Rent reviews

Open-Market, RPI, Fixed: Read Once, Watched Forever.

Every review surfaced with its mechanism, date and notice period, so the negotiation starts when it should, not when the demand lands.

Negotiation starts before the trigger letter.

A 12-month notice period means starting prep at 14 months. We surface the runway so leadership signs off the position before the landlord serves.

  1. T − 14 months
    Position drafted

    Comparables gathered, P&L sensitivity modelled, internal sign-off requested.

  2. T − 12 months
    Notice period opens

    Lease's contractual notice window opens. The landlord can trigger from this point.

  3. T − 3 months
    Surveyor briefed

    Independent surveyor brief issued, evidence pack pre-staged.

  4. T = 0
    Review date

    Reviewed rent agreed and recorded. Evidence + comparables stored against the review for the next cycle.

Every reviewed rent, written atomically.

When the new rent is agreed, the change lands in the audit log with the supporting comparables attached. The next review starts with the trail intact.

Audit log

Every review, every mechanism.

A 'capped and collared' review with a CPI floor and an open-market ceiling is a normal British lease. We read all of it.
  • Mechanism classified

    Open-market, RPI-linked, CPI-linked, fixed uplift, hybrid (collared/capped). Each review tagged with its mechanism for portfolio-level analytics.

  • Review dates

    Pulled from both the rent schedule and any explicit review clause. We cross-check the two and flag inconsistencies for human review.

  • Caps & collars

    Floor / ceiling captured as numbers. Useful for portfolio modelling: what's the cap exposure across 200 leases at +20% inflation?

  • Pre-review workflow

    12-month notice period? We warn 14 months out so your negotiating position is prepared before the trigger letter lands.

  • Post-review evidence

    Reviewed rent, agreement date, supporting comparables, uploaded against the review so future reviews benefit from the trail.

  • Tenant + landlord views

    Tenant: 'how much could this go up?'. Landlord: 'how much can I push?'. Same data, two dashboards.

Anyone who'd rather not be surprised by a rent demand.

The rent review you forgot about is the one that costs the most.

Portfolio modelling: open-market exposure vs RPI-floor exposure across 80 leases. Senior leadership gets a single P&L sensitivity number.

Open-market exposure is a different valuation question than RPI exposure. Portfolio split by mechanism shows in one query.
