How much does drain unblocking cost in the UK? (2026)
Verified UK drain unblocking prices for 2026: rodding, jetting, gully and toilet clearance, CCTV surveys and call-out fees, plus the one check that can make the whole job free.
Unblocking a drain in the UK in 2026 typically costs £80 to £175, depending on whether it needs rodding, jetting, or a more involved clearance. Simple jobs like a blocked toilet or sink are £50 to £70. The figure that catches people out is the call-out fee, and the figure that saves them money is finding out the blockage is the water company's responsibility, not theirs.

Practical guidance (industry standard)#
Check who owns the blockage first#
This is the single most valuable check, because it can make the whole job free. The rule of thumb:
- Inside your property boundary: your private drain, your cost.
- Outside your boundary, or shared with a neighbour: a lateral drain or sewer, usually the water company's responsibility. They clear these at no charge to you.
If a blockage backs up from a manhole near the boundary, or affects more than one property, contact your water company before paying a private firm. Keep a record of the call. See Citizens Advice on drain responsibility for how the boundary is defined. The exception is a private or unadopted sewer, where the owners served by it share the cost.
Call-out fees and the out-of-hours trap#
A typical in-hours call-out is £50 to £100, and many firms credit it against the job if they clear the blockage. The trap is the emergency premium: a same-day, evening, or weekend visit can double the call-out, and a slow drain that could wait until Monday rarely needs paying an emergency rate. Ask whether the call-out is included in the clearance price, and whether the job genuinely needs an out-of-hours visit.
When a CCTV survey is worth it#
A basic CCTV survey is around £90; a full survey with mapping and a written report is £250 to £350. It earns its cost when:
- Blockages keep recurring in the same spot (a sign of root ingress, scale, or a collapse, not a one-off).
- You are buying a property and want to know the drain condition.
- An insurer or the water company needs evidence of the cause.
Paying for a survey on a one-off blockage that rodding would clear is over-spec.
What affects the price#
- Method. Rodding is cheapest; jetting and descaling cost more; excavation to reach a collapsed pipe is the most expensive by far.
- Access. A drain under a patio, decking, or extension costs more to reach.
- Cause. Fat and wipes clear easily. Roots, scale, and collapses need cutting, descaling, or repair.
- Region. London and the South-East run highest; the North and Midlands sit at or below the national average.
- Timing. Out-of-hours and emergency visits carry premiums.
Drain work inside a plumber or builder quote#
On a renovation, drainage can appear as a vague "drains" or "below-ground" line. A fair quote names the method (rod, jet, survey) and whether excavation is allowed for. For judging a plumber's price more broadly, see is my plumber's quote reasonable, and for groundwork-heavy jobs the garden landscaping guide covers drainage in the round.
Red flags in a drain quote#
- Emergency premium on a non-urgent job. A slowly draining sink is not a same-day emergency. The premium should match the urgency.
- No method named. "Unblock drain, £350" with no rodding, jetting, or survey detail cannot be checked against a fair rate.
- Survey or excavation pushed before rodding is tried on a first, simple blockage.
- No mention of checking responsibility where the blockage is clearly near or beyond the boundary, which can mean paying for work the water company would do free.

Frequently asked questions
- How much does it cost to unblock a drain in the UK in 2026?
- A straightforward domestic drain clearance is roughly £80-£100, drain rodding £80-£145, and high-pressure jetting £70-£175 (MyJobQuote, 2026). Simple jobs like a blocked toilet or sink are £50-£70. Most homeowners pay around £85 for a standard blockage, with call-out fees and out-of-hours rates added on top.
- What is the call-out fee for an emergency drain unblocking?
- A typical in-hours call-out is £50-£100, often credited against the job if the firm clears the blockage. Evenings, weekends, and emergency same-day visits carry higher call-out charges. Always ask whether the call-out is included in the clearance price or charged separately before booking.
- How much is a CCTV drain survey?
- A basic CCTV drain survey is around £90, while a full survey with drain mapping and a written report runs £250-£350. A survey is worth it where blockages keep recurring, before buying a property, or to find out whether a collapse or root ingress is the real cause rather than a simple blockage.
- Can I get my blocked drain cleared for free?
- Sometimes, yes. You are responsible for drains inside your property boundary, but lateral drains and sewers outside the boundary (including shared runs) are usually the water company’s responsibility, and they clear those at no charge. Before paying a private firm, check who owns the blocked section. Contact your water company first if the blockage may be beyond your boundary.
- Why is my drain quote so much higher than the average?
- Usually because the job is not a simple blockage. Jetting, a CCTV survey, root cutting, descaling, or excavation to reach a collapsed pipe each add cost. A fair quote names the method and the access. A high lump sum with no breakdown, or an emergency premium applied to a non-urgent job, is worth questioning.
