How Much Does It Cost to Fix a Collapsed Drain? (2026 UK Guide)
What a collapsed drain costs to repair in the UK in 2026 — patch, relining or excavation — what drives the price, and whether insurance covers it.
Although a collapsed drain can be costly to fix, the price depends mostly on how it’s repaired. MyJobQuote’s collapsed drain repair cost guide (updated August 2026) puts a typical repair at around £850. It gives these figures for each method:
- Patch repair: £150 to £300
- No-dig relining: £80 to £150 per metre
- Partial pipe replacement: £600 to £1,100
- Dig up and replace: £250 to £650 per metre
Digging is often avoidable. Here is how the pricing works.
First, confirm it’s really collapsed
People use “collapsed” loosely. For example, a drain that is blocked, cracked or partly displaced has not failed in the same way. Each fault has a very different price.
That’s why a collapsed drain repair should start with a CCTV drain survey. It shows whether the pipe has really collapsed, where, and how far. A survey first can save money, since it stops you digging when a no-dig fix would do. It also helps to know the signs of a collapsed drain, such as repeat blockages, smells and sinking ground.
The three repair methods
1. Patch repair. For a single cracked or partly collapsed joint, the installer bonds a short resin patch inside the pipe. It is the cheapest structural fix, and it needs no digging.
2. Relining. For a longer damaged run, the installer fits a resin liner inside the old pipe. It hardens to form a new pipe with no joints. As a no-dig repair, it avoids the cost and mess of digging. The drain relining cost guide has more detail.
3. Dig up and replace. Where a pipe has fully collapsed, or is crushed out of shape, the damaged section has to come out. Because of the digging, this is the most costly route. The price rises with depth, hard access, and the cost of putting back a driveway or patio.
What changes the price most
- Depth and access. A shallow pipe under a lawn costs far less to reach than a deep one under a driveway or extension.
- Length of the damage. One joint is cheap to patch, while a long run costs more to reline or dig.
- Putting the surface back. Digging means restoring whatever was on top, and block paving or concrete add to the bill.
- Cause. If tree roots or a recurring blockage caused the failure, deal with the cause too, so the repair lasts.
Ground movement plays a part in some areas. The city pages cover former mining ground in Stoke-on-Trent, Black Country clay in Wolverhampton and seasonal clay movement in Leicester. The list of cities covered has the rest.
Does insurance cover a collapsed drain?
Sometimes. Many buildings policies cover sudden, accidental damage to underground pipes you’re responsible for. Policies often exclude gradual wear, however, so check yours. An insurer may ask for evidence, such as a WRc-coded survey report. That is one more reason to survey before you repair. Before you claim, check whether home insurance covers drains, and find out what caused the drain to collapse.
The bottom line
There’s no fixed price for a collapsed drain. The repair method sets the cost, and what the camera finds sets the method. Find the cause first, and a feared dig can often become a cheaper no-dig repair.
