There's a Barclay's advert on the radio at the moment, which proclaims to help everyone with the cost of living rise, by allowing them to switch mortgage rates 180 days before their current mortgage expires. Great you might think! However, the advert then says, that your new rate will apply as soon as your old rate expires. So, in reality, all they are doing is letting you choose your new rate 6 months in advance, it won't actually apply the new rate until the date your old mortgage expires. And who knows what happens if you choose a new rate in advance and then base rate goes down. The advert is really pitched as though they are doing you a massive favour, but they're not, are they?
