36.8% of households in Markham live in social rented homes, against 16.5% in Wales. Web design in Markham works best when the site answers the questions local customers actually ask. Our £69 plan covers the website or online shop, your domain, email and hosting, ready within 3 working days on a temporary link.

No setup fee: you only pay the £69 monthly fee once you have approved your website.

The legal basics for Markham businesses online

A website does not need a special licence, but the business behind it follows the usual rules. A few that come up often:

  • A limited company has to be registered with Companies House before it starts trading; registering online costs £100. GOV.UK: register a limited company
  • When you sell online, you must tell the customer they can cancel their order up to 14 days after it is delivered, and they do not need to give a reason. GOV.UK: online and distance selling
  • Under the Digital Markets, Competition and Consumers Act 2024, whose rules on this came into force on 6 April 2025, you must not commission fake reviews or pretend to be a consumer leaving one, and if you publish consumer reviews you have to take appropriate steps to make sure they are genuine. GOV.UK: unfair commercial practices
