What are the best laptops under £400 to buy in the UK?
Our top pick for Laptops Under £400 in the UK is the Acer Aspire Go 15 AG15-32P Laptop (Intel N150, 8GB, 128GB).
The Acer Aspire Go 15 AG15-32P Laptop suits a buyer who wants a 15.6" Full HD screen with 8GB of RAM and a stated battery life of up to 8 hours; confirm the operating system on the Amazon page, because the listing text does not name it.

The Acer Aspire Go 15 AG15-32P is our top pick among laptops under £400 because its listing states an Intel N150 processor, 8GB of RAM, 128GB of storage, a 15.6" Full HD (1920x1080) display, a battery life of up to 8 hours from a single charge, dual-band Wi-Fi 6 and a 1 year manufacturer warranty; it does not name the operating system or the storage type. For Windows 11 and an SSD named on the listing, the ASUS Vivobook 15 E1504FA states Windows 11, 8GB RAM and a 128GB PCIe SSD, though its listing says no power adaptor is supplied. For a Windows edition and a port list in writing, the Lenovo IdeaPad Slim 3 Gen 8 states Windows 11 Home, with 4 GB of RAM and 128 GB of UFS 3.1 storage.
This guide compares five laptops from Acer, ASUS, LEEDOW and Lenovo, using what each listing states: processor, RAM, storage, screen, operating system, battery and warranty. Stated RAM runs from 4 GB to 8GB and stated storage from 128GB to 256GB. Two listings name Windows 11; the other three do not name an operating system.
Buying guide
What should you look for in Laptops Under £400?
1Operating system: the Lenovo IdeaPad Slim 3 Gen 8 states Windows 11 Home with an Office trial, and the ASUS Vivobook 15 states Windows 11 without an edition. The two Acer Aspire Go listings and the LEEDOW listing do not name an operating system, so confirm it on the Amazon page before buying.
2Processor and RAM: the Lenovo lists an Intel N100 with 4 GB of RAM; both Acer Aspire Go laptops list an Intel N150 with 8GB; the ASUS lists an AMD Ryzen 3 30, as written on the listing, with 8GB; the LEEDOW lists a Core i7 processor with 8GB but gives no model number.
3Storage: check the type as well as the size. The Lenovo states 128 GB of UFS 3.1 storage, the ASUS a 128GB PCIe SSD and the LEEDOW a 256GB SSD. Both Acer listings say 128GB of storage without naming the type.
4Screen: the Lenovo and the LEEDOW are 14 inch with 1920 × 1080 stated. The Acer AG14-32P's bullets state 14" WUXGA (1920x1200), although its title says Aspire Go 15. The Acer AG15-32P states 15.6" Full HD (1920x1080), and the ASUS states 15.6" Full HD without a pixel figure.
5Battery and charging: both Acer listings state up to 8 hours from a single charge. The Lenovo states a 47Wh battery and up to 2 hours of use from 15 minutes of charging, and the LEEDOW a 51.9Wh battery; neither gives a total battery life in hours. The ASUS states no battery figure and says a power adaptor is not supplied.
Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
These five listings disclose different things. The Lenovo names its Windows edition, storage type, ports and battery capacity; the two Acer listings give battery life, webcam and Wi-Fi detail but no operating system or storage type; the ASUS names Windows 11 and a PCIe SSD but no port list or battery figure; the LEEDOW lists 9 ports and a battery capacity but no processor model or operating system. All five state a 1 year warranty.
Our Take
As a default, the Acer Aspire Go 15 AG15-32P: Intel N150, 8GB of RAM, a 15.6" Full HD (1920x1080) display and a stated battery life of up to 8 hours, with the caveat that its listing names no operating system. For Windows 11 named on the listing and a 128GB PCIe SSD, the ASUS Vivobook 15, whose listing says no power adaptor is supplied. For the largest stated storage, the LEEDOW with its 256GB SSD; for a stated Windows edition and port list, the Lenovo IdeaPad Slim 3 Gen 8, which states 4 GB of RAM.
Questions & answers
Frequently asked questions
Which laptops under £400 come with Windows 11?
Two listings on this page name it. The Lenovo IdeaPad Slim 3 Gen 8 states Windows 11 Home with an Office trial, and the ASUS Vivobook 15 E1504FA states Windows 11 without naming the edition. The two Acer Aspire Go listings and the LEEDOW listing do not name an operating system, so confirm it on the Amazon page before buying.

Two listings say so: the ASUS Vivobook 15 states a 128GB PCIe SSD and the LEEDOW a 256GB SSD. The Lenovo states 128 GB of UFS 3.1 storage. Both Acer Aspire Go listings state 128GB of storage without naming the type.
