Free Months, Firm Commitments: Pricing a Commercial Lease Incentive in 2026

Few phrases in UK commercial property carry as much reassurance as "twelve months rent free". On the board outside a vacant unit, or in the brochure for a secondary office floor, the incentive often appears to be worth more than the rent itself. For a business weighing a move in 2026, the temptation is to treat the discount as the deal. It is better understood as one clause among many, and rarely the most valuable one.

Headline rent is a starting position, not a price

The figure quoted on the particulars is the sum the landlord wishes to be seen to achieve. It matters for three reasons beyond the tenant's own cash flow: it anchors the next letting, it feeds the rent review, and it supports the investment valuation. A rent-free period, by contrast, costs the landlord less than a permanent reduction in the same headline figure, and it can be withdrawn at the next letting without any public evidence of a softening market.

That asymmetry explains a good deal of what tenants encounter. In many regional office, retail and light industrial markets, incentives have stayed generous while quoting rents have held firm. The tenant's task is not to secure the largest discount on offer, but to establish what the occupation genuinely costs across the whole term.

Working out the effective rent

Effective rent is the average annual cost of occupation once every incentive has been accounted for. A simple version of the calculation is total rent payable over the term, divided by the number of years.

Take a five-year lease at £36,000 a year with nine months rent free. Rent is payable for four years and three months, so the total is £153,000, or £30,600 a year across the term. If the landlord also contributes £15,000 towards the fit-out, that sum usually needs to be modelled separately rather than netted off: it is frequently paid against invoices, released in stages, and may be repayable if the tenant leaves early.

The simple average flatters the deal slightly, because the rent-free months arrive at the beginning. Money saved in year one is worth more than the same money saved in year five, and a discounted calculation will produce a marginally higher effective figure. Any comparison between two properties should also carry the same assumptions about timing.

A workable model lists, at minimum:

• the headline rent and the review pattern, whether open market, upward-only, index-linked or fixed
• service charge and insurance rent, which are almost never waived
• business rates, which remain the occupier's liability whatever private arrangement exists between landlord and tenant
• the rent deposit, any personal guarantee, and the conditions attached to both
• repairing obligations, and whether a schedule of condition limits them
• the cost of removing or reinstating fit-out at the end of the term

Incentives that flatter weak terms

Not every concession is a concession. Four structures deserve particular scrutiny.

A long rent-free period attached to a term with no break transfers the risk of a poor location onto the tenant for the full duration. Spread over five years, eighteen months free looks handsome; it looks considerably less so in year four, when the market has moved and the tenant cannot leave.

A stepped rent can perform the same trick in reverse. A low opening rent, followed by an uplift above the prevailing market level in year three, may cost more over the term than a flat rent with a shorter incentive.

An incentive offered in lieu of a schedule of condition is rarely a fair exchange. In an older building, a properly drawn schedule limiting the tenant's repairing liability can be worth more than several months of rent, particularly where the roof, plant or structure is near the end of its life.

Finally, contributions dressed as rent-free periods rather than cash tie the tenant to the landlord's timetable for works. If the money can only be drawn once the unit is handed over in a particular condition, the incentive is partly a promise about someone else's programme.

Testing the package against a slower year

Most business plans assume that trade improves. A lease should be tested against the opposite. Model a fifteen or twenty per cent fall in turnover in year two and ask what the lease looks like then. In the typical structure, the rent-free months have already been consumed, and the tenant meets full rent in precisely the period when cash is tightest.

Where that exposure is uncomfortable, three responses are worth putting on the table. The first is a split incentive: part of the rent-free period at commencement and part following the first review, so that relief arrives when it may be needed. The second is a tenant-only break at year three, with a modest penalty accepted in exchange, which converts an uncontrollable risk into a priced one. The third, in retail and hospitality in particular, is a turnover-related element, which aligns the landlord's return with the occupier's trading reality.

Break options and the price of exit

A break clause is only as good as its conditions. Common requirements include no arrears of rent or service charge, giving vacant possession, and notice served within a narrow window, sometimes six months ahead. Each is manageable with a diary and a cash-flow forecast.

The provision that undoes the value of a break is a repayment clause requiring the tenant to return the benefit of the rent-free period on exercise. An option to repay nine months of rent in order to leave is not an exit; it is a second negotiation conducted from a weaker position.

Bringing the package together

Once the terms are priced, negotiation becomes a question of ranking. Tenants should be willing to trade headline rent, which the landlord values for the reasons above, for terms that protect the business: a schedule of condition, a workable break, a service charge cap, or a restriction on the landlord's ability to relocate the tenant.

Whatever is agreed must appear in the lease or in a side letter. Confirm the dates of the rent-free period, the conditions attached to any fit-out contribution, and the tax treatment of every element with an accountant before exchange. Ask the solicitor to check that the incentive is not conditional on completion of works by a date that may slip, and that rent review provisions do not use the headline figure in a way that quietly reverses the benefit.

The incentive on the board is the opening of the conversation. The effective rent, tested against a bad year, is where the conversation should end.
