Some landlords are blocking tenants from using plug-in solar kits – but communal systems could avoid disputes
Plug-in solar kits recently introduced to the UK market give residents a fresh method to lower electricity costs, though access remains restricted for many occupants. Numerous housing associations have prohibited tenants from deploying the £700 portable units, citing safety hazards, regulatory hurdles, and liability ambiguities.
In response to these limitations, solar hardware supplier Allume Energy has advocated for shared solar configurations as a viable substitute. Jack Taylor, the company's European general manager, stated that integrated rooftop systems pairing shared panels with energy storage can trim individual annual utility costs by as much as £490. This projection originates from performance metrics collected between July 2025 and June 2026 across 24 units in a Cardiff apartment building. However, potential savings depend on building layout, roof exposure, power usage patterns, and specific utility pricing, alongside landlord willingness to finance initial installation.
A separate project executed alongside energy supplier E.ON involved equipping six apartments in a Stevenage complex operated by Peabody Housing with centralized solar generation. Taylor noted that this setup can also dispatch excess power to the national grid during peak load intervals, potentially providing residents an additional £160 in annual revenue beyond their direct bill reductions.
Independent Solar Consultants advisor Justin Dring noted that social housing providers often favor centralized installations over resident-installed systems. He explained that allowing tenants to independently procure and mount equipment introduces operational complications and elevates the likelihood of residents installing substandard hardware or structurally incompatible components.
Capital expenses for communal systems depend heavily on structural specifications and participant counts, with Allume reporting a per-flat cost of approximately £2,800 for the 24-unit Cardiff property. Deployment requires housing providers to secure tenant consensus, a process that often extends implementation timelines. Taylor clarified that full building participation is not mandatory, allowing uninterested residents to opt out without disrupting service to participating units.
Government officials estimate portable plug-in arrays can decrease annual energy costs by up to £110, framing them as an accessible approach for immediate consumer savings. However, Energy Minister Martin McCluskey confirmed last month that state subsidies to lower the £700 purchase cost are not currently planned.
Housing providers L&Q and Sovereign Network Group, which jointly manage roughly 200,000 properties throughout England, confirmed an absolute ban on tenant-installed plug-in units. Sovereign urged government authorities to provide clearer regulatory guidelines to reassure social landlords. Similarly, the G15 group of major housing associations acknowledged the technology's potential while noting that member organizations are still evaluating structural insurance implications and safety risks.
State financial assistance remains available to housing associations through the Warm Homes: Social Housing Fund to upgrade property energy efficiency. Funding caps allow housing providers to obtain up to £7,500 per residential unit, an amount Allume states can fully fund communal solar installations under suitable property conditions. Public officials also announced an additional £100 million expansion to the fund earlier this year, explicitly allocated for solar and battery storage ventures.
