UK AI Growth Zones 2027: the 5 sites, power, planning and where to host AI

Summary. The UK has five designated AI Growth Zones, and HM Treasury's Data Centre Covenant of 28 October 2026 commits the government to keep delivering all five: Oxfordshire (Culham, named in January 2025), North East England (16 September 2025), North Wales (13 November 2025), South Wales (20 November 2025) and Lanarkshire (29 January 2026). Bidders had to show access to at least 500MW of power or a credible plan to reach it, and the government puts national need at 6GW of AI data centre capacity by 2030. Most zone capacity is still Announced. Lanarkshire is furthest ahead: DataVita has £300m of financing to expand its Airdrie campus and says every megawatt is contracted. South Wales has a first GPU cloud tenant at Vantage's Newport campus, while Stargate UK at Cobalt Park has been paused since April 2026. Two 2027 dates matter: electricity discounts of up to £24/MWh in Scotland and £14/MWh in the North East from April 2027, subject to legislation, and the Edinburgh national supercomputer, due in early 2027. The department that ran the programme, DSIT, closed on 2 November 2026. For 2027 workloads, use live UK cloud regions and GPU clouds already inside the zones; treat zone-scale capacity as a 2028-plus option.

About this article. For CTOs, infrastructure buyers and finance teams deciding where UK AI workloads should run. On 12 November 2026 we checked each claim against GOV.UK pages from HM Treasury, the energy department (DESNZ), the housing department (MHCLG) and the former science department (DSIT), the Scottish Government, UKRI, cloud providers' region lists and operator pages, and used trade press only where no primary source exists. Items marked Announced are plans, not operating capacity. This is not planning, energy or legal advice, and no vendor paid for inclusion. Researched with AI assistance and reviewed by our editorial team.

What changed in 2026, and what is dated for 2027

AI Growth Zones are sites where the government offers faster planning, priority grid access and, from 2027, cheaper electricity in return for very large AI data centre builds. The idea came from the AI Opportunities Action Plan in January 2025. In 2026 the programme moved from naming sites to the harder part: power, planning consents and signed tenants. The application route has no closing date, so more zones can still be named.

Sources for the table: the GOV.UK zone announcements and policy papers, the DESNZ consultation pages, Data Centre Review for the two reported items, and the Scottish Government direction.

The department change matters for anyone tracking announcements. GOV.UK lists DSIT as closed from 2 November 2026, with its work split between the Department for Business, Innovation, Science and Trade (BIST), the culture department (DCMS) and the Cabinet Office. AI Growth Zones and the AI Research Resource now sit with the Minister for AI, a joint BIST and Cabinet Office post. Older pages still carry DSIT branding.

The five AI Growth Zones, site by site

Oxfordshire: Culham

Culham, home of the UK Atomic Energy Authority, was the first zone named, at the launch of the AI Opportunities Action Plan. Its draw, according to Data Centre Review, is the large electrical connection freed up when the Joint European Torus fusion experiment closed.

Delivery is slow. A Freedom of Information analysis by Search Acumen, reported in August 2026, found one relevant planning permission in South Oxfordshire in 2025, against five in 2024 and eight in 2023. The GOV.UK pages we checked give no capacity figure and name no development partner for Culham. Status: designated, partner and capacity not published.

North East England: Cambois and Cobalt Park

The North East was named on 16 September 2025, with the government citing potential for more than 5,000 jobs and Blackstone projecting £10bn of investment at its Northumberland campus. There are two anchors. QTS, owned by Blackstone funds, said in April 2026 that its Cambois campus had planning approval and that piling for the first building would start that spring; it plans up to £10bn and about 720MW across 10 buildings if fully built. Cobalt Park in North Tyneside was to host part of the first Stargate UK deployment from Nscale and OpenAI. On 9 April 2026 OpenAI paused Stargate UK, citing energy costs and regulation, and said it would proceed when conditions allow. Status: one campus under way, one paused.

North Wales: Anglesey and Trawsfynydd

North Wales was named on 13 November 2025. The zone spans Prosperity Parc on Anglesey and Trawsfynydd in Gwynedd, led by a consortium that includes Stena Line, Isle of Anglesey County Council and Bangor University. The government linked it to small modular reactors (SMRs) planned at Wylfa: an initial three, a site that could take up to eight, and power to the grid from the mid-2030s. At announcement, work was under way to find an investment partner, with construction to follow. We found no partner announcement on GOV.UK by 12 November 2026. Status: designated, investor not announced.

South Wales: Newport to Bridgend

Named on 20 November 2025, this zone runs along the M4 corridor from Newport to Bridgend, including the former Ford Bridgend Engine Plant. Vantage Data Centers and Microsoft are the named backers, with £10bn of investment, at least 5,000 jobs and potential for more than 1GW by the early 2030s. It has the clearest early tenant. In August 2026 Nebius agreed to lease capacity at Vantage's CWL1 campus in Newport, operating since 2010, for AI training, inference and enterprise workloads on NVIDIA hardware, and Vantage said it expects more than 1GW across Newport, Bridgend and Bro Tathan. Status: existing campus taking AI tenants; expansion Announced.

Scotland: Lanarkshire

Lanarkshire was named on 29 January 2026, led by DataVita around its Airdrie site with CoreWeave investing £1.5bn and deploying NVIDIA GPUs. The release cited £8.2bn of private investment, 3,400 jobs, a community fund of up to £543m over 15 years, and a DataVita plan for more than 500MW of on-site power within four years.

The power story has since changed. DataVita's FAQ, updated in November 2026, says its data centres are fully grid served and that nearby renewable generation could supply the campus directly in future, through a separate planning application. Read on-site generation as a possibility, not a feature. Financing is real: in August 2026 a £202m National Wealth Fund guarantee unlocked a £300m package to expand DataVita's DV1 and build a second facility, and DataVita said every megawatt was contracted and the first facility would complete in 2026. In September it applied for a further building, DV4, worth about £850m. DataVita advertises under 8ms to London and more than 370 cloud on-ramps (vendor figures). Status: under construction, capacity contracted.

The five zones compared

Across the five, the government counted commitments of at least £28.2bn in private investment and up to 15,000 jobs when Lanarkshire was named, and it made each designation conditional on meeting agreed milestones, so a stalled site can lose its status. Table sources are the site sections above.

Grid, power price and planning: what applies from 2027

Grid connections

The government calls grid connection timing the single biggest blocker for AI Growth Zones. Its November 2025 package promised to reallocate capacity freed when speculative projects leave the queue, reserve future capacity for strategic projects, explore developer self-build of high-voltage lines with Ofgem, and support every zone through the Connections Accelerator Service. On 28 October 2026 DESNZ confirmed it will prioritise strategic demand and strategically align data centre connections, using powers in the Planning and Infrastructure Act 2025. Two follow-ups fall in early 2027: an Ofgem decision on a data centre commitment fee in Q1 2027, and an Ofgem decision on self-build, also expected in Q1 2027 after its consultation closes on 13 November 2026.

The Covenant adds levers for qualifying strategic data centres: transferring pre-2030 connection contracts to them, and a tightly controlled framework for temporary on-site generation until a grid connection arrives, only for exceptionally strategic projects.

Electricity price support

From April 2027, subject to legislative timetables, data centres in AI Growth Zones that help cut grid constraint costs will pay less for power: up to £24/MWh in Scotland, £16/MWh in Cumbria and £14/MWh in the North East, with a review in 2030. The Wales and Oxfordshire zones are not on that list, so their operators should not plan around the discount. The mechanism was left to consultation, and we found no consultation or legislation on GOV.UK by 12 November 2026, so this remains Announced. For a contrasting approach to pricing large loads, see our guide to Dominion's data centre rate class.

Planning

England has moved first. The revised National Planning Policy Framework, published on 17 August 2026, tells plan-makers to take account of AI Growth Zone locations, and policy E2 gives substantial weight to the economic benefits of commercial development, especially where it reflects AI Growth Zone proposals. The November 2025 package also funded a £4.5m national team of AI data centre planning experts and said the government would consider wider reform of call-in powers. The draft Data Centre National Policy Statement is still to come: the Covenant says it will be published for consultation, without a date.

In England, councils are to keep 100% of business rates growth in the zones for 25 years from April 2027, through secondary legislation, worth an estimated £5m to £10m a year per completed site.

Scotland is tightening. Since 16 September 2026, every new data centre above 50MW must submit an Environmental Impact Assessment, and an August 2026 direction requires councils to notify Scottish Ministers of such applications within seven days. Wales also runs its own planning system, so the English measures do not transfer.

The Covenant's tests

The Covenant sets tests that all data centres are encouraged to meet and that strategic data centres must meet to get extra help: a Power Usage Effectiveness (PUE) of 1.3 or better for new facilities, annual reporting of energy and water use, heat reuse where a local user exists, a Local Benefit Plan, UK supplier and apprenticeship commitments, and work with the National Cyber Security Centre on resilience. A Ministerial Control Centre, chaired by the Minister for AI, will consider which strategic sites get faster power and planning. The definition of strategic has not been published. Operators with EU sites will recognise the reporting duty; see our EU data centre reporting guide.

Where UK firms can host AI workloads in 2027

Most UK organisations will not lease a zone campus. They will buy GPU hours, managed AI services or a few racks. Four routes are open.

UK hyperscaler regions. AWS and Google Cloud run London regions, and Microsoft Azure runs UK South in London and UK West in Cardiff. These suit inference close to UK users and managed model APIs, with UK data location today. For help choosing between them, see our cloud computing services.

GPU clouds inside the zones. CoreWeave's capacity with DataVita and Nebius's deployment at Vantage Newport put dedicated NVIDIA capacity in Scotland and Wales. Nebius said in June 2026 it had committed about £1.7bn across four UK sites, according to Data Centre Review.

Public research compute. The AI Research Resource (AIRR), with Isambard-AI in Bristol and Zenith in Cambridge, is set to grow from 21 AI exaFLOPS in 2025 to 420 by 2030. UK-registered small and medium organisations can apply through UKRI's Rapid Access route for up to 20,000 GPU hours, used within three months, for pre-launch AI development. The Edinburgh national supercomputer (up to £750m, Announced for early 2027) adds research capacity, not commercial hosting.

Colocation for your own hardware. DataVita markets research, enterprise and large-scale tiers in Lanarkshire. Most enterprise buyers will enter through a GPU cloud or a smaller colocation contract. If you plan high-density racks, see our 800 VDC power planning guide.

What sovereign means here

The Compute Roadmap defines sovereignty as the ability to direct compute to national priorities and protect sensitive data, with capacity physically in the UK, and says it does not mean isolation or self-sufficiency. The Delivering AI Growth Zones paper accepts that some AI workloads will run offshore with allies. UK GDPR controls restricted transfers of personal data abroad, which need adequacy regulations, safeguards or an exception; it does not by itself require UK-only hosting. A US provider in a UK data centre gives you UK location, but US law can still require it to disclose data wherever the data sits. Decide which of the two your contracts, regulators or customers require.

Latency and cost factors

Light in fibre covers about 200km per millisecond, so each 100km of route adds roughly 1ms of round-trip time. Training jobs tolerate that, and the Roadmap notes training is generally less location-dependent than inference. Chat-style inference for London users is better served from London or Wales. Compare the power price per MWh and whether any zone discount is passed through, the facility's PUE, commitment length, egress and cross-connect fees, and whether quotes include VAT.

Decision table: choose X if

Worked example: 1MW of AI compute in a Scottish zone

Assume a UK fintech runs a 1MW IT load of GPU servers around the clock in a Lanarkshire facility built to the Covenant's PUE of 1.3. We use no base power price, because DataVita does not publish one; only the published discounts.

• Facility draw: 1MW × 1.3 = 1.3MW.

• Annual energy: 1.3MW × 8,760 hours = 11,388MWh.

• If the full £24/MWh Scottish discount were passed through from April 2027: 11,388 × £24 = £273,312 a year.

• The same load in a North East zone at the £14/MWh maximum: 11,388 × £14 = £159,432 a year.

Check the government's headline the same way. A 500MW site drawing full power all year would use 500 × 8,760 = 4,380,000MWh, so £24/MWh would be worth £105.1m. The government's figure is up to £80m a year for a 500MW data centre from its whole package, so it sits below that theoretical maximum; the paper does not state its assumptions. Two cautions apply. The discount goes to the operator, so whether a tenant sees it depends on the contract. And the scheme still needs legislation, so do not bake it into a 2027 budget.

Checklist for UK CTOs before you commit

1. Now to December 2026: classify each AI workload as training, batch inference or interactive inference, and record any UK location or sovereignty requirement in writing.

1. Before signing any zone contract: ask whether capacity is energised, under construction or Announced, and put the energisation date in the contract.

1. Q1 2027: ask suppliers whether they will pass through the April 2027 zone discount, and on what terms if the legislation slips. Watch Ofgem's decisions on the commitment fee and self-build.

1. Early 2027: if you do research work, check AIRR calls and the Edinburgh service launch.

1. Through 2027: watch for the draft Data Centre National Policy Statement and the published definition of strategic data centres.

1. Every contract: confirm PUE, annual energy and water reporting, resilience commitments aligned with NCSC guidance, exit terms and data return.
