Is this something I should ignore for now?
No. Boiler and heating faults usually get worse if the underlying cause is left unresolved, especially if the boiler is shutting down or leaking.

Why Is My Boiler Leaking Water?
If water is leaking from your boiler or from pipework directly around it, the leak should be taken seriously. The source may be small at first, but it usually points to a fault that needs repair.
What a boiler leak can mean
Leaks can come from pressure-related parts, worn seals, damaged components or pipework connections near the appliance. The visible drip is often only the symptom.
Why leaking boilers should be prioritised
A leak can lead to pressure loss, repeated shutdowns and damage around the appliance, and it may get worse quickly once the boiler heats up.
When to book an urgent repair
If the boiler is actively leaking, pressure is falling or the leak is near electrics, book an urgent repair visit rather than waiting to see if it settles down.
Do not DIY these repairs
- Do not open the casing or tighten internal components
- Do not ignore water around electrical parts or controls
- Do not keep using the system if the leak is active and worsening
What usually fixes it
- Repairing a failed seal or valve
- Replacing a pressure-related component
- Resolving internal component leaks after diagnosis
Frequently asked questions
Can I safely diagnose the internal fault myself?
No. You can carry out basic visual checks, but internal boiler parts and gas-related work should be left to a qualified engineer.
Will this automatically mean I need a new boiler?
Not always. Many common faults can be repaired once the real cause has been identified.
