Drain Unblocking Cost UK 2026
Clearing a blocked drain costs £80–£250 for most call-outs, a CCTV survey £90–£350 and high-pressure jetting £150–£400. The first question is free: a blockage past your boundary in a shared sewer is usually the water company's job, not yours.
Drain work cost by job — 2026
Daytime prices; out-of-hours call-outs add 50–100%. Repairs assume the CCTV survey has located the fault first.
| Job | Typical cost | Time | Notes |
|---|---|---|---|
| Rodding a simple blockage | £80–£180 | Under an hour | The common kitchen or outside-gully job |
| High-pressure jetting | £150–£400 | 1–2 hours | Grease, scale and stubborn blockages |
| CCTV drain survey | £90–£350 | 1–2 hours | Finds the fault; needed before any repair claim |
| Patch lining a cracked section | £300–£900 | Half a day | No-dig repair from inside the pipe |
| Excavated drain repair | £600–£2,500 | 1–3 days | Digging down to replace a collapsed run |
| Root cutting | £200–£500 | Half a day | Mechanical cutting plus a re-line to stop regrowth |

What changes the cost
| Cost factor | Typical impact | Why it matters |
|---|---|---|
| Where the blockage sits | the ownership question | Drains inside your boundary are yours; lateral drains and shared sewers beyond it belong to the water company - check before paying anyone |
| Access to the run | ±25% | A liftable manhole cover makes a cheap job; no access chamber makes an expensive one |
| Out of hours | +50–100% | A flooding kitchen at midnight pays emergency rates - if it can wait for morning, let it |
| Cause of the blockage | decides recurrence | Wipes and grease clear and return; roots and cracked pipes need the repair, not another jetting |
| Insurance and cover plans | worth checking first | Home emergency cover and some water companies include unblocking - many people pay twice |

Getting it priced properly
1. Check whose drain it is first
Since 2011 lateral drains and shared sewers are the water company's responsibility. Two houses on the run past your boundary usually means the call is free.
2. Ask for the CCTV footage
If a survey finds damage, you are owed the recording - it is the evidence for an insurance claim or a second quote.
3. Fix causes, not symptoms
A drain that blocks twice a year has a defect. Jetting it annually costs more over five years than lining it once.

Drain unblocking — frequently asked questions
Around £80–£250 for a standard daytime call-out with rods, and £150–£400 if it needs high-pressure jetting. Out-of-hours emergency rates run 50–100% higher.
You own the drains inside your boundary that serve only your home. Lateral drains beyond the boundary and sewers shared with neighbours have belonged to the water company since 2011 - report those to them, free.
For a recurring blockage, yes - £90–£350 to find out whether the cause is habit or a defect. Buyers also use them on older houses before exchange, and insurers ask for the footage on subsidence-adjacent claims.
Buildings insurance usually covers accidental damage to underground services for the section you own; wear and tear and blockages themselves are usually excluded. Home emergency add-ons often cover the unblocking call-out.
