Bespoke WordPress Builds
Bespoke web design & custom development.
Fast, hand-coded WordPress sites that turn visitors into enquiries, with automation built in. UK-based, remote, premium.
Everything You Need.
Nothing You Don't.
Every architecture build comes with the absolute essentials baked into the core layer, not bolted on as expensive extras.
Bespoke Visual Architecture
Designed from scratch to match your specific market positioning. We completely refuse to use bloated cookie cutter templates.
Lightning Fast Code
Lean structure and zero plugin bloat. Engineered to load in milliseconds because every second of delay kills your conversion rates.
Mobile First Layouts
Over 70% of web traffic is browsing on their phones. We build for the mobile viewport first, ensuring flawless UX on every device.
Technical SEO Ready
Clean semantic HTML structure, dynamic meta routing, and schema markup built directly into the core framework.
Decoupled Management
We use WordPress purely as a headless style data engine. Your team gets a beautiful backend to easily update copy and build pages.
Active Maintenance
We don't disappear after launch. Our maintenance protocols handle security patches, automated backups, and uptime monitoring.
// Why Cellsior
What you actually get with us.
Bespoke, not a template
Built from scratch around your business and your goals, not a theme a thousand other sites already use. That is what makes it work harder than the competition.
Automation built in
We do not just hand you a website. We wire in the systems that run the business behind it, so leads, bookings and reporting happen on their own.
Honest and clear
Real prices, real timelines, plain English. We tell you the smallest spend that does the job, and we say so if a cheaper route makes more sense for you.
UK focused, built remotely
We build for UK businesses without the central-London overhead, so more of your budget goes into the actual build and less into the rent.
How We Build It.
Three deliberate phases. No mystery. You know exactly what is happening at every stage of the deployment.
// Automation
Automation, built in.
Most agencies hand you a website and walk away. We wire in the systems that run the business behind it, so the site does more than sit there.
Leads to CRM
Enquiries that route themselves
Every enquiry flows straight into your CRM, tagged and followed up automatically, so nothing slips through the cracks.
Booking & payments
Let customers book themselves
Bookings and payments handled on the site, without the email back-and-forth eating your week.
On-site AI assistant
An assistant that never sleeps
Answers common questions and qualifies leads around the clock, so visitors get a reply the moment they ask.
Plain-English reporting
Know what is working
Clear reports on what is driving enquiries, sent to your inbox, with no dashboards to decode.
