Before agreeing or starting work in a domestic British house, a tradesman should explain the following details to the householder, which are legally binding to both parties in UK law:
Contracts and Agreements
It is important to have a written agreement between the tradesman and the householder that covers the work and any other relevant information.
The agreement should set out exactly what you intend to do and not be vague, it should set out the approximate time frame. Any services that the customer is liable for such as skips, other trades that might be needed, who is supplying materials, essentially what the customer expects.
The agreement should be signed by both parties and a copy kept by each party for reference before you start any work,
Uunder UK law if you are the first contractor to discuss the job you will be considered to be the Principal Contractor and you will be liable for any other trades involved with the project regardless of who introduced them , instructed them or who paid them!!!
For example do not state in the agreement that you are to just "fit a kitchen" ....state that you are to fit the kitchen wall and base units, hang d=doors, fit drawers, fit worktops install sink and taps, if a plumber has to fit any gas appliances, make it clear in the agreement that this is outside the scope if the agreement.
Be advised that JCT Contracts do not stand in Welsh courts.
Get familiar with your liabilities under the CDM 2015.
Nature of the work:
The tradesman should clearly explain the type of work they will be carrying out, including any necessary repairs, replacements or installations.
Cost of the work:
The tradesman should provide an estimate of the cost of the work, including materials, labor and any additional expenses. The householder should be informed if the final cost may differ from the estimate due to unforeseen circumstances.
Payment terms:
The tradesman should explain the payment terms, including any deposits, interim payments, and the final payment.
Timeline:
The tradesman should provide an estimated start and completion date for the work.
Warranty:
The tradesman should explain any warranties that may be available for the work or materials used.
Insurance:
The tradesman should confirm that they have the necessary insurance coverage, such as public liability insurance, to protect both the householder and the tradesman in case of any accidents or damage during the work.
Children and Pets.
Clarify that you are there to carry out your trade and that children and pets should not interfere with your work and explain the relevant safety issues if need be such as sharp tools, floorboards being lifted, electric drills, impact drivers, sharp nails or screws.
It is not unreasonable to suggest that pets are and children are relocated whilst work is being done.
The tradesman should inform the householder of any health and safety measures that need to be taken during the work, including any necessary evacuations or temporary arrangements.
