It's now that much quicker for Brits to pay for official services online -- if you use the right services. The UK government now supports Apple Pay and Google Pay for a handful of online services as part of a trial. Right now, it's primarily useful for travel. You can use your mobile device to quickly pay for Global Entry (fast-tracking entry to the US), the Registered Traveller Service (for frequent non-EU visitors to the UK), the Electronic Visa Waiver Service (for some Middle Eastern visitors to the UK). It'll also work for "basic" DBS checks for work.
