Most plumbers I talk to are spending somewhere between £0 and £2,000 a month on marketing. The ones spending £0 rely on word-of-mouth. The ones spending £2,000 are often getting burned out by Google Ads with no clear ROI.

Here's an honest breakdown of what actually works for UK plumbers in 2026 — ranked by ROI.

Channel 1: Missed Call Recovery (ROI: 500%+)

This isn't strictly "marketing" — but it's the highest-ROI thing you can do. Before you spend a penny on new leads, stop losing the leads you already have.

A missed call text-back system costs £197/month. One recovered job (a £250 call-out) covers it. Every job after that is profit.

Most plumbers we talk to are losing 3-5 calls a day. That's 60-100 calls a month they never answered. At a 25% conversion rate, that's £2,250-£3,750/month in lost revenue — and they don't even know it.

Cost: £197/mo · Potential recoverable: £1,000-£3,000/mo · ROI: 500-1500%

Channel 2: Google Business Profile (Free)

When someone in your area needs an emergency plumber, they Google. If your profile is optimised, you show up in the Local 3-pack — the map results at the top of the search page.

What to do:

Cost: £0. Time investment: 30 minutes setup, 10 minutes/week.

Channel 3: Checkatrade / Rated People (£5-30 per lead)

These platforms get mixed reviews from plumbers. The leads are expensive — £5 to £30 per enquiry — and you're competing with other trades on response time.

Key insight: the first to respond wins 60% of the time. If you use a missed-call text-back system, you can reply to platform leads in seconds (while you're on a job) instead of hours. That alone makes the platform profitable.

Channel 4: Google Ads (£500-2,000/month)

Google Ads works — but it's expensive and requires constant management. For emergency plumber keywords in London, you're looking at £5-15 per click.

If 1 in 10 clicks becomes a job (10% conversion), you're paying £50-150 per job before you do any work. That works if your average job is £200+, but the margins are thin and the management overhead is real.

Only invest in Google Ads after you've fixed missed calls and optimised your GBP. Otherwise you're just paying to drive leads into a leaky bucket.

Channel 5: Referral Program (£50-100/month in discounts)

Word-of-mouth is still the highest-quality lead source. Accelerate it: offer existing customers £50 off their next job for every new customer who books. Cost is low, trust is high, and these customers convert at 80%+.

The Right Order of Investment

  1. £0-£197 — Fix missed calls first (text-back system)
  2. £0 — Optimise your Google Business Profile
  3. £50-100 — Start a referral program
  4. £200-500 — Try Checkatrade/Rated People (with fast response)
  5. £500+ — Google Ads (only after the above are working)

Most plumbers skip step 1. They spend hundreds on ads and then miss the calls those ads generate. Fix the leak before you turn up the tap.
