By 2050, National Grid says Britain\u2019s data demand alone will use nearly as much power as the entire UK industrial sector consumes today.<\/p>\n
But the grid capacity crunch is already starting to bite in parts of the south.<\/p>\n
T&T says long delays for grid connections are pushing up tender prices and derailing development plans.<\/p>\n
In capacity hot spots like West London, Swindon, Milton Keynes, Oxfordshire and Cambridge, councils report property schemes being stalled by lack of local capacity.<\/p>\n

<\/a><\/div>\n<\/div>\nThe report warns that the delays are already being priced into bids as suppliers hedge against uncertainty.<\/p>\n
T&T predicts building tender price inflation is set to creep up from 3.0% in 2025 to 3.5% next year. Infrastructure inflation will outstrip this at 4.5% this year, rising to 5.0% by 2028, driven in part by the connection squeeze.<\/p>\n
The UK\u2019s fragmented energy framework set-up means developers must apply for connections through one of 14 regional Distribution Network Operators. Waits of several years are now common.<\/p>\n

<\/a><\/div>\n<\/div>\nSince 2024, applicants have had to show they have landowner backing via a Letter of Authority to reduce speculative bids. From this Spring, a major rule change kicked in switching connection priority from \u2018first come, first served\u2019 to \u2018first ready, first connected\u2019.<\/p>\n
The aim is to reward shovel-ready projects, but it\u2019s also ramped up the pressure on developers to get organised fast.<\/p>\n
T&T is urging early action including opting for temporary low-capacity connections to prioritising brownfield sites with legacy power access or installing on-site generation.<\/p>\n

Martin Sudweeks, UK managing director of cost management at T&T, said: \u201cThis surge in demand will only add to the intense competition between construction projects, presenting a risk that costs could rise as suppliers factor uncertainty into their tender prices.<\/p>\n
“Successfully managing power access is now mission-critical to keeping costs stable and delivery on track.\u201d<\/p>\n
