Commercial Lease Incentives

Rent-Free Period in Commercial Leases UK

Rent-free period in commercial leases: fit-out period (3-6 months at lease start to allow tenant to make premises operational) vs headline incentive (additional market incentive). During rent-free: service charges, insurance, and business rates typically still payable. HMRC spreading: landlord must spread total rental income evenly over full lease term — rent-free does not create nil-income period (ITTOIA 2005/CTA 2009). Effective annual rent for tax = total rent ÷ lease years. Rent review interaction: headline rent vs effective rent; whether rent review assumes rent-free period depends on review clause assumptions and disregards. Scotland: same HMRC spreading treatment; LBTT NPV calculation excludes rent-free period.

What Is a Rent-Free Period?

Fit-out period: 3-6 months at lease start; allows tenant to install fit-out before trading. Headline incentive: additional rent-free as market inducement — 3-24 months in a tenant's market. During rent-free: service charges, insurance rent, and business rates typically still payable — only rent (and sometimes insurance rent) is waived. SDLT: rent-free period excluded from NPV calculation — reduces NPV and SDLT liability. Must be clearly documented in the lease or a separate rent concession agreement.

HMRC Spreading Treatment

ITTOIA 2005 / CTA 2009: landlord must spread total rental income evenly over full lease term — the rent-free period does not create a nil-income period for tax purposes. Effective annual rent = total rent payable over term ÷ number of years in lease. Example: 5-year lease at £100,000/year with 6-month rent-free → total rent £450,000 over 4.5 paying years; HMRC deems annual rent £90,000 (£450,000 ÷ 5 years). Capital contributions (landlord pays cash contribution instead of rent-free) receive same spreading treatment. GAAP/IFRS 16: lease incentives spread over lease term from tenant's perspective.

Rent Review Interaction

Headline rent vs effective rent: headline = face rent before rent-free; effective = economic return after deducting rent-free benefit. Rent review clause typically assumes hypothetical letting on open market — whether that hypothetical letting includes or excludes a market rent-free depends on the assumptions and disregards. If rent review disregards the rent-free, reviewed rent = full open market headline rent. RICS guidance: express rent review evidence in both headline and effective rent terms; adjust comparables to compare like with like.

Service Charges and Outgoings

Service charges: typically payable during rent-free period — check lease carefully; some leases waive service charges during fit-out period. Insurance rent: payable throughout. Business rates: payable by occupier from date of occupation — empty property relief may apply during fit-out (100% relief for 3 months for most commercial property; 100% for industrial/listed; 50% thereafter). VAT: if opted to tax, VAT applies to rent; during rent-free period no rent is payable so no VAT arises on rent.

Scotland and Best Practice

Scotland: rent-free periods common in Scottish commercial leases; same HMRC spreading treatment; LBTT NPV calculation excludes rent-free period. Negotiate in heads of terms: agree full incentive package (duration, which outgoings are waived, any capital contribution) before instructing solicitors. Total effective rent: model total effective rent (rent + outgoings − rent-free benefit) over full lease term — not just headline rent. Complex arrangements: split periods; staged rent-free; conditional on performance targets — document with specialist commercial property legal advice.

Frequently asked questions

What is a rent-free period in a commercial lease?+

A rent-free period is a contractual period at the start of a commercial lease during which the tenant is not required to pay rent. It serves two purposes: a fit-out period (allowing the tenant to make the property operational) and a market incentive. Other outgoings — service charges, insurance, and business rates — typically continue during the rent-free period.

How does HMRC treat rent-free periods for tax purposes?+

HMRC requires landlords to 'spread' total rental income evenly across the full lease term. Under ITTOIA 2005 (individuals) and CTA 2009 (companies), the effective annual rent for tax = total rent payable over the lease term ÷ number of years in the lease. The rent-free period does not create a nil-income period for tax purposes.

Do service charges continue during a rent-free period?+

Yes, typically. A rent-free period usually waives only rent — service charges, insurance contributions, and business rates continue to be payable. Empty property relief may apply to business rates during a fit-out period when the property is unoccupied (100% for 3 months for most commercial property).

Reverse Premium in Commercial Leases UK
Reverse premium (tenant inducement payment / capital contribution): cash payment from landlord (or outgoing tenant) to induce tenant to take on a commercial lease. Arises in: new lettings of difficult-to-let space; pre-lettings (developer to anchor tenant); lease assignments (outgoing tenant pays incoming tenant); lease surrenders (landlord pays tenant for early surrender). HMRC tax treatment of reverse premium received by tenant: taxable income (NOT capital) — ITTOIA 2005 ss.99-101 / CTA 2009 ss.96-99; spread over the lease term. CIR v Regalian Properties [1985]: income nature confirmed. For landlord paying: capital expenditure (not deductible against rental income); may be enhancement expenditure for CGT. VAT: pure inducement payment — no supply by tenant, no VAT; but where tenant provides services in return (fit-out works) — taxable supply, VAT arises (Marchday Group [1995]).
