BOXT Referral Code: £100 Off — What Actually Qualifies

BOXT's referral scheme is straightforward on the surface — £100 off your first order, £100 back to the friend who referred you — but it's tied to a home-improvement purchase rather than a quick sign-up, which means the timing and the qualifying rules matter more than they would for a bank or an app. Here's what actually counts.

What qualifies for the £100 discount

The referral discount applies to boiler, heat pump, air conditioning, home battery and solar installations booked through boxt.co.uk. Any of those product lines qualify as your first order, and there's no cap on how many friends can refer you to the scheme or vice versa.

The one exclusion: EV chargers

BOXT sells EV chargers alongside its other product lines, but they're specifically excluded from the referral scheme. If you're getting a charger installed, the £100 discount won't apply to that order — it only counts for boiler, heat pump, air conditioning, battery or solar bookings. Worth checking before you book if a charger is the only thing on your list.

When the discount actually applies

Unlike a lot of referral schemes that make you wait for a purchase to complete before crediting anything, BOXT applies your £100 discount automatically at the point of booking, as long as you went through a valid referral link. You don't need to wait for the installation to happen to see the reduced price — that part is immediate.

When your friend gets their £100 voucher

The referrer's side works differently: their £100 shopping voucher is only issued once your installation is actually completed, and it typically takes around four weeks to arrive after that. If you're the one who shared the link, don't expect the voucher the moment your friend books — it's tied to the job being finished, not the order being placed.

Who can send a valid referral link

Only someone who's already had a qualifying BOXT installation can generate a working referral link — you can't refer a friend before your own job has gone ahead. If a link isn't working, that's the most likely reason: the referrer hasn't completed their own installation yet.

Promo codes vs the referral link

BOXT does not publish separate public promo codes alongside its refer-a-friend scheme. The £100 off for new customers is only available when you book through a valid referral link — there is nothing extra to type at checkout. Use the link on this page, get your quote and complete the booking in the same session, and the referral discount is applied automatically.

Should you actually book with BOXT?

£100 off is a genuine discount, but it's a bonus on a purchase that can run into thousands of pounds — not a reason to skip comparison shopping. BOXT's fixed online pricing is convenient and its next-day fitting is a real advantage if you've got a broken boiler, but it's still worth getting a quote or two from local installers before you commit, the same as you would for any job this size.
