As Britain enters another summer marked by record solar performance, businesses that have adopted on-site renewable systems are realising clear benefits—reduced operational costs, improved energy independence, and progress toward sustainability goals. Yet for many, this season offers something even more powerful: a strategic opportunity to shape their energy future.
The latest figures from the Department for Energy Security and Net Zero reveal a 45% rise in solar photovoltaic (PV) electricity generation in Q1 2025 compared to the same period last year—remarkable growth, especially given that Q1 is traditionally a lower-output period for solar. The UK’s total installed solar capacity now stands at 18.3 gigawatts, up from 16.2 gigawatts just one year ago.
While this progress is promising, much of it has been driven by domestic and utility-scale investment. Many commercial operations—particularly small and medium-sized enterprises—have yet to harness solar’s full potential. And that presents a clear opportunity.
A Unique Window of Advantage
Mid-summer 2025 is not a deadline; it is a window—one where climate conditions, policy incentives, and market readiness are uniquely aligned. Businesses that act now can position themselves to fully benefit from the 2026 energy season, while avoiding rising costs and future constraints.
Why 2026 Planning Starts Now
The second half of 2025 offers a well-timed platform to prepare for:
- Spring/Summer 2026 solar generation
- Favourable capital allowances that expire in March 2026
- A continued shift in market and regulatory expectations around energy use and carbon reporting
By planning today, businesses can ensure they are not just compliant, but ahead—financially, operationally, and environmentally.
The Strategic Benefits Are Clear
| Benefit | What It Means for Business |
| Energy Cost Control | Reduced reliance on volatile wholesale markets and long-term savings |
| Tax Efficiency | Up to 100% full expensing or 50% first-year allowance available until March 2026 |
| Operational Resilience | Greater control over energy supply and pricing during peak demand periods |
| Sustainability Reporting | Immediate, measurable carbon reductions to meet ESG and client expectations |
| Fleet Electrification Synergy | Solar and EV charging combined can drive down total cost of ownership |
Four Practical Steps to Take Now
1. Assess Feasibility and Energy Use
Evaluate your current electricity profile, identify available rooftop or land space, and consider complementary solutions like storage or EV charging.
2. Align Capital and Tax Strategy
Ensure your finance team understands and plans for available reliefs. Many companies are unaware that solar assets qualify for full or partial tax write-offs through March 2026.
3. Map to Net Zero and ESG Goals
Link solar investment to wider environmental or compliance strategies. Solar and EV integration are visible, auditable steps that resonate with regulators, clients, and internal stakeholders alike.
4. Engage with Installers Early
With strong demand expected in early 2026, now is the time to gather quotes, run feasibility studies, and book installation windows for spring commissioning.
Looking Ahead to 2026: Planning for Progress
The first half of 2026 represents a high-value window for commercial solar implementation. Businesses that start preparing in mid-2025 will be ready to:
- Enter the new financial year with infrastructure underway or complete
- Capture peak seasonal generation and maximise their first-year return
- Lock in current tax advantages before potential policy changes
- Strengthen procurement credentials, customer trust, and investor confidence
Solar isn’t just a technical upgrade. It’s a statement of intent—one that aligns energy efficiency, sustainability, and strategic clarity.
Final Thought
The energy landscape is changing quickly. Solar and EV technologies are now proven, accessible, and increasingly essential. But what sets successful businesses apart is not just access—it’s timing, preparation, and action.
Mid-summer 2025 is a moment of momentum. For UK businesses, it’s a rare opportunity to plan with purpose and move with confidence.
