Scottish private landlords face a tightening regulatory landscape on energy efficiency. The Scottish Government’s proposed minimum EPC standard for private rented properties, alongside rising tenant expectations on energy costs, has put energy efficiency improvements firmly on landlords’ agendas. Solar panels are one of the most effective single measures for improving a rental property’s EPC rating, and in some cases they are also a sound financial investment in their own right.
This guide covers what Scottish landlords need to know about installing solar PV on a rental property: the regulatory drivers, the financial picture, the practical considerations of installing on a property you do not occupy, and how the SEG and EPC implications work for a landlord rather than an owner occupier.
The regulatory backdrop: Scottish private rental EPC standards
The Scottish Government has consulted on, and committed in principle to, a minimum EPC rating of C for private rented properties. Implementation timelines have been revised several times during 2024 and 2025, with the latest indication being a phased introduction during the second half of the 2020s. As of early 2026, the precise dates are not legally fixed, but landlords should plan on the basis that a minimum standard is coming.
For a rental property currently rated D or E on its EPC, achieving a C rating may require a combination of improvements. Common upgrade paths include cavity wall insulation, loft insulation, low energy lighting, and renewable energy generation. Solar PV is one of the most effective single measures for improving an EPC rating because the calculation methodology gives substantial credit for on site renewable generation against the property’s notional energy use.
How solar affects EPC rating in Scotland
EPCs in Scotland are calculated using the Reduced Data Standard Assessment Procedure (RdSAP). The methodology assigns notional annual energy use to a property based on its construction, heating system, lighting, and other factors. On site renewable generation is credited against this notional consumption.
For a typical 3 bedroom Scottish rental with a current EPC rating of D (around 65 SAP points), adding a 4kWp solar PV system typically raises the rating by 6 to 12 SAP points, which is often enough to move the property into the C band (above 69 SAP points). The exact impact depends on the property’s existing efficiency: a poorly insulated property may benefit more from insulation upgrades first, while a property already at the lower end of D may achieve C with solar alone.
Faithful Spark provides an estimated EPC impact assessment as part of the survey for any landlord property where the rating implication is the primary motivation for installation.
The financial picture for landlords: who benefits from the bill savings?
The financial dynamic for solar on a rental property differs significantly from owner occupier installations. The landlord pays for the installation. The tenant typically pays the electricity bill and therefore captures the bill savings from solar generation consumed within the home.
This split creates two questions for the landlord:
- Can the rent be increased to reflect the lower bills? In a competitive rental market with multiple comparable properties, a property with solar and lower running costs is more attractive to tenants. Some Scottish landlords build a modest rent increase into the next renewal to share the benefit. Others retain the rent at market level and use the lower running costs as a marketing advantage to maintain occupancy and reduce void periods.
- Who receives the SEG export payments? The SEG payment is contractually between the supplier and the homeowner registered with the supplier. For a rental property, the landlord is typically the registered owner of the installation but not the electricity account holder. SEG payments can be set up with the landlord as the SEG account holder, even where the tenant is the electricity import account holder. This requires careful coordination with the supplier at the application stage and is one area where Faithful Spark provides specific landlord support.
Tenant electricity savings as a marketing benefit
For a typical 3 bedroom Scottish rental with a 4kWp solar system, the tenant’s annual electricity savings are approximately £200 to £400 per year depending on consumption pattern and time at home. Over a 12 month tenancy, this is a meaningful amount and a clear marketing advantage in a property listing.
Lettings agents in Aberdeenshire increasingly include solar PV provision in property listings as a tenant attraction feature, alongside other energy efficiency measures. For landlords competing for quality long term tenants, the solar provision can shorten void periods and reduce tenant turnover.
VAT treatment for landlord solar installations
The 0% VAT rate that applies to residential solar installations until March 2027 applies to installations on properties used wholly or mainly for residential purposes, regardless of whether the occupier is the owner or a tenant. A standard private rental property qualifies for the 0% rate.
Some specific landlord structures have a different VAT position, particularly where the landlord operates through a VAT registered business or where the property is a furnished holiday let. Faithful Spark provides VAT confirmation in every quote and recommends landlords confirm the position with their accountant for any installation involving a non standard ownership or letting structure.
Capital allowances for landlord solar
For unincorporated landlords (sole traders or partnerships) operating a property letting business, solar PV installations on rental properties qualify as plant and machinery and are eligible for capital allowances. The Annual Investment Allowance covers expenditure up to £1,000,000 per tax year at 100% deduction. The practical effect for a basic rate landlord installing a £7,000 system is a tax deduction of £1,400 in the year of installation. For a higher rate landlord, the deduction is £2,800.
Incorporated landlords (limited companies operating a property business) can claim the same allowances under the Full Expensing regime introduced in April 2023.
The capital allowances treatment for landlord solar is generally more favourable than the equivalent for owner occupiers (who do not get tax relief on solar installation costs because their primary residence is not a business asset). Landlords should treat the capital allowances as part of the financial calculation for any solar installation.
Practical installation considerations for rental properties
Tenant access and disruption
Solar installation on an occupied rental property requires tenant cooperation. Most installations are completed in 1 to 2 days. The work is mostly external (roof access, mounting, panel placement) but a brief internal element is needed to install the inverter, run the AC connection to the consumer unit, and commission the system. Faithful Spark coordinates with the tenant on access and aims to minimise disruption during the work.
Tenant communication
Landlords should notify tenants in writing in advance of the installation. The notification should cover the dates, the access required, what the tenant can expect (monitoring app access, lower bills, possible mild noise during installation), and any agreed adjustment to rent or service charges if applicable.
Insurance implications
Landlord buildings insurance must be notified of the solar installation. Most landlord insurers cover solar panels under buildings insurance once the installation is notified, with no significant premium increase. Faithful Spark provides the documentation insurers typically require: the Electrical Installation Certificate and proof of mounting hardware specification.
Lease and HMO considerations
For HMO properties, the installation does not affect the HMO licence directly, but the landlord should check the licence conditions for any specific provisions about alterations. For shared tenancies under a single AST, all tenants should be notified of the installation. For multiple short tenancies in a building, communication with each occupant is required.
Frequently asked questions
Can I increase the rent after installing solar?
Subject to the lease terms and Scottish private rental regulations on rent increases, you can review the rent at the next legitimate review point. Some landlords build a small rent increase to share the bill savings, while others retain the rent at market rate to maintain occupancy. The right choice depends on the local rental market and the specific tenant relationship.
Who claims the SEG payments on a rental property?
The landlord can register as the SEG account holder while the tenant remains the electricity import account holder. This is a standard arrangement supported by major SEG suppliers but requires correct setup at the application stage. Faithful Spark advises landlord clients on the SEG application process at completion. For more on how SEG payments work, see our guide to the Smart Export Guarantee in Scotland.
Does the tenant need to consent to the installation?
The tenant does not have a veto over installation works that the lease permits the landlord to carry out, but reasonable notice and cooperation on access are required. Most leases in Scotland include landlord rights to carry out improvements with appropriate notice. Faithful Spark works with landlords to coordinate tenant access and minimise disruption.
What happens if the tenant moves out and the new tenant changes electricity supplier?
The SEG arrangement set up with the landlord as account holder continues regardless of changes in the import account. The new tenant deals with their own supplier for electricity import. The landlord’s SEG account remains in place with the original SEG supplier or can be switched to a higher rate supplier at any time.
Can I install solar on multiple rental properties as a portfolio project?
Yes. Faithful Spark works with portfolio landlords across Aberdeenshire and Aberdeen on multi property solar projects. There are typically modest economies of scale on surveys, equipment procurement, and project management when several properties are installed in sequence under a single contract. We provide portfolio level proposals and project planning for landlords with three or more properties.
