For most UK service businesses, the real question is not whether you can get a website cheap. It is whether the site will actually make you look trustworthy, explain your offer clearly, and turn visits into enquiries.
In practice, most brochure and lead-generation sites land somewhere between £1,000 and £5,000. That is the range where strategy, copy, mobile design, SEO setup, and trust signals usually start being handled properly instead of patched together.
