Collapsed Drain Repair Cost: What You'll Pay in 2026

A collapsed drain repair in the UK typically costs around £850, according to MyJobQuote's August 2026 price guide, with a small patch repair at the bottom of the range and a fully collapsed pipe that needs digging out at £1,000 to £3,000 or more. Our drain repairs start from £250 + VAT, and we give you a fixed price once a camera has shown exactly what is broken and where. If the collapse is in a pipe shared with neighbours or beyond your boundary, it is usually the water company's to repair, not yours.

This guide covers what you can expect to pay, what pushes the cost up, who is responsible and what insurance pays for. If you are not yet sure the drain has collapsed, start with the signs of a blocked or collapsed drain.

How much does a collapsed drain repair cost?

Around £850 for a typical job. The figures below come from MyJobQuote's collapsed drain repair cost guide, updated 27 August 2026, which says its data comes from real quotes given by UK tradespeople. They are national market prices from other firms, not our prices.

A second guide gives a wider spread. Less.co.uk's drainage cost guide, updated June 2026, puts excavation and drain replacement at £1,000 to £5,000 or more and a typical full-run reline at £1,500 to £4,000. It gives an average of £2,600 in the Midlands for a typical drain repair including a survey and a single reline, which it lists as level with the national average.

What do we charge to repair a collapsed drain?

Our drain repairs start from £250 + VAT. We don't quote a collapsed drain over the phone, because the price depends on things nobody can see from the surface. Instead:

1. We look first. A CCTV drain survey, from £149 + VAT, shows the type of damage, its exact position, its length and the pipe material.
2. We quote a fixed price. The quote is based on the footage, and we agree it with you before any work starts.
3. We repair and re-check. We carry out patch repairs, drain relining and excavation, and every repair comes with a 12-month guarantee.

There's no call-out fee. If the camera shows the damage is in a pipe the water company is responsible for, we tell you, so you don't pay for a repair that isn't yours.

What drives the cost of a collapsed drain repair?

Five things decide most of the bill: how deep the pipe is, how much of it is damaged, which repair method it needs, what sits on top of it and what it is made of.

Extras catch people out. MyJobQuote lists jetting before the repair at £100 to £250, tree root removal at £100 to £250, and a post-repair camera check at £100 to £200 where it isn't included. Ask whether each one is in the price.

Pitch fibre deserves its own mention. Pipes laid between the 1950s and 1970s were often pitch fibre, which deforms and blisters with age, and many insurers won't pay to repair it. A survey report will name the material. Our guide to pitch fibre pipes explains the options.

Work in the road costs more because digging up a street needs the highway authority's permission. Under section 50 of the New Roads and Street Works Act 1991, a street works licence from the street authority is what permits a person to place or repair a pipe in a street, including breaking the street open. In practice, if the collapsed section is under the pavement or road outside a house connected to the sewer before July 2011, it is very likely to be a lateral drain that the water company now owns.

Patch, reline or excavate: which will you be paying for?

The survey decides. A patch suits one crack or open joint in an otherwise sound pipe. Relining suits damage spread along a run that still holds its shape. Excavation is needed where the pipe has actually collapsed, is badly deformed or has dropped out of line. As a rough rule, the further down that list your drain is, the higher the bill.

We compare the three methods in detail, including how long each lasts and when lining isn't suitable, in drain relining vs excavation.

Who pays for a collapsed drain?

You pay for a drain that serves only your property and sits inside your boundary. The water company pays for pipes shared with neighbours and for the length of your own pipe that runs beyond your boundary to the public sewer.

That split dates from 1 October 2011. Defra's guidance on the private sewers transfer explains that on that date, privately owned sewers and lateral drains that drained to a public sewer on 1 July 2011 transferred to the sewerage companies. It defines a lateral drain as one that serves a single property but lies beyond its boundary. The legal instrument is the Water Industry (Schemes for Adoption of Private Sewers) Regulations 2011.

So before you pay anyone to repair a collapsed drain:

• Ask the neighbours. If they have problems too, the collapse may be in a shared pipe.
• Check where the damage is. A survey measures the distance from the chamber, which shows whether it is inside your boundary.
• Report it if it isn't yours. Severn Trent covers most of Nottinghamshire, Derbyshire and Leicestershire and takes reports on 0800 783 4444. Anglian Water covers most of Lincolnshire.

Landlords, tenants and flats have their own wrinkles. See who is responsible for blocked drains for the full breakdown.

Does insurance cover a collapsed drain?

Often, if the pipe is yours and the damage was sudden. The Financial Ombudsman Service says most buildings policies cover damage to underground pipes and drains, but generally only pipes you are responsible for, and many don't cover pitch fibre. It lists the reasons insurers commonly give for turning claims down, including:

• the damage is gradual, or wear and tear;
• the pipe is pitch fibre;
• you aren't responsible for the pipe;
• the pipe was repaired before the insurer could inspect it.

That last one is the costly mistake. Unless sewage is coming into the house, call your insurer before agreeing any repair, and keep the survey footage, the written report and an itemised invoice. Our guide to whether home insurance covers drain damage walks through a claim step by step.

How can you keep the cost down?

Use this checklist before you agree to anything:

1. Get the camera in first. A survey costs far less than digging in the wrong place.
2. Ask to see the footage and where on the drain plan the damage sits.
3. Ask whether it's a shared or lateral pipe. If so, report it to the water company before paying.
4. Ask why a method was chosen. Excavation should be justified by what the camera shows.
5. Get the price in writing and ask whether VAT, jetting, reinstatement and a post-repair check are included.
6. Tell your insurer before work starts, unless it's a genuine emergency.
7. Ask about the guarantee and what it covers.

When to call a professional

Call a drainage engineer if a drain keeps blocking soon after clearing, if the ground over a drain has sunk, or if you have smells or damp outside with no obvious cause. These point to a broken pipe, and a broken pipe usually gets worse and more expensive the longer it is left. If sewage is backing up into the house now, see our emergency drainage page.

We carry out drain repairs from £250 + VAT across Nottingham, Nottinghamshire, Derbyshire, Leicestershire and Lincolnshire, including drain repairs in Derby and drain repairs in Leicester. Our engineers work 7 days a week from 6am to 8pm, with emergency call-outs 365 days a year and no call-out fee. Call 07300 600 950 or book online.
