Bank branches the size of garden sheds, staffed with baristas but with no actual tellers, could be the future of banking.

A retail finance expert has told news.com.au that Britain, where the new style bank networks are being rolled out, is "ahead of the curve" when it comes to revamping - and closing - branches and the big banks in Australasia will be watching closely.

The UK's Lloyds Bank is to open tiny branches measuring just 14 meters square in smaller towns and suburbs.

The so-called "micro branches" will be stripped of cashiers and have only two staff on hand who will be armed with iPads rather than the key to the cash drawer.

No money will change hands, instead customers will be directed to a wall of ATMs and other auto tellers.

"Think Apple store, as opposed to bank branches," Jakob Pfaudler, Lloyds' chief operating officer for retail told the BBC.

"We have a lot of branches that used to have a lot of footfall, and therefore feel quite empty and intimidating for customers."

Alongside the micro branches, larger banking centres will open in major cities offering a larger range of services.

Some have speculated the move is a way to avoid politically tricky branch closures, of which there have been hundreds across the UK costing tens of thousands of jobs.

The New Zealand Bankers' Association chief executive Karen Scott-Howman said these initiatives wouldn't be unusual in New Zealand.

"This kind of initiative would be a commercial decision for individual banks.

"While we're not aware of any particular plans here, banks are always looking at innovative ways to enhance customer experience.

"Innovation in banking is largely driven by changes in customer preferences, and competition both inside and outside the banking sector."

According to the Australian Prudential Regulation Authority, banks, building society and credit union branch numbers fell by 315 to 5904 in the year to June 2016.

"The UK is ahead of the curve with branches because there's a lot more competition than in Australia so there's a bigger drive to increase revenue and decrease costs," Professor Steve Worthington, an expert in retail financial services at Swinburne Business School, told news.com.au.

"Everyone is trying to get more value out of their real estate - their branches - and their employment costs.

"Australian banks will be looking closely at this hub and spoke branch idea which could see you having a video conversation from a micro branch with someone in a regional banking centre," Prof Worthington said.

Other new banking initiatives in the UK include Virgin Money, which has opened lounges serving free coffee - but solely to account holders.

Customers will be directed to a wall of ATMs and other auto tellers at bank branches of the future.

While no Australian banks told news.com.au they were going to imminently introduce micro branches, it's no doubt traditional counters and tellers are a thing of the past.
On Wednesday, NAB launched a new concept branch in Sydney called "NAB on George". It includes an "explore zone" for digital products and space for video conferences, seminars and events.

Executive General Manager of NAB Retail, Bob Melrose, said it was the blueprint for future branches.

"The way customers interact with us in five years' time will very likely be different to how they do today, as customers continue to move away from traditional transaction-based interactions like cash withdrawals and cheque deposits in branch."

Westpac is rolling out branches where glass screens are ditched in favour of open plan layouts.

Commonwealth Bank has also cleared away the glass in 88 branches where staff are now encouraged to have "conversations" with customers.

"We are bringing our customer service people out from behind the counter ... where they can provide a greater level of customer service from a more comfortable position," a spokeswoman told news.com.au. "There will be fewer transactions but more conversations."

A 2016 report by Pricewaterhouse Coopers said branches were "possibly the most under-utilised asset banks have."

Billions had been spent on revamps to make them more appealing, it noted, with many now called "stores" rather than branches.

"The vision was some sort of cross between Starbucks and an Apple store. Yet for the past two decades branches in almost all markets have consistently lost share to alternative channels," the report said.

Don't be surprised if your grand old banking hall gets a whole lot more teeny tiny in the years to come.
