This does surprise me with Admiral. My wife and I were with them for many years with a multi car policy. Every year the renewal would come through hundreds of pounds more and every year I'd do a quote as a new customer and it would be cheaper than what we payed the previous year. This would then result in a discussion with them on the phone and them then matching the quote. This happened every year without fail.
Looks like they've upped their game perhaps.
I bloody hate searching for car insurance every year, it's a bloody nightmare.
