Institutional property landlords face dual net zero pressure: (1) own-corporate net zero pathway driven by SBTi commitments and investor expectations (TCFD, GRI, SASB disclosure); (2) MEES EPC B by 2030 deadline applied to all let UK commercial property. Solar PV addresses both pressures simultaneously — and tenant-installed solar (under BBP Green Lease Toolkit provisions) delivers the EPC uplift to the building while attributing the Scope 2 reduction appropriately. Prologis, Tritax Big Box REIT, GLP, Blackstone, Segro, Royal London Asset Management, M&G Real Estate, and the major pension-fund-backed REITs all now have standardised tenant solar processes.
Why tenant solar works for institutional landlords
The institutional landlord position on tenant solar has evolved significantly since 2020. Three factors drove the change: (1) MEES EPC B 2030 deadline made EPC uplift across the let estate an urgent priority — and tenant solar is the lowest-cost route; (2) own-corporate net zero pathways (typically SBTi-validated) require Scope 2 reduction across the operational portfolio; (3) tenant demand for solar grew rapidly as customer Scope 3 pressure flowed through. The institutional landlord market settled on the BBP Green Lease Toolkit as the standard framework — addenda to existing leases that allow tenant-installed solar with clear treatment of EPC uplift, dilapidations, end-of-lease handling, and insurance.
For most institutional landlords, the tenant solar process is now standardised: standard BBP-aligned addendum, internal review process (typically 4-8 weeks), property management coordination on insurer review and access. Some institutional landlords proactively offer tenant solar facilitation including pre-vetted installer panel and standard finance options.
EPC uplift attribution
A key technical point for landlord-tenant solar arrangements is EPC uplift attribution. The EPC is a property-level certificate — when solar is installed, the EPC reassessment delivers the uplift to the building (and therefore to the landlord). The energy savings (the kWh consumed on-site) accrue to the tenant who pays the bill. The tenant retains the carbon abatement for their own Scope 2 reporting; the landlord reports the EPC uplift across their portfolio.
This "split incentive" issue (landlord receives the EPC value but tenant pays for the install) is addressed in the BBP Green Lease Toolkit addendum, which specifies treatment options including: tenant retains all energy savings + landlord retains EPC value (most common); landlord rent reduction reflecting EPC value; landlord co-investment in capex sharing both EPC value and energy savings; or PPA structure with third party retaining ownership. Each option has different commercial and tax treatment — we work with both parties on the right structure.
Portfolio-level approach for institutional landlords
For institutional landlords with 50–500+ properties, the right approach is portfolio-level rather than building-by-building. Standardised lease addenda, pre-vetted installer panel, single insurer review process across the portfolio, and consolidated EPC monitoring deliver substantial efficiency gains. Most major institutional landlords (Prologis, Tritax, GLP, Blackstone, Segro) have moved to this portfolio-level approach since 2022.
Our work with institutional landlords typically begins with a portfolio MEES gap analysis: which buildings are below EPC B, what interventions are needed for each, and what's the optimal sequencing. Solar PV is the dominant intervention for warehouse stock; LED lighting and building fabric supplement where needed. The output is a portfolio-level capex plan with sequencing prioritised by lease event timing (re-letting, rent review, lease break) and tenant willingness.
Direct landlord investment vs tenant solar
Some institutional landlords are choosing direct landlord investment in solar PV rather than facilitating tenant solar. The economics differ: tenant solar gives the landlord EPC uplift only; direct landlord investment gives the landlord both EPC uplift and the cash flow from selling kWh to the tenant (typically at a discount to grid retail). For modern long-lease estate where the landlord is confident in long-term tenancy, direct investment can be attractive.
For most existing institutional REIT estate, the dominant model remains tenant-installed solar under BBP addenda — it spreads capex across many tenants rather than concentrating it on the landlord balance sheet, and it preserves tenant Scope 2 reporting which is now important for tenant retention.
Common questions about For landlords
How long does landlord consent typically take?
For institutional landlords (Prologis, Tritax, GLP, Blackstone, Segro): 4-8 weeks under standard BBP-aligned addenda. For owner-occupied or family-owned property: 1-4 weeks. For complex multi-let or mixed-use property: 8-12 weeks. We provide the BBP-aligned addendum template and run the consent process directly with the landlord on tenant's behalf.
Who pays for the install — landlord or tenant?
Most common: tenant pays capex, retains energy savings, claims AIA/FYA tax allowance. Landlord retains EPC value. Alternative: landlord co-investment with capex sharing OR landlord direct investment with kWh sale to tenant via PPA. Each structure has different commercial and tax treatment — we work with both parties on the right model.
How do we handle end-of-lease?
BBP addendum specifies treatment: (a) tenant removes the system at expiry; (b) tenant transfers ownership to landlord at agreed value; or (c) PPA continues with successor tenant. The right option depends on the lease term remaining when solar was installed. We provide a 5-10 year-old system valuation if ownership transfer is the chosen option.
What about insurance allocation?
BBP addendum specifies that the tenant's solar is added to the building insurance with appropriate sub-limit. Landlord buildings insurance covers the property; tenant's contents insurance covers the solar PV asset. Insurer pre-design review is included in our standard project scope and the buildings insurer typically signs off on the design before commissioning.
Can we run a portfolio rollout across our REIT estate?
Yes. We have delivered 6-15 building portfolio rollouts for institutional REIT landlords. The process: portfolio MEES gap analysis, standardised lease addenda template, pre-vetted installer panel, single insurer review process, consolidated EPC monitoring. Typical sequencing prioritises buildings with upcoming lease events (re-letting, review, break) where the tenant cooperation is highest.
