The basics
What is a commercial reinstatement cost assessment?
It’s the cost of rebuilding your property from scratch, the structure, the services, professional fees, and today’s building regulations. That’s the figure your insurance should be based on, and it’s not the same as market value.
The gap matters. Most policies apply a condition of average, so if you’re insured for less than the true rebuild cost, the insurer can cut your claim by the same proportion. RICS recommends a fresh assessment every three years to keep that figure honest.
It follows exactly the same principles as any building reinstatement cost. The difference for commercial property is scale, construction type and the specialist systems that a full rebuild has to replace.
Common challenges
Where commercial cover slips out of step.
Commercial rebuild costs have outrun old estimates: BCIS data shows construction material prices are up more than 20% since 2020 (BCIS). Under a policy’s condition of average, a sum insured that has not kept pace can see even a partial claim reduced proportionally.
Costs outrun index‑linking
Material and labour inflation has pushed commercial rebuild costs well beyond what standard index‑linking captures, widening the gap each year. A periodic reassessment brings the sum insured back in line.
Calculators miss the detail
Generic calculators overlook mechanical and electrical services, specialist fit‑out, and external works. A professional valuation captures these directly, so the figure reflects the whole building.
Insurers expect RICS figures
More insurers and lenders now expect a verifiable, RICS‑regulated figure before agreeing terms. A dated estimate or calculator output rarely satisfies commercial underwriting.

Frequently Asked Questions.
Common questions about commercial reinstatement cost assessments, rebuild cost, and underinsurance.
What is a commercial reinstatement cost assessment?
A commercial reinstatement cost assessment is a professional calculation of the full cost of rebuilding a commercial property from the ground up if it were destroyed. It covers demolition and debris removal, the rebuild itself, mechanical and electrical services, professional fees, and compliance with current building regulations. It is the figure your buildings insurance sum insured should be based on, rather than the property’s market value.
Why is rebuild cost different from market value?
Market value reflects what a property would sell for, including the land, its location, and its income potential. Rebuild cost reflects only what it would take to physically reconstruct the building. For commercial property the two figures are often a long way apart, so insurance should always be based on rebuild cost, which is exactly what a reinstatement cost assessment establishes.
What happens if my commercial property is underinsured?
Most commercial policies contain a condition of average. If your sum insured is lower than the true rebuild cost, the insurer can reduce any claim payout in proportion to the shortfall, even for a partial loss. A building insured for 70% of its true rebuild cost, for example, may see a claim settled at around 70% of its value, leaving you to fund the rest.
How often should a commercial reinstatement cost assessment be reviewed?
RICS guidance recommends a full reinstatement cost assessment at least every three years, with index‑linking applied in the years in between. Commercial rebuild costs have moved sharply with material and labour inflation, so relying on index‑linking alone for longer can leave a significant underinsurance gap.
What types of commercial property do you assess?
We assess offices, warehouses and industrial units, retail premises, and mixed‑use buildings across the UK. Each assessment accounts for the specialist fit‑out, mechanical and electrical installations, and external works relevant to that type of building.
Will my insurer and broker accept the report?
Yes. Every assessment is RICS‑regulated and BCIS‑indexed, and is prepared to be broker‑ready and accepted by UK insurers as evidence of an accurate sum insured.
