• Written report (if requested)
• Quote for repair or next steps

Qualifications to look for

• Insurance (PLI) is a must
• Ask what tools they use (not all leak detection services offer the same tech)
• Experience with your property type is a bonus (e.g. old vs new builds)

Water leak detection in London: Homeowners vs renters

Homeowners

You’re usually responsible for finding and fixing leaks on your property, especially if it’s an internal issue. Keep hold of any documentation if you’re claiming through insurance. Your water supplier is only responsible if the leak is on the mains pipe before it reaches your property boundary.

Renters

Report the leak to your landlord or letting agent straight away. It’s their responsibility to sort the repairs, but flagging signs early helps prevent bigger damage (and hassle). If you need urgent help, always check if your tenancy agreement allows you to arrange your own emergency trades.
