Fitting out a commercial unit (partitions, flooring, lighting, kitchens, branding) can cost a small business a great deal. Whether you can reduce that cost depends largely on what your lease and heads of terms say, and on what you negotiate before signing. Here is how fit-out costs work in commercial leases in England and Wales, and where the savings lie.
Who pays for the fit-out?
In most commercial leases, the tenant carries out and pays for its own fit-out, the lease typically requires the tenant to keep and (on a full repairing and insuring, or "FRI", lease) repair the premises, and any fit-out is at the tenant's cost. So the starting point is usually that fit-out is the tenant's responsibility.
But the lease is the product of negotiation, and there are well-established ways to share or reduce the burden, if you raise them before you sign.
Levers to reduce the cost (negotiated up front)
- Rent-free period. Landlords often grant a period of reduced or zero rent to allow time and budget for fit-out. This is one of the most common ways the cost is effectively shared.
- Landlord's contribution. A landlord keen to let space may offer a capital contribution towards fit-out works, especially in a soft market or for a strong covenant tenant.
- Category A / Category B split. In many lettings the landlord delivers the space to a basic standard ("Cat A") and the tenant fits out to its own needs ("Cat B"). Clarify exactly what the landlord is providing.
- Taking space already fitted. A unit with an existing fit-out, or a shorter lease of pre-fitted space, can avoid much of the cost.
These points are usually agreed in the heads of terms, once the lease is signed, your bargaining power is largely gone.
Don't overlook the legal mechanics
- Consent to alterations. Fit-out works are usually "alterations", and the lease normally requires the landlord's consent, often documented in a licence to alter. Doing works without required consent is a breach.
- Reinstatement. Leases frequently require the tenant to remove its fit-out and reinstate the premises at the end of the term. That is a future cost worth negotiating (for example, limiting what must be removed).
- Statutory and safety rules. Fit-out works may engage building regulations, planning, fire safety and (for landlords and contractors) construction-related duties.
Risks of not paying or cutting corners
If you have agreed to carry out or pay for works and do not, you risk being in breach of the lease, exposing you to the landlord's remedies, potentially including damages or, in a serious case, forfeiture. Cutting corners on consents or safety can store up bigger problems later.
Practical approach
- Negotiate rent-free periods, contributions and the Cat A/Cat B split in the heads of terms.
- Get the licence to alter in place before starting works.
- Pin down reinstatement obligations early to limit end-of-term cost.
- Budget realistically and take professional (legal and surveying) advice before committing.
Key takeaways
- Fit-out is usually the tenant's cost, but this is negotiable, especially before signing.
- The main levers are rent-free periods, landlord contributions, and the Cat A/Cat B split.
- Fit-out normally needs the landlord's consent (a licence to alter), and watch the reinstatement obligation.
- Failing to meet agreed obligations is a breach of the lease, negotiate and document instead.
