Public contracts won

Ac1 Electrical Services Limited has 4 public sector contract awards on record, from 2023 to 2026. Source: Contracts Finder and Find a Tender award notices. For all 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. 1 of 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.
