Legal Question in Business Law in United Kingdom

Re: Clients and companies

A contractual term restricting an employee's activities after termination is void for being in restraint of trade and contrary to public policy unless the employer can show that it has a legitimate proprietary interest that it is appropriate to protect and that

the extent of protection sought is no more than is reasonable having regard to the interests of the parties and the public interest.

There is no guarantee for an Employer that any restrictive covenant will be enforceable and there are no general guidelines which can be specified as to what would be considered reasonable, for example in terms of time or geography. Each clause must be considered in each case by reference to the business needs of the employer imposing the restriction.

Therefore you need to get advice on the enforceability of your specific clause
