Lead Pipe Replacement in Sussex & Surrey
Remove old lead supply pipes and install a new MDPE main — usually in a single day, with no trench across your garden or driveway.
Why lead pipe replacement matters
Thousands of homes across Sussex and Surrey still have original lead supply pipes — especially those built before 1970. Lead is a known health risk, particularly for babies, young children and pregnant women. The only permanent solution is to replace the pipe entirely.
At Grange Plumbing, we specialise in replacing lead pipes using trenchless moling. Two small pits, a new MDPE main pulled through underground, and your garden or driveway stays untouched. Most jobs finish in a single day.
The risks of lead in drinking water
Child development
Lead exposure in babies and young children can affect brain development, behaviour and IQ even at low levels. Pregnant women should also avoid lead-contaminated water.
Legal limit
The UK legal limit for lead in drinking water is 10 micrograms per litre. Water that has stood in a lead pipe overnight can easily exceed this.
No safe level
The World Health Organisation states there is no known safe level of lead exposure. The only permanent fix is to remove the lead pipe entirely.
Aging infrastructure
Pre-1970 homes across Sussex and Surrey commonly still have original lead supply pipes. If you've never replaced yours, it may still be lead.
Why choose Grange Plumbing for lead pipe replacement?
Safe drinking water
New 25mm or 32mm blue MDPE pipe is WRAS-approved for drinking water and carries zero lead risk.
No surface damage
We use trenchless moling — two small pits, no trench across your garden or driveway. Your lawn and paving stay intact.
Fixed written quote
No day rates, no hidden extras. You get one all-in price covering pipe, moling, connections, testing and reinstatement.
Water company coordination
We liaise with your water company so their side (the communication pipe) is replaced at the same time — often free of charge.
Five steps to safer water
From confirmation to clean water — typically completed in a single day.
Confirm it's lead
We inspect the pipe where it enters your property. Lead is dull grey, soft enough to mark with a coin, and often has a bulbous soldered joint at the stopcock.
Check water company schemes
We help you contact your supplier (SES Water, Southern Water, etc.) to confirm their free or subsidised lead replacement scheme.
Free site survey & fixed quote
We walk the route, check ground conditions and access, and give you a single fixed price for the whole job.
Mole the new MDPE pipe
Two small pits — one at the boundary stopcock, one at the property. A pneumatic mole pulls the new pipe through underground in a single day.
Connect, test & tidy
We connect at both ends, pressure-test to WRAS standards, flush the system and reinstate the two small pits.
Lead pipe replacement cost
Most domestic lead pipe replacements in Sussex and Surrey cost between £1,500 and £3,500 all-in. The exact price depends on the length of the run, pipe diameter, ground conditions and access.
That price includes the new MDPE pipe, trenchless moling, connections at both ends, pressure testing, chlorination and reinstatement of the two small pits. No day rates, no hidden extras.
