Why UK Businesses Choose Mtoag for Website Development
Three things that separate us from every other web development agency in the UK.
Fixed-Price. No Surprises.
Before writing a line of code, we produce a Technical Specification — a fixed-price, fixed-scope document listing every feature, screen, API integration, and delivery milestone. You sign it. We build it. The price you sign is the price you pay.
150+ In-House Engineers. No Subcontractors.
100% of Mtoag's engineering work is done by direct employees — never freelancers, never agencies, never offshore subcontractors. Your senior developer has worked at Mtoag for an average of 4+ years.
Full IP Ownership from Day One.
Your website's source code, design files, and all intellectual property transfer to you on final payment. We sign an NDA before any technical discussion. No vendor lock-in.
The Tech Stack That Powers Our Solutions
Sixteen years of production experience across mobile, web, enterprise, open-source, and search — every technology below is one we ship for UK clients, not just list on a page.
From native performance to cross-platform speed, we build mobile experiences that feel first-class on every device.
Modern, fast, accessible websites and web apps built on frameworks that scale with your business, not against it.
Enterprise-grade architecture built for security, compliance, and systems that need to talk to each other reliably.
Proven open-source platforms customised and hardened for real commercial traffic — not a stock install.
Technical SEO built into the codebase from day one — because rankings are an engineering outcome, not a marketing add-on.
All versions current as of July 2026. We track and adopt major releases within 90 days.
Website Development Case Studies
All projects live in production since launch.
Our Website Development Process
The same six-step process on every project. No improvising. No scope creep. No surprises.
Discovery and Technical Scoping
A structured 45-minute discovery call followed by a written Technical Specification defining every page, feature, API integration, performance target, and accessibility requirement. You review and sign it before we charge a penny.
UI/UX Design and Prototype
High-fidelity Figma prototypes covering every page template and user flow across mobile, tablet, and desktop. Accessibility and Core Web Vitals are considered at the design stage — not added later.
Agile Development and Build
Two-week sprints with a live staging environment accessible 24/7. Weekly video demos and Slack access to your project manager. All code reviewed by a senior engineer before it merges.
Quality Assurance Testing
Automated unit and integration testing, manual regression across 8 browser/device combinations, Lighthouse performance audit, WCAG 2.2 AA accessibility audit, and load testing to 500 concurrent users minimum.
Launch and Performance Monitoring
Zero-downtime deployment with instant rollback capability. Google Search Console and Analytics verified on launch day. Core Web Vitals monitored for 30 days post-launch, with fixes included in the launch fee.
Support and Ongoing Development
Post-launch SLA options from 8-hour response to 24/7 monitoring. Monthly security patches, dependency updates, and performance reports. Ongoing feature development available on sprint retainer.
All timelines are fixed in the Technical Specification.

What Our Web Development Clients Say
Website Development Questions Answered
10 direct answers. No sales language.
A standard website takes 6–12 weeks from project kick-off to launch. Simple brochure sites: 4–6 weeks. Complex web applications with custom functionality: 12–20 weeks. At Mtoag, every project receives a fixed timeline in the Technical Specification document before development begins.
A website primarily delivers information to passive readers — blogs, company pages, portfolios. A web application allows users to interact, input data, and receive dynamic responses — dashboards, booking systems, SaaS platforms. Most modern projects require a hybrid of both.
Mtoag builds with Next.js 14, React 18, TypeScript, Node.js, and PostgreSQL for web projects. E-commerce uses Shopify or WooCommerce. CMS projects use Sanity or Contentful. All projects include automated testing, CI/CD pipelines, and deployment to AWS or Vercel.
Yes. Next.js (App Router) is Mtoag's primary web framework — used on 70% of projects since 2022. React powers the frontend, delivering the Core Web Vitals performance scores Google rewards with higher rankings.
Every Mtoag website is built with technical SEO built in — semantic HTML, structured data schema, Core Web Vitals optimisation, and proper heading architecture. SEO is an engineering decision, not a post-launch add-on.
All Mtoag web projects are built to WCAG 2.2 Level AA accessibility standards — the level required by UK public sector organisations under the Public Sector Bodies Accessibility Regulations 2018.
Yes. Mtoag's website rescue and optimisation service starts with a free technical audit covering performance, accessibility, security, and SEO. Projects start within 5 business days of contract signing.
Core Web Vitals are three performance metrics Google uses as ranking factors: Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Mtoag builds all websites to achieve 90+ scores on all three.
Headless CMS separates the content management interface from the website's presentation layer. Editors update content in a dashboard; the website fetches and displays it via an API — faster, and reusable across channels.
Check five things: a documented fixed-price process, whether engineers are in-house, visible Lighthouse scores on live projects, your named UK project manager, and full IP ownership on completion.
