Event marketing agency retainer vs project fees: UK comparison
Compare event marketing agency retainer and project fees in the UK, including day rates, London and regional differences, VAT at 20% and contract terms to check.
What to take away
- A retainer buys continuitya named team, an agreed number of hours each month and priority on event dates.
- A project fee buys a defined outcome, such as a conference, a product launch or a stand at an exhibition.
- Most UK agencies price projects from a day rate plus a management fee, then add VAT where it applies.
- Get the fee model, the inclusions and the re-charge rules in writing before comparing two agencies.
What sits inside an event marketing agency fee
Agency quotes usually split into four parts: time, management, third-party costs and expenses. Time is a day rate multiplied by the days the team expects to spend on your account. That rate reflects seniority and specialism.
Four parts of an agency fee
- Time: day rate x days
- Management: % of work total
- Third-party: net plus handling
- Expenses: travel and subsistence
Management or production fees cover project oversight, supplier coordination and reporting. They are usually quoted as a percentage of the work total, so ask which costs the percentage applies to. Some agencies charge a flat fee instead.
Third-party costs such as venue hire, AV, stand build and print are normally passed through at net cost plus a handling charge. The expense policy matters more than the headline rate, because travel and subsistence claims add up quietly.
Before you ask for a fee, write a clear agency brief so both sides price the same scope. A vague brief invites padded day estimates.
Under a retainer, the same work is grouped into a monthly fee with an agreed number of hours. Unused hours may roll over for one month or be lost.

Retainers usually name a team: an account lead, a producer and a specialist or two. Project work often draws on whoever is free, so ask who will actually deliver the work.
A project fee suits a single flagship moment. It gives a fixed price to take to finance, but any change to scope becomes a variation to sign off before work continues.
Where London and regional rates differ
Agency day rates absorb salary, office and travel costs. London agencies carry higher overheads, so a mid-weight team on a London rate usually sits above a regional equivalent. The figures below are illustrative, not a published market average.
London and regional rates
- £700 to £950a dayLondon, mid-weight team
- £500 to £700a dayRegional England, comparable team
- 30% to 50%%Senior strategist or creative director
Travel can reverse the gap. A regional agency working a London venue may charge travel days that a London agency would not, which narrows or closes the difference.
A worked example: a one-day conference
- Strategy and creativesix days at £750, giving £4,500.
- Production managementten days at £650, giving £6,500.
- On-site deliveryfour days at £650, giving £2,600.
- Fee subtotal£13,600.
- Management fee at 12% of the subtotal£1,632, bringing the total to £15,232.
- VAT at 20% on agency fees£3,046.40, making the invoice £18,278.40.
Venue, catering, AV and print sit outside this example and pass through at net plus handling.
Contracts, VAT and the small print
Agency fees carry VAT where the agency is registered. GOV.UK's VAT rates page sets the standard rate at 20%, with reduced and zero rates for specific supplies.
The Consumer Rights Act 2015 requires services to be performed with reasonable care and skill. If delivered work falls short of the agreed scope, that duty is your starting point for a remedy.
Retainers that include registration pages and follow-up email are processing personal data on your behalf. The ICO's UK GDPR guidance sets out what a written processor agreement needs to cover.

Common questions
Should we start with a project before committing to a retainer?
Yes. One event gives both sides evidence on working style, reporting quality and cost control before you commit to a longer term.
Do UK agencies add VAT to quoted fees?
If the agency is VAT registered, yes, unless the quote states that the figure already includes VAT. Ask for net and gross figures on every proposal.
Why is a London quote higher than a regional one?
Day rates absorb salary and office costs, which are higher in the capital. For a London venue, travel and accommodation can still make a regional agency dearer overall.
Can we move from a retainer to project fees mid-term?
Only if the contract allows it. Most retainers run for 6 or 12 months with a notice period, so vetting questions for shortlisted agencies should include the exit terms.
