CAT A Reinstatement: What London Landlords Actually Check

Every commercial tenant returning a demise at lease exit faces a CAT A reinstatement inspection. This guide explains what landlords' surveyors actually check, the defects that trigger dispute, typical reinstatement costs, and how to pass the joint inspection first time.

What CAT A reinstatement means

Tenants at lease exit must return the demise to the condition specified in the lease — typically landlord's original CAT A specification. This reverses everything the tenant added during CAT B fit-out: partitioning, branded joinery, tea points, AV containment, flooring, special lighting, and any M&E alterations.

CAT A reinstatement is a separate product to dilapidations. Dilapidations is the valuation of the reinstatement obligation; CAT A reinstatement is the physical works to discharge it.

What landlord surveyors inspect

Joint inspection on completion typically covers:

Flooring

Ceilings

Partitioning and walls

M&E

WCs and tea points

Reception and entrance

Documentation

Common failure points

The most frequent items that fail joint inspection:

  1. Wall-finish shadows

    Branded signage fixings filled but ghosted paint outlines visible. Remedy: full two-coat redecoration of affected wall.

  2. Access-floor panel damage

    Tenant screws, chips and non-standard panels from cable-pulls. Remedy: replace damaged panels with CAT A stock.

  3. Ceiling grid distortion

    Ceiling grid bowed where tenant partitioning transferred load. Remedy: re-level grid, replace damaged tiles.

  4. Incomplete fire-stopping reinstatement

    Cable-tray removals leave unsealed compartment penetrations. Remedy: FIRAS-certified re-stopping.

  5. Missing certificates

    EICR, emergency lighting, fire-stopping not formally issued. Remedy: commission tests and retro-issue certificates.

Typical costs

The joint inspection

The inspection format:

  1. Pre-inspection walk

    Tenant's contractor does a snag walk 48 hours before joint inspection — addresses defects pre-landlord visibility.

  2. Joint inspection

    Landlord surveyor + tenant's PM walk the demise room by room. Defects noted on snagging list.

  3. Defects remediation

    Agreed defects remedied within 1–2 weeks. Re-inspection scheduled.

  4. Handover sign-off

    Landlord surveyor signs acceptance letter. Dilapidations obligation discharged.

FAQs

Do we need to reinstate CAT A+ if the landlord added it?

Depends on the LTA. Usually CAT A+ is deemed part of the CAT A standard, so the reinstatement obligation is to the CAT A+ standard. Review your LTA carefully.

Can we settle dilapidations without physical reinstatement?

Yes — most London commercial leases permit settlement by cash payment instead of physical works. The landlord then either does the works themselves, retains the payment as compensation, or lets the space in its current state. Settlement is typically 40–70% of a priced reinstatement scope.

How long before lease expiry should reinstatement start?

6–8 weeks for standard 5,000–10,000 sqft reinstatement. Longer on complex dilapidations. Starting too late forces rushed settlement at the landlord's figure.
