A dispute arose over service charges under a commercial lease. The tenant refused to pay certified charges, claiming they were excessive. The Supreme Court held that the landlord's certificate was conclusive as to the sum payable, but the tenant could later dispute underlying liability. This established a 'pay now, argue later' interpretation of conclusive certification clauses.

Facts

Sara & Hossein Asset Holdings Ltd (S&H), a property investment company, was the landlord of commercial premises leased to Blacks Outdoor Retail Ltd (Blacks), a retail chain. Under the leases (2013 and 2018), the tenant was required to pay a service charge calculated in accordance with Schedule 6. Paragraph 3 of Schedule 6 provided that the landlord’s certificate as to the total cost and sum payable by the tenant was conclusive ‘in the absence of manifest or mathematical error or fraud’.

For the 2017-18 service charge year, S&H certified over £400,000 as payable, a dramatic increase from approximately £55,000 the previous year. Blacks refused to pay, claiming the charges were excessive and included unnecessary items falling outside the lease terms. S&H sought summary judgment for the certified amounts.

Issues

The central issue was the proper interpretation of the certification provision in paragraph 3 of Schedule 6. Specifically:

S&H’s Position

The landlord contended that its certification was conclusive as to both the total cost and the sum payable by the tenant, subject only to the permitted defences of manifest or mathematical error or fraud.

Blacks’ Position

The tenant argued that the certificate was conclusive only as to the costs incurred by the landlord, not as to the tenant’s underlying liability to pay those costs.

Judgment

The Supreme Court, in a majority judgment delivered by Lord Hamblen (with Lord Hodge, Lord Kitchin and Lord Sales agreeing), adopted a third interpretation not advanced by either party. Lord Briggs dissented.

The Majority’s Interpretation

Lord Hamblen found that neither party’s interpretation was satisfactory when subjected to an iterative analysis. He stated:

Adopting an iterative approach, neither party’s interpretation is satisfactory. S&H’s case fits well with the wording of the certification provision but not the wider contractual context. It suits the landlord’s commercial purpose but produces surprising and uncommercial consequences. Subject only to the permitted defences, it is a pay now, argue never regime. Conversely, Blacks’ case is supported by the internal context of the contract but not the certification of the sum payable by the tenant.

The majority held that the certificate is conclusive as to what must be paid under the Schedule 6 regime, protecting the landlord’s cashflow. However, payment does not preclude the tenant from subsequently disputing liability:

Payment of the certified sum does not, however, preclude the tenant from thereafter disputing liability for that payment. This gives full effect to the tenant’s inspection rights under paras 8 and 11 of Part 1 of Schedule 6 and any arguable disputes identified thereby.

Lord Hamblen summarised:

In summary, the certification provision should be interpreted as being conclusive as to the service charge sum payable by the tenant but not as to the underlying liability for the service charge. The tenant is entitled to bring a claim seeking repayment of a cost which it is contended had been improperly charged. It is a form of pay now, argue later provision, a contractual arrangement which is commonly found.

The Dissent

Lord Briggs dissented, arguing there was no warrant in the lease for the majority’s ‘pay now, argue later’ construction. He stated:

My difficulty with the pay now, argue later solution which Lord Hamblen proposes (and with which my other colleagues agree) is that I can discern no warrant for it at all in the lease. Furthermore it is a solution which, if desired by the parties, they could so easily have provided in clear terms.

Implications

This decision provides important guidance on the interpretation of conclusive certification clauses in commercial leases. It establishes that such clauses create a ‘pay now, argue later’ regime rather than extinguishing the tenant’s right to challenge underlying liability. The case also provides authoritative guidance on the meaning of ‘manifest error’, confirming it means an error that is ‘obvious or easily demonstrable without extensive investigation’. The decision balances landlord cashflow protection with tenant rights to dispute improper charges, offering a commercially sensible interpretation that the parties themselves had not articulated.

Verdict: Appeal allowed in part. The Court of Appeal’s summary judgment for the landlord was upheld, but the tenant’s right to pursue its counterclaim disputing underlying liability was preserved. The landlord’s certificate is conclusive as to the sum payable under the service charge mechanism, but does not preclude the tenant from subsequently claiming repayment of improperly charged costs.
