Time until certified plug-in solar can legally plug into a standard UK socket
✓ It’s official: the government response was published on 16 July 2026. The PSSR amendment (SI 2026/848) was made on 16 July, laid before Parliament on 17 July, and comes into force on 27 August 2026. From that date, certified kits (up to 800 W, batteryless, meeting the finalised Interim Product Specification v2) can legally connect through a standard socket. Manufacturers now certify kits and retailers stock them. Realistic availability: late summer or early autumn 2026.

What is plug-in solar — and why does it matter?
Plug-in solar panels (also called balcony solar, plug-and-play solar panels, or simply plug and play solar) are compact kits containing one or two solar panels and a microinverter. The microinverter converts the panels' DC output to 230V AC — the same electricity your home uses — and plugs into a standard 13A socket.
From that point, your appliances automatically draw from solar first. Your smart meter slows down. Your bill drops. No account needed. No export tariff paperwork. No roof work. That's why the “plug and play” name has stuck — because that is genuinely all there is to it.
Until April 2026, plug-in solar was banned in the UK due to electrical safety regulations. Energy Secretary Ed Miliband officially announced legalisation on 24 March 2026. On 16 June 2026, DESNZ published the Interim Product Specification and held a public consultation that closed 30 June. Seven major retailers — Lidl, Iceland, B&Q, Currys, Amazon, Screwfix, and Wickes — attended a government roundtable the same day.
Germany already has over 1 million systems installed. Certified UK kits are expected in late summer or early autumn 2026, once the DESNZ PSSR amendment is finalised. Whether you're in a London flat, a Manchester terrace, a Bristol semi, an Edinburgh tenement, or a Cardiff new-build — if you can't do rooftop solar, plug and play solar panels are your answer.

Plug-in solar vs rooftop solar — UK 2026
Two different products for two different households. Plug-in solar suits renters, flat-dwellers, and anyone wanting a £300–£500 starter system. Rooftop solar suits homeowners ready to invest £5,000–£8,000 for full bill displacement.
| Plug-in solar (800W) | Rooftop solar (4 kWp) | |
|---|---|---|
| Typical cost | £300–£500 kit (£260 entry from City Plumbing, ~£499 EcoFlow STREAM) | £5,000–£8,000 fully installed (panels + inverter + scaffolding) |
| Install time | 30 minutes — clamp the panel, plug into 13A socket | 1–3 days — scaffolding, roof work, electrician, sign-off |
| Planning permission | Not required for non-permanent installs (balcony, garden frame) | Permitted development in most cases; listed buildings and conservation areas need consent |
| DNO notification | Self-notify online (G98 framework, up to 800W) | Installer notifies DNO; G98/G99 application via certified contractor |
| MCS certification | Not required — once a kit is listed on the ENA Type Test Register under the DESNZ Interim Product Specification, DIY self-install is compliant | Required for SEG export tariff eligibility |
| Annual output (UK avg) | 650–950 kWh/year (south-facing, unshaded) | 3,500–4,500 kWh/year |
| Annual savings + SEG | £90–£140 bill savings (at 26.11p/kWh, Jul 2026) + small SEG income | £700–£1,200 bill savings + £300–£600 SEG export income |
| Payback period | 3–6 years | 8–12 years |
| Renter-friendly | Yes — portable, take with you when you move | No — fixed to the property |
| Best for | Renters, flats, terraced houses, anyone wanting £300 to dip a toe in | Homeowners aiming for full bill displacement and SEG income |
Plug-in figures: UK 800W south-facing systems, NASA POWER annual averages × 0.80 performance ratio. Rooftop figures: typical 4 kWp install, UK MCS data and Energy Saving Trust guidance. Plug-in savings assume 26.11p/kWh import (Ofgem Jul 2026 cap) + 5p/kWh SEG export. Only one device permitted per household under DESNZ Interim Product Specification. Batteries excluded from interim spec.
How it works
Sun → DC → 230V AC → your wall socket
A UK plug-and-play solar kit has four moving parts: a solar panel, a microinverter, a 13A socket, and your existing home wiring. The microinverter does the work of any rooftop inverter — just smaller and certified for direct plug-in.
Before you buy
3 things to do while you wait for certified kits
01
Check your consumer unit
Older homes (pre-2008) may have Type AC RCDs, which aren't designed for plug-in solar. You need a Type B RCD. A quick check by an electrician costs far less than a kit — worth doing first.
02
Find your south-facing spot
A south, south-west, or south-east facing balcony, garden, or shed roof is ideal. Even a south-facing fence works. Avoid heavily shaded spots — a 20% shade can cut output by 50% or more.

Kit arrived? Your go-live checklist
Whether you're self-installing a certified kit once the DESNZ Interim Product Specification is finalised, or having a CPS-registered electrician connect one now, the same six checks apply on the day your system goes live. Note: only one device is permitted per household, and batteries are not covered under the interim spec.
✅Check the certification mark
Look for a UKCA or CE mark on the microinverter box before you unpack anything. No mark, no install — contact the retailer first.
🧭Mount the panel south-facing
Balcony rail, garden frame, or shed roof — south, south-east, or south-west, unshaded between 10am and 4pm. This is the single biggest factor in your output.
🔗Connect panel to inverter first
Wire the panel to the microinverter via the MC4 connectors before plugging the inverter's mains cable in. Connecting in this order matters for a safe start-up.
🔌Plug in, then pair the app
Plug the microinverter into a standard 13A socket. Open the manufacturer's app — EcoFlow app, or S-Miles for Hoymiles — and pair over Wi-Fi to confirm it's generating.
📋Notify your DNO (G98)
Required within 28 days of connecting — not optional, but usually quick. Many retailers and electricians file this for you; confirm who's doing it before you finish.
🛡️Tell your home insurer
A quick email or call. Some policies require notification of new electrical generation equipment — skipping it could affect a future claim.

Coming Soon: 7 Retailers Confirmed — Lidl, Iceland, B&Q, Currys, Screwfix, Wickes, Asda
✅ Legal from 27 Aug 2026On 16 June 2026, seven major retailers — Lidl, Iceland, B&Q, Currys, Amazon, Screwfix, and Wickes — attended a government roundtable on plug-in solar. The PSSR amendment (SI 2026/848) was made on 16 July 2026 and comes into force on 27 August 2026, so certified kits can legally use a standard socket from that date. No certified kit exists yet: manufacturers now certify products against the Interim Product Specification v2 and retailers stock them. Realistic availability: late summer or early autumn 2026. The ~£400 figure is DESNZ's own estimate for a future certified kit.
Kits from EcoFlow and Hoymiles are available now but plugging directly into a mains socket is not yet fully legal without a CPS-registered electrician. The PSSR amendment (SI 2026/848) was made on 16 July 2026 and takes effect 27 August 2026 — manufacturers now certify and retailers stock. Important: only one device is permitted per household under the DESNZ Interim Product Specification, and battery storage is not covered.
