I have done much bigger jobs than this I call this ONE OF THOSE JOBS !! Started sh!7 got worse then ended sh!7 I've started my epic letter
PJ, it is sad that what happened happened. But sheet happens. We all wish that this matter will be resolved and hope you will at least get money for your materials that you used on the job, and a bit for your labour.
But before you go head in, I will just like you to please look at the bigger picture.
If you start writing to the customer now and making them aware you are going to take legal action etc, my gut feelings tells me that this may just spur them on and make them even more angry? Try and put yourself in their position (someone has already pointed this to you in an earlier post). You decided that their boiler needed changing, removed old boiler, fitted new one and radiators on one floor work but not on the other? You have a pin hole leak on a 28mm pipework? You fit the flue then tell them it is wrongly fitted and has to be altered? You switch off the new boiler (and leave them I presume over the weekend with no heating or hot water)? Anyone who has a bit of an idea will try to turn on the boiler to at least have a shower. Yes, you might have told them not to touch it, but people always do.
Just let's say they left the boiler on all weekend and products of combustion etc got in and someone got ill or worse. What do you think the outcome would have been?
We all agree the customer is trying to get away with not paying you and also wants to keep some of your pipework, flashings, etc which is rather strange. How come they think it is done right?
Personally, I will suggest you put a line under it. Consider it a very bad experience and move on. The more you dwell on this, the more you get distracted from other work you should be doing and the more you get bugged down with it.
So you will prefer to go and remove your boiler, but they may also be of the opinion that if they let you access to the property, you may decide to damage the pipework etc that you had fitted. Especially considering they have informed you they intend to keep it and not pay for it?
By all means, send them your letter(s), but be polite and apologetic. Tell them you admit things did not go to plan but things of this nature do happen once in a while (remember all those millions spent on an NHS computer system that eventually got scrapped???). Tell them you are more than happy to attend and complete the job at no extra cost to them. Inform them that you will gladly reduce your labour charge due to the inconvenience they have ''suffered''. Finish by letting them know that if they have decided not to let you complete the installation, then you will be happy to come and remove your materials etc. Present yourself in a genuine and caring manner.
I am not so sure that takin this matter to court or threatening them with legal action will achieve anything. JUST MY VIEW.
Take the loss on the chin, liken it to a bad investment in the stock market or similar, and forget about it.
WISHING YOU ALL THE BEST IN WHAT EVER ACTION YOU CHOOSE TO FOLLOW.
