The legal basics for South Mimms businesses online

Some homework for South Mimms businesses before the website goes live:

  • A limited company has to be registered with Companies House before it starts trading; registering online costs £100. GOV.UK: register a limited company
  • Organisations, including sole traders, that use personal information need to pay a data protection fee to the ICO, although many can rely on an exemption; the tier 1 fee is £52. ICO: data protection fee
  • You must not send marketing emails or texts to individuals without specific consent; there is a limited exception for your own previous customers, often called the soft opt-in. ICO: email marketing

General information, not legal advice. Each link goes to the official page, where the details for your situation are.

Before you sign up: common questions

South Mimms is small. Do I really need a website?

Yes. Customers from across Hertsmere search before they travel, and a website is how they find you. It also answers the basics (hours, prices, location) without a phone call.

How many email accounts do I get?

As many addresses on your domain as you need, sharing 5 GB in total, with webmail and spam filtering.

When does the site go live?

Within 3 working days of receiving your material, the website is ready on a temporary link. It goes live on your domain after you approve it and the first monthly fee is paid.

Is there a minimum contract?

No lock-in. The plan is month to month at £69, with nothing to pay before you approve the website.

Can customers order from my website?

Yes, an online shop costs the same £69 a month as a regular website: a catalogue of your products, basket and online payment.

Can I add a page for the area I cover around South Mimms?

Of course. Email us the towns you serve (say Potters Bar, Shenley and Borehamwood) and we put them on a page of their own.

Do I pay anything to get started?

No. No setup fee: you only pay the £69 monthly fee once you have approved your website. No lock-in contract. You can stop the service whenever you need to.
