HS2 Ltd published a preliminary market engagement notice on 12 August, asking the supply chain for views on a partnering arrangement that would run from 1 October 2027 to 30 September 2037. The notice covers project and programme management, commercial delivery, and technical and engineering capability, as the organisation firms up how it wants to procure the next phase of the railway.

That next phase is the point. HS2 has said it is transitioning from major civil engineering works towards railway systems installation, integration, testing and commissioning. All 46 miles of twin-bore tunnel between Old Oak Common and Birmingham are now excavated, around 108 million cubic metres of earthworks are done, and 177 bridges and viaducts are under construction. The heavy earthmoving phase that has employed tens of thousands of groundworkers, civil engineers and plant operators over the past five years is entering its final stretch. What replaces it is track, signalling, power and communications systems, then dynamic testing and trial running.

HS2 Ltd is running the market engagement to test how the industry wants this parcelled out (as one long-term partnership or split into more competed packages) before publishing a tender notice, provisionally pencilled in for April 2027. Responses are due by 9 October.

Why it matters for the market

Big infrastructure programmes tend to be read as a single hiring event, but they are really a sequence of different hiring events wearing one project name. The civils-heavy workforce that built the tunnels and viaducts is not the same workforce that installs and commissions railway systems. Around 30,000 people currently work on HS2 in total, across engineering, construction and design, and HS2 has been explicit that the systems phase will generate its own wave of opportunities over the next decade rather than simply running down the current one.

A 10-year partnering arrangement, if it proceeds in that form, also changes the shape of the roles on offer. Framework and partnership structures tend to favour candidates who can commit to a long programme and who understand collaborative or alliance-style contracts, over those chasing the next short-term contract role.

What it means for your career

If your background is groundworks, earthworks or structures, HS2's civils demand has likely peaked. That is not a reason to panic, but it is a reason to look at where that experience travels next: other live programmes such as Sizewell C, the Thames Water and Yorkshire Water AMP8 investment rounds, or the next tranche of Hospital 2.0 schemes are all still in their civils-heavy phase and will want people who have just finished cutting their teeth on HS2's earthworks and structures packages.

If you have systems, rail electrification, signalling, or testing and commissioning experience, this is worth watching closely. Electrical test and commissioning engineers are already being recruited for HS2 delivery, and a formalised 10-year systems partner arrangement would mean sustained demand for commercial managers, project controls and engineering management roles who understand systems integration contracts rather than earthworks packages. Quantity surveyors and commercial staff with rail systems or M&E experience, in particular, are in a thinner part of the market than general civils QS talent, and that scarcity tends to show up in rate and permanency of role well before it shows up in headline job adverts.

Worth tracking the tender notice due around April 2027: whoever wins that partnering slot will be building out a delivery team from scratch, and that is usually where the best-paid early moves sit.
