Every few years, someone declares WordPress dead. Meanwhile, it quietly powers over 40% of all websites, from personal blogs to Fortune 500 companies, government sites to global e-commerce operations.
The reason is simple: WordPress works. It's flexible enough to build almost anything, stable enough to trust with your business, and open enough that you're never locked in to one developer or platform.
But WordPress is only as good as the people building with it. A poorly built WordPress site can be slow, insecure, and frustrating to manage. A well-built one is fast, secure, and a genuine pleasure to use.
We've been building with WordPress since the early days, before Gutenberg, before the REST API, before it even had custom post types. That experience means we know which approaches work long-term and which create problems down the line.
Our WordPress development services are ideal for:
Your existing WordPress site is slow, hard to update, or held together with too many plugins. You need someone to rebuild it properly.
You handle design and client relationships. You need reliable WordPress development to back it up.
Off-the-shelf themes and plugins don't quite fit. You need custom functionality built to your exact specifications.
Changes take forever. Updates break things. You're ready for a developer who actually knows what they're doing.
Honest note: We're not the cheapest option for simple template installations. If you just need a theme installed and configured, there are faster and cheaper routes. We're for when you need it done properly.
Custom themes, not page builders. We develop bespoke themes from scratch. No Elementor, no Divi, no bloat. Your site loads fast because we only include what you actually need.
Clean, maintainable code. We follow WordPress coding standards and best practices. Any competent developer can pick up where we left off, though we hope you'll want to stick with us.
Security from the ground up. We harden every installation: proper file permissions, security headers, limited login attempts, and careful plugin vetting. Your site won't be the low-hanging fruit.
Performance obsessed. Efficient database queries. Proper caching. Optimised assets. Every decision considers speed because slow sites lose visitors and rankings.
Block editor ready. We embrace Gutenberg and build custom blocks that let you update content confidently, without needing us for every small change.
We've been building with WordPress since version 1.x. We've seen every trend, every security scare, and every major evolution of the platform.
We maintain plugins in the WordPress.org repository. We understand WordPress internals, not just how to use it.
Most sites need far fewer plugins than they have. We'll build what you need and choose plugins carefully for the rest.
We build custom blocks that give you the editing experience you actually need, not a confusing wall of options.
Your site lives on our own 365i Hosting platform, optimised specifically for WordPress. No finger-pointing when something needs fixing.
We build sites that will still work properly in five years. No hacks, no shortcuts, no "we'll fix that later."
Need e-commerce? We integrate WooCommerce seamlessly with custom themes, with no awkward mismatches or bolted-on functionality.
Moving from another platform or a mess of a WordPress site? We handle migrations cleanly, preserving what matters.

I would be absolutely lost without Mark at 365i. They have helped me no end - I was (am!) an absolute novice and it was such a relief that I could put all my confidence into Mark and 365i services. They have delivered above and beyond and I would recommend to anyone who either doesn't know where to start, or wants to recreate to make an impact. Thank you Mark and 365i!!
Service beyond fantastic. It's hard to put into words how thorough and in-depth the level of service was, and it ftruly felt as though Mark had a real passion for my business, and was himself thrilled to achieve high speeds! I cannot reccomend enough! Amazing!
If carling did web hosts and support. Simply the best! Thank you so much Mark.
Wow!!!! This guy goes above and beyond for anyone!! Must admit, I never really knew his limits but I can honestly say that without this amazing web page, I would be struggling!! Thankyou so much, I love it!!!
My current domain supplier suddenly went into administration meaning that I was losing the email service I’d used for 25 years. I contacted several hosting providers who wanted to take your money for a new account but couldn’t offer the transfer. However, Mark & the team were extremely helpful in sorting the transfer of my “unusual” domain to their services. I can’t recommend them enough especially after they expended a couple of painful days working behind the scenes & doing everything to facilitate the process. Thank you.
Awesome hosting service, customer support second to none with dedicated UK based team, highly recommend to agency and business owners
Very knowledgable and did a great job - I would definitely use again.
Mark provided superb service - rapid response, careful consideration of my requirements and great website design. Everything was wrapped up really quickly and with superb quality. Highly recommended.
Amazing hosting with great support, always going above and beyond to help and make the clients happy. Recommended.
Just the best I’ve ever used! Our sites run so fast, and they bend over backwards to help when we get in trouble and don’t know what to do. We’d be lost without them now. So glad we found them. Best move we ever, EVER, made!!! You need 365i in your life.

WordPress is better for business websites. You own your site, have unlimited customisation, better SEO capabilities, and can switch developers anytime. Wix is simpler but locks you into their platform with limited flexibility and export options.
No, WordPress is designed to be user-friendly. Adding pages, updating text, and uploading images requires no technical knowledge. We provide training and documentation so you can confidently manage your own content from day one.
WordPress is secure when properly maintained. Security issues typically come from outdated software, weak passwords, or poorly coded plugins. We implement security hardening, regular updates, and monitoring to keep your site protected.
