Public contracts won
SN Heating & Plumbing Ltd has 5 public sector contract awards on record; the ones with their own published value total £223K, from 2022 to 2025. 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. 3 of these were matched by the company's exact name because the notice gave no company number.

Filing notes for plumbing and heating companies
