Wales Commercial Maintenance Obligations (FRI Leases & Dilapidations)

In the Welsh commercial property sector, maintenance is rarely the landlord's problem. Unlike residential tenancies where strict "Fitness for Human Habitation" rules apply, commercial landlords and tenants in Wales allocate maintenance responsibilities entirely through the terms of the commercial lease.

The prevailing industry standard is to ensure the landlord receives a "clear rent" without any unexpected deductions for roof repairs or boiler replacements.

The Standard: The FRI Lease

The vast majority of commercial leases in Wales (whether for an industrial warehouse in Cardiff or a retail unit in Swansea) are drafted as Full Repairing and Insuring (FRI) leases.

Under an FRI lease, the commercial tenant assumes complete financial responsibility for keeping the property in good repair.

Single-Let Buildings vs. Multi-Let Buildings

The practical application of the FRI structure depends on how the building is occupied:

Single-Let Building (One Tenant Occupies the Whole Building)

• The tenant is directly responsible for physically maintaining and repairing the entire structure, including the roof, foundation, external walls, and all internal systems (HVAC, plumbing).
• If the roof blows off in a storm, the tenant must organize and pay for the repairs.

Multi-Let Building (Multiple Tenants in Offices/Retail Suites)

• It is impractical for a 2nd-floor office tenant to repair the building's roof. Instead, the landlord retains physical responsibility for repairing the external structure and shared common areas (lobbies, elevators, parking lots).
• However, the landlord recovers 100% of these costs from all the tenants via a Service Charge. The lease remains "effectively" FRI because the commercial tenant is still paying for the structural upkeep, just proportionately alongside the other tenants.

The Obligation to "Put and Keep" in Repair

A significant risk for tenants signing a Welsh FRI lease resides in the standard phrasing requiring the tenant to "put and keep the premises in good and substantial repair."

This legally obligates the tenant to not only maintain the property but to actually improve it if it was in poor condition on the day they took the keys. If the building was dilapidated when they signed the lease, they must spend the capital to bring it up to standard.

The Schedule of Condition Exemption

To mitigate this brutal liability, prudent commercial tenants will mandate a "Schedule of Condition" be legally annexed to the lease before signing. This is an extremely detailed photographic and written survey of the property's pre-existing flaws. The repair clause in the lease is then explicitly modified, stating the tenant is only obliged to keep the property "in no worse condition than evidenced by the attached Schedule of Condition," shielding the tenant from inherited capital replacement costs.

Dilapidations: The End of Lease Battle

The enforcing mechanism for commercial repair obligations is a highly litigious process in Wales known as Dilapidations.

Towards the end of the commercial lease, the landlord dispatches a specialized surveyor to inspect the premises against the stringent repair covenants within the lease. The surveyor produces a detailed "Schedule of Dilapidations" outlining every single defect, scratch, or unauthorized alteration, alongside the financial cost required to immediately rectify it.

• The tenant must normally execute the repairs themselves before the final day of the lease.
• If the tenant vacates without performing the repairs, they are in breach of contract. The landlord will execute the maintenance and sue the tenant (often holding back any rent deposit) for the entire financial cost plus damages for lost rent while the unit was unlettable during renovations.
