A drainage specialist clears blockages, runs CCTV surveys, and repairs or relines damaged pipework. Establish ownership before you accept a bill: since the 2011 private-sewer transfer, most shared drains and the lateral drain beyond your boundary became the water company’s responsibility to maintain, and they will normally attend a blockage there at no charge to you.

Quick answer
A drainage specialist clears blockages, runs CCTV surveys, and repairs or relines damaged pipework, typically £150–£500 for a callout. Ownership decides who pays: since the 2011 private-sewer transfer, most shared drains and lateral drains beyond your boundary became the water company’s responsibility. Establish which side of the boundary the blockage sits on before you accept a bill.
| Job | Drainage specialist | Plumber | Groundworker |
|---|---|---|---|
| Unblock a soil stack or gully | ✅ Recommended | ✅ OK | ❌ No |
| CCTV survey with coded report | ✅ Recommended | ⚠️ Rare | ❌ No |
| Reline a cracked drain | ✅ Recommended | ❌ Not equipped | ⚠️ Excavation only |
| New drainage run for an extension | ✅ Yes | ⚠️ Sometimes | ✅ Recommended |
| Leak under a kitchen sink | ⚠️ Overkill | ✅ Recommended | ❌ No |
Before paying to clear a blockage in a shared run, call your water company. If it sits in a lateral drain or shared sewer adopted in 2011, they will normally attend at no charge — and a contractor has no incentive to tell you that.
