The UK Government recently published its most ambitious solar strategy, aiming to nearly triple solar capacity from 18GW to 45-47GW by 2030. For commercial and industrial property owners, the Solar Roadmap provides a huge opportunity in commercial solar deployment.
We’ve been closely analysing what this roadmap means for our clients, and if this roadmap is implemented fully, it presents the opportunity for commercial decarbonisation at scale.
The Commercial Solar Revolution is Here
The roadmap’s most significant shift is its explicit focus on unleashing a “rooftop revolution.” The Government has identified commercial buildings as offering some of the most considerable untapped potential, with the UK’s 20% largest warehouses alone providing 75 million square metres of roof space – enough to support around 15GW of solar capacity.
This isn’t wishful thinking. The Government has already removed the 1MW planning permission cap, holding back larger commercial rooftop installations. Projects that previously faced months of planning delays can now benefit from permitted development rights, dramatically reducing timelines and costs.
The UKWA has highlighted the potential of UK warehousing roof space for years, so seeing the Government include them in the discussion and ask them to contribute to the roadmap is refreshing.
What the Numbers Mean
Let’s talk specifics. The roadmap estimates that commercial solar could reduce annual electricity costs by 40-80%, potentially saving the warehouse sector £3 billion annually.
The Government’s analysis shows that achieving the 2030 target could support up to 35,000 jobs, doubling current employment in the sector. More importantly for our clients, it signals a mature, stable market with long-term government backing.
It will be interesting to see how attracting and training talent works practically as the green skills gap is growing.
Regulatory Tailwinds Accelerating Deployment
The roadmap addresses many of the barriers in commercial solar projects. Long overdue grid connection reforms will streamline the process for smaller-scale generation, with new “Fast Track” approvals for systems under 14.72kW and clearer timelines for larger installations.
The upcoming Future Buildings Standard review could be significant for commercial landlords with portfolios. The Government is consulting on options that would mandate solar on new non-domestic buildings, transforming solar from an optional upgrade to a standard requirement.
Perhaps most tellingly, Great British Energy’s first major project focuses on commercial and public sector deployments, enabling around 200 schools and 200 hospitals to install rooftop solar. This signals where the Government sees the quickest wins.
The Supply Chain is Maturing
One aspect often overlooked in commercial decarbonisation discussions is supply chain reliability. The roadmap tackles this head-on, with new measures to ensure ethical sourcing and combat modern slavery in solar supply chains. For asset managers with strict ESG requirements, this government-led focus on supply chain integrity removes a significant due diligence burden.
The roadmap also supports UK manufacturing of balance-of-system components; the inverters, racking, and cabling represent significant value in commercial installations. This should improve both supply security and project economics over the coming years.
Strategic Implications for Our Clients
For our clients who own and manage commercial portfolios, the roadmap creates several strategic imperatives:
Timing is Critical: The Government’s 2030 target means the next five years will see unprecedented deployment rates. Early movers will secure the best grid connections and installation teams before capacity constraints emerge.
Scale Matters: The roadmap’s focus on large-scale deployment favours portfolio approaches over one-off installations. Asset managers with multiple suitable buildings should be thinking strategically about phased rollouts.
Integration Opportunities: The emphasis on battery storage integration and smart grid technologies means commercial solar is becoming part of broader energy management strategies, not just a standalone cost-saving measure.
Financing Gets Easier
The roadmap signals several financing improvements that will benefit commercial deployments. Contract for Difference (CfD) reforms may extend terms beyond 15 years, improving project economics for larger installations. More significantly, the Government is exploring how to better support Power Purchase Agreements (PPAs) with sub-investment grade counterparties, potentially opening new financing routes for smaller commercial operators.
What This Means for Implementation
Combining improved planning processes, grid connection reforms, and government backing creates a perfect storm for deployment.
However, success in this new environment requires more than just recognising the opportunity. Projects need strategic planning considering grid capacity, optimal sizing for current and future energy needs, and integration with broader sustainability strategies.
The roadmap’s emphasis on skills development also highlights the importance of working with experienced delivery partners who understand large-scale deployment’s technical and commercial complexities.
Looking Forward
The Solar Roadmap shows that the Government is serious about how the UK approaches solar and, therefore, commercial decarbonisation. The message for asset managers and owner operators is clear: commercial solar is rapidly becoming a strategic necessity.
The next 18 months will be critical as the detailed implementation of planning reforms, grid improvements, and financing mechanisms takes shape. Those who move decisively now will be best positioned to capitalise on what promises to be the most extensive commercial solar deployment programme in UK history.
The roadmap has set the destination. The question for commercial property owners is no longer whether to deploy solar, but how quickly they can get there.
