Solar installation in Croxley Green: from enquiry to handover

Start with the property postcode, ownership position and approximate annual electricity use. Mention planned roof work, an EV, a battery or a heat pump. Explain known access constraints and any conservation or listed-building information you already have.

Croxley Green Solar connects enquiries with partner installers. Completing an enquiry is not an installation contract. The installer you choose confirms its own survey, equipment proposal, price, payment terms and responsibilities.

Partner installers can get your next appointment booked within 24 hours of receiving an enquiry. That describes arranging a booking, not completing a survey or fitting the system within a day. Agree the appointment date, purpose and access arrangements directly.

Ask what information to have ready and who will attend or call. If an initial quotation is based on remote information, clarify which parts remain subject to inspection. A preliminary estimate should not be mistaken for a completed roof and electrical survey.

The assessment should consider roof condition, structure, orientation, shade, available panel space and installation access. Discuss inverter and battery positions, cable routes and the existing electrical supply. Raise future electricity demand before the design is finalised.

Ask for the panel layout and predicted annual generation with assumptions. The proposal should explain system capacity, any export constraint and the expected split between direct use, storage and export. A single savings number is not enough to compare different designs.

Confirm the legal installation company, equipment models, included work, payment schedule and exclusions. Check evidence of claimed certification and the distinction between product and workmanship warranties. Agree who handles any subcontractors and aftercare.

Resolve planning, property-owner consents and the relevant network requirements before the work that depends on them. The installer should explain whether notification or an application is required and how that affects the programme. Keep written approvals with the contract.

Ask when scaffolding arrives, how roof and electrical work will be sequenced and whether any power interruption is expected. Agree working access, delivery arrangements and the procedure for unexpected repairs. Weather and site conditions can change the timetable.

If roofing and electrical work involve different businesses, identify who coordinates them. Before final payment, review the agreed completion requirements and raise any visible defects or missing items through the installer’s process. Avoid treating an app showing generation as the entire handover.

Obtain the equipment and commissioning records, relevant electrical and installation certification, network paperwork, monitoring access and written warranties. Ask for a demonstration of normal operation and the process for reporting a fault. Retain the company’s aftercare details.

Your export supplier confirms the documents and metering needed for its tariff. Apply through its process and keep confirmation of the arrangement. The finished system should come with understandable operating information and a clear route for help.
