Used KUKA Robots UK Buyers Guide 2026: LBR iisy, LBR iiwa and What to Check Before You Buy

Used KUKA Robots UK: The Complete 2026 Buyers Guide

Used KUKA robots for sale in the UK range from £5,000 for compact industrial arms to more than £40,000 for late-generation collaborative models, and the market is active enough in 2026 that buyers have genuine choice across payload classes and generations. KUKA is the most widely available industrial robot brand on the UK secondary market, sustained by a steady supply of pharmaceutical decommissions, university research returns, and automotive lease-backs across the full model range. This guide covers what each model costs used, which specifications to request from sellers, and the five inspection steps that separate a sound purchase from an expensive mistake.

This guide is for the UK buyer who has already decided KUKA is the right platform and wants to know how to buy a used unit with confidence. For buyers still weighing up cobot platforms, start with our used cobot buyers guide before returning here for KUKA-specific detail.

Used KUKA Robots for Sale in the UK: Models and Prices

KUKA is the most widely available industrial robot brand on the UK secondary market, with stock spanning lightweight cobots through to heavy-payload industrial arms. The following models represent the main options for UK buyers in 2026, with indicative used price ranges drawn from verified UK listings and trade sources.

KUKA LBR iisy (3 kg, 11 kg, 15 kg): The current-generation collaborative arm, introduced from 2021. Used prices range from £8,000 to £13,000 for the 3 kg variant and £11,000 to £17,000 for the 11 kg. Seven-axis force-torque sensing, 0.05 mm repeatability on the 3 kg, and IP54 sealing make it the preferred choice for pharmaceutical handling, electronics assembly, and precision inspection. The iisy runs on the KR C5 micro controller with KUKA's iiQKA.OS operating system. See the full KUKA LBR iisy specification for a complete payload and reach comparison.

KUKA LBR iiwa 14 kg: The previous-generation collaborative arm, now superseded in new sales but widely available on the used market from pharmaceutical and university research sources. Used prices range from £25,000 to £45,000 depending on age, accumulated cycle count, and whether Sunrise.OS application licences are included. University returns often carry low cycle counts alongside academic service records, making them strong value at the lower end of that range. See KUKA LBR iiwa 14 specifications for full technical data.

KUKA KR AGILUS: A compact, high-speed industrial arm available in 3 kg to 8 kg payload variants. The KR AGILUS is not a collaborative robot; safety fencing is required in production use. Used units start from £5,000 and deliver strong cycle times for electronics handling, packaging, and part transfer applications where human collaboration is not required. It represents the lowest-cost entry point to the KUKA platform and is well supported by UK system integrators.

KUKA KR QUANTEC: KUKA's heavy-payload industrial series, covering 90 kg to 300 kg capacity at reach up to 3.9 m. Used KR QUANTEC robots start from £10,000 and are well established in automotive body welding, palletising, machine tending, and large-part handling. Spare parts availability from KUKA UK is reliable across most variants in this series.

KUKA in 2026: What UK Buyers Need to Know

Ownership, Manufacturing, and Support

KUKA was acquired by the Midea Group, a Chinese appliance and automation conglomerate, in 2016. The acquisition caused concern among some European customers, but manufacturing remains in Augsburg, Germany, and the engineering organisation is intact. KUKA UK operates as a subsidiary with direct sales, service, and applications support. Spare parts availability for UK buyers is not materially affected by the ownership change, and CE and UKCA certification processes are unchanged.

For UK buyers, the practical implication is that KUKA's European distribution model operates normally. Authorised KUKA system partners (KSPs) provide integration and service across the UK, and the parts supply chain routes through KUKA Deutschland with standard delivery lead times to UK addresses.

The LBR Product Family

KUKA's collaborative arm range consists of three products relevant to UK buyers in 2026:

LBR iisy (3 kg, 11 kg, 15 kg): The current generation collaborative arm, introduced from 2021. Uses the KR C5 micro controller and iiQKA.OS operating system. Force-torque sensing in all seven joints. Repeatability of plus or minus 0.05 mm on the 3 kg variant. Designed for sensitivity-critical applications where contact with humans or delicate components is expected.

LBR iiwa (7 kg, 14 kg): The previous generation collaborative arm, now superseded by the iisy in most new sale contexts but still widely available used. Uses the KR C4 compact controller and KUKA Sunrise.OS. The iiwa established KUKA's collaborative robotics credentials in automotive and pharmaceutical sectors and remains a capable platform with strong integrator familiarity. Used units represent the majority of KUKA cobot stock on the UK market in 2026.

KR AGILUS: A compact, high-speed industrial arm (not collaborative) available in 3 kg to 8 kg payloads. Relevant context for buyers considering KUKA's industrial as well as collaborative range, but the AGILUS requires safety fencing and is positioned differently from the LBR range. It is faster and cheaper for high-throughput applications where human collaboration is not required.

Who Should Buy a Used KUKA Cobot

Right Applications

Used KUKA LBR iisy and LBR iiwa cobots are the right choice when the application demands:

Force-sensitive assembly: KUKA's joint torque sensing is among the most refined in the collaborative robot market. Applications involving insertion tasks, thread engagement, or assembly steps where controlled compliance is needed benefit directly from the LBR's native force feedback.

Pharmaceutical and medical device handling: The LBR iisy is designed for cleanroom-compatible operation. The smooth external surfaces, sealed joints, and IP54 rating (IP67 on specific variants) make it a practical choice for pharmaceutical sample handling, laboratory automation, and sterile packaging applications.

Electronics testing and inspection: The 0.05 mm repeatability on the LBR iisy 3 kg makes it suitable for PCB handling, connector insertion testing, and optical inspection alignment tasks where a standard cobot's tolerance would introduce measurement error.

University and research applications: The LBR iiwa has a long history in academic robotics research. KUKA's Sunrise.OS provides direct access to joint torque data and impedance control parameters that are essential for research into human-robot interaction, contact-rich manipulation, and learning from demonstration. Used LBR iiwa units with academic provenance are common on the UK market and typically have low cycle counts.

Who Should Not Buy a Used KUKA Cobot

Buyers without an integrator relationship: KUKA iiQKA.OS and Sunrise.OS are capable but less familiar to UK integrators than PolyScope (Universal Robots). If you do not already have a KUKA-experienced integrator lined up, or staff with Sunrise.OS or iiQKA.OS training, the path to production is longer and more expensive than with a UR cobot. Integrators who are comfortable with Universal Robots may not have KUKA experience, and finding the right partner can add weeks to your project timeline.

Buyers seeking the widest accessory ecosystem: The Universal Robots UR+ ecosystem has hundreds of certified end-effectors and accessories with guaranteed cobot compatibility. KUKA's equivalent programme is narrower. Grippers, vision systems, and force-torque sensors from major suppliers (Robotiq, OnRobot, Schunk) support KUKA cobots, but fewer options carry native KUKA certification, and some require additional integration work.

Applications prioritising speed over precision: If throughput is the primary requirement and force-sensing is not needed, a used UR10e or a KUKA KR AGILUS with conventional safety guarding will deliver better cycle times at lower cost.

UK Pricing: Used KUKA LBR iisy and LBR iiwa

Used KUKA LBR prices in the UK in 2026 reflect the narrower supply compared to Universal Robots. Expect the following ranges:

LBR iisy 3 kg: £8,000 to £13,000 used; approximately £22,000 new. Savings of 40 to 63% versus new are achievable from verified sources with service histories. Units from pharmaceutical or research deployments at under 30,000 cycles represent strong value.

LBR iisy 11 kg: £11,000 to £17,000 used; approximately £28,000 new. The 11 kg variant is less commonly available used in the UK, reflecting lower deployment volumes relative to the 3 kg version in most UK applications.

LBR iiwa 7 kg and 14 kg: £18,000 to £30,000 used; approximately £45,000 or more new. University research units are the most common source on the UK market and typically come with low cycle counts, academic service records, and (in many cases) Sunrise.OS licences included. Verify licence status carefully, as some academic Sunrise.OS installations are site-licensed rather than unit-licensed.

For reference, the Universal Robots Gen 7 announcement has increased used market availability of Gen 6 UR cobots in the UK, with used UR5e units now available from £8,000 to £15,000. KUKA LBR iisy units are priced competitively when the application justifies the platform.

These prices are hardware only. Budget for integration, end-effectors, safety assessment, and software licence transfers on top of the hardware cost.

What to Check Before Buying a Used KUKA Cobot

Step 1: Controller Log and Cycle Count

KUKA robots record operational history in the KR C4 or KR C5 controller. The steps to retrieve this data are:

Connect a laptop to the controller via the X66 service Ethernet port. Open KUKA.WorkVisual and navigate to the controller's diagnostic log. Request an export of the operating statistics file, which contains total operating hours, number of motion starts (the closest equivalent to cycle count), and fault history with timestamps.

On KR C5 controllers with iiQKA.OS, the web-based dashboard provides a summary view of operating statistics accessible from any browser on the same network segment. This is a useful quick check but does not replace a full WorkVisual log export for due diligence purposes.

Interpret cycle counts in context: a KUKA LBR iiwa used in an academic research lab may have accumulated 80,000 motion starts over five years, reflecting intermittent research use. The same arm in a pharmaceutical production line might reach 500,000 motion starts in two years. Motion starts per year and payload profile matter more than the absolute number.

Step 2: Software Licence Verification

KUKA software licences are serialised to the controller. Ask the seller for a complete list of installed software options before the physical inspection. Key licences to verify include:

KUKA.PLC mxAutomation: Allows a PLC to control the robot via a standardised function block interface. This licence is required for most production integration scenarios and is priced at several thousand pounds if not included.

KUKA.Sim: The offline simulation and programming environment. Useful for programming and testing without occupying the physical robot. Transfer is possible but requires KUKA involvement.

Sunrise.OS application licences (for LBR iiwa): The iiwa's Sunrise.OS supports application modules including KUKA.Sunrise.Servoing (real-time external setpoint control) and KUKA.ForceTorqueControl. Verify which application modules are licensed and whether they are unit-licensed or site-licensed.

Contact KUKA's software licensing team directly, or through an authorised KUKA system partner, to confirm licence transferability and obtain transfer cost estimates before agreeing a purchase price.

Step 3: Safety Configuration Export

KUKA cobots store safety configuration parameters in the controller. These parameters define safe speed limits, workspace monitoring zones, force limits for collaborative operation, and tool definitions. Request an export of the current safety configuration from the seller.

Review the safety configuration against your intended application before purchase. If the robot was configured for a specific payload and tool that you will not be using, the safety configuration will need to be recalibrated. Safety recalibration on KUKA LBR cobots requires KUKA.WorkVisual and, for CE/UKCA-compliant production use, a qualified engineer sign-off. Factor this into your integration budget if the existing configuration does not match your application.

Step 4: Gripper and End-Effector Compatibility

The LBR iisy uses an ISO 9283-compliant mechanical interface (tool flange) at the wrist. Major gripper manufacturers including Schunk, Robotiq, and OnRobot offer compatible products, but not all UR-compatible grippers will work without modification on KUKA cobots. Electrical connections for tool power and communication differ between platforms.

If you are purchasing used with a specific gripper or end-effector in mind, confirm electrical and mechanical compatibility with the gripper manufacturer's KUKA compatibility list before purchase. For research applications requiring a specific force-torque sensor, verify that the sensor's ROS or Sunrise.OS driver is current and supported.

Step 5: Physical Inspection Checklist

Beyond the electronic checks, the physical inspection should cover:

Joint backlash: With the controller in teaching mode and brakes released, manually move each joint through its range of motion. Noticeable play in any joint indicates bearing wear that may require service.

Cable management: Inspect the internal cable harness at each joint and the external teach pendant cable for wear. Cable failures are a common maintenance item on high-cycle-count units.

Controller cooling: Open the controller cabinet and inspect the cooling fans and filter. Blocked filters indicate the unit has been running in a dusty environment and may have experienced thermal stress.

Flange interface: Inspect the tool flange for wear, damage, or non-standard modifications. A damaged flange will require service before deployment.

Integration Costs and What to Expect

A used KUKA LBR iisy or LBR iiwa is a capable platform, but the hardware purchase is the beginning of the cost picture, not the end. Integration is consistently the largest cost item for UK SME deployments.

KUKA system partners in the UK will quote application-specific integration. For straightforward assembly or handling tasks with a defined end-effector, budget £10,000 to £25,000. For applications involving vision-guided positioning, pharmaceutical compliance documentation, or multi-robot coordination, £30,000 to £60,000 is realistic.

The narrower KUKA integrator network in the UK compared to Universal Robots means project lead times can be longer and day rates higher. For buyers in regions outside London, the Midlands, and the central manufacturing belt, finding a local KUKA-experienced integrator may require searching beyond the immediate area.

Buyers also considering Universal Robots should review our KUKA manufacturer profile for a side-by-side view of support infrastructure and used market supply.

Where to Find Used KUKA Cobots in the UK

The primary sources for used KUKA LBR cobots in the UK are:

Robot AutoTrader listings: Browse current used commercial and industrial robots listings including KUKA LBR iisy and LBR iiwa units from verified UK sellers. See the KUKA LBR iisy specs and pricing, KUKA LBR iiwa specs, and KUKA LBR Med database entries for full specification comparisons. All listings include seller verification and where available, controller log data.

KUKA authorised resellers: Several KUKA system partners in the UK trade used equipment alongside new sales. These channels typically offer refurbished units with warranty cover, priced higher than private market sales but with reduced technical risk.

University and research institution sales: UK universities with robotics departments decommission LBR iiwa units regularly, often with low cycle counts and academic documentation. These sales typically go through institutional procurement portals or direct contact with the research group. Units are sold without integrator support but are often in excellent mechanical condition.

Industrial auctions: Used KUKA cobots appear at UK industrial auctions, typically from manufacturing facility clearances. Prices can be lower than private market sales, but no service history is available and the buyer assumes full technical risk.

Summary: Is a Used KUKA Cobot Right for You?

A used KUKA LBR iisy or LBR iiwa offers genuine value for UK buyers in pharmaceutical handling, precision assembly, electronics testing, and academic research. The force-sensing capability, joint torque resolution, and repeatability of the LBR range are competitive advantages in sensitivity-critical applications that a UR cobot cannot easily match.

The conditions that make KUKA the right choice are specific: you need the torque-sensing capability, you have access to a KUKA-experienced integrator, and your application justifies the additional integration complexity compared to a UR deployment.

For buyers who do not meet those conditions, the broader UK integrator network, deeper used market, and lower total integration cost of Universal Robots UR cobots will typically produce a faster path to production. A used UR5e at £8,000 to £15,000 with a familiar PolyScope integration is the lower-risk route for most UK SME applications.
