Data Centre Planning Consultants
Urban Vista Planning advises operators, developers and landowners on planning permission for data centres, AI compute facilities and the grid infrastructure that serves them. From site appraisal to consent, we build the planning case around the issues that decide data centre applications: power, Green Belt, noise and national need.

Data Centres and the Planning System
Data centres have moved to the centre of national planning policy. They were designated Critical National Infrastructure in 2024, the National Planning Policy Framework now asks councils to identify suitable locations for data centres and recognise their specific locational requirements, and AI Growth Zones are being established to concentrate investment where power is available.
Policy support does not guarantee consent. Applications are still decided on power availability, Green Belt, noise, landscape, water and energy use, and local planning authorities vary widely in their experience of these schemes. A well-evidenced application that anticipates these issues is the difference between a timely approval and a lengthy appeal. Our guide to data centres in the Green Belt explains the grey belt test and recent decisions.
Our head office in Taplow is a few miles from Slough, one of Europe's largest data centre clusters, and we advise on schemes across the Thames Valley, the London fringe, the Midlands, the North and South Wales. See our local pages for Berkshire, Buckinghamshire, Hertfordshire, London, Manchester and Newport.
The Issues That Decide Data Centre Applications
Power & Grid
Grid capacity is usually the deciding factor. Substations, cable routes and on-site generation often need their own consents, and planning should be programmed around the connection date.
Green Belt
Many sites near London and the major cities are Green Belt. Grey belt policy and national support for digital infrastructure have changed the balance, but the case must be carefully evidenced.
Noise & Air Quality
Cooling plant runs continuously and backup generators are tested regularly. Robust assessment and mitigation are essential where homes are nearby.
Water & Energy
Cooling water demand, energy efficiency and waste heat reuse are increasingly scrutinised by councils, water companies and consultees.
What We Help With
- Site search and appraisal: power, fibre, flood risk, Green Belt and planning history
- Consenting strategy: local planning permission, section 35 NSIP direction or permitted development
- Green Belt, grey belt and very special circumstances cases
- Grid connection, substation and cable route consenting
- Noise, air quality and backup generator strategy
- Energy, heat reuse and sustainability statements
- EIA screening, scoping and Environmental Statement coordination
- Transport assessments and construction traffic management
- Biodiversity Net Gain, landscape and design strategy
- Community consultation, local authority engagement and planning appeals
Common Scenarios
- →You have secured, or are pursuing, a grid connection and need planning permission to match
- →You want to redevelop a warehouse or brownfield site as a data centre
- →Your preferred site is in the Green Belt and you need a robust grey belt or very special circumstances case
- →You are planning a hyperscale or AI campus and need to decide between local and NSIP consenting
- →You need a new substation, cable route or on-site energy centre to serve a data centre
- →Your data centre application has been refused and you want to appeal
Why Urban Vista Planning?
Data centre consenting draws on planning, highways, energy and environmental expertise at once. We act as lead planning consultant, coordinating acoustic, air quality, landscape, ecology, drainage and transport specialists so the application tells one coherent story.
Infrastructure Specialists
Experience across energy, grid, transport and telecoms consenting, not just general development.
Planning & Highways
MRTPI and MCIHT accredited, so transport and access are handled in-house.
Fixed Fees
Transparent, staged fees aligned to your programme and grid connection milestones.
Thames Valley Based
Head office in Taplow, near the Slough cluster, with offices in Leeds and Hereford.
Frequently Asked Questions
Does a data centre need planning permission?
A new data centre building requires planning permission. Data centres are usually treated as Use Class B8 (storage or distribution), although some authorities consider larger facilities to be sui generis. Converting an existing B8 warehouse may therefore not need change-of-use permission, but external works such as cooling plant, backup generators, substations and security fencing usually do. We confirm the position at the outset so the right consent is sought.
Can a data centre be built in the Green Belt?
Yes, in the right circumstances. National policy now gives specific support to data centres and digital infrastructure, and the 'grey belt' introduced in the December 2024 NPPF has changed how some Green Belt sites are assessed. Where a site is not grey belt, the case rests on very special circumstances, such as national need, the locational requirements of data centres and the availability of power. Several large Green Belt data centre schemes near the M25 have been approved at ministerial level on this basis.
Can a data centre be consented as a Nationally Significant Infrastructure Project?
Large data centres can ask the Secretary of State for a direction under section 35 of the Planning Act 2008 to be treated as nationally significant, which means consent is sought through a Development Consent Order rather than a local planning application. Government has also signalled a move to bring data centres more formally within the NSIP regime. Whether this route is better than a local application depends on scale, timing and the associated grid works. We advise on the right route for each project.
What assessments does a data centre planning application need?
Typical requirements include a noise impact assessment (cooling plant and generators), an air quality assessment (backup generator testing and emergencies), an energy and sustainability statement, a transport assessment, flood risk and drainage, landscape and visual impact, ecology and Biodiversity Net Gain, and heritage where relevant. Larger campuses usually need EIA screening and may require a full Environmental Statement.
Do backup generators need separate permits?
Often, yes. Diesel or gas backup generators may need an environmental permit from the Environment Agency (or Natural Resources Wales) under the medium combustion plant and specified generator rules. This is separate from planning permission, but the planning application still needs to address air quality and noise from generator testing. We coordinate both so the evidence is consistent.
How long does planning take for a data centre?
Major applications have a statutory determination period of 13 weeks, or 16 weeks where EIA applies, but data centre schemes often take longer because of negotiation on power, noise and Green Belt matters. From site appraisal and pre-application advice through to a decision, 9–18 months is typical. Grid connection timescales are frequently the critical path, so we align the planning programme with the power strategy from day one.
