Website Security for UK MOT Centres and Garages

Why Garages and MOT Centres Need Website Security

Online booking has transformed how customers interact with MOT centres and independent garages. What was once a phone call is now a web form that collects names, addresses, vehicle registration numbers, email addresses, and payment details. That shift creates data responsibilities that many garage owners have not fully considered.

Vehicle registration numbers linked to home addresses and contact details are genuinely useful to criminals — they reveal vehicle type, ownership, and in some cases enable fraudulent vehicle history or finance applications. Combined with appointment scheduling, this data also indicates when a customer's vehicle will be away from their home.

What Garage Websites Collect

**Online booking forms** — Name, contact details, vehicle registration, service type, and preferred appointment slot. This data creates a customer record that links an individual to a specific vehicle at a specific time.

**Payment details for deposits and pre-payments** — Garages that take booking deposits or pre-payments for parts online process payment card data. The obligation to protect this data follows from the moment it is submitted.

**MOT history and service records** — Digital service histories accessible through customer accounts contain detailed records of a vehicle's condition, mileage history, and repair work — information that has value in vehicle fraud.

**Customer accounts** — Repeat customers with accounts hold contact details, vehicle history, and in some cases stored payment methods that require the same protection as any financial data.

Common Security Issues for Garages

**Outdated booking plugins on WordPress sites** — Most garage websites are built on WordPress with a third-party booking plugin. Outdated plugins with publicly known vulnerabilities are targeted by automated scanners that run continuously against the internet.

**No protection on booking confirmation pages** — Booking confirmation pages that display customer and vehicle details in the URL can expose that information to anyone with access to the customer's browser history or who intercepts the link.

**Weak email account security** — The email account that receives booking notifications often has the broadest access to customer data. Without a strong password and two-factor authentication, one phishing email can hand an attacker access to your full booking history.

**No rate limiting on booking forms** — Booking forms without rate limiting can be used to enumerate available appointment slots, harvest vehicle registration and customer associations, or perform automated form abuse.

**Unprotected customer-facing portals** — Online portals that show customers their service history and upcoming appointments require proper authentication. A session management weakness can allow one customer to view another's records.

ICO and UK GDPR

Vehicle registration numbers are personal data where they can be linked to an identifiable individual. Garages that collect this data alongside contact details and home addresses must maintain appropriate security under UK GDPR.

A breach involving vehicle registration numbers, home addresses, and appointment times is a reportable incident under GDPR. The practical harm — enabling vehicle theft or burglary during an appointment — means the ICO is likely to take a serious view of a breach caused by an obvious, preventable vulnerability.

**Practical steps:** Use a reputable hosted booking system rather than a WordPress plugin if possible. Apply updates to your website monthly at minimum. Enable two-factor authentication on your website admin and all email accounts. Run an annual security scan to catch issues before they are exploited.
