UK airport solar — May 2026

Solar for UK airports — Heathrow to regional, glint-and-glare aware delivery.

UK airport solar is a mature deployment market with multi-MWp programmes at every major airport. CAA-approved glint and glare assessment, structured PPA funding, and integration with existing airport power infrastructure define the work.

UK airport solar — major operator programmes

Manchester Airport Group (Manchester, Stansted, East Midlands) — multi-MWp programme since 2022. PPA-funded structures with Atrato and similar funders.
Heathrow Airport — substantial PV across cargo, operational, staff buildings. Heathrow Net Zero 2050 commitment.
Gatwick Airport — multi-MWp PV deployment. Gatwick Sustainability Strategy public.
Birmingham Airport — solar deployment under WMCA Local Growth Fund context (in WMCA territory).
Edinburgh, Glasgow, Aberdeen Airports — Scottish IETF eligibility for SIETF-aligned packages.
Cardiff Airport — Welsh Industrial Decarbonisation route.
Regional airports (Bristol, Liverpool, Newcastle, Doncaster Sheffield, etc.) — progressive deployment 2024-26.

Glint and glare assessment

Any solar array within approximately 3km of an operational runway requires glint and glare assessment under CAA guidance. The assessment models reflective glare from solar modules toward critical aviation surfaces (runways, taxiways, control towers) at all sun angles. Most airport solar arrays use anti-reflective module coatings and tilted-down configurations to minimise reflective risk. Specialist consultancies (Anaglyph, Pager Power, RPS) handle glint and glare modelling.

The 2026 airport solar funding stack

Annual Investment Allowance — 25% effective tax saving for incorporated airport operators
Power Purchase Agreements — dominant at multi-MWp scale
Local Growth Fund — 11 Mayoral Authority areas
Scottish IETF — Scottish airports
Welsh Industrial Decarbonisation — Welsh airports
Airport-specific Department for Transport / DESNZ funding for major decarbonisation projects

EV charging integration

Airport car parks are increasingly significant EV charging deployment sites. Combined PV + EV charging projects on airport staff and long-stay car parks are now standard. Major UK airport EV charging networks include Heathrow EV, Gatwick eMotion, Manchester Airport EV.

Airport solar FAQs

What solar funding is available to UK airports?

UK airports access multiple 2026 routes. The Annual Investment Allowance — 25% effective tax saving for incorporated airport operators. PPAs at scale — multi-MWp PPA frameworks dominate at major airports. Local Growth Fund where the airport is in an eligible Mayoral Authority area (Manchester Airport in GMCA, Birmingham Airport in WMCA, Liverpool Airport in LCRCA). Scottish IETF for Scottish airports (Glasgow, Edinburgh, Aberdeen). Welsh Industrial Decarbonisation for Cardiff Airport. Airport-specific decarbonisation funding through Department for Transport / DESNZ on case-by-case basis for major projects.

What's special about airport solar PV deployment?

Three constraints unique to airports. (1) Glint and glare assessment — solar arrays near runways and taxiways must be assessed for potential reflective interference with pilot vision. CAA approval required for any solar array within ~3km of operational runway. (2) Bird strike risk — airports manage bird populations carefully; solar arrays designed to not attract birds (no standing water, appropriate lighting). (3) Security and operational continuity — airport solar must integrate with airport-specific power systems, often requiring MOD-grade or CAA-grade certification.

Have major UK airports deployed solar PV?

Yes — extensively. Manchester Airport Group runs a multi-MWp programme across Manchester, Stansted and East Midlands. Heathrow has substantial PV across cargo and operational buildings. Gatwick, Birmingham and Edinburgh airports have all deployed multi-MWp PV. Smaller regional airports (Bristol, Liverpool, Newcastle, Aberdeen) are progressing programmes. Major UK airport groups have public net zero commitments and are several years into multi-site PV deployment.

Can airport solar PV go on terminal buildings?

Some terminal buildings yes; most terminal roofs are heavily plant-occupied (HVAC, baggage handling, telecoms) limiting useful PV area. Most airport PV is on cargo buildings, operational buildings (fire stations, maintenance hangars), staff buildings, and ground-mount on adjacent airfield land. Solar canopies over staff and visitor car parks are increasingly common.

Funding by asset class

The allowance depends on the asset, and most pages on this topic get it the wrong way round. Solar PV is special-rate expenditure (HMRC Capital Allowances Manual CA22335), so the 100% year-one route is the Annual Investment Allowance — Full Expensing is a main-rate measure and does not reach it. Battery storage, EV charging and heat pumps are main-rate plant, so Full Expensing genuinely does apply to those.

heat pump capex for commercial buildings
Main-rate plant, so Full Expensing does apply here.
commercial battery storage costs and ROI
Main-rate plant. Stacks with solar for self-consumption.
what commercial solar costs per kWp
Capex bands per kWp before any relief.
rooftop solar on industrial premises
Large roofs, high daytime load — the strongest case.
the Annual Investment Allowance explained for solar
Solar is special-rate, so AIA is the 100% year-one route.

1. A short written funding note naming every scheme your site qualifies for in 2026 — and the ones it does not.
2. Indicative system size and a capex band for your roof.
3. Year-one tax treatment per asset in £ — solar is special-rate expenditure, so the route is the Annual Investment Allowance; battery storage and heat pumps are main-rate plant, where Full Expensing does apply. Most pages get this the wrong way round.
4. Projected SEG export revenue at current rates.
5. Any red-flag eligibility or DNO issues we can see up front.

Covers solar PV, battery storage, EV charging and commercial heat pumps — separately or as one bundled project. If your project is a heat pump or a battery rather than a roof, say so in the message box and the note is written against that asset instead.

What we will not do

· We do not pass your details to multiple installers.
· We do not run a lead auction, and we never ask for your phone number.
· No marketing lists, no unsolicited calls.
· We are an independent funding consultancy — not an installer, and we take no installer commission.

Five questions. They are the eligibility test itself — scheme eligibility in 2026 turns on sector, tenure, site size and spend, so we cannot shortlist anything without them.

Business or organisation name * Site postcode * Determines nation, DNO region and which regional schemes apply. Sector * Approx. annual electricity spend * Roof tenure * Most funding routes and PPAs hinge on this. Work email *
