The forgotten-database problem in plumbing

Every boiler you’ve ever serviced is on an annual cycle. Every emergency call-out you’ve ever handled is a customer who already trusts you with their property. Most plumbing firms have years of past customers in their records and never email them — they spend on Google Ads to acquire strangers instead.

How the campaign works

Customer Revival is a done-for-you 7-email Monday-to-Friday campaign sent to your existing customer list — past jobs sitting in your records for 12 months or more. We pick a relevant theme — annual boiler service reminder, winter prep, pre-summer cylinder check, landlord gas-safety renewal — and write seven emails in your firm’s voice. You approve every word before send.

Why this works for plumbing and heating

Acquiring a new boiler-service customer costs £80–£200 through Google Ads. Reactivating one from your database costs almost nothing. We’ve seen this framework book 47 jobs in 4 days for one local service business — the niche changes, the principle doesn’t. Old customers are far easier to bring back than new ones are to win.

Compliance and tone

We send only to customers you’re entitled to contact under UK PECR Regulation 22 soft opt-in rules. Every email contains a working unsubscribe link, your business postal address, and matches ICO direct marketing guidance. No fictional emergency claims, no fear-based fake urgency.

Which plumbing sub-niches we work with

Best fit for Gas-Safe-registered plumbing firms doing boiler installs, annual servicing, repairs, emergency call-outs, bathroom installs, and commercial heating. Minimum 500 past customers with email addresses on file. We don’t currently work with one-man-band sole traders below that threshold — the maths doesn’t work.

What the seven emails actually say

Monday opens on the thing plumbing customers never think about until it fails — the parts of a system that quietly degrade on a schedule. Tuesday explains what a check involves and what it typically catches. Wednesday makes the offer. Thursday addresses the honest objection, which is that nothing appears to be wrong. Friday is a short close with a clear booking route.

Two mid-week re-sends go to non-openers. Themes rotate across campaigns — annual system check, unvented cylinder service, bathroom refits for customers three-plus years past their last one, water softener servicing, and pre-winter pipe checks. The refit theme behaves completely differently to the maintenance themes and usually needs its own campaign.

What we need from you

Name, email, job date and, if you have it, job type. Anything from Commusoft, Tradify, ServiceM8 or a spreadsheet works. Messy exports are the norm and we clean them.

Choose your theme, we write the seven emails in your voice, and you read them all before anything is scheduled. 48-hour revision window, unlimited rewrites inside it, nothing goes out without your sign-off.

Getting ready for the calls

Split your thinking between the two kinds of response you’ll get. Maintenance enquiries want a diary slot and a price. Refit enquiries want a conversation and a quote visit, and they take far longer to close. If you run a refit theme, block out survey time; if you run a maintenance theme, block out job time.

Agree the fixed price before the campaign goes out. Improvised pricing on the phone is the most common reason a good campaign converts badly.

What this is not

It is not emergency call-out marketing and it is not a source of new customers. Everyone on the list has already had you in their home. Growing the list itself is a separate job with separate mechanics.

We don’t take on lists under 500. The complete UK guide covers the full framework if you’d rather read first.
