UK voucher codes and discount codes

If you searched for a voucher code, discount code, or promo code for one of the brands I cover, here’s the reality: most of them don’t run public codes at all. A few run occasional promotions. A small number, mostly subscription and hardware brands, run near-permanent percentage-off campaigns.

Referral Plug isn’t a voucher code aggregator. I cover 28 UK brands I use personally, and for almost all of them the refer-a-friend reward is the real sign-up saving, not a code you paste at checkout. This page sorts every brand into one of three clear buckets, each with a link to the full breakdown and the date I last checked it.

Brands that don't run public discount codes

For these brands, no public voucher or promo code exists. The refer-a-friend reward is the only sign-up saving, and it's often worth more than a typical checkout discount.

Brands that run occasional promotions

These brands run the odd promotion or welcome offer, but nothing you paste at checkout day to day. The refer-a-friend reward is the standard, reliable saving.

Brands where public discount codes are the standard

These brands really do run public discounts, so the search intent is legitimate. I describe the structure and a typical range; the brand's own site stays canonical for the live number.

How to evaluate a UK voucher code site

Voucher code sites are not all the same, and the difference matters. Some are auto-scraped aggregators that list thousands of codes with no human checking whether they still work, so a large share are expired or simply don’t apply at checkout. Others are editorial or community-driven, where a smaller set of codes is actually verified.

When you land on a voucher site, the questions worth asking are: does anyone here actually test these codes, when was this page last updated, and is the affiliate relationship disclosed? A long list of codes is easy to generate; a short list of working ones takes effort.

Why referral codes often beat voucher codes

For the brands on this page, a refer-a-friend reward is usually better value than a public discount code would be. A typical checkout voucher might take 10 or 15% off a single purchase. A refer-a-friend reward is often a flat cash amount, free months, or bill credit that lands once regardless of how much you spend, and it rewards the person who referred you too.

The difference between a referral code and a voucher code is worth understanding before you sign up. You can also compare every UK referral code I track side by side.

Voucher and discount code FAQ

Are UK voucher code sites trustworthy?

It depends on the site. Auto-scraped aggregators tend to carry a high share of expired or non-working codes, because no human verifies them before they go live. Editorial and community-driven sites, where codes are actually checked, are generally more reliable. The real test is whether a site shows when each code was last verified and whether it discloses its affiliate relationships. For the brands I cover, most don't issue public codes at all, so the most reliable saving is the refer-a-friend reward, not a code from a third-party site.

What is the difference between a voucher code and a referral code?

A voucher or promo code is a public discount that anyone can use at checkout, and it usually benefits only the buyer. A referral code is tied to a specific existing customer and rewards both sides when a new customer signs up. For most brands I cover there is no public voucher code; the refer-a-friend code or link is the only way to get a sign-up reward.

Which UK brands actually run public discount codes?

Among the brands I cover, the ones that genuinely run public discounts are Surfshark (near-permanent percentage-off VPN campaigns), Ledger (seasonal hardware sales), and Affordable Mobiles (rotating contract deals). For these, the referral reward applies on top of whatever discount is live. Every other brand I cover runs no public code, with one exception: Tide, where a time-boxed promo advertised on partner sites can pay more than the referral code if your business can park £5,000 in a Tide savings account. Everywhere else, the refer-a-friend reward is the saving.

Is Referral Plug a voucher code site?

No. Referral Plug is an editorial site covering UK refer-a-friend schemes for brands I use personally, and it doesn't scrape or list public discount codes. For checkout discount codes at high-street retailers, a cashback or editorial deals site is usually the better place to look. For sign-up rewards on the brands covered here, the refer-a-friend reward is what gets verified and tracked.

Do referral codes expire like voucher codes?

Refer-a-friend schemes can change or pause, but they tend to be far more stable than public voucher codes, which often expire within days. Every brand on this page shows its last-checked date, and I re-verify the schemes regularly. If a scheme is paused, I flag it.
