Public contracts won
SG Electrical Solutions Ltd has 3 public sector contract awards on record; the ones with their own published value total £111K, from 2018 to 2025. Source: Contracts Finder and Find a Tender award notices. For 1 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 plumbing and heating companies
