Can’t recall where I saw it in the past (maybe even on HN - I know a bunch of the digital team hang around here) but I read something about how it was also important to make it function well on low powered mobile devices with poor internet because a lot of people that need the service aren’t as fortunate as many of us.

Honestly, I love the work the Uk team has done on the digital services. I find them a real pleasure to use. Very clear, consistent and functional. There are a lot of corners they’re yet to get to, but the areas that have been sorted out are great.
