay lit, and even frozen pipes on a Monday morning. So if your boiler’s acting up or completely out of action, we know exactly how to help.
Before you panic, let’s walk through what might be going on, what you can do now, and when to give us a call. We’re here to make this easy.
Quick Checks You Can Do
Sometimes, a boiler not working can be caused by something simple. Before you assume the worst, there are a few quick things worth checking:
Is the Power On?
It sounds basic, but if there’s been a power cut or your fuse box has tripped, your boiler might just need a quick reset. Look for any lights or error messages on your boiler’s display. If it’s completely blank, check your fuse board first.
What’s the Pressure Saying?
Most boilers need a certain pressure to work properly. You’ll usually see a dial that should read between 1.0 and 1.5 bar when the system’s cold. If it’s too low, the boiler might have shut down to protect itself. You may be able to top it up using the filling loop, if you’re unsure, give us a ring and we’ll talk you through it.
Got Gas?
Try lighting your hob or cooker. If there’s no flame, the issue might be with your gas supply, not the boiler. If you’re on a prepay meter, check you’ve got credit.
Frozen Pipe? (It Happens a Lot in Winter)
That plastic pipe running outside from your boiler? That’s your condensate pipe, and when it freezes, your boiler might refuse to fire up. If you think that’s the issue, pour warm (not boiling) water over the pipe, then try restarting the boiler.
Still no luck? Don’t worry. That’s where we come in.
Common Reasons Boilers Stop Working
Not all boiler problems are DIY-friendly, and that’s okay. We’re here to take the guesswork out of it.
Here are a few of the issues we get called out for the most:
Faulty Thermostats
If your thermostat’s stopped communicating with your boiler, nothing will turn on when it should. Sometimes it’s a battery problem. Other times, the unit just needs replacing. Either way, we can get it sorted quickly.
Pilot Light Keeps Going Out
Still using a boiler with a pilot light? If it keeps going out, it could be a sign of a faulty thermocouple or a draft blowing it out. We’ll inspect it safely and make sure it’s nothing more serious.
Loud Noises or Kettling
Hearing banging, clanking, or what sounds like a boiling kettle? That’s usually a sign of a buildup in the system like air, sludge, or limescale. We can carry out a system clean or flush to get things flowing smoothly again.
Repeated Lockouts or Error Codes
If your boiler keeps shutting down or displaying cryptic messages, we’ll run diagnostics using our fault-finding equipment to get to the root of the problem. Most issues are fixable with a part replacement or adjustment.

Book Your Annual Service
We can’t say this enough: regular servicing saves you money, stress, and cold mornings. A yearly check keeps everything running smoothly and helps catch problems early, before your boiler suddenly stops working.
During a service, we:
- Check all components
- Clean key parts
- Test safety features
- Catch wear and tear before it causes breakdowns
Most warranties even require annual servicing, so it’s worth staying on top of it.
If it’s been a while since your last boiler service or you’re not sure if it’s ever been done, let’s get you booked in. We’ll give your system the full treatment and leave you with peace of mind.

We deal with boiler problems every single day from minor faults to full system breakdowns, and we know how frustrating it can be when things stop working just when you need them most. That’s why we act fast, keep things clear, and always focus on getting your heating and hot water back without delay.
