I have had a year tenancy in one of their managed properties and have never had a worse experience with any company. There have been so many problems with the property that we ended up writing to the landlord to ask them if they knew.
It turned out they didn't.
When we could get them to do work on the flat (which wasn't often) they hired cowboys to do it and then charged the landlord a fortune.
For the entire tenancy there was a leak in the shower room which ruined the walls, carpet and various other things and only got fixed when the landlord got involved.
We were without hot water on a number of occasions and had to move out for a time while it was fixed. The guy who "fixed" it hardwired the heating to the mains so the emmersion heater was running 24/7 and couldn't be switched off. This resulted in a £1000 electricity bill which we were not expecting.
It got to the point when they wouldn't even talk to me on the phone and I had to go and camp out in their offices.
Total disaster, whatever you do don't sign up with them!
What agent could do to change your mind?
No - they were truly awful
