Martin Lewis: Saver builds up £4,000 & buys first home through bank switching - could you?

David concluded by breaking down how he kept on top of this: "When I started I did have a spreadsheet that listed all of the standing orders I had set up, quite a bit of effort involved upfront.

"I would estimate I've made around £1,600 pounds so far and that doesn't include some of the referrals I've made from referring some of my friends and family to do exactly the same thing.

"It doesn't even include the ongoing interest, so if I just left things as they were kept with my old faithful account, I've made £4,000 more.

"I was able to put down the deposit on my first house, and there's no way I would have been able to do that without the bank switching."
