Fix the Front-End Issues Costing You Visitors
Most UK visitors browse on a phone. If your website squashes, stretches or crawls on a small screen, people leave before they read a word. We rebuild layouts so they respond properly, compress heavy files, tidy up old code and test across Chrome, Safari, Edge and Firefox. Faster, cleaner pages also support your rankings, especially alongside our SEO services.
We also rescue old Flash content. Flash reached the end of its life in 2020, which left plenty of games, animations and training courses unusable. We rebuild them in HTML5 so they run again on modern browsers and mobile devices.
Not Mobile Friendly

Tested so every visitor sees the same thing.

FAQs
What is HTML5 development?
HTML5 development is building websites, web apps and interactive content with the latest version of HTML, along with CSS3 and JavaScript. It runs in every modern browser without plug-ins. It also helps pages load quickly and rank well.
Can you convert Flash content to HTML5?
Yes. We rebuild Flash animations, games and e-learning modules in HTML5 so they work again in modern browsers and on mobile devices. We keep the look and feel your users know.
Why isn’t my website mobile friendly?
Usually it’s because the site uses fixed-width layouts or outdated code. A responsive HTML5 rebuild fixes the layout so it adapts to any screen. It also improves how Google sees your site.
Can HTML5 web apps work offline?
Yes. Using service workers, HTML5 apps can store content on the device and keep working without a connection, then sync when you’re back online. This is ideal for field teams and training.
Do HTML5 games work on iPhone and Android?
Yes. HTML5 games run in Safari, Chrome and other mobile browsers, so players don’t need to download anything from an app store. Scores and leaderboards can be added too.
How much does HTML5 development cost?
Landing pages often start around £500, responsive websites from about £3,000, and web apps or games from around £10,000, depending on features. You’ll get a fixed quote before work begins.
