CHEMISTRY: THE MIXER PARTY FOR SINGLE OVER 40s
If you’re tired of endless swiping, awkward apps, and events that don’t deliver, Chemistry is for you.
Held at some of London’s finest venues, Chemistry is a vibrant, welcoming singles party created exclusively for people who are serious about meeting someone special – without the pressure.
✨ What to Expect
✅ Up to 100 like-minded singles, carefully balanced by gender
🍸 Stylish Central London venues – perfect for relaxed conversation
🎤 Engaging ice-breaker games hosted by our expert tea
🧠 Smart matching after the event – only mutual likes lead to contact
No awkward intros. No speed dating. Just good conversation, a great atmosphere, and the chance to meet someone who gets you.
❤️ Why It Works
Chemistry is designed for singles in their 40s and 50s who know what they want – and who don’t want to waste time. We take care of the setting and introductions so you can focus on enjoying the evening and making real connections.
Our guests tell us they feel more relaxed, more open, and more themselves – which makes all the difference.
“A brilliant evening – classy venue, fun format, and I actually met someone I clicked with. Highly recommended!” – Sarah, 47
