Why shouldn't I do this myself?

You can, but helloBill saves you time: digging out the current suppliers to your new property, pulling comparison quotes if you want them, and arranging your new services. Anything tricky with a provider during the set-up? helloBill handles the back-and-forth and keeps you posted. So yes, you can do it yourself — or helloBill can do it for you, so you can spend those hours on something you enjoy.
