We're building a UK-wide network of accredited plumbers to meet growing demand for rainwater harvesting installations. Add a profitable new stream to your business.

Why Enrol With Rainwater Doctor?

Rainwater harvesting is one of the fastest-growing areas in UK plumbing and water management. With increasing pressure on water resources, rising utility costs, and tighter building regulations, more homeowners and businesses are turning to rainwater harvesting systems. As a Rainwater Doctor accredited plumber, you'll be at the forefront of this growing market.

We provide everything you need to deliver high-quality rainwater installations with confidence. From comprehensive training and technical support to a reliable supply chain and a steady stream of referrals, we set you up for success. You focus on the installation; we handle the rest.

What We Offer Accredited Plumbers

When you enrol with Rainwater Doctor, you gain access to a complete support system designed to make rainwater installation straightforward and profitable. Every aspect of the programme has been developed based on feedback from the plumbers already working with us across the UK.

We provide accredited training covering system design, installation best practices, commissioning, and aftercare. Whether you are new to rainwater harvesting or have some experience, our training ensures you can install our systems to the highest standard. Training is delivered through a combination of online modules and hands-on practical sessions.

Our technical support team is available to answer questions throughout the installation process. From reviewing system designs before you start on site to troubleshooting unexpected challenges, we are here to help. You are never alone on a Rainwater Doctor installation.

We also handle customer leads and referrals. When homeowners and businesses in your area enquire about rainwater harvesting, we recommend accredited plumbers from our network. This means a steady flow of qualified leads without the marketing cost or effort.

Who Can Enrol

Our programme is open to qualified plumbers and plumbing businesses across the UK. You should hold relevant qualifications and have experience in domestic or commercial plumbing installations. A commitment to quality workmanship and customer service is essential.

We welcome applications from sole traders, small plumbing businesses, and larger installation companies. Whether you want to add rainwater harvesting to your existing service offering or build a dedicated installation team, we have a membership level that suits you.

You do not need prior experience in rainwater harvesting to enrol. Our training programme is designed to take you from foundation knowledge to competent installer. What matters most is your willingness to learn and your commitment to doing the job right.

How the Enrolment Process Works

The enrolment process is straightforward. Start by completing our online application form, telling us about your business, qualifications, and the areas you cover. Our partnerships team will review your application and arrange an initial phone or video call to discuss the programme in more detail.

Following the introductory call, we will invite you to complete our training programme. Training typically takes two to three days depending on your existing experience level. Once you have successfully completed training, you will be added to our network of accredited plumbers and begin receiving installation referrals.

There is a modest annual membership fee that covers training access, technical support, marketing materials, and listing in our accredited plumber directory. We offer flexible payment options and do not lock you into long-term contracts. You can leave the network at any time.

What Our Accredited Plumbers Say

Plumbers in our network consistently report that adding rainwater harvesting installation has transformed their businesses. Typical benefits include higher average job values compared with standard plumbing work, reduced seasonality as rainwater installations are specified year-round, and increased customer satisfaction as homeowners see tangible savings on their water bills.

Several of our accredited plumbers have built dedicated rainwater installation divisions within their businesses, each generating six-figure annual revenues. Others value the variety that rainwater projects bring, working on interesting installations that range from small domestic systems to large commercial schemes.

We regularly survey our network and act on feedback to improve the programme. Recent improvements driven by plumber feedback include enhanced marketing support, a dedicated mobile app for job management, and expanded technical documentation including video guides.
