    Free desk feasibility

    Day 1-7

    Send half-hourly meter data + roof plan. We pull historic PVSyst irradiance for your site, model 3 sizing scenarios (conservative/optimised/ambitious), confirm planning route, and return a fully-modelled proposal within 7 working days.

    What you receive

    • PVSyst yield model
    • Three sizing scenarios
    • Capex range per scenario
    • Planning route assessment
    • Grant mapping (AIA, PSDS, WCS, SEG)

    On-site survey

    Week 2-4

    Our structural and electrical engineers visit. Roof condition assessed to BS EN 1991 (dead + wind loads), main switchroom checked, cable routes designed, shading verified on-site, DNO incoming capacity confirmed.

    What you receive

    • Structural calculation
    • Electrical single-line diagram
    • Cable route plan
    • Final inverter spec
    • Fixed-price proposal

    Permits & DNO application

    Month 2-6

    We handle planning (Permitted Development notification, Prior Approval, or full planning where required), G99 grid connection application with the local DNO, and any grant paperwork (PSDS, IETF, etc).

    What you receive

    • Planning submission
    • G99 application + DNO consultation
