Plug-in solar buying checklist · 2026 GUIDE

Before you buy plug-in solar: a 10-point UK checklist

A practical pre-purchase checklist covering the property, permissions, mounting position, consumer unit, socket, product compatibility, DNO and records.

Updated 3 September 2026 · Great Britain unless stated otherwise
Quick answer

Plug-in solar is now a real Great Britain route, but suitability depends on the complete product, your property, electrical installation, mounting location, permissions and network requirements. Use the checks below before buying.

1. Confirm the exact property

Use the full address, not just a postcode, because planning constraints and permissions can vary property by property.

2. Decide exactly where the panels will go

Balcony, garden, wall, garage and ground positions raise different mounting and permission questions.

3. Measure the usable area

Panel dimensions matter. Measure width and height and account for doors, windows, walkways and obstructions.

4. Check who needs to approve the installation

Renters and leaseholders may need landlord, freeholder, housing-provider or managing-agent permission.

5. Check planning constraints

Listed status, conservation areas and Article 4 directions can change the planning route.

6. Look at the consumer unit

Older or unclear electrical protection may justify professional assessment, especially for higher-PV-capacity systems.

7. Inspect the intended socket

Use the exact intended socket. Outdoor socket arrangements need suitable weather protection and the connection must follow the manufacturer instructions.

8. Check the product, not just the panel

The complete kit includes inverter, plug, cabling, connectors and mounting system. Product compatibility is a system-level question.

9. Identify the DNO and follow the network route

Plug-in generation still operates in parallel with the electricity distribution network and must follow applicable G98 requirements.

10. Keep a permanent record

Store the product model, serial numbers, photos, permission evidence, DNO reference and installation date. These records can be useful for property management, warranty and future sale.
