This week in UK data centres:
- DataVita submits £849.6m plans for DV4 at Chapelhall — its third facility at the Lanarkshire AI Growth Zone campus — with closed-loop sealed cooling, zero evaporative water use, heat recovery planned for the neighbouring Monklands Replacement Hospital, and an environmental case that directly addresses the scrutiny Scottish data centre development has been attracting
- CPP Investments and Equinix complete the $4 billion atNorth acquisition on 2 September, placing eight operational Nordic data centres and a major development pipeline under joint ownership — the largest data centre M&A transaction to close this year
- The Buckinghamshire Foxglove judicial review case continues to set precedent: the developer accepted binding environmental conditions in April, establishing that EIA mitigation commitments for large data centre applications must be concrete and enforceable, not aspirational — a shift in what planning submissions now need to contain
DataVita submits £849.6m DV4 plans at Chapelhall. The environmental case is the signal.
DataVita submitted a planning application to North Lanarkshire Council on 2 September for DV4, its third data centre at the Chapelhall campus and the next stage of a campus it has operated for over a decade. The project represents £849.6 million of construction investment over two years, supporting 2,650 construction job-years, 120 permanent skilled roles, and a £75 million community investment fund over 15 years. At full buildout the Chapelhall campus is targeting 500MW of on-site power generation.
The substantive signal in the DV4 application is not the financial scale — DataVita already has the NWF-backed financing context from the DV3 announcement last month. It is the environmental specification. The cooling system is closed-loop and sealed with no evaporative cooling, targeting 0.05 litres of water per kilowatt hour or lower — around a thousand times less water than a comparable cycle of domestic washing. Heat recovery is built in from day one, with DataVita in active discussions with the new Monklands Replacement Hospital and the neighbouring BioCity campus on the reuse of surplus heat. The generators will run on renewable HVO fuel under a SEPA permit.
This level of environmental specificity is a direct response to the scrutiny that Scottish data centre development has been attracting. DataVita’s managing director Danny Quinn was explicit: ‘We have seen a lot of data centre speculation in Scotland recently, and the vast majority of it will never be built’. The application is supported by a full suite of technical assessments covering energy and decarbonisation, noise, air quality, transport, flood risk, ecology, and landscape — the kind of submission that the Buckinghamshire precedent (see below) now signals is the floor, not the ceiling, for large applications under environmental scrutiny.
The DV4 submission is also significant as a case study in what a well-structured AIGZ development pipeline looks like in practice: designation in January 2026, NWF-backed financing for DV1 expansion and DV3 in August, planning application for DV4 in September. Three facilities moving in sequence, with 10 years of operational track record on the site underpinning the planning case.

CPP Investments and Equinix complete the $4bn atNorth acquisition. The largest data centre M&A transaction to close this year.
CPP Investments and Equinix completed the acquisition of atNorth on 2 September 2026. The $4 billion transaction places eight operational Nordic data centres and a major development pipeline across all five Nordic countries under joint ownership. CPP Investments holds approximately 51% after committing $1.3 billion; Equinix holds approximately 34% at $895 million; Partners Group reinvested for a 10% stake at $260 million.
atNorth’s operational portfolio — eight data centres across Iceland, Sweden, Norway, Denmark, and Finland — is built on renewable energy and liquid cooling, with development sites under construction or in planning across Sweden, Finland, Norway, and Denmark. The platform targets growing enterprise and hyperscale demand for AI, cloud and HPC workloads, supported by the cooling and power cost advantages that the Nordics offer relative to Western European alternatives — particularly relevant as AI training workloads scale past 100MW and power cost becomes a primary site selection variable.
The transaction is significant for several reasons. It confirms that pension fund capital — patient, long-duration, infrastructure-focused — is the primary capital type now entering the data centre M&A market at scale. The CPP Investments stake is its latest deployment in the sector, building on earlier positions in data centre platforms globally. It confirms Equinix’s willingness to take minority stakes in regional platforms with strong operational credentials, rather than building organically. And it demonstrates that the Nordic market — frequently described as a secondary market for UK-focused operators — is attracting the same tier of capital as established hyperscale corridors.
For operators and investors watching the European M&A market, the atNorth transaction sets a reference point: a platform with eight operational assets, a demonstrated renewable energy and sustainability model, and a credible development pipeline in a power-advantaged region transacts at $4 billion. Partners Group originally acquired atNorth in 2019 — the exit after seven years at this valuation reflects the compounding effect of building genuine operational scale in markets where power availability and sustainability credentials have moved from nice-to-have to primary valuation drivers.

The Buckinghamshire Foxglove case has established planning precedent. Environmental mitigation must be binding, not aspirational.
The Planner’s England round-up this week covered the continuing significance of the Buckinghamshire Foxglove judicial review case, which has now produced a precedent that will shape how large data centre planning applications need to be structured across England. In January 2026, the government conceded at the High Court that it made a ‘serious logical error’ in granting permission for a 90MW hyperscale data centre at Iver, Buckinghamshire, without requiring a full Environmental Impact Assessment. The developer, Greystoke, accepted binding environmental conditions in April — three months after the government concession.
The precedent that case has established is specific and consequential. Data centre developers routinely claim that their facilities will be ‘green’ or run on ‘low carbon energy’ without putting in place any real commitments to ensure this is the case. The Foxglove case has made that much harder to do in future. For any large application where a developer makes environmental mitigation commitments — on power source, water consumption, carbon targets — those commitments now need to be structured as binding planning conditions or Section 106 obligations, not as voluntary aspirational statements in a planning statement.
The implications extend beyond Buckinghamshire. The Gowling WLG analysis of the concession was clear: EIA discipline will be strictly enforced; mitigation cannot be aspirational; and decisions on politically sensitive schemes must be legally watertight. The revised NPPF, the NSIP route for large data centres, and the AI Growth Zone policy framework all support faster consenting — but they do not override the requirement for a legally sound EIA process. The two operate in parallel.
DataVita’s DV4 application — with its full suite of technical assessments, closed-loop cooling specification, hospital heat recovery commitments, and SEPA permit for generator operation — represents what a post-Foxglove standard application now looks like for a developer who takes the planning case seriously. The contrast with the kind of aspirational environmental statements that the Buckinghamshire case has put under scrutiny is not accidental.

The week in one line: DataVita’s £849.6m DV4 submission set the standard for what a post-Foxglove environmental case looks like for a UK data centre application; the $4bn CPP/Equinix atNorth completion confirmed pension fund capital and a major operator platform’s appetite for Nordic renewable-powered infrastructure at scale; and the Buckinghamshire precedent continued to embed itself in how large planning applications need to be structured across England.
