Lead pipe replacement in Macclesfield
In short
Homes built after 1970 will not have lead supply pipes; homes built before it may. Replacement means running new blue MDPE from the boundary into the property and re-making the connection inside. United Utilities will renew the section from the water main to your boundary free of charge under their lead pipe scheme — the run inside your boundary is the homeowner's.

Signs you need this
- Property built before 1970 with an original supply pipe
- Dull grey, soft, unthreaded pipe at the stopcock
- Swollen, bulged or previously patched pipework near the entry point
- Poor flow at the kitchen tap on an older property
- A water test showing lead present
Lead was standard for water service pipes for a very long time, and it only stopped being used in this country around 1970. Identifying it is straightforward: lead pipe is dull grey, soft enough to mark with a coin, unthreaded, and it gives a dull thud rather than a ring when tapped. It is usually visible where the supply enters the property, often near the internal stopcock.
There is a specifically local reason to take it seriously here. Macclesfield's water is soft — United Utilities' own supply zone data puts it at 45 mg/l in the Millbrook zone serving Hurdsfield, Tytherington, Bollington, Kerridge and Rainow, and 66 to 68 mg/l in the Lamaload and Ridgegate zones covering the town centre, Broken Cross, Weston, Moss Rose and Sutton. Their own factsheet notes that water below 100 mg/l can be more corrosive to pipes. Soft water is mildly plumbosolvent, which means it picks up more lead from a lead pipe than hard water would.
The other local factor is housing age. The town as a whole is unremarkable — around 21% of the stock is pre-1919, close to the England average — but the average hides the story. Central Macclesfield is 54.1% pre-1919 by council tax records, while Tytherington is 1.5%. If you are in the town centre or one of the older terraced streets, the odds of lead are simply much higher than they are on the newer estates.
Replacement is usually done in one continuous length of 25mm blue MDPE from the boundary stop tap into the house, either in an open trench or moled underground with minimal excavation. Inside, the new pipe is connected to the internal stopcock with the correct fittings, and any remaining internal lead — old runs to a kitchen tap, for example — is picked up at the same time, because a new supply pipe feeding an old lead internal run only solves half the problem.
The free element is worth pursuing before you spend anything. United Utilities operate a lead and common supply pipe replacement scheme which covers the communication pipe from their main to your boundary at no cost. Coordinating their work with the private side means one excavation rather than two, and it is worth asking your plumber to time the job around it.

What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your plumber has to honour it. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
How do I know if my pipe is lead?
Look where the supply enters the house, usually near the internal stopcock. Lead is dull grey, has no thread, is soft enough to scratch with a coin and sounds dull when tapped. Copper is bright or green-brown and rings; steel is magnetic and threaded.
Will United Utilities pay for the whole job?
They will replace their own communication pipe — main to boundary — free of charge under their lead pipe scheme. The supply pipe from your boundary into the house belongs to you and is at your cost. Doing both at once avoids digging twice.
