The company offers gas and electricity supply services with an emphasis on competitive pricing, transparency, and customer convenience through online tools such as savings calculators and contract management. The website reflects a well-structured digital presence with clear navigation and professional branding consistent with a large energy sector player.

Security Posture Analysis
Comprehensive Security Assessment
The website enforces HTTPS and uses cookie consent management to comply with privacy regulations. Form inputs have client-side validation to reduce input errors and potential injection risks. However, the absence of visible security headers such as Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain web attacks. There is no publicly available security policy or incident response contact information, which limits transparency and preparedness perception. No vulnerability disclosures or security.txt files were found. Overall, the security posture is moderate with good baseline protections but lacking in advanced security communication and headers.
Strategic Recommendations
Priority Actions for Security Improvement
Implement and publish a comprehensive security policy and incident response plan on the website.
