Even worse, it is likely to take you 10-11 months to spend £20k, I imagine. This gives you minimal flexibility in when you trigger your voucher. If you get the Premium Plus card, on a £2k / month spend rate, you can spend £9,900 relatively quickly and then w..a...i...t until the most appropriate time for triggering the voucher, based on when you want to use it.
