First check where the leak is coming from and whether it's somewhere other than the central heating - look at the seal around the bath or the roof, for instance.
Confirmed it's the central heating that's leaking? To limit the damage, turn off your heating and your cold water stop tap, then book a callout.
Not sure how to turn off your heating? Check your user manual.
- If you have an open vented system - with a cistern in the loft - it can take a bit of time for the leak to stop, unless the system is completely drained. So don't worry if the leak doesn't stop immediately, it soon will.
What could be the cause?
A possible cause of the leak is a punctured pipe, especially if you've had some DIY or building work done in your home recently. To see if you're covered under your HomeCare® agreement, check your terms and conditions.
