1. 0% VAT Relief
The UK Government provides 0% VAT on residential solar panel installations and standalone home batteries, saving homeowners roughly £1,200 to £2,000 on upfront costs.
2. Smart Export Guarantee (SEG)
Licensed energy suppliers (e.g. Octopus Energy, E.ON Next, OVO) are legally required to pay you for surplus electricity exported to the grid, typically 12p to 15p per kWh.
3. Battery Payback Accelerator
Pairing solar with an energy storage system (e.g. GivEnergy or Tesla Powerwall) allows you to store free daytime solar or cheap overnight off-peak power for peak daytime use.
Built for Radical Consumer Transparency & Rigorous Standards
We reject aggressive lead-capture funnels and unvetted subcontractors. Every installer listed on VerifiedSolar.uk must satisfy our three non-negotiable consumer pillars.
100% MCS Validated
Certification under the Microgeneration Certification Scheme is legally mandatory to qualify for the UK Government's 0% VAT relief and Smart Export Guarantee (SEG) payments.
Zero Cold-Call Guarantee
Your personal contact details are never brokered to aggressive boiler-room call centers. You contact certified engineers directly on their transparent business phone lines.
Direct Warranties
All equipment installations are covered by tier-1 direct manufacturer warranties: minimum 25-year photovoltaic linear performance and 10 to 15-year battery cycling guarantees.
