**How to approach a UK upward-only [rent review](/glossary/rent-review) without giving the landlord the entire upside.**

## TL;DR

- Start preparation 12–18 months before the review date.
- Build the comparable evidence early — landlords have the data advantage.
- Negotiate the assumptions and disregards in the review clause, not just the rent.
- Time-of-the-essence procedural traps can lose the review by default.
- Arbitration is slow and expensive — settle in negotiation where possible.

## Why UK rent reviews matter

UK Class A leases of 10+ years almost universally include 5-yearly upward-only rent reviews. Get the review wrong and the next 5 years of rent are over-market with no possibility of correction. The structural asymmetry of upward-only is the single largest risk in a long UK lease — and the largest negotiating opportunity at lease signing.

## Comparable evidence

Build the comparable evidence early. Landlords with portfolio scale have superior data; tenants must compensate with research depth and broker engagement. Run a market benchmarking exercise 12–18 months before the review date covering recent lettings, sublettings, and renewals in the same building, the same submarket, and comparable Class A buildings.

## Assumptions and disregards

The review clause defines what the hypothetical lease being reviewed looks like. Key tenant-friendly disregards: tenant's improvements, tenant's goodwill, tenant's occupation. Key tenant-friendly assumptions: a willing landlord and tenant, vacant possession, market terms. Negotiate these at lease signing, not at review.

## Procedural traps

Many review clauses include time-of-the-essence provisions on the tenant's response. Miss the response window and the landlord's quoted rent often becomes binding. Calendar the trigger dates. Engage a UK rent-review specialist 6 months ahead.

## When to arbitrate

Arbitration is slow (12–18 months), expensive (GBP 30–80k each side), and binding. Most reviews settle in negotiation. Arbitrate only if the landlord's quote is materially above your benchmark and you have credible expert evidence to support a substantially lower number.

## Frequently asked questions

****Can I avoid upward-only?****
: Rarely on a Class A lease in the City or West End. Some landlords accept collared structures (collar at passing rent, cap at +X%) but only at lease signing — never at review.

****Should I use the same broker for renewal and review?****
: Often a different specialist is appropriate. Rent-review work requires deep [RICS](/glossary/rics) Red Book valuation experience; transactional brokers are not always positioned to do that work.
