BOXT built its name on next-day boiler installation and has since widened into heat pumps, solar panels, home batteries and air conditioning, all sold through the same fixed online quote-and-book process rather than a home-visit sales pitch. Its referral scheme pays out on both sides once the job is actually done: £100 off your first order as the new customer, and a £100 shopping voucher for the friend who referred you, sent within about four weeks of your installation completing. EV chargers are the one product line excluded from the scheme. Because this covers a genuine home-improvement purchase rather than a quick sign-up, it's worth getting a couple of comparison quotes from local installers alongside BOXT's online price before booking — treat the referral discount as a bonus on a job you'd already decided to have done, not the deciding factor.
BOXT promo codes vs the referral link
BOXT does not publish separate public promo codes for shoppers to type in at checkout. The £100 discount is only available when you book through a valid referral link — that is the way to get money off a first installation. Open the link, get your online quote and complete the booking in the same session; the referral discount is applied to your order automatically.

Questions
BOXT referral FAQs
- Does the referral discount work on EV charger installs?
- No — BOXT excludes EV chargers from the referral scheme, so the £100 discount only applies to boiler, heat pump, air conditioning, battery or solar bookings.
- How quickly does my friend get their voucher?
- BOXT pays referrer vouchers within about 4 weeks of the referred job being installed, not at the point of booking.
- Is BOXT cheaper than a local installer?
- Not necessarily — BOXT's fixed online pricing is convenient, but it's still worth comparing a couple of quotes for a purchase this size before booking.
- Is there a BOXT promo code I can type in at checkout?
- No — BOXT does not publish separate public promo codes. The £100 off is only available through a referral link: open the link, get your quote and book in the same session, and the discount is applied to your order automatically.
- Can I use the BOXT referral with the NHS discount?
- BOXT does not guarantee that the £100 referral discount stacks with NHS or other brand discounts. Ask BOXT when you get your quote which reduction applies if you are eligible for more than one.
