Commercial solar handover checklist: what UK businesses should receive
This commercial solar handover checklist explains the records, operating information and responsibilities UK businesses should confirm before accepting their installation
A commercial solar installation needs a clear handover so your facilities and finance teams can operate it confidently. Before the project closes, agree what information you will receive, who will own it and who will act if the system stops reporting.
This practical checklist is for businesses in Stockport, Greater Manchester and across the UK. It should be tailored to your contract, system and site; it is not a substitute for project-specific technical advice.
1. Commercial solar handover checklist: system records
Ask for an organised handover pack with the installed equipment schedule, relevant drawings, operating instructions, test and commissioning records, and warranty information. Keep a shared copy where your facilities team can find it when the original project manager is unavailable.
The Zero Carbon Accelerator commissioning and handover guide, developed for healthcare estates, provides a useful reference for documentation and commissioning. Its checklist needs adapting to each project rather than treating every item as a universal requirement.

2. Confirm the grid paperwork and settings
Ask the installer to explain which network connection process applies and record the agreed connection conditions, any export limit and outstanding actions. Where G99 applies, Electricity North West’s distributed generation guide explains commissioning and witness testing. Keep correspondence and completion records together rather than assuming an application means every stage is finished. Confirm current project requirements directly with your network operator.

3. Test monitoring access before sign-off
Confirm that the business has its own monitoring access, that the system is reporting and that named staff know how to read the dashboard. Record who receives alerts, who investigates missing data and how you will contact support. A lost internet connection and a generation fault need different responses.
4. Separate forecasts from measured results
Keep the original generation and financial assumptions alongside the handover documents. Agree a reporting period and the data you will compare: generation, site consumption, imports and exports where available. A forecast is a planning estimate; it is not a measured saving or a guarantee.
For a board report, identify which figures come from meters and which are estimates. Note tariff assumptions and any missing data so the next report can be compared on a fair basis.
5. Agree ownership and ongoing care
Write down warranty contacts, maintenance responsibilities, support arrangements and the process for reporting faults. If the property is leased, make sure the relevant landlord and tenant responsibilities are clear. Ask who maintains monitoring connectivity and who keeps records when equipment is replaced.
Handover is also the time to agree safe access for future maintenance. Do not climb onto a roof or open electrical equipment to complete this checklist. HSE guidance highlights the risks of working on fragile roofs; arrange inspection and electrical work through competent people using suitable controls.

Make handover part of the project plan
For a new installation, agree the handover deliverables before work starts and keep an action list for anything outstanding at completion. For an existing system, begin by collecting the records you already have and identifying the gaps.
