"How much does Google Ads cost?" is one of the most common questions we get asked by UK service businesses, and it's a fair one, because the honest answer is "it depends." Unlike a fixed-price product, Google Ads runs on an auction, so your cost is shaped by your industry, your location, your competitors, and how well your account is actually set up.

This guide breaks down exactly what you're paying for, what's typical for UK trade and service businesses in 2026, and how to avoid the hidden costs that quietly drain a budget.

The two costs you're actually paying for

Every Google Ads campaign has two separate costs, and mixing them up is where a lot of confusion starts:

• Ad spend — the money paid directly to Google every time someone clicks your ad. This goes straight to Google, not to whoever manages your account.
• Management fee — what you pay an agency or freelancer (or the time cost of managing it yourself) to research keywords, write ads, build landing pages, and optimise the campaign over time.

A cheap management fee with a badly built campaign almost always costs more in wasted ad spend than a slightly higher fee attached to an account that's actually optimised. The management side is where the real value, or the real waste, happens.

Average Google Ads costs for UK service businesses

Cost-per-click (CPC) varies hugely by trade. As a rough guide for 2026:

• Home services (plumbers, electricians, roofers, garage doors, landscaping) typically see CPCs from around £2 to £8.
• Higher-ticket trades (boiler installation, driveways, extensions, solar) often sit in the £5 to £15 range, since the lifetime value of a customer is much higher.
• Professional services (solicitors, accountants, financial advisers) can see CPCs well above £15 to £20 in competitive areas.

These are general ranges, not guarantees. Your actual CPC depends on how many competitors are bidding in your area and how relevant Google judges your ads and landing page to be.

How much should you budget to see real results?

As a starting point, most local service businesses need at least £500 to £1,000 a month in ad spend to gather enough data for the campaign to start optimising properly, with £1,000 to £2,000 and above being a more realistic range for businesses wanting a steady, predictable flow of leads rather than a trickle.

Spending too little is one of the most common reasons Google Ads "doesn't work" for a business. The campaign never gets enough clicks and conversions to learn who your best customers actually are.

Management fees: percentage vs flat fee

Agencies typically charge one of two ways:

• Percentage of ad spend — usually 10 to 20 per cent. The downside is the agency's incentive is for you to spend more, whether or not that spend is actually needed.
• Flat monthly fee — a fixed price regardless of ad spend. This removes the conflict of interest entirely, since the agency isn't paid more for pushing your budget up.

Hidden costs that catch businesses out

The sticker price is rarely the full story. The costs that actually sink a Google Ads budget are usually:

• No conversion tracking — without it, neither you nor Google's algorithm can tell which clicks actually turned into paying customers, so the campaign can never truly optimise.
• Broad match with no negative keywords — ads showing for irrelevant searches, burning through budget on clicks that were never going to convert.
• Slow or unclear landing pages — paying for a click only to lose the visitor because the page took too long to load or didn't make it obvious what to do next.
• No lead follow-up system — the ad spend did its job and generated the enquiry, but the lead went cold because nobody followed up quickly enough.

This last one is exactly why we build every LeadCrafters campaign with a CRM that feeds lead outcomes back into Google Ads. The better the follow-up, the better the algorithm gets at finding you more of the same.

What LeadCrafters charges

We keep our pricing simple and transparent: a one-off £400 setup fee and a flat £250 a month for ongoing management. No percentage-of-spend fee, and no incentive on our end to push your budget higher than it needs to be. Your ad spend is paid directly to Google, so there's never a markup hiding in the middle.

That includes campaign setup, keyword research, ad creation, a CRM to manage every lead that comes in, and a dedicated account manager watching performance week to week.

Final thoughts

Google Ads cost is really two decisions in one: how much you spend with Google, and how well that spend is managed. Get both right and it becomes one of the most predictable ways to generate new customers. Get either wrong and it's easy to burn through a budget with little to show for it.
