Plenty of UK service businesses start out managing their own Google Ads account, and there's nothing wrong with that early on. But there's usually a point where doing it yourself starts costing more, in wasted spend and missed jobs, than paying someone to do it properly. Here are the signs worth watching for.

1. You're not sure what's actually working

If you couldn't say which keywords, ads, or campaigns are actually bringing in paying customers, as opposed to just clicks, that's the clearest sign your account is missing proper conversion tracking, and by extension, that nobody's really steering it.

2. Your cost per lead keeps creeping up

Google Ads accounts left unmanaged tend to get more expensive over time, not less. Without regular pruning of underperforming keywords, adding negative keywords, and refreshing ad copy, you end up paying more for the same, or fewer, leads month after month.

3. You're getting leads, but they're the wrong ones

Plenty of enquiries but few actually turn into booked jobs? That's usually a targeting problem: broad match keywords, the wrong locations, or ad copy that doesn't filter out people who were never going to be a good fit in the first place.

4. You don't have time to check it regularly

Google Ads isn't a "set it up once and forget it" system. It needs regular attention to stay efficient. If you're running a business and only glancing at your account once a month, or less, it's very likely losing money quietly in the gaps.

5. You've never tested different ads or landing pages

The businesses that get the most out of Google Ads are constantly testing: different headlines, different offers, different landing pages, to see what actually converts best. If your ads and landing page have looked the same since day one, there's almost certainly performance being left on the table.

6. Leads come in, but nobody follows up fast enough

This one isn't really an ads problem at all, it's a systems problem. Studies on lead response time consistently show that the odds of converting a lead drop sharply the longer you wait to contact them. If leads are sitting in an inbox for hours before anyone replies, you're paying for clicks you're not capitalising on.

7. You're competing against businesses with dedicated marketing support

If your competitors are running polished, well-tested campaigns backed by an agency or in-house marketer, a self-managed account is starting from behind. Not because your business is worse, but because theirs has more consistent attention behind it.

What hiring the right agency actually changes

A good agency isn't just "someone else clicking the buttons". It's ongoing keyword and negative keyword management, conversion tracking that actually tells you what's working, regular ad and landing page testing, and a system for making sure every lead gets followed up quickly. That combination is what turns ad spend into booked jobs rather than just clicks.

At LeadCrafters, every campaign includes a CRM that lets you view, manage, accept and reject every lead as it lands, so the follow-up side is covered too, not just the ads.

Final thoughts

None of these signs on their own mean you have to hire an agency. But if two or three sound familiar, it's worth at least getting a second opinion on your account before more budget goes out the door.

"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.
