Best Raspberry Pi Alternatives 2026 (UK Availability)

Looking for Raspberry Pi alternatives in the UK that you can actually buy today? Pi 5 supply has improved, but it is no longer the obvious default - and several rival single-board computers now beat it on performance per pound. This guide cuts through the spec sheets and shows which board (or which mini-PC) makes sense for a home server, Pi-hole, media box, NAS or Home Assistant rig in 2026.

We have grouped the boards by what they are actually good for, with current UK retailer pricing and the gotchas that the marketing pages never mention. Where a £100 N100 mini-PC blows them all out of the water, we say so.

The Raspberry Pi Foundation reset expectations with the Pi 5 in late 2023 - finally a meaningful jump from the Pi 4 in CPU, IO and graphics. Three years on, two things have changed.

First, supply is no longer pathological. The Pi Hut, Pimoroni and Mouser UK all carry 8GB Pi 5 boards at £75-£85 most weeks, occasionally £69 on offer. Second, and more interestingly, several Chinese single-board computer makers have built on the same Rockchip RK3588 SoC and shipped boards that comfortably outperform the Pi 5 on multi-core CPU, GPU and NPU benchmarks at similar price points.

That said, the Pi 5 still wins on three things you should not underestimate: the software ecosystem (every smart-home tutorial assumes a Pi), the active cooling case with the official 27W power supply, and the HAT compatibility for anyone using GPIO headers for relays, sensors or screens. If those matter to your project, a Pi 5 is the right answer and you should stop reading.

If you are mostly running headless Docker containers, want more RAM, or care about NPU performance for local AI, the alternatives below are worth a look.

Orange Pi, the Chinese single-board computer family popular as a Raspberry Pi alternative, 5 Plus uses the same Rockchip RK3588 SoC as several other premium boards - 8 cores (4×A76 + 4×A55), Mali-G610 MP4 GPU, and a 6 TOPS NPU. UK availability is steady through AliExpress official store and a handful of UK-based resellers; expect to pay around £130-£160 for the 16GB version, considerably more than a Pi 5 but you get double the RAM and significantly faster CPU.

What makes it stand out versus the Radxa Rock, the Radxa-branded single-board computer series with higher RAM options, 5B (same SoC) is the layout: dual 2.5GbE Ethernet, an M.2 NVMe slot on the underside, HDMI input as well as output, and a more sensible power-delivery setup. If you are building a small home NAS or a router running OpenWrt, the dual 2.5GbE alone justifies the price gap over a Pi 5.

Radxa Rock 5B shares the RK3588 with the Orange Pi 5 Plus but takes a different approach: full-size HDMI 2.1 (up to 8K output), Pi-style 40-pin GPIO header, PoE support via an add-on, and significantly better community documentation than any other RK3588 board. UK retailers include Mouser UK (around £150 for 16GB) and Distrelec; the Radxa shop ships from China with 3-5 day delivery via DHL.

The Radxa community wiki is the best Linux-on-RK3588 resource on the open web, including detailed kernel configuration, mainline kernel support timelines, and a steady stream of Debian and Ubuntu rebuilds. If you are the kind of person who wants to flash a custom OS and tweak device-tree overlays, this is the board to buy.

Released in late 2025, the Radxa Rock 5 ITX is the first ARM single-board computer in a true mini-ITX form factor, designed to drop into a standard mini-ITX case alongside a real desktop PSU and 2.5" or 3.5" drives. It uses the same Rockchip RK3588 as the Orange Pi 5 Plus and the Rock 5B, but with the connectivity you would expect on a desktop board: four SATA III ports, dual 2.5 GbE, an M.2 NVMe slot, and a 24-pin ATX power connector.

UK pricing starts around £200 for the 16 GB RAM variant, climbing to £250 for 32 GB. That puts it well above any other board on this list and squarely in the same money as an N100 mini-PC with similar memory. The pitch is power efficiency and ARM-native software (Home Assistant OS, the official operating system that runs Home Assistant on dedicated hardware,, Frigate NVR, container workloads), not raw value.

Where this board genuinely makes sense: a low-power home server combining NAS duties with Plex and Home Assistant in a single appliance, with multiple internal drives and no compromises on connectivity. Where it does not: as a learning board or a project starting point, where the £200+ entry cost and complete-system expectations make it overkill versus a Pi 5 or a Rock 5B.

Software support is the usual RK3588 story: Armbian and Ubuntu work well; the Radxa-supplied Debian image is slightly behind on kernel; Home Assistant OS does not yet ship an official image for the Rock 5 ITX specifically, though Home Assistant Container on Armbian is a viable substitute.

Banana Pi BPI-F3 is the most interesting board on this list if you care about computing futures rather than raw speed. It uses the SpacemiT K1, an 8-core RISC-V SoC at 1.6 GHz. RISC-V is an open instruction set architecture (ISA) that has been gaining serious commercial traction - Western Digital, Seagate, and increasingly Nvidia are using RISC-V cores in their embedded silicon, and Ubuntu has shipped a RISC-V port for several releases.

Practically, the BPI-F3 is not as fast as the RK3588 boards. Multi-core CPU performance is roughly Pi 4 territory. What you get instead is direct exposure to the architecture that is most likely to power post-Arm hobbyist boards by the end of the decade. It is the board to buy if you want to write or port software for RISC-V Linux, not the board to buy if you want to run Plex.

Khadas VIM4 uses the Amlogic A311D2 - an 8-core SoC paired with a Mali-G52 MP8 GPU. It is the standout choice for anyone building a media-centric machine because of its hardware video decoders: H.265, AV1 and VP9 all decode at 4K60 with sub-watt power draw. Khadas sells direct to the UK with Royal Mail tracked delivery; expect to pay £140-£160 with the official cooling kit.

The VIM4 is also genuinely good at being a small Linux desktop. The official Ubuntu 22.04 image runs well, the optional active-cooling fan is whisper-quiet, and HDMI-in lets you use it as a capture device or KVM target - neat tricks not many sub-£200 boards offer.

Here is the inconvenient truth: a Beelink, GMKtec or Trigkey Intel N100 mini-PC at £140-£180 obliterates every single-board computer in this guide at general-purpose Linux server tasks. The N100 is a 4-core Alder Lake-N processor that benchmarks at around 5,500 in Passmark single-thread - roughly 3× a Pi 5 and 1.5-2× the fastest RK3588 boards. It supports up to 16GB DDR5 RAM, has a real NVMe slot for £40 of fast storage, two USB-C ports, and idles at around 6W.

What you give up: the GPIO header, the ARM-specific software ecosystem, and the tinker-friendly form factor. For Home Assistant, Plex/Jellyfin, Pi-hole, AdGuard, Nextcloud, Docker workloads and almost any combination of those, an N100 box is the smarter buy. The exceptions are projects that genuinely use GPIO (relays, sensors, displays), where ARM single-board computers remain the right tool.

UK retailers worth checking: Amazon UK (Beelink and Trigkey both have a presence), Box.co.uk, and Scan Computers. Refurbished N100 mini-PCs occasionally appear on eBay UK at £100-£120, which is the best value in this entire category.

UK availability is genuinely one of the harder parts of buying outside the Pi ecosystem. Here is where to look for each board.

Skip the spec wars. Here is the practical answer for the projects most readers are actually building.

Home Assistant OS (HAOS) - the all-in-one image that drives most Home Assistant installs - ships official builds for the Raspberry Pi family, Odroid N2+ and a few generic x86 targets. Everything else on this list runs Home Assistant Supervised (or Container) on top of a Debian or Ubuntu base, which gets you 95% of the functionality but you maintain the OS yourself.

In practical terms: Pi 5 and N100 mini-PCs are first-class citizens. Khadas VIM4 and Radxa Rock 5B both work fine with Home Assistant Container, but you will be hand-installing add-ons rather than getting them from the HAOS store. The Banana Pi BPI-F3 is not yet a sensible Home Assistant host - RISC-V Docker images for the major add-ons (ZWaveJS, Z2M, the Frigate NVR) are incomplete.

If Home Assistant is your primary use case, our complete Pi setup guide is the quickest path. We also have a separate add-ons walkthrough covering which extensions to install first.

Three recurring issues catch people out when they buy outside the Raspberry Pi ecosystem.

Cooling. The RK3588 boards all run hot under load - 70-80°C is normal with a passive heatsink, and they will throttle if you sustain heavy CPU work without active cooling. Budget for the official active-cooling case or fan kit, which typically adds £15-£25 to the total. The Pi 5 with the official active cooler stays under 60°C in the same conditions.

Power supply. USB-C PD with quirks: the RK3588 boards expect 5V/4A or 12V/2A and refuse to boot on lower wattage chargers. The Pi 5 has its own official 27W USB-C PSU. Khadas VIM4 ships with a power supply in the box. Banana Pi BPI-F3 uses standard 5V/3A USB-C and is the most forgiving on power.

Storage and boot. Pi 5 boots from microSD or NVMe via a HAT. The RK3588 boards generally boot from a separate eMMC module (£20-£30 add-on) or an NVMe SSD - much faster than microSD but it pushes the total cost up. N100 mini-PCs ship with NVMe storage already installed.

Three boards are worth tracking if you have the patience to wait on a purchase decision.

Raspberry Pi 5 16GB Compute Module variant. The Pi Foundation confirmed at the Pi Day 2026 announcement that a Compute Module 5 variant in the 16GB tier will ship in Q3 2026, opening up the official Pi ecosystem to industrial-style carrier boards that today have to be hand-rolled around third-party SoCs. UK availability follows the usual 4 to 6 week lag behind US launch.

Rockchip RK3688 first-generation boards. Rockchip's roadmap lists a next-generation SoC with a stronger 6 TOPS NPU and DDR5 support; Radxa and Orange Pi traditionally release boards within 6 months of a Rockchip silicon launch. Whether that lands in 2026 or slips to early 2027 is the open question. If you specifically want a board for local AI inference, this is the one to wait for - the existing RK3588's 6 TOPS NPU is already showing its age for modern models.

RISC-V successors to the BPI-F3. The Banana Pi BPI-F3 is the current credible RISC-V board, but multiple Chinese vendors have announced successors using newer SpacemiT and StarFive silicon for late-2026 / early-2027 delivery. The category is still firmly in the 'curious tinkerer' bracket - RISC-V software support is improving but is at least two years behind ARM for everyday Linux desktop use.

For a buyer making a decision today, none of this should delay the purchase: the Pi 5 and the boards on this list are mature enough that waiting six months buys you optionality, not a fundamentally different product.

The Raspberry Pi is no longer the only sensible answer for a home single-board computer project. The Orange Pi 5 Plus and Radxa Rock 5B are genuinely faster boards at modest premiums; the Khadas VIM4 is the best media-decode option; and an N100 mini-PC at £140 quietly outclasses all of them for general-purpose Linux server work.

That said, the Pi 5 stays at the top of our recommendations for first-time buyers and anyone whose project leans on GPIO or HAT add-ons. The ecosystem advantage is real - every tutorial on this site assumes a Pi sitting on your desk. Pick a Pi 5 for compatibility, an Orange Pi or Radxa for power, a Khadas VIM4 for media, a Banana Pi BPI-F3 for the future, or an N100 mini-PC if the project lives entirely in Docker.

Once you have picked the board, our weekend home-server build guide walks through the rest of the setup, and the Pi-hole introduction is the easiest first project to put on it.
