Blocked Drain in Oldham — £50 Diagnostic, Jet Before You Dig

Half the Saddleworth blockage calls I attend involve the same shared lateral running under four cottages that no-one has jetted since the 1990s.
Response: 50–85 minutes across OL1–OL9
£50 diagnostic — refunded if we can't clear it
Typical cost band: £85–£180 for a jet; £220–£420 with CCTV; excavation from £480 (never first choice).
Fair fixed quote in writing before any work
What blocked-drain calls in Oldham actually look like
Oldham blocked-drain work is dominated by silted shared laterals in Saddleworth stone-cottage groups, root-invaded runs in Failsworth and Chadderton terraces, and wet-wipe blockages in ex-council Royton semis. Combined sewers (rain and foul in one pipe) are still common in older Oldham stock.
Where your responsibility ends: Saddleworth (OL3) villages often have combined-sewer arrangements or shared laterals across two or three stone cottages — the deed pack is essential reading before excavation.
When a Oldham blocked drain becomes United Utilities's problem
Drainage undertaker for Oldham: United Utilities
Under the 2011 private-sewer transfer, any pipework serving more than one property, and any lateral drain from the boundary of your property to the sewer, is United Utilities' responsibility. That covers most back-alley shared runs and every stretch under the public highway. Saddleworth's older combined sewers still count as UU-owned public sewers — do not let anyone quote you for "private main drainage repair" without confirming the pipe is actually inside your boundary.
United Utilities 24/7 sewer-flooding line: 0345 672 3723 — free of charge. Call them first if the blockage is beyond your boundary or on shared pipework.

- For OL3, always read the deed pack for combined-sewer or shared-lateral arrangements

- CCTV-survey any repeat Failsworth / Chadderton blockage
- Photograph invert levels and chamber positions on every visit
- Log the UU case number on shared-lateral clearances

Why you shouldn't be sold an excavation in Oldham without a camera survey
A common Oldham tactic is quoting excavation on any blockage that doesn't clear in the first ten minutes. Insist on a camera survey before any digging — a £180 CCTV run has saved dozens of Oldham customers a £2,500 excavation.
Our promise on every Oldham blocked-drain call-out: £50 to attend and diagnose, a fair fixed quote in writing before any billable clearance or repair, and the £50 refunded if we can't clear the blockage we diagnosed.
