How we’re performing

The scale of HS2 gives us a unique opportunity to raise health and safety standards across the industry, working with our partners, using evidence-based solutions and harnessing innovation to better protect people.

We’ve introduced performance measures across the programme so we can build on successes and address areas where we can improve. This will promote consistent working and evidence to drive up standards year-on-year.

As with all major construction programmes, health and safety risks increase in line with the volume and intensity of work. In 2020 – 2021, we reviewed our Health and Safety Performance Indicators (HSPIs) and assessed our position through benchmarking against other major programmes and organisations including Crossrail, Thames Tideway, EDF Energy, Openreach, Highways England and the North London Heat and Power Project. We wanted to understand the health and safety measures they report on more fully and this resulted in some changes to HSPI indicators for 2021 – 2022.

Our Health and Safety Performance

We set out to achieve improved standards in health and safety performance, learning and building on megaprojects that have gone before us and leaving a positive legacy for future projects.

Our Health and Safety Performance Indicators (HSPI) measure six areas including leading and lagging performance, occupational health and wellbeing, training, supervision, engagement and assurance. Each area has its own scoring criteria, but they are all measured on a scale of 0 to 3, categorised as follows:

  • Underperforming
  • Performing well
  • Exceeding target

The average of the six individual HSPIs provides our overall HSPI score, which gives us a programme-wide picture of how we’re managing health and safety performance.

Our programme HSPI target for HS2 started at 1.20 in 2018. In line with our strategic ambition, we have continuously revised and set the bar higher, moving to our target of 2.20. In 2021 – 2022, we missed our target of 2.20. However, in 2022 – 2023, we’ve exceeded our target, achieving 2.48. In previous years, we have achieved or exceeded our target.

Our performance to date

In 2022 – 2023, nearly 60 million hours were worked – and since 2016, nearly 200 million hours have been worked. We have seen rapid growth and a change in delivery focus over the years from early works activities, such as utility diversions, demolitions and ecology, to main works activities including major earthworks, tunnelling and lifting activities.

Against this background, many of our measures are industry leading, such as our Accident Frequency Rate (AFR), and other measures including Injury Weighted Index (IWI), Lost Time Injury Frequency Rate (LTIFR) and All Accident Frequency Rate (AFR) show strong performance despite the rapid pace and volume of delivery progress. Our performance across the programme demonstrates our commitment to health and safety.

We always strive to set the bar higher for HS2. As we mobilise further parts of our programme over a geographically wide area, we will not lose focus on our performance.

In the next three years, we predict we’ll work about 200 million hours – the same amount worked in the last eight years on the project.

Our health and safety performance

  • 5.65 Injury Weighted Index

    There were four RIDDOR reportable incidents in 2016/17 associated with GI works, which combined with lower hours worked, led to the spike in this year. There were zero RIDDOR reportable incidents in 2017/18 which led to the large drop.

  • 0.06 Accident Frequency Rate (AFR) RIDDOR

    The AFR (RIDDOR rate) is currently 0.06, which is industry leading. There has been one incident categorised as life changing during the HS2 project to date. This was November 2022 on our Main Works Civils Contract (MWCC).

  • 0.16 Lost Time Injury Frequency Rate (LTIFR)

    As the work has increased and risk profile has changed, the number of Lost Time injuries has increased. However, it has remained constant for the last two years.

  • 0.76 All Accident Frequency Rate (AAFR)

    Despite an increase in hours, our All Accident Frequency Rate has remained fairly constant since 2017, with a slight increase in 2022 – 2023.

  • 0.22 High Potentials (HiPos)

    As hours have increased year on year the number of High Potentials has also increased due to workload and risk of activity. This displays a strong reporting culture. High figures in early years are due to low hours worked.

  • 0.97 No harm/no loss (Near miss)

    As hours have increased year on year the number of No harm/no loss has increased. Initially the rate, based on hours worked was higher, but as the number of hours has rapidly increased it has seen the rate fall.
