15 Best Prime Day Lego deals to grab, including Star Wars, Lord of the Rings and more

This is my favourite Lego set of all time, and the best one I've ever built. It's full of gorgeous little details, but is also simply massive, and will give you hours upon hours of satisfying building – best done while watching the movies, in my opinion.

If Rivendell is my favourite set, this is the one I want the most badly – a towering kit that has thousands of pieces and stands a couple of feet tall, but is so intricate and impressive once built. It's a monster in terms of size, but this discount makes it more palatable in terms of price.

For those wanting to indulge their love of The Lord of the Rings without having to take out a second mortgage, this is the most affordable and approachable kit in the range, and it's also the easiest to display. It shows off one of cinema's most iconic scenes, in some style.

For a more recent cinematic tie-in, look to Project Hail Mary, which got this charming version of the in-movie spaceship, along with the film's two protagonists. It's a fun little kit that doesn't cost the earth and is a great buy if you loved the film.

It's not Prime Day without some Lego Star Wars deals, and this huge discount cuts the price of one of the most expensive Lego sets ever. This massive cross-section of the Death Star is a beast, full of dioramas and rooms, and getting it for this price is a rare option.

The biggest single discount in this whole list goes to this true modern classic of a set. It lets you build the Millennium Falcon in unbelievably detail and at true minifig scale, with thousands of pieces. It's iconic for a reason, and getting nearly £190 off can't be sniffed at.

If you want a Lego Star Wars set but don't have a huge budget, this might be your best pick – rather than one of the sets aimed at kids, this TIE Interceptor is from the high-end Ultimate Collector Series, and has the detail to match that billing.

For those who believe in sci-fi being a broad church, this is the first truly great Star Trek set from Lego. I built it at the start of 2026 and loved every minute – it's a classic ship and a really fun, involved build. It's also cheaper than many similar-sized Star Wars kits, for what it's worth.

If you prefer your space escapades to be a little bit more grounded in reality, this is the perfect set for you. It's NASA-backed, and lets you build the truly iconic Artemis launch system, complete with its launch tower and boosters.

To cap off this list of space-themed kits, my last pick in the area is a Technic kit, and a brilliant one for aspiring astronomers. This slice of the solar system is a superb way for kids learning about space to get a grip on how orbits work, and is a really fun and rewarding build.

Sticking with Technic for another kit, there's no motorbike brand quite like Ducati, for me. This brilliant kit lets you build one of its sleekest ever bikes, the Panigale V4 S, and features suspension and intricate motor details. It's a superb display piece and great for motorheads.

If you're looking for aesthetically pleasing Lego sets, this is a doozy, especially if you're a lover of classical music or a piano player yourself. Full of lovely intricacies and comprised of more pieces than you might think, it's a great pick if you have a more eclectic style in your home.

For tech-lovers like us there's no denying the power of this kit, which immortalises one of the most memorable and beloved cameras ever. It's a build that's more impressive than its price tag implies, and a great gift for parents who might have actually had the original camera back in the day.

For world travellers, or those who love Rome, this is a beautiful option. In fact, given how hard it can be to get a good view of the Trevi fountain in person, this might just be a better way to experience it – for much less than the cost of a trip.

Our final set is a lovely little one that focuses more on aesthetics than on recreating a genuine scene. It's a beautiful woodland cottage with a garden, full of oranges and greens, and is a beautiful piece to get out once summer starts to wind down.
