Awards are collected from official public procurement notices and deduplicated so one procurement counts once. Supplier names are grouped across their published spellings: case and punctuation are ignored, and “Ltd” is treated as optional because buyers routinely leave it off. Everything else that marks a different organisation is kept — an LLP, a plc, a CIC and a Teoranta are separate businesses from a Ltd of the same name, as are a parent and a named subsidiary, and none of them are merged here. Where another entry differs from this one only by legal form or a bracketed qualifier it is listed above as possibly the same organisation — a hint for the reader, never a merge: figures are per legal entity and never combined. Value is attributed only where the notice is explicit: the supplier's own itemised amount, or the whole value where they were the sole named supplier. Awards naming several suppliers without a published split are counted and marked shared, never valued, and a framework ceiling is never treated as money any one appointed supplier won. Sterling and euro are never added together. The linked source notice is authoritative.
Company pages are for organisations. If this page profiles you as an individual — a sole trader or an individual contractor — you can ask for it to be withheld: see how.
