What Is Pipe Replacement & Relining — and When Do You Need It?

Your property’s pipework does an enormous amount of work, day in and day out. Over time — particularly in older London properties where original lead, iron, or clay pipes may still be in place — that pipework degrades. It corrodes, cracks, becomes blocked with scale, or simply reaches the end of its serviceable life.

There are two main ways to address failing pipes: replacement and relining. The right approach depends on the condition of the pipes, their location, your property type, and the scale of the problem.

Pipe replacement involves removing the old pipework entirely and fitting new pipes in its place. It’s the right solution when pipes are too badly damaged to reline, when the pipe material itself is a concern (older lead or iron pipework, for example), or when access is straightforward enough to make excavation practical.

Pipe relining — sometimes called no-dig pipe repair — involves inserting a flexible lining into the existing pipe and inflating it against the pipe walls, where it cures in place to form a smooth, durable new inner surface. It’s ideal for underground or inaccessible pipes where excavation would be highly disruptive or expensive, and it can add decades of life to a pipe that still has its basic structure intact.

Both methods are used as part of our wider installation services, and in many cases the right solution involves a combination of the two. Our engineers will assess your pipework properly and give you an honest recommendation before any work is agreed.

Our Pipe Replacement & Relining Services

Full Pipe Replacement

For pipework that has failed beyond the point of relining — or where the pipe material itself needs changing — full replacement is the correct solution. This covers supply pipes bringing fresh water into your property, waste pipes carrying water away, and internal distribution pipework throughout the building.

Full pipe replacement is particularly relevant for older London properties still running on original lead pipework, which presents a health concern, or on ageing iron pipes that have corroded significantly. It’s also the appropriate choice when a pipe has collapsed entirely or when the route needs to change as part of a wider renovation.

We carry out replacement work as neatly and efficiently as possible, reinstating any disturbed surfaces on completion. Where access can be managed through existing service routes rather than new openings, we’ll always take that approach first.

Drain Pipe Relining (No-Dig)

Drain pipe relining is one of the most significant advances in modern plumbing, and it’s particularly well-suited to the conditions found in many London properties — older homes with underground drainage runs beneath gardens, driveways, or outbuildings, where digging up the ground would be highly disruptive and expensive.

The relining process typically begins with a CCTV drain survey to assess the condition of the pipe and confirm that relining is appropriate. The pipe is then cleaned using high-pressure water jetting to remove any debris, scale, or root ingress. A resin-impregnated liner is then inserted and inflated against the pipe walls, where it cures to form a smooth, jointless inner surface that is highly resistant to root ingress and corrosion.

The result is a pipe that functions as well as — and in many respects better than — a new pipe, without the need for excavation. Relining is suitable for clay, concrete, cast iron, and plastic pipes, and the completed lining carries a long-term guarantee.

Supply Pipe Replacement

The supply pipe connects your property to the mains water supply and runs underground, often beneath your garden or driveway. If this pipe is leaking, corroded, or undersized for your current water usage, it will affect water pressure throughout your property.

Supply pipe replacement involves excavating to reach the pipe, replacing it with a modern polyethylene pipe that is flexible, durable, and resistant to corrosion, and reinstating the surface. If water pressure issues have been a persistent problem in your property, the supply pipe is often one of the first things we investigate.

Internal Pipework Upgrade

Many older London properties have internal copper or iron pipework that is performing poorly — corroded internally, scaled up, or suffering from pinhole leaks that are difficult to trace. Where a full internal pipework upgrade is the right answer, we can carry out a systematic replacement of your distribution pipework in sections or as a complete package.

This type of work is often carried out alongside a wider renovation, bathroom fitting, or kitchen refit. If you’re having your bathroom fitted or carrying out significant building work, it’s an ideal opportunity to address ageing pipework at the same time rather than face disruptive repairs later.

Why Getting Pipework Right Matters in the UK

Pipework isn’t the most glamorous part of a building, but it’s one of the most consequential. Poorly executed pipe replacement — using substandard materials, incorrect pipe sizing, or inadequate jointing — can lead to leaks, water pressure problems, and significant damage that is expensive and disruptive to put right.

In the UK, plumbing work in domestic properties must comply with the Water Supply (Water Fittings) Regulations 1999, which set out requirements for the materials and methods used in pipework connected to the mains supply. For certain types of work, notification to the water authority is required.

Supply pipe replacement in particular must use approved materials — the use of lead pipe for new supply connections has been prohibited for decades, and the replacement of existing lead supply pipes is actively encouraged by water authorities. If your property still has a lead supply pipe, replacing it is strongly advisable, and in some areas water companies offer a contribution towards the cost.

All pipework carried out by Catalyst Home Services is done using approved materials and methods in compliance with the relevant regulations. Our engineers are experienced in working with the full range of pipe types found in London’s varied housing stock — from Victorian-era clay drainage to modern plastic supply systems. See our licences and certifications for full details of our qualifications.

Who We Work With

Homeowners dealing with repeated leaks, low water pressure, or the aftermath of a burst pipe often need pipework assessed and replaced as part of a comprehensive fix. We work with homeowners across London to identify the root cause and carry out lasting repairs.

Landlords and letting agents have a legal obligation to maintain pipework in good repair under the Landlord and Tenant Act 1985. Failing pipework that affects water supply or causes damp is not something that can be deferred. Our residential AMC service gives landlords the reassurance of regular inspections and planned maintenance, reducing the likelihood of emergency failures.

Commercial property owners and facilities managers face particular challenges when pipework fails in a live environment — the disruption to operations, the potential for damage to stock or equipment, and the liability implications. Our commercial plumbing team is experienced in managing complex commercial pipework projects with minimal disruption, and our commercial AMC plans cover ongoing maintenance.

Developers and builders carrying out renovations, conversions, or new build projects in London rely on us for pipework that is correctly specified, properly installed, and compliant from the outset. We can be involved from the design stage through to final commissioning.

How the Process Works

Here’s what to expect when you get in touch with Catalyst Home Services about pipe replacement or relining.

Step 1 — Initial contact. Call us on +44 7400 265421 or book a plumber online. Tell us what you’ve noticed — whether that’s a known pipe failure, signs of a leak, persistent pressure problems, or simply old pipework you want assessed. We’ll arrange a visit at a time that suits you.

Step 2 — Survey and diagnosis. Our engineer will inspect your pipework, carry out any investigation needed (including CCTV survey of drainage pipes where appropriate), and identify the extent of the problem. We’ll explain clearly what we’ve found and what your options are.

Step 3 — Clear, itemised quote. Before any work begins, you’ll receive a written quote covering exactly what will be done, what materials will be used, and what the total cost will be. No hidden additions, no vague estimates.

Step 4 — Work is carried out. Our engineers get on with the job using proper materials and methods. We work as neatly as possible, protect your home or premises during the work, and keep you informed if anything changes along the way.

Step 5 — Testing and sign-off. On completion, all pipework is pressure-tested and flow-checked before we leave. For drainage relining, a post-lining CCTV inspection confirms the quality of the completed work.

Step 6 — Reinstatement and handover. Any surfaces disturbed during the work are reinstated, and we provide any documentation required for compliance or insurance purposes. We’ll walk you through what was done and answer any questions before we go.

Frequently Asked Questions

What is pipe relining and how does it work?

Pipe relining — sometimes called no-dig or trenchless pipe repair — involves inserting a resin-impregnated flexible liner into a damaged pipe and curing it in place to form a smooth, hard inner surface. The existing pipe acts as a host for the new lining, meaning the pipe can be repaired without excavation. It’s suitable for drainage pipes, sewer pipes, and in some cases supply pipes, and is particularly popular in London where excavating beneath driveways, gardens, or outbuildings would be highly disruptive. A CCTV drain survey is usually the first step to confirm that relining is appropriate.

How long does relined pipe last?

Quality pipe relining, carried out properly using a certified lining system, typically carries a lifespan of 50 years or more. The cured lining is smooth, jointless, and highly resistant to root ingress and corrosion — in many respects more durable than the original pipe it sits inside. We use reputable lining systems and carry out a post-installation CCTV inspection on completion to verify the quality of the work.

Is pipe relining cheaper than replacement?

In many cases, yes — particularly where the pipe is underground or in an inaccessible location. The cost of excavation, reinstatement of surfaces, and the disruption involved in open-cut pipe replacement can significantly exceed the cost of relining. However, if the pipe structure has collapsed, or if the pipe material itself needs to change, replacement may still be the right answer. We’ll give you an honest assessment of both options and their relative costs.

Do I need to notify anyone before replacing my supply pipe?

For supply pipe replacement — the pipe connecting your property to the mains — you may need to notify your water company, depending on the location and scale of the work. This is handled by your plumber as part of the job. All supply pipe work carried out by Catalyst Home Services uses approved materials and methods in compliance with the Water Supply (Water Fittings) Regulations 1999.

How do I know if my pipes need replacing or relining?

Common signs include persistent or unexplained leaks, low water pressure throughout your property, discoloured water, damp patches on walls or ceilings with no obvious cause, or a CCTV drain survey that reveals cracks, root ingress, or significant corrosion. If you’ve noticed any of these issues, it’s worth having a professional assessment. We’ll tell you honestly what we find and what we recommend.

Can you replace lead pipes in my property?

Yes, and we strongly recommend doing so if your property still has a lead supply pipe. Lead pipework was common in properties built before the 1970s, and while the risk from lead in drinking water is highest in soft water areas, it is advisable to replace it regardless. In some parts of London, water companies contribute towards the cost of supply pipe replacement as part of a lead replacement scheme — we can advise on this during the survey. Replacement is carried out using modern polyethylene pipe that is durable, flexible, and fully approved.

How long does pipe replacement take?

A straightforward supply pipe replacement typically takes one day. More extensive internal pipework replacement, or drainage relining projects requiring significant pipe preparation, may take two to three days depending on the scale and access conditions. We’ll give you a clear timeframe as part of your written quote so you can plan accordingly.

Will you make a mess in my garden or driveway?

We take reinstatement seriously. Where excavation is necessary — for supply pipe replacement, for example — we take care to minimise the area disturbed, protect surrounding surfaces, and reinstate properly on completion. In many drainage cases, relining avoids excavation altogether. If you’re concerned about specific surfaces — a new driveway, paving, or landscaping — tell us during the survey and we’ll factor that into our approach.
