TL;DR: Google Ads can generate consistent, high-intent leads for UK tradespeople — but only if set up and managed correctly. The average cost per click for plumbing keywords is £5–£14, and a well-optimised campaign typically delivers leads at £25–£60 each. This guide covers everything: budgets, keywords, Local Services Ads, and the mistakes that silently drain your account.
If you want leads fast, Google Ads is the most direct route available to a trades business in 2026. Unlike SEO — which takes months to build momentum — a properly run Google Ads campaign can put your business in front of homeowners searching for a plumber, electrician or builder within hours of going live.
The catch? Done badly, it is one of the fastest ways to burn through your marketing budget with nothing to show for it. This guide covers every decision you need to make before spending a penny.
How Does Google Ads Actually Work for Trades Businesses?
When someone searches “emergency plumber Watford” or “electrician near me,” the businesses appearing at the top of the results — marked “Sponsored” — are there because they are running Google Ads.
You do not pay for your ad to show. You only pay when someone clicks on it. That is the pay-per-click model. You set a budget, choose the keywords you want to appear for, write your ads, and Google shows them to relevant searchers within your chosen area.
For trades, this works well because the searches are high-intent. Someone typing “boiler repair Hemel Hempstead” is not browsing — they have a problem and they need it fixed today. That is the kind of customer you want to reach.
A typical campaign for a plumber or electrician includes:
- A list of keywords (e.g. “plumber near me”, “emergency electrician”, “boiler service Luton”)
- A defined service area — usually a 10–20 mile radius around your base
- 2–3 ad variations tested against each other
- A daily or monthly budget cap so you never overspend
Local Services Ads vs Regular Google Ads: Which Should You Use?
This is the question that trips up more UK tradespeople than any other, so here is the short version.
Local Services Ads (LSAs) appear above regular Google Ads in search results. They show your business name, star rating, phone number, and a “Google Guaranteed” badge — and you only pay when a customer contacts you directly, not when they click. Leads through LSAs typically cost £20–£35 for plumbing and electrical work in the UK.
To run LSAs you need to pass Google’s verification process. That means providing proof of insurance, your Gas Safe or NICEIC registration, and relevant trade credentials. Once verified, the Google Guaranteed badge is a strong trust signal — especially for homeowners who have been burned by cowboy builders before.
Regular Google Ads appear just below LSAs. You pay per click, not per lead, and you have far more control over keywords, ad copy, and landing pages. For well-managed campaigns, cost per lead typically sits at £25–£60.
Which should you use? Ideally both. LSAs are worth setting up if your trade qualifies — the pay-per-lead model alone makes them excellent value. Regular Google Ads give you more control and can scale further as your budget grows.
If you are starting with a limited budget, set up regular Google Ads first. You will get more data, more control, and more flexibility from day one.
How Much Should UK Tradespeople Spend on Google Ads?
Here are real UK benchmarks for 2025 so you can set a realistic expectation before you commit.
Average cost per click by trade keyword:
- “Plumber” — £5–£14 per click
- “Emergency plumber near me” — £9.52–£22 per click
- “Electrician” — £2.49–£8.23 per click
Competition is 15–30% higher in London compared to cities like Sheffield, Leeds or Bristol. If you are based in the capital, your budget needs to stretch further to generate the same number of leads.
Recommended monthly ad spend budgets:
- Solo trader, one local area: £500–£750/month
- Small team covering a wider radius: £750–£1,500/month
- Multiple service areas or trades: £1,500–£2,500/month
Google’s algorithm needs roughly two to three months of data to optimise properly. In that initial learning phase, your cost per lead will be higher than it will be once the campaign is established. Budget to run consistently for at least three months before drawing firm conclusions.
At £8 per click with a 15% landing page conversion rate, you are paying roughly £53 per lead. If your average job is worth £400–£600, that is a strong return. If your jobs average £150, you need to tighten your targeting or improve your landing page.
What Keywords Should Tradespeople Bid On?
Most tradespeople bid on keywords that are too broad, then wonder why they are getting clicks from people searching “how to become a plumber” or “plumbing courses near me.”
Start with high-intent, location-specific searches:
- “[Trade] near me” — e.g. “boiler repair near me”
- “[Trade] [town]” — e.g. “electrician Milton Keynes”
- “Emergency [trade]” — e.g. “emergency plumber”
- “[Problem] [area]” — e.g. “blocked drain Hertfordshire”, “fuse board replacement St Albans”
Use phrase match or exact match for all of these — not broad match. Broad match will show your ad for anything loosely related to your keywords, which means irrelevant clicks and wasted money.
Add negative keywords from day one. These are terms you explicitly do not want to appear for. A plumber’s negative keyword list should include: “diy”, “course”, “training”, “apprenticeship”, “salary”, “parts”, “how to”, “cheap”. A roofer’s should include: “roofing jobs”, “tiles uk”, “history of roofing”. Ignoring negative keywords is the single biggest reason UK trades businesses waste their Google Ads budget.
The Google Ads Mistakes That Cost Tradespeople the Most Money
A roofing company told us they had spent £900 a month on Google Ads for six months and “hadn’t really got much from it.” When we looked at the account, 30% of the budget — around £270 a month — was going on clicks entirely unrelated to roofing jobs. That is over £1,600 wasted in six months, simply because nobody had checked the settings.
The most common mistakes:
- Broad match keywords — your ads show for anything vaguely related, not just buying-intent searches
- No location control — campaigns running UK-wide when you only work within a 15-mile radius
- Sending traffic to your homepage — your homepage is not built to convert an ad click. You need a focused landing page with a clear phone number and a simple enquiry form
- Set and forget — Google Ads needs monthly attention: check your search terms report, add negative keywords, pause underperforming ads, test new copy
- No conversion tracking — if you do not know which keywords are generating calls and enquiries, you cannot make good decisions. Set up call tracking before you spend a penny

How to Know If Your Google Ads Are Actually Working
The question to answer is not “am I getting clicks?” — it is “am I getting leads, and what are they costing me?”
Set up this tracking before you run a single ad:
- Call tracking — use a unique phone number that records calls coming from your ads. Services like WhatConverts or ResponseTap start from around £30–£50 per month
- Form tracking — set up a conversion in Google Ads that fires when someone submits your contact form
- Google Analytics — connect your website and Ads account so you can see the full picture
Once you have tracking in place, the numbers become clear. Most well-run accounts for UK trades businesses achieve a cost per lead of £25–£60 within three to four months.
Compare that to Checkatrade, where annual membership starts at around £600–£1,200 and the leads are shared with multiple other tradespeople bidding against you. Or Rated People, where you pay per quote with no guarantee of winning the job. With your own Google Ads account, you own the lead — no auction, no competition, no one undercutting you on the platform.
