Fire-safety context
Ownership value and premises risk answer different questions
For flat owners and landlords
Fire-safety duties depend on the building, common parts, use, control and applicable law—not the sale value. Start with the guide for blocks of flats or check whether an assessment is required.
For buyers and professionals
Market data cannot reveal compartmentation, fire-door, alarm or external-wall conditions. Transactions and refurbishment may require separate technical enquiries.
