"The Government is carrying out a no-holds-barred review and nothing can be ruled out," said GLA chair Margaret McKinlay. "We are working with Defra and the Department for Business, Innovation & Skills to decide what's best."
On a timescale for the decision, she said: "The Red Tape Challenge website speaks of a three-month horizon, but clearly not everything can be done in that time."
McKinlay had pledged to bring a lighter touch to the GLA's work following her appointment in July. The regulator, based in Nottingham, has around 80 staff.
