Getting to Completion: Negotiating a Commercial Lease in 2026

If you are negotiating a commercial lease in London, England or Wales in 2026, careful preparation at Heads of Terms stage can significantly improve the final outcome. The current market presents opportunities for occupiers to secure more resilient commercial lease terms, enhanced flexibility and better protection against unexpected costs. This guide highlights key commercial lease negotiation tips for UK tenants and explains the lease completion process for commercial property transactions.

1) Repairs and condition: capping liability with a schedule of condition 

Full repairing leases on older stock can be expensive. Use a schedule of condition to cap liability to the property's existing state. If the landlord is undertaking EPC or plant upgrades, include coordination duties and consider time-limited rent abatements where disruption is material. 

2) Service charge cap strategies and transparency 

Service charge cap commercial lease negotiation remains one of the most important areas of negotiation for occupiers, particularly where service charge expenditure has historically fluctuated. Use the RICS 2nd edition standard, effective from 31 December 2025, as leverage for caps on volatile lines, clear apportionment bases, disclosure of commissions and rebates and timely budgets/accounts. Where service charge years commenced before 31 December 2025, consider the RICS/ICAEW transition point; for service charge years ending 31 December 2026 and beyond, RICS expects the new provisions to be fully in place and adopted. 

3) EPC and ESG clauses: agreeing who pays for what 

Agree access and co-operation provisions for cost-effective EPC measures, arrangements for energy data sharing where available, and clear drafting on whether EPC-related works are landlord capital expenditure, recoverable service charge expenditure or tenant fit-out responsibility. Following the Government's June 2026 interim response, larger private rented non-domestic buildings over 1,000 square metres are proposed to require EPC B from 2031, where cost-effective, while smaller buildings are intended to remain subject to the current EPC E standard. The relevant uplift still requires secondary legislation, so leases should be drafted flexibly. 

4) Alterations, signage and reinstatement 

Secure licences for alterations with clear scope, planning and building regulations responsibilities, approvals, turnaround times and proportionate reinstatement. Avoid blanket reinstatement where works are beneficial or compliance-driven.

5) Alienation and group reorganisations 

Permit assignment to group companies, reasonable underletting where appropriate and avoid automatic AGAs where the incoming covenant is satisfactory on objective tests. 

6) Security of tenure (Landlord and Tenant Act 1954) 

If the lease is outside the Act, ensure the warning notice and tenant declaration formalities are handled correctly before grant. If it is inside the Act, plan the renewal strategy early. The Law Commission published its second consultation paper on 16 June 2026, but the current 1954 Act regime remains in force pending any enacted reforms. 

7) Pre-completion checks and post-completion housekeeping 

Understanding the lease completion process for commercial property transactions helps reduce delays and ensures key post-completion obligations are not overlooked. These typically include title and searches, replies to CPSEs, agreed compliance information, completion mechanics, SDLT filing, HM Land Registry registration and the Register of Overseas Entities (ROE) checks where overseas entities are involved. 

8) Pricing levers now that the 2026–2029 rating list is live 

Now that the new rateable values have taken effect in England and Wales from 1 April 2026, consider stepped rent, extended rent-free or landlord contributions to fit-out where overall occupancy cost is higher than expected. Because a change in rateable value does not always translate directly into the same change in the rates bill, tenants should model multipliers and reliefs as part of overall occupancy cost. If service charge budgets are uncertain, use caps or a temporary retention until the first reconciliation. 

9) Rent review drafting: upwards-only reviews under review 

If your lease includes a rent review, be aware that the English Devolution and Community Empowerment Act 2026 includes provisions affecting upwards-only rent reviews in business tenancies. The enabling legislation has received Royal Assent, but the relevant provisions are not yet in force and secondary legislation is expected to provide the details. Do not assume that historic upwards-only drafting will remain market standard for new leases or renewals; take advice on alternatives such as fixed increases, stepped rents, genuine upwards/downwards reviews or other mechanisms suited to the asset and sector. 

Whilst every transaction differs, resilient commercial lease terms generally include proportionate repair obligations, sensible service charge protections, workable break rights, reasonable alienation provisions and practical EPC compliance obligations. Identifying these provisions early often improves negotiating leverage and reduces transaction risk.

Negotiating a commercial lease: frequently asked questions 

What clauses should I negotiate first in a London commercial lease? 

Prioritise repairs and condition, supported by a schedule of condition if appropriate, service charge caps and transparency, workable break conditions, clear alterations and alienation rights, and the insurance provisions. 

How are service charges negotiated, and how do I avoid a surprise bill? 

Service charge negotiations commonly focus on annual service charge caps, exclusions for landlord improvements, transparency requirements, apportionment methodologies and timing of budgets and reconciliations. Cap volatile lines where possible, require an apportionment matrix and require timely budgets and accounts with supporting information. Check whether the RICS 2nd edition and any transition point need to be reflected in the service charge arrangements. The appropriate approach will depend on the drafting proposed by the landlord and the characteristics of the building. 

Do I need to contract out of the 1954 Act? 

It depends on your strategy. Contracting out can give flexibility at lease end; staying inside provides renewal rights. Take advice early and complete the formalities correctly if contracting out. The Law Commission's review is ongoing, but the current regime continues to apply unless and until reform is enacted. 

What lease terms are most negotiable in the current London market? 

Depending on the property type and market conditions, tenants may be able to negotiate rent-free periods, service charge caps, break rights, repair liabilities, alteration rights, alienation provisions and rent review mechanisms. Incentives may also include landlord fit-out contributions, stepped rents and capital contributions for alterations, and may be particularly relevant where landlords are seeking to attract occupiers to secondary office or retail stock. The extent of any flexibility will depend on the landlord's position and current market demand for the premises. 

Should tenants push for shorter leases with break clauses in 2026? 

This will depend on the tenant's business objectives. In uncertain trading conditions many occupiers favour either shorter lease commitments or longer leases combined with tenant break options, allowing flexibility if business requirements change. 

What is a rent review clause and how does it work? 

A rent review clause provides a mechanism to adjust rent during the term of the lease. Reviews may be based on open market rental value, index-linked increases, fixed increases or other agreed methods. The precise mechanism will depend on the lease wording. 

What happens between exchange and completion of a commercial lease? 

Once legal documentation is finalised, the parties typically complete agreed pre-completion requirements, arrange execution of documents, deal with funds transfers and prepare for occupation. Following completion, additional obligations may include SDLT filings, registration requirements and compliance with any agreed conditions.
