Regular small Bitcoin saving mechanism?

[skovbitcoin]

So I've been wanting to get into Bitcoin for a while now. However, I am entirely useless at actually commiting any money to it. I was thinking about saving a small amount of £ per day/week/month, on a regular basis into my wallet of Bitcoin. Thing is, I've had a look and can't find a mechanism by which I could do this easily. Can you guys help point me in the direction of some kind of way of regular saving, from my debit account or similar? I'm in the UK.

Thanks

Mark
