Loved by people of all ages, LEGO® bricks are one of the most popular toys in the world. But there comes a time when many LEGO® collections are no longer being used. Perhaps your children have outgrown their LEGO® toys, you're having a clear-out or you've uncovered a box of loose LEGO® bricks in the loft that you want to get rid of sustainably. Whichever it is, selling to us is a great way to free up some space, earn some extra cash and give your unwanted bricks a new home
Selling by weight is the best choice if your LEGO® sets and bricks have become mixed together over the years and you don't know which LEGO® set each brick came from. Rather than trying to identify every LEGO® set, you can receive an instant offer for the whole collection as it is.

If your LEGO® collection includes complete or partially complete LEGO® sets, you can sell those too! Complete LEGO® sets are often worth more than loose LEGO® bricks, which is why we recommend adding them separately. We'll give you an individual offer for each LEGO® set, while your loose LEGO® bricks can still be sold by weight.
If you do also have complete LEGO® sets, there's no need to place a separate order. Simply add your LEGO® sets and loose LEGO® bricks to the same basket, accept your offers and send everything together in one parcel.
WeBuyBricks is the best place to sell both LEGO® sets and loose bricks. If your LEGO® collection is mixed together, selling by weight is often the quickest and easiest option. WeBuyBricks lets you sell loose LEGO® bricks online by the kilo, providing an instant price, free postage and fast payment, without needing to create listings, deal with bids or meet buyers in person.
The value of your loose LEGO® bricks depends on the size and contents of your collection. When selling by weight, we’ll calculate your offer based on the information you provide, such as the weight in kilos and what theme you think is most present. If your collection also includes complete LEGO® sets, adding them separately could increase the total offer you receive.

Yes. You can add complete LEGO® sets and loose LEGO® bricks to the same basket. We'll provide separate offers for each LEGO® set and a weight-based offer for your loose LEGO® bricks, so you can send everything together in one sale.
Your LEGO® sale should be packed securely to help prevent damage or loss during transit. We recommend placing your LEGO® bricks in strong bags before boxing them up. Take a look at our full packaging guidelines for more information.

We're passionate about giving unwanted LEGO® bricks a second life. Every LEGO® collection we receive is carefully checked, with genuine LEGO® bricks and LEGO® sets prepared for resale wherever possible, so they can be enjoyed by another builder for years to come.
By selling your unwanted LEGO® collection instead of throwing it away, you're helping to keep genuine LEGO® bricks in circulation for longer and reducing unnecessary waste. It's a simple way to clear some space at home, earn some extra cash and make sure your LEGO® bricks continue to be loved rather than left unused.
If any genuine LEGO® bricks or pieces aren't suitable for resale, we'll always look to handle them as responsibly as possible.
We don't expect your LEGO® collection to be perfectly organised, but it does need to be made up of genuine LEGO® bricks and pieces and be in good condition. A few signs of normal play are absolutely fine, but your LEGO® bricks should be clean, genuine and ready for a new home.
To help us process your order quickly and avoid any delays, please make sure your sale only contains genuine LEGO® products. Unfortunately, we can't accept other building brick brands or household items mixed in.
