* References to ‘Average price' and 'Cheapest price' are based on Which? market knowledge and information supplied by our partners. Average price is checked for the six calendar months prior to publication. Not all retailers are included in our checks.

Our top bargain: Technic Planet Earth and Moon in Orbit 42179

*Average price in the last six months: £61.67. Cheapest price in past six months: £42.90

Number of bricks: 526

Watch out for: Not motorised

This space set features a model of the earth and moon orbiting around the sun. With the turn of a crank, it'll show how our home planet and moon spin circles around the sun which sits in the centre of the model.

You can even see the phases of the moon on a small dial just under where the moon rotates. Just be sure you place the stickers of the moon phases on in the correct places.

Great bargains on Lego Advent Calendars

Our pick: Lego Harry Potter Advent Calendar (2025) 76456

*Average price in the last six months: £29.58. Cheapest price in past six months: £19.97

Number of bricks: 278

Watch out for: Series of smaller builds

Each day in the lead up to Christmas, this set has small builds that include Christmas-y Hogwarts students, as well as small builds of critters and pets from the wizarding world.

Over the last few weeks we've been seeing the price drop on this set.

 Best Black Friday deals on Lego Icons and Adult sets

Our pick: Botanicals Japanese Red Maple Bonsai Tree 10348

*Average price in the last six months: £54.37. Cheapest price in past six months: £37.99

Number of bricks: 474

Watch out for: Not as many pieces as the popular bonsai tree 10281 set

Many of Lego's botanicals line of sets is focused on mindfulness through building small plants. These tend to look great on shelves, and won't require nearly as much maintenance as a real plant would.

This one features a small bonsai tree that has red and orange leaves. It also comes in a small buildable pot.

Runner-up: Lord of the Rings: Rivendell 10316

*Average price in the last six months: £421.69. Cheapest price in past six months: £365

Number of bricks: 6,167

Watch out for: The number of bricks and our atrocious puns

It's the return of the king(-sized bargain)! This set features the scene in the first film where the fellowship of the ring is assembled. You'll get several minifigures; including Frodo and Bilbo Baggins, Gandalf, a Lego-las, Aragorn, and much more.

Just keep in mind that it's a massive build at more than 6,000 pieces, so we'd recommend you set the mood and put it together it while watching the extended edition LOTR films.

 Top deals on Star Wars Lego

Our pick: Millennium Falcon UCS 75192

*Average price in the last six months: £700.44 Cheapest price in past six months: £524.99

We spotted it cheapest from Smyths Toys (£539.99 — click and collect only), otherwise you can compare prices below:

Number of bricks: 7,541

Watch out for: Still costs as much as a Best Buy fridge

This massive set is the size of a small coffee table once built, but it's one of the most detailed sets of the iconic starship. It also has a fully furnished interior.

It's currently not the cheapest we've ever seen it go for, but it's still a great bargain on one of Lego's biggest sets.

 Best Black Friday deals on Harry Potter Lego

Our pick: Harry Potter Hogwarts Castle

*Average price in the last six months: £387.48. Cheapest price in past six months: £285.99

Number of bricks: 6,020

Watch out for: A lot of pieces

This set features the iconic Hogwarts castle, but just know that it's not to minifigure scale. Instead, it is scaled for 'microfigures' which are around the size of a 1x1 block.

Not only do you build the castle itself, this set also includes Hagrid's Hut, the Whomping Willow and five boats. It's not its cheapest ever price, but we still think it's a bargain.

 Best Black Friday bargains on Disney Lego

Our pick: Lilo and Stitch Beach House 43268

*Average price in the last six months: £78.87. Cheapest price in past six months: £54.99

Number of bricks: 834

Watch out for: Back of build is exposed

This Hawaiian beach house is the home of Lilo and her mum, Nani, and has six furnished rooms packed with references to the film. You'll get minifigures of Lilo and Stitch (of course), plus Nani, David, and Mr. Bubbles.

It's the cheapest we've seen it go for this month, making it the best Disney Lego deal.

 Great deals on Lego Technic sets

Our pick: Porsche GT4 e-Performance 42176

*Average price in the last six months: £144.65. Cheapest price in past six months: £109.99

Number of bricks: 836

Watch out for: Remote controlled, but only through an accompanying app

This set recreates Porsche's all-electric race car using Technic pieces. It can also double as a remote-controlled car, but you'll need to download an app onto your phone in order to drive it around.

It features working headlights, and the motors used are rechargeable via USB-C.

 Great deals on Marvel Lego

Our pick: Marvel Logo 76313

*Average price in the last six months: £80.36. Cheapest price in past six months: £58.89

Number of bricks: 931

Watch out for: Missing one notable Avenger

This set is a build of Marvel's logo, the company that published stories about superheroes like Iron Man, Captain America, the Hulk, and many more.

You'll get minifigures of five of the 'classic' Avengers (sorry Hawkeye fans, he's not included) that can pop out of the logo with the push of a few buttons.

Best bargains on Lego Friends

Our pick: Family Holiday Beach Resort 42673

*Average price in the last six months: £107.74. Cheapest price in past six months: £69.99

Number of bricks: 1,140

Watch out for: Not fully enclosed

This set comes with heaps of beachside play features. It comes complete with a water slide, metal detecting, an ice cream stand, and plenty of surfboards.

You'll get six mini dolls, plus a baby turtle and a dolphin.

When is Lego discounted?

It's likely that throughout the year many retailers will have their own deals going on. Plus, Lego itself may have some deals themselves — especially on sets that are going to be discontinued soon. You can check Lego's deal page, and check which sets are being retired soon from their website.

How can I save money on Lego sets?

While we can't put a firm number on how much a set is typically discounted, there are usually several on sale throughout the year, so we'll keep an eye out and update this page with the best deals we find.

You'll typically find most deals from third-party retailers instead of Lego themselves. While you'll usually get some extra goodies thrown in when you buy direct, it may not be worth the the extra savings.

Where can I buy discounted Lego sets?

At the moment, most Lego deals can be found on Amazon, Argos, Smyth's Toys and Very. They'll often sell Lego sets cheaper than on Lego's own website.

You can check the stock of what each retailer has on sale below and see their full offerings: 

• Amazon
• Argos
• John Lewis
• Smyth's Toys
• Very
• Lego

If you're looking for more sets, you can take a peek at Lego's sales and deals page.

As a general rule of thumb, paying 10p per brick/part is a pretty typical price for Lego. Branded and franchised Lego sets like Star Wars, Disney, Mario, Marvel, and Harry Potter tend to be a bit more expensive – at around 11 to 12p per brick.

Lego's own-branded set lines that don't use as many set-specific parts like Icons, Ideas, Classic, Modular buildings, and Creator – will tend to cost around 7 to 8p per brick.

Should I buy direct from Lego?

You can find some discounts direct from Lego, but it's still one of the more expensive options. You can see which sets have been discounted on Lego's website.

Lego isn't cheap – to make or to buy. While you can generally get sets cheaper by buying from other retailers, there are still perks to picking up your pieces from Lego itself.

Sometimes when you order directly from the Lego store (either online or in person), you'll get a small bonus set when you spend past a certain threshold or buy a certain set. The bonus gift tends to change each month, and sometimes you can even get multiple gifts. Keep track of the bonus free sets on Lego's website.

You can also sign up to Lego's Insider programme where you earn points to get money off future sets and access to exclusive sets and deals.
