Affiliate Marketing In The UK: How It Works And The Best Programmes To Join

Affiliate marketing in the UK is one of the simplest ways for a small business, blogger or creator to earn extra income from content they already make. You recommend products you genuinely use, share a tracked link, and earn a commission when someone buys. Businesses can also run their own affiliate programme and pay others to bring them customers.

This guide explains how affiliate marketing works, the UK affiliate programmes worth joining for small business owners, how to start, and the rules you need to follow.

Some links in this article are partner links. If you sign up through them we may earn a small commission at no extra cost to you. We only recommend tools we use ourselves.

What Is Affiliate Marketing?

Affiliate marketing is a partnership between a brand and a person or business that promotes it. The promoter (the affiliate) shares a unique link. When someone clicks it and buys or signs up, the brand pays the affiliate a commission.

It works for both sides. The brand only pays when it gets a result, and the affiliate earns money from honest recommendations.

How Affiliate Marketing Works In The UK

1. You join a programme, either directly with a brand or through an affiliate network.
2. You get a tracked link that records who sent each visitor.
3. You share it in blog posts, emails, videos or social media posts.
4. Someone clicks and buys, usually within a set time window.
5. You earn a commission, either a percentage of the sale or a fixed amount per sign-up.

Many UK brands run their programmes through affiliate networks such as Awin, Impact, CJ and Partnerize. Others, especially software companies, run their own referral programmes directly.

Best Affiliate Programmes UK Small Businesses Can Join

The best programmes are for products your audience already needs. If you run a business or write about business, these are tools that small business owners use every day. They’re the same tools we recommend to our own clients, so you can sign up through our links to try them.

Once you use a tool and like it, check its website for a “partners”, “affiliates” or “refer a friend” page. Commission rates and terms change, so always read the current terms before you start promoting.

For more detail on each tool, see our guide to marketing tools for small business.

How To Start Affiliate Marketing In The UK

1. Pick A Topic Your Audience Cares About

Stick to what you know. A bakery might recommend kitchen equipment, a consultant might recommend business software. Trust matters more than the size of the commission.

2. Only Promote Products You Use

Your recommendations are only as good as your reputation. Promote tools you’ve tried and would recommend to a friend.

3. Create Genuinely Helpful Content

Guides, comparisons, tutorials and “tools I use” pages work best. Write for the reader first and add links where they’re actually useful.

4. Get Found On Google

Most affiliate income comes from content that keeps bringing in visitors from search. Research what people are searching for with a tool like Semrush and answer their questions clearly.

5. Build An Email List

An email list lets you share useful recommendations with people who already trust you, without relying on social media algorithms.

Affiliate Marketing Rules In The UK

UK advertising rules say affiliate content must be clearly identifiable as advertising. In practice, that means:

• Label it clearly: use “Ad” or a clear disclosure near the top, before people click a link.
• On social media: label affiliate posts as ads, for example with “Ad” at the start of the caption.
• Be honest: don’t make claims about a product you can’t back up.

The Advertising Standards Authority (ASA) publishes guidance on affiliate marketing. It’s worth reading the ASA website before you start.

Should Your Business Run Its Own Affiliate Programme?

If you sell online, an affiliate programme can bring in customers through bloggers, creators and other businesses, and you only pay when you make a sale. It works best when:

• you have healthy margins to share a commission
• your website tracks sales reliably
• you can give affiliates good content, images and offers to promote

You can start small with a simple “refer a friend” offer before moving to a network. It sits well alongside influencer marketing and your other marketing channels.
