Summary
- Currie & Brown forecasts UK data centre construction costs could rise by up to 6.8% under higher oil-price scenarios.
- Steel, aluminium, and copper remain exposed to energy, manufacturing, and logistics costs.
- Cost volatility adds to existing UK data centre constraints around power, planning, equipment lead times, and procurement.
Currie & Brown has warned that UK data centre construction costs could rise by up to 6.8% if oil prices remain elevated, adding another pressure point to a market already constrained by power availability, planning, equipment lead times, and specialist labour.
The consultancy’s latest analysis models how oil price volatility could affect construction costs across global markets. Its published research says data centre project costs could rise by up to 8.5% in the US, 6.8% in the UK, and 5.5% in Thailand under higher oil-price scenarios.
Energy prices feed into construction through fuel, transport, manufacturing, and materials. In data centres, that exposure is magnified by the amount of steel, copper, aluminium, switchgear, cable, pipework, generators, cooling equipment, containment, and prefabricated systems required to turn a building shell into critical infrastructure.
MEP intensity carries the risk
Data centres are among the most mechanically and electrically intensive building types. The visible shell may be straightforward, but the cost sits heavily in power distribution, cooling, resilience, controls, and commissioning. A movement in metal, energy, or logistics costs can therefore move the whole project budget.
Currie & Brown’s analysis highlights steel, aluminium, and copper as exposed materials. Copper is already under pressure from grid reinforcement, renewables, electrification, electric vehicles, and data centre power distribution. Aluminium is pulled into similar demand through cabling, containment, support structures, and manufactured equipment. Steel runs through frames, plant support, access systems, and structural components.
The UK data centre market has limited room for extra cost pressure. Demand around London and the South East remains strong, while grid capacity around established clusters is tight. Developers moving into new regions can face uncertain customer depth, local planning scrutiny, connectivity requirements, and long power timelines.
Cost inflation does not only alter capital expenditure. It affects procurement strategy, contract form, contingencies, financing assumptions, and return profiles. A project with a fixed customer commitment may see margins compressed. A speculative development may struggle to hold its economics before financial close.
Buildability is now financial as well as physical
The warning also shows how data centre buildability depends on global supply chains. Transformers, switchgear, UPS systems, generators, chillers, liquid-cooling equipment, busway, and prefabricated power modules are often ordered long before installation. Site activity may be local, but the risk is distributed through factories, ports, metals markets, and energy costs.
AI demand increases that exposure. Higher-density facilities require more sophisticated cooling and more robust electrical distribution. Developers are turning to prefabricated and modular systems to reduce site labour and compress schedules, although those systems still depend on manufactured components and material inputs.
Procurement behaviour is likely to adjust. Earlier ordering, more detailed escalation clauses, tighter supplier due diligence, and greater use of framework agreements can help manage risk. None of those measures creates grid capacity or guarantees planning consent, but they can protect projects from avoidable cost shocks.
Sustainability targets add another layer. Developers may want lower-carbon materials, higher efficiency, and stronger embodied-carbon performance, yet volatile material prices can narrow design choices. Cost pressure can either push more efficient design or make better materials harder to justify.
The UK has given data centres critical national infrastructure status, raising the sector’s strategic profile. The designation does not change the price of copper, shorten equipment lead times, or remove the need for grid reinforcement. Project economics still depend on physical inputs.
Currie & Brown’s forecast places construction cost alongside power, planning, and supply chain as a live constraint on UK capacity. The data centre pipeline is not built from demand alone; it is built from contracts, cables, cranes, cooling plant, and the materials market behind them.
