How to Save When Shopping at BOXT

Does BOXT offer an NHS discount?
Yes, they currently offer a Blue Light & Defence Forces discount. Simply log into your Blue Light account or Defence Services account and search for BOXT promotions page to find your discount code.
How does BOXT work?
BOXT puts you in control. They let you buy a new product for your home, pick the installation date online, without the hassle of salespeople. Instead of sending a salesperson out to bother you at home, they get you to answer a few simple questions online. It's even easy to do on your phone or tablet. You'll be able to compare brand and prices to choose from, then you choose a convenient date to have one of their expert installers install it for you.
How does pay monthly work at BOXT?
If you choose to pay in monthly instalments, you'll apply for credit through their payment partner Divido to Novuna Consumer Finance. At checkout, just select pay monthly. They have a range of payment plans over 1, 2, 3, 5 and 10 years, including 0% APR available over 1 or 2 years. It’s 10.9% APR for the other plans. There is also the option to leave a deposit of up to 50% at the time of ordering, but you don’t have to on any of their plans. By leaving a deposit you will reduce your monthly payments and reduce the amount of interest you pay, on the interest-bearing plans. You then pay back the amount you borrow month by month, including any interest if applicable. The first payment is approximately 1 month after the installation but Novuna Consumer Finance will write to you and confirm all the details. If you would like to pay your finance off before the end of the agreement, contact the finance company directly who will give you a settlement figure and a length of time that figure is valid for.
What are the payment methods for BOXT?
Boxt accepts payments through VISA, Mastercard, and American Express.
Can I get a boiler cover from Boxt?
Not from Boxt, but you will as part of your manufacturer’s guarantee. Every new Boxt boiler comes with a manufacturer’s guarantee of up to 10 years. You don’t need to do anything to activate your guarantee – they will register your boiler with the manufacturer as part of their installation service.
