Evidence guided and outcome driven
We use research and experimentation to help teams prioritise what matters most – reducing risk and accelerating value creation.
Reduce the environmental impact of your web estate
Our website sustainability services provide measurable outcomes through practical improvements to hosting, front-end performance and back-end efficiency.
The value of website sustainability
Lower emissions, improve performance and demonstrate digital responsibility
Website sustainability helps organisations reduce their carbon footprint, align with environmental commitments and drive long-term performance gains.
Reduce digital carbon emissions
Streamlined code, efficient hosting and optimised front ends reduce the energy used every time a user visits your website.
Improve speed and user experience
Sustainability and performance go hand-in-hand – faster websites improve usability, reduce bounce rates and boost accessibility.
Demonstrate environmental responsibility
Showing measurable improvements in digital sustainability helps organisations meet ESG goals and build public trust.
Our sustainability services
Sustainability audits and benchmarking
We’re highly experienced auditing websites using trusted sustainability tools including Website Carbon Calculator and EcoGrader. We assess hosting, code efficiency and front-end performance to establish a baseline and score your website against industry benchmarks.
Our audits identify practical actions that reduce emissions while maintaining UX and accessibility standards.
Low-impact front-end development
We optimise the structure, assets, and delivery of your website’s front-end to reduce energy use and improve loading times. This includes streamlining JavaScript, compressing assets, lazy-loading content, and improving caching strategies.
Built with modern frameworks like Tailwind and Vue.js, our own front-end development delivers lightweight, scalable websites designed for performance and sustainability.
Back-end and CMS efficiency
We evaluate the underlying architecture, database queries and CMS configuration to identify inefficiencies that can increase energy use.
By simplifying code complexity and reducing server processing, we help lower resource demand and improve server responsiveness – especially important for large-scale or high-traffic websites and digital services.
Sustainable hosting guidance
We advise on hosting solutions with a lower carbon footprint, such as providers using renewable energy or carbon offsetting.
We help you understand trade-offs between performance, reliability and sustainability, and make informed decisions that align with your environmental goals.
Monitoring, reporting and improvement
We don’t just measure once – we provide before-and-after benchmarking to show progress and long-term reporting to maintain improvements.
Using transparent scoring matrices and grade tracking, we ensure your digital platform meets sustainability targets and continues to perform efficiently over time.

Built on partnership and trust
We act as a strategic extension of our clients internal teams, collaborating closely and sharing our expertise to build long-term value together.
Following a competitive tendering process as part of our Digital First Transformation project, we appointed DotCentric as our website agency partner. From undertaking user research and analysis, to design and integration with a new CRM and e-commerce platform, DotCentric have provided a first-class service and client experience.
It was an absolute pleasure working with DotCentric. From the initial discussions about our project, to the discovery phase where we fleshed out the requirements, to the implementation phase, the DotCentric team were engaged, proactive, honest and helped us make better decisions based on their knowledge and skillset.
We were really impressed with how DotCentric took the time to fully understand our organisation, our members, what we do and how we work. This ensured that we were all aligned in what we wanted to achieve and worked efficiently together as one team.
It is important for our technology partners to be committed to user-centric practices (user research, prototyping, usability testing) and agile methodology. The DotCentric UX team got to grips with a complex set of needs and drivers and in a short period, they generated the user insight, prototypes and design assets we needed to progress to build.
The team at DotCentric have been integral in helping us to identify opportunities to improve the user experience for our members and have been an invaluable partner in continuing to improve our digital experience.
I have found the knowledge, expertise and guidance offered to Karndean to be of the highest standard. DotCentric have shown an aptitude to fully understand our business and the markets in which we operate.
Approaching DotCentric completely changed our idea of what we needed as they were able to think outside the box and present us with a range of solutions to solve our challenges.
