How to Find Work as a Self-Employed Plumber (UK Guide 2026)

By Paul Lewis — time-served tradesman with over 40 years in the building services industry, former owner of his own contracting business, and five years teaching apprentices and adult learners in further education.

The biggest worry for most plumbers going self-employed isn’t the plumbing. It’s whether the phone will ring. The good news is that plumbing is always in demand. The challenge is getting your name in front of the right people and turning enquiries into booked jobs. This guide covers where the work comes from when you’re starting out, and how to keep it coming.

1. Start with people who already know you

Your first jobs will almost certainly come from people you already know: friends, family, neighbours, former customers from your employed days, and other tradespeople.

• Tell everyone that you’re now working for yourself, in person, by text and on your own social media.
• Give them something to pass on, such as a business card or a link to your Google Business Profile.
• Do the first jobs brilliantly. Every one of those customers knows other people who need a plumber.

Check your employment contract before contacting your old employer’s customers. Some contracts don’t allow it for a set period after you leave.

2. Work with builders and other trades

Builders, kitchen fitters, bathroom fitters, electricians and property developers all need a reliable plumber. One good relationship can keep you busy for years.

• Introduce yourself to local builders and fitters. A short call or a visit to a site is often better than an email.
• Be reliable above all else. Turning up when you say you will, and finishing on time, matters more to a builder than being the cheapest.
• Expect to work under the Construction Industry Scheme (CIS) if you work for builders. Register before you start.

When starting out, Subcontracting to a builder or larger plumbing firm on a day rate is also a good way to bring in steady money while you build your own customer base.

3. Target landlords and letting agents

Landlords and letting agents are some of the best customers a plumber can have. They have lots of properties, regular repairs, and they want one number to call.

• Contact local letting agents and ask to be added to their list of contractors. Be ready to show proof of insurance and qualifications.
• Respond fast to their call-outs. Agents remember who turned up quickly for an urgent leak.
• Offer landlord gas safety checks if you’re Gas Safe registered. Every rented home with gas needs one every year, which means guaranteed repeat work. Not sure if you need registration? See Do you need Gas Safe registration to start a plumbing business?

4. Set up a Google Business Profile on day one

When someone searches “plumber near me”, the businesses listed on the map come from Google Business Profile. It’s free, and for a local plumber it’s the single most useful thing you can set up online.

• Fill in everything: your services, the areas you cover, your opening hours and a phone number you’ll answer.
• Add photos of your work, your van and yourself.
• Ask every happy customer for a review, and make it easy by sending them the link by text straight after the job.
• Reply to every review, good or bad, politely.

A handful of genuine reviews will move you up the local results faster than almost anything else.

5. Use free local channels

• Local Facebook groups and community pages. People ask for plumber recommendations in them every day. Join the groups for your area and respond helpfully when someone asks.
• Van signage. Your van is parked outside customers’ houses all day. Clear lettering with your name, phone number and website costs a few hundred pounds and works for years.
• Leaflets and cards for neighbours around jobs you’re working on. People often realise they have a job of their own when they see a plumber next door.

6. Consider paid lead and directory sites carefully

Paid directory and lead sites can fill gaps in your diary when you’re starting out. But you pay for membership or for each lead, many plumbers may be competing for the same job, and the customers are often shopping on price.

Use them as a top-up, not your main source of work. Keep track of what you spend and what work you win, and stop using any site that doesn’t pay for itself.

7. Turn enquiries into booked jobs

Getting the enquiry is only half the job. Many new businesses lose more work at this stage than they realise.

• Answer the phone, or call back within the hour. The first plumber to respond often gets the job.
• Turn up for quotes when you say you will.
• Send clear written quotes quickly, saying exactly what’s included.
• Follow up a few days later if you haven’t heard back.

8. Keep the customers you’ve won

It’s far easier to get work from an existing customer than to find a new one.

• Keep a record of every customer and what you did for them.
• Send reminders for annual boiler services if you’re Gas Safe registered.
• Leave every job clean and tidy. That’s what customers remember and talk about.

9. As you grow: contracts and tenders

Once you’re established, housing associations, councils, schools and property management companies offer regular maintenance contracts. These are usually awarded through tenders. Our guide Winning Work explains how small trade businesses can find and win this kind of work.
