Your website is costing you more
than you think.

Slow pages lose customers. Bloated code wastes energy. Bad speed kills your search ranking.

Your agency made it look good.
We make it work.

Most agencies make things look good. We make them work. Faster load times, lower costs, better rankings, and real proof of your green claims.

Audit

We find what's slowing your site down. We spot what wastes energy and what hurts your search ranking. No guesswork.

Fix

We rebuild the parts that matter — speed, access for all users, and compliance. Clean, lean code that most agencies can't or won't write.

Prove

We give you the numbers — speed scores, carbon savings, compliance reports. Show your stakeholders real, measured impact.

Accessibility isn't a feature.
It's a requirement.

If your website can't be used by everyone, it's broken. B Corps must meet JEDI goals — but access isn't just a checkbox. It's the baseline. Every person, no matter their ability, should be able to use your site. We audit and fix to WCAG 2.2 AAA, the highest standard.

WCAG 2.2 AAA Compliance

We don't stop at AA. We test every page for colour contrast, keyboard use, screen reader support, reading ease, and touch targets.

B Corp JEDI2 Audits

B Corp's JEDI Standards V2.2 need proof that your website is open to all. Our JEDI2 audit gives you that proof — a score, a report, and a clear path to full compliance.

WSG Compliance

The W3C Web Sustainability Guidelines (WSG) set the new standard. We check all 93 rules and give you a clear path to compliance — before your rivals get there.

The P.E.E.R. Framework™

Every project we deliver meets four strict criteria. This is what sets true sustainable web work apart from basic web design.

P

Performance

Ultra-fast websites that turn visitors into customers. Speed shows quality to both users and search engines.

The Digital Sustainability Consultancy

OYNK is a digital sustainability consultancy. We cut Digital Waste. We work with purpose-led brands, B Corps, and forward-thinking groups that need their websites to match their Net Zero goals.

We solve three key problems: lost revenue from slow sites, brand risk from wasteful digital habits, and wasted time from messy tech.

Our message is simple: we make your digital world cleaner, faster, lighter, and better for business.

"OYNK has engaged with the college to inform on sustainability within digital services as part of our ongoing employer skills forums and sustainability agenda. Their objective on digital sustainability awareness has had a positive impact on all staff and their insights have helped us inform colleagues across the college. More importantly, the impact on our students and how we embed this into the teaching and learning to enable them to be prepared for careers of the future in the digital sector. We look forward to working with Ash further on his initiative to work towards Northamptonshire improving website CO2 emissions."

Frequently Asked Questions

Everything you need to know about working with OYNK and how we build greener websites.

What is Digital Waste?
Digital Waste is the carbon, energy, and wasted effort caused by poorly built websites. Think bloated code, huge images, and needless server calls. They waste energy and hurt both user experience and the planet.
What is the P.E.E.R. Framework?
P.E.E.R. stands for Performance, Experience, Emissions, and Ranking. It's how we audit and improve websites across these four areas. The goal: your site delivers business results and stays kind to the planet.
How long does a P.E.E.R. Audit take?
A full P.E.E.R. Audit takes 2-3 weeks, depending on the size of your site. This covers deep analysis, team chats, and a clear action plan with ranked next steps.
Do you work with organisations outside the UK?
Yes, we work with purpose-led groups around the world. We're remote-first, so we team up with clients across time zones. This also keeps our own carbon low by cutting travel.
What industries do you specialise in?
We mainly work with B Corps, purpose-led brands, charities, and groups chasing Net Zero. Our clients come from green fashion, clean energy, ethical finance, and social enterprise.
Can you help with AI sustainability?
Yes. Our Sustainable AI service helps you use AI the right way. We focus on picking low-energy models, lean set-up, and honest carbon tracking for your AI work.
