• 100% Full Expensing (limited companies) and AIA (all UK businesses) deliver 19-25% effective tax saving on year-one capex
• Smart Export Guarantee tariffs in 2026 reach 15p/kWh (Octopus Outgoing Fixed) for export-led systems
• Regional grant programmes in Bristol & Somerset provide additional capital subsidy where eligible

Editorial disclosure

SEO Dons Ltd operates this website as an editorial advisory and lead-matching service. Our commercial structure:

• We do not sell solar panels, inverters or batteries.
• We do not take commissions from manufacturers — panel, inverter, battery, or monitoring suppliers.
• We are not an FCA-authorised broker or insurance intermediary.

For successful introductions we earn a flat referral fee — agreed in advance and identical across our installer panel — disclosed to the customer in writing before any introduction.

That structure means our incentive is to map the funding correctly, not to push the project that pays us the most. If the right answer for your business is "do nothing this year" or "smaller system than the installer is proposing", that's what we'll tell you.
