Google Ads for Local Services: Budgets, Match Types and Negative Keywords Explained
If you run a local service business in London or anywhere else in the UK, Google Ads for local services can put you in front of customers at the exact moment they're searching for what you offer. But without the right budget, keyword match types and negative keywords in place, that same campaign can quietly burn through your marketing spend on clicks that were never going to become customers. This guide walks through how each of those three pieces fits together, drawing on Google's own guidance, so you can set up - or fix - a Google Ads account that works for a local service business rather than against it.
What Makes Google Ads for Local Services Different
Someone searching "emergency plumber near me" or "boiler repair tonight" has already decided they need help - they just haven't decided who from yet. That's a very different kind of intent to someone researching "how boilers work", and it's why search ads tend to suit local service businesses so well: you're not trying to create demand, you're capturing it at the exact moment it exists. Google Ads for local services tends to work best alongside organic SEO rather than instead of it - paid search can get you visible today while your SEO work builds rankings that keep paying off for months or years. If you haven't already thought through how the differences between the two line up with your budget and timeline is worth reading before you set anything live.
How Much Budget Do You Actually Need?
Google Ads campaigns run on an average daily budget rather than a fixed daily spending cap, and the mechanics catch a lot of advertisers out. According to Google's own help documentation, a campaign can spend up to twice your average daily budget on any single day, but your total charges for the month will never add up to more than 30.4 times your average daily budget - 30.4 being the average number of days in a calendar month.
In practice, that means if you want to spend around £600 a month on Google Ads for local services, you'd set an average daily budget of roughly £20 (£600 divided by 30.4), and you should expect some days to cost £40 or more while others cost far less, as Google shifts spend towards the days when more of your customers are actually searching. Swings like this are normal and aren't a sign that anything is broken. What's worth checking every few weeks is your actual monthly total in the billing summary, to make sure it's tracking to the figure you planned for rather than drifting upwards.
Match Types Explained: Broad, Phrase and Exact
Every keyword you add to a Google Ads account uses one of three match types, and the match type decides how closely a search has to resemble your keyword before your ad is allowed to show for it.
Broad match (no punctuation, e.g. boiler repair) is the default for every keyword you add. Your ad can show for searches Google judges to be related to the keyword's meaning, which can include synonyms and related phrasing, and Google says this can also take into account your other keywords, your landing page and the searcher's recent activity. It's the widest net of the three, and Google recommends pairing it with Smart Bidding.
Phrase match (in quotation marks, e.g. "boiler repair") shows your ad on searches that include the meaning of your keyword, including more specific versions of it. It reaches more searches than exact match but fewer than broad match.
Exact match (in square brackets, e.g. [boiler repair]) shows your ad only on searches with the same meaning or intent as your keyword. It gives you the most control over who sees your ad, but reaches the fewest searches of the three.
One detail that catches people out: each match type nests inside the next. A phrase keyword matches everything an exact keyword would, plus more; a broad keyword matches everything a phrase and exact keyword would, plus more again. There's no version of "exact match, but even narrower" available beyond what exact match already restricts you to.
Picking the Right Match Type for Google Ads for Local Services
For a local service business working with a modest monthly budget, starting narrower usually makes sense. Phrase and exact match let you control which searches actually trigger your ad, so your early spend goes on the handful of terms you already know describe what you do - "boiler repair [your town]", "emergency plumber [your town]" and similar - rather than being spent finding that out the expensive way. As your account builds up conversion data, broad match paired with Smart Bidding, as Google suggests, can be worth testing within the same campaign, since the algorithm then has real performance signals to bid against instead of guessing. What rarely works well is broad match combined with manual bidding and no conversion tracking in place - that combination tends to spend a local service budget on searches with only a loose connection to what you actually offer.
Building a Negative Keyword List That Protects Your Budget
Negative keywords stop your ad showing for searches you don't want to pay for, and they follow the same three-way logic as ordinary keywords:
Negative broad match (the default) blocks your ad whenever a search contains all of the negative terms, in any order. Adding "repair" as a negative broad keyword blocks both "repair courses" and "courses on repair".
Negative phrase match blocks your ad only when the negative terms appear together, in that order, with other words allowed around them.
Negative exact match blocks your ad only when the search matches the negative term exactly, with nothing extra added.
Google's own guidance points out something easy to miss: negative keywords don't automatically cover close variants the way ordinary keywords do, so you'll often need to add the plural, a common misspelling or a synonym separately to close the same gap. For a local service business, a short starting list usually catches a good amount of wasted spend: "jobs", "careers", "course", "training", "DIY", "how to", "free", competitors' brand names, and any town or area outside where you actually work. It's also worth setting up an account-level negative keyword list, since it applies automatically across your eligible Search campaigns rather than needing to be added to each one by hand.
A Simple Campaign Structure for Google Ads for Local Services
Google's own advice on account structure is to give each ad group a narrow theme and fill it only with keywords tied to that theme, often mirroring the structure of your own website, with at least three ads running in each group so Google's ad rotation has something to test between. For a local service business, that usually means one ad group per service - boiler repair, bathroom installation, emergency callouts - rather than one large ad group covering everything you do. Google also warns that reorganising an account after it's built up performance history can lose that history, so it's worth getting the structure roughly right from the start rather than rebuilding it every few months.

Getting Help with Google Ads for Local Services
Google Ads for local services rarely works best in isolation. The businesses that get the strongest return tend to be running paid search alongside solid local SEO foundations and keeping an eye on both sets of results in the same place, rather than treating them as separate budgets competing for attention. If you're not sure whether your current budget, match types or negative keyword list are doing their job, a second pair of eyes usually finds the leaks quickly.
