Solar panels and plug-in solar in Scotland

The rules that apply in Scotland: plug-in solar, Scottish planning and building standards, flats and factors, connecting to the grid, export payments and VAT.

Start here

The short version

  1. Plug-in solar is allowed in Scotland for compliant kits since 27 August 2026. Plug it straight into a suitable socket and register it before use.
  2. Planning is Scottish, not English. England’s plug-in planning rule doesn’t apply: check with your council.
  3. A building warrant or listed building consent may be needed separately from planning.
  4. In flats, speak to your property factor or, if you have none, the council, and check your title deeds.
  5. Export payments and 0% VAT work as in the rest of Great Britain.

Layer 2

In more detail

What applies in Scotland.

Plug-in solar

SI 2026/848 extends to Scotland, so compliant plug-in kits of up to 800 VA can be sold and connected to a standard socket. Choose a kit on the Energy Networks Association register, plug it directly into a suitable socket (no extension leads or adaptors), and register it before use. Only one plug-in device per household is allowed for now. See Plug-in solar explained.

Planning and building standards

Planning is devolved. Scotland has its own permitted development rules for domestic solar, and England’s August 2026 change for plug-in solar doesn’t automatically apply. The Energy Saving Trust tells Scottish households to check the requirements in their area before installing plug-in solar. Check through ePlanning Scotland or your local planning authority. A building warrant may be needed for some work, and listed building consent for a listed building; both are separate from planning.

Flats, factors and title conditions

Many Scottish flats are in tenements with shared parts managed by a property factor. The Energy Saving Trust says owners of flats without a freeholder should approach their factor first, and if there is no factor the local authority may be able to help. Title deeds can contain conditions on changes to external walls and balconies. Tenants need their landlord’s written consent. See Renting, leasehold and flats.

Connecting to the grid

For rooftop and wired-in systems, your installer notifies your network operator under G98 within 28 days, or applies first under G99 for larger systems. See G98 and G99 explained.

Export payments and VAT

The Smart Export Guarantee applies in Scotland as in the rest of Great Britain, usually needing an MCS certificate. Installing solar panels or a battery in a home has 0% VAT until 31 March 2027.

Layer 3For the technically mindedThe legal framework in Scotland
  • Plug-in: SI 2026/848 amends the Great Britain-wide Electricity Safety, Quality and Continuity Regulations 2002 and extends to Scotland, with the government’s product specification and G98 Issue 2 Amendment 1 (2026).
  • Planning: Scotland’s own permitted development order and planning legislation; check the current householder permitted development rules with the council or ePlanning Scotland.
  • Building standards: the Building (Scotland) Act 2003 and regulations; your council’s building standards service can say whether a warrant is needed.
  • Property: title conditions and the rules for tenements govern shared and external parts of flats.

Frequently asked questions

Is plug-in solar legal in the UK?

In England, Wales and Scotland, yes, for compliant devices. Since 27 August 2026 a qualifying plug-in solar device can be sold and plugged into a standard socket under SI 2026/848. In Northern Ireland, compliant kits can be sold but are not yet permitted to be plugged in. A kit is only lawful if it meets the government's specification, so an ordinary solar kit with a UK plug fitted is not automatically legal.

Do I have to register plug-in solar or tell my network operator?

Yes. The Energy Saving Trust says you are legally required to register a plug-in solar device before you use it, on the UK Plug-In Solar Registration website, giving your name, postcode and the device's make and model. The government specification also requires your network operator to be notified when you connect and when you disconnect the device. Keep the confirmation you receive, and ask your network operator if you are unsure whether your registration covered that notification.

Full answer with sources

Do I need planning permission for solar panels in Scotland?

Planning is devolved, so Scotland has its own permitted development rules for solar and England's plug-in rule does not automatically apply there. The Energy Saving Trust tells Scottish households to check the requirements that apply in their area before installing plug-in solar. Check through ePlanning Scotland or your local planning authority, and note that a building warrant or listed building consent may be needed separately.

I own a flat in Scotland and there is no freeholder. Who do I ask?

The Energy Saving Trust says to approach your property factor first if you have one. If you do not have a factor, the local authority may be able to help with statutory compliance. Check your title deeds for any conditions on changes to external walls and balconies.

What is the Smart Export Guarantee?

The Smart Export Guarantee (SEG) requires electricity suppliers with at least 150,000 domestic customers to offer export tariffs to small-scale low-carbon generators, including solar PV up to 5 MW, for electricity they export to the grid; smaller suppliers can choose to offer one. You apply to a supplier that offers a SEG tariff. The supplier decides the rate and contract length, but the tariff must always be above zero pence per kilowatt hour.

Is there VAT on solar panels?

For most homes, installation is currently zero-rated. A 0% VAT rate applies to the installation of energy-saving materials, including solar panels, in residential accommodation in Great Britain from 1 April 2022 and in Northern Ireland from 1 May 2023, until 31 March 2027. The reduced 5% rate is scheduled to return after that unless the government extends the relief. The relief is tied to installation, not to materials alone.
