Not according to this FAQ from the TPS site:
- Do I need to renew my subscription with the TPS? If you have registered a residential number or a number belonging to a sole trader or (except in Scotland) partnership, you do not need to renew. However, if you have registered a number on to the Corporate TPS belonging to a Limited company, Plc or other large organisation, you are required to renew annually. In this case TPS will send you an e-mail each year to notify you of this. Failure to renew will result in your number(s) being removed from the CTPS data file. Please be aware that if you change your telephone package, obtained broadband or change telephone line service provider for example, we may receive notice from your current/old line service provider that your line has been made inactive. In this case your number would be removed from the file as the service is only intended for live numbers.
