Best Lego deals October 2025

We've picked out sets with significant or new discounts from Lego's most popular ranges.

We looked at the price history of each set, total discounts and cost per brick to bring you deals that we genuinely believe to be good value.

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.

Great bargains on Lego Advent Calendars

Our pick: Lego Star Wars Advent Calendar (2025) 75418

*Average price in the last six months: £29.83. Cheapest price in past six months: £24.98

Number of bricks: 263

Watch out for: Series of smaller builds

Each day in the lead up to Christmas, this set has small builds that make up a Christmas-y droid workshop once completed.

It's not a huge discount with only a fiver off, but it's still a bit cheaper than buying direct from Lego.

Number of bricks: 1,363

Watch out for: Lots of tiny pieces

Modeled after a zen garden, this set features small builds of cherry blossom trees, a small bridge, and a pavilion.

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: £550.99

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.

While we saw it go for its cheapest-ever over Amazon Prime day, there are still some good bargains on it.

 Best 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.

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.

Each car has its own unique serial number, which is linked to exclusive online content.

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

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.
