Google Local Service Ads vs Google Ads for UK Plumbers in 2026
Which paid Google product actually books more plumbing jobs? Real numbers from 40+ live UK plumber campaigns comparing LSA and regular Google Ads (PPC) side by side.
For UK plumbers, LSA wins by 8 to 15 times on cost per booked job.
Google Local Service Ads (LSA) sits above every regular Google Ad with a Google Guaranteed badge and pay-per-verified-lead pricing. UK plumber leads cost £22.40 on average and convert at 34% to £65 per booked job. Regular Google Ads for the same plumbing search terms cost £213 per lead and convert at 22% for £970 per booked job. LSA should be your primary channel. Regular Google Ads still has a place for keywords LSA doesn’t cover.

Why LSA outperforms Google Ads for plumbers
Four structural reasons LSA books more jobs per pound spent.
You pay for leads, not clicks
On Google Ads, someone clicks your ad, you pay, and 83% of the time they never enquire. On LSA you only pay when the customer calls, messages or books through the ad. Every pound you spend on LSA is attached to a real enquiry.
Google verifies the enquiry before you pay
Google confirms job type, postcode and urgency. If someone contacts you outside your service area or for a service you don’t offer, you can dispute the lead and get a refund. We win 85% of disputes on well-argued cases.
Google Guaranteed badge sells for you
The green tick badge on LSA ads is earned through Gas Safe check, insurance verification and DBS. Customers trust badged tradespeople more, so they call before comparing prices. Regular Google Ads have no equivalent trust signal.
LSA sits above everything else
LSA slots are physically the highest paid result on the page, above every regular Google Ad. Even when a competitor spends more on Google Ads, if you are on LSA you are seen first.
When to use each channel
LSA is not universal. Google Ads still has real use cases for plumbers.
Use Google Local Service Ads when
- You are Gas Safe registered (for boiler categories) or hold public liability insurance for non-gas
- You need booked plumbing jobs this month, not clicks
- You have a Google Business Profile with 5+ reviews
- You can respond to leads within 5 to 15 minutes
- You are willing to complete the 2 to 4 week verification
- Your service area matches at least one UK postcode with LSA availability
Use Google Ads when
- You need to target specific search terms LSA doesn’t cover
- You have a landing page for a specific service (e.g. Vaillant boiler installation)
- You are targeting commercial plumbing keywords which LSA doesn’t index well
- You need to run ads immediately while LSA verification completes
- You are targeting brand terms like “your business name” to defend against competitors
- You want to remarket to visitors who saw your website but didn’t call

Frequently asked questions
Should I run LSA and Google Ads together?
Yes for most established plumbers. Use LSA as your primary channel to book jobs, and use Google Ads for specific keywords LSA doesn’t cover (branded terms, commercial plumbing, specific manufacturers, remarketing). LSA covers 60 to 75% of your paid lead volume, Google Ads fills the rest.
What is the minimum weekly budget for each?
LSA: £100 to £200 per week is the minimum viable spend. Google Ads: £150 to £300 per week. Below these, algorithms cannot optimise and cost per result rises sharply.
Can non-Gas Safe plumbers use LSA?
Yes, for non-gas categories only: General Plumbing, Emergency Plumbing, Drain Unblocking, Leak Repair and Radiator Installation. Boiler Installation and Boiler Repair require Gas Safe registration.
How long is LSA verification for plumbers?
2 to 4 weeks typically. Google verifies your business licence, insurance, Gas Safe registration and DBS. Once verified, ads go live within 24 hours.
Why is Google Ads so much more expensive per job for plumbers?
Three reasons: 1) You pay per click regardless of intent, 2) Only 17% of clicks convert to a lead, 3) Only 22% of those leads book jobs. Compounded, 3.7% of Google Ads clicks book a job. On LSA you pay per lead and 34% of leads book. Very different economics.
Can I dispute Google Ads clicks like LSA leads?
No. Google Ads has a limited invalid-click filter that refunds automated bot clicks, but you cannot dispute a real human clicking your ad who didn’t turn into a customer. LSA disputes give you a genuine refund path.
Which converts faster, LSA or Google Ads?
LSA. Verified LSA leads book within 24 to 48 hours 71% of the time. Google Ads leads (from landing page forms) take longer because the customer is still comparing options. Response speed matters more on Google Ads because lead intent is lower.
