In July 2012 Ofcom consulted on a scheme proposed by Royal Mail to alter its delivery obligations to allow larger postal items to be left with neighbours rather than returning them to a Royal Mail office to await collection. The scheme was presented as offering consumers greater choice for receiving mail when not at home, that is if Royal Mail deliver items as per their stated contractual obligations and was said to follow Royal Mail research from a 'delivery to neighbour' trial across six areas of the UK that showed widespread consumer satisfaction. In a statement dated 27 September 2012, Ofcom announced it would approve the scheme after noting that more goods were being purchased over the internet and that Royal Mail's competitors were permitted to leave undelivered items with neighbours. People who do not wish to have parcels left with neighbours, or to receive those of others, can opt out by displaying a free opt-out sticker near their letterbox. Royal Mail remains liable for undeliverable items until they are received by the addressee or returned to sender.
