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.

01
Design

Bespoke Visual Architecture

Designed from scratch to match your specific market positioning. We completely refuse to use bloated cookie cutter templates.

02
Speed

Lightning Fast Code

Lean structure and zero plugin bloat. Engineered to load in milliseconds because every second of delay kills your conversion rates.

03
Mobile

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.

04
SEO

Technical SEO Ready

Clean semantic HTML structure, dynamic meta routing, and schema markup built directly into the core framework.

05
CMS

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.

06
Support

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.

Discovery & Strategy 1
PHASE 01 // WEEK 1
We Map The Terrain.
We map out the site architecture, content structure, and conversion strategy before a single pixel is designed. Includes deep-dive brand questionnaires, competitor audits, and wireframe sign-offs.
Design & Build 2
PHASE 02 // WEEKS 2–4
We Construct The Engine.
We design high-fidelity mockups for approval, then hand-code the entire platform from scratch. We ensure zero bloated plugins and guarantee ultra-fast mobile optimization.
Launch & Grow 3
PHASE 03 // WEEK 5+
We Flip The Switch.
We run final QA, migrate your DNS to live hosting, hand you the keys, and activate our ongoing maintenance protocols to ensure continuous up-time and security.

// 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.

Frequently Asked Questions.

Everything you've wanted to ask about getting your site built.

We build on WordPress, the world's most widely used CMS. It's flexible, easy to manage once handed over to you, and has a huge support ecosystem. You'll be able to update your own content without needing us for every small change.
Every site we build is fully responsive and tested across mobile, tablet, and desktop. Most of your visitors will be on mobile, so this is never an afterthought.
Yes. All our sites are built with solid on-page SEO foundations, fast load times, clean code, proper heading structure, meta data, and schema markup where relevant. This gives you the best possible starting point to rank in search.
Mostly just your logo, any photos you have, and a rough idea of what you want the site to do. We'll guide you through the rest, including copy direction if you're not sure what to write.
Absolutely. If your current site isn't performing or just looks outdated, we can audit it, identify the issues, and either rebuild it properly or make targeted improvements depending on what makes most sense for your budget.
Most of our bespoke sites land between £4,000 and £10,000, depending on the number of pages, the custom features, and any automation wired in. We scope it to your goals and budget before any work starts, so there are no surprises.
Yes. We can layer automation onto a site you already have: lead capture into your CRM, booking and payments, an on-site AI assistant, or automated reporting, without rebuilding from scratch. We start by mapping what would save you the most time.
