How to Review a Commercial Lease Service-Charge Cap in England

Loveday is under pressure to sign because the agent treats a dwelling rule as a ceiling on this workshop. The problem is a costly gap between the heads and the draft. Open clause 5.4, not the Slack note of 8 October 2026, then narrow the cap or walk.

In October 2026 Loveday, ops at Lizard Kiln Ltd, reads Unit 2 at Coinagehall Yard, a twelve-person workshop in Helston. Landlord Coinagehall Estates Ltd, English law, courts of England and Wales. Heads of 18 September 2026 cap the charge at £4,800, and the agent wants Friday 16 October 2026. This is a field how-to from that unit desk, not a tour of the whole lease.

The typical mistake is hidden in that Slack. The agent treats dwelling reasonableness rules as a hard ceiling, a surveyor’s exceptional label as automatically outside, and the vacant unit as a share the others absorb. The note also treats the certificate as the end of liability.

In Sara and Hossein the Supreme Court read a conclusive certificate as conclusive of the sum payable, not of liability. Lord Briggs dissented, and clause 5.6 uses different words. For example, the RICS 2nd edition cites the Court of Appeal number for that pay-now reading.

How to review the missing statutory cap on Unit 2

No statute caps Unit 2. Section 18, read on 11 October 2026, defines a service charge as a sum payable by a tenant of a dwelling. Write that down. The control is clause 5.4, and it is not a hard £4,800.

Section 53 of the 2024 Act is prospective and would still say tenant of a dwelling. The 2003 regulations set a £100 limit in that regime. Do not put £100 on clause 5.4. No dwelling sits in this packet: the draft lease, the heads, and the side letter.

The RICS standards page dates the 2nd edition from 31 December 2025, including 31 December 2026 year ends. The PDF cannot override the lease. Harper James still cites 2018. The office lease checklist covers the rest of the lease. A break, the repairing covenant, and a terminal schedule are other articles.

Compare the hard heads with the indexed cap before you rely on £4,800?

The heads and the side letter are a hard £4,800. Clause 5.4 is indexed. Do not merge them. The side letter is personal to Lizard Kiln Ltd, with no index, no exclusions, and it is not annexed. The risk is signing the heads while the lease moves.

Clause 5.4 caps the tenant’s yearly sum at £4,800. It rises on each anniversary by the Retail Prices Index, then takes insurance, utilities, and certified exceptional spend outside. No base month and no CPI or CPIH substitute is printed.

Womble Bond Dickinson, 20 March 2026, calls an RPI uplift usual. That is not a base month. The ONS page and the GOV.UK response put a CPIH-method change at February 2030, not before. Do not say RPI has stopped, and do not compute a future £4,800.

LexisNexis, 21 May 2026, says a personal side letter will not bind successors. Do not decide a 1954 Act renewal. The yearly-rent index is another article. In practice, edit clause 5.4 or walk if you negotiate a service charge cap on a commercial lease in the UK.

Red flag checklist for carve-outs that sit outside the cap

Insurance, utilities, and certified exceptional expenditure sit outside clause 5.4 because the clause says so. Service Costs already include insuring the Building, utilities, capital spend, and costs the landlord incurs in its discretion. That double layer is the red flag. Do not decide the roof email.

The 2 October 2026 email is not a certificate. It writes £28,000, a 40 percent share of £11,200, insurance of £2,100, electricity of £900, and a £6,000 roof. Do not decide the £6,000, and do not treat those pounds as a Helston norm.

RICS principle 3.8 would leave out void costs, and a sweeper is read narrowly. Stevens and Bolton, 12 February 2026, says that standard cannot override the lease. Indexation here is RPI, not CPI. Insurance rent is another article.

How to review apportionment when Unit 4 is vacant

Unit 4 is vacant. Clause 5.1 is a fair proportion as the landlord’s surveyor shall determine, with no percentage, no floor area, no matrix, and no sentence that the landlord bears the void. Do not invent a Helston percentage.

RICS asks for a matrix and says landlords should meet unlet costs, while the lease stays paramount. Clause 5.1 does not make the landlord pay Unit 4. Check the email’s 40 percent against that silence. The cap does not swallow the carve-outs.

Which certificate is conclusive of payment or of liability?

Clause 5.6 says a certificate by the landlord’s surveyor as to the service charge payable by the tenant shall be final and binding on the tenant save in the case of manifest error. It does not say pay now, argue later. It names no mathematical error, no fraud, no inspection right, and no later claim. Do not paste the Blacks lease onto Unit 2.

In Sara & Hossein [2023] UKSC 2, 18 January 2023, Lord Hamblen at paragraphs 51 to 57 treated the Blacks certificate as conclusive of the sum to be paid, not of liability. Lord Briggs dissented. Paragraph 45 says other contracts are little help. Do not carry that result onto clause 5.6.

Blacks certified total cost and the sum payable, and it allowed inspection. Clause 5.6 does not. The RICS PDF’s [2020] EWCA Civ 1521 is the Court of Appeal, not [2023] UKSC 2. The case page is not the holding. Do not decide a withhold or a repayment claim.

Checklist before signing: narrow this cap or walk

Loveday writes five marks before Friday 16 October 2026. No statute caps this commercial unit. Clause 5.4 is an indexed cap with carve-outs, not the hard figure in the heads or the side letter. Apportionment is a fair proportion with no matrix and no vacant-unit sentence. The certificate is final and binding save for manifest error, not the pay-now wording. Then she narrows the cap or does not sign.

If you stay, use a hard figure or a base month, keep the carve-outs inside, put Unit 4 on the landlord, and allow a stated challenge. If those edits are refused, walk. Consent to assign, peaceable re-entry, and insurance rent are other articles.

Before you sign, verify the five marks and escalate the gaps. Follow heads → clause 5.4 → side letter → carve-outs → vacant unit → certificate → narrow or walk. Use document analysis and the England lease review tool.
