Over the many years I had dealings with them, they failed to provide the level of service which you would expect. I was mis-sold home insurance by them (when I say mis-sold, I paid for it but they had never taken out a policy despite numerous requests from them).
A broken window (broken 5 months prior to me moving in) took a further 9 months for them to fix. I went 6 months with light fittings hanging from the ceiling, 4 years with a mouldy bathroom because they refused to acknowledge a problem with the building. Every 5 months I would be contacted by someone, and then when I tried to call them back they would have left. I have a back catalogue of approximately 40 complaint emails I have sent over the years. My only regret is that my landlord was unable to deal with me directly.
Steer clear. Avoid at all costs.
