Do You Need Permission?

In many cases, solar falls under permitted development, but:

  • Listed buildings require approval

  • Flats may need consent

  • Wall-mounted systems may vary

Grid Connection Rules

If connecting to the grid:

  • G98 or G99 application may be required

  • Depends on system size

Electrical Safety
  • Must comply with UK wiring regulations (BS 7671)

  • Proper isolation and protection required

MCS & Certification

DIY systems don’t need MCS, but:

  • You may not qualify for export payments

  • Professional sign-off may be beneficial

Insurance Considerations
  • Inform your insurer

  • Ensure safe installation

Key Takeaway

DIY solar is possible in the UK - but it must be done safely and correctly.
