£1.25 (£1.47 inc VAT) at Gloucester, down 16ppl from last month.
The lag is normally down to volume sold. Small operators will still be selling the stock they bought 3 months ago at the peak. The Pound going pear-shaped against the Dollar isn't helping matters. If we were still up around the $2=£1 mark, it would probably be close to the forecourt price. Duty hasn't changed, it's still around 30ppl.
