Specialist assessments for every block type.

When a block is underinsured, the average clause reduces every claim - and every leaseholder shares the consequence. A specialist assessment establishes the correct declared value and protects all parties under the policy.

Specialist Reinstatement Cost Assessments for blocks of flats across the UK.

Blocks of Flats

Why block assessments are complex.

Blocks of flats involve cost elements that generic calculators and market-value approaches overlook entirely. Shared structures, communal services and leaseholder obligations create a unique risk profile that requires specialist assessment.

  • 01Shared structures: External fabric, roof, foundations and structural elements shared between all leaseholders must be valued at full rebuild cost, not apportioned.
  • 02Communal services: Lifts, boiler plant, communal lighting, entry systems and shared M&E infrastructure all carry reinstatement costs that generic tools miss.
  • 03Leaseholder obligations: A wrong declared value triggers the average clause and reduces every leaseholder's claim, not just the freeholder's. The legal exposure falls on whoever arranged the insurance.

Common questions about Reinstatement Cost Assessments for blocks of flats.

Blocks of flats carry rebuild costs that generic online calculators miss entirely communal areas, lifts, shared services, external fabric, professional fees, and VAT on partial-damage repairs. A RICS-regulated Reinstatement Cost Assessment captures every cost layer specific to your block. When multiple leaseholders share one insurance policy, a wrong declared value puts every one of them at risk simultaneously.

If the declared value in a buildings insurance policy is inadequate at claim time, the insurer applies the average clause and reduces every payout proportionally. A block insured for 70% of its true reinstatement cost has every claim escape of water, fire, subsidence paid at 70p in the pound. An up-to-date Reinstatement Cost Assessment (rebuild cost assessment) is the primary protection against this.

A RICS-regulated Reinstatement Cost Assessment for a block covers demolition and site clearance, structure, external envelope, communal areas, lifts, building services, professional fees, statutory fees, and VAT where applicable. It produces a single declared value covering the full cost of rebuilding the block from cleared ground the figure your insurer needs at renewal.
