The Letting Centre

Hello,

I got in this new house a couple of months ago and as part of the property there is a garden and a shed. Since the house has not enough storage space available I would like to use the shed to put few boxes in. I found the shed in a very poor condition. It is full of rubbish and abandoned building items most of which are broken or too old to be used, the door is broken and does not close and can fall down anytime. Since it cannot be closed few cats use it from time to time... I have asked the landlord to clean it and fix it since it is part of the property and I pay for it but the answer was that it needs too much work and he does not want to do it. I now have decided to fix it anyway and I thought to take the money for repairing out of the rent and informed him of my intention. I also thought I can call the council since the unstable door and the cats can be a safety issue (we have a young boy who soon will start walking).
I would like to ask you if I am right to repair the shed and deduct the money from the rent. What the legal issue would be if the landlord complains?
Am I entitled to repair it at landlord expenses?

Thank you for your advice,

Enrico
