UK construction material prices remain roughly 39% above pre-pandemic levels in 2025, BCIS fundamentally altering project economics across the industry. After the most volatile price period in modern construction history — driven by COVID-19, the Ukraine war, and an energy crisis — steel and concrete costs have stabilised but at structurally elevated levels that continue to squeeze margins, drive insolvencies, and suppress housing delivery. The BCIS forecasts a further 15–17% increase in building costs and tender prices through 2030, Construction News with carbon border adjustment mechanisms poised to add new upward pressure on steel and cement from 2027. This report examines the full trajectory from pre-pandemic stability through crisis and into an uncertain future for the UK’s two most critical structural materials.
A decade of unprecedented price volatility for steel
Structural steel prices in the UK construction market followed a remarkably stable trajectory through the late 2010s before entering the most turbulent period in living memory. Structural steel sections held steady at around £350 per tonne through 2015–2019, with rebar at approximately £486 per tonne and plate steel at £532 per tonne in January 2019.
The COVID-19 pandemic triggered an initial demand collapse, pushing rebar down to £389 per tonne by August 2020. Construction News What followed was extraordinary. Post-lockdown demand surges collided with fractured supply chains, RICS and the BEIS Fabricated Structural Steel Price Index recorded a 52.6% annual increase in 2021 — the largest on record. Statista By January 2021, rebar had climbed to £585 per tonne; by July 2021 it reached £749 per tonne.
Russia’s invasion of Ukraine in February 2022 detonated a second price shock. British Steel imposed its largest-ever single price increase — £250 per tonne on structural sections — in March 2022, Construction Enquirer pushing large sections above £1,000 per tonne for the first time. Steel plate prices surged from £1,000 to £1,400 per tonne in a matter of days, eventually peaking at £1,692 per tonne in late April 2022. Rebar hit £1,202 per tonne the same month. Structural sections peaked at approximately £1,450 per tonne in spring 2022 Construction Enquirer — more than four times their pre-pandemic level. British Steel could only guarantee pricing for two weeks of production at the height of the crisis.
The correction that followed was sharp but incomplete. By January 2023, structural steel had fallen to around £1,000 per tonne — down 31% from the peak but still nearly three times 2019 levels. Construction Enquirer Through 2024, European steel prices continued declining to their lowest point since late 2020 at approximately USD $594 per metric tonne in Q4 2024. Tokio Marine A partial recovery brought prices to around USD $700 per metric tonne by late 2025, with British Steel imposing a £50 per tonne increase in November 2025. As of early 2026, hot-rolled coil offers from Tata Steel UK sit at around £540–620 per tonne delivered, while basic rebar trades below £675 per tonne for standard products. Jack Nicholas Group Overall, steel prices in 2025 remain an estimated 20–30% above 2019 levels.
Concrete and cement costs climbed steadily — and haven’t come back down
Unlike steel’s dramatic spike-and-retreat pattern, concrete and cement prices followed a more relentless upward trajectory. The BEIS/DBT Ready-Mixed Concrete Producer Price Index rose from a base of 100 in 2015 to 147.2 by 2023 — a cumulative 47.2% increase, with the steepest climbs occurring in 2022 (+18%) and 2023 (+16.4%). Statista Precast concrete products increased 51% between 2021 and 2025 alone.
Cement’s price behaviour reflects its energy intensity. Manufacturing a tonne of cement requires approximately 1,000 kWh of electricity, and UK industrial electricity prices sit around 50% higher than France and Germany and roughly double US rates. When the energy crisis struck in 2022, cement producers had no buffer. The Construction Leadership Council warned in July 2021 that bulk cement was “on allocation” due to unprecedented demand, and by 2022–23, cement suppliers were implementing double-digit percentage increases in rapid succession.
Current ready-mixed concrete prices average approximately £110 per cubic metre for standard C25/30 grade nationally, rising to £125–140 per cubic metre in London. Concretemath Prices range from £90 to £170 per cubic metre depending on grade, region, and delivery requirements. Bagged Portland cement retails at £5–7 per 25kg bag, equivalent to roughly £200–280 per tonne at retail.
The volume picture is even more troubling than the price picture. UK cement production fell to 7.3 million tonnes in 2024 — a 75-year low, approximately half of 1990 output. Ready-mixed concrete deliveries in 2025 dropped to 11.0 million cubic metres, the lowest in published data and roughly one-third below 2015 and 2019 levels. BCIS In Q2 2025, quarterly deliveries of just 2.7 million cubic metres represented the lowest figure since 1963. Cement imports now account for 32% of UK sales, nearly tripling from 12% in 2008, with imports valued at over £330 million in 2024. The domestic industry is simultaneously shrinking and becoming more expensive to operate.
The construction industry is buckling under cost pressures
The consequences of sustained material cost inflation have been severe and wide-ranging. Construction materials prices in 2025 were more than double their 2005 levels and 39% higher than pre-pandemic 2019, according to BCIS/DBT data. BCIS Between 2015 and 2022, UK construction material costs rose 60% — nearly double the EU’s 35% increase over the same period.
Contractor margins have been crushed to near-unsustainable levels. The average profit margin for UK Top 100 construction companies fell to just 1.7% in 2024, down from 2.7% in 2023. A Turner & Townsend study found UK construction had the lowest margins in the world at 3.9%, compared to 4.6% in North America and 6.1% in Continental Europe. ISG, the UK’s sixth-largest contractor, operated on roughly 2% operating margin before its spectacular collapse in September 2024 — a failure that left 2,200 employees redundant, Bishop Fleming over £1 billion in debt claims, Construction News and 69 public sector projects worth £1.84 billion halted mid-construction.
Insolvencies have reached alarming levels. 4,370 construction companies failed in the year to November 2023, a 76% increase from 2,481 two years earlier. Construction Index Construction accounts for roughly 14% of all UK registered businesses but 17% of all insolvencies — a disproportionate share that reflects the sector’s structural vulnerability to cost shocks. Notable collapses beyond ISG include Buckingham Group (£665 million turnover, September 2023, citing “extreme inflation”), Construction News Stewart Milne Group (January 2024), and Tolent (February 2023). Mastt Bad debt in construction escalated from £400 million at the start of 2023 to a projected £1.2 billion by end of 2024, with domino effects cascading through supply chains.
Housing delivery has suffered markedly. Net housing additions in England fell from 234,290 in 2022–23 to 208,600 in 2024–25 GOV.UK — an 11% decline in two years. Q4 2023 recorded the lowest number of new housing starts in any quarter since records began in 1978, running 52% below the ten-year average. Savills Major housebuilders saw completions plummet: Taylor Wimpey’s fell 30% in 2023 and Barratt’s dropped 28.5% in the first half. Admiral Markets The government’s target of 1.5 million new homes over five years is likely to be missed by approximately 25%.
The most visible infrastructure casualty is HS2, whose Phase 1 estimate ballooned from £37.5 billion Institute for Government to up to £67 billion. HS2’s chair told Parliament in January 2024 that construction inflation had run at 27% over three years, with steel up 47%, rebar up 53%, and concrete up 48%. Inflation alone added £8–10 billion to the estimate. Construction News The northern and eastern legs were scrapped entirely, primarily on cost grounds.
How the industry is adapting to a new cost reality
The era of routinely deleting fluctuation clauses from construction contracts appears to be over. The Construction Leadership Council has urged inclusion of fluctuation provisions, and the JCT has published guidance on managing price inflation through its three fluctuation options. As one legal firm noted, “the Employer luxury of a fully fixed price construction contract will be largely reserved for low-risk projects of short duration.” Ashfords LLP Contractors increasingly demand price escalation clauses linked to BCIS or DBT indices, with quarterly material cost reviews becoming standard practice.
Value engineering has become essential rather than optional. HS2’s four main civils contractors established a collaboration forum to drive economies of scale on bulk purchases of concrete, steel, and reinforcement bar. New Civil Engineer Across the industry, firms are investing in real-time job costing systems, standardised designs, and repeat supply chains to reduce variability and squeeze out inefficiency.
Alternative materials are gaining traction, particularly cross-laminated timber (CLT) and glulam, which can deliver 20–30% weight reductions compared to traditional structural systems Built Environment while cutting embodied carbon by approximately 40%. ScienceDirect The UK’s Mass Timber Centre of Excellence in Scotland is developing domestic manufacturing capability, with homegrown C16 graded timber running £50 per cubic metre cheaper than imported C24. Notable UK CLT projects include the nine-storey Stadthaus in Hackney Wikipedia and the GenZero school prototype for the Department for Education.
Major housebuilders have adopted a “margins over volume” strategy, prioritising profit protection over output. Cambridge Core Persimmon paused starts on 30 sites and operates its own brick factory to buffer against material prices. Industry consolidation is accelerating — Barratt acquired Redrow, and Persimmon proposed acquiring Cala. Taylor & Francis Online Land purchasing has become highly selective, with developers investing “only where we see the very best opportunities.”
What forecasts tell us about 2025–2030
The consensus view is that construction costs will continue rising at a moderate pace through the rest of the decade, with specific risks from carbon pricing policy and labour shortages.
BCIS forecasts building costs to increase by 15% between 2025 and 2030, with tender prices rising 16–17% over the same period. Infrastructure civil engineering costs are expected to climb 16%, while infrastructure tender prices could rise as much as 24% by Q2 2030 Construction News — reflecting the capital-intensive nature of the government’s infrastructure pipeline. Arcadis projects building tender price inflation of 2–4% annually in the near term, accelerating to 5–6% by 2028–29. Arcadis Turner & Townsend recorded 3.0% UK cost inflation in 2024, with global averages projected at 3.9–4.0% through 2025–26.
For steel specifically, prices are expected to follow their typical 3–4 year cycle, with a trough around mid-to-late 2025 and a peak expected around 2027. The critical wildcard is carbon policy. The UK Carbon Border Adjustment Mechanism, confirmed for January 2027, will apply to steel and cement imports, Carbonchain with market watchers expecting CBAM-related increases of £80–200 per metric tonne for steel from 2026 onwards. Tokio Marine HCC All Steels Trading, a UK supplier, expects an overall price increase of £150–200 per tonne in 2026, “driven more by protectionist policies than fundamental demand Global steel overcapacity — forecast to reach 721 million metric tonnes by 2027 according to the OECD — will provide some counterbalancing downward pressure.
Cement faces a structural cost challenge from decarbonisation. Carbon capture and storage could add $50–100 per tonne to cement production costs, roughly doubling the current cost base. MDPI The UK Emissions Trading Scheme price sits at approximately GBP 49.50 per tonne of CO2 equivalent, S&P Global with shadow carbon prices projected at £75 per tonne in 2030 rising to £160 by 2050. Heidelberg Materials’ Padeswood CCS plant is expected to become operational by 2029, but most analysts believe CCS will not make a significant contribution to cement decarbonisation before 2035.
The Construction Products Association’s Autumn 2025 forecasts project total output growth of just 1.1% in 2025 and 2.8% in 2026 — figures that have been progressively revised downward through the year. Private housing is forecast to grow 2.0% in 2025 and 4.0% in 2026. The Tile Association The BCIS Chief Economist captured the mood: “The ‘get Britain building’ rhetoric hasn’t yet turned into delivery. Demand is broadly flat and inflation is sticky, leaving a stagflation-type squeeze.”
Conclusion
The UK construction materials market has entered a fundamentally different era from the relatively benign conditions of the mid-2010s. The compound effect of COVID-19, the Ukraine war, and the energy crisis delivered a 39% structural uplift in material costs that shows no sign of reversing. While the acute volatility of 2021–22 has subsided, the industry now faces a new set of cost pressures: carbon pricing through the UK CBAM from 2027, GOV.UK the expensive transition to electric arc furnace steelmaking, cement decarbonisation costs, and persistent labour shortages driving wage inflation of 5–7% annually.
The most consequential finding is the growing disconnect between government ambition and industry capacity. Targets of 1.5 million new homes Full Fact and a £725 billion infrastructure pipeline over the coming decade collide with an industry The Chemical Engineer where average margins sit below 2%, insolvencies run at twelve companies per day, and material volumes have fallen to multi-decade lows. BCIS projects that new work output will grow 16–18% by 2030, Roofing Today but this assumes a construction sector capable of absorbing 15–17% cost inflation simultaneously — a challenge that will test even the most resilient contractors. The UK steel industry’s effective nationalisation in 2025, with four of six major producers receiving government financial support, underscores just how fragile the domestic supply base has become. For project sponsors and policymakers alike, the central question is no longer whether costs will rise, but whether the industry can survive the pace of change being asked of it.
