For financial IT in London specifically, I would always advise people to state you have multiple interviews and roles on the go, and do so, so that if you are made an offer, get it in writing, even though then pretend it is an time limited offer, and then get at least one or two rounds of counter offer. And don't feel bad about doing it. They will squeal a bit, but it is just business at the end of the day. And yes, do job hop from time to time or else your pay will stagnate. A good rule of thumb is to interview every three to six months to establish your market potential and look at the difference on your current role.
