Our packages Get started
We're a marketing agency based in Thanet, Kent. We work with businesses across the county and beyond, from local tradespeople and professional services to growing e-commerce brands.
When you work with Codex, you get more than a finished website. You get a team that takes the time to understand your business, your customers and what you actually need the site to do. Every project is built around your goals, not a generic template.
Here's what every Codex website includes as standard:
We're straightforward to work with, transparent about what we're doing and focused on delivering something that actually performs for your business.
Design is important, but it's only part of the picture. A website that looks great but is difficult to navigate, slow to load or unclear about what you offer won't hold a visitor's attention for long.
When someone lands on your site, whether through Google, a referral or a social media post, they're making quick judgements. A well-structured website builds trust, answers the right questions and makes it easy for people to take the next step if they're ready to.
We think about the full picture when building a site: how it looks, how it performs, how it reads and how it fits into the wider way people find and choose a business. Take a look at some of our recent work to get a feel for what that looks like in practice.
See our case studiesWe take the time to understand your business before we start designing. That means getting to know your audience, your goals and how your website fits into the bigger picture for you.
The websites we build are well-crafted, properly optimised and designed to represent you well online, whether someone is visiting for the first time or coming back as a regular customer.
Before anything is designed, we take the time to understand your business, your audience and what you want the website to achieve. That research shapes every decision, from the structure of the pages to the way the content is written, so the end result actually reflects who you are.
Every website we build is set up correctly for search engines from day one. That means proper heading structures, fast load speeds, mobile-first design, clean code and content built around how people actually search for your services. It's far easier to get this right during the build than to fix it afterwards.
We care about how your website looks, but every design decision is backed by a reason. Page layouts, content structure and navigation are all considered with the visitor experience in mind, making it easy for people to find what they need and understand what you offer.
Once your site is live, we're still on hand. Every package includes monthly update time, so if something needs changing or adding, you just get in touch and we'll take care of it. No technical knowledge needed on your end.
Every business is different. Some need a clean, simple online presence to establish credibility. Others need a full multi-page website built to rank and convert. Our packages are designed to scale with your needs, and every one includes ongoing monthly support as standard.
In December 2025, we attended the Small Business Awards UK ceremony and came away with two national recognitions we're really proud of.
Codex was ranked 7th best web design business in the UK, placing us in the top 10 out of hundreds of agencies across the country. We were also recognised in the top 50 best digital marketing businesses in the UK.
It was a brilliant evening and a great reflection of the work our team puts in every day. We don't shout about awards often, but this one felt worth sharing.
We've worked with businesses across Kent and beyond, from local tradespeople and independent retailers to professional services and hospitality brands. Each project is different, and our portfolio reflects that variety. Have a browse and get a feel for the kind of work we do.

It's one thing to build a good-looking website. It's another for that website to make a real difference to a business. Here are a few examples of projects where our clients have seen tangible results since going live.
By combining thoughtful design with solid SEO foundations and good performance, the sites we build tend to rank well and attract people who are already looking for what our clients offer.
"The website paid for itself quicker than we expected."
The cost of a website varies depending on the number of pages, the complexity of the design and the features required. A simple one-page website will be considerably less than a large multi-page site or an e-commerce platform.
At Codex, we offer a range of packages to suit different business sizes and budgets. Get in touch and we'll talk through what's right for you.
Timelines depend on the size and complexity of the project. A smaller website can typically be designed, built and launched within a few weeks. Larger or more complex projects take longer, but we'll always give you a clear timeline before work begins so you know what to expect.
Yes. Every website we build includes on-page SEO as standard. This includes correct heading structures, page speed optimisation, mobile-first design, meta titles, descriptions and clean code. We also offer ongoing SEO services if you want to continue growing your visibility after launch.
Yes. All of our packages include monthly update time and ongoing support. We keep your website secure, up to date and fully functional so you can focus on running your business.
Absolutely. If your current website is outdated, slow or no longer reflects where your business is, we can redesign and rebuild it. We'll look at what's working, what isn't and what would make it better, then take it from there.
Yes. We build e-commerce websites for businesses wanting to sell products or services online. Whether you need something straightforward or a more fully featured platform, we'll build something that's easy to manage, fast to load and straightforward for your customers to use.
Every website we build is fully responsive, meaning it looks and works exactly as it should whether someone is browsing on a phone, tablet, laptop or desktop. In a world where the majority of web traffic comes from mobile devices, this isn't optional. It's essential.
A responsive website also gives you one place to manage your content, with updates reflecting consistently across every device. And because search engines prioritise mobile-friendly, fast-loading sites, getting this right from the start gives you an edge in search rankings too.
