The department’s commentary
This is the department’s own commentary. It may use different prices from the table above, so its figures may not match.
March 2026
Rating: There is no comparison to financial year 24/25 Q4 as this project was added to GMPP in financial year 25/26 Q3. Compared to the previous quarter, the delivery confidence rating remains at Red as the project has not currently progressed to the 'Invite to Offer' (ITO) stage. This is primarily due to delays in OBC Approval (from September 2025) and subsequent delays to the commencement of the ITO and Negotiations phase. Ongoing delays will impact on our ability to deliver HAR2 contract awards within the timelines set out in the HAR2 published guidance
Schedule: There is no comparison to financial year 24/25 Q4 as this project was added to GMPP in financial year 25/26 Q3. Compared to Q3, the end date remains the same. This is primarily due to the following factors: If we can sign contracts with projects by -financial year 26/27 Q3, the HAR2 end date of 31/12/2041 would still apply. However, we are unable to produce meaningful baseline and forecast dates until we have clarity on ITO start and therefore the HAR2 end date may be subject to change.
Cost: WLC are £9427.02m in Real Prices 24/25 as calculated by NISTA based on £9061m (DESNZ Nominal Pricing)
