Public contracts won

RTC Building Contractors Limited has 2 public sector contract awards on record (2024). 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. These were matched by the company's exact name because the notice gave no company number.

Filing notes for property development companies

Many property development companies are single-project vehicles. Stock of land and buildings sits on the balance sheet as work in progress until sale, and a company that has finished its project may become dormant rather than close.
