Professional Water Supply Pipe Renewal Services in London

If you suspect that your property’s water supply pipe may need repair or replacement, the team at Greater London Water is here to help you find the most effective and affordable solution. Whether you’ve noticed a leak, are dealing with low water pressure, or are planning a renovation, renewing your old water supply pipe — especially if it's made of lead — can significantly improve your water quality and system performance.


Low Water Flow or Pressure

The condition of your private water supply pipe plays a major role in how much water reaches your taps. If the pipe is damaged, corroded, or undersized, it can cause poor flow or fluctuating pressure. Several factors may contribute to this, including:

 

• A narrow internal pipe diameter
   

• Corrosion inside older iron or lead pipes
   

• Increased demand for water during peak times
   

• The overall length of the supply pipe
   

• Leaks or fractures within the pipe
   

• Low pressure in the local water main
   

• The number and condition of components like ferrules, stop taps, meters, and bends
   

• Obstructions such as grit, a partially closed valve, or internal damage

​

Replacing your water supply pipe with a modern, compliant alternative can resolve these issues and restore proper flow. 


Lead Water Supply Pipes
 

If your property was built before 1970 and hasn’t been updated, there’s a strong chance that the water supply pipe is made of lead.

​

For homes with lead piping, it’s often recommended to run the cold tap briefly before drinking, especially after the water has been standing — such as overnight or while away — as this can reduce lead levels by flushing stagnant water from the pipe.

​

It’s also important to avoid drinking from the hot tap, as hot water dissolves lead more readily than cold, increasing the concentration.

While water suppliers like Thames Water carry out regular testing, the legal limit for lead under The Water Supply (Water Quality) Regulations 2016 is 10 micrograms per litre — yet medical experts agree that no level of lead exposure is considered truly safe.

If you’re concerned about lead levels in your drinking water, or you’re planning to modernise your plumbing system, replacing your lead water supply pipe is a smart, preventative measure.

 

Renovating your property?
 

If you’re carrying out renovation work — particularly in areas where plumbing is exposed — it’s the perfect time to consider upgrading your water supply pipe.

Replacing an old lead water supply pipe during renovations can save time, money, and disruption later. This is especially relevant if you're replacing or resurfacing your driveway — doing the pipework now means you won’t have to dig it up again in future for repairs or upgrades.
