The Southampton to London Pipeline (SLP) project is replacing 90km of the underground fuel pipeline between Boorley Green, Hampshire and the West London Terminal storage facility in Hounslow.

This is a replacement for the existing aviation fuel pipeline, which has been in place since 1972.
We will inform local communities two months before any works commence in their area.
Once installed, the replacement pipeline will be buried and will be a quiet neighbour.

Construction works to install the replacement pipeline began in late 2021 and are estimated to be completed in 2023. It is a complex engineering challenge and we’re working hard to keep construction impacts to a minimum. We are working to minimise the time we spend in specific locations within our two-year programme and once the pipeline is buried, it’s a quiet neighbour. 

Prior to installation, we released a local area specific timeline for installation that we submitted to the ten planning authorities along the 90km replacement pipeline route, alongside a suite of management documents. Following the thorough examination of our proposals as part of the Development Consent Order (DCO) application, these documents were subject to the approval of the local authorities as per the requirements of our DCO and govern how we conduct installation in their area. 

On this site you’ll find more about how we are installing the pipeline and what techniques and technologies we are using. Take a tour of our interactive map to find out about installation in your area.
