As per standard.
As STANDARD You have the right to cancel any work agreed either verbal or in written form within the said cooling off period which is 14 days of the agreement taking place of you receiving it in written form.
You ALSO have the right to waiver the cooling off period if you want the work doing straight away or within the 14 day cooling off period. OR If the service is provided in full within 14 days The right to cancel can be lost during the cancellation period if the service is provided in full before the 14 days elapses.
Where a service has been started within the cancellation period at the express request of the consumer, but has not been completed, the consumer still has the right to cancel.
However, the consumer will have to pay for the service used during the time up to when he informed you of his decision to cancel. What he should pay will be in proportion to what has been supplied in comparison with the full contract price.
The amount is to be calculated either:
•on the basis of the total price ...or
•if the total price is excessive, based upon the market price of what has been supplied, calculated by comparing the prices for similar services from other traders.
