The problem
Energy bills keep rising — and you've been stuck
Until recently you had two options: do nothing, or commit to a big roof installation with scaffolding, installers and weeks of disruption. Most people did nothing.
Sound familiar?
You want to generate your own power but don't want a large, expensive project.
You rent, live in a flat, or don't have a suitable roof.
You dread the complexity: planning rules, installers, certificates.
You’re not alone — this is exactly why the rules changed.
Legal
Plug-in solar now fully legal in England from 27 Aug 2026
The cost of waiting
Every month of delay is a month of paying full price
for electricity you could be generating yourself.
0% VAT on supply-and-install
0% VAT applies to professional supply-and-install only, until 31 March 2027.
New rules are live now
The plug-in rules are in place. The 0% VAT window on professionally supplied-and-installed systems won't last — a plug-in kit on its own is standard-rated at 20% VAT.
Every panel pays you back
The sooner you start, the sooner every panel is working against your bills. Day one matters.
This is a genuine, time-limited window.
The longer you wait, the more it costs.
The key change
Since 27 August 2026, compliant plug-in solar can be legally connected in England — no major building work, no oversized project.
No scaffold needed
DNO notification handled
Start small, scale up
Install-only available
