Is Vanguard still the best and cheapest? - New minimum account fee

I’ve just seen that Vanguard is introducing a new minimum account fee for investors whose portfolio is under £32,000. £4 per month (£48 per year) instead of 0.15%. Vanguard was known for being one of the cheapest investment platforms (fees-wise). With these changes are they still the cheapest and/or best? If not, is there any advice for who we should change to?

Edit: I’m signed up with UK Vanguard. Didn’t realise they work a bit differently. Also, I want to specify that it’s the S&S ISA that I do with them (ETFs) - in case this changes your advice.
