A GBK discount code everyone wanted
We don't often see a vegan burger deal get this much attention, but this one did. 20% off the whole plant-based menu, burgers and sides included. Our members wouldn't stop talking about it, especially the ones who usually skip the meat. It didn't last long, which didn't surprise us. If it ever comes back, we'll be the first to let you know on LatestDeals.

GBK: Check for burger savings before you order
Before you order from Gourmet Burger Kitchen, it's worth a quick look for a discount code or voucher. GBK does burgers, sides, shakes, and desserts, so a small saving adds up, especially when you're feeding two or more.
At LatestDeals, we always check for offers that work on the whole meal, not just one item. That's where the real value is. If you're planning a bigger order, see if a code can trim the total instead of giving you a tiny percentage off a single burger. Sounds obvious, but you'd be surprised how often people miss it.
Find a code first, then compare your basket total with and without it. Do that before you add the extras like shakes or desserts. That way you'll know exactly what the saving is worth. We've seen people skip this step and then wonder why they paid full price. Don't be that person.

Money saving tips at Researching gbk.co.uk retailer
Check Codes First
Before you hit that order button at GBK, have a quick look for a discount code or voucher. Honestly, it's most worth it if you're going big – burger, sides, shake, dessert, all that stuff adds up faster than you'd think. Our rule of thumb: find the saving first, then build the basket. Saves you a bit of faff later.
Use Voucher
Found a GBK voucher? Great, use it on the whole order, not just one item. We've found that getting money off the whole meal feels way better than scraping a bit off a single burger. And honestly, why leave money on the table when the whole table's already hungry?
Look For Offers
Keep an eye out for GBK offers tied to set meals or limited-time deals. Restaurants love a quick burst of savings, and those can be a lifesaver when you're ordering for two or more. Our community usually spots them early, so it's worth a quick check before you pay full price.
Go Takeaway
Ordering for collection can save you a few quid compared to delivery – you dodge the extra fees. We always say to compare both options if you're nearby anyway. A short walk or drive might knock a couple of pounds off the final bill. Not glamorous, but it works.
Frequently asked questions about Researching gbk.co.uk retailer
How do I use/apply a GBK discount code?
Head over to LatestDeals and grab the GBK code that matches what you're ordering. Click the orange 'see code' button and copy the code that pops up. A new tab should take you straight to the GBK site - if it doesn't, just go to gbk.co.uk yourself.
Add whatever you're after to the basket - burgers, sides, shakes, whatever. Honestly, we'd add everything first before you even think about the code.
When you're ready to pay, hit checkout and find the box marked something like 'Promo code' or 'Discount code'. It usually sits near the payment section. Paste your code in, hit 'Apply', and the discount should come off right away so you can see it before paying.
Finish the order and that's it. Few quid off a decent meal - not bad at all.
What can I do if my GBK code isn't working?
First, check the code hasn't expired - some deals are time-limited. Then look at the terms: is there a minimum spend, or does it only apply to certain items like burgers rather than sides?
Try typing the code in manually instead of pasting. Copy-paste hidden spaces and stray characters cause more fails than you'd think. Also double-check the URL - it needs to be gbk.co.uk, not a third-party delivery site. And if another code is already applied to your basket, that can block a new one, since usually only one works per order.
If nothing's working, clear the basket and start again. A quick refresh sorts out glitches more often than you'd expect. Still stuck? GBK's customer service is genuinely decent at sorting these things out - we've seen them fix codes quickly.
Can I use more than one GBK voucher code on the same order?
From what we've seen, GBK - like most places - only allows one promo code per order. So if you've got two, say one for 10% off and another for free delivery, you'll probably have to pick whichever saves you more.
Some codes apply automatically without you entering anything, but if you want to test stacking, pop them in one at a time and see what sticks. The fine print on each code usually spells out the rules, and GBK's site does too.
Our rule of thumb: use the one that takes the most off your total.
Does GBK offer delivery or takeaway options?
Yep, GBK counts as a restaurant and takeaway, so delivery or collection are both on the table. How you order depends on your area - you can go through GBK's site directly, or they might be listed on Deliveroo or Uber Eats.
Delivery fees and minimum spends vary by location. One catch worth knowing: some discount codes only work on GBK's own site or app, not third-party platforms. So if you're using a code from us, order through gbk.co.uk or their app to make sure it applies.
Click and collect is often the cheaper route - no delivery fees to worry about, and your food's ready when you get there.

I'm Tamires, a content researcher at LatestDeals, and I’ve been helping members save money since 2020. I check vouchers and retailer details carefully so we only share info that feels useful and real. One thing I’d always do at GBK is go for collection if you can, because it usually avoids delivery fees and keeps the final price a bit more sensible. That small swap can make a proper difference when you’re ordering burgers, sides and a shake. Away from LatestDeals, I’m usually sipping coffee, out on a walk, or thinking about my next pastry fix, which is a bit cheeky really.
