TPSClear
TPSClear solves a specific UK problem: calling a number on the Telephone Preference Service (TPS) or Corporate TPS (CTPS) register without consent is a PECR breach, and since 5 February 2026 the ICO can fine up to GBP 17.5 million or 4% of global turnover.
Most teams either screen nothing or upload CSVs to a bureau and wait. TPSClear screens inside the CRM instead. The moment a phone number is added or changed on a HubSpot contact or company, or a Zoho CRM lead, contact or account, the verdict is written back to the record within seconds. Every number is re-screened 27 days after its last check.
The verdict lands on a normal CRM field, so it works in lists, workflows, sequences and reports, with a separate result for each phone field. Voll Studios Ltd, the company behind TPSClear, is licensed by the DMA as a TPS and CTPS list cleaner. Register data is supplied through our licensed data partners.
