Home Battery Sales Pitches: Red Flags and What to Check Before You Sign
- Citizens Advice says it is better to find an installer yourself than to deal with a firm that cold calls.
- The RECC Consumer Code bans pressure tactics such as limited availability claims and visits over two hours.
- Both Citizens Advice and RECC say to get at least three quotes and pay no more than 25% up front.
- Check the firm on the MCS website and the TrustMark register, and ask who insures your deposit.
- Anything promised out loud should be in the written quote and contract.
A good home battery sale survives a day of thinking about it. If the pitch only works when you sign tonight, that tells you more than any brochure. This guide lists the warning signs, and the checks that take an hour and can protect thousands of pounds.
Red flags in how the pitch is made
Citizens Advice advises avoiding firms that cold call and finding an installer yourself. Its December 2023 report on low carbon home improvements also describes pressure selling, including a trader who pushed a customer to proceed because he had travelled a long way. A battery is not an emergency purchase, so urgency is a warning in itself.
The RECC Consumer Code, which MCS installers join, lists tactics its members must not use. These are good red flags to carry into any conversation:
- Staying in your home for more than two hours without a recorded reason.
- An inflated price followed by a discount, or discounts for signing the same day.
- Holding back the price until the end of the visit.
- Claims that stock or an offer is about to run out.
- Unrealistic claims about future energy prices or your savings.
A simple rule
Never sign on the first visit or call. Ask for the written quote, the Consumer Code name and the deposit insurance details, then check them yourself before replying.
What about a temporary subsidy?
Be wary of any claim that a grant or offer will vanish unless you sign now. We did not find a rule written specifically about subsidy deadline claims, but the limited availability tactic above is banned by the Code, and Trading Standards guidance says traders should not make misleading claims. If a scheme is real, you can check it yourself on GOV.UK without the salesperson in the room.
The Code also says that where a grant is essential to the deal and is not awarded, you cannot be held to the contract and the deposit and advance payments must be refunded in full. Ask for that to be in writing.
Checks on the firm
For batteries, Citizens Advice points to MCS. The Energy Saving Trust adds TrustMark, and notes that MCS installers must also belong to a consumer code: RECC, HIES or the Glass and Glazing Federation code. Check the firm yourself on the MCS website rather than trusting a badge on a leaflet. Be careful with look-alike sites, because not every site using the TrustMark name is the official one.
Ask four things: is the firm certified for batteries, which Consumer Code does it belong to, who contracts with you, and what insurance backs your deposit. Under the RECC Code the contract must be with one business that is both MCS certified and a Code member. MCS also says installers must offer an Insurance Backed Guarantee that pays out if the installer stops trading.
Checks on the paperwork and your rights
Get the quote in writing, and get at least three, as both Citizens Advice and RECC recommend. Under the Code the written terms cover the price with the correct VAT rate, cancellation rights, payment timing, guarantees and after-sales support. For what a certified installer handles, see our guide to DIY or professional installation.
On payment, RECC says never to pay more than 25% of the contract price up front, and the Code allows deposits and advance payments combined to reach no more than 60% of the estimated total. Citizens Advice reports that deposit insurance can be time limited, so ask how long the cover lasts and compare it with your installation date.
On cancelling, the Code gives you 14 days if you sign at home or at a distance, counted from delivery of the last item of goods, and the firm must give you written notice of this right. GOV.UK guidance says that for services the period starts the day after the contract is made. Work may only start earlier with your express written consent, and then you pay for work done if you cancel. The Energy Saving Trust page mentions a seven-day cooling-off period, so we followed the Code and GOV.UK wording; confirm the exact period in your own contract.
Common questions
Can I cancel a home battery contract I signed at home?
Under the RECC Code you can cancel without penalty within 14 days of delivery of the last item of goods if you signed at home or at a distance. Check the period and the notice form in your own contract.
Is it safe to pay a deposit?
RECC says never to pay more than 25% up front and to check that the amount is insured. Citizens Advice found deposit protection can be time limited, so ask how long it lasts.
Does MCS certification guarantee a good installation?
No scheme guarantees that. It does mean the installer has been assessed and must use a consumer code, which gives you a complaints route if something goes wrong.
Should I ever buy from a cold call?
Citizens Advice advises finding an installer yourself. If a call interests you, treat it as a prompt to research, not a deal to accept.
