Listed buildings demand specialist assessment.
Authentic materials, heritage contractors and conservation requirements drive rebuild costs far above standard construction. A desktop assessment will miss the gap entirely.
Authentic materials and conservation requirements drive up rebuild cost.
Under the Planning (Listed Buildings and Conservation Areas) Act 1990, rebuild must replicate original style and materials - a legal obligation that generic desktop calculators systematically miss.
Grade I & II*
The highest-significance categories often require Heritage England involvement and specialist heritage contractors.
Heritage Materials
Lime mortar, handmade brick, natural stone and historic timber all carry premiums standard rates miss.
On-Site Only
Desktop assessment cannot capture these uplifts - only a physical inspection produces a defensible figure.
Authentic materials, conservation requirements and period finishes all affect rebuild cost.
Under the Planning (Listed Buildings and Conservation Areas) Act 1990, rebuild must replicate original style and materials. That legal obligation transforms the cost picture: lime mortar, handmade brick, heritage contractors, conservation consents and extended timescales all carry significant premiums over standard construction rates.
Generic desktop calculators apply standard BCIS rates and systematically miss every one of these uplifts. For complex Grade I properties the gap between a desktop figure and a defensible declared value can exceed 100%.
Get a Specialist AssessmentListed Building Categories
Grade I
Highest significance - only 2% of listed buildings. Rebuild requires the most exacting materials match and Heritage England involvement.
Grade II*
Particularly important buildings - 6% of the list. Often require specialist heritage contractors and conservation officer input on every element of rebuild.
Grade II
The most common category - 92% of listed buildings. Still subject to listed building consent and material-authenticity obligations that standard assessors routinely overlook.
The only defensible method for a listed property.
Booking and pre-survey research
We review planning history, listing description and any available drawings before attending. Pre-survey research means inspection time is spent on the building, not administration.
Physical site inspection
A RICS-regulated surveyor attends the property and records construction type, materials, condition and specialist features that inform the cost build-up.
Heritage-calibrated cost build-up
Costs are built from elemental rates calibrated for heritage construction - not standard BCIS tables. Professional fees, consents, VAT and programme premiums are each priced separately.
Broker-ready report
The final report sets out the declared rebuild cost with a full methodology note, ready for submission to your insurer at renewal.
Built for listed buildings, not adapted from standard practice.
On-Site Inspection
Every listed building assessment is carried out on site. Desktop methods cannot account for heritage materials, specialist trades or the physical condition of the fabric.
