Whilst searching for other information I came across this invitation to tender for a safety study of plug in batteries.  This appears to parallel what the government did for plug in solar.  Its an 18 month contract starting 25th Nov 2026 earliest, in two phases

The first phase, which concludes with recommended technical and regulatory adaptations to permit legal, safe use of plug-in batteries, is scheduled to run for 8 months.  

There is a second phase the outcome of which is "Recommend technical and regulatory adaptations to enhance the safety of indoor installations of domestic batteries."  This appears to relate primarily to electrician installed systems and runs until March 2028.

Assuming that plug in can be legalised after the first phase and the contract starts 25th November, so that takes us to June 2027 for this phase to complete.  When the same exercise was done for plug in solar it then took 2 further months to develop the technical standard/product specification.  This was against a background of a public ministerial commitment to an accelerated timescale, its quite plausible therefore that it will take longer for the 'battery' spec to be developed, consulted on, published and legislated for.

Thus I think this tells us that plug in batteries will not become legal until Q3, p2027, possibly even Q4 2027.

If anyone has a more optimistic interpretation I would be delighted to hear!
