Business websites
Fast, search-ready websites that present your business properly: clear structure, sharp design and content your team can update without calling a developer.
Websites that win customers and web applications that run the business, designed and engineered by one team in London.
What this covers
The web is where most businesses are judged first. We design and engineer both sides of that judgement: the website that earns trust and ranks in search, and the web application behind the login that does the real work, from bookings and orders to accounts, billing and reporting.
One senior team owns the whole thing: design, content structure, engineering, hosting, search and performance. Nothing is handed between agencies, so nothing gets lost between them, and the platform keeps being looked after once it is live.
Web applications
Full products in the browser: dashboards, portals and software-as-a-service platforms with real accounts, real data and real workloads.
E-commerce
Online shops and checkouts built around your catalog, stock and delivery rules, connected to your payment provider so money moves correctly every time.
Customer portals
Secure areas where your customers log in, see their own orders, documents and invoices, and serve themselves instead of emailing you.
Booking and ordering systems
Appointments, reservations and orders taken online, checked against real availability and confirmed by email or text without anyone retyping them.
Content management
An editing system shaped around your content, so publishing a page, a product or an article is a few minutes of work for the person who owns it.
Multilingual websites
One site in several languages and regions, with the right language tags so each audience reaches its own version from search.
Redesigns and migrations
An existing site rebuilt or moved to a modern platform without losing the search rankings, links and data it has built up.
Performance first
Built to pass Core Web Vitals with room to spare: fast first paint, no layout jumps and smooth on mid-range phones.
Search-ready from day one
Structured data, sitemaps, language tags and clean addresses from the first release, so search engines and AI assistants can read the site and cite it.
Accessible to everyone
Designed and tested against WCAG 2.2 AA: readable contrast, full keyboard use and screen reader support, because an inaccessible site turns customers away.
Secure by default
Encrypted connections, hardened headers, protected forms and the minimum of personal data, held in line with UK GDPR.
Built to scale
The same platform holds up on launch day and on your busiest day, with staging, monitoring and one-step rollbacks in place.
Measured
Privacy-respecting analytics and search reporting set up properly, so decisions are based on what visitors actually do.
Discovery
We learn the business, the audience and what the site has to achieve, and agree the pages, features and integrations in writing.
Design
Layouts and a design system built around your brand, reviewed on real devices before production code is written.
Build
Short sprints, each one deployed to a private preview you can click through, with your feedback taken in as we go.
Launch
Content moved, redirects mapped, search and analytics connected, and the site released with a plan to roll back if anything is wrong.
Run and improve
Hosting, updates, monitoring and improvements after launch, so the site stays fast, secure and current.
A website presents your business; a web platform runs it. Webmasters LDN builds both: fast, search-ready websites, and web applications behind a login, such as dashboards, portals and software-as-a-service products with real accounts, data and workloads. The same senior team designs, engineers, hosts and maintains each one.
Yes. Webmasters LDN is a software development company in London that designs and builds websites, web applications, online shops and customer portals for businesses in the UK and worldwide. One senior team handles design, engineering, hosting and search, and keeps the platform running after launch.
We choose the technology for each project rather than out of habit. Most of our web platforms are built in TypeScript with React and Next.js, on managed cloud hosting with a Postgres database, because that combination is fast, well supported and easy to hand over. Where a project needs something else, we use that.
Yes. We build online shops, checkouts, subscriptions and billing flows connected to your payment provider, and secure customer portals where clients log in and serve themselves. Money flows are engineered carefully so payments move correctly every time, and everything is built to hold up from launch day to your busiest day.
Every Webmasters LDN site ships with structured data, clean addresses, sitemaps and language tags from day one, so search engines and AI assistants such as ChatGPT, Google AI Overviews and Perplexity can read and cite it. We build for Core Web Vitals and write answer-led content that earns rankings and citations.
Yes. Before anything moves we record every address the current site has, its rankings and its links, then map each old address to its new one with permanent redirects. Content, page titles and structured data are carried across, and search performance is monitored after launch so any drop is caught and fixed early.
A business website usually takes a few weeks from agreed scope to launch, depending on the number of pages and how much content is ready. A web application is delivered in stages, with a first working version early so you can use it and shape what comes next. We give a timeline with the quote.
Yes. Webmasters LDN hosts, monitors, updates and improves the platforms it builds, on a monthly arrangement agreed with you. Security updates, backups, performance checks and small changes are part of it, so the site keeps working as well as it did on launch day.
