We have rented 3 different properties over the past 3 years and Farrell Heyworth is by far the worst letting agent we have had to deal with.
We had to pay £200 for credit checks, references etc before being shown the contract which would have deterred us from taking the property if we had seen it in advance. The property has to be inspected every 3 or 4 months, the tenant must request permission to decorate or make any changes, which was a joke because the wallpaper was hanging off the walls in most of the rooms. There were loads of additions to the contract like getting the house fumigated on leaving because we had 3 gerbils, we were responsible for drainage problems and problems with mildew, all things that existed before we moved in .
After moving in we realised the back door frame was rotten and had to threaten legal action before they got it fixed. We found a British Gas warning sticker on the fuse box stating "Danger do not use", told Farrell Heyworth but they said it was probably just something trivial and the landlord was not under any legal obligation to get the electrics tested.
When we gave notice we were hounded to show people around and told that it was in the contract. (The contract only said we needed to allow access to the agent and viewers not show them around). On quitting the tenancy we agreed that the borders of the front garden needed some work, ie. removing moss and they took 5 weeks to get a quote of £230. The garden was only around 4m square with half metre borders.
