Boiler Breakdowns During Cold Snaps
Few things disrupt daily life more than waking up to no heating or hot water. One of the most common urgent heating engineer callouts we receive is for boilers that suddenly give up during freezing weather.
Why it Happens
When the temperature drops, your boiler has to work much harder. Frozen condensate pipes, worn-out parts, or incorrect pressure can easily cause it to shut down. Boilers that haven’t been serviced recently are particularly vulnerable and often fail just when you need them most.
How to Avoid It
- Book your annual boiler service before winter really sets in.
- Insulate external condensate pipes to stop them freezing.
- Keep your heating on low when you’re away during cold weather.
- Learn to check boiler pressure (it should usually be between 1 and 2 bars).

Radiators Not Heating Evenly Or At All
Cold patches or completely unresponsive radiators can be frustrating, especially when every room feels a different temperature. It’s one of those problems people ignore until half the house feels like an icebox.
Why it Happens
Air trapped in the system or a build-up of sludge can block circulation. Sometimes, a single closed valve or imbalance in the system causes uneven heating.
How to Avoid It
- Bleed your radiators every few months to release trapped air.
- Schedule a power flush when recommended by your engineer.
- Don’t overlook one cold radiator — it’s often the first warning sign.
- Follow our emergencies guide to check simple fixes before you call.
If your radiators are struggling, our heating engineer emergencies Battersea team will restore warmth quickly and safely.
Leaking Boilers Or Pipework
A leaking boiler is more than an inconvenience, as it can be dangerous if water reaches electrical components. It’s one of the most serious reasons we get called for urgent heating engineer support.
Why it Happens
Leaks often develop from worn seals, corroded fittings, or ageing internal parts. Small leaks can go unnoticed for weeks, quietly damaging your flooring or nearby electrics.
How to Avoid It
- Check the area around your boiler regularly for dampness or puddles.
- Don’t ignore small drips — they rarely stay small for long.
- Book a routine boiler service to spot wear-and-tear before it worsens.
If you notice a leak, call 02086822244 for fast help in Battersea. Our team responds quickly to stop further damage and keep your home safe.
Loss Of Boiler Pressure
If your boiler pressure drops below 1 bar, it can cause your heating to cut out or operate erratically. It’s a subtle issue that often creeps up unnoticed until the system shuts down entirely.
Why it Happens
Leaks in the heating system, recently bled radiators, or faults with the pressure reducing valve are common culprits. Occasionally, pressure loss can also be linked to a frozen pipe in winter.
How to Avoid It
- Check the pressure gauge weekly. It should read between 1 and 2 bars.
- Top up the system safely using your boiler’s filling loop (see your manual).
- Call an engineer if you notice recurring drops, as it could signal a hidden leak.
- During freezing weather, check that your external pipes aren’t blocked with ice.
If you’re dealing with pressure problems, we’re always ready for a callout to get your system back on track.
Frozen Condensate Pipes
Every winter, our team handles numerous calls for frozen condensate pipes. When this happens, your boiler shuts down automatically for safety, leaving you without heat or hot water.
Why it Happens
Condensate pipes carry acidic wastewater from your boiler to the drain. Because they’re often installed outside, they’re highly susceptible to freezing during cold weather.
How to Avoid It
- Insulate the pipe using weatherproof foam.
- Keep your heating on a low setting in freezing conditions.
- Act quickly if you hear gurgling sounds or see an error code on the boiler.
- This is one of the most time-sensitive emergencies in Battersea, and our team is fully equipped to handle it quickly and efficiently.
