Customer finance, explained in plain terms

Customer finance lets your clients spread the cost of plumbing work into manageable monthly payments, rather than paying the full amount upfront. In practice, it turns a large, one-off invoice into a predictable plan, often with options such as 0% interest over 12-24 months or low-APR repayment over 3-5 years. For your business, it is less about “discounting” and more about removing friction at the point a customer is deciding whether to proceed, upgrade, or postpone.

Offering finance is increasingly part of how UK homeowners buy big-ticket home improvements. When the customer can see an exact monthly figure and a clear total repayable, it becomes easier for them to say yes with confidence.

Understanding APR isn’t just about percentages - it’s about knowing what you’ll pay in real terms.

Why homeowners choose finance for plumbing and heating

Plumbing, boilers and bathroom projects often arrive with urgency, limited savings, or competing household priorities. Even when a customer can afford the work, many prefer to keep cash in the bank and smooth payments across months, especially for planned upgrades like bathrooms, underfloor heating, or water-saving fixtures. In this sector, finance is also about certainty: a set monthly payment can feel safer than putting a large amount on a credit card and hoping the balance is cleared quickly.

The market has moved towards retail-style flexibility. Many customers now expect to see interest-free options, low-APR alternatives, and familiar payment brands for mid-ticket purchases. If those choices are not available, the customer may simply keep shopping.

How finance helps you sell more (without hard selling)

Finance typically lifts conversion because it reframes the decision from “Can we afford £4,000 today?” to “Does £85-£110 per month fit our budget?”. In UK plumbing and heating, 0% plans over 12-24 months and low-APR options around 7.9%-11.9% over 3-5 years are now commonly seen for boilers and bathrooms, making them a competitive baseline. Longer terms can push the monthly payment even lower, but they also increase the total repaid, so transparency matters.

Finance can also increase average order value. Customers who planned a like-for-like replacement may choose a better boiler, smart controls, or higher-spec bathroom fittings once monthly payments are made clear. Done properly, it is a service feature that builds trust because you are helping them choose the right solution, not just the cheapest invoice.

Standout line: The most profitable jobs are often lost at the moment of payment, not the moment of need.

The FCA angle: what you must get right

If you introduce customers to third-party finance, you need to treat it as a regulated journey and present information clearly. Representative APR, term length, deposit (if any), monthly payment and total amount repayable should be easy to find and consistent with the lender’s offer. Avoid pressure selling, ensure customers understand that finance is subject to status, and keep promotions balanced (for example, don’t emphasise “from £40 per month” without explaining key assumptions). Good record-keeping and approved wording protect both your firm and your customers.

Introducer and broker set-ups: how it works in the real world

Most plumbing firms do not become a lender. Instead, they act as an introducer: you present finance as a payment option, then the customer applies through a regulated lender panel via a broker platform. The broker typically handles lender access, application flows, eligibility checks and decisioning, and can offer multiple products such as 0% interest plans, low-APR instalments, and sometimes interest-free periods through familiar payment brands.

For you, the operational benefit is simplicity. The customer completes an application, many journeys return a decision quickly, and you can focus on surveying, quoting and delivering the job. For the customer, the value is choice and clarity: short-term interest-free for those who can repay quickly, and longer-term plans for those prioritising monthly affordability.

What the customer journey looks like (step by step)

1. Quote the job as normal with a clear scope, price, and optional upgrades.

2. Offer payment choices: pay in full, deposit plus balance, or finance.

3. Show example plans that match the job value (term, APR, deposit rules), including total repayable.

4. Customer applies via a secure online application on mobile, tablet or desktop.

5. Decision returned (often quickly), with the customer selecting their preferred plan.

6. You confirm the order and schedule installation once the agreement is in place.

7. Complete the work and follow your usual sign-off process.

8. Customer repays monthly to the lender under the agreed terms.

9. Aftercare and reviews: follow up, remind them finance enabled the upgrade, and request a review or referral.

Next step suggestion: Add a “Spread the cost” panel to every quote and invoice template so finance is introduced consistently, not awkwardly.

Kandoo is a UK-based retail finance broker, so the goal is to help you offer customer finance in a way that feels straightforward for your team and transparent for your customers. Start by deciding which job types you want to finance most often (boilers, bathrooms, or whole-home upgrades), then build a simple set of example repayments that fit your typical price points. Once your journey is set up, train your team to present finance as a normal payment option, using the same calm language every time and always including representative APR and total repayable where required.

The quickest wins usually come from consistency: finance mentioned on your website, in follow-up emails, on quotes, and during survey visits. When customers can see the numbers clearly, the conversation becomes practical rather than persuasive.

FAQs

Q: Do I need to offer 0% finance to compete? A: Not always, but in boilers and bathrooms many UK firms now present 0% over 12-24 months alongside low-APR options. A sensible approach is to offer both: interest-free for short terms and low-APR for longer affordability.

Q: What monthly payment examples resonate with customers? A: Clear, realistic examples. For instance, longer-term plans can make a £5,000 job look like roughly £100-£110 per month depending on APR and term, while retail-style 0% plans can start from around £40 per month on smaller baskets.

Q: Can I offer finance with no deposit? A: Sometimes. Some providers and products allow no-deposit finance, while others use deposits (often tiered) to manage risk and keep offers competitive. The key is to present deposit rules upfront.

Q: Is buy now pay later suitable for plumbing work? A: It can be useful for mid-ticket upgrades where customers want flexibility and minimal commitment. It often works best for supply-heavy jobs or where customers are comfortable with familiar checkout-style payment journeys.

Q: Will offering long terms create complaints about interest? A: It can if total cost is not explained. Longer terms reduce the monthly payment but increase total repayment, sometimes significantly over many years. Show the total repayable and ensure customers choose based on both figures.

Q: Does offering finance slow down the sales process? A: Done well, it often speeds up decisions. Instant or near-instant decisioning is common with modern broker-powered journeys, reducing the back-and-forth that happens when customers need time to “work out the money”.

Q: What should my website say about finance? A: Keep it clear and compliant: representative APR (where relevant), example costs, term ranges, deposit expectations, and “subject to status” messaging. Make it easy to find on boiler and bathroom service pages.

Q: What is the biggest mistake plumbing firms make with finance? A: Only mentioning it after the customer hesitates. Finance works best when it is presented early as a normal option, with transparent numbers and no pressure.
