We have just had a load of work done to our house including some rewiring, light installation, painting and decorating.
Two of the light fittings are not working. Our builder has said that we have paid him for installation but as we have supplied the dimmer switches ourselves, it is not his responsibility to ensure that anything he has installed works.
Is this correct? We are in contact with the supplier of the switches, regardless. But I had assumed that if someone was paid to install something, that they should try to make sure it actually works.
