As the UK pushes towards its 2050 net-zero target, solar panels, heat pumps, battery storage and EV charging points are showing up on more commercial properties every year. For landlords, these installations can lift a building's EPC rating and its letting appeal.
For tenants, they can mean lower energy bills and stronger ESG credentials. The problem is that most standard commercial lease precedents were drafted long before renewables were a mainstream concern, so they rarely handle the practical questions that crop up.
Who owns the kit? Who pays to maintain it? What happens when the lease ends? This guide walks through the clauses that matter most, the friction points that tend to come up in negotiation, and the practical steps either side can take to protect their position.
What this document is
A renewable energy clause is any provision in a commercial lease that deals with the installation, operation, ownership or removal of low-carbon energy equipment on the demised premises or the wider building. In practice, this covers rooftop solar PV, air and ground source heat pumps, battery storage, EV charging infrastructure, and in some cases connections to district heat networks or private wire arrangements with neighbouring sites.
Because renewables often involve physical alterations to the roof or structure, connections to the national grid, and long payback periods that may outlast the lease term, they cut across several areas a standard lease already deals with: alterations, repair, service charge, yielding up and reinstatement. Rather than relying on those general provisions, most modern leases now include bespoke wording to spell out exactly what the tenant can install, what consents are needed, how costs and benefits are split, and what happens at the end of the term. Getting this right at the heads of terms stage saves a lot of argument later.
How to use this document
Map out what the tenant actually wants to install. Before drafting starts, get specific about the technology, the likely footprint, roof loading, cabling routes and any planning or building regs implications. Vague clauses referring to 'renewable energy equipment' cause disputes later, so pin down the scope early and attach technical specifications or plans to the lease as a schedule where possible.
Deal with consent and the alterations regime. Decide whether the installation sits inside the general alterations clause or needs its own bespoke consent mechanism. In most cases the landlord's consent should not be unreasonably withheld, and it is worth setting out the information the tenant must provide, the timescale for a response, and whether a licence for alterations will be required before works begin.
Allocate costs, ownership and benefits clearly. Agree who funds the capital cost, who owns the equipment during the term, who benefits from any feed-in tariff, Smart Export Guarantee payments or private wire income, and how maintenance and insurance are handled. Ambiguity here causes real friction, especially where the landlord wants to recover costs through the service charge.
Plan for the end of the term. Set out whether the tenant must remove the installation, can leave it in place, or must transfer ownership to the landlord, and on what basis. Consider reinstatement of the roof or fabric, decommissioning standards, and how any remaining value in the equipment is accounted for if the landlord takes it over.
Address grid connection and operational issues. Cover who applies for and pays for the DNO connection, who holds any export agreements, and how the parties cooperate on metering, access for maintenance, and compliance with MEES and EPC obligations. A clear access clause covering inspection and repair of rooftop kit is particularly important in multi-let buildings.
Q Can a tenant install solar panels without the landlord's consent?
Almost never. Solar panels are structural alterations affecting the roof, so the landlord's written consent is normally required under the alterations clause, usually by way of a licence for alterations. Even where the lease says consent cannot be unreasonably withheld, the landlord can legitimately ask about roof loading, waterproofing, insurance, and reinstatement obligations before agreeing.
Q Who owns solar panels installed by a tenant during the lease?
Ownership depends on what the lease says. If the panels are treated as tenant's fixtures and the lease is clear about this, they typically remain the tenant's property and can be removed at the end of the term. If ownership is silent, there is a risk the equipment becomes part of the landlord's property on installation, which is why an express clause matters.
Q How do renewable installations affect the service charge?
If the landlord installs renewables that serve common parts or the whole building, the capital and running costs may be recoverable through the service charge, subject to the lease wording and any RICS code obligations. Tenants should check whether the service charge clause permits recovery of improvements as well as repairs, and whether caps or exclusions apply.
Q What happens to renewable equipment at lease end?
This should be set out expressly. Options include requiring the tenant to remove the equipment and reinstate the premises, allowing the tenant to leave it in place, or transferring ownership to the landlord at an agreed value or for nil consideration. Without a clear clause, reinstatement disputes and dilapidations claims become much more likely.
Q Do MEES regulations affect renewable energy clauses?
Yes. The Minimum Energy Efficiency Standards restrict letting commercial property below a minimum EPC rating, and the threshold has been tightening. Renewable installations can improve an EPC rating, so landlords increasingly want cooperation clauses requiring tenants to provide information, allow access for improvement works, and not do anything that worsens the rating.
Q Who pays for the grid connection?
This is a negotiation point. The tenant installing the equipment usually pays the Distribution Network Operator connection costs and holds any export agreement, but where the installation benefits the wider building or the landlord is contributing to the capital cost, the allocation can be shared. Clear drafting avoids arguments when connection charges come in higher than expected.
Q Can a landlord force a tenant to contribute to renewable upgrades?
Only if the lease permits it. Some modern leases include green clauses that oblige tenants to cooperate with sustainability improvements and, in some cases, contribute to costs through the service charge. Older leases rarely contain such provisions, so landlords typically have to negotiate them in at rent review, lease renewal or as part of a separate agreement.
Renewable energy provisions sit across alterations, service charge and yielding up, which is why they cause so much friction at negotiation and lease end.
