How much does Google Ads cost for a small business in the UK?

There's no fixed price for Google Ads. You set your own budget, and what you pay for each click depends on how many businesses are bidding for the same searches, how relevant your ads are and where your customers are. For most small businesses there are two costs to plan for: the ad spend you pay Google, and a management fee if someone runs the account for you, which with us starts at £600 a month + VAT.

That isn't a very satisfying answer when you're trying to set a budget, so let's go through what actually drives the cost, how Google bills you and how to work out a starting figure that makes sense for your business.

How does Google decide what you pay?

Every time someone searches, Google runs an auction to decide which ads appear and in what order. You don't pay to appear. You pay when someone clicks, and the price of that click isn't set by your budget alone.

Google's own guide to costs, updated in 2026, says there's "no fixed price tag" and explains that relevance matters as much as money. Your Quality Score reflects how likely people are to click your ad, how closely the ad matches the search and how useful your landing page is. Google says relevant ads and helpful landing pages may even lower the price you pay per click.

For a small business, that's good news. A local firm with a sharp ad and a clear page can often hold its own against bigger competitors with bigger budgets, because Google is trying to show searchers the most useful result, not simply the highest bidder.

Why do clicks cost more for some businesses than others?

A few things push the price up. The first is competition. Google's guide notes that areas with higher demand or a denser concentration of competitors generally cost more, so a click in a big city can cost more than the same click in a small town.

The second is intent. Searches from people ready to buy, like "emergency electrician near me", attract more bidders than searches from people just looking for information, so they cost more. That's usually money well spent, because those are the people who pick up the phone.

The third is timing. Demand moves with the seasons. A heating engineer sees searches jump when the weather turns cold, a wedding venue sees enquiries pick up after Christmas, and click prices tend to follow the demand.

Finally, the state of your own account plays its part. Loose keywords, ads that don't match what people searched for and a slow or vague landing page all mean you pay more for every enquiry you get.

How does Google bill you?

You set an average daily budget, and Google works to it over the month. On busy days, your campaign can spend more than that figure. Google's help centre, checked in October 2026, says a campaign "might spend up to twice your average daily budget" on a given day to catch peaks in traffic, but over a month you won't be charged more than 30.4 times your daily budget, which is the average number of days in a month.

So if you set £20 a day, some days will cost more and some less, but as long as you don't change the daily budget mid-month, your bill for that campaign won't go over £608. That makes Google Ads easier to plan for than it first looks.

What does it cost to have someone manage it?

You can run Google Ads yourself, and some business owners do. The trouble is time. A well-run account needs new negative keywords every week, ads tested against each other, bids adjusted and tracking checked, and that's hard to fit around a full diary.

If you hand it to an agency, you'll pay a management fee on top of your ad spend. Ours starts at £600 a month + VAT on the Starter plan, which covers up to £2,000 a month in ad spend, with Growth at £1,000 and Scale at £1,800 a month for bigger accounts. Your ad spend is paid directly to Google, so you can always see exactly what's going on clicks. Every plan has a 6-month minimum term, and our Google Ads page sets out what's in each one.

Whoever you choose, ask how they'll track enquiries. A report full of clicks and impressions tells you very little. What you need to know is how many calls and forms came in, from which searches, and what each one cost.

How much should a small business spend on ads?

Start with what a customer is worth to you, not with a round number. Say a typical job brings you £450 of profit and you win one in every three enquiries. You could pay up to £150 for an enquiry and still break even on the first job, before you count repeat work or referrals. If you want ten more enquiries a month, that gives you a ceiling to work back from.

Those figures are only an example, but the method works for any business. Next, look at your market. If clicks in your area and trade are expensive, you'll need more budget to gather enough data to learn from. In a quieter market, you can start smaller.

A good starting budget is one you can keep running for a few months. Campaigns improve as they learn which searches, ads and areas bring in work, and switching off after three weeks usually means paying for the learning without getting the benefit. It's why our free audit suggests a starting budget after looking at who's bidding in your area, rather than picking a number off the shelf.

What does a good result look like?

It depends on the business, but a good campaign is one that turns into work you can count. For Caltech Lifts, a stairlift company that wanted more private customers, our campaign brought in 35 qualified leads and 15 completed sales, a 43% lead-to-sale rate, and built a sales pipeline of up to £120,000. Those numbers came from a campaign focused on the right searches, with every enquiry tracked back to the ad that produced it.

For trades, the detail matters even more. Our page on Google Ads for heating engineers shows how one budget can be split between winter breakdowns and summer servicing, and our page on Google Ads in Edinburgh explains how we handle a busier city auction.

Is Google Ads worth it for a small business?

For most service businesses, yes, as long as the campaign is focused and tracked. People searching on Google are usually looking for help right now, which is very different from someone idly scrolling past an ad. When your ad answers their search and your page makes it easy to get in touch, you're paying to be in front of people who already want what you do.

If you'd rather not run ads on their own, the DLR Growth Engine combines Google Ads with Meta Ads, SEO, GEO and a free custom website for £1,499 a month + VAT on a 12-month term.

Frequently asked questions

Is there a minimum spend on Google Ads?

No. You choose your own daily budget. What matters is spending enough to get useful data on which searches bring in enquiries.

Can Google spend more than my daily budget?

Yes, on individual days. A campaign can spend up to twice its average daily budget on a busy day, but you won't be charged more than 30.4 times that daily budget over a month.

How quickly will Google Ads bring in enquiries?

With us, campaigns go live in 5 days on average after onboarding, and most clients see enquiries within the first 2 weeks.

Do I pay the ad spend to you or to Google?

You pay it straight to Google. Our management fee is separate, so you always know what's going on clicks and what's going on management.
