Small Business Marketing Budget: How Much Should You Spend? (UK Guide 2026)

It's one of the most common questions I hear from business owners: how much should I actually be spending on marketing? The honest answer is that there's no single figure that fits everyone, but there are clear benchmarks you can use to set a sensible budget. Here's how to think about it without overspending or starving your growth.

The simple benchmark: a percentage of revenue

Most guidance lands in a similar range. Established businesses tend to spend around 5 to 10% of revenue on marketing, while businesses in a growth phase, or in competitive markets, often push toward 10 to 15%. If you're turning over £200,000 a year, that's roughly £10,000 to £30,000 annually, or about £830 to £2,500 a month. Newer businesses trying to build awareness usually sit at the higher end, because they're starting from scratch and need to buy visibility they haven't earned organically yet.

Why the percentage isn't the whole story

A percentage gives you a starting point, not an answer. What matters far more is what you spend it on and whether it's being tracked. I've seen businesses spend £500 a month and generate a steady flow of enquiries, and others spend £5,000 a month with almost nothing to show for it. The difference is rarely the budget itself. It's strategy, targeting, and whether the website actually converts the traffic once it arrives.

Splitting the budget: ads, SEO and your website

A practical way to divide a marketing budget is across three areas that support each other. Paid ads on Meta and Google buy you visibility quickly, which is useful when you need enquiries this month. SEO is slower but compounds, building rankings and traffic you don't have to keep paying for. And your website ties it all together, because every pound spent driving traffic is wasted if the page doesn't turn visitors into enquiries. A common mistake is pouring everything into ads while ignoring the website, which is like turning on a tap with no bucket underneath.

What your small business marketing budget gets you

At £300 to £500 a month, you can run a focused campaign on a single channel, usually Meta or Google ads, aimed at one clear offer. At £1,000 to £2,000 a month, you can realistically combine paid ads with ongoing SEO and regular website improvements. Above £3,000 a month, you can run multiple channels properly, test more, and scale what works. The key at every level is consistency. Marketing rewards businesses that treat it as an ongoing system, not a one-off push. Whatever the figure, the right small business marketing budget is simply one you can sustain and measure.

How to avoid wasting your budget

The fastest way to waste money is to spend without tracking. Before increasing any budget, make sure you can answer three questions: where are enquiries coming from, what does a lead cost you, and what is a customer worth? Get proper tracking in place, fix the obvious friction on your website, and start with a budget you can sustain for at least three months. Marketing that stops and starts rarely gets the chance to work.

The bottom line

As a rough rule, budget 5 to 10% of revenue if you're maintaining, and 10 to 15% if you're actively trying to grow. But treat that as a starting point, not a target. A smaller budget spent well, with clear tracking and a website that converts, will almost always beat a larger budget spent carelessly.
