Why agencies set a minimum ad spend, and what is fair

Key takeaways

Social media agency minimum ad spend exists because management takes similar time whatever the budget. A sensible UK paid social floor for a small business is about £300–£500 a month in media, and LinkedIn usually needs £1,000 a month or more. Below that, fees can outweigh spend.

• £300–£500 a month is a sensible paid social media floor for a small business.
• LinkedIn ads usually need £1,000 a month or more in media.
• Management takes similar hours on small and large budgets.
• Below the floor, organic content or boosting may be better value.

What is a minimum ad spend?

A minimum ad spend is the lowest monthly media budget an agency will manage. It is separate from the management fee. The media budget goes to Meta, LinkedIn or TikTok. The fee pays for the agency's time setting up, testing, optimising and reporting.

Why do agencies set a minimum?

Setting up campaigns, building audiences, testing creative and reporting take roughly the same hours whether you spend £200 or £2,000. On a very small budget, the management fee can be larger than the media, and there is too little data to learn what works. Minimums protect both sides from that.

What minimum is fair in the UK?

For Facebook and Instagram, a floor of about £300–£500 a month in media is a sensible minimum for a small UK business to test properly. LinkedIn ads cost more per click, so £1,000 a month or more is more realistic. These are indicative figures, not a GBL price list.

• Facebook and Instagram: about £300–£500 a month.
• LinkedIn: about £1,000 a month or more.
• TikTok: similar floor to Meta, plus regular video.
• Management fee: separate, typically £300–£1,000 a month.

What if your budget is below the minimum?

Below the floor, put the money into content and organic reach first, or boost your best-performing posts yourself with a clear audience. Once organic posts show which messages work, a small paid budget goes further. Some agencies also offer a lighter set-up and training option.

When is a high minimum a red flag?

A minimum well above what your market needs, or one that grows each month without results, deserves questions. Ask how the agency calculated it, what results similar businesses saw and how quickly you can reduce spend. A fair minimum is explained, not just stated.

What does this look like in practice?

A pattern we see with UK small businesses: a few hundred pounds a month is spread across several platforms, so no campaign gets enough data to improve. Global Bridge Labs (GBL) concentrates the budget on one platform and one offer until the numbers show it works, then expands.
