Affiliate programme management UK: checklist before outsourcing

What to take away

The work behind the retainer

Affiliate programme management is not one job. It covers publisher recruitment, commission validation, tracking checks, creative approvals and monthly reporting.

Someone also has to chase missed sales, police voucher misuse and keep publisher terms current. A merchant with a few dozen active publishers can absorb that in a part-time role, but once hundreds are live it becomes a full-time job.

What an agency quote should spell out

Merchants that outsource affiliate management in the UK usually buy three things: a monthly retainer, a share of commission, and a setup or migration fee. The commission share is often tiered, so the percentage falls as tracked revenue climbs.

Ask for a written schedule covering minimum term, notice period and what happens if targets are missed. Agencies like Silverbean, Genie Goals and Acceleration Partners operate here.

Ask whether network fees sit inside or outside the retainer; read how Awin and Tradedoubler bill merchants before you compare quotes.

Comparing an agency quote with an in-house hire

Add the variable line to the fixed line for each route, then compare twelve-month totals. The agency route usually wins at low commission volume, while an in-house hire wins once the retainer exceeds a loaded salary.

Build the two totals like this, using your own quotes and payroll figures:

For the pension line, the legal minimum under automatic enrolment is set out in the government's guide to workplace pension contributions: from April 2019 the employer pays at least 3%, the employee 5%, for a total minimum contribution of 8%.

In-house pay and the costs that sit outside salary

In-house pay for an affiliate programme manager depends on region, sector and how much of the role is commercial. The ONS publishes earnings and working hours data by occupation and region in its Annual Survey of Hours and Earnings (ASHE), which is a stronger starting point than a single advert: look up the marketing occupation closest to the role and your region, then use the median rather than the top of the range. As a whole-economy reference point, not a rate for the role, the ONS employee earnings bulletin for 2025 puts median gross annual earnings for full-time employees at £39,039 in April 2025.

Employer National Insurance, pension contributions, software seats, conference tickets and training sit on top of the headline salary. For the 2026 to 2027 tax year, HMRC's rates and thresholds for employers set the secondary threshold at £5,000 a year, and an employer pays 15% National Insurance on a category A employee's earnings above it. Budget for holiday and sickness cover, because a single hire has no backup.

A five-step way to decide

What to ask a UK agency before you sign

When a hybrid model makes sense

Plenty of UK merchants start with an agency and hire later. That handover works best when the agency is contracted to document recruitment sources, publisher terms and reporting definitions. Write those clauses in at the start, because exit terms are hard to negotiate once notice is served.

Another option is a freelancer on a day rate handling validation and reporting while you run recruitment yourself. That suits shops where commission volume is steady but not yet large enough for a full-time salary.

Compliance duties that do not transfer

An agency can run the programme, but your business still owns the customer relationship and the data. Under the UK GDPR you need a lawful basis for processing and a clear record of what customer data is shared with networks and publishers, and the ICO guide to the UK GDPR sets out those duties.

Affiliates must label paid links and advertorials, and the CAP Code applies to what they publish. The ASA advice on affiliate marketing explains the disclosure rules.

Commission also feeds into your VAT position. If affiliate income helps push turnover past the registration threshold, the VAT rules on affiliate marketing explain when registration becomes necessary. HMRC's guidance on when to register for VAT sets the test: you must register if your total taxable turnover for the last 12 months goes over £90,000, or if you expect it to go over £90,000 in the next 30 days.

Common questions

Is outsourcing affiliate programme management cheaper than hiring?

Not automatically. An agency usually costs less at low commission volume, while a loaded in-house salary becomes the cheaper option once tracked revenue is high enough to cover it.

What does a UK agency retainer include?

Most retainers cover publisher recruitment, commission validation, tracking checks and monthly reporting. Ask whether network fees and creative production sit inside the fee or are billed separately.

Can I move from an agency to an in-house manager?

Yes, and it is a common path. Insist on exit terms that hand over the publisher list, contact history and reporting definitions.

Do I need a full-time affiliate programme manager?

Only when the workload justifies the cost. Below that level, a part-time hire, a freelancer or an agency will usually cover recruitment and validation.
