We let out a house to a new tenant. When they moved in there was a brand new kitchen and all new white goods: washing machine, dishwasher, tumble dryer, cooker, hob and a large fridge freezer. We had gas and electric checks and certificates issued and painted all rooms and cleaned all carpets before they moved in. Tenant saw our cleaner and asked to borrow it to clean the carpets herself. I agreed so they were cleaned twice. After a few weeks she text to say the bath was blocked and water did not run away. We went up and saw water slow to flow away so called plumber and he plunged it and said the bath was blocked with lots of long black hair. The tenant has long black hair. She also said there is a smell in one of the bedrooms. We can smell nothing. We asked plumber of he could smell anything but he said no he couldn't either. Two weeks later she text to say shower did not work. We went up but shower was working fine. Two weeks later text again said shower did not work. We went up and ran shower for 20 mins and it was fine. She said fuse flipped down so we got electrician to checkout fuse box and he tested and said it was fine. Three weeks later she text and said boiler was going off so thought it was broken. We went up yet again and as weather warmed up she had thermostat at temperature that meant it went on and off to keep to temperature she had it set at. So nothing wrong with boiler. At the same time she asked to borrow our industrial carpet cleaner again which which we agreed to as she says one of rooms smells. We can still smell nothing. Now she has text me demanding carpet is changed for new laminate flooring. I want to tell her there is nothing wrong with the carpet and so she can't have new laminate flooring as we can only legitimately claim expenses on replacing old/broken items and the carpet is only 3 years old and nothing wrong with it. We have other properties and keep them up to a good standard. AIBU to refuse her laminate? We have already paid for a plumber because she blocked bath with her own hair and an electrician when there was nothing wrong with electrics.
