Phase 1 HS2 Construction Timeline | When Will Your Skills Be Needed?

As the UK’s largest infrastructure project, HS2 naturally provokes many questions in the contractor community. Our social media channels have been inundated with requests from our candidate community asking if and when their skills will be needed to work on the project. This blog aims to answer these queries, outlining the HS2 construction timeline for Phase One, illustrating which skills will be needed when, from 2017 until 2026.

The HS2 construction timeline set out by HS2 and the UK Government, suggests that the Phase One route (London to Birmingham) will take approximately 8 years, from site clearance to railway installation. This will be followed by a period of testing and commissioning before the first services start running in 2026.

Interestingly, the timeline shows that HS2 Phase One will only experience active construction for approximately two years prior to railway installation (in areas where there are no major structures).

Read on to find out when and where your skills will be needed on HS2. The key phases of the HS2 construction timeline are outlined below:hs2 construction timeline
