A sustainable IFA marketing budget is typically 10-20% of gross new-client revenue, starting from a minimum viable test spend of £3k-£5k per month for paid acquisition.
As a rule of thumb, a UK IFA should plan paid marketing spend at 10-20% of gross new-client revenue. Below £3k/month, paid social rarely has enough volume to generate reliable learnings for the ad platforms. Established firms running structured acquisition spend £8k-£40k/month across Meta, Google and LinkedIn. Budget should be allocated in a 60/30/10 split across acquisition, retargeting and creative testing until measurement is robust.
