A look at what I've built for other UK businesses, from a charity's Ad Grant win to a bespoke contract signing app. Every one of these is a real client, and you can click through to the live site.

What each business needed, what I built, and what changed.
Full overhaul for a registered UK children's charity, including compliance work, donation setup, Gift Aid integration, and support with the Google for Nonprofits application, which went on to unlock $100,000 a year in free Google Ads.
Outcome: $100k Google Ad Grant secured
Built the main business website and a bespoke digital contract signing system: a genuinely custom app, not a bolted-on template or third-party tool. Clients receive a unique link, sign online, and the completed contract is saved directly into their process.
Outcome: Custom-built, not templated
Built a custom number plate builder with a live-updating preview, plate size options, and a streamlined checkout with UK-wide delivery.
Outcome: Live plate preview, smoother checkout
Built a full-service renovation and refurbishment site with a services overview, before-and-after project galleries, and a quote enquiry flow covering London and the Southeast.
Outcome: Clear service showcase, easier quote requests
Website build for an equestrian stables business, giving them a clear online presence for bookings and enquiries.
Outcome: Clearer website, easier enquiries

“I've been using Lee Day for about 3 years now and he has just rebuilt a site for a new venture. Can't recommend enough. Very informative, fairly priced and a pleasure to work with.”
