How to apply a smol promo code

A discount code only works on orders placed through the website, because discounts are linked to an account. You'll need to register before you can check out, and you must be 18 or over. Once you've copied your code from this page, the process usually takes a few minutes:

• Choose the product, free trial or bundle you want on the website and start your order.
• Create your account and confirm the details of your plan, such as how often you want deliveries.
• At the payment details step, paste your promo code into the discount code box.
• Check the order summary and make sure the discount appears before you confirm your payment.

The last check matters most, because it is your final chance to correct anything before you're charged. If the saving isn't shown straight away, it doesn't necessarily mean the code has failed. The company says that in this case the discount is applied automatically to your next regular order, and you receive an email to confirm it. Keep that email until you see the reduction on your next charge.

If you're already a customer, the process is simpler still. Discounts you've earned, including referral credit, come off your next scheduled charge without you having to enter anything.

Why your smol coupon code isn't working

When discount codes are rejected, the cause is usually one of the conditions attached to them rather than a problem with the checkout. Working through them in order tends to find the answer quickly.

The product. Many codes are linked to a specific product, bundle or plan, so a code for laundry capsules won't necessarily work on a bundle. The same applies to items already sold at a first-order price or inside a discounted bundle: these are offers in their own right, so an extra code may not reduce them further. If an offer mentions a minimum spend or a single product line, your basket needs to match it.

The code itself. It may have expired, or a space or wrong character may have slipped in while typing. Copying and pasting the code avoids most of these errors.

Eligibility. New-customer offers are limited to one per household. smol may treat you as an existing customer if your card, delivery address or household has already been used for a smol account. For example, if someone at your address has already used a welcome offer, a new account in your name will usually be refused the same type of code.

Combining offers. Unless the terms say otherwise, a voucher code won't stack with another offer, with account credit or with the referral bundle. Referral credit isn't a coupon code either. There is nothing to type in, because it comes off your next charge automatically.

Sometimes the code is valid but the payment is the issue. The website accepts card payments only, as listed in the payment information in its help centre, so a declined payment method can look like a failed discount.

smol offers you don't need a code for

Some of the best-value smol deals are applied automatically. For new customers, they are often the simplest discount, because there is nothing to enter and nothing to expire at the checkout.

The free trials let you test laundry capsules (bio, non-bio or fragrance-free) or dishwasher tablets with 9 free washes. You only pay postage, which is shown at checkout. Trying a product this way before your first full pack is the lowest-cost way to find out whether it suits your machine and your household.

On several product pages, the first-order price appears next to the crossed-out full price. The saving is already built in, so no promotion code is needed.

Bundles work the same way, with the discount applied to the whole set rather than item by item. Larger bundles cover the kitchen, the laundry or the whole home, which can make more sense if you want to replace several products at once.

All of these offers start a regular plan, so it helps to know how plans work before you order.

How smol plans work and how to keep costs down

Ordering from smol sets up a plan rather than a one-off purchase. After a free trial, your first full pack is processed 14 days later. Once an introductory offer has been used, later orders are charged at the regular price. If you have a larger drum or very hard water and use two capsules per load, as the website suggests in those cases, the cost per wash doubles.

From the plans section of your account you can move your next charge date, change how often deliveries arrive and choose how many packs you receive each time. Matching the schedule to your real usage is the simplest way to avoid paying for stock you don't need. As a guide, if you run five loads a week with one capsule each, a 24-capsule pack lasts just under five weeks. A shorter frequency than that means packs will build up in the cupboard.

Changes to payment details and cancellations need to be made at least 24 hours before the next charge. Otherwise, that order goes ahead as planned.

How to get free delivery 

You do not need a smol voucher code to qualify for free delivery. Orders are dispatched via a tracked postal service, which incurs a standard delivery charge but becomes completely free once your basket reaches a specific minimum spend.

If you manage multiple subscription plans, utilising the grouped delivery feature allows you to combine orders scheduled around the same time into a single shipment. By doing this, you only pay a single delivery charge rather than multiple separate fees, significantly increasing your chances of reaching the free-delivery threshold. For instance, an individual refill order might fall short of the minimum spend, but consolidating it with a laundry replenishment can push the total value over the line, entirely removing the shipping cost. You can easily enable automatic grouping within your account settings or manually combine shipments whenever it is convenient. Grouping remains completely optional; however, items dispatched separately will each incur their own standard delivery fee.

When you use a discount on the same order, check the final total in the order summary, since that is where you can see whether the delivery fee still applies.

Refer a friend and other ways to get smol discounts

For existing customers, the referral scheme is the most straightforward way to earn a discount. You share the personal link from your account with a friend who hasn't been a customer before. They can buy the smol Friends Bundle. You receive a credit towards your next order, which is taken off automatically, or you can donate it to smol's Suds in Schools scheme. You can't refer yourself or anyone at your address, the scheme can't be combined with other offers, and unused credit expires. It makes sense to let it go towards an order you were already planning.

The company also shares promotional codes with customers by email. You can join the emails through the sign-up form on its website or when you create an account. There is no fixed welcome discount for signing up, and you can unsubscribe at any time. At the time of writing, smol doesn't advertise a loyalty card or points scheme, so referral credit is the closest equivalent.

Does smol have sales?

The website doesn't publish a calendar of sales events. Promotions tend to appear as reduced prices on product and bundle pages, or arrive by email. Like most offers, they are time-limited and can end without notice, so planning a purchase around a specific date is difficult.

Because introductory offers are limited to one per household, the timing that matters most is usually your first order. After that, emails and account credits are where discounts are more likely to appear. The quickest way to check what is running at any moment is the offers list at the top of this page, alongside the product pages on smol's website.

Returns and refunds on discounted orders

If your first delivery isn't right for you, the money-back guarantee lets you claim a refund within 10 days of it arriving. To claim, email smol from the address linked to your account, explain why, and send back what is left of the pack. Return postage is at your cost, and the guarantee is limited to one claim per household.

Refunds are based on what you actually paid, so any discount or credit used on the order is taken into account. For bundles, each item is refunded at its full price minus the discount applied to the order, and free gifts aren't refunded. In practice, if you bought a bundle at an introductory price, the refund reflects that lower price, not the full list price.

For other returns, contact smol within 7 working days of delivery, with the pack still unopened.

Quick recap: saving more at smol

Paste your code at the payment step and check that it appears in the order summary before paying. If you're new, start with a free trial or a bundle, and keep in mind that introductory offers can be used once per household. To secure free delivery, ensure your total order value stays at or above the required spending threshold, or simply group multiple plans together. For the most cost-effective subscription, set your delivery frequency to match your actual household usage. If you ever need to pause or adjust your plan, ensure you apply those changes well in advance of your next scheduled billing date to avoid unwanted charges.

Since introductory offers are available once per household, your first order is the one worth planning. If you already know you'll use several smol products, a larger bundle usually gets more value out of that one-time discount than a single trial, provided you'll actually use everything in it.

Different types of benefit can work together, even when two codes can't. An introductory price, the free-delivery threshold and grouped delivery can all apply to the same box. Likewise, referral credit can come off an order that is also grouped with your other plans. What you shouldn't expect is two discount codes, or a code plus the referral bundle, on one order.

FAQ

Is there a smol NHS, Blue Light or over-60s discount?

At the time of writing, the company doesn't advertise a discount for NHS staff, Blue Light Card members or over-60s on its website. Offers open to everyone, such as free trials, bundles and referral credit, are shown in the list at the top of this page.

Does the website offer a student discount?

There is no student discount on the website at the time of writing. New offers, including any student deals, are added to the list above when they become available.

Can I use a discount code on packs bought in a supermarket?

No. Discounts and credits are redeemed through a smol account on its website, so they don't apply to packs bought in a supermarket. 

Can I pay with vouchers or gift cards from other shops?

No. The help centre lists Visa, Mastercard and American Express debit and credit cards as the accepted payment methods. It says PayPal, Apple Pay and prepaid cards aren't accepted at the moment, so vouchers and gift cards from other retailers can't be used either.

Does the company sell gift cards?

smol doesn't list gift cards on its website at the time of writing. Gift cards you may find online under the name Smol usually belong to unrelated brands with a similar name.

Do I need to be 18 to order?

Yes. You need an account to buy from smol, and you must be at least 18 to register.

Can I cancel the free trial before I'm charged?

Yes. During the trial period, email smol from the address linked to your account. Once you receive the email saying your first full pack will be processed in 3 days, you can also cancel online. In either case, allow at least 24 hours before the charge date.

Where does smol deliver?

The company delivers nationwide, including the Highlands and Islands, the Isle of Man, the Isles of Scilly and the Channel Islands.

How long does a delivery take?

Orders are usually packed and dispatched within 1 to 2 working days, then travel on a 48-hour tracked service.

What happens to my referral credit if I close my account?

It is removed as soon as the account is closed. Credit also expires if you don't use it, and it can't be exchanged for cash, so the safest option is to spend it on your next order.
