Our specialism
Websites for beauty salons, clinics and massage therapists.
Treatment menus with prices, booking that works with Fresha or Treatwell, gift vouchers, your Instagram and reviews live on the page, and the local search work that gets you found for your town. Seven salon and clinic sites built and looked after.
Our specialism
Websites for builders, fitters and trades.
A page for every job you want more of, your towns named properly, your work in a gallery you update from your phone, reviews on the page, and a tap-to-call number and quote form on every screen. Nine trade and construction sites built and looked after.
Since 2009, one promise.
You talk to the person doing the work.
CSM was founded by Chris Moss in 2009 to give businesses professional, affordable websites backed by honest advice and dependable support. Chris still leads every project personally — no account managers, no outsourcing — with senior IT leadership experience in technology delivery, cybersecurity and complex digital systems behind him. That is why performance, security and reliability are planned from the start, not bolted on.

FAQs
How much does a website typically cost?
Websites start at £500 for a small, well-built site and most projects land at £1,000 or under. Every project is quoted fixed, in writing, before anything starts — so you know the number before you commit. Full pricing ›
Can I spread the cost?
Yes. Projects are split into three staged payments tied to milestones rather than one bill on launch day. Or pay monthly instead: £69 a month for 12 months with nothing upfront, and the site is yours after that. From then on you can stay at £69 a month with maintenance included, or drop to hosting only at £95 a year. If you buy outright, ongoing hosting and support is a monthly plan from £25. See how payments work ›
How long does a project take?
Most projects take around two weeks, depending on how ready your content is. A small site can be turned around in a week; larger builds take a little longer depending on scope. You get a written timeline and clear milestones from day one.
Who will I actually be dealing with?
Chris Moss, from planning and design through to launch and ongoing support. No account managers, no outsourcing.
What happens after launch?
UK hosting, updates, backups and monitoring are handled for you; content changes are a quick email away.
Do I own my website?
Yes, completely — the design, the content and the domain — and you can move it to another host at any time. Buy outright and it is yours from launch; pay monthly and it is yours after 12 months.
