1–4: The Highest-Impact Tactics
1. Google review collection (the #1 marketing action)
Ask every customer for a Google review on the day the job is completed. Send the review link immediately by text. Aim for 2–4 reviews per month minimum. This improves your local search ranking, increases your click-through rate, and reduces the price sensitivity of enquiries. No other marketing activity has a better return on time invested.
2. Google Business Profile optimisation
A complete, active Google Business Profile is your most important online real estate. Add all your services, service area, photos, and post regular updates. Respond to every review within 24 hours. A well-managed profile generates calls directly — no website needed, no advertising spend.
3. Annual boiler service reminder campaign
Your existing customer list is your most valuable marketing asset. Every September–October, send a reminder to every customer whose boiler you've serviced: "As we head into winter, it's a great time to book your annual boiler service. Booked customers are getting slots in [month] — shall I set one up for you?" This single campaign typically generates £5,000–£20,000 in bookings per year for an established plumber with a decent customer list. Automate this in your CRM.
4. Van livery and workwear
A branded van in a local neighbourhood generates a steady stream of calls. Every property you park outside is a potential customer. Full van livery costs £400–£800 and lasts 5+ years. Branded workwear (polo shirts, jackets with your company name and number) makes your team look professional and reinforces your brand with every customer visit.
5–8: Proven Growth Tactics
5. Referral incentive programme
Offer existing customers £20–£30 off their next invoice for referring someone who books a job. Word-of-mouth referrals arrive pre-sold on your quality — they convert at 3–5x the rate of cold leads and are often less price-sensitive. A simple referral card ("Tell a friend — you both save £25") left with every job costs pennies and generates recurring leads.
6. Letting agency and property manager relationships
One relationship with a letting agency managing 20–50 properties is worth more than any advertising spend. Visit agencies in person, leave professional materials, and offer structured maintenance services. Follow up every 4–6 weeks. Persistence and reliability win these relationships.
7. Before-and-after content on Instagram
Bathroom and heating installation before-and-afters perform strongly on Instagram and generate direct enquiries. Post 2–3 times per week. Use local hashtags (#[town]plumber, #bathroomrenovation[town]). Engage with local home improvement accounts and local community groups. This works particularly well for bathroom installation work.
8. Seasonal Google Ads campaigns
Run targeted Google Ads for "boiler repair [town]" and "emergency plumber [town]" during October–February (peak season). A budget of £200–£400/month during peak months, focused on high-intent emergency terms, typically produces 10–25 additional enquiries. Turn it off in summer when demand drops.
9–12: Supporting Tactics
9. Local business networking
Join your local Chamber of Commerce, Federation of Small Businesses, or a local BNI chapter. The referrals from these groups are modest but high-quality, and the relationships with other local businesses (builders, kitchen fitters, electricians) generate two-way referral traffic.
10. Newsletter or seasonal email
A quarterly email to your customer list — winter heating tips, summer pipe freeze prevention, a link to your latest reviews — keeps you top-of-mind without being intrusive. Mailchimp is free up to 500 contacts. The cost: 30–60 minutes per quarter. The return: steady inbound calls from customers who would otherwise have forgotten you.
11. Checkatrade or rated directory listing
A Checkatrade listing (£50–£100/month) generates leads for plumbers who actively collect reviews on the platform. It works best as one channel in a mix rather than your sole lead source. If you join, commit to getting reviews — the platform rewards high-review-count listings significantly.
12. Website with local content
A basic website with service pages, location targeting, and regular new content (blog posts about common plumbing problems, seasonal tips) ranks in organic Google search. The investment (£500–£2,000 to build, £50–£100/month to maintain) delivers leads indefinitely without ongoing cost once it ranks. Pair with Google Business Profile for the full local search presence.
