How We Work

The 6-step office solar install process

From half-hourly feasibility to 25-year O&M. Predictable. Documented. MCS-certified at every stage. Typical end-to-end timeline 6-9 months from acceptance to commissioning.

    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
    • Grant application drafting
    • Building Regs Part A/L/P
    • CDM 2015 designer pack

    Install & commissioning

    Month 6-9

    On site for 2-10 weeks depending on system size. MCS-certified install team, NICEIC electrical certification, daily safety briefings to CDM 2015 standard. Commissioning to IEC 62446 with full performance documentation.

    What you receive

    • Mounting + panels installed
    • String + central inverters commissioned
    • Switchgear modifications complete
    • DNO witnessing visit passed
    • Customer training session

    Documentation & ESG handover

    Month 9

    Customer handover pack: O&M manual, electrical certificates, structural certificates, warranty documents (panels 25-yr, inverters 10-yr, workmanship 10-yr, IWA 10-yr), monitoring access. Plus Scope 2 Disclosure Pack for ESG reporting.

    What you receive

    • O&M handover manual
    • Electrical + structural certs
    • Warranty + IWA documentation
    • Scope 2 Disclosure Pack
    • SEG registration complete

    Ongoing O&M

    Years 1-25

    First 5 years inclusive in capex: quarterly site visits, reactive fault response within 5 working days, EICR every 5 years, annual performance report against PVSyst model. Optional extension years 6-25 at £12-18/kWp/year.

    What you receive

    • Quarterly inspection
    • Annual cleaning (where needed)
    • Reactive fault response
    • Annual performance review
