Yes you can get a contractor in to do the work if the landlord or agent have refused or not bothered to do anything. Make sure you have a paper trail though.

If the agent is managing the property on behalf of the landlord, its the agent who becomes responsible for the overseeing of work, so you don't need to try and hunt down the landlord, you just correspond with the letting agent and its the letting agent you'd invoice if you did end up having to get your own contractors in.
