Make the observation useful
Record how quickly pressure changes and whether it follows heating use. Earlier boiler checks are useful evidence before hidden pipework is investigated.
A focused starting point
Central heating leak detection explains how a relevant investigation could proceed. The actual method depends on the system and findings.
What to put in your enquiry
- Where the sign appears and when it began
- The pattern around water use, heating or weather
- Earlier inspections, repairs or changes
- Your full postcode and access arrangements
If water is actively escaping
For immediate danger, keep away from unsafe areas and use the appropriate emergency or urgent assistance service. Website enquiries do not dispatch emergency help or guarantee an attendance time.
