Public contracts won
Avon Construction Limited has 19 public sector contract awards on record; the ones with their own published value total £1.1M, from 2016 to 2026. Source: Contracts Finder and Find a Tender award notices. For 7 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. 15 of these were matched by the company's exact name because the notice gave no company number.

Filing notes for civil engineering contractors
Civil engineering contractors usually carry plant and machinery, so capital allowances (the annual investment allowance and the main pool) do much of the work in the corporation tax computation.
