Thanks for your replies. I have spoken to the landlord and he said the same as you, unless it is in the tenancy agreement don't pay it.

As a newby not sure if this is the right place to post this but here goes. I am about to move out of my rented flat and I have to have a property inspection. Not a problem with that except that the lettings agent wants to charge me £35 for the inspection! There is nothing in his T&Cs about a charge for this, but as he is holding a £500 deposit, if he decides to take it out of that there isn't much I can do about it. Does anyone know if he can legally just take this money without my consent.
