How We Became Spa No.1 in London: The One Spa London Partnership Story

At One Spa London, our goal has always been simple: look after every client like they’re the most important person in the building. That means listening, tailoring every treatment, and constantly improving the experience, from the moment you discover us online, to the moment you leave feeling lighter, calmer, and genuinely cared for.

But becoming Spa No.1 in London isn’t a solo achievement. It’s the result of collective work a powerful collaboration between experts who share the same standards for quality, professionalism, and client experience.

Below is how our key partners helped bring One Spa London to the top.

1) Tailor SEO: The engine behind our visibility & growth

First and foremost: Tailor SEO our SEO and marketing agency.

In a city as competitive as London, even the best spa can stay hidden without the right digital strategy. Tailor SEO helped us build a strong online presence with data-driven SEO and marketing, focusing on real results: visibility, bookings, and long-term growth. Their work includes in-depth SEO audits, tailored organic SEO strategies, and hyper-local SEO that helps businesses show up when clients search “near me” and on Google Maps. (Tailor SEO)

Because of that partnership, more of the right people found us: clients looking for couples massages near Tower Bridge, relaxing spa days, and high-quality, professional treatments not just “any massage,” but the right experience. (OneSpaLondon)

2) The Circle Gym & Spa: A premium location that elevates the whole experience

Our spa is located inside The Circle Gym & Spa, in Queen Elizabeth Street, SE1 (near Tower Bridge / London Bridge area) and that location is a huge part of why clients love visiting us. (Treatwell)

The Circle gives One Spa London a setting that feels exclusive and complete: it’s not just a treatment room it’s a full wellness destination. On Treatwell, guests can see that we’re situated within The Circle Gym & Spa, and that spa facilities like the pool, sauna, steam room and jacuzzi can be added creating an experience that goes beyond a single treatment. (Treatwell)

This environment supports what we’re all about: real recovery, real relaxation, real results.

3) SamTanOsteo: Rehabilitation expertise that supports deeper results

Wellness isn’t only about relaxing it’s also about moving better, feeling better, and recovering properly. That’s why our partnership with SamTanOsteo matters so much.

Sam Tan is an osteopath and musculoskeletal specialist offering personalised expert rehabilitation in London SE1, with an approach that’s individualised, evidence-based, and focused on long-term outcomes. (samtanosteo.com)

For clients dealing with persistent tension, postural issues, training stress, or post-injury recovery, this connection adds another layer of trust: One Spa London is not “just” spa luxury we are connected to professionals who understand the body deeply.

4) Treatwell: Booking made simple, trusted, and review-driven

Finally, a huge part of becoming London’s top choice is making the experience easy and transparent and that’s where Treatwell plays a major role.
