Three ways the sponsorship rates market size in England gets overstated
The sponsorship rates market size in England depends on which data you count. Here is what ONS, IAB UK and Acas figures can and cannot tell you.
What to take away
- No official England figure exists. Use UK totals as a ceiling or build a bottom-up estimate from counted buyers.
- Official business population data sizes the advertiser base, which tells you how many buyers exist, not how much they spend.
- Employment status decides whether a rate must cover employer costs, so mixed samples produce mixed averages.
- Treat every figure as a floor, a range or a direction, and name its source and date beside it.
What a market size figure measures
A market size is the total value of deals in a period, not an average price. A UK number used for an England claim is an estimate, not a fact.
Market Size vs. Deal Fee
Market size
- What it is
- Total deal value
- Period
- A set period
- Scope
- All deals counted
- Common error
- Compared to a fee
Deal fee
- What it is
- Single deal price
- Period
- One agreement
- Scope
- One rate
- Common error
- Compared to a total
Before you build a model, it helps to see how the England market guide frames the picture. The boundaries you set there decide which totals you can defend.
Three mechanisms overstate an England sponsorship market size.
- UK-wide totals from platform and agency reporting include Scotland, Wales and Northern Ireland. They overstate England unless you adjust them.
- The ONS UK BusinessActivity, Size and Location release, reference date March 2024, counts employers, not deal spend. Using its England SIC 2007 code 73.11 employment size band 10 to 49 count as a market size inflates the total.
- Blending self-employed creator rates with employed or worker rates under Acas employment status rules mixes two cost bases. The average used to scale the market can be overstated.
At a labelled illustrative £10,000 to £30,000 per buyer a year, a count of 8,000 buyers gives £80m to £240m, not an official England market size.
Why England figures are rarely published on their own
Advertiser budgets are usually reported for the UK as a whole. Agencies buy across borders, platforms bill in one currency, and campaign reporting rarely splits spend by nation. UK-wide figures include Scotland, Wales and Northern Ireland, so they overstate an England-only market unless adjusted.
Sizing the advertiser base with official data
The ONS business activity, size and location dataset is the UK Business: Activity, Size and Location release, reference date March 2024. It counts businesses by activity, size and location, and can be filtered to England.
That gives a denominator. For a worked illustrative England estimate, assume the ONS England country filter, SIC 2007 code 73.11 and employment size band 10 to 49 returns 8,000 businesses. This count is illustrative, not an ONS figure. At a labelled illustrative £10,000 to £30,000 a year per buyer, the range is £80m to £240m.
Keep the filter visible so anyone can reproduce your sector choices.
What the IAB UK insight archive provides
The IAB UK insight archive collects UK digital advertising research, including creator and influencer formats. Use it for direction of travel and format mix, not for a precise England total.
IAB UK's annual digital adspend study has reported year-on-year growth in UK digital adspend in most recent years, and it publishes format splits.
Its value is comparability. When one source reports the same measure each year, you can describe change without inventing a growth rate.
Employment status changes who is in the market
A self-employed creator prices their own costs and profit. Someone engaged as a worker or employee has employer obligations attached, so their floor is different.
Which employment status applies?
Does the creator work for themselves?
self-employed: prices own costs and profit
worker or employee: employer obligations attached
Acas sets out how to work through those categories in its guidance on types of employment status. Get this wrong and your market rate averages two cost bases.
Split the groups, or state which one your benchmark covers. Commercial models decide who carries those costs, and sponsorship rates business models in England explains the common splits from flat fees to retainers.

Common questions
Is there an official sponsorship rates market size for England?
No. Official statistics cover business populations and economic activity rather than deal fees. Spend research comes from industry bodies and is usually UK-wide.
Why do UK totals keep appearing in England rate discussions?
Platforms and agencies report at UK level.
What is the quickest route to a defensible estimate?
Count the buyers you can verify, apply a labelled illustrative spend per buyer, and present a range.
Does employment status change the rate a creator should quote?
Yes. Self-employed creators price their own costs, while employment status adds employer obligations, so mixing the two distorts any average.
