You're trusting us with your phone bill. Here is exactly how we protect it.
Last updated: 22/10/2026
Our promise to you
- We use your phone bill and site information only to carry out your audit.
- We never sell, rent or share your information for marketing.
- We never contact the numbers that appear in your call records.
- Your documents are stored encrypted, and only the people working on your audit can see them.
- We delete your bill within 30 days of delivering your report, unless you ask us to keep it.
- We will sign your non-disclosure agreement on request, free of charge.
1. Who we are
2027PSTNswitchoff.co.uk is a trading name of Mergfy. We are the data controller for the information described here. Contact: info@2027pstnswitchoff.co.uk, +44 79 85 135 401.
2. What information we collect
- Contact details: name, job title, business name, email, phone number and site address.
- Phone bills and account information: line numbers, services, account numbers and charges. Bills can also include call records showing numbers called.
- Site information: what equipment is connected to each line, photos taken during a site visit, and notes about alarms, lifts or telecare.
- Website data: basic technical data such as pages visited, collected through cookies (see section 10).
You can hide or remove call detail pages before sending your bill. We only need line numbers and the services on each line.
3. How we use your information
- To carry out your audit and prepare your report, plan and indicative costs
- To communicate with you about your audit and any follow-up work you ask for
- To invoice you and keep financial records
- To send occasional updates about the switch-off, only if you have agreed (you can unsubscribe at any time)
4. Our legal basis
Under UK GDPR we rely on: contract (to deliver the audit you booked); legitimate interests (to run and secure our business, and to reply to enquiries); legal obligation (to keep financial records); and consent (for marketing emails).
5. How we keep it secure
- Bills are uploaded through an encrypted form or sent by email, never by post unless you choose to.
- Files are stored in encrypted business cloud storage protected by multi-factor authentication.
- Access is limited to the people working on your audit, all of whom are bound by confidentiality.
- We do not keep your documents on personal devices or removable media.
6. Software and AI tools
We use secure business software to run our audits, which may include AI-assisted analysis tools. We only use services whose terms prevent your information from being used to train their models, and we never paste your information into public or free tools, e.g. email provider, cloud storage, analysis software.
7. Who we share it with
We never sell your information. We share it only:
- with the service providers listed in section 6, who process it on our instructions under contract;
- with your phone provider, alarm company, lift maintainer or other suppliers only when you ask us to, for example as part of a managed migration;
- where the law requires it.
8. How long we keep it
| Information | How long |
|---|---|
| Phone bills, call records and site photos | Deleted within 30 days of delivering your report |
| Your audit report and plan | 12 months, so we can answer follow-up questions, unless you ask us to delete it sooner |
| Invoices and payment records | 6 years, as required by HMRC |
| Enquiries that don't become bookings | 12 months |
9. Where your information is stored
We store information in the UK or the European Economic Area where possible. If a provider processes data elsewhere, we make sure appropriate safeguards are in place, such as the UK International Data Transfer Agreement.
10. Cookies
Our website uses essential cookies to work and, only with your consent, analytics cookies to understand how it is used. You can change your choice at any time through the cookie banner.
11. Your rights
You can ask us to access, correct or delete your information, restrict or object to how we use it, or move it to another provider. You can withdraw consent to marketing at any time. Email info@2027pstnswitchoff.co.uk and we will respond within one month.
12. Complaints
