Every LEGO Set Retiring at the End of 2026: The Full UK List (And What to Grab First)

Every December, LEGO quietly closes the book on hundreds of sets, and 2026 is no exception. Once a set's page moves to LEGO.com's 'Retiring Soon' category, it means the exact model will not be reordered — when LEGO.com and UK retailers sell through what's left, that specific box is gone for good (short of paying inflated prices on the secondary market). This December's list runs to well over 100 models across nearly every theme, but a handful of headline sets stand out: the original 7,541-piece Millennium Falcon (75192), the 2,193-piece Nightmare Before Christmas diorama (21351), the 4,014-piece Natural History Museum (10326), and Harry Potter's Burrow Collectors' Edition (76437) are among the biggest names due to disappear. Here's the full UK breakdown, theme by theme, and what's actually worth prioritising.

What "retiring" actually means (and why it's not the same as sold out)

LEGO officially confirms retirement waves in stages throughout the year, and fan sites like Brick Fanatics track the changes as they're announced — the latest August 2026 update lists what's left standing after July's cull, with a bigger wave scheduled for the end of December. "Retiring" means LEGO has stopped manufacturing that specific set; once existing warehouse stock runs out at LEGO.com, Smyths, Argos and other UK retailers, it won't be remade. That's different from a set simply selling out mid-year and later restocking — retiring sets don't come back, and popular ones can vanish weeks or months before the official cut-off if demand outpaces the remaining stock. A handful of December-dated sets, including 21333 Vincent van Gogh - The Starry Night and 21351 The Nightmare Before Christmas, are already flagged as likely to sell out early.

The five biggest sets retiring this December

Of everything on the list, five sets carry outsized reputations among UK fans.

75192 Millennium Falcon remains the largest UCS Falcon LEGO has ever released — 7,541 pieces, £734.99, first launched in September 2017 to mark 20 years of LEGO Star Wars. It's outlasted three generations of smaller Falcon sets and is still the version most fans mean when they say "the Falcon". Once it retires, nothing else currently on sale matches its scale, and LEGO hasn't confirmed a same-size replacement for 2027.

21351 Disney Tim Burton's The Nightmare Before Christmas is the more surprising inclusion. At £169.99 for 2,193 pieces, it's one of LEGO Ideas' most successful crossover sets, combining three connectable dioramas — Spiral Hill, Jack Skellington's house and Halloween Town Hall — with eight minifigures including Jack, Sally and a two-faced Mayor. It works as both a Halloween and a Christmas display, which is exactly why Brick Fanatics flags it as one of the sets most likely to sell out before December.

10326 Natural History Museum, £259.99 for 4,014 pieces, is the newest addition to LEGO's Modular Buildings series and the first museum in the line — home to a two-storey brachiosaurus skeleton, seven minifigures and displays referencing older LEGO sets. Modular Buildings tend to hold their value well after they retire, which makes this one worth building rather than shelving unopened if you're planning to keep it long term.

Elsewhere, Harry Potter's 76437 The Burrow Collectors' Edition (£219.99, 2,405 pieces) and Marvel's 76294 X-Men: The X-Mansion (£289.99, 3,093 pieces) round out the most expensive sets on the December list — both large-scale display builds rather than play sets, and both unlikely to be reissued given LEGO's pattern of retiring Collectors' Edition and modular-scale licensed builds for good.

The rest of the December 2026 list, theme by theme

Star Wars loses the most sets by volume: alongside the Falcon, 75367 Venator-Class Republic Attack Cruiser (£559.99, 5,374 pieces), 75397 Jabba's Sail Barge (£429.99, 3,942 pieces) and 75382 TIE Interceptor (£199.99, 1,931 pieces) all go. Marvel's list runs to more than 20 sets, from the £89.99 76313 MARVEL Logo down to smaller battle packs under £15. LEGO Ideas also loses 21323 Grand Piano (£344.99, 3,662 pieces) and 21356 River Steamboat (£289.99, 4,090 pieces), both long-running favourites among adult builders. Technic's list is shorter this year but still includes 42215 Volvo EC500 Hybrid Excavator (£349.99, 2,359 pieces) and 42202 Ducati Panigale V4 S Motorcycle (£169.99, 1,603 pieces). LEGO Icons says goodbye to 10335 The Endurance (£229.99, 3,011 pieces) and 10341 NASA Artemis Space Launch System (£219.99, 4,601 pieces), while single sets close out Architecture (21060 Himeji Castle, £139.99) and Art (31216 Keith Haring Dancing Figures, £104.99). NINJAGO, DREAMZzz and the DC Batmobile pairing also lose several sets each, and every current LEGO Super Mario interactive figure starter pack is on its way out too.

Should you rush to buy, or is there a better way to decide?

31 December is a soft deadline, not a guaranteed one — smaller, popular sets and anything with a gift-with-purchase attached tend to disappear from LEGO.com weeks early, so the safest way to track live stock is LEGO's own "Retiring Soon" category rather than a fixed date. For genuinely expensive picks like the Falcon or the Natural History Museum, it's worth being honest about whether you'll actually build and display it before spending £250-plus. That's really the only advantage of renting instead of buying outright — it lets you spend a month with a set on your own shelf before deciding whether it earns a permanent spot. LendABrick's plans start from £9.49 a month, undercutting every other UK LEGO rental service, and it's currently the only one offering a VIP tier for access to premium sets worth up to £1,500 — worth a look if you'd rather test a build than commit to full retail price on something that might retire before you've even opened the box.
