The publication of the Archaeology and Solar Farms Good Practice Guide (April 2026) is a timely and pragmatic response to the rapid expansion of ground‑mounted solar developments across the UK. For those of us working regularly at the interface between archaeology, planning and renewable energy, the guidance offers a clearer and more consistent framework for managing archaeological risk without undermining delivery.
Several sections of the document stand out as particularly useful in translating principle into practice.
Paragraphs 2.8.8 and 2.9.1 reinforce the importance of understanding where archaeological impacts really arise within solar schemes. By emphasising that impacts are driven by specific elements of ground disturbance – rather than the red line boundary as a whole – the guidance supports a more nuanced approach to evaluation and mitigation. This is especially helpful in dispelling the lingering misconception that solar farms inevitably require blanket intrusive investigation. Instead, the focus is firmly on risk‑led decision‑making, informed by design detail and archaeological sensitivity.
This approach is carried through effectively in paragraph 3.8.3, which highlights the value of aligning archaeological strategies with construction sequencing and programme realities. The recognition that archaeological work must be achievable, proportionate and well‑timed – rather than front‑loaded by default – will resonate with both developers and planning authorities. It provides a robust justification for phased and targeted evaluation strategies where appropriate, supported by clear design information and early engagement.
The more detailed discussion of infrastructure impacts in paragraphs 5.2.7 and 5.2.8 is particularly welcome. Cable routes, access tracks, drainage features and temporary works areas are often where archaeological risk crystallises, yet these elements can be poorly defined early in the design process. By explicitly addressing these components, the guidance gives practitioners and developers a shared language for identifying and managing risk before it becomes a planning or delivery issue. This clarity should help reduce late‑stage surprises and create greater confidence on all sides.
For developers, however, the most immediately practical tool is undoubtedly the checklist in Section 7. When used properly, it has the potential to significantly improve the quality of pre‑application discussions. By prompting applicants to clearly identify all sources of ground disturbance and to think holistically about construction, operation and decommissioning, the checklist encourages a level of transparency that is too often missing at early stages. Its value lies not as a tick‑box exercise, but as a framework for meaningful dialogue between developers, archaeological advisors and planning officers.
Overall, the guidance strikes a sensible balance between safeguarding the archaeological resource and enabling the delivery of much‑needed renewable energy infrastructure. Its emphasis on flexibility, proportionality and collaboration reflects the realities of solar farm development and provides a solid foundation for more consistent decision‑making. If applied in the spirit intended, it should lead to better outcomes – not only for archaeology, but for projects as a whole.
