Would a small claims court be worth it?
Basically I'm a self employed painter and decorator and 2 years ago I booked a client in to decorate their entire house. I stripped all the wallpaper before starting the paint work. After I gave everything a mist coat I used my spray gun to paint a room. They supplied farrow and ball paint. I informed them they needed more paint. They got back to me and insisted they had to cancel the entire job because they could not afford the paint. I offered a cheaper paint alternative in the same colour but they refused. I had them booked in for at least 2 weeks work and I was paid £1300 but lost out on £3090.
Cut to a few weeks ago and I coincidentally bump into the same person after they reached out to me with a different number for a quote on a new property. They told me about how "painters don't use spray guns" and they didn't appreciate how much paint I had used. I got the impression they were looking to get away with just one coat instead of 2. None of these complaints were brought up to me. It's all on text to say they could not afford the paint cost and turned down my offer for a cheaper alternative.
I've looked into this and apparently I do have a case on my side. Even if it's not the full amount.
Has any trades people had this situation before or gone to small claims court before? Is it worth me speaking to someone even just to clarify if it be worth pursuing or not?
