What we do

Wedesign,buildandrankwebsitesforthebusinessesthatbuildBritain.

COS Digital is a UK studio for the firms that pour the concrete, fix the boiler, let the flat and sign off the survey. We design and hand-build fast, accessible websites, then structure them so Google — and the people searching it — can find you in the towns you actually work in. One team, no agency jargon, and a site that looks like the biggest firm on the street.

Start a project

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.
