Public contracts won
Efs Systems (UK) Ltd has 9 public sector contract awards on record; the ones with their own published value total £868K, from 2024 to 2026. Source: Contracts Finder and Find a Tender award notices.

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.
