A customer having a bathroom fitted may need a plumber, an electrician, a tiler and a decorator. Each business handles a different part of the project, but they all have a reason to know someone reliable for the next stage.
That is where cross-trade referrals come in: one trades business recommends another, complementary trade when a customer needs work outside its own services.
The opportunity is straightforward. If you already work alongside good tradespeople, you have the beginnings of a useful network. The next step is to make those recommendations easier to give, easier to follow up and worth trusting.
A recommendation gives a customer a starting point. Instead of choosing a business they know nothing about, they can speak to someone recommended by a tradesperson they already know.
For example, a plumber replacing a bathroom notices that the customer will need a tiler once the plumbing is finished. If the plumber knows a reliable local tiler, an introduction can help the customer organise the next stage.
There are practical reasons to build these relationships:
Relevant timing. You can make an introduction when a customer has an identified need, rather than hoping your marketing reaches them at the right moment.
A clearer fit. Partners who understand your services and working area can recognise suitable opportunities.
Useful context. A customer can explain what they need, with an introduction that makes the first conversation less of a cold start.
No advertising charge for the introduction itself. Informal recommendations do not need a paid campaign, although maintaining the relationships still takes time.
None of this guarantees a booking. Customers may still compare quotes, check reviews or choose another contractor. A recommendation opens the conversation; your response, pricing and service still need to earn the work.
You do not need a formal scheme to begin. Start with a few complementary businesses whose work and approach you trust.
Think about the trades you regularly meet on jobs. Who communicates clearly, respects the customer's property and completes work to a standard you would be comfortable recommending?
Look beyond the finished result. Consider how they handle delays, changes and problems too. Your customer will experience all of that, not just the workmanship.
If you have not worked together before, ask about relevant experience and references before making an introduction. Check qualifications, registrations and insurance where relevant to the work. A recommendation should not replace those checks.
“Send anything our way” gives a partner very little to work with.
Tell them which services you offer, which areas you cover and what falls outside your scope. Be clear about availability and whether you handle emergency call-outs, small repairs, installations or ongoing maintenance.
A useful introduction might sound like this:
“We mainly handle domestic plumbing repairs and bathroom installations around the local area. We don't take on electrical work, so it's helpful to know someone we can recommend when customers need both.”
Ask the same questions about their business. Knowing that an electrician focuses on commercial installations, for example, can prevent an unsuitable domestic enquiry.
You do not have to wait for another business to send you work first. If a customer needs a service you do not provide and you know someone suitable, offer an introduction.
Keep the customer's needs ahead of any expectation of getting work back. Different trades encounter different opportunities, so a useful relationship will not always produce an equal number of jobs in each direction.
If someone repeatedly ignores enquiries or lets customers down, reconsider recommending them. Reliability matters more than balancing a tally.
“Try someone I know” leaves the customer with more work to do. Give them the business name, the right contact details and a short explanation of why that business may be suitable.
Let the customer decide how to proceed:
“I know a tiler whose work I've seen on other bathroom jobs. Would you like their number, or would you prefer me to ask them to contact you?”
If the customer wants an introduction, agree what information you will pass on. A useful handover may include:
The customer's preferred contact method.
A brief description of the work they want discussed.
The general location and any relevant timing.
Confirmation of who will make the next contact.
Do not promise another business's price or availability unless it has confirmed those details.
If you receive an introduction, acknowledge it and contact the customer within the timeframe you agreed. If you cannot take the work, say so promptly.
Thank the business that made the introduction, but do not assume it needs the customer's quote, invoice or other private details. Close the loop without sharing more information than necessary.
If a customer later raises a concern about someone you recommended, listen and take it seriously. You may not be managing the job, but their experience should inform future recommendations.

Payment is not necessary to start a useful relationship with another trade. A recommendation can simply help a customer find the right person while supporting a business you trust.
If you do agree a fee, put the terms in writing. Cover what triggers payment, the amount, when it is due and what happens if the work is cancelled or the customer does not pay. Check the arrangement against your contracts and any relevant professional or legal requirements.
Be open with customers about financial incentives or arrangements that could influence your recommendation. As a practical transparency measure, a plain explanation is better than leaving them to discover it later:
“We work with this business and receive an introduction fee if you book. You're free to use another contractor.”
A fee should never be the reason to recommend someone whose work you would otherwise question.
The simplest option is often to give the customer the other business's details and let them make contact.
If you will be sharing the customer's information instead, explain who will receive it and why. Ask whether they want you to make the introduction, and only pass on what is needed for that purpose. Avoid forwarding entire job records, photographs or documents when a short description would do.
Customer agreement is a sensible part of the conversation, but it is not a substitute for checking your data protection responsibilities. The UK's Information Commissioner's Office guidance on lawful data sharing explains that you must identify a lawful basis before sharing personal data. Ireland's Data Protection Commission guidance on lawful processing sets out the lawful grounds under Article 6 of the GDPR.
Consent is one possible lawful basis, not the only one. Make sure your approach fits the circumstances rather than assuming that an informal introduction sits outside data protection rules.
A recommendation introduces a customer to another business. Subcontracting brings another business into work you have agreed to deliver.
For a straightforward referral, the customer normally agrees the scope, price and booking directly with the recommended trade. That business carries out the work under its own agreement with the customer.
With subcontracting, you engage another business to carry out part of your job. You need clear arrangements for the work, payment, communication and completion records. Responsibilities depend on the contracts and circumstances, so do not treat it as an informal introduction with a different name.
Consider a bathroom installation that needs specialist tiling:
Referral: you give the customer a tiler's details, and the customer arranges the tiling separately.
Subcontracting: you include tiling in your agreed scope and engage a tiler to complete that part of the project.
Before subcontracted work begins, agree who will provide instructions, communicate with the customer, approve changes and check the completed work. Confirm competence and insurance as appropriate, and do not take on work outside your ability to manage it safely.
If you are coordinating the job, a phone number and a verbal description are not enough. Give the contractor a clear scope, relevant site information, access arrangements and the completion records you need back.
Decide how updates, variations, photographs and outstanding issues will be recorded before work starts. That gives everyone a shared understanding of what needs to happen next.
Fieldmotion's field service management software brings scheduling, job records, digital forms and invoicing into one platform. If subcontracting is part of your operation, discuss the specific external-contractor workflow with the team so you can confirm how it fits your process.
A simple record can tell you more than a general impression that a partnership is going well.
For each enquiry, note who made the introduction, the type of work requested, whether it suited your business and whether it became a completed job. If you paid an introduction fee, record that too.
Review the pattern periodically. A partner who sends occasional, well-matched enquiries may be more useful than one who sends plenty of work outside your area or expertise.
Avoid judging a new relationship on one enquiry. Look for service quality, customer fit and consistent communication over time.
Choose a trade whose work you already trust. Check what they are taking on, explain the work you handle and agree how you would introduce a customer when the need arises.
The next time a customer asks for help outside your scope, you will have a clearer answer than “you'll need to find someone else”.
Cross-trade referrals happen when one trades business recommends another that provides a complementary service. For example, a plumber may recommend an electrician when a customer needs electrical work as part of a bathroom renovation.
Start with businesses whose work you have seen and whose communication you trust. Check relevant experience, references, insurance and any qualifications or registrations needed for the work. Do not base a recommendation only on a promise to send work back.
Not automatically. A recommendation can provide a relevant introduction, while advertising can reach customers beyond your existing network. Compare suitable enquiries, completed jobs and acquisition costs for your own business rather than assuming one channel always performs better.
No payment is needed to begin an informal recommendation relationship. If you choose to offer a fee, agree the terms clearly, check any applicable requirements and be transparent about incentives that could influence the recommendation.
Explain the proposed introduction and ask whether the customer wants you to share their details. You must also establish an appropriate lawful basis for sharing personal data. The ICO's data-sharing guidance and the Irish Data Protection Commission's lawful-processing guidance explain the relevant principles.
A referral normally leaves the customer to agree and pay for work directly with another business. Subcontracting means you engage another business to deliver part of a job you have taken on. Scope, payment, communication and responsibilities should be agreed before work starts.
