I have a unit in a shopping arcade. The landlord got an electrician in to do some refurbishment work, and the electrician cut a wire which set off my shop alarm. The police came out and my alarm company charged me nearly £150 to repair the system. The landlord says I should take the matter up with the electricians, but they refuse to pay the bill.
You may be able to deduct the amount you had to pay the alarm company from your rent. You should write to your landlord telling them what you propose, and suggest they recover the money from their contractors. You could bring a small claim in court against both the landlord and the electricians and let them sort out between themselves who’s going to foot the bill.
