Every house has one: the tub. The big plastic box of LEGO that migrated from the playroom to under the bed to the loft, and hasn't been opened since. The kids have grown up, you've reclaimed every other corner of the house, but that tub just sits there.
Here's the nice surprise — it's not clutter, it's cash you haven't collected yet.
Why LEGO is worth decluttering for money (not just binning)
Most things you declutter you give away or throw out. LEGO is different — it holds its value remarkably well, even years later, even all mixed up. The bricks get a second life with other families and builders, which is why buyers will pay for the lot rather than you paying to skip it.
So before that tub goes to the charity shop or the tip, it's worth knowing it could put real money back in your pocket instead.
Where the LEGO is hiding
Before you sell, do one quick sweep — LEGO has a habit of scattering. Common hiding spots:
- The obvious tub or toy box
- Down the back of the sofa and under beds (loose bricks and minifigures)
- Old shoeboxes and ice-cream tubs in the loft
- That one drawer of "bits" in the kitchen
- Inside other toys' boxes
Gather it all into one place. Minifigures especially are worth hunting down, as the little figures often carry more value than the bricks.
You really don't need to sort it
The single biggest thing that stops people decluttering LEGO is the dread of sorting it. Skip that entirely. You don't need to:
- Separate it into sets
- Sort by colour or size
- Find the boxes or instructions
- Rebuild anything
A big mixed tub is exactly what buyers expect. Loose bricks are valued by weight, so the whole jumble goes together as-is.
From tub to cash in four steps
- Weigh it roughly and get a price. A bathroom-scale guess is fine for loose bricks; list any complete or sealed sets separately if you spot them. See what your tub is worth →
- Bag and box it. Pop loose bits in bags so they don't escape, then into a sturdy box.
- Send it free with a prepaid label or home collection.
- Get paid, usually the next day.
The best bit: the space back
Decluttering is really about the after, not the before — the empty shelf, the loft you can actually walk into, the drawer that closes. Turning the LEGO into a bit of cash on the way out just makes it that much more satisfying.
