Built, not bought
Hand-coded for speed and control. No bloated builders, no template tax.
Studio
Built to be found.
COS Digital is a UK web studio for the businesses that build Britain — construction, trades and home services.
Our belief
A local business should look as good online as the work it does in person — and be just as easy to find.
So we hand-code fast, search-ready sites for the firms that build Britain. This very site is the proof.
How we work
One small, senior team across the whole job — discovery, design, build and SEO — so nothing falls between the cracks and you always know who you’re talking to.
The stack
Modern, static-first architecture (Next.js on Vercel), real performance budgets, accessibility baked in, and analytics that respect consent.
Who's behind it
.
COS Digital is run by one person who does the whole job — discovery, design, build and search — rather than passing you between an account manager and a queue.
The route here ran through quantity surveying, not through an agency. Years of reading drawings, pricing works and sitting on the other side of the table from contractors is why this studio builds for construction, trades and property rather than for everyone.
That background shows up in the work: proof before polish, plain language over jargon, and an understanding that a website is a tool for winning jobs, not a brochure.
Values
What we stand for.
Found by design
SEO engineered in from the first commit — never bolted on at the end.
Proof over promises
We lead with evidence: real projects, real results, real accreditations.
Plain language
We talk like the trades we build for. No jargon — just clear value.
How we build
Design with intent, built to measure.

Testimonial 01 of 01: Theophilus Jones, Jones Transport and Cleaning Services
Most projects run 3–6 weeks from kick-off to launch, depending on scope and how quickly we get your content and feedback. We set a clear timeline at the start and keep you updated at every stage.
It depends on what you need — most of our sites land between £1,000 and £6,000. Tell us about your project, and we’ll give you a fixed, no-surprises quote before any work begins.
Yes. We’ll be honest about what’s realistic and can phase the work so you start with the essentials and grow from there.
No. Design, build and SEO are all handled in-house by a senior web developer — so the quality stays consistent and you always know exactly who you’re talking to.
Web design, web development, SEO, Google Business Profile setup, business email, content creation and ongoing support — everything you need to get online and get found. See the full list on our services page.
Not at all. We work with businesses right across the UK and run everything remotely, with calls and screen-shares whenever you need them. Where you’re based makes no difference to the result.
Typically a deposit to book the work in, a stage payment partway through, and the balance before launch. It’s all set out clearly in your proposal — no hidden fees.
As many as the project needs. We’d rather over-communicate than leave you guessing — calls, screen-shares and updates are part of the service, not an extra.
Of course. Start a project or drop us a line, and we’ll book a call at a time that suits you — no obligation and no hard sell.
