I am currently renting privately and my tenancy is coming to an end in the next couple of months. I received an email from the management company saying that they were delighted to say the landlord would like to offer me another contract but the rent would be £45 per month more and they the agency would be charging me £125 for presumably printing a piece of paper for me to sign. I have told them my salary has not gone up at all so I am not crazy about the increase but haven't given my final decision yet. What can I do?
