A quick note from us at LatestDeals: Sons codes usually apply to service or plan fees such as consultation, aftercare, delivery, or account access. They normally do not cover the medication itself, and single products or cosmetics are often excluded too.

If your Sons code isn’t working, try these checks first.

1. Make sure you copied it exactly, with no extra spaces.
2. Check that the offer matches your order, because some Sons promo codes only work on selected plans.
3. Sons allows only one promotional code per order, so you cannot stack them.
4. Some discounts exclude single products, cosmetics, and the medication cost itself.
5. If it is a referral offer, it will not work on 12-month plans or single products.

If it still will not apply, the code may have expired or been removed. That happens. We usually suggest trying another Sons voucher from LatestDeals, because the better ones do disappear quickly.

Yes. Sons offers free UK delivery on orders over £40.

If your order is under £40, standard Royal Mail delivery costs £2.99 and usually takes 3 to 5 working days. There is also a 48-hour tracked option for £3.99.

Sons ships to the UK and Ireland only. Royal Mail delivers Monday to Saturday. Subscription orders are sent automatically, so you do not need to place them each time.

Yes, Sons has a couple of offers for new customers.

New customers can get 40% off selected 6-month plans plus a free Welcome Pack, which is a starter bundle worth about £75. The pack includes items such as a wash bag, travel bottles, biotin, and a pill case.

There is also code SONS30, which gives 30% off a first order on the Core Plan.

We think it is worth checking which offer works best for the plan you actually want, because the best saving depends on what is in your basket.

No. Sons allows only one promotional code per order, so you cannot combine or stack codes.

If you have a Sons discount code and a referral offer, you will need to choose whichever gives you the better saving at checkout.

Yes. Sons offers 30% off plus free hair care for students through Student Beans.

You will need to verify your student status on the Student Beans platform before the discount is applied. We always suggest sorting that out before checkout, just to avoid a bit of back and forth later.

Sons accepts returns within 14 days of delivery for non-medicinal products, as long as they are unopened and in their original packaging.

Prescription and medicinal products cannot be returned by law, so those are non-returnable.

For eligible returns, the customer pays the return postage. It is not the most generous policy, but it is pretty standard for this kind of product.
