What the Builder Should Expect
Many disputes arise due to mixed messages from the client, so remember that you have a responsibility to ensure the work goes smoothly as well.
Throughout the process, the best way to avoid problems is to maintain a mutually respectful relationship with the builder.
The Supply of Goods and Services Act 1982 requires traders to provide services to a proper standard of workmanship. Furthermore, if a definite completion date or a price has not been fixed then the work must be completed within a reasonable time and for a reasonable charge.
