Winchester Science Centre & Planetarium, Exclusive Hire

About Venue

Winchester Science Centre & Planetarium is a large-scale, experience-led event venue just outside Winchester that brings science, imagination, and a real sense of wonder into every gathering. This is a venue people remember, not just because of its size or setting, but because it feels genuinely different, playful, and sparks curiosity within adults and children alike.

The venue is particularly well suited to host conferences, brand launches, drinks receptions, gala dinners, award ceremonies, and end of year celebrations where you want guests to feel engaged from the moment they arrive. It works brilliantly for organisations looking to host something bold, memorable and full of surprises.

What really sets this venue apart is the support behind the scenes. The on-site team are experienced, friendly, and very used to helping organisers bring ambitious ideas to life. Exclusive hire options and premium touches make it easy to create a VIP feel, while flexible catering arrangements allow events to be tailored without feeling restricted. For planners, this means less stress, smoother logistics, and a space that adapts to your vision rather than the other way around.

In terms of location, the venue is easy to reach from Winchester and well connected to London and the wider South East. Ample on-site parking makes arrival simple for guests, while step-free access and wide open spaces ensure the venue feels welcoming and accessible throughout. It is a practical choice that still feels exciting, which is exactly why so many organisers return for their biggest events.

About this space:

Exclusive Hire gives you private use of the entire Winchester Science Centre & Planetarium for large-scale events of up to 1,000 guests, allowing organisers to design a fully immersive, multi-area experience within a single booking. This option is ideal for conferences, company away days, gala dinners, award ceremonies, and brand events that need scale, flexibility, and clear separation between different moments of the day or evening.

With exclusive access, events can flow seamlessly between exhibition floors, presentation spaces, dining areas, and outdoor zones, creating a sense of progression rather than a single static room. The central presentation area surrounded by 2 floors of interactive exhibits, works particularly well for receptions, networking, and experiential activations, while seated dining and theatre-style moments can be built in where required. Exclusive hire also allows greater control over branding, scheduling, and guest movement, making it easier to deliver a polished, well-managed event that feels cohesive from arrival to departure.

Interactive science workshops and shows can also be added to your event, led by our engaging Inspirer teams. A perfect add‑on for team engagement, networking, and creating standout moments at your event.
