Can Solar Panels Cut a Retirement Block's Service Charge?

Yes — but through the service charge, not residents’ own electricity bills, and the route to getting there decides whether leaseholders have to be consulted first. Retirement developments are one of the best-suited building types for solar because somebody is home all day, yet they are also one of the most misunderstood, because the building has two kinds of electricity supply and the panels only connect to one of them.

Two supplies, one roof

A typical retirement block has:

• a landlord (communal) supply for the corridors, lifts, residents’ lounge, laundry, scheme manager’s office, door entry and any communal heating or hot water; and
• a separate supply to each flat, billed to the resident by their own supplier.

A rooftop array connects to one of these, and in practice it is the landlord supply. Sharing generation between individually metered flats needs a private-wire arrangement and the agreement of each resident’s electricity supplier, which is rarely practical in a building of dozens of flats.

The consequence is straightforward: the electricity the panels generate replaces electricity the landlord would otherwise buy for the communal areas. Residents pay for the communal supply through their service charge, so that is where the saving lands. It is worth saying exactly that in any letter to residents, so nobody expects their own flat’s bill to fall.

Paying for it: service charge or a PPA

There are two common routes.

Funded through the service charge. The landlord pays for the installation and recovers the cost from leaseholders. In England, if the works are qualifying works and any one leaseholder’s contribution would be more than £250, the landlord must follow the statutory consultation process before the works go ahead. The threshold is in regulation 6 of the Service Charges (Consultation Requirements) (England) Regulations 2003, made under section 20 of the Landlord and Tenant Act 1985. If the consultation is skipped, what can be recovered from each leaseholder is limited unless the First-tier Tribunal grants dispensation.

A power purchase agreement. A provider installs, owns and maintains the panels, and the landlord buys the electricity they generate at an agreed rate. There is no capital contribution from leaseholders, because the panels are not paid for through the service charge — the cost of the electricity is a running cost like any other supply.

Neither route is automatically better. A service-charge-funded system usually produces the larger saving over its life; a PPA removes the upfront cost and the consultation step.

VAT on a retirement block

HMRC’s VAT Notice 708/6 treats houses, blocks of flats or other dwellings and homes providing care for the elderly as residential accommodation for the energy-saving materials relief (section 2.21). Solar panels are a listed energy-saving material, and batteries have been included since 1 February 2024. An installation on a retirement block is therefore zero-rated from 1 May 2023 to 31 March 2027, reverting to 5% from 1 April 2027 — which matters directly to leaseholders, because VAT on a service-charge-funded project is part of what they pay.

Planning: flats, not a care home

One more distinction catches operators with mixed estates. Permitted development for rooftop solar on non-domestic buildings — Class J — applies to buildings other than houses and blocks of flats. A retirement development of self-contained flats is a block of flats, so it uses the domestic class instead, with different limits. Our guide to planning permission for care home solar sets out both.
