Question 1

Is plug-in solar legal in the UK in 2026?

Accepted Answer

Yes. In April 2026, the UK Government officially announced that 'plug-in solar' kits will be available in major shops within months. This follows the 'Right to Plug' legislation and BS 7671 Amendment 4 which simplified the process for systems up to 800W. These kits are now officially recognized as a key way for households to cut energy bills.

Question 2

Do I need to notify my DNO?

Accepted Answer

Yes, but the process is now 'Notify and Fit'. You install the system and then submit a simple online form to your local Distribution Network Operator (DNO) under the G98 standard. No complex prior approval is needed for systems under 800W.

Question 3

Can I use this in a house or just an apartment?

Accepted Answer

Any domestic situation! While popular for balconies, these kits are perfect for houses. You can install them in gardens using A-frames, on shed roofs, or even on a patio. They are far easier and cheaper to install than traditional rooftop solar.

Question 4

Does it work with UK weather?

Accepted Answer

Yes. Modern bifacial solar panels are designed to capture diffuse light, which is common in the UK. While yield is highest in summer, you'll still generate significant power during the spring and autumn to offset your base load.

Question 5

How much can I save on UK energy bills?

Accepted Answer

With UK electricity prices averaging around £0.28/kWh in 2026, an 800W system can save you between £200 and £300 per year depending on your location and panel orientation.
