Public contracts won
Buchanan & Curwen (Leatherhead) Limited has 4 public sector contract awards on record, from 2018 to 2024. Source: Contracts Finder and Find a Tender award notices. For 2 of them the published figure is a shared or multi-year ceiling (a framework place, a multi-supplier award, or more than a small company could hold alone), so no value is shown. These were matched by the company's exact name because the notice gave no company number.

Filing notes for electrical contractors
Electrical contracting companies are often a director plus a van and tools. Most fall within the micro-entity rules, so the accounts filed at Companies House are short, and the CT600 carries the tax detail.
