Best HP Desktops Under £300

HP desktops have long been a staple of the UK home computing market, and the sub-£300 bracket has become considerably more competitive over the past twelve months. Refurbished and renewed listings now sit alongside brand-new compact machines, meaning buyers can access genuine quad-core and even hexa-core processors without stretching the budget. This guide is aimed at home users, students, remote workers, and anyone replacing an ageing tower who needs reliable everyday performance for web browsing, word processing, video streaming, light photo editing, and video calls. Since last year, the main shift has been the wider availability of 12th-generation Intel Core processors and Windows 11 Pro machines in the refurbished channel at prices that were previously impossible at this price point. SSD-only configurations have also become the norm, eliminating the sluggishness that plagued older budget desktops. Whether you want a tiny form-factor machine or a more traditional small tower, there is a credible HP option here for you.

Quick Verdict

Best Overall: HP EliteDesk 800 G6 Mini (refurbished) delivers 10th-gen Core i5 power, an NVMe SSD, and a whisper-quiet chassis that fits anywhere on a desk. Best Value: HP ProDesk 400 G6 SFF gives you a full-size tower with expansion room and solid i5 performance for the keenest price in the lineup, making it the pick for anyone who wants to add RAM or a graphics card later.

Spec Comparison Table

How We Picked

Every machine in this roundup was assessed against a consistent set of criteria relevant to UK home users shopping under a £300 budget. We considered processor generation and core count, as these have the greatest impact on everyday responsiveness. RAM and storage configurations were evaluated both as shipped and with regard to upgrade potential, since many buyers will want to expand capacity over time. Form factor was assessed for real-world desk suitability, including port selection, noise levels, and physical footprint. Build quality and refurbishment grade were considered, with a preference for machines sourced from reputable sellers with a minimum 90-day warranty. Windows 11 compatibility was weighted heavily given the approaching end of Windows 10 support. Finally, value for money was assessed relative to competing brands at the same price point, including Acer, Lenovo, and Dell refurbished alternatives.

Buying Guide

Processor: How Much Power Do You Actually Need?

For basic home use, which covers web browsing, streaming, email, and word processing, a quad-core Intel Core i3 or i5 from the 8th generation onwards is sufficient. If you regularly run multiple applications at once, work with large spreadsheets, edit photos, or attend multiple video calls, a six-core i5 from the 9th or 10th generation is a meaningful step up. Avoid Celeron and Pentium processors if your budget allows, as they lack hyperthreading and feel sluggish under any multitasking load. AMD Ryzen 5 Pro processors, as found in the EliteDesk 705 G4, offer a good alternative with stronger integrated graphics.

RAM: 8 GB or 16 GB?

Windows 11 runs acceptably on 8 GB of RAM for light use, but if you keep many browser tabs open, use Microsoft Teams or Zoom regularly, or run any creative software, 16 GB makes a noticeable difference. Most refurbished machines in this price range ship with 8 GB, but RAM is inexpensive to upgrade, and the commercial HP machines in this list all use standard DDR4 SO-DIMMs or DIMMs that are easy to source. Check the maximum supported RAM for your chosen model before buying, as some older platforms cap out at 16 GB.

Storage: SSD Is Non-Negotiable

Any desktop you buy today should have an SSD as the primary drive. A machine with a traditional spinning hard drive as the boot drive will feel frustratingly slow by modern standards, regardless of processor speed. NVMe SSDs are faster than SATA SSDs, but both are dramatically quicker than a hard drive for everyday use. 256 GB is the minimum practical size for a Windows 11 installation with a reasonable amount of software and files; 512 GB is preferable if you store photos, music, or video locally.

New vs. Refurbished

At the sub-£300 price point, refurbished commercial HP desktops consistently offer better specifications than brand-new consumer machines. A refurbished HP EliteDesk with a six-core i5 and 16 GB of RAM will outperform a new Slimline with a Core i3 in every measurable way. Reputable refurbishers on Amazon Renewed and similar platforms offer 90-day to one-year warranties, and Grade A refurbished units typically show minimal cosmetic wear. The key is to buy from sellers with strong feedback ratings and clear grading descriptions.

Is HP Better Than Acer for Desktops?

HP and Acer both produce reliable desktop computers, but they serve slightly different markets at this price point. HP's commercial EliteDesk and ProDesk range, available refurbished, offers enterprise-grade build quality, better component longevity, and more generous port selections than Acer's consumer Aspire and Veriton lines. Acer's consumer desktops tend to have more attractive chassis designs and are more widely available new, but the internal components are typically less robust. For home users who prioritise long-term reliability and performance per pound, refurbished HP commercial machines are generally the stronger choice. For buyers who want a new machine with a retail warranty and are not comfortable with refurbished hardware, Acer's Veriton range is a credible alternative.

What About Wi-Fi?

Most HP commercial desktops do not include built-in Wi-Fi as standard, as they were designed for office environments with wired Ethernet. If you need wireless connectivity, check the specific listing carefully before purchasing. Some refurbished units have had Wi-Fi cards added, and HP offered optional Wi-Fi modules on several models. A USB Wi-Fi adapter is an inexpensive workaround if your chosen machine lacks built-in wireless, but a wired Ethernet connection will always be faster and more stable for home use if your router is accessible.

Final Verdict

The HP EliteDesk 800 G6 Mini is the overall winner for most home users under £300. It combines a genuinely capable six-core 10th-generation processor with a near-silent, compact chassis, excellent port selection, and enterprise build quality that will serve reliably for years. The NVMe SSD and typical 16 GB RAM configuration mean it arrives ready to use without immediate upgrades. For buyers who want expandability and the option to add a discrete GPU later, the HP ProDesk 400 G6 SFF is the best value alternative, offering the same generation processor in a chassis that accepts low-profile graphics cards and additional storage. Both machines represent significantly better value than brand-new consumer desktops at this price, and either will comfortably handle the demands of a modern UK home.
