Solar for landlords and rental properties
The problem is structural: the landlord pays for the array and the tenant gets the electricity. Everything about solar on a rental turns on that split — which is why the arrangements that work are the ones where the landlord captures value some other way.
The landlord pays; the tenant uses the electricity. That split is the whole problem, and it is why solar on rentals is less common than the environmental case would suggest.
A unit used on site is worth the import rate it avoids — to whoever is paying the bill. A unit exported earns the SEG rate, which is a fraction of it.
So the arrangements that work are the ones where the landlord is the one benefiting: communal loads, landlord-paid energy, or where export income and EPC improvement carry the case on their own.
Why the arithmetic is awkward
Everywhere else on this site we say the same thing: self-consumption decides whether solar pays, because a used unit is worth roughly six times an exported one.
On a rental with a tenant-held supply account, the landlord captures only the exported fraction — the cheap half — while paying for the whole system. MCS’s own guidance note puts self-consumption for a typical household without storage at 14–23%, which means the landlord’s share is the remaining 77–86%, valued at a few pence a unit.
That is not an argument against it. It is the reason a rental installation needs a different justification from an owner-occupier one.
Where it does work
Landlord-supplied communal loads. HMOs with shared kitchens and lighting, blocks with lifts, pumps and corridor lighting. These run through the day, which makes self-consumption unusually high, and the landlord pays the bill they offset. This is the strongest case available.
All-inclusive tenancies. Where rent includes energy, the landlord is the bill payer and the ordinary owner-occupier arithmetic applies.
Export-led. Where the landlord holds the export arrangement, a large array on a property with low daytime occupancy generates income directly — modest per unit, but it is theirs.
EPC-driven. Where an improved rating affects lettability or regulatory compliance, the value is not in the electricity at all.
Long-term hold with rising energy prices. A landlord expecting to own the property for twenty years is making a different calculation from one expecting to sell in three.
Decide these before installing
Who holds the export arrangement. It follows the electricity account. If the tenant holds the supply, the SEG arrangement usually sits with them, and any assumption that the landlord receives it needs to be made explicit and lawful rather than assumed.
What the tenancy agreement says about the system, access for maintenance, and what happens if the tenant’s use changes.
Who is responsible for faults, and how a tenant reports one.
What happens at handover between tenancies — meter readings, monitoring access, and whether the incoming tenant is told the system exists and how it behaves.
The paperwork, which the landlord should hold: MCS certificate, building regulations compliance, DNO notification, warranties.
From the tenant’s side
A tenant cannot install a rooftop system — it is an alteration to someone else’s building and needs consent.
Plug-in solar is genuinely different, because it is designed to be reversible and to leave no trace. The position, including a free template for requesting consent, is on renting: can your landlord stop you?.
A tenant asking a landlord for solar is asking them to spend money for someone else’s benefit. A tenant asking to install their own plug-in system, at their own cost, reversibly, is asking for something quite different — and it is a far easier conversation.
Knowing which one you are having changes how you open it.
