UK Balcony Solar Regulations: Law, Planning, Wiring and Leases
The regulatory picture for plug-in balcony solar in the UK has changed. This page sets out where things stand and what it means for you.
16 July 2026: the framework was delivered
IllustrationThe Current Situation
The government's own statement of the position is unambiguous. In its consultation response, DESNZ wrote that “at present these products cannot be sold or used lawfully in the United Kingdom, as they do not currently comply with the Plugs and Sockets etc. (Safety) Regulations 1994 (PSSR) or the Electricity Safety, Quality and Continuity Regulations 2002 (ESQCR)”. That is the baseline this site works from: not a grey area, and not a matter of interpretation.
SI 2026 No. 848 changes that from 27 August 2026. It amends the PSSR to create an approval route for a standard BS 1363 plug supplied with a “plug-in microgenerator”, and amends ESQCR regulation 22(1)(c) so that such a device must comply with the Interim Product Specification. The practical position is therefore:
- •SI 2026 No. 848 was made on 16 July 2026, laid before Parliament the following day, and came into force on 27 August 2026
- •A device only qualifies if it meets IPS version 2 and is registered and verified compliant on the ENA Type Test Register. Submitting a device for registration is expressly not evidence of compliance
- •As at 8 October 2026, 120 kits were verified on that register
- •The PSSR (plug) limb extends to England, Wales, Scotland and Northern Ireland; the ESQCR amendment that makes use lawful extends to Great Britain only, and the specification records that its application to Northern Ireland is subject to further consideration
- •Notification to your Distribution Network Operator is mandatory, and the specification requires the product itself to say so
The UK is a late adopter here. The government notes that plug-in solar devices “are already widely used throughout several European countries, including Germany, Spain and the Netherlands”, and that the UK framework has been built on the German standard DIN VDE V 0126-95 with UK modifications. Widely quoted figures for German deployment (commonly cited as more than a million registered Balkonkraftwerke) come from German market reporting rather than from any UK government source, so treat them as background rather than as an official statistic.
The Regulatory Landscape: Five Key Areas
G98 DNO Notification
MandatorySmall grid-connected generation falls under Engineering Recommendation G98. IPS version 2 states that notification to your Distribution Network Operator about connection and disconnection is mandatory, and requires the product to carry that statement plus a QR code to the registration guidance. G98 Issue 2 Amendment 1 2026 also restricts installations to one device per household. Since 27 August 2026 it has let a householder notify a plug-in kit themselves, by registering on ENA's site myplugin.solar (the online form of G98's new Form B2). The network operators' own pages haven't caught up yet, so keep your own record.

Position unclearThe DESNZ-commissioned safety study states plainly that "the position of plug-in PV under Permitted Development Regulations (PDR) is currently unclear", and identifies resolving it as necessary future work. IPS version 2 makes obtaining any necessary planning permission and Listed Building Consent the user's own responsibility. Leasehold flats face separate lease requirements regardless of planning.

Referenced by the specificationIPS version 2 requires compliance with BS 7671:2018+A4:2026 and points installers to BS 7671 Section 551.7.2 for the connection of a plug-in solar device. From 27 August 2026, ESQCR regulation 22(1)(c) requires a plug-in microgenerator to comply with the specification. The BSI is developing an enduring UK standard to succeed the interim specification; no publication date has been announced.

Check your leaseMost UK flats are leasehold. Your lease may contain clauses about exterior alterations, and your balcony may be common property rather than demised to you. You may need consent from your freeholder or management company, as well as your landlord.

Improving for rentersThe Renters' Rights Act 2025 (England) has strengthened tenants' position when requesting improvements. While balcony solar isn't specifically named, landlords face a higher bar for refusing 'reasonable' additions, particularly portable systems that cause no structural change.
