Why a lender cares about searches

A lender is not buying the house, it is lending against it, and its interest is narrow: is there anything on or under this title that would make the security hard to sell. Three searches answer most of that question.

Local authority

The local search covers planning history, building regulations, road adoption and the entries a local authority holds against the property. It is the search most likely to delay a file, because turnaround is set by the council rather than by the firm.

Drainage and water

Confirms whether the property is connected to mains water and public sewer, and whether a public sewer runs within the boundary. A sewer under a proposed extension is a common late surprise.

Environmental

Screens contaminated land, flood risk, ground stability and nearby landfill. Lenders increasingly treat flood risk as a valuation question rather than a legal one, which is why the report reaches both the file and the surveyor.

A cash buyer may decline all three. A buyer with a mortgage generally cannot, and a quote that omits them is not comparable to one that includes them.
