TPI forecast
Cost pressures are rising again
The biggest change in our latest TPI forecast figures is in 2026. We now forecast TPI of 5.0%, up from 3.06% previously. This reflects rising energy costs, supply chain disruption and trade price increases following the conflict in the Middle East.

2019-2028
Recent inflation data suggests that price pressures across the wider economy have eased. But the outlook has become more uncertain. Higher energy prices and disruption to global trade could still increase inflation in the months ahead.
Construction is also facing its own challenges. Labour shortages remain in some areas, manufacturers are producing fewer key materials, and logistics costs remain volatile.
Together, these factors are expected to keep construction inflation above CPI through the forecast period.
At the same time, competition for work remains strong. Many contractors are absorbing some cost increases rather than passing them on in full to clients. This is helping to keep tender prices lower than they might otherwise be.
We’ve reduced our forecasts for 2027 and 2028 slightly compared with our previous outlook. This reflects expectations of slower growth in construction activity over the coming years.
The picture is broadly similar across the UK, although there are some regional differences. Certain scheme types, such as build-to-rent, that can be difficult to make financially viable in London are gaining greater traction elsewhere in the UK, helped by lower land prices. Growing developer interest is supporting activity, while there is enough competition between contractors to keep cost increases under control.
Looking beyond the forecast
Although inflation is well below the peaks seen in 2022 and 2023, risks remain.
Earlier expectations that lower inflation would lead to further interest rate cuts are now being pushed back. The conflict in the Middle East has increased uncertainty about how quickly inflation will fall and when borrowing costs might reduce.
There is also a longer-term risk for the sector. In some cases, the cost of labour, materials and energy is rising faster than tender prices. If contractors continue to absorb these costs to remain competitive, pressure on margins could increase.
What this means for organisations
Organisations should not assume that lower inflation means lower project risk.
The factors driving construction costs are often different from those affecting the wider economy. Cost pressures can vary significantly between sectors and projects.
Regular market testing, access to current cost data and early engagement with the supply chain will help organisations make informed decisions and maintain budget certainty.
