Blocked Drain in Liverpool — £50 Diagnostic, Jet Before You Dig
In short
Toxteth Georgian terraces have some of the oldest shared laterals I ever put a camera down — Victorian brick-arch sewers converted to salt-glaze in the 1920s and never touched since.
Response: 80–120 minutes across L1–L18
£50 diagnostic — refunded if we can't clear it
Typical cost band: £85–£180 for a jet; £220–£420 with CCTV.
Fair fixed quote in writing before any work
What blocked-drain calls in Liverpool actually look like
Liverpool blocked-drain work splits three ways: Georgian terrace shared laterals in L8/L15, block-managed stack blockages in Docklands apartments, and single-property clay-lateral blockages in the L17/L18 semi belt.
Where your responsibility ends: L8 (Toxteth, Dingle) Georgian terraces have shared laterals under lanes and mews. Docklands and city-centre apartments have block-managed internal drainage to ground-floor chambers. L17/L18 semis have single-property laterals.
When a Liverpool blocked drain becomes United Utilities's problem
Drainage undertaker for Liverpool: 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. Toxteth Georgian back-lane shared runs are UU laterals — 0345 672 3723 for free clearance in principle. In Docklands, block-managed drainage is usually the freeholder's responsibility, not UU's.
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.

Recent Liverpool drainage customer reviews
"Lead pipe under the bay had a slow weep. Renewed in MDPE, fitted a lever stopcock and pressure-tested. £50 diagnostic came off the final bill."
— Joseph R., Toxteth (L8) · Lead main replacement, L8 Georgian terrace
"1930s semi, cylinder coil furred solid. Replaced the cylinder, sorted the immersion and left the airing cupboard tidier than he found it."
