The UK has set an ambitious target: 45GW of solar capacity by 2030.
But one of the country’s greatest clean energy opportunities is already built, operational, and hiding in plain sight — the roofs of UK warehouses.
According to the UK Warehousing Association (UKWA), the UK’s logistics and warehousing sector has more than 420 million sq ft of rooftop space capable of supporting solar PV. Unlocking that potential could deliver up to 15GW of solar generation capacity, producing:
- 13.8 TWh of clean electricity annually
- 4.3 million tonnes of CO₂ savings
- Enough electricity to power the equivalent of every home in Manchester, Birmingham, and Leeds combined
Yet despite the scale of the opportunity, adoption remains limited. Today, only a small proportion of UK warehouse roofs are generating renewable energy.
That is why collaboration between industry, government, and delivery partners is becoming increasingly important.
Ortus Energy and SSE Energy Solutions Supporting the UKWA Solar Toolkit
Ortus Energy and SSE Energy Solutions are proud partners of the UKWA Solar Toolkit initiative — an industry-defining resource designed to accelerate rooftop solar deployment across the logistics and industrial property sector.
Launched to provide practical commercial, technical, and legal guidance, the Toolkit helps warehouse operators, landlords, occupiers, and asset managers understand how rooftop solar can be delivered at scale.
The initiative aligns directly with the Government’s national solar ambitions and the growing need for businesses to strengthen energy resilience while reducing operational emissions.
As part of this work, Ortus Energy’s Head of Legal & Compliance, Adam Oliver, joined Jon Kirby of SSE Energy Solutions alongside senior representatives from government and industry at the UKWA Ministerial Roundtable on industrial rooftop solar.
The session, attended by Michael Shanks MP, Minister of State for Energy Security and Net Zero, focused on practical steps needed to unlock rooftop solar deployment across the UK warehousing and logistics sector.
Drawing on Ortus’ experience delivering funded solar PPAs on complex commercial sites, Adam highlighted the role of legal collaboration and long-term partnership structures in accelerating adoption.
“Fully funded PPAs can unlock dormant roof space and deliver meaningful ESG impact without capex. A simple legal presumption in favour of solar could be transformative for the sector.”

Turning Roof Space into Long-Term Energy Assets
At Ortus Energy, we are already seeing how large-scale rooftop solar can transform commercial and industrial estates.
Through fully funded rooftop solar Power Purchase Agreements (PPAs), delivered in strategic partnership with SSE Energy Solutions, businesses can generate clean electricity on-site with:
- Zero upfront capital investment
- Long-term energy price certainty
- Reduced operational carbon emissions
- Fully managed delivery and maintenance
For high-energy users in logistics, cold storage, food distribution, and manufacturing, rooftop solar is becoming a strategic infrastructure decision rather than simply a sustainability initiative.
Iceland Foods: 28 Food Centres, One Solar Strategy
A strong example of this approach in action is Iceland Foods.
Working in partnership with SSE Energy Solutions, Ortus Energy has supported Iceland Foods in deploying rooftop solar across multiple food distribution centres as part of a broader operational decarbonisation strategy.
Together, these sites are generating more than 6 million kWh of clean electricity annually while helping reduce operational emissions and improve long-term energy resilience.
The Iceland Foods Deeside distribution centre — featured within the UKWA Solar Toolkit — demonstrates how funded solar PPAs can unlock large-scale renewable generation without requiring upfront capital expenditure.
This is precisely the type of practical, commercially viable action required to support the UK’s net zero ambitions while helping businesses futureproof energy costs across large property portfolios.
Rooftop Solar Is Now a Strategic Priority
Momentum is building across the logistics and industrial property sector.
The launch of the UKWA Solar Toolkit marks a significant shift in how rooftop solar is being viewed — no longer as an optional sustainability measure, but as a strategic energy and asset management opportunity.
For landlords, occupiers, asset managers, and sustainability leaders, the opportunity is substantial:
- Underused roof space can become revenue-generating clean energy infrastructure
- PPAs remove the barrier of upfront capital investment
- Portfolio-wide emissions reductions become commercially achievable
- Long-term electricity cost certainty supports operational planning and resilience
As Mia Sylvester, Head of Partnerships at Ortus Energy, highlighted during the Toolkit launch, collaboration and education remain critical to unlocking the sector’s vast untapped solar potential.
With the right commercial structures and delivery partners in place, rooftop solar can become operationally simple, financially attractive, and scalable across industrial real estate portfolios.
The Time to Act Is Now
The UK’s warehouse rooftops represent one of the country’s largest untapped clean energy assets.
For businesses managing warehousing, logistics, manufacturing, and industrial estates, the roof above them may already hold the answer to lower emissions, reduced operating costs, and stronger energy resilience.
Ortus Energy remains committed to working alongside SSE Energy Solutions, UKWA, policymakers, landlords, and occupiers to help unlock that opportunity at scale.
Because delivering net zero requires more than ambition. It requires practical infrastructure, commercial clarity, and industry collaboration.
