How Much Should a UK Business Spend on Marketing in 2026?
Most UK businesses should spend between 5 and 15 percent of revenue on marketing, and where you land inside that range depends on your size and stage, not a single rule. Established businesses with steady revenue tend to sit at the lower end, around 5 to 10 percent. Newer or fast-growing businesses, and smaller SMEs under £10M, often need 10 to 16 percent or more to compete, because fixed costs are a bigger share of a smaller turnover. The number matters less than the structure behind it.
"How much should I spend on marketing?" is one of the most common questions a business owner asks, and one of the worst-answered. Most advice online is either recycled from 2018 or so vague it's useless. The honest answer has two parts: a sensible range to anchor on, and the real factors that decide where inside that range you belong.
This guide gives you both. Real UK benchmarks by size and stage, the reasons smaller businesses need proportionally more, and the one question that matters more than the percentage. By the end you'll have a number you can actually defend, and a way to sanity-check it against what your marketing is doing.
The short answer, and why it isn't the whole answer
The widely cited benchmark for established UK businesses is 7 to 10 percent of annual revenue. That's a fine starting point, and it's the figure most accountants will recognise. But it hides more than it reveals, because it only really applies to one type of business: one with stable revenue and existing brand awareness.
The fuller picture, drawn from a mix of Gartner, Deloitte and ONS-based analysis, looks like this. Across all industries the average sits around 7.7 percent, though that number is skewed by large enterprises. The practical range for most UK businesses runs from about 5 percent at the very established, maintain-what-you-have end, up to 15 to 20 percent for newer brands or those pushing hard for growth in a competitive space.
So the real answer is a range, not a number, and your job is to work out where inside it you sit. That depends on three things: your size, your stage, and your goals.
Why smaller businesses need to spend proportionally more
This is the part that surprises owners, and it's important. Smaller businesses generally need a higher percentage of revenue than larger ones, not a lower one.
The reason is fixed costs. A lot of marketing spend is fixed regardless of business size: a website, the tools, content production, the basic infrastructure of being visible. For a business turning over £10M, those fixed costs are a rounding error as a percentage. For a business turning over £400k, the exact same costs eat a much larger slice of revenue. So the smaller business has to spend a higher percentage just to reach the same baseline of visibility.
The numbers bear this out. According to analysis of UK SME marketing spend, businesses under £10M in revenue often need to invest around 16.8 percent to compete effectively, well above the 7.7 percent all-industry average that gets quoted everywhere. Businesses under £500k in particular tend to need the higher end, roughly 10 to 15 percent, for exactly this fixed-cost reason.
Larger competitors can spread their costs across a bigger revenue base. Smaller businesses can't, so if you're an SME benchmarking yourself against the 7 to 8 percent figure you read somewhere, you may be underspending your way out of the market without realising it.
The three lenses for setting your budget
A percentage of revenue is a useful anchor, but on its own it's blunt. The better approach blends three lenses, and checking all three keeps you from setting a number that looks sensible on a spreadsheet and fails in reality.
Lens one: percentage of revenue
Start here for a sanity-check figure. Use the range that matches your stage: 5 to 10 percent if you're established and maintaining, 10 to 20 percent if you're newer, growing fast, or in a competitive space. This gives you a number in the right ballpark before you refine it.
Lens two: goals
Now ask what you actually need the budget to do. A percentage of revenue tells you what's typical. It doesn't tell you what your specific target requires. If you want to add 50 new customers a quarter and you know roughly what a customer costs to acquire, you can work backwards to the spend that goal demands. Sometimes that number is higher than your percentage suggests, sometimes lower. The goal-based figure is the reality check on the percentage.
Lens three: unit economics
Finally, sanity-check both against the maths of a single customer. If your average first-year value per new customer is £2,000 at a 50 percent gross margin, spending £500 to acquire one may be sensible. Spending £1,200 is not. Your unit economics set the ceiling on what a customer can cost you, and no budget percentage should push you past it. This is the lens that stops you scaling spend into unprofitable territory just because the percentage "allowed" it.
Blend the three. The percentage anchors you, the goal tells you what's required, and the unit economics keep you honest. A number that survives all three is a number you can defend.
What the range looks like in actual pounds
Percentages are easy to nod along to and hard to act on. Here's what the range means in real money at different revenue levels, so you can see roughly where your own number should land.
Take a business turning over £250,000 a year. At the established end of 7 percent, that's about £17,500 a year, or roughly £1,460 a month. If that business is newer or pushing for growth and sits nearer 12 percent, it's £30,000 a year, or £2,500 a month. Same business, very different budget, depending purely on stage.
Now a business at £1M revenue. Seven percent is £70,000 a year, about £5,800 a month. Ten percent is £100,000, or a little over £8,300 a month. A £2M business at 8 percent is £160,000 a year, roughly £13,300 a month.
And at the smaller end, where the fixed-cost problem bites hardest: a £120,000 business may genuinely need 15 percent, which is £18,000 a year or £1,500 a month, just to reach a workable baseline of visibility. Notice that the £120k business and the £250k business can end up spending a similar amount in pounds, because the smaller one needs a higher percentage. That's the fixed-cost effect in practice.
The point of running your own numbers this way is that it moves the decision from a vague percentage to a concrete monthly figure you can plan around, staff around, and hold your marketing accountable to. A percentage is a starting point. A monthly pound figure is something you can actually manage.
Established, growing, or brand new: pick your row
Where you sit in the range comes down mostly to stage. Here's the rough guide.
If you're an established business with steady revenue, existing customers, and a recognised name in your market, you're at the lower end. Around 5 to 10 percent of revenue keeps you visible and competitive without overspending on awareness you already have. Your marketing is defending and extending a position, not building one from scratch.
If you're a growing business with a defined offer that's working and a real appetite to scale, you're in the middle to upper part, roughly 7 to 15 percent. You need enough budget to build brand, test channels, and push into new demand, not just maintain what you have.
If you're a new or early-stage business, or you're entering a competitive space where nobody knows you yet, you're at the top of the range, 10 to 20 percent, sometimes higher for a period. Everything is being built for the first time: awareness, trust, a customer base. That costs proportionally more, and underspending here is one of the most common reasons new businesses stall before they get traction.
The mistake is picking a percentage once and freezing it. Your right number moves as you move between these stages, and reviewing it at least once a year keeps you from either starving growth or wasting money on awareness you no longer need to buy.
The question that matters more than the percentage
Here's the thing almost every "how much should I spend" guide misses. The amount matters far less than the structure behind it.
A £50k budget with clear tracking, defined channels and a monthly review will outperform a £150k budget scattered across whatever felt right last quarter. Most UK businesses fall into one of two traps: they either spend too little to make a difference, or they spend plenty without knowing what it's doing. Both problems have the same root cause, which is no structure behind the number.
So before you agonise over whether you should be at 8 percent or 12 percent, ask a better question. What is my marketing actually doing, specifically, to generate revenue? If you can't answer that, the percentage is beside the point. A smaller, well-structured budget with proper tracking will beat a larger, unstructured one almost every time.
This is also where a lot of spend leaks without anyone noticing. You can be spending a perfectly sensible percentage and still waste half of it, because the leads the budget generates never get followed up, or the tracking is broken so you can't tell what's working. We cover that in why your Google Ads get clicks but no customers and the real cost of a lead you never follow up. Getting the number right is only half the job. Spending it well is the other half.
How this maps to what an agency should charge you
One practical use of all this: it tells you whether an agency's pricing is sensible for your business.
If a marketing budget of more than 15 percent of your revenue is a stretch, and an agency is pushing you toward a spend level well above that, something is off, either with the recommendation or with their incentive to make it. A results-focused agency should be sizing your plan to your revenue, not to what they'd like to sell you. At IC Leads we build the range straight into how we work: we tell you plainly when your spend is too low to hit your goal, or higher than your revenue can comfortably support. See how much of that budget should sit on which platform.
The tell is simple. An agency paid on a percentage of your spend has a reason to grow your budget whether or not it works. An agency on a flat fee doesn't. Worth knowing which one you're talking to before you take their number on how much you should spend.
Common budgeting mistakes
A few patterns to avoid.
Benchmarking against the wrong figure. The 7.7 percent all-industry average is skewed by large enterprises. If you're a sub-£10M SME, your realistic range is higher, and comparing yourself to the enterprise number leads you to underspend.
Setting the number and never revisiting it. Your right percentage changes as you grow. A fast-growth phase justifies a higher number than a steady-state one, and freezing the budget at last year's percentage can starve growth or waste money depending on which way things moved.
Spending without structure. A budget with no tracking, no defined channels and no monthly review will underperform a smaller one that has all three, every time.
Cutting marketing in a downturn. Businesses that maintain or increase spend through a downturn consistently outperform those that cut, because share is cheaper to win when competitors go quiet.
Ignoring unit economics. If a customer is worth £2,000 to you, there's a hard ceiling on what one can cost to acquire, and no percentage rule overrides that maths.
The honest version
There's no single right number, and anyone who gives you one without asking about your size, stage and goals is guessing. The honest range for most UK businesses is 5 to 15 percent of revenue, higher for smaller SMEs and fast-growth phases, lower for established, steady businesses. Where you land is a blend of the percentage, your goals, and your unit economics.
But the number is the easy part. The businesses that win aren't the ones that found the perfect percentage. They're the ones that spend whatever they spend with structure behind it: clear tracking, defined channels, and a machine that actually converts the leads the budget produces. Get that right and a modest budget beats a bloated one. That's the whole idea behind how the IC Leads model works, and it's why we'd rather help you spend a sensible number well than a big number badly.
People also ask
Most UK small businesses should spend between 5 and 15 percent of revenue, depending on stage. Established businesses with steady revenue tend to sit at 5 to 10 percent, while newer or fast-growing businesses often need 10 to 20 percent. Smaller SMEs under £10M frequently need the higher end, up to around 16.8 percent, because fixed marketing costs take a larger share of a smaller turnover.
Because a lot of marketing cost is fixed regardless of business size. A website, tools and content production cost roughly the same whether you turn over £400k or £10M, so for the smaller business they eat a much larger share of revenue. A larger competitor spreads those fixed costs across a bigger base, which is why SMEs often need a higher percentage just to reach the same baseline of visibility.
Spend it better, almost always. A smaller budget with clear tracking, defined channels and a monthly review will usually outperform a larger budget scattered without structure. Most businesses either underspend or overspend without knowing what the money is doing. Fixing the structure, especially the follow-up that converts leads, often does more than adding budget.
Check whether they're sizing your spend to your business or to their own revenue. An agency paid a percentage of your ad spend earns more when you spend more, whether or not it works, so it has a reason to push your budget up. A flat-fee agency doesn't. If you're being pushed well above 15 percent of your revenue without a clear reason tied to your goals, question the recommendation and the incentive behind it.
