New technical standards for digital infrastructure published by the UK government this week will mandate minimum broadband performance levels and data centre resilience requirements from early 2027, marking the most significant overhaul of connectivity regulation in a decade.
The Digital Infrastructure Code, developed jointly by the Department for Science, Innovation and Technology and Ofcom, sets legally enforceable benchmarks for internet service providers. Residential connections must achieve a minimum of 100 megabits per second download speed by March 2027, while new business premises in designated commercial zones will require a baseline of one gigabit per second.
The code also introduces tiered resilience standards for data centres, classifying facilities by criticality. Tier 3 and Tier 4 facilities, which host financial services infrastructure or emergency services data, will be required to maintain 99.99 per cent uptime and demonstrate backup power capacity for at least 72 hours. Operators must submit compliance reports annually from 2028.
Industry reaction has been broadly positive, though some providers have raised concerns about the cost of compliance. Mark Holbrooke, chief executive of the UK Digital Infrastructure Association, said the standards would bring much-needed consistency. ‘The UK has made enormous progress on connectivity over the past five years, but the patchwork of voluntary guidelines and local authority requirements has created an uneven playing field,’ he said. ‘A single national framework reduces complexity and gives investors the certainty they need to commit capital.’
The government estimates that full compliance will require approximately 3.2 billion pounds of combined public and private investment over the next three years. Of that, around 800 million pounds will come from the Project Gigabit programme, with the remainder funded by commercial operators.
Rural connectivity remains a particular focus. The code includes provisions for a Universal Service Obligation for broadband, guaranteeing that premises in the final five per cent of hardest-to-reach locations receive a minimum of 30 megabits per second through alternative technologies such as fixed wireless or low-earth-orbit satellite services.
Digital Infrastructure Minister Julia Markham said the standards were designed to future-proof the UK’s digital backbone. ‘Connectivity is no longer a luxury, it is a fundamental utility like water or electricity,’ she said. ‘These standards ensure that households and businesses across the country can rely on their digital infrastructure, whether they are in central London or a remote village in the Highlands.’
