Home battery storage installers use 0% finance to turn a system that costs several thousand pounds into a monthly instalment a homeowner can approve on the spot, with the aim of shortening the gap between quote and signed order. Battery storage buyers behave differently from solar customers alone — they're often retrofitting an existing solar array, comparing three or four installers on price, and stalling at the finance question because nobody on the call can answer it cleanly.
- 0 finance battery storage installers convert quotes into signed jobs by splitting the invoice into interest-free monthly instalments at checkout.
- PayItMonthly lets installers offer 0% finance without carrying the credit risk or chasing repayments themselves.
- Present the monthly figure before the total price — installers who lead with cost-per-month close more battery storage deals in 2026.
- Vet every applicant through a proper eligibility check; skipping this step is the top cause of missed repayments in home improvement finance.
Why 0% finance matters for battery storage installers
A battery storage system is rarely bought on impulse. Homeowners research payback periods, compare installer quotes, and then hit a wall when the invoice lands as one lump sum. 0% finance removes that wall at the exact point a customer is ready to say yes.
Installers who only take card or bank transfer lose deals to competitors who can quote a monthly figure on the same call. That's the practical case for 0% finance battery storage installers keep coming back to: it's not a discount, it's a way to stop losing signed jobs to a payment method mismatch.
Battery storage also sits in the same buyer bracket as home improvement companies and solar panel installers — customers who've already accepted a five-figure home upgrade budget and expect flexible payment as standard, not as a favour.
Step-by-step: adding 0% finance to your battery storage quotes
Map the objection before it kills the quote
Most lost battery storage deals don't die on price — they die on payment friction at the moment of signing. Before changing anything, find where quotes stall.
- Review your last 10-20 lost quotes and flag how many mentioned budget, timing or "need to think about it"
- Ask your sales team where in the call the conversation goes quiet
- Check whether competitors in your area already advertise instalment options
- Note whether stalled quotes cluster around a particular system size or price band
Offer instalments as a checkout option, not a special favour
Homeowners respond better when finance is presented as a standard payment method, on the same footing as card or bank transfer, rather than something they have to ask for.
- List 0% finance on your quote template next to "cash" and "bank transfer"
- Add it to your website pricing page as a payment method, not a promotion banner
- Mention it in the first follow-up email after a site survey
- Make sure every quoting staff member can explain the monthly figure without escalating the call
This is where a platform like PayItMonthly replaces manual paperwork: instead of building your own credit-check process, the installer sends a link, the customer applies, and the decision comes back in minutes rather than days.
Segment your finance offer by system size
A 5kWh battery add-on and a full battery-plus-inverter retrofit are different sales conversations. Treat them differently in how you present monthly cost.
- Set a lower monthly instalment tier for entry-level battery packs
- Reserve longer instalment terms for combined solar-plus-battery installs
- Flag high-ticket retrofits for a dedicated finance conversation, not a rushed mention at the end of a call
- Cross-check your tiers against what best finance options for high-ticket retail purchases recommends for similarly priced categories
Train your sales team to lead with the monthly figure
Customers anchor on whatever number they hear first. If that number is the full invoice total, you've made your own job harder.
- Script the finance conversation so the monthly figure comes before the total price
- Rehearse objection handling for "is there a catch" and "what happens if I miss a payment"
- Give installers a one-page finance FAQ they can read from during a site visit
- Review call recordings monthly to check the script is actually being used
Protect your margin while running a 0% offer
0% to the customer doesn't mean free to run. Installers who skip this step end up subsidising every finance sale out of their own margin.
- Build the finance cost into your quote before you name a price, not after
- Compare instalment terms against your typical job margin before agreeing to longer plans
- Review how to protect profit margins when offering 0% finance before setting your standard terms
- Set a minimum order value for finance eligibility so small call-out jobs don't carry the same overhead as full installs
Advertise the offer without breaching ASA rules
Finance advertising in the UK is regulated. Get the representative example and eligibility wording wrong and you risk a complaint, not just a fine.
- State the number of instalments and that the offer is interest-free, not just "0% APR"
- Avoid implying guaranteed acceptance in any ad copy
- Keep terms and conditions one click away from every ad, not buried in a footer
- Have a compliance check built into your ad approval process, not left to whoever wrote the copy
Reduce declined applications and missed repayments
A finance option that gets declined at the point of sale is worse than no finance option — the customer feels rejected and the deal often collapses entirely.
- Set realistic eligibility expectations on your quote before the customer applies
- Use a platform that runs a soft eligibility check first, so declines happen quietly rather than publicly
- Follow guidance in how to reduce declined finance applications at checkout to tighten your pre-screening
- Keep a fallback payment option ready for anyone who doesn't pass the finance check

Comparing finance options for battery storage installers
| Option | Best for | Key limitation |
|---|---|---|
| Cash or bank transfer only | Installers with low deal volume and cash-confident customers | Loses quotes to competitors offering instalments |
| Interest-bearing retailer finance | Installers who don't mind customers paying more overall | Customer pays interest on top, weakens the pitch |
| In-house payment plan | Very small installers with a handful of repeat customers | No credit checking, installer carries all the default risk |
| 0% BNPL platform (PayItMonthly) | Installers who want instalments without chasing repayments | Requires customer to pass an eligibility check |
Common mistakes battery storage installers make
- Quoting the total price before mentioning finance. By the time the monthly figure comes up, the customer has already anchored on the big number and started hesitating.
- Treating solar and battery finance identically. Battery retrofits often sit on top of an existing solar loan or lease — stacking a second finance product without checking affordability invites a decline.
- Advertising "0% finance available" with no representative example. This is a common ASA flag in home improvement advertising and it's an easy fix.
- Skipping the eligibility check to close faster. A same-day sale on a customer who later misses repayments costs more in admin time than the deal was worth.
- Not training every team member on the finance script. One installer who can't explain the monthly cost undoes the work of a well-designed quote template.
FAQ
What is 0% finance for battery storage installers?
It's an interest-free instalment plan that lets a homeowner spread the cost of a battery storage install across monthly payments instead of paying the full invoice upfront. The installer gets paid in full through the finance provider while the customer repays over an agreed term.
Does offering 0% finance cost the installer money?
Yes, there's typically a fee to the merchant for offering interest-free terms, which is why building it into your quote before naming a price protects your margin. Skipping that step means the finance cost comes straight out of your job profit.
Is 0% finance better than in-house payment plans for battery storage jobs?
A 0% BNPL platform handles eligibility checking and repayment collection so the installer doesn't carry default risk, which in-house plans don't offer. In-house plans work only for very small installers with a handful of trusted repeat customers.
Can I advertise 0% finance for battery storage without falling foul of ASA rules?
Yes, but the ad must state the representative example, the number of instalments, and avoid implying guaranteed acceptance. Terms and conditions need to be easy to find, not buried below the fold.
How much does a battery storage system typically cost to install?
Pricing varies by system size, battery capacity and whether it's combined with a solar install, so installers should quote per job rather than rely on a fixed figure. What matters for the finance conversation is presenting the monthly cost clearly, whatever the total.
What happens if a customer misses a repayment on 0% finance?
The finance provider manages the collection process, not the installer, which is the main advantage of using a platform over an in-house plan. Installers should still set clear expectations at point of sale to reduce the chance of missed payments.
Do I need to run a credit check before offering battery storage finance?
Yes, a proper eligibility check is standard practice and protects both the installer and the customer from taking on unaffordable repayments. Skipping it to close a sale faster is one of the most common mistakes installers make.
Can battery storage installers offer finance on retrofit jobs, not just new installs?
Yes, retrofits are eligible for the same instalment structure as new installs, though installers should check whether the customer already has finance on an existing solar array before stacking a second plan.
One last thing
The installers who convert the most battery storage quotes into signed jobs in 2026 aren't the ones with the lowest price — they're the ones who can answer the finance question in the same breath as the quote, without picking up the phone to check. Build that into your script before you build it into your ads.
