Welcome to the first edition of the Robot AutoTrader monthly UK robot market roundup. Our plan is to publish this series on the first week of every month, giving UK buyers and sellers the most current available view of used robot prices, listing volumes, regulatory developments, and market-moving news.
September is a meaningful month to launch this series. The UK academic and research year begins, bringing fresh demand for laboratory robots and development platforms. Post-summer inventory often moves briskly. And the Q3 product announcement season from major robot manufacturers creates ripples in the used market that smart buyers and sellers need to understand.
Here is the full September 2026 picture.
Market Temperature: Humanoid Price Index
The Robot AutoTrader resale index tracks used robot pricing across categories. Here is the September 2026 snapshot across key humanoid categories:
NAO (SoftBank Robotics, v5/v6): Used prices in the range of £3,200-5,800 depending on condition, firmware version, and included accessories. Software support for older versions has become limited, which is putting downward pressure on v5 units. V6 units in good condition with a recent service history are holding value better.
Pepper (SoftBank Robotics): The commercial customer service use case never scaled as SoftBank hoped, and a significant number of Pepper units have returned to the market from retail and hospitality deployments. Used prices: £4,500-9,000 depending on condition and included tablet hardware. Units with documented low hours of operation and recent battery replacement command a premium.
Unitree G1: The first used G1 listings are appearing in the UK at approximately £13,500-15,000 - roughly 75-85% of original retail. Volume is very low (fewer than five UK listings visible at time of writing) and pricing is still finding its level. The G1's active development ecosystem and ongoing software updates are supportive of residual values. See our full Unitree G1 price guide for context.
Boston Dynamics Spot: Used Spot units remain expensive, typically £18,000-28,000 depending on generation, condition, and included arm attachment. Boston Dynamics' active refurbishment programme and strong lease market mean clean used units are absorbed quickly. Listings do not last long.
Research/custom platforms (Nao-compatible, ROS-based platforms): Highly variable. Condition and documentation matter enormously. Undocumented platforms with unclear provenance are difficult to price and tend to sit.
What Sold This Month: Category Breakdown
Robot vacuums continue to represent the highest volume of completed transactions on the Robot AutoTrader platform. Consumer awareness and price accessibility make this the broadest market. iRobot Roomba (various models), Roborock, and Ecovacs units dominate. The used robot vacuum market is functioning well - strong buyer demand, reasonable supply, transparent pricing.
Robot dogs are showing the strongest growth in listing and sale volume. Unitree Go2 units are appearing in numbers following strong new unit sales in H1 2026. The Go2 is accessible (new pricing around £1,500-2,500 for consumer editions) and appeals to developers, researchers, and enthusiasts who find Spot prohibitively expensive. Used Go2 units at £1,200-1,800 are moving quickly.
Industrial cobots - primarily Universal Robots UR3/UR5/UR10 series and Fanuc collaborative models - represent steady mid-market volume. September's back-to-work seasonality typically supports Q4 capital equipment decisions. Buyers in September are often researching for purchases they will execute in Q4 or Q1 next year.
First humanoid listings - this is the emerging story. The first consumer-category humanoid listings (primarily NAO and Pepper) have been joined in 2026 by the first Unitree G1 listings. Volume is small but the category is growing. We expect humanoid listing volume to grow significantly through 2027-2028 as early adopters cycle through their first units.
> Quick win: If you are considering a used robot dog (Go2 or similar), September and October are typically good buying months before the pre-Christmas demand surge. Sellers who purchased in Q1-Q2 2026 are beginning to list units, and the market has not yet tightened for the gifting season. Browse robot dogs.
New Model Announcements Affecting Used Prices
The Q3 2026 announcement period has been active. Buyers and sellers of used robots should be aware of how new model announcements affect the used market.
The general principle: When a manufacturer announces a significantly improved successor model, earlier model used prices typically soften within 60-90 days as owners of the earlier model anticipate reduced demand, and as buyers who were considering the earlier model delay to evaluate the new one.
Unitree: Unitree has continued its rapid iteration cadence. Any announcement of a G1 successor or enhanced G1 Pro version in Q3-Q4 2026 would put modest downward pressure on current used G1 pricing. First-generation unit owners who are considering selling should watch Unitree's announcements closely.
Universal Robots: UR has been relatively stable in its product roadmap in 2026. The UR20 and UR30 (larger payload cobots) are established in the new market; their entrance has slightly softened values for used UR10 units at the upper payload range, but the UR5 and UR10 used market remains healthy.
Boston Dynamics: Spot remains the reference platform for mobile inspection robots with no directly competitive successor announced. Used Spot prices are firm.
For detailed tracking of how announcements affect valuations, the Robot AutoTrader resale index updates monthly.
UK Import and Regulatory Update
UKCA marking: Post-Brexit, robots destined for commercial use in regulated UK environments require UKCA marking (the UK equivalent of CE marking). Consumer-grade robot vacuums and toys do not require UKCA. Industrial robots, cobots, and platforms used in commercial settings where machinery safety regulations apply do. When buying used equipment that was originally CE marked, check whether the seller has documentation supporting UKCA compliance or whether this is something you will need to address.
Customs duty: The UK Global Tariff applies a 3.7% MFN rate to most industrial robots from China. Consumer robots and robot toys attract different rates depending on classification. There are no additional tariffs or sanctions on Chinese consumer robots in the UK as of September 2026, though this is an area of active policy discussion following US actions. See our dedicated piece on FCC robot concerns and what UK buyers need to know for detail.
UK AI strategy: The UK government has continued to position the UK as a permissive environment for AI and robotics development, with the AI Safety Institute focused on frontier AI risks rather than consumer robotics. No specific robot deployment regulations affecting used robot buyers have been introduced in Q3 2026.
Data protection: Robots with camera and sensor systems that process personal data in commercial environments remain subject to UK GDPR. The Information Commissioner's Office has published updated guidance on AI systems including robotic systems. Commercial buyers deploying camera-equipped robots in workplaces should have a data protection impact assessment in place.
Buyer's Tip of the Month: September is Research Season
September marks the start of the UK academic year. Universities, research labs, and technical colleges are making purchasing decisions for the year ahead. This creates genuine competition for good used research robots (NAO, Pepper, mid-range cobots) and can push prices up during September and October.
For buyers: if your purchase is not time-sensitive, the October-November window often offers better value as the initial September research-season demand settles. January is historically the weakest month for used robot prices (post-Christmas, pre-new-year budgets) and can offer good deals.
For buyers who need equipment for Q4 projects: September remains a fine time to buy, just be aware you are buying into seasonal demand. Check the resale index for the most current price benchmarks before making an offer.
> Quick win: University equipment sales and institutional surplus auctions are an underused source of used research robots in the UK. Check JISC (the Joint Information Systems Committee) surplus listings, university procurement portals, and government surplus auctions (government-surplus.co.uk) alongside the Robot AutoTrader marketplace.
Seller's Tip: What to List Now vs Hold
List now if you have: NAO or Pepper units. The research-season demand window is open. Pepper units from retail deployments being cleared now face competition from other sellers in the same position - getting listed early in the window captures the best of the demand.
List now if you have: Clean, well-documented cobots with service history. Q4 capital equipment decisions are being made by UK manufacturers and engineering businesses. October is when the purchasing conversations become purchasing orders.
Consider holding if you have: Early-generation robot dogs (first Spot generation, older Unitree A1 units). The market for these is softening as newer generations are well established. Unless you need the cash now, waiting for a buyer who specifically values the older platform (for parts, for education, for hobby use) may deliver a better price than selling to the general market at current levels.
For any robot you are selling: good photography and clear documentation of working condition, software version, and included accessories are the biggest single determinant of achieved price vs listing price. Read our full guide on how to sell your robot in the UK for the complete process.

What to Watch in October 2026
- Unitree product announcements: any G1 Pro or successor reveal will affect current G1 used pricing
- UK Autumn Budget implications for capital allowances and R&D tax credits
- IREX (International Robot Exhibition) in Tokyo - typically a November event that previews the following year's commercial launches, with used market implications for current-generation models
- Amazon and Ocado UK logistics announcements: deployment scale affects secondhand availability of their robot systems as they upgrade
We will cover all of these in the October 2026 roundup. Browse the current Robot AutoTrader marketplace for September's available listings.
Frequently Asked Questions
What is the most popular robot category in the UK used market in 2026? Robot vacuums remain the highest volume category by unit count, driven by mainstream consumer adoption. Robot dogs (Boston Dynamics Spot, Unitree Go2) are showing the fastest growth in listing volume. The first consumer humanoid listings are beginning to appear.
Are used humanoid robot prices rising or falling in 2026? Early-generation humanoids (NAO, Pepper) have seen continued depreciation as they age out of active support and newer alternatives enter the market. Research-grade humanoids in good condition have held value better. The Unitree G1 is too recent to show a clear used price trend, but initial used listings are appearing around 70-80% of original retail.
Is September a good time to buy a used robot in the UK? September represents the start of the UK academic and research year, which historically increases demand for laboratory and research equipment including robots. Sellers listing in September typically achieve slightly better prices than in midsummer. Buyers looking for value may find better deals in October-November as the initial September rush passes.
What UK regulatory changes affect robot imports from China in 2026? Post-Brexit, robots imported from China to the UK require UKCA marking for commercial use in regulated environments. Customs duty on industrial robots from China to the UK sits at 3.7% MFN rate. There are no specific UK sanctions or import restrictions on Chinese consumer robots as of September 2026, though the US FCC data security discussion has raised awareness among UK procurement teams.
