1. Boiler Breakdowns During Cold Snaps
One of the most frequent heating engineer emergencies in Battersea we’re called to is a boiler failure during cold weather. When your boiler fails, especially in winter, it disrupts your entire routine.
Why It Happens
Cold snaps put your boiler under pressure. Frozen condensate pipes, faulty parts, or incorrect system pressure can trigger a shutdown. Boilers that haven’t had annual servicing are most at risk.
How To Avoid It
-
Book an annual boiler service before winter
-
Insulate external condensate pipes
-
Keep your heating on low when away in cold weather
-
Learn how to adjust water temperature on a boiler for optimal performance

2. Radiators Not Heating Evenly Or At All
Uneven heating or cold radiators can significantly impact your comfort, particularly in multi-room homes. It’s a common issue and an early sign of system trouble.
Why It Happens
Air trapped in the system, closed valves, or sludge build-up can stop radiators from working correctly. This is more common in older systems or those with irregular maintenance schedules.
How To Avoid It
-
Bleed your radiators every few months
-
Get a power flush when recommended
-
Don’t ignore one cold radiator—act before it spreads
-
Refer to our emergency guide for what to check before calling
If your radiators are playing up, our emergency heating engineer service will quickly restore warmth.
3. Leaking Boilers Or Pipework
Leaking boilers are not only messy—they can become dangerous if water reaches electrical components. It’s one of the most urgent reasons for a callout to an emergency heating engineer.
Why It Happens
Leaks usually result from old fittings, failed internal seals, or corrosion. Small leaks often go unnoticed until they cause water damage or heating failure.
How To Avoid It
-
Inspect the area around your boiler regularly
-
Spot damp patches early and call before it gets worse
-
Keep up with boiler servicing to catch wear-and-tear issues
-
If you’re dealing with a sudden leak, request an urgent heating engineer in Battersea immediately
We respond quickly to leaks to prevent further damage.
4. Loss Of Boiler Pressure
Low pressure is another common issue that disrupts heating. Your boiler might work intermittently or shut down completely.
Why It Happens
Leaks in the system, recent radiator bleeding, or faults with the pressure-reducing valve can cause pressure loss.
How To Avoid It
-
Check your boiler pressure gauge weekly (ideal is 1–2 bars)
-
Know how to top up safely (consult the manual)
-
Don’t ignore recurring pressure drops—it could signal a leak
-
If cold weather is involved, also check for frozen pipes—learn how to defrost a frozen pipe
We’re always ready for an urgent callout in Battersea to resolve pressure problems fast.
5. Frozen Condensate Pipes
This is a seasonal emergency, but one that we see frequently. When the condensate pipe freezes, your boiler shuts down for safety reasons.
Why It Happens
Condensate pipes carry acidic wastewater from your boiler. Because these pipes often run outside, they’re vulnerable to freezing during winter.
How To Avoid It
-
Insulate the pipe with weatherproof foam
-
Keep the heating on low during freezing conditions
-
Act fast if you hear gurgling or see a fault code
-
