Where can I buy a list of UK plumbers with the owner's name, address and phone number?
You can buy it here as an Excel or CSV file. We hold 10,959 plumber records, each with a postal address and a phone number, and 10,212 of them give a person's name. Only 2,570, about 23%, hold that person's own email, which is thin. Heating engineers, boiler firms and gas engineers are held separately, so say if you want them counted too.
What you get when you buy plumbers data
Each record is one plumbing business, named as the customer knows it, at the address it trades from. Here is what that gives you for each way of getting in touch.
| Channel | Records with it | Share | Coverage | What it means for plumbers |
|---|---|---|---|---|
| Post | 10,959 | 100% | Strong | Every one of the 10,959 records has an address. For a plumber working alone this is usually a house, so your letter reaches the person who runs the business rather than a post room. Keep it to one page they can read at the end of the day. |
| Phone | 10,959 | 100% | Strong | There is a number on every record. Many will ring through to someone working in a customer's home, so a short call that asks for a better time to talk tends to go further than a full pitch. |
| Named contact | 10,212 | 93% | Strong | 10,212 records, about 93%, give a name. In this trade that is nearly always the owner, so a named letter or a call asking for them by first name reaches the buyer. |
| Email | 2,570 | 23% | Thin | Just 2,570 records hold the named person's email. That is too few to carry a campaign on its own, and some of them belong to sole traders who need to have opted in first. |
| General email | 892 | 8% | Usable, with care | Another 892 records have a general business address only. Plumbers use these for customer bookings and emergencies, so a sales email there is easy to overlook or delete. |
Records with each contact channel (10,959 plumbers in all)
What to do about thin email. Buy for post and phone and treat email as a bonus on the records that have it. A simple pattern works: a letter first, a call a week later to the same named owner, then an email only to the limited companies that hold one. If an owner asks for details by email on the call, note that they asked. Don't pay extra to cut the list down to email records unless you have no way to post or call.
Plumbing and heating are filed apart. A firm sits in the category that best matches how it describes itself. So a business that mostly fits boilers may be under central heating systems (3,784 records), heating contractors (1,120), gas service engineers (1,305), boiler servicing and repairs (802) or gas installers (776), not under plumbers. Many do both kinds of work. If your product suits anyone who fits pipework or boilers, add those categories to your count; if it is plumbing only, leave them off and the price stays lower.
Merchants are not plumbers. Plumbers merchants (2,540 records) are the shops plumbers buy from, held in their own category. Take them only if you sell to stockists. Bathroom planners and furnishers and drainage firms are also separate.
Trading names hide legal form. "A Jones Plumbing & Heating" could be a limited company or one person. The record tells you the name and size band, not whether it is incorporated.
Who the named contacts are
The named person is usually the owner, who also does the work, quotes for it and chases payment. Decisions on tools, vans, software and insurance are made by them, often quickly and without a meeting. In firms with staff the owner may have a director title, and an office manager or a family member runs the diary and the bills; that person is the one who answers the office phone but rarely the one who signs.
- Owner
- Proprietor
- Director
- Managing Director
- Office Manager
- Partner
We don't hold trade body membership or registration status on the records, and there is no selection for it. If your offer depends on the plumber holding a particular registration, check that with the firm itself or the scheme's own search before you rely on it.
Selections worth paying for with plumbers
These are the selections on offer. The verdicts are for plumbers, where most records name the owner and every record has an address and phone number.
| Select by | For plumbers | Why |
|---|---|---|
| Type of business | Worth it | The decision that changes the order most. Choose plumbers alone, or add the heating and gas categories, and keep merchants out unless you sell to them. |
| Number of employees | Worth it | Separates the owner working alone from firms with fitters and an office. Ask for the count by size band so you can see how many of each you would be paying for. |
| Postcode area or radius | Worth it | Useful when you visit, deliver or fit locally. Set the radius to the distance your team will actually travel. |
| Region or county | Worth it | A quick way to test one area first, then repeat the order elsewhere if it works. |
| Records with an email only | Rarely needed | Leaves 2,570 records, under a quarter of the list, at a higher price per record. Worth it only if email is your sole route and you can screen out sole traders. |
| Job title | Rarely needed | Most named contacts are the owner already. Cutting by title just shrinks the list. |
| Turnover | Rarely needed | A small plumber's takings move with the work they win, so staff numbers are a steadier guide to size. |
| Records with a phone number only | Rarely needed | All plumber records already have a number. This changes nothing. |

Price per 1,000 records by order size (excluding VAT)
Cutting to email-only records costs more per record, because the order falls into a smaller band. The 2,570 email records come to £693.90; the full 10,959 records cost about three and a half times that and give you more than four times the addresses and phone numbers. Adding heating firms keeps you in the £220 band and lifts the share of named emails, since heating contractors hold 510 named emails across 1,120 records.
Licence, accuracy, screening and delivery
A plumber you write to in summer may only have time to think about new kit in a quiet spell, so the 12-month licence lets you come back without paying again. Phone numbers are screened for 28 days from delivery; if your calls go on longer, screen again. The accuracy guarantee covers wrong records you can show us, such as returned letters, so keep anything the post office sends back.

| All UK workplaces in SIC 43220 | 48,500 | 100% |
The ONS counts for SIC 43220 cover plumbing, heating and air-conditioning installation together. They show about 78% of workplaces run by companies, about one in five by sole traders and about 3% by partnerships, and only count firms registered for VAT or PAYE. One-person plumbers below those thresholds are missing, so expect more sole traders on a plumbers list than the figures suggest.
That affects email more than post or phone. The ICO says you must not email or text individuals without specific consent, sole traders and some partnerships count as individuals, and the existing-customer exception doesn't stretch to contacts on a bought-in list. The ICO also notes there is no email version of the TPS, so there is nothing to screen email addresses against: the check is yours. Look up a firm on Companies House before you email it, and send nothing by text to an owner's mobile without consent.
Before you buy plumbers data: questions to settle
- Plumbing only, or heating and gas too? Decide which categories go into the count before you compare quotes.
- Do you sell to merchants? If not, make sure plumbers merchants are left out.
- Which size bands? Ask for the split by employees so you don't pay for one-person firms you can't serve, or the reverse.
- Is your plan post and phone first? With about 23% holding a named email, it needs to be.
- Who checks legal form before emailing? Agree a Companies House check for every address you plan to email.
- Does your offer need a registration? We don't hold it, so plan how you will confirm it.
