Risk levelMedium

0–100, higher is better. How it is calculated

Gas Tech (Wales) Ltd is a small, specialized energy services company based in the United Kingdom, focusing on central heating solutions including boiler installations, servicing, and maintenance. The company emphasizes its Gas Safe registration and offers grant funding options, positioning itself as a trusted local provider with over 70 years of combined experience. The website is professionally designed with clear navigation and multiple contact channels, including phone, email, and a contact form, supporting customer engagement and lead generation. Technically, the site leverages modern web technologies such as jQuery, Ecwid ecommerce integration, and PWA features, hosted on CDN infrastructure for performance. Security posture is good with HTTPS and CAPTCHA protections, though some security headers are missing. Privacy and cookie policies are present, indicating basic GDPR compliance. However, the domain WHOIS data is unavailable due to a naming rules violation error from Nominet UK, which slightly reduces trust from a domain registration perspective. Overall, the site is functional, professional, and secure, suitable for its business purpose.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company operates in the energy sector, targeting homeowners and businesses in Wales needing heating services. Its business model is service-oriented, offering installations, repairs, and maintenance with financing and grant options. The presence of testimonials and social media links suggests active customer engagement and marketing efforts. The company appears independent with no parent or subsidiary relationships disclosed. The website content and branding are consistent and trustworthy, supporting a positive market position as a local specialist. The use of third-party platforms like Ecwid and ServiceM8 indicates integration with service management and ecommerce tools, enhancing operational efficiency.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA on forms, and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options is a gap that could be addressed to improve protection against common web attacks. No vulnerability disclosures or incident response contacts are published, which is a common gap in small business websites but worth considering for future improvements. The domain WHOIS anomaly is a concern but does not directly impact website security. Overall, the site is secure for typical business operations but could enhance defenses and transparency.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to strengthen web security.
  2. Publish a security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Investigate and resolve the domain WHOIS registration anomaly to improve domain trustworthiness.

Notes

The website is built on a modern tech stack including jQuery 3.7.0, skrollr for animations, Ecwid for ecommerce, and ServiceM8 for customer feedback integration. It uses Google Fonts and is hosted on CDN infrastructure (cdn-website.com and CloudFront) for performance optimization. The site supports PWA features with a service worker registered, enhancing mobile experience and offline capabilities. Performance is moderate with good mobile optimization and basic accessibility. SEO is supported with proper meta tags and Open Graph data. The site uses a CMS platform likely Duda, inferred from runtime scripts and API references. Overall, the technical implementation is solid with room for improvement in security headers and accessibility.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
