It even has tick boxes for whether the builder can plug his mixer into the electricity supply free of charge, and use the indoor loo, the phone or the water. The programme is simple and so is what happens if the builder needs an extension of time. It applies when the builder has to spend extra time on the works because of changes, or cannot finish on time for reasons beyond its control, including delay caused by the customer.

Responsibility for security of the house and insurance details are also covered by tick boxes. The contract's disputes machinery is innovative, indeed brilliant.

It has to be optional because no one can force the builder or homeowner into adjudication under the Construction Act - domestic contracts are outside the scope of the act.
