"Back-to-back terrace, boiler died on a Sunday morning. Engineer diagnosed the fan by lunchtime, sourced the part in Leeds and had heating back on before tea. £50 diagnostic came off the bill."

£50 diagnostic — refunded if we can't clear it
Typical cost band: £85–£180 for a jet; £220–£420 with CCTV.

What blocked-drain calls in Leeds actually look like
Leeds blocked-drain work is heavily student-tenancy driven in LS4/LS6 — wet-wipes, food waste and the occasional dropped bathroom bin block the shared alley run. Owner-occupier stock in LS7/LS16/LS17 leans toward root-invaded clay laterals and single-property blockages.
Where your responsibility ends: LS6 (Headingley, Hyde Park) student terraces share back-to-back runs; LS7–LS17 semis have single-property laterals to the front sewer.
When a Leeds blocked drain becomes Yorkshire Water's problem
Drainage undertaker for Leeds: Yorkshire Water
Under the 2011 private-sewer transfer, any shared drainage (serving more than one property) and the lateral drain from your boundary to the public sewer belongs to Yorkshire Water. Anything inside the boundary — down to and including the last chamber on your property — is yours. Any LS6 back-to-back shared alley run is a Yorkshire Water lateral — free clearance if the landlord is willing to wait for YW's own crew (0345 124 24 24). Most landlords aren't — that's when we get the call.
Yorkshire Water 24/7 sewer-flooding line: 0345 124 24 24 — free of charge. Call them first if the blockage is beyond your boundary or on shared pipework.
The blockages we see most in Leeds

How Kevin approaches a blocked drain in Leeds
- For LS6 lets, notify the neighbouring properties before jetting a shared alley run
- Rod the customer's chamber first before jetting shared laterals
- CCTV-survey any repeat blockage — LS17 root ingress is common
- For landlord jobs, quote the cheapest safe clear and give a separate lining opinion
- Log the Yorkshire Water case number on any shared-lateral clearance

Why you shouldn't be sold an excavation in Leeds without a camera survey
A common LS6 landlord scam is invoicing tenants for a shared-lateral blockage that is 100% Yorkshire Water's responsibility. Ask for the CCTV footage and the exact location of the blockage before paying anything.
Our promise on every Leeds 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.

Recent Leeds drainage customer reviews
"HIU in a Candle House apartment was giving intermittent hot water. Two other plumbers had walked away. KJ knew exactly what a Danfoss looked like — cleaned the strainers, replaced a sensor, sorted."
— Marcus J., Granary Wharf · HIU repair, Leeds city centre
"1930s semi, upstairs rads always cold. Proper diagnosis, magnetic filter fitted and a light flush — didn't oversell a full power flush. Refreshing."
