I remember a firm called "Toys are us" and they refused to replace faulty goods, so we never bought anything else from them, there policy was clearly flawed, as they no longer exist.
But with a toy we return to buy more, but with a house we don't tend to say last house was a Laing Homes house and they gave us good service so we will buy another Laing Homes house now this one has worn out.
We are more interested in location than who built it, but when I worked for an electrical firm who did work for a builder, if the builder said I have a problem with the electrics with this house, we sprang into action, as a builder gives one repeat work, which a home owner is unlikely to do.
But there are also the disputes between builder and electrician, I know we did have a builder who was a bad payer and he was often on stop, we had a limit on his account and once he hit that limit we would do no more work, if he rang it was let me check, no sorry your account has still not been paid, and it did not really matter what he needed done.
In theory he should have found some one else to do the work if we refused, it was a time and materials account so not paid by the job, so if there was a faulty item we still charged him to replace it, even if he did not charge the customer. He selected what he wanted to be used, so if he selected poor quality it was down to him.
So when we had a wet room installed in my mothers house, and the builder went to the wall, one we did not have contact details of the electrician, and two he was unlikely to come and do repairs for work he had not been paid for and was unlikely to get paid for.
As to 6 years, this would mean if work has been done just before you retire you could be asked to come and fix it at 72 years old, this does seem unreasonable, I even at 70 am not as agile as when I retired and would not now want to climb ladders. I would say most sole traders would likely return 6 months latter, but 6 years!
There is also the legal problem, when my son decided to cease sole trading and go cards in, he had to sign to say he would not continue to trade, otherwise he could have been using the new firm to find him jobs. He was allowed to complete work under way, and it was agreed there was a time limit, can't remember how long, but know I finished off some jobs for him as he could not do them his self.
In the same way as I completed a job, so he could have employed some one else to complete a job, as could anyone who has retired, but would need to be within the time when he can claim tax back, as it would need to be included in his tax returns.
We do have good will. But if the lights failed next door I would try and fix them for her even when I have never worked on her house, and once a firm or person has stopped trading then good will not help them.
So it comes down to insurance, and I know my son had insurance, so if some thing had gone drastically wrong after he had finished trading then I suspect he could have still claimed on insurance? I have not a clue really how that works, I know with cars we had a knock for knock system and the insurance companies agreed with each other who would pay for what.
But I have never seen on a bill who the insurance company is, so if my friend Stephen had unfinished or faulty work in progress when he died, I am sure the insurance would cover, but how one would know who to claim from not sure. And 6 years latter don't think his widow would know who he had insured with.
