Commercial Lease Negotiation: How a Surveyor Protects You Before You Sign

Most of the money in a commercial lease is won or lost before anyone signs. Once the heads of terms are agreed and the lease is drafted around them, your repairing obligations, your exit costs and your flexibility are largely fixed for the term. That's why the negotiation stage, not the signing, is where a surveyor earns their fee. Here's what actually matters, and how to protect your position before you commit.

Why the lease terms decide what you pay

A commercial lease is a long financial commitment, and its clauses quietly allocate risk between you and the landlord. Rent is the number everyone focuses on, but the repairing covenant, the reinstatement obligation, the break clause and the rent review can each cost more than a few months' rent if they go the wrong way. Once the lease is signed, those terms are set for the term.

The window to influence them is the heads of terms stage, before solicitors draft the lease around what's been agreed. Turning up to that stage with proper advice is how you avoid inheriting costs that were never really yours.

This is general information, not legal advice. Take advice on your specific lease and situation.

Repairing obligations: the biggest hidden cost

Most commercial leases are full repairing and insuring (FRI). That means the tenant is responsible for keeping, and handing back, the property in good repair, often regardless of the state it was in at the start. On an older building, that can make you liable for pre-existing wear, tired services and defects you had nothing to do with.

There is room to negotiate here. You can push for the repairing obligation to be qualified, for example limited by reference to a Schedule of Condition, or for specific items (a worn roof, ageing plant) to be excluded or shared. Whether you get any of that depends on the market and your covenant strength, but you won't get what you don't ask for.

Cap it with a Schedule of Condition

The single most effective protection for a tenant is a Schedule of Condition: a dated, photographic record of the property's exact state, agreed and annexed to the lease. The repairing covenant is then read subject to that record, so you can't be charged at lease end to put the building into better condition than you took it.

It has to be done before you sign, because it can't be created retrospectively. Commissioned early, it typically costs a fraction of the dilapidations claim it prevents, which is why it's the first thing a good surveyor will raise when you're taking on a repairing lease.

Your dilapidations exposure at lease end

The bill for your repairing obligations usually lands as a dilapidations claim when the lease ends. What you negotiate at the start directly shapes that final figure. A qualified repairing covenant and a Schedule of Condition can cut it dramatically, and even without them, Section 18 of the Landlord and Tenant Act 1927 caps damages at the amount the disrepair reduces the value of the landlord's interest.

Thinking about the exit at the entrance feels premature, but it's exactly when you have the most leverage. A surveyor who handles dilapidations can tell you what your draft lease is likely to cost you to walk away from.

Reinstatement and alterations

If you plan to fit out the space, the lease's reinstatement provisions decide whether you'll have to strip it all back out at the end. That can be a substantial, easily overlooked cost. Negotiate clarity now on what alterations are allowed, what has to be reinstated, and whether the landlord might accept keeping improvements that add value. Recording the pre-fit-out condition supports this too.

Break clauses and flexibility

A break clause gives you a way out, but only if you can actually operate it. Break clauses are notoriously easy to trip up on: conditions requiring vacant possession, full compliance with covenants or payment of all sums can invalidate a break if you fall short. Negotiate the conditions to be as clean and achievable as possible, ideally break subject only to paying the rent and giving vacant possession, and diarise the notice dates carefully. A conditional break you can't safely exercise is worth very little.

Rent review and the RICS lease code

How and when the rent can change matters as much as the opening figure. Upward-only reviews, the review basis and the frequency are all negotiable. The RICS Code for Leasing Business Premises sets out what fair, balanced lease terms look like, and it's a useful benchmark to hold a landlord's draft against, because parts of it are mandatory for RICS members acting on a letting.

Security of tenure and renewals

Business tenants in England and Wales usually have a statutory right to renew their lease under Part II of the Landlord and Tenant Act 1954, unless the lease is "contracted out" of that protection. Whether you're inside or outside the Act is a significant point that's often decided at heads of terms and easy to miss. Your solicitor leads on this, but it should be a conscious decision, not a default.

Where a surveyor fits, alongside your solicitor

Your solicitor drafts and advises on the legal mechanics. A RICS-qualified building surveyor advises on the physical and cost side: the condition of the building, what the repairing covenant will actually cost you, whether to limit it with a Schedule of Condition, and your likely dilapidations exposure at the end. The two work best together, and the earlier you bring the surveyor in, ideally at heads of terms, the more they can protect.
