TL;DR: Google Ads can work for one-person trades businesses if you average £300+ per job and can commit £750–£1,500/month for 2–3 months while campaigns learn. Expect £20–£80 per lead in the UK. Below £500/month budget, most sole traders see poor returns because you can’t gather enough data to optimise. Local Services Ads may be a better starting point for emergency call-out work.
You’ve been thinking about Google Ads. Everyone says you should be doing it. But you’re a one-man band. Maybe you’ve got one lad helping out. You’re still on the tools most days. And the question keeps nagging at you: will it actually be worth the money?
Fair question. The honest answer is: it depends — mainly on your average job value, how quickly you answer the phone, and whether you can afford to test it properly.
What Google Ads Actually Cost for Trades
Here’s what you need to know upfront: Google Ads cost money before they make you money.
In the UK, a single click on “emergency plumber London” or “electrician near me” costs anywhere from £3 to £15. Sometimes more in busy areas. You might need 10–20 clicks before someone rings you. That’s £30–£300 just to generate one enquiry. And not every enquiry turns into a job.
Current UK data for 2026 shows:
- Cost per click: £3–£15 depending on your trade and location
- Cost per lead: £20–£80 for a phone call or form submission
- Monthly budget needed: £750–£1,500 minimum to gather enough data
- Time to see results: 2–3 months while Google learns what works
For context, plumbing leads average £133 per lead on Google Ads UK-wide, but that’s skewed by London. A Sheffield plumber targeting specific postcodes might pay £35. An electrician in rural Cornwall could be down at £22.
The big mistake is starting with £10/day (£300/month). At that level, you get maybe 2–3 clicks per day in competitive markets. That’s not enough data for Google to optimise. You’re basically throwing £300 away to learn nothing.
When It Works for Solo Traders
Google Ads makes sense if you tick these boxes:
1. Your average job value is £300 or more
If you’re charging £100 for a call-out and that’s it, the maths doesn’t work. You can’t pay £60 for a lead, convert 1 in 3, and make a profit on a £100 job.
But if your average job is £400–£600 (boiler service, full rewire, bathroom refit), the economics shift. A £60 lead turns into £200+ profit even at lower conversion rates.
2. You answer the phone fast
Google ranks Local Services Ads (more on those shortly) by response time. For regular Google Ads, if you’re not answering within 5 minutes, that lead is ringing three other people. Trades customers don’t leave voicemails and wait. They move down the list.
One plumber in Bristol told us he increased his Google Ads conversion rate from 22% to 41% just by putting his phone on loud and picking up faster.
3. You’ve got £750–£1,500 spare per month for 8–12 weeks
This is the hard truth. Google Ads need time to learn. The algorithm tests different audiences, refines who sees your ad, works out what time of day converts best. That takes data. Data costs money.
If you can’t commit £1,000/month for at least two months, you’re better off spending that money on Checkatrade or getting your Google Business Profile properly set up.
4. You’re decent on the phone
Leads are one thing. Turning them into jobs is another. If you’re not confident explaining your prices, handling “you’re too expensive” objections, or booking people in on the spot, Google Ads will hurt.
You’ll spend £50 getting someone on the phone, then lose them because you said “I’ll email you a quote” instead of “I can be there Thursday at 2pm, does that work?”
What the Numbers Look Like in Practice
Let’s run the maths on a realistic example.
Scenario: Solo electrician, Midlands town, £800/month Google Ads budget
- Clicks per month: 80 (at £10/click average)
- Leads generated: 16 (assuming 20% of clicks turn into a phone call or enquiry)
- Cost per lead: £50
- Jobs won: 6 (assuming you close 1 in 3 leads — realistic for trades)
- Cost per job: £133
- Average job value: £450
- Gross profit per job: £180 (40% margin after materials/time)
- Total profit from ads: £1,080
- Ad spend: £800
- Net profit: £280/month
Not life-changing. But that’s month one. By month three, if you’ve been tweaking keywords, pausing what doesn’t work, and improving your Google Quality Score, those numbers improve. Cost per lead drops to £35–£40. Conversion rate climbs to 35%. Suddenly you’re making £600+/month profit.
Now compare that to Checkatrade at £35/lead with a 15% close rate, or MyBuilder at £25/lead with even lower conversion. Google Ads starts looking better.
Local Services Ads vs Regular Google Ads
Most sole traders don’t realise there are two types of Google Ads for trades.
Regular Google Ads (Search Ads)
- You pay per click
- You control keywords, locations, budgets
- Requires ongoing management
- No trust badge
- Works for any trade
Google Local Services Ads (LSAs)
- You pay per lead (call or message only)
- Google controls who sees your ad based on reviews, location, response time
- Much simpler setup
- Shows “Google Guaranteed” or “Google Screened” badge
- Only available for certain trades (plumbers, electricians, locksmiths, HVAC)
For most one-man bands, Local Services Ads are a better starting point. You’re not paying for tyre-kickers. Every charge is an actual phone call or message. If someone rings and hangs up in 3 seconds, you can dispute it.
LSAs also appear above regular Google Ads. They’re the first thing people see. And the Google Guarantee badge adds instant trust you can’t buy with Search Ads.
Typical LSA costs in the UK:
- Plumber: £15–£50 per lead
- Electrician: £18–£45 per lead
- HVAC/heating engineer: £20–£60 per lead
The catch? You need good reviews (aim for 10+ Google reviews at 4.5+ stars), a verified business, and you have to respond fast. Google tracks your answer rate. Drop below 50% and your ads stop showing.
The Mistakes That Kill ROI
We see the same problems over and over with small trades businesses trying Google Ads.
Mistake 1: Broad targeting
You can’t afford to show ads for “plumber” across Greater Manchester when you’re one person covering Stockport. Tighten your radius to 5–10 miles. Target specific postcodes. Every wasted click is money you can’t get back.
Mistake 2: No tracking
If you don’t know which keywords brought in which jobs, you can’t improve. Use call tracking (services like WhatConverts start at £35/month) or at minimum, ask every caller “how did you find me?”
Mistake 3: Landing on your homepage
Someone clicks “emergency electrician Leeds” and lands on your homepage with a big photo of you holding a drill and three paragraphs about your qualifications. They’re gone in 4 seconds.
Send them to a page that says “Emergency Electrician in Leeds — Call 07XXX Now” with your phone number massive at the top. That’s it. You don’t need fancy. You need fast.
Mistake 4: Giving up after three weeks
We had a roofer spend £600 in three weeks, get four leads, win zero jobs, and pull the plug. Turns out his phone greeting was “yeah?” and he didn’t return calls same-day.
Google Ads didn’t fail. His process failed.
Give it 8 weeks minimum. Track everything. Adjust based on what the data tells you, not what your mate down the pub says.
Do You Actually Need Google Ads?
Here’s the question nobody asks: is Google Ads the best use of that money right now?
If your Google Business Profile isn’t set up properly, you’re leaving free leads on the table. If you’ve only got 3 reviews, spend £500 getting more before you touch paid ads.
If word of mouth keeps you busy 9 months a year but you’re quiet in January and February, Google Ads in those two months might be all you need. Don’t run them year-round just because someone told you to “always be marketing.”
And if you’re charging £80 call-outs with no repeat work, Google Ads probably isn’t for you. Sort your pricing first. Then revisit.
The Bottom Line
Google Ads can work for one-man trades businesses. But only if:
- You’ve got enough margin to absorb £750–£1,500/month for 8–12 weeks
- Your average job value is £300+
- You answer your phone fast and convert leads well
- You’re willing to track, test, and tweak constantly
Start with Google Local Services Ads if you’re a plumber, electrician, or locksmith. Pay-per-lead beats pay-per-click when you’re learning. If LSAs aren’t available for your trade, or you want more control, regular Search Ads work — but budget properly.
And if you’re still not sure, that’s fine. There’s no rule that says you have to do Google Ads. Plenty of sole traders grow beyond word of mouth and make £150k+ a year without spending a penny on them.
