Who Owns the Drains on My Property?

Drain ownership in the UK determines who is responsible for maintenance and repairs — and getting it wrong can mean paying for work that someone else should cover. The rules changed significantly in 2011 when most shared drains were transferred to water company ownership, but many homeowners are still unclear about which pipes they own.

What to Look For

  • Private drains: serve only your property and are within your boundary — YOUR responsibility
  • Lateral drains: connect your property to the public sewer — WATER COMPANY since 2011
  • Shared drains: serve 2+ properties — WATER COMPANY since 2011 (pre-existing)
  • Public sewers: serve the wider area — always WATER COMPANY
  • Highway drains: under public roads — LOCAL COUNCIL responsibility
  • New shared drains built after 2011: may have different adoption arrangements

How We Diagnose the Problem

We conduct a CCTV survey with drain tracing to map your entire drainage system, clearly showing which pipes serve only your property (private — your responsibility) and which are shared or connect to the public sewer (usually water company). We cross-reference with official sewer maps.
