In a letter from chief executive Brigid Simmonds she thanked the chancellor for his decision to scrap the beer duty escalator and cut beer duty.
She said: “Despite this welcome boost, however, the pub sector remains relatively fragile and we are hoping for further measures to underpin growth and incentivise investment.
“With this vital support for small businesses due to expire in April 2014 we urge you to extend this relief going forward. The potential for a significant increase in costs on our smallest outlets is most unwelcome.”
The BBPA predicted that the cost of not extending the SBRR would be £27m which would “undermine” the support given to pubs in the last budget.
Simmonds also added that to reinforce his position as the most “pro-pub chancellor in living memory” the industry would ask that he consider a freeze on beer duty.
