The programmes will run from 2021-2026 and will be worth £700m in the southern region of England, including London, and more than £200m in Scotland.

Each area will be broken up into several sub-areas where one contractor will be selected to deliver the works.

The main task will be to replace underground cast iron gas mains and steel service pipes with polyethylene pipework.

The majority of the mains to be abandoned and renewed will be in the diameter range 3” to 8” with a significantly smaller quantity in the diameter range 9” – 12”.

In the south, the mains are located in predominantly urban locations including London (South of the River Thames), the South and South East of England and operate at pressures up to 2 bar.

Most replacement mains will be constructed using live or dead mains insertion techniques in order to reduce reinstatement costs and increase productivity. The works will also include pricing options for open-cut mainlaying.
