Who Pays for Solar on a Retirement Scheme — and Who Benefits?

This is the question that decides the project, and it is almost never the question a solar proposal answers. On a retirement scheme, the economics are not set by the roof. They are set by which meter the array connects to and who is allowed to pay for it.

Two supplies, one decision

A retirement scheme typically has a communal or landlord supply — lift, stair and corridor lighting, communal lounge, laundry, door entry, fire alarm, warden call, and often central hot water — and demised supplies, one per flat, billed to each resident directly.

Rooftop solar connects to the communal supply in almost every case. So the generation offsets the landlord’s bill. Residents benefit indirectly, through a lower communal cost flowing into the service charge, rather than seeing anything change on their own bill. If nobody explains that up front, residents who contributed through the service charge will reasonably ask why their own bills look identical.

It also sets the ceiling on system size. A scheme where every flat has its own combi boiler and the communal load is lighting plus a lift may only draw a few kilowatts in daylight. Fitting an array sized to the roof rather than to that load produces heavy export at a fraction of the import value, and a payback that never arrives.

The section 20 trap

If any part of the cost is recovered through the service charge and any single leaseholder would contribute more than £250, the Landlord and Tenant Act 1985 section 20 consultation applies. It is statutory: notice of intention, a period for observations and contractor nominations, then a notice of estimates.

Miss it and recovery is capped at £250 per leaseholder regardless of what was spent. On a 30-flat scheme that can mean recovering £7,500 of a £38,000 project, with the balance falling on the freeholder.

Two practical consequences:

• It adds three to four months. Run it alongside the grid application, never after it. Sequencing these one after the other is the most common reason a scheme misses a funding or VAT deadline.
• It can be avoided legitimately. Funding from the reserve or sinking fund where the lease permits, or from the landlord’s own capital with the benefit retained on the landlord’s supply, does not trigger the threshold. Which applies depends on the lease — and the lease governs, not the proposal.

Who has the easiest route

Schemes owned outright by a single freeholder — a charity, an almshouse trust, a housing association holding the whole block — avoid the consultation question entirely and move considerably faster. Mixed-tenure estates with many leaseholders have the most work to do before anyone climbs on the roof.

What to establish first

Read the lease. Identify the communal MPAN. Pull twelve months of half-hourly data on that meter, not on the site total. Then size against what the communal supply actually draws in daylight.
