Plug In Solar: Kits, Components and the UK Offer

Plug In Solar is a name householders search for, but it is not one company. It is the category of kit that became legal to buy and use across Great Britain from 27 August 2026, when the panels could be plugged into homes across the country¹. The kits are sold by several suppliers and retailers, and the rules that govern them are set centrally rather than by any one brand.

The shape of the offer is fixed by those rules. Each plug-in solar kit produces up to 800W of power, enough to provide up to 20% of an average home's electricity use, and it comes with no installation cost². A household is limited to a single 800W plug-in kit for safety reasons³. More than 50 compliant kits were listed on the type test register as of 16 September 2026⁴.

What follows is the kit itself, how the socket connection works, who is selling what, what the incentives position actually is, and where the limits of a plug-in system sit for a household's energy independence.

What a plug-in solar kit contains

A kit is a small, complete generating set rather than a collection of parts. The Centre for Sustainable Energy describes kits as likely to include one or two panels, an inverter, mounting equipment, cable and a standard three-pin plug³. Which? gives the same list in more detail: one or two solar panels, a microinverter that converts direct current to usable alternating current, a lead fitted with a standard three-pin plug, mounting brackets and an app for monitoring⁴.

The official product specification sets a minimum. A plug-in solar device comprises at least one PV module, a grid-following inverter, a connection lead fitted with a plug complying with BS 1363 and a mounting system for the panel⁶. The same specification classifies devices into three types: one-component, two-component and multi-component⁷. That classification matters because it determines what has been tested as a unit.

Panel output in the kits now on sale is commonly 400W per panel, with one or two panels per system⁸. Which? records kits with two 435W bifacial all-black panels and an 800VA microinverter, and others with 2x460W panels and an adjustable bracket for walls, floors and balconies⁴. The type test register lists some kits as comprising UKSOL solar panels and Hoymiles microinverters, and others as including JA Solar panels⁴.

How it works: a mains socket, no electrician

The defining feature is the connection method. The official specification describes a plug-in solar device as intended for connection to an existing low-voltage electrical installation using a standard UK mains plug and socket, without requiring installation of a separate electrical circuit for export⁶. The government consultation set out the same aim: to allow consumers to connect plug-in solar systems without batteries directly to a standard mains socket, provided products meet defined safety requirements⁹.

That removes the two things that make rooftop solar a project: scaffolding and a qualified installer. Plug-in solar panels are designed to be self-install, provided the manufacturer's instructions are followed⁵, and anyone can install them without the need for a professional installer or electrician⁴. The panels can be plugged directly into home sockets without additional wiring, reducing electricity taken from the grid¹⁰.

There are conditions on the socket itself. The device is designed to be connected to a UK mains socket solely by the manufacturer-supplied plug, and it shall only be connected to socket circuits, not to circuits supplying lighting or other fixed equipment¹¹. Safety guidance is firmer still: always connect the system directly to a suitable outdoor wall socket, and never plug a solar panel into an extension lead⁹.

The connection is also portable in a way rooftop solar is not. One network operator's guidance is to plug into a standard UK socket, power everyday appliances, and take the kit when moving¹³. That is the practical difference between a kit and a fixed array.

The UK offer: retailers, suppliers and kits now available

Plug-in solar panels have been available to buy online and on the high street since the end of August 2026⁴, and major retailers have worked with the UK government on the rollout, with panels now available in stores and online¹⁴. The government named Currys, B&Q, Screwfix and Amazon as retailers that have worked on the rollout and would soon have them available in stores and online². Amazon, Argos, Currys and Wickes have all committed to stocking plug-in solar panels².

The named suppliers behind the kits are a shorter list than the retailers. Which? records UKSOL plug-in solar kits available online at Argos, with hybrid mount kits coming soon⁴. It also records an InstaGen kit with two 435W bifacial panels, an 800VA microinverter and a universal mounting frame, and PowerXpress kits with 2x460W panels and an adjustable bracket⁴. Octopus Energy offered two plug-in solar bundles, both including JA Solar panels⁴.

Prices are quoted as published by the sellers and the VAT position is not stated in those figures. The general market range is £500 to £1,000 for a solar panel kit³. A UKSOL kit contains the solar module or modules, an ENA-compliant microinverter, a 4m AC cable and 2m DC cables, and a purpose-designed mounting solution¹².

Kits with or without government incentives: what the makers claim

The incentives position is narrower than the marketing around plug-in solar sometimes suggests. There is no general grant for a plug-in kit. What exists is a funding pilot specifically designed to put plug-in kits into low-income households, delivered through local authorities⁸. That is a targeted programme, not an entitlement.

The planning position is separate from money. Under the 2026 Order, solar PV expressly includes plug-in solar, which means plug-in solar is subject to the limitations and conditions in Classes A and B¹⁵. Cornwall Council's guidance on solar panels and planning permission sets out the permitted development framework that applies to domestic solar¹⁶. The underlying legislation defines solar PV as solar photovoltaics including plug-in solar¹⁷.

Where a scheme does require certification, the standard is explicit. The Barcud Solar Panel Installation Scheme Specification requires that solar PV systems are only installed and certified by MCS certified contractors working to the latest published MIS3002 standards¹⁸. That is a condition of a particular scheme, and it points to the difference between a self-installed plug-in kit and a contractor-installed system.

The wider context is that UK rooftop installations have been happening without government subsidies for rooftop installations²⁰, and clean power records have continued to be broken as capacity has grown²¹. Plug-in kits sit inside that market rather than on top of a support scheme.

The Plug In Solar range: DIY kits, new-build kits and battery storage

The range now on sale divides into a few recognisable shapes. The simplest is a single-panel kit on a ground mount, such as the UKSOL Compact 460W Plug-In Solar Pro Kit at from £599.00⁴. The next step up is a two-panel kit with an adjustable bracket for walls, floors and balconies, which is what PowerXpress offers with 2x460W panels⁴. The largest kits in the current listings pair two 465W panels, as in the PatioSun Max Plus at £779⁴.

Mounting is where the range varies most, because the panel has to go somewhere. UKSOL lists a Hybrid Mount Plug-In Solar range with wall or ground mounting and four power options from 515W to 1260W, listed as coming on 1 October 2026²². That range sits above the 800W connection ceiling, so the higher options are not straightforwardly a single plug-in device under the current rules.

Battery storage is the least settled part of the offer. Plug-in solar batteries are already being developed for the UK market⁸, but the government consultation that opened the market was framed around plug-in solar systems without batteries designed to be connected directly to a standard UK mains socket and to operate alongside the electricity network²³. The interim product specification covers electrical design, British plug requirements, mounting systems and fire protection²³.

Choosing a kit: what to check before buying

The first check is electrical, and it comes before purchase. Electrical Safety First advises that all homes are checked for suitability and safety by a competent electrician before buying plug-in solar panels²⁴. The Renewable Energy Association's guidance is to have the home's electrical installation checked before installing a plug-in solar system, particularly in an older property⁹. The Energy Saving Trust publishes a plug-in solar checklist that may be helpful to review before purchasing⁹.

The second check is whether the specific model is on the list of devices that meet UK standards, which can be confirmed on the ENA Connect Direct LCT device register⁹. That register is the practical test of compliance, and it is the reason the count of compliant kits matters: more than 50 were listed as of 16 September 2026⁴.

The third check is physical. Panels are often around 1m by 2m and weigh more than 20kg, so many consumers may seek to purchase them with mounting in mind²⁴. The kit's own mounting frame, tilt angle and cable length determine whether a balcony, wall or garden position actually works.

On certification, MCS operates standards including MCS 005 for solar photovoltaic modules and MCS 017 for building integrated photovoltaic products²⁵. Certified installers use MCS certified products, including solar heating panels and mounting kits, and an MCS certificate is a record that the installation was done by a certified installer using certified products²⁶. A self-installed plug-in kit does not travel that route, which is why the type test register rather than an MCS certificate is the relevant check.

What owning a plug-in kit means for energy independence

A plug-in kit changes one thing materially: it lets a household generate some of its own electricity without a contractor, a roof survey or a fixed installation. The kit plugs into a standard UK socket, powers everyday appliances, and can be taken along when the household moves¹³. That portability is a genuine form of independence, particularly for renters and for anyone who cannot commit to a roof.

The dependence that remains is substantial and worth stating plainly. The kit operates alongside the electricity network rather than instead of it²³, so the home stays connected to a supplier and to the grid. Output is capped at around 800W, which is enough for everyday appliances but leaves higher-use appliances drawing from the grid⁵. Government figures put the contribution at up to 20% of an average home's electricity use², which means the large majority of demand is still met by imported power.

There is also a safety-driven dependence. A standard plug-in kit is not a backup power supply and shuts down automatically if the grid supply fails¹², so it offers nothing during an outage. The kit's inverter, its compliance status and its monitoring app tie the household to a manufacturer, and the app ties monitoring to a phone. For a household weighing the options, plug-in solar kits sit at the low-commitment end of the scale, while balcony solar covers the mounting question and plug-in solar vs professionally installed solar sets the two routes side by side. The wider picture of what self-generation can and cannot deliver is at solar panels and household energy independence.
