At Eventologists, we specialise in event decor hire in the UK, event theming and bespoke decor installations that turn ordinary spaces into unforgettable experiences. So if you’re looking to pull off a jaw-dropping brand activation this autumn, you’re in the right place!

Below, we’ve rounded up five trending event themes for autumnal events that drive engagement, increase social sharing, and make your brand the talk of the season!

Enchanted Garden Event Theme

Nature meets elegance in this timeless autumn favourite. Think golden foliage, mossy textures, wooden accents, and candle-lit ambiance. It’s a popular theme for both corporate events and brand activations, especially when you want a warm, organic vibe that doesn’t feel overly branded.

Why An Enchanted Garden Theme For Your Next Event:

• Evokes a cosy, welcoming atmosphere—perfect for brand storytelling.
• Easy to incorporate sustainable elements (a plus for eco-conscious audiences).
• Works beautifully for both day and night events.

Pro Tip:

Use a bespoke decor installation like a moss-covered bar or a floral tunnel entrance for that wow-factor entrance moment.

Night Under the Stars: NYC Edition

This one’s for the dreamers, the cosmopolitans, and the cool-as-ice brands. Night Under the Stars recreates the Manhattan skyline with a rooftop vibe, glittering city lights, jazz-infused soundscapes, and all that NYC drama.

Roaring 1920s Theme
