Affiliate Commission Rates in the UK: Models and Benchmarks Explained
An affiliate commission rate is the amount an advertiser agrees to pay a partner for an eligible outcome, commonly a validated sale, lead or subscription. There is no single UK-wide commission rate that is appropriate for every product, publisher or business model.
The most useful starting point is contribution margin and customer value—not an unsourced average from another programme.
Common affiliate commission models
| Model | How payment is calculated | Often used for |
|---|---|---|
| Percentage of sale | Agreed percentage of eligible order value | Ecommerce purchases |
| Fixed amount per sale | Flat payment for each validated order | Subscription and defined-value products |
| Cost per lead | Payment for an eligible, qualified lead | B2B and considered purchases |
| Recurring commission | Payment on eligible subscription renewals | Software and membership products |
| Tiered commission | Rate varies by volume, customer type or partner | Programmes seeking specific behaviours |
| Hybrid placement + CPA | Fixed exposure fee plus performance commission | Selected editorial or creator campaigns |
Why generic commission benchmarks can mislead
A published rate may apply only to new customers, selected products, a promotional period or a particular partner type. It may also exclude VAT, shipping, returns or discounted products from the commissionable amount.
Therefore, comparing two programmes simply because one pays 5% and another pays 10% can be meaningless without knowing margins and rules.
AMA does not present the illustrative numbers below as verified UK industry averages. Any future benchmark report should identify its source, sample size, date, category definitions and methodology.
Work backwards from margin
Suppose a hypothetical product sells for £100 excluding VAT and has £42 contribution before marketing. If the advertiser wants to retain at least £25 after acquisition-related costs, the maximum combined acquisition allowance is £17.
If network and management costs attributable to the sale are estimated at £5, the remaining publisher commission allowance is £12, equivalent to 12% of the £100 eligible sale value.
This is a simplified example. Real businesses must account for customer lifetime value, refunds, returns, product mix and fixed costs.
Should different partners receive different rates?
Often, yes. An editorial partner introducing new customers may justify a different rate from a partner primarily assisting existing customers at checkout. A B2B referral may warrant a fixed qualified-lead payment rather than an order percentage.
Set tiers around commercial objectives and measurable behaviour, not assumptions that one entire publisher category is always incremental.
New versus returning customers
Some advertisers pay a higher commission for verified new customers. This can align incentives with acquisition goals, but the tracking system must reliably distinguish first-time purchasers from repeat buyers.
A new customer is not necessarily an incremental customer. Combine customer segmentation with other evidence when evaluating value.
Important programme rules
Specify whether commission is calculated on gross or net sales, whether VAT and shipping are excluded, how discounts affect eligibility, the returns and cancellation policy, attribution windows and the validation timetable.
For subscription products, define trial conversion, early cancellation, renewals and any clawback conditions. For B2B leads, define qualification, duplicate handling and the stage at which commission becomes payable.
How to test commission changes
- Establish baseline performance and contribution by partner segment.
- Choose one clear objective, such as new customers or category growth.
- Define the partners and time period eligible for a change.
- Document other promotions running during the test.
- Review validated sales, total costs, customer quality and incremental evidence.
- Keep or reverse the change based on economics, not topline volume alone.
Frequently asked questions
Is a higher commission always better for recruitment?
No. Audience relevance, product demand, conversion rate, creative support and relationship quality can matter as much as the headline rate.
Who pays affiliate commission?
The advertiser ordinarily funds eligible publisher commission under the agreed programme terms. Agency and network fees may be additional.
Can commission rates change?
Often yes, subject to contractual terms, partner notice requirements and programme rules. Clear communication is essential.
Are there reliable UK commission averages?
Published figures exist for particular networks and sectors, but methodologies differ. Treat any cross-sector number cautiously unless the underlying data and definitions are transparent.
