Cutting-edge R&D, Cleanrooms, Offices, Light Engineering & Lab Space at Harwell Campus

Ideal for both start-ups and more established businesses, Zephyr’s high-profile location on the Harwell Campus puts you at the heart of the scientific community. Along with R&D offices that would suit companies with a technology-focus, Zephyr also offers suites for light engineering, assembly, clean rooms, and lab space for rent. Delivered as a customisable shell, choose from full fit-out or pre-fitted units – available from 279 sq m (3,000 sq ft). The first floor can also be modified to suit your business.

Floor-to-ceiling windows fill the entrance and levels above with natural light – adding to the welcoming atmosphere for employees and clients – while loading door access, on-site car parking and the availability of external compound areas take care of everyday operations.         Three-phase electricity and Harwell’s reliable broadband keep you connected; meanwhile, your proximity to the Quadrangle development caters to the more social side of networking.

Life at Harwell

Companies thrive when their people do. Harwell is designed to bring out the best in your teams, whether you’re a two-person start-up or a FTSE-listed multinational. Our campus combines beautiful countryside with city-level facilities, including on-site food and drink and numerous sports clubs, covering rugby to archery. The facilities are set to expand too, with cutting-edge conference spaces, a new hotel, and contemporary homes in our residential quarter all due to open soon.


Harwell is located in beautiful countryside just south of Oxford, one of the fastest growing cities in the UK.

Oxford city centre is just over 20 minutes, drive away, Heathrow is 55 minutes by road, and nearby Didcot Parkway station connects you to London Paddington in just 42 minutes. The launch of Crossrail and the upgrade to the Didcot Parkway Line mean it will soon be possible to reach central London Underground stations in under one hour.

There is a shuttlebus service through the day to Didcot Parkway and Oxford.


At Harwell, your neighbours are some of the most innovative science and engineering organisations in the world. Our collaborative approach supports companies of all sizes, and companies here have access to a wide range of practical business support and funding, from grants and tax breaks to venture capital opportunities. What’s more, being at the centre of the Oxfordshire innovation ecosystem allows you to easily attract and recruit talented candidates from a wide range of fields.

Network & collaboration

Harwell is your gateway to a lively, 6,000-strong community – as well as a unique opportunity for holding talks with leading thinkers, scientists and senior politicians from across the globe. Make new connections at Connect Harwell, our central forum which links up over 200+ companies at inspiring events. And collaborate in our range of meeting room and conference spaces. The campus also organises free Special Interest Groups and Forums, C-Suite symposiums, and hosts university placements and apprenticeships for students in Science, Engineering, IT and Business.

Our clusters

One of Harwell’s greatest strengths is the way it brings people together. And basing yourself or your organisation here gives you easy access to the UK’s most unique professional clusters: Space, Quantum, Health Tech and Energy Tech. Each cluster gathers businesses, organisations and people from across the campus and the UK to share ideas, take risks and attract funding – and ultimately, solve the biggest problems facing our planet.

A healthy place to work

Where wellbeing comes first

Wildflower areas. Fresh air. Leafy walkways and views out to the rolling Oxfordshire countryside. Located in an Area of Outstanding Natural Beauty, Harwell is as beautiful a place for your employees to work as it is inspiring – giving easy access to green space, nature, and various walking and bike trails. A real pleasure to stroll around, the campus also runs a Bicycle Loan Scheme for staff to hire manual and electric bikes.
