According to the latest BRC/Springboard Footfall Monitor, September's footfall was 0.9% down on a year ago, up on the 1.1% fall in August and in line with the three-month average of a 0.9% decline.
Out-of-Town reported the only rise, 0.5% higher than a year ago, while footfall on the high street was down 0.6% on the previous year.
Footfall in shopping centres was 2.6% down on the previous year for September, the deepest decline since October 2013.
All regions and countries with the exception of South East (1.4%), Northern Ireland (0.2%) and Scotland (2.0%) reported declining footfall.
Helen Dickinson, British Retail Consortium Director General, said: "September's footfall figures are a bit of a mixed bag. Out-of-town footfall continues to grow compared to last year which shows that consumers are increasingly confident. Demand for big ticket items continues to be strong with furniture outperforming all other categories."
"The South East also fared well showing growth in footfall for September of 1.4%, which is in contrast to the slight decreases in footfall across the other English regions overall. To look at the figures initially they seem slightly gloomier than they actually are. Despite a dip for the month of 0.9%, largely due to less visits to indoor shopping centres, footfall was up on the 1.1% fall for August which shows that it is going in the right direction.
"As online sales increase overall we can see how shopping is changing and retailers are adapting. The industry is working hard on providing great online shopping experiences for consumers and this too impacts footfall. However, with Christmas fast approaching footfall is only set to increase on the high street, out-of-town and in shopping centres."
