Valid Small Pet Select UK discount codes for September 2026

Applying a Small Pet Select UK discount code is pretty straightforward. Here's how we do it:

1. Find a code on LatestDeals – the verified ones are always at the top.
2. Click the orange 'see code' button and copy the code that pops up.
3. A new tab opens and takes you straight to Small Pet Select UK.
4. Shop for your hay, bedding, pellets or treats and add them to your basket.
5. When you're ready to pay, look for the 'discount code' box at checkout – it's usually near the order summary.
6. Paste your code in there and hit 'apply'.
7. You should see the discount come off your total straight away – then just finish the order as normal.

One thing we've learned the hard way: codes are often case-sensitive, so copy them exactly. And if it doesn't work, check you haven't got two codes in the basket – only one is allowed per order.

So you've found a code, tried to apply it, and nothing happened. Don't panic – this happens more often than you'd think. Here's what to check:

1. See if the code has an expiry date. We only list codes that are meant to work, but sometimes they expire sooner than expected.
2. Look at the fine print – some codes only work on certain products, or might be excluded from Auto-Ship orders, value-choice hay, or already discounted items.
3. Make sure you're only using one code. Small Pet Select UK doesn't let you stack discounts, so if you've got another promo or a reward voucher applied, that could be blocking it.
4. Check your basket total. Free delivery kicks in over £39.99, but some codes require a minimum spend. If you're under that, the code might not apply.
5. Try clearing your browser cache or using an incognito window – sounds silly, but it works sometimes.
6. If all else fails, drop their customer service a message. In our experience, they're pretty good at sorting things out.

Unfortunately, no. Small Pet Select UK's policy is pretty clear – only one discount or promo code per order. So you can't stack a voucher with a rewards redemption, or use two different codes on the same basket. That applies to Auto-Ship orders too – those are already discounted, so they're excluded from extra codes, rewards points, military discounts, and store credits. If you're trying to save more, your best bet is to look for the code that gives the biggest percentage off, or wait for their Thrifty Thursday deals – that's when we see the best offers pop up.

Yes, but it's not quite what you might expect. The verified first-order discount is for their Auto-Ship & Save subscription – you get 30% off your first subscription order if you use the code AUTOSHIP30 at checkout. That's only for the first delivery, not a one-time order. So if you're just buying a one-off bag of hay, you won't get anything off with that code. But if you're planning to set up regular deliveries, it's a decent saving. Also, they have a referral scheme – refer a friend and they get £10 off their first order of £40, and you get £10 in points for each successful referral. So that's another way to knock a bit off if you know someone else who keeps small pets.

Yes – free UK Mainland delivery is available on orders over £39.99, after any discounts and before tax. If your basket comes in under that, there's a flat £4.95 delivery charge for Mainland UK. Not bad, really, especially if you're stocking up on hay and bedding. Just remember, it's for Mainland UK only – if you're in the Highlands, islands, or Northern Ireland, you might have extra charges or customs fees depending on where you are. And they don't deliver to PO boxes, which is worth knowing if you're used to having parcels left at the post office.

Small Pet Select UK uses UPS, DPD, and Royal Mail for their deliveries. Most orders placed before 4 pm GMT get shipped out the same business day, and the average delivery time is about 1.9 business days – so it's pretty quick. There's no special next-day option listed, but given how fast they are, you probably won't need one. The cost is a flat £4.95 for Mainland UK orders under £39.99, and it's free over that. As we said, non-mainland UK might have extra charges. Also, they don't ship to PO boxes, so make sure you've got a physical address for delivery.

Their returns policy is fairly straightforward, but there are a few things to watch. You have 14 days from receiving your order to report any issues – if you do that, they'll usually offer a replacement or store credit. That's the easy part. If you want to return something after 14 days, they might still accept it, but it's at their discretion, and you'll have to cover the return postage yourself. So if something arrives damaged or wrong, make sure you get in touch quickly. We'd also suggest keeping the packaging and any paperwork until you're sure everything's fine – it makes any claims much easier.

No, you can't. Coupon codes, rewards points, military discounts, and store credits are all excluded from Auto-Ship & Save orders. That's because the Auto-Ship items are already discounted – you're getting a lower price for signing up for regular deliveries. So if you're trying to use a code on an Auto-Ship order, it won't work. If you want to use a discount code, you'll need to make a one-time purchase instead. It's a bit annoying if you're already on Auto-Ship, but at least you know you're getting a decent deal on those orders anyway. And if you're new to Auto-Ship, don't forget the AUTOSHIP30 code for 30% off your first subscription order – that's one of the best savings we've seen.
