Did you specify what they could or could not take?
In my estimates I state that the cost incorporates the removal of metals and rubbish. And that this will be either recycled or disposed of with responsibility. I also have my waste carriers licence printed at the header of the estimate.
However recycling materials such as cardboard will be left for the local authority bin collection.
You really should have stated before you got the quote/estimate that these items remain in you possession.
This of course could have affected the price you received.
The boot is on the other foot. Your property must not be removed unless it is in the contract to do so. I is theft and therefore an arrestable offence.
The tradesmen should have sought permission from the owner of those goods, one way would be to state clearly in the contract (i.e. the estimate) .
I remember a few years back a local "Quick Fit" asking if I wanted them to dispose of my o;d exhaust when they fitted a new one. they informed me they had been instructed to ask each customer and of course each customer and of course each customer replied yes please.
Apparently one customer had taken them to court and it ended up in them having to pay up plus various costs so they informed me.
As an electrician I always asked customers if they wanted me to remove rubbish but if was intending to remove anything to be sold as scrap or might be useable for themselves or someone then I would specifically ask about each item.
I once took exception at an opticians, got my new glasses (spectacles) , tried them, the tweaked them etc , all well and good then as I came to leave I could not find my existing glasses, the chap told me they had thrown them in the bin, I told them they had no right to steal or damage my property and to return them immediately, they replied I did not need them them because I now had new ones. That got me angry, I told them I would decide whether or not I wanted to keep them (I did as a back up spare just in case) and insisted that they return them immediately. Ho I was furious, what right had they to do that? None, the cheeky gits, I did let them see me check them for damage when they returned them.
I could not believe they actually did that without prior consent, what an uncivilised rabble they were!
