Amazon UK has plenty of LEGO deals to choose from
Amazon Prime Big Deal Days is live on 6-7 October 2026, and UK LEGO buyers have considerably more choice than we found in the US sale. Rather than simply picking the ten largest percentage reductions, we have split our selections into two groups.
First are five headline sets where the discount makes some major or recent LEGO releases substantially cheaper. Then we have five sets with particularly large percentage reductions, including several at more than 30% below RRP.
These are only our selections from a much larger promotion. There are plenty of other LEGO sets reduced on Amazon UK, so it is worth checking the full sale if the set you want is not featured below. Prices and stock can also change during the event, so always check the current Amazon price before buying.
5 headline LEGO sets worth checking
1. LEGO Pokémon 72153 Venusaur, Charizard and Blastoise - £492.89
RRP: £579.99 | Amazon price: £492.89 | Saving: £87.10 | Discount: 15%
One of the most eye-catching reductions is on LEGO Pokémon 72153 Venusaur, Charizard and Blastoise. This enormous 6,838-piece set brings together the final evolutions of the three original Kanto partner Pokémon, with posable figures and connected beach, jungle and volcano display environments.
A 15% discount may not be the largest percentage in the sale, but on a £579.99 flagship it removes £87.10 from the price. For Pokémon fans considering one of LEGO's biggest new display sets, getting below £500 makes a meaningful difference.
2. LEGO Icons 10333 The Lord of the Rings: Barad-dûr - £339.99
RRP: £399.99 | Amazon price: £339.99 | Saving: £60.00 | Discount: 15%
Barad-dûr is one of LEGO Icons' major Lord of the Rings display sets, with 5,471 pieces, a tower standing more than 80 cm high and 10 LEGO minifigures including Sauron, Mouth of Sauron, Frodo, Sam and Gollum.
Amazon's £339.99 price saves £60 against the £399.99 RRP. That is a useful reduction on a premium licensed set that requires a substantial outlay even when discounted, and makes this a good time for Lord of the Rings fans who were already considering adding Barad-dûr to their collection.
3. LEGO Icons 10356 Star Trek: U.S.S. Enterprise NCC-1701-D - £296.99
RRP: £349.99 | Amazon price: £296.99 | Saving: £53.00 | Discount: 15%
The LEGO Icons U.S.S. Enterprise NCC-1701-D is another major licensed adult set included in the sale. The 3,600-piece model features the detachable command saucer, warp nacelles, shuttlebay and display stand, alongside nine Star Trek: The Next Generation LEGO minifigures.
At £296.99, the deal brings the Enterprise below £300 and saves £53 against RRP. For Star Trek fans attracted to the model but put off by its £349.99 launch price, that is a much more appealing entry point.
4. LEGO Marvel 76354 S.H.I.E.L.D. Helicarrier - £259.99
RRP: £329.99 | Amazon price: £259.99 | Saving: £70.00 | Discount: 21%
The 3,057-piece S.H.I.E.L.D. Helicarrier recreates the Avengers vehicle as a large adult display model, with detailed runways, engines, aircraft and interior areas. Six LEGO minifigures are included: Winter Soldier, Captain America, Phil Coulson, Maria Hill, Hawkeye and Nick Fury.
This is a stronger percentage reduction than the first three headline sets. Amazon has cut £70 from the £329.99 RRP, bringing the Helicarrier down to £259.99. A saving of more than 20% is significant on a recently released premium Marvel set.
5. LEGO Technic 42215 Volvo EC500 Hybrid Excavator - £242.19
RRP: £349.99 | Amazon price: £242.19 | Saving: £107.80 | Discount: 31%
The largest cash saving in our headline group is on the LEGO Technic Volvo EC500 Hybrid Excavator. This 2,359-piece adult model includes a motor and gearbox controlling four functions, interchangeable hammer and shovel tools, moving tracks and a rotating excavator body.
The price falls from £349.99 to £242.19 - a saving of £107.80 and just over 30%. That combination of a three-figure cash saving and a substantial percentage reduction makes the Volvo one of the standout large-set deals we have seen in the UK sale.
5 LEGO sets with some of the biggest discounts
If the size of the discount is the priority, these five deals deserve particular attention. Each is around 29% or more below RRP, with three exceeding 35% off.
1. LEGO Harry Potter 76454 Hogwarts Castle: The Main Tower - £142.99
RRP: £229.99 | Amazon price: £142.99 | Saving: £87.00 | Discount: 38%
The biggest percentage reduction among our ten selections is on Hogwarts Castle: The Main Tower. The 2,135-piece Harry Potter set builds the largest minifigure-scale version of the Main Tower yet and includes 12 LEGO minifigures plus Fluffy, Hedwig and Fawkes.
At £142.99 rather than £229.99, buyers save £87 - approximately 38%. Getting a large Hogwarts set with this much minifigure content for well below £150 makes this one of the clearest value deals in the sale.
2. LEGO City 60508 Police Train Heist - £113.89
RRP: £179.99 | Amazon price: £113.89 | Saving: £66.10 | Discount: 37%
LEGO City Police Train Heist combines a Powered Up motorised locomotive, three flatcars, track, helicopter, rally car and six LEGO minifigures in a 1,313-piece playset.
The Amazon price of £113.89 represents a £66.10 saving, or roughly 37% off RRP. Powered LEGO train sets are rarely cheap, so bringing a complete motorised train package much closer to £100 makes this a particularly strong family or Christmas purchase.
3. LEGO Architecture 21063 Neuschwanstein Castle - £152.99
RRP: £239.99 | Amazon price: £152.99 | Saving: £87.00 | Discount: 36%
The 3,455-piece Neuschwanstein Castle is a substantial LEGO Architecture display model recreating the famous Bavarian landmark, complete with detailed towers, courtyard and seasonal foliage that can be configured for summer or autumn.
Amazon has reduced it by £87 to £152.99, approximately 36% below its £239.99 RRP. For an adult Architecture set of this scale, that is a major reduction and puts the cost at roughly £150 rather than £240.
4. LEGO Star Wars 75417 UCS AT-ST Walker - £120.99
RRP: £179.99 | Amazon price: £120.99 | Saving: £59.00 | Discount: 33%
The Ultimate Collector Series AT-ST Walker is a 1,513-piece adult Star Wars display model with an opening two-person cockpit, rotating head, adjustable laser cannons, information plaque and exclusive-style AT-ST Driver LEGO minifigure detailing.
At £120.99, the set is £59 below its £179.99 RRP - around 33% off. For Star Wars collectors, getting a UCS-branded display set this close to £120 makes it one of the more notable licensed deals in the event.
5. LEGO Art 31220 Claude Monet - Bridge over a Pond of Water Lilies - £127.29
RRP: £179.99 | Amazon price: £127.29 | Saving: £52.70 | Discount: 29%
LEGO Art's 3,179-piece interpretation of Monet's Bridge over a Pond of Water Lilies turns the famous painting into a textured brick-built wall display. The set was created in collaboration with The Metropolitan Museum of Art.
The £127.29 Amazon price saves £52.70 against the £179.99 RRP, a reduction of just over 29%. It is a strong option for adult builders looking for LEGO home decor rather than another vehicle or character-based display model.
Don't stop at these ten LEGO deals
The UK Prime Big Deal Days LEGO selection is broad enough that these ten sets should be treated as a starting point, not an exhaustive list. Our headline picks highlight some of the more interesting premium and recent sets, while the second group focuses on unusually deep percentage reductions.
If none of these is the set you are looking for, check the full Amazon UK LEGO sale. With a much wider range of discounted products available, there may be better choices for a particular theme, budget or recipient.
Prime Big Deal Days runs through 7 October 2026. Prices and availability can move during the event, so verify the live price before purchasing.
