Royal Collection Trust's Voucher scheme offers preferential group rates, based on the volume of business received, and special credit terms to companies bringing visitors to the official residences of The Queen.
Companies not part of the voucher scheme can access reduced admission prices for groups of 15 people or more at all residences, except Clarence House, but no invoicing facility is available. See Opening times & admissions prices page under each residence page for group admission prices.
Royal Collection Trust works with a very limited number of companies on an individual / FIT basis. Companies may register their interest by emailing full details to firstname.lastname@example.org.
