Quardlyn Security Centre

Last updated: 25 July 2026

Property searches should feel exciting, not risky. This Security Centre explains how to recognise scams, protect accounts and payments, verify advertisers and report concerns.

If you suspect a scam

1. Stop. Do not pay a deposit, holding fee, reservation fee or viewing fee until the person and property are independently verified.
2. Do not share documents such as passports, driving licences or bank statements with an unverified person.
3. Contact your bank immediately using the number on your card or banking app if money or bank details may be at risk.
4. Preserve evidence: keep URLs, property references, messages, email headers, telephone numbers and payment instructions.
5. Report the listing through Quardlyn or email security@quardlyn.co.uk.

Common warning signs

• A price far below comparable property without a credible explanation.
• Pressure to pay before viewing or to move communication away from normal channels.
• A supposed landlord or agent who cannot meet, claims to be overseas, or refuses independent checks.
• Requests for cryptocurrency, gift cards, cash, unusual transfers or payment to a different name.
• Last-minute changes to solicitor, agent or bank details.
• Requests for passwords, one-time codes, full card details or remote access to your device.

Verify an agent or professional

Check the business name, address and telephone number independently rather than relying only on a message. Confirm any applicable redress scheme, Client Money Protection membership and professional registration. For financial services use the FCA Firm Checker and Warning List. Quardlyn verification or publication is not a substitute for your own checks.

Rental safety

• View the property in person or through a trusted representative.
• Confirm the landlord or agent’s identity and authority.
• Read written holding-deposit and tenancy terms before paying.
• Use traceable payment methods and obtain receipts.
• Check that a tenancy deposit is protected within the legally required period where the rules apply.

Buying and payment-diversion fraud

• Use an appropriately regulated conveyancer and verify their identity.
• Confirm bank details by telephone using a number obtained independently.
• Treat any emailed change of bank details as high risk.
• Do not allow urgency or secrecy to override verification.

Protect your Quardlyn account

• Use a unique password and protect your email account with multi-factor authentication.
• Never share passwords, reset links, API keys, OAuth codes or one-time codes.
• Review connected CRM/developer access and revoke anything no longer required.
• Keep devices, browsers and apps updated and sign out on shared devices.

Agent, CRM and developer security

Use separate credentials for each integration, minimum necessary permissions, HTTPS endpoints and verified webhook signatures. Do not place secrets in public repositories, browser code, listing descriptions or support messages. Monitor import, API and audit reports and revoke compromised credentials immediately.

Payments

Quardlyn uses Stripe for supported card and Direct Debit flows. Check that payment pages use the expected secure Stripe or Quardlyn domain. Quardlyn staff will never ask for a password, complete card number, bank login or one-time banking code by email or telephone.

Official UK reporting

• Report Fraud or 0300 123 2040.
• Forward suspicious emails to report@phishing.gov.uk.
• Forward suspicious text messages to 7726.
• Use HM Land Registry guidance and Property Alert for ownership concerns.
• Use the FCA Firm Checker for regulated financial firms.

Report to Quardlyn

Send the property URL/reference, screenshots, contact details used by the suspected fraudster and a description of what happened. Do not email passwords, full payment-card details or unnecessary identity documents. We may preserve relevant logs, restrict accounts or listings and cooperate with affected providers and lawful authorities.
