Lead Pipe Replacement in London
Lead pipes are poisonous — and thousands of London homes still have them. Meridian Plumbing specialises in safe, complete lead pipe removal and replacement across all London boroughs.
Lead is a toxic heavy metal. When lead pipes corrode, they release lead particles directly into your drinking water. According to the World Health Organization and UK health authorities, there is no safe level of lead exposure. The effects are irreversible, especially in young children, where even small amounts can cause permanent neurological damage, learning difficulties, and developmental delays. Pregnant women are also at serious risk — lead crosses the placental barrier and can harm unborn babies.
If your home was built before 1970, do not wait. Contact Meridian Plumbing for a site visit today.
Why Replace Your Lead Pipes?
Many London properties built before the 1970s still have lead supply pipes connecting them to the water mains. Lead dissolves into drinking water over time and poses serious health risks, particularly for young children, pregnant women, and the elderly. There is no safe level of lead exposure.
Replacing your lead pipes is the only permanent solution. Meridian Plumbing specialises in complete lead pipe replacement across London — from the boundary stop tap to your kitchen tap, and everything in between.
Our Lead Pipe Replacement Process
We make the process straightforward and hassle-free. Every job starts with a no-obligation site assessment where we inspect your existing pipework, explain your options, and provide a written quote.
How Do I Know If I Have Lead Pipes?
Lead pipes are dull grey in colour and feel soft — if you scratch the surface with a key or coin, you'll see shiny silver metal underneath. They're typically found where the supply pipe enters your property, often under the kitchen sink or in the cellar. If your property was built before 1970, there's a high chance some or all of your supply pipe is lead.
Not sure? Meridian Plumbing offers no-obligation site assessments across all London boroughs. We'll inspect your pipework and let you know exactly what you're dealing with.
Health Risks of Lead Pipes in Detail
Lead is a cumulative toxin — it builds up in the body over time and is not easily eliminated. The health effects include:
- Children: Impaired cognitive development, reduced IQ, learning difficulties, behavioural problems, and hearing loss — even at very low exposure levels.
- Pregnant women: Lead crosses the placenta and can cause miscarriage, premature birth, low birth weight, and neurological damage in newborns.
- Adults: Increased blood pressure, kidney damage, reproductive problems, and increased risk of heart disease with long-term exposure.
The UK government and WHO both confirm there is no threshold below which lead is considered safe. The only solution is to remove the source.

Lead is a highly toxic heavy metal with no safe exposure level. When lead pipes corrode, they leach lead directly into your drinking water. Even tiny amounts cause irreversible damage — especially in children under 6 where it impairs brain development, and in pregnant women where it can harm the unborn child. The WHO, UK Government, and NHS all agree: lead pipes must be replaced.
Look where the water pipe enters your home (under the kitchen sink, in the cellar, or at the stop tap). Lead pipes are dull grey, feel soft, and reveal bright silver when scratched. Homes built before 1970 are most at risk. If unsure, call Meridian Plumbing to arrange a visit.
Thames Water splits responsibility for lead pipes at your property boundary. The communication pipe — running from the water main to your boundary — is Thames Water's responsibility. Under their lead pipe replacement programme, Thames Water will replace this section at no cost to you. The supply pipe — running from your boundary into your home — is your responsibility as the homeowner, and this is the section Meridian Plumbing replaces. We strongly recommend applying to Thames Water first so both sections are replaced together, giving you a fully lead-free supply from main to tap. We guide you through the Thames Water application and coordinate our work around their schedule at no extra charge.
Most jobs are completed within a single day. If the pipe runs under your driveway or garden, we can often use moling (trenchless technology) to replace it without any digging at all — saving time and surface reinstatement costs.
Not necessarily. Meridian Plumbing specialises in moling — a trenchless method of pipe replacement that installs a new pipe underground without excavation. This is particularly useful when replacing lead pipes that run under paved surfaces. We assess each job individually and always recommend the least disruptive method.
