Why Sell Your Used PC Parts Now?
The UK used PC parts market in 2026 is one of the strongest it has been in years. Current-generation hardware — RTX 40-series GPUs, Ryzen 7000 and 9000 CPUs, DDR5 memory — still commands strong resale prices because new stock remains expensive. A used RTX 4070 Super currently fetches £380–£430 on most platforms, and Ryzen 7 7700X processors regularly sell for £180–£210.
But here is the catch: prices always dip when new generations launch. NVIDIA's RTX 50-series is now hitting shelves, and AMD's Zen 5 refresh is confirmed for Q3 2026. Every week you wait, your parts depreciate. Historically, last-generation GPUs lose 15–25% of their resale value within six weeks of a new launch. CPUs fare slightly better at 10–15%, but the direction is always down.
The optimal selling window is right now — before the flood of upgraders dumps their old hardware onto every marketplace at once, cratering prices. If you have parts to sell, this guide will show you exactly where to list them for the best return.
Where to Sell Used PC Parts in the UK
The best place to sell used PC parts in the UK in 2026 depends on what you're selling, how fast you need the money, and how much effort you're willing to put in. Here is an honest breakdown of every major platform available to UK sellers.
Koukan
Koukan is the UK's dedicated marketplace for used PC parts. Unlike general marketplaces, every buyer and seller is here specifically for computer hardware, which means faster sales, more knowledgeable buyers, and fewer timewasters. The platform is purpose-built for the UK market — all prices are in pounds, all shipping is domestic, and the community understands what a "used but never mined" GPU actually means.
Koukan is built by PC enthusiasts for PC enthusiasts. Listings include spec fields tailored to hardware (VRAM, socket type, clock speeds), seller ratings are hardware-specific, and the buyer protection system is designed around the unique risks of second-hand component sales. If you're selling PC parts specifically, it's the smartest starting point.
eBay UK
eBay is still the biggest general marketplace in the UK for used goods, and PC parts are no exception. Millions of buyers, strong search visibility, and a mature platform. The problem? Fees eat your margin, buyer-friendly dispute resolution can leave sellers exposed, and you will compete with hundreds of near-identical listings.
On a £400 GPU, eBay's fees cost you roughly £51. That's money you simply keep on a zero-fee platform. eBay also has a well-documented problem with "empty box" return scams and INAD (Item Not As Described) claims filed in bad faith. Sellers with low feedback scores are particularly vulnerable.
Facebook Marketplace
Facebook Marketplace is a popular choice for local, in-person sales. There are no seller fees for local pickup, which makes it attractive on paper. In practice, it's plagued by no-shows, lowballers, and scam buyers. There is no meaningful buyer or seller protection for local transactions.
Facebook Marketplace works best for cheap, bulky items where you want cash in hand and don't mind meeting strangers. For valuable PC components like GPUs and CPUs, the lack of any dispute resolution makes it risky. If someone pays you counterfeit notes in a car park, you have no recourse.
Gumtree
Gumtree was once a strong competitor for local sales in the UK, but traffic has declined significantly since 2022. Listings sit longer, and the buyer pool is smaller and less tech-savvy than it used to be. It still works in larger cities like London, Manchester, and Birmingham, but outside those areas expect a slow experience.
Gumtree is worth a crosspost if you're already listing locally, but don't rely on it as your primary channel. The platform has seen minimal investment and the user base is shrinking year-on-year.
CeX (Cash or Voucher)
CeX is the fast-food option: walk in, hand over your hardware, walk out with cash (or store credit). It's the fastest way to sell PC parts in the UK — but you pay dearly for that convenience. CeX buy prices are typically 30–50% below what you'd get selling privately. They need to resell at a profit, and their margins are aggressive.
Example: CeX currently offers around £240 cash for an RTX 4070 Super that sells for £400+ privately. That's £160 you're leaving on the table. CeX is only worth considering if you need money today and cannot wait even a few days for a private sale.
Reddit r/HardwareSwapUK
The subreddit r/HardwareSwapUK is a niche but active community of UK hardware enthusiasts who buy and sell components directly. Posts follow a strict timestamped photo format, and PayPal Goods & Services is the standard payment method. Buyers here are knowledgeable — they know fair prices and will call out overpriced listings instantly.
HardwareSwapUK is excellent if you're already active on Reddit and comfortable managing your own shipping and PayPal invoices. It's less suitable for casual sellers or those who want a simple, guided selling experience.
| Platform | Fees | Sell Speed | Protection | Best For |
|---|---|---|---|---|
| Koukan | 0% | 1–5 days | Full | Best overall for PC parts |
| eBay UK | ~12.8% | 3–10 days | Strong (buyer-biased) | Maximum exposure |
| Facebook Marketplace | 0% | 1–14 days | None | Local cash sales |
| Gumtree | 0% | 7–30 days | None | Crosspost only |
| CeX | 30–50% haircut | Instant | N/A | Need cash immediately |
| r/HardwareSwapUK | ~3% (PayPal) | 1–7 days | PayPal G&S | Enthusiast-to-enthusiast |
How to Price Your Used PC Parts
Overpricing is the number one reason listings sit unsold for weeks. Underpricing means you leave money on the table. Here is how to find the sweet spot.
- Check eBay sold listings. Search for your exact model on eBay UK, then filter by "Sold items". This shows you what buyers actually paid, not what optimistic sellers are asking. Note the average of the last 10–15 sales.
- Compare Koukan marketplace prices. Browse active listings on Koukan for the same part. If three RTX 4070 Supers are listed at £410, £420, and £400, you know the market range.
- Price 10–15% below the retail used average for a fast sale. If the average sold price is £400, listing at £350–£360 will generate interest within hours. If you're not in a rush, match the average and wait.
- Factor in condition honestly. Cosmetic damage, missing accessories, or heavy use (especially mining) should drop your price by 10–20% further. Buyers will negotiate if they spot any undisclosed wear.
- Account for platform fees. On eBay, a £400 listing nets you ~£349 after fees. On Koukan, you keep the full £400. Price accordingly — you can often offer a lower sticker price on Koukan and still net more.

How to Create a Listing That Sells Fast
A good listing is the difference between selling in one day and relisting for a month. Here is what the fastest-selling listings have in common.
Take Proper Photos
Use natural daylight or a well-lit desk. Show all angles: front, back, connectors, and any ports. For GPUs, photograph the PCIe gold fingers (buyers check for corrosion or burn marks), the fan blades (dust build-up signals maintenance history), and the backplate. For CPUs, photograph the pins or contact pads clearly. Blurry phone photos in dim lighting kill buyer confidence instantly.
Write an Honest Description
Include the exact model name (e.g., "ASUS TUF RTX 4070 Ti Super OC 16GB", not just "4070"). Mention how long you've owned it, what you used it for (gaming, rendering, mining — be honest), and any cosmetic marks or issues. Listings that disclose minor flaws upfront actually sell faster because buyers trust them more.
Include Specs and Benchmarks
For GPUs, include the VRAM amount, boost clock, and a GPU-Z screenshot if possible. For CPUs, note the core count, boost frequency, and whether it's been overclocked. If you ran benchmarks (TimeSpy, Cinebench), include the scores — it proves the part works and gives buyers confidence. Storage drives should include a CrystalDiskInfo health screenshot.
Mention Box and Accessories
Original packaging adds real value — typically 5–10% more on GPUs and CPUs. If you have the original box, anti-static bag, manuals, or bundled accessories (SATA cables, fan splitters), mention them. "Boxed with all original accessories" is a proven selling point.
How to Ship PC Parts Safely in the UK
Damaged goods in transit are the fastest way to lose money and reputation. PC components are fragile, static-sensitive, and often oddly shaped. Here is how to ship them properly.
GPU Shipping
GPUs are the most damage-prone component in transit. Always use an anti-static bag — never wrap a GPU in regular plastic or newspaper. Place the bagged GPU inside its original box if you have it, or use a snug-fitting box with at least 5cm of padding on every side. For high-value cards (£300+), double-box: place the inner box inside a larger outer box with additional padding. This protects against courier drops and compression.
CPU Shipping
CPUs must ship in a clamshell case — the plastic holder they came in, or a replacement from Amazon (under £2). Never ship a bare CPU in a padded envelope or loose in a box. The pins on AMD AM4/AM5 processors and the LGA contacts on Intel chips are incredibly fragile. One bent pin can render a £250 CPU worthless.
RAM and SSDs
RAM sticks and M.2 SSDs are small and relatively robust, but still need anti-static protection. Use an anti-static bag (or the original packaging) and a small padded envelope or box. For M.2 drives, a small plastic clamshell or even a well-padded letter can work, but tracked delivery is essential.
UK Courier Comparison
| Courier | Speed | Typical Cost | Insurance | Notes |
|---|---|---|---|---|
| Royal Mail Tracked 48 | 2–3 days | £4–£8 | Up to £100 | Reliable, most familiar to buyers |
| Royal Mail Special Delivery | Next day by 1pm | £7–£12 | Up to £500 | Best for high-value items (GPUs, CPUs) |
| Evri (formerly Hermes) | 3–5 days | £3–£6 | Up to £50 standard | Cheapest, but mixed reliability |
| DPD / DPD Local | Next day | £6–£10 | Up to £500 | Best tracking, time-slot delivery |
Insurance is non-negotiable for items over £50. If a courier loses or damages your parcel and you didn't insure it, you absorb the full loss. Royal Mail Special Delivery or DPD with enhanced cover are the safest options for GPUs and CPUs.
Getting Paid Safely
How you receive payment is just as important as where you sell. The wrong payment method can leave you with no recourse if something goes wrong.
Safe Payment Methods
- Koukan's built-in payment system — the safest option for PC parts. Payment is held in escrow until the buyer confirms receipt and satisfaction. If there's a dispute, Koukan mediates. You never share bank details with the buyer.
- PayPal Goods & Services — provides seller protection if you ship to the verified address with tracking. The ~2.9% fee is worth the protection. Always send a PayPal invoice — never accept "friends and family" payments from buyers (it strips both parties of protection).
Unsafe Payment Methods — Avoid
- Bank transfer (faster payments) — no buyer or seller protection. Once the money is sent, it cannot be reversed. Scammers prefer this method specifically because it's irreversible.
- Cryptocurrency — irreversible, untraceable for practical purposes, and a huge red flag. No legitimate PC parts buyer will insist on paying in crypto.
- Gift cards or vouchers — the hallmark of a scam. No exceptions. If someone asks you to accept Amazon gift cards as payment, block them immediately.
- Cash by post — obviously risky. Never accept physical cash sent through the postal system.
Frequently Asked Questions
Where is the best place to sell PC parts in the UK?
The best place to sell used PC parts in the UK in 2026 is Koukan. It charges zero seller fees, has a dedicated PC hardware audience, and includes built-in buyer protection and seller verification. For maximum reach at the cost of ~13% fees, eBay UK is the alternative. For instant cash at significantly reduced prices, CeX is an option.
How much do PC parts lose in value?
PC parts depreciate at different rates depending on the component type and market conditions. GPUs typically lose 15–25% of their value within six weeks of a next-generation launch. CPUs depreciate more slowly at around 10–15% per generation. RAM and SSDs hold value well unless a new standard arrives (e.g., DDR4 dropped sharply when DDR5 became mainstream). On average, expect a used PC component to retain 50–70% of its original retail price after one year of normal use.
Should I sell parts individually or as a bundle?
Selling parts individually almost always nets more money than bundling — often 20–40% more in total. A complete system sold as a bundle typically fetches less because buyers discount unknown components. The exception is matching pairs (e.g., a 2x16GB DDR5 kit) or a CPU + motherboard combo on the same socket — these can sell faster and for a slight premium when bundled together. If speed matters more than maximising revenue, a bundle can be the right call.
Do I need to wipe drives before selling?
Yes, absolutely. Before selling any storage device — SSD, HDD, or NVMe drive — you must securely erase all personal data. A simple "delete all files" or "format" is not sufficient; data can be recovered with free tools. For SSDs and NVMe drives, use the manufacturer's secure erase utility (e.g., Samsung Magician, Crucial Storage Executive) or a tool like Parted Magic. For HDDs, a single-pass zero-fill using DBAN is sufficient. Selling a drive with personal data on it is a serious privacy risk.
What PC parts sell fastest in the UK?
GPUs sell the fastest — a fairly priced current or last-generation graphics card (RTX 4060 Ti and above, RX 7800 XT) typically sells within 1–3 days on active platforms. CPUs are next, especially Ryzen 7000/9000 and Intel 13th/14th gen parts. DDR5 RAM kits sell quickly at the right price. The slowest sellers tend to be cases, older PSUs, and case fans — these often work better as local pickup sales.
Do I need to pay tax on selling used PC parts?
In the UK, HMRC's "trading allowance" gives you a £1,000 tax-free threshold per tax year for casual selling. If you sell your personal used PC parts and the total is under £1,000, you do not need to declare it. If you exceed £1,000, or if you regularly buy and sell hardware as a business, you may need to register as self-employed and report the income. This is not tax advice — consult HMRC's guidance or an accountant if you're unsure.
