Isembard opens £750,000 Milton Keynes manufacturing factory.

Isembard opens £750,000 Milton Keynes manufacturing factory. October 16, 2026 Isembard has opened a precision manufacturing factory in Milton Keynes. The £750,000 franchise operation is producing machined parts with two CNC machines, while a ten-machine expansion remains a future target. Isembard has opened a £750,000 precision manufacturing factory in Milton Keynes, with two CNC machines already producing components for the advanced engineering supply chain. The new facility operates under the company's franchise model and is intended to expand in stages as it builds its production workforce and machinery capacity. Muhammad Altalib and Guglielmo Salvatore Pellegrino own and operate the site at Caxton Court, Garamonde Drive, Wymbush. The 2,100 sq ft factory was established in just over three weeks and has begun dispatching parts, some of which are intended for space applications. Its opening is a separate development from Isembard's larger Southwark factory announced in September. The local operation is starting with two computer numerical control (CNC) machine tools. Isembard provides its franchisees with access to technology, training, branding, customer opportunities and accreditation support, while the franchise owners are responsible for operating the factory. Production management uses MasonOS, the company's digital system for coordinating manufacturing work. Isembard describes machining accuracy at the new location in terms of a fraction of the thickness of a sheet of paper. This is a broad description of precision, not a published tolerance specification for every component or machining process. Capability depends on the machine, tool, workpiece material, setup, measurement method and the geometry being manufactured. A CNC machining centre produces parts by controlling relative movement between a cutting tool and a workpiece, removing material along a programmed path. The result depends on more than the programmed geometry. Tool condition, cutting forces, workholding rigidity, temperature and the accuracy of the initial setup can influence the dimensions and surface condition of the finished part. The two installed machines give the operators capacity to make machined components, but the announcement does not identify their makes, axes, spindle arrangements or operating hours. Those details would be needed to establish which particular jobs the factory can manufacture without outside processing or additional equipment. Isembard's wider network serves aerospace, defence and robotics customers, and names Anduril, Babcock and Tekever among its customer relationships. Those relationships are at network level; there is no confirmation that this particular factory has received orders directly from each of those customers. The factory is already recruiting machinists and programmers, and its operators aim to grow to seven employees over the next year. The same plan envisages ten CNC machines and approximately 10,000 sq ft of premises. These are targets for future expansion, rather than current staffing, equipment or occupied space. Pellegrino, a biomedical engineer who previously founded digital orthodontics business Tie Cast, is general manager at the new location. Altalib previously founded technology business Seedlink and worked in venture capital. Both are now operating an industrial business in which production scheduling, quality and delivery performance must be maintained alongside commercial development. Under the franchise arrangement, MasonOS supplies a common software layer across otherwise separately operated manufacturing locations. Coordinating work digitally can assist with quoting, scheduling and recording production activity, but the existence of a shared platform does not establish that components can be transferred between factories without verifying equipment capability, process instructions and quality requirements. Before machining starts, a manufacturer must examine the customer drawing and determine how to make and inspect the component. Material selection, tooling, workholding, machine access and dimensional inspection all affect the route through production. Parts for demanding end uses may also require documented traceability and controls appropriate to the contractual specification. A network of smaller factories can place capacity closer to customers while distributing some of the cost and operational responsibility among local owners. It must also handle variation between sites: available machine envelopes, staffing, inspection facilities and experience may differ, even when administrative processes use the same software. The Milton Keynes location gives the franchise access to a regional engineering market covering motorsport, aerospace, robotics and specialist machinery. Its proximity to those sectors is a geographical advantage, but it does not itself demonstrate a confirmed order book or a specified production rate. Isembard intends its model to support additional UK manufacturing sites and opened a separate large operation in Southwark in September. The Milton Keynes factory differs in its franchise ownership, initial two-machine footprint and locally managed workforce. Maintaining a consistent production and quality system across these different facilities will be essential as the network expands. Expanding the new site from two to ten machines would increase its nominal equipment capacity, but the eventual output will depend on the mix of components, machining cycle times, labour availability, tool change requirements, inspection and the reliability of customer demand. Production capability will also need to be maintained as new operators and equipment are introduced. The immediate result is a working precision machining facility with two installed CNC machines and parts already being dispatched. Recruitment and the proposed move into larger premises remain subsequent steps, with no reported deadline for a particular throughput or revenue level at Milton Keynes.

London startup Isembard opens capital's largest factory since WWII, makes rocket and robot parts

Isembard, an automated manufacturing startup, has opened what it claims is the largest factory in London since the Second World War. Located off Old Kent Road in Southwark, the facility occupies a building originally redeveloped for last-mile logistics. The factory houses machines producing components for rockets, satellites, drones, and humanoid robots. The company's team includes veterans, former Amazon employees, and an ex-venture capitalist who have transitioned into factory ownership roles. The startup focuses on automated manufacturing, marking a significant industrial development in the UK capital. The facility represents a notable shift in London's manufacturing landscape, bringing aerospace and robotics production to an area previously designated for logistics operations.

Defence offers new front for Britain's office landlords.

Defence offers new front for Britain's office landlords. Knight Frank says firms want bases near research universities to recruit specialised talent Published Wed, Sep 30, 2026 · 03:00 PM * The managed Canary Wharf estate with its own security staff would likely be appealing to prospective defence occupiers, according to developer LS Estates CEO Mark Swetman. PHOTO: REUTERS [LONDON] Property investors in Britain are targeting defence clients to capitalise on growing spending on rearmament, including to occupy former bank offices in London's Canary Wharf financial district, real estate companies have told Reuters. A boom in defence technology - from drone programming to AI-enhanced cybersecurity - is stimulating demand for city centre offices and laboratories, on top of interest in traditional out-of-town industrial sites, the companies noted. "Defence used to be all about munitions, but that's totally changed. Now it's about these new technologies," said Jennifer Townsend, a partner at Knight Frank, adding that defence firms increasingly wanted to be near British research universities to attract talent. European countries are ramping up defence spending to meet tougher Nato targets, creating demand for 37 million square metres over seven years - equivalent to roughly 5,200 football pitches - Savills estimates. In Britain, up to three million square metres of industrial and logistics demand will be needed, plus nearly 250,000 square metres of additional office and R&D space, Savills forecasts. The latter is only about 2-1/2 times the space in HSBC's soon-to-be vacated Canary Wharf skyscraper, but a boost for a sector recovering as companies limit home working. Asean intelligence. Get insights into businesses across South-east Asia The "Golden Triangle" research cluster between London, Cambridge and Oxford is one of the areas benefiting, according to property agencies. In Canary Wharf - once dominated by banks - developer LS Estates told Reuters that it was sounding out defence and AI companies to occupy a refurbished nine-floor office once home to Credit Suisse support staff in response to changing demand. One of Britain's largest industrial landlords, Tritax Big Box, separately told Reuters that it has identified defence as a potential growth sector and begun sounding out potential occupiers. "There is sadly a significant boom in defence. The consequence is there's an awful lot of money being spent in R&D," LS Estates CEO Mark Swetman said, adding that the managed Canary Wharf estate with its own security staff would likely be appealing to prospective defence occupiers. The £100 million-plus (US$130 million-plus) refit of 17 Columbus Courtyard - backed by Singapore's sovereign wealth fund GIC and Oaktree - was originally targeted at life sciences firms with up to 60 per cent of the space earmarked for laboratories, but Swetman added that interest from that sector had been lower than expected in the short term. The high-spec space featuring reinforced floors, access to backup power and advanced ventilation is now seen as a potential fit for defence and AI firms, Swetman explained. Surging demand from defence occupiers means offices need tighter security and resilience, while some firms were targeting space in Westminster to be close to political decision makers, said Julian Woolgar, a partner at Knight Frank. Earlier this month, defence components maker Isembard opened what it said was London's largest factory since World War II in the city's Southwark district. The Ministry of Defence (MOD) meanwhile recently opened the largest indoor drone testing facility in Europe in a Panattoni-developed warehouse in Swindon. One of the world's largest privately owned developers of industrial real estate, Panattoni said that it was in active discussions with defence companies for space nearby as it redevelops a former Honda car plant. "Suppliers to the MOD like to cluster, like the Formula 1 cluster in Oxfordshire," pointed out James Watson, Panattoni's head of development for Southern England and London.

Isembard appoints Pip McKenzie as Chief Commercial Officer to scale its factory franchise network. 28 September 2026 10:45 * Isembard, the manufacturing company, has appointed a senior executive with global franchise experience to scale its commercial expansion across the United Kingdom, Europe, North America, and new markets. * Pip has executive experience from McDonald's, KFC, Yum! Brands and Gong Cha. * Isembard has grown from four factories to 16 already in 2026 * Isembard combines precision manufacturing, Mason OS, its agentic operating system, and franchisee factory ownership to rapidly expand component manufacturing capacity for aerospace, defence, robotics, and energy. Credit: Isembard Pip McKenzie, Chief Commercial Officer at Isembard, Isembard, the manufacturing company, has appointed Pip McKenzie as Chief Commercial Officer. She will lead the next phase of growth for its manufacturing franchise network across all markets. McKenzie brings deep experience from some of the world's most recognised franchised brands, including McDonald's, KFC, Yum! Brands and Gong Cha. Previously at Gong Cha, McKenzie delivered record transactional growth with master franchise agreements in 21 new countries and 3 US states. As Chief Commercial Officer, she will lead the development of Isembard's franchise platform internationally, establishing the partnerships, systems and the commercial framework needed to scale the network while maintaining world-class operational standards. Isembard is the only manufacturer to operate a factory franchise model. Owners run their own factory, while Isembard provides customer contracts, training, and MasonOS, its agentic operating system, which handles setup, quoting, scheduling, supply chain, production, quality control, and delivery. Franchising opens ownership to individuals who have the drive to run their own business but not the systems to do it alone. It has also drawn owners from well beyond traditional routes, including veterans, tech workers and successful multi-brand franchisees. The franchising model has played a key role in Isembard's growth: 16 factories are now trading, up from four at the start of 2026, including its new global headquarters and factory in Southwark, central London - the largest factory to open in the capital since the Second World War. Isembard is targeting 100 owned and franchisee factories across the UK alone by the end of 2028, a programme expected to create 2,200 high-skilled jobs. Pip McKenzie, Chief Commercial Officer at Isembard, said: "Re-industrialising the West is one of the defining opportunities of our generation. It requires a scalable model that enables exceptional operators to build world-class manufacturing businesses. By combining precision manufacturing expertise, proprietary Mason OS software and a proven franchise system, Isembard has created exactly that. I am joining to accelerate Isembard's expansion across the UK, Europe and North America and help redefine how advanced manufacturing scales globally." Alexander Fitzgerald, Founder and CEO of Isembard, said: "We are building a generational business. We therefore need generational talent. Pip's experience working for some of the world's most successful franchisors provides us with the expertise to support the next phase of growth. We'll soon Pip all other franchise systems to the post!"

Isembard launches its Largest Factory, feeding into Alloyed's metal AM pipeline.

Isembard launches its Largest Factory, feeding into Alloyed's metal AM pipeline. British software-first manufacturing startup Isembard opened its new global headquarters and factory in Southwark, central London, on September 14, 2026, calling it the largest factory to open in the capital since the Second World War. The launch caps a year in which the company grew from 4 factories to 16 across the UK, Europe, and the US, alongside a tenfold year-over-year revenue increase, and comes as Isembard prepares to raise additional funding to support further global expansion. The Southwark site will serve as both Isembard's head office and a working precision factory, producing components for aerospace, defence, and robotics customers including Anduril, Babcock, and Tekever. Targeting a market small businesses are ageing out of Isembard's expansion is built around a specific structural problem in component manufacturing, a market the company values at $1.8 trillion a year but says is dominated by small businesses that account for 95% of production and are rapidly disappearing. The average owner in that segment is over 65, and 40% plan to retire within five years, a wave of retirements the company argues is colliding with rising demand from aerospace, defence, energy, and robotics firms driven by re-shoring and higher spending on critical industries. Isembard's response combines owned factories with a franchise model, layered with a proprietary operating system called MasonOS that automates quoting, scheduling, production, and quality control across the network. The approach is meant to let experienced operators run high-performance manufacturing businesses from day one, using Isembard's technology, brand, engineering standards, and existing customer demand rather than building all of that from scratch. Milling, turn-mills, and wire EDM, with software built on top The Southwark factory houses 3-axis and 5-axis milling machines, turn-mills, and wire electrical discharge machines, alongside a climate-controlled metrology lab for precision inspection. Isembard designed the office to overlook the factory floor through floor-to-ceiling windows, giving its software and robotics engineers a direct view of production as they develop MasonOS and the company's forthcoming robotics technology. Headcount at the Southwark HQ is expected to grow from 35 today to 200 by the end of 2027, spanning production, software, manufacturing, and robotics automation engineering. The location itself carries some intentional symbolism: Southwark was historically one of London's manufacturing centres, home to foundries, engineering works, printworks, and tanneries, and is where Isambard Kingdom Brunel, the company's namesake, worked early in his career driving the Thames Tunnel out from Rotherhithe. Isembard and Alloyed: a supplier inside an AM company's supply chain Isembard doesn't 3D print itself, its confirmed equipment across factories is entirely subtractive, built around CNC milling, turning, and wire EDM. But it isn't disconnected from the additive manufacturing industry either. Among the customer stories featured on Isembard's own capacity page is Alloyed, the Oxford-founded metal additive manufacturing company, formerly OxMet Technologies, that designs alloys computationally and produces qualified metal components through its own AM production stack. Alloyed's Chief Engineer, Charlie Pearson, is quoted praising Isembard directly: "Isembard has proven to be an exceptionally capable manufacturing partner. Their team rapidly understood our technical requirements, iterated on solutions with pace, and delivered complex precision products to a standard we could trust." That places Isembard as a precision-machining supplier inside at least one AM company's broader manufacturing chain, even though the parts Isembard itself cuts are machined rather than printed. Part of a wider UK reindustrialisation push Isembard is targeting 100 owned and franchisee factories across the UK alone by the end of 2028, a plan the company says would create 2,200 high-skilled jobs. The announcement lands alongside the UK government's Defence Investment Plan, which commits close to £300 billion and names sovereign capability, autonomous systems, and resilient supply chains among its priorities. That push has increasingly leaned on additive manufacturing specifically as one of its core tools, not just conventional machining. The Ministry of Defence's own Defence Advanced Manufacturing Strategy identified 3D printing as crucial to its roadmap, citing a DIU-commissioned finding that printing 15% of the defence inventory could save £110 million over 15 years. That policy has already translated into hardware on the ground: Rheinmetall BAE Systems Land uses 3D printers extensively across Challenger 3 and Boxer production at its Telford site, backed by over £56 million in investment, while Rolls-Royce opened an MOD-backed Additive Manufacturing Development Cell in Bristol built around what defence officials have called a "factory to foxhole" logic. Isembard founder and CEO Alexander Fitzgerald framed the Southwark opening in the same terms: "Manufacturing is the origin of our security, prosperity and sense of purpose as nations. No one has opened a factory like this in London since the Second World War, and that tells you how far our industrial base has been allowed to shrink." Business Secretary Jonathan Reynolds welcomed the move as consistent with government policy: "This is exactly what reindustrialising Britain is all about. Bringing manufacturing back into the UK, backing our critical industries and creating highly skilled jobs across the country." Isembard's own factory network is built on conventional precision machining rather than 3D printing, but it's opening into an industrial base where additive manufacturing has become one of the load-bearing technologies of the reindustrialization effort and where at least one of its own customers is building that capability directly. 3D Printing Industry is inviting speakers for its 2026 Additive Manufacturing Applications (AMA) series, covering Energy, Healthcare, Automotive and Mobility, Aerospace, Space and Defense, and Software.
