Why: Confirms public sewer connection, water supply, and whether drains run under the property.

Why: Rare but brutal: some parishes can bill freeholders for church chancel repairs. A one-off indemnity is cheap insurance.

Why: Verifies seller is registered proprietor, shows restrictions, covenants, easements, and charges.

Why: Check title plan against physical boundaries. Disputes with neighbours are disclosable and kill future sales.

Why: Unauthorised extensions or missing building regs certificates can force costly remediation or demolition.

Why: Extensions or conversions without permission can trigger enforcement for up to 10 years (4 for operational dev).

Why: Live enforcement = you inherit the problem. Deal breaker unless priced in heavily.

Why: Required from exchange (freehold) or check block policy (leasehold). Flood/subsidence areas can make insurance unaffordable.

Why: Confirms lender support. BTL and HMO need specialist products with higher stress tests.
