UK funding preparation guide
Commercial solar and decarbonisation grant preparation
An energy project needs an evidence-led business case even when a funding search returns no open grant. Separate the building, the applicant and the technology: funding intended for homes or public bodies may not apply to a commercial SME.

Review workflow
What FundingLens helps you do
Keep source facts, caveats and next actions together so your team can decide what deserves attention before application work starts.
Record the premises postcode, occupier, owner and remaining lease term. For rented premises, agree responsibility for improvements, access and maintenance before assuming the applicant can retain the asset for the funder's required period.
Establish an energy baseline using bills, consumption and operating hours. Compare demand reduction with generation options; a solar array, insulation upgrade and heat pump have different design requirements. Obtain competent technical advice on suitability and calculate savings with clear assumptions.
Ask the scheme manager which surveys, consents, grid permissions, procurement steps and installer standards it requires. Keep these checks separate from the funding calculation. A grant award does not establish that a design meets building, electrical or planning requirements.
Use local authority and regional delivery pages to verify the current application round. An old net-zero announcement or UKSPF allocation is useful background, but it is not evidence of an open business application window or a universal intervention rate.
Readiness checks
- Commercial premises and applicant route confirmed.
- Energy baseline and options appraisal prepared.
- Landlord and project permissions checked.
- Technical quotes separate from funding assumptions.
- Cashflow and ongoing maintenance budgeted.
Eligibility caveats
- Domestic grant eligibility should not be transferred to commercial projects.
- Do not order equipment before checking retrospective-spend exclusions.
- Savings estimates and funding availability require independent confirmation.
