What this site does not do
We do not predict what regulators will do next, and we do not report a rumour as news. Every entry here is dated from a document that exists and that we have read. Where something is expected but has not happened, it is marked upcoming and left there.
How it happened, in ten documents
From a code modification proposal in April to everything commencing on a single day in August. The compression at the end is the interesting part.
ENA raises the G98 changedone
The Energy Networks Association raises Distribution Code modification DCRP/MP/26/02, seeking to amend Engineering Recommendation G98 to allow plug-in solar to connect.
BS 7671 Amendment 4 publisheddone
The IET and BSI publish Amendment 4 (2026) to BS 7671:2018. It may be implemented immediately; the previous version is withdrawn six months later.
Interim Product Specification, Version 1.0done
DESNZ publishes the first Plug-in Solar Device Interim Product Specification. It is later withdrawn and superseded, and copies still circulate stamped Withdrawn.
Consultation opensdone
DESNZ consults on amendments to the Plugs and Sockets Regulations and on the Interim Product Specification. It runs for two weeks.
Consultation closesdone
Respondents raise batteries, leaseholder and landlord consent, older wiring, and how the standards would apply in Northern Ireland.
Government response and Version 2.0done
DESNZ publishes its response and the Interim Product Specification Version 2.0. The exclusion of batteries is retained despite objections that it reduces payback.
Reporting on what the documents actually say, including the parts the market has not caught up with.
Three things commenced on the same day
The instrument came into force, the G98 amendment took effect, and the permitted development right for solar equipment changed. The third of those has had almost no coverage, and it is the one that decides whether a given home can proceed.
The updated permitted development right prohibits plug-in solar fixed to wooden walls, balconies and timber cladding. Every retailer in the country calls the product balcony solar.
Respondents argued that excluding batteries reduced consumer payback. The exclusion was kept. Plug-in battery systems and solar integrated with batteries remain outside the approved class.
G98 applies to Great Britain only, the ESQCR amendment does not extend to Northern Ireland, and the department has said applying the specification there needs further consideration.
Not a weekly newsletter. There is one open question worth watching, and one date in 2027. When either moves, you get an email. Otherwise you hear nothing.
