How to Choose a LEGO Set in the UK - Buying Guide

There is a huge variety of LEGO sets available to buy online in the UK, that vary in size - from individual mini-figures to colossal sets with many thousands of pieces - difficulty, and theme. When choosing a LEGO set to buy for you, your child, or someone else, you need to consider a range of factors, including age, theme, and skill level. 

Consider Your Target Age Range

LEGO products are helpfully labelled with the target age range for each product - from DUPLO, aimed at under-fives to complex sets for older kids and grown-ups. LEGO prides itself on the wide age range of those who love its products and many of the boxes are labelled as being targeted at builders between four and 99!

DUPLO Is the Perfect Choice for Builders up to Five

DUPLO is a range aimed at children under six, and comprises of a range of larger bricks and figures to suit little hands that have not yet gained the dexterity to handle the tiny “big kid” LEGO bricks. However, many older children - and adults! - have also been caught enjoying DUPLO.

Available, like standard LEGO, in a variety of themed sets as well as creative brick sets, DUPLO is compatible with the smaller LEGO bricks so you can build creations incorporating both types of blocks, which can work really well as your little builders grow.

Standard LEGO Best Suits Builders Over Six

Standard LEGO bricks are generally best suited to those over six years of age, but the complexity of individual sets can affect which age group becomes a better fit for them. If in doubt, look at the packaging for the set as LEGO handily labels each set according to their target age range.

The larger sets with more pieces are generally more suited to older children or even adults, and additional features in ranges, such as LEGO Technic, also adds to their difficulty level, making them better for older children or adults.

Choose a LEGO Range to Suit Their Interests

Finding the right theme for a LEGO set means knowing a little about the interests of the builder you’re buying for. LEGO has partnered with other brands to bring you characters from film series such as Harry Potter, while also developing some of their own fun characters.

LEGO City Recreates the Real World in Bricks

LEGO City is a range developed to reflect the real world and includes a wide range of sets that feature vehicles, buildings and more city-themes. Each set can stand alone or be collected to form part of a modular cityscape. There are tiny sets that have one or two mini-figures as well as a small vehicle or building, and there are huge sets that include multiple complex vehicles and buildings.

These sets reflect things found in life and LEGO City is a really popular range that, once built, also serves as fun toys to play with.

Little Ninjas Will Love LEGO Ninjago

The LEGO Ninjago range is aimed at children over six and focuses on a group of ninja heroes. The sets vary in complexity, with a few for ages 6+, but most being generally aimed at the 8-14 years age range. These sets tie in with LEGO’s Ninjago film and tv series.

Ninjago sets are a good choice for anyone with an interest in martial arts or fighting baddies. They are popular with girls, boys and grown-ups alike!

LEGO Sets With TV and Film Themes Are Great for Fans Over Seven

In a somewhat magical partnership, LEGO has produced a series of enchanting Harry Potter minifigures and sets that are sure to be the perfect choice for any Harry Potter fan.

These sets are generally of medium complexity, although, there is a Hogwarts Castle set for older builders 16+ that boasts over 6,000 pieces! If you’ve got a Harry Potter fan to buy for, you might want to consider one of the great sets available featuring Harry and gang!

If, however, your child is more into superheroes and the Marvel Cinematic Universe, there are lots of LEGO sets with this theme too! 

Find LEGO Friends for Some Girl Power

This fun range revolves around a group of friends who live in Heartlake City. With figures that are a bit bigger than the usual LEGO minifigure, these characters are more lifelike. The sets can stand alone, although many can also be combined to build a complex Heartlake City set. 

You can choose between a range of sets from a pet parlour to a glamping site as well as lighthouse rescue set. LEGO Friends is aimed at builders over six years of age and targeted primarily at girls. There is also a TV series of the same name, featuring the LEGO characters.

LEGO Sets Vary in Size and Complexity

In addition to the vast array of themes available, LEGO sets vary greatly in size and complexity, from individual minifigures to huge, complex sets for adults and older teens. In choosing the size of the set you wish to purchase, consider the recipient’s level of skill with putting together pieces of varying size, as well as their willingness to follow complex instructions. 

LEGO Technic Offers a New Dimension

This series from LEGO was developed to give experienced LEGO builders additional challenges in their builds. Using additional real-life features such as gearboxes, motors and steering systems, these sets offer a new dimension in LEGO building.

Most of these sets are aimed at the over nines, although a few, simpler Technic sets are available for children from seven. Technic sets are perfect for young builders who are keen to extend their skills and try new things.

LEGO Creator Expert Offer the Ultimate Building Challenge

Creator Expert is the advanced series' developed to offer the ultimate building challenge for expert builders. The series includes modular houses, cars, world buildings, and more. This range is best for older teens or adults who are very keen LEGO model builders.
