City Plumbing 930W Hoymiles Plug-in Solar Kit
Verdict: yes, this exact kit is socket-legal. It is listed Compliant on the ENA G98 Type Test Register under the Plug-in Solar device type (reference CITYP/21096/V1/A4, listed 28 August 2026), which is the listing that lets you plug it into a normal 13A socket yourself under SI 2026/848. No electrician and no Part P is needed. The register entry behind City Plumbing's cheapest two-panel kit. It is a trade merchant listing rather than a brand, so check the panel code on the box matches the register string.

Rough annual savings
| Case | Saving a year |
|---|---|
| London, home most of the day (75% used) | ~£170 |
| Manchester, out all day (30% used) | ~£60 |
Method: the site's standard assumptions from How Much Can You Save: a south-facing 800W system generates 860 kWh a year in London and 756 kWh in Manchester, priced at the Ofgem cap of 26.32p/kWh. We scale to this kit's panel watts (930W), and because the inverter is limited to 800W, panels above about 930W add only a few pounds. These are estimates, not a quote. Unused generation earns nothing, because plug-in solar does not qualify for the Smart Export Guarantee.
Run your own numbers: the payback calculator takes your postcode, orientation and usage, and the savings calculator gives a location-accurate generation estimate.
