4 years ago tenant moved into my flat. I provided a new cooker for her. It's now not working. On closer inspection, she has used it a lot (fair!) but never cleaned it (disappointing), damage from her treatment of it is what has damaged it.
She needs another one.
But I don't really think this is reasonable wear and tear - more neglect and abuse.
Reasonable inspections and checks have been carried out regularly, compulsive gas safety checks have been done.
If she moved out tomorrow I could deduct at least part of the replacement cost from her deposit, but as she's staying, what would be a fair way forward?
