However, Camra has called for the government to tighten planning legislation, making it harder for developers to convert pubs and obliging them to apply to local authorities for permission.
The campaign group said an average of two pubs a week had been turned into supermarkets since 2012.
The move has already been backed by 44 MPs in the UK who have signed an early day motion in Parliament supporting the campaign.
Tom Stainer, from Camra, said pubs were being left vulnerable by "gaps" in the planning legislation.
"Pubs are increasingly being targeted by those wishing to take advantage of the absence of proper planning control," he said.
