"Listed townhouse, drain collapse under the flags. KJ CCTV-surveyed, re-lined it without excavating and worked with the conservation officer. No damage to the setts. Fair quote."

Leak Detection in Chester — Insurance-Friendly Report
In short
Chester listed properties often go through Ecclesiastical Insurance — a specialist heritage insurer whose reporting template asks for building-fabric impact alongside the plumbing cause, and the report has to reflect that.
Response: 80–120 minutes across CH1–CH4
PDF report within 48h
£50 diagnostic — refunded if unlocatable
Insurer-accepted report format
Incoming water pressure across Chester
Incoming mains typically 3.2–4.2 bar across CH1–CH4. Some historic city-centre streets on PRV-reduced supplies 2.6–3.4 bar.
Every report we send in Chester prints the incoming static and dynamic pressure at the stopcock alongside the cause statement — pressure is often half the leak story and adjusters want to see it.
What leaks in Chester actually look like
Chester leak-trace work leans toward listed-property traces (Ecclesiastical Insurance reporting), Upton/Vicars Cross semi push-fit failures, and Blacon/Saltney ex-council traces.
Most common Chester leak sources we see
- Historic pipework joint failures in Chester listed properties
- Push-fit joint failures on Upton/Vicars Cross semi mains
- Concealed heating leaks under Blacon/Saltney ex-council tile floors
- Failed shower waste seals in Chester conservation-property en-suites
- Central-heating pinhole corrosion in older Chester rad circuits
What Chester insurers actually want in the report
Common Chester insurers: Aviva, LV=, Hiscox on higher-value Chester detached, Ecclesiastical Insurance on listed properties. United Utilities is drainage authority.
Chester insurers on listed properties (particularly Ecclesiastical) want a building-fabric impact statement alongside the plumbing cause — heritage lime plaster damage is treated differently from modern gypsum damage. Get it in the report.
Every insurance-friendly report includes: date and address, incoming static and dynamic pressure readings (bar), thermal-imaging screenshots with location markers, acoustic-tracer transcript, dye-test results where applicable, non-invasive access method used, engineer name and qualification, and a plain-English cause statement. Delivered as a single PDF within 48 hours.
How KJ approaches a leak trace in Chester
- For listed properties, use Ecclesiastical Insurance's heritage-property reporting template
- For historic drainage, thermal-image the wall fabric alongside the pipework
- Log static AND dynamic pressure at the incoming stopcock
- For Upton/Vicars Cross semis, distinguish push-fit from capillary on the mains run
- Deliver the PDF report within 48h with building-fabric impact identified on listed properties
Transparent Chester leak-detection cost band
£185–£380 for a non-invasive trace and report; £520–£880 for listed-property investigation.
Every price is confirmed in writing after the £50 diagnostic. Nothing beyond the trace itself starts without your approval, and the £50 is refunded if the leak can't be located non-invasively.
Why you shouldn't sign a Chester rip-out quote before the report
A Chester heritage-property pattern is charging a "heritage surcharge" for standard trace work. There is no heritage surcharge — the reporting template is different, not the price.
Our promise on every Chester leak-detection call-out: £50 to attend, log pressure and run the first non-invasive trace; an insurance-friendly PDF report within 48 hours; and refund of the £50 if the leak can't be located non-invasively.
