Not sure what this company offers in their "electrical contractors" package of forms but it might be a good place to start. Maybe even call them.
But something that should be verified before trying to apply it. I was talking more about local laws than contract agreements.
Here in MA we are obligated by law to provide at least 1 year warranty and no contract can take that away.
Contracts may extend that, we have done jobs where the company had to agree to a 5 year warranty on some parts of it.
Now of course a contractor might try to ignore warranty work for a job that has a balance but the customer could go to the licensing board about it.
It would really piss me off to be forced to do warranty work on an unpaid job.
And somehow if it doesn't work quite right we have to honor a warranty even though the work hasn't been paid for...?
I can't comment on the legality of it but it does seem pretty unreasonable.
And I don't know how it would work here in the UK or elsewhere. We were acquired by Cooper Controls who were subsequently acquired by the Eaton Corporation. So we were American owned.
The other difference is that we were manufacturing equipment so, for the most part, supplying hardware rather than installing.
Our terms of tender and sale did not change significantly. And were printed with every order acknowledgement and invoice. We had a clause that "title (ownership) would not pass until the goods were paid for in full". That obviously begs the question of how can a "customer" demand warranty on something they didn't own?
Another little gem I got from one of my colleagues many years ago:
"You haven't made a sale until the bill gets paid."
Just thought I'd throw that in 'cos it's pertinent to the topic.
The weather here isn't so I won't comment on it......................
Si hoc legere scis nimium eruditionis habes.
I believe it is not required by law to offer warranty of any kind.
Education is a progressive discovery of our ignorance.
