UK phone rental - reputable firm?

We are going for a brief visit to the UK in early July. Since our visit will be brief and it is unknown when we will get back to Europe, I think it will be more economical to rent a phone than buy even a cheap one. That being said, I found a company called "Adam phones" that seems to have the sort of rate I am looking for.

Do any of the UK folks know if this is a reputable firm? If not, do you know of one? Thanks very much for any information you can provide.

Oops! Sorry- This is what happens when I compose messages when I am tired. We will be staying in Wokingham and Royal Tunbridge Wells. Both are pretty close to London.

Thanks very much for the information you provided!
