which is a new tenant referencing online application from the people behind http://www.lettingweb.com/

It produces a standard tenant credit check confirming address / checking for county court judgements etc  but also has a nifty free email referencing application that allows you to quickly check previous landlord and current employer details

Quick and cheaper than the competition with instant information coming back.
Also they give you a free check to try it out when you set up your account

If you are an Agent and you call them they may also give you up to 4 free tenant checks if you are likely to be a high volume user

Key benefit apart from being cheaper is that it is faster process to be able to confidently move tenants in.

BE interested in other peoples views as well

Oh and there is a little video demo here
