How much do Google Ads cost in the UK? What decides it, and what I've paid per result

The honest answer is that nobody publishes a reliable UK-wide figure, because Google doesn't. What exists is agency estimates built from Keyword Planner, auction insights and their own accounts. They're useful for a rough sense of scale, so here's what they say, followed by what actually decides your cost.

The published ranges

Two UK sources updated for 2026 put the cross-industry average cost per click at roughly £1.50 to £2.50 for most small businesses, with a wide spread by sector. Both give legal services the highest average at about £8.25 a click, financial services around £5.50, B2B software around £3.65, home services and trades £2.85 to £3.20, healthcare £2.80 to £4.10, education around £2.40, and ecommerce under £1.00 to around £1.50 depending on the category. Travel and hospitality sit around £1.25 to £1.60. One of the sources says plainly that no primary UK-wide survey of click costs exists and describes its figures as indicative, which is the right way to read them.

A click isn't a result, though. The number that matters is what you pay for a lead or a sale, and that depends on four things the averages can't see.

1. What you're asking Google to buy

The same account can be bought on clicks, on leads or on order value, and the cost per result changes completely depending on which.

For Boatastic, a yacht hire business in the UAE, a Performance Max campaign brought 724 clicks cheaply, with a 3.55% click-through rate. A rebuilt search campaign bidding to a target cost per lead had a 15.23% click-through rate and brought 111 enquiries at AED56.47 each. Same business, same month. The second campaign was asked for leads and priced on them. The Boatastic case study has both.

2. Whether the tracking is right

If Google can't see the sale, it optimises on something it can see, and you pay for that instead.

For Ginyaki, a restaurant group with an ordering app whose Google account I ran in 2023, the first Performance Max campaign bid on "conversions" and returned 1.25 in conversion value. A second one bid on Target ROAS using GA4 purchases with their real order values, and returned 4.27. The cost of the clicks didn't move much. What changed was that Google knew what an order was worth. The Ginyaki Google Ads case study covers it.

3. How tightly the campaign is built

A campaign with one ad group and forty keywords pays for a lot of searches that had nothing to do with the business. Grouping tightly, cutting wasted search terms every fortnight and keeping brand searches separate from generic ones is where most of the saving sits. On Boatastic, the campaign that worked had three ad groups, each with its own keywords and ads, and was bid on Target CPA. That structure, more than any bid change, is what brought the cost per lead down.

4. What a result is worth to you

A £20 lead is expensive for a takeaway and cheap for a solicitor. Before I set a budget I want to know what a customer is worth, roughly how many enquiries it takes to win one, and from that what a lead can cost before the campaign stops making sense. The budget follows that calculation, not the other way round.

What I've paid per result

For a sense of scale from accounts I've run, with the year, in the client's currency:

• Boatastic (UAE, yacht hire, search, 2025–26): 111 leads at AED56.47 each.
• Lit (Pakistan, fast food, Smart campaigns on Search and Maps, 2025): 585 direction requests and 70 calls, with the best branch campaign at Rs15.99 per action and 48.6% of clicks turning into a call or a direction request.
• Ginyaki (Pakistan, restaurant app, 2023): 1,284 installs at Rs22 each on the main app campaign.

None of these is a benchmark for your business. They're what happens when the campaign is asked for the right thing, the tracking is honest and the structure is tight.

What to budget

Google needs enough conversions to learn from, which in practice means a budget that can produce around 30 conversions a month on the campaign that matters. For a UK local service business that often means a four-figure monthly spend. Below that, a well-built campaign can still work, but it learns slowly and should be judged over months rather than weeks.

If you want a number for your own business rather than an industry average, send me read-only access to an existing account, or a description of what you sell and where. I'll tell you what I'd expect a lead to cost and what I'd change first.
