How much does drain relining cost?

Drain relining typically costs £70 to £150 per metre, depending on pipe diameter, access, and condition. A single patch repair for a localised crack usually costs £200 to £400. Full relining of a typical residential drain run costs £500 to £1,500. We include a CCTV survey to diagnose the problem, and we quote fixed prices before any work starts.

What is drain relining?

Drain relining - also called no-dig repair or CIPP (cured-in-place pipe) lining - creates a new pipe inside your existing damaged pipe. A flexible liner coated with resin is inserted into the drain, positioned over the damage, then inflated and cured to form a smooth, seamless new surface. Once hardened, it's as strong as a new pipe and should last for decades.

What's the difference between patch repair and full relining?

Patch repair fixes a specific area of damage - a single crack, a displaced joint, or a small hole. It's quicker and cheaper when damage is localised. Full relining covers the entire length of the pipe, creating a continuous new surface. It's better when there are multiple defects, widespread cracking, or root damage throughout the pipe.

Can all damaged drains be relined?

Most can, but not all. Relining works well for cracked pipes, joint displacement, root damage, and holes caused by corrosion. It's not suitable for pipes that have completely collapsed (there's no structure left to line), pipes with severe changes in diameter, or very old pitch fibre pipes that have deformed. We'll assess with CCTV and tell you honestly whether relining will work for your situation.

How long does drain relining last?

A properly installed drain liner should last 30 to 50 years - often longer than the original pipe. The resin materials are resistant to chemical erosion from household products, root penetration, and general wear. We guarantee our relining work for 10 years, but you should expect it to last much longer.

Is drain relining better than replacing the pipe?

For most situations, yes. Relining costs less, causes minimal disruption, and the finished result is just as durable as a new pipe. You avoid digging up gardens, driveways, and patios - and the reinstatement costs that come with excavation. However, if your pipe has completely collapsed or has serious structural issues, replacement may be the only option.

How long does drain relining take?

Most residential relining jobs are completed in a single day. The actual lining process takes a few hours, then the resin needs time to cure - usually 2 to 5 hours depending on temperature. Larger jobs or full-length relining of longer pipe runs may take a day and a half. Your drains are typically usable again the same day.

Do I need a CCTV survey before drain repair?

Yes - and we include one with every repair job. A CCTV survey shows exactly what's wrong, where the damage is, and how extensive it is. Without this, any repair is guesswork. The survey also confirms whether relining is suitable or if excavation is necessary, so you get the right solution first time.

Will I need to dig up my garden for drain repairs?

Often, no. No-dig techniques like relining and patch repair can fix most drain problems without excavation. However, if your pipe has completely collapsed, has severe structural damage, or needs rerouting, excavation may be necessary. We'll always explore no-dig options first and only recommend digging when it's genuinely the best solution.

What are the signs I need drain repairs?

Common signs include slow-draining sinks, baths, or toilets, recurring blockages that keep coming back, bad smells from drains, damp patches on walls or floors, wet or sunken areas in your garden, and visible cracks or damage to manholes. If you're experiencing any of these, a CCTV survey will identify whether repairs are needed.

Who is responsible for drain repairs?

If the drain is within your property boundary and serves only your property, it's your responsibility. Shared drains and lateral drains (the section connecting your property to the public sewer) became the responsibility of water companies in 2011. If you're not sure where the boundary lies, we can help identify this during our survey.
