I want the landlord to Agree to show me proof of receipts that work has been carried out and can you email me a copy of proof of receipts when work has been carried out. Three days later , surprise surprise no email reply agreeing to my fair terms. Which says to me, the owner won’t spend any money on handyman unless he is forced to by a legal body eg Fair trading.
Or maybe they’re just responding (by not responding) to someone who is basically saying “I don’t trust you to do what you promised …”
Maybe dial it down a little and see what happens. If nothing, then maybe Fair Trading, or maybe a civilised chat with the landlord about their tenants … Noise is 50 percent behaviour … if everyone is annoyed at you, receipts aren’t going to make any difference.
