Tresco Heliport had a CAA Ordinary Licence (Number P677) that allowed flights for the public transport of passengers or for flying instruction as authorised by the licensee. The aerodrome was not licensed for night use.
Tresco's principal industry is tourism, and the heliport supported this by enabling scheduled helicopter service to and from the mainland. Without the presence of the heliport, visitors to the island from the mainland can now transfer to the inter-island boat service from the main island of St. Mary's. The heliport was owned and operated by Tresco Estates, who lease the island from the Duchy of Cornwall.
On summer weekdays the heliport received up to six flights a day from Penzance Heliport on the mainland, declining to two services a day in winter. Passengers were conveyed from the heliport to their resort or destination on a passenger carrying trailer drawn by a farm tractor. A footpath from one of the main landing beaches, at Carn Near, to the Abbey Gardens crosses the heliport landing field; it was closed by warning lights and bells a few minutes before a helicopter was due to land at the heliport, and opened again after the helicopter had taken off.
