Hey Lauren, thanks for your feedback and sorry to hear things slipped latterly. I've had a look into the situation and I understand that the landlord instructed us to use his own contractor who visited the property on numerous occasions to reset the boiler which intermittently broke down. Apparently the root of the problem was finally traced to a communal pipe so things were passed over to the property factor to rectify. In retrospect we should have got our own trades people in to make sure the job was completed to our standard so I can only apologise for this. We'll learn not to rely on landlord's preferred contractors at all times if they're not keeping up to our high standards. I wish you the best of luck in your new home :)
