Exploring London Through the Eyes of a Spy: A Review of the Slow Horses TV Series Guided Tour

Imagine wandering the unassuming streets of London, not as a typical tourist but as a secret agent on a mission, peering into the gritty, less-glamorous corners of the city. That’s precisely what this Slow Horses TV Series Guided Tour offers. For just under $30, you get a two-hour journey that brings to life the world of MI5’s flawed operatives, centered around the fictional Slough House. The tour is designed for fans of the series, but the real charm lies in its ability to reveal London’s lesser-known, atmospheric spots—a side of the city often overlooked by conventional sightseeing.
What I love most about this experience is how well it integrates the fictional universe with real London locations, especially the exterior of Slough House, which looks unremarkable but is loaded with symbolism. The guide, Suzanne, has been praised for her depth of knowledge and her ability to connect each site directly to the books and TV series, making the stories feel vivid and immediate. Another feature I appreciate is the chance to explore London’s hidden alleyways and unglamorous streets—these atmospheric corners make the series come alive, offering a fresh perspective on a city that’s often seen through the lens of tourist landmarks.
One consideration is that this tour emphasizes the less-glamorous, gritty parts of London, which might not appeal to those seeking iconic sights like Big Ben or Buckingham Palace. If you’re expecting a traditional London sightseeing experience, this might feel a bit obscure. Also, because the tour focuses on the exterior of key locations, you won’t get inside buildings or see major attractions, which could be a downside if your itinerary is tight for time or you prefer more comprehensive sightseeing.

The Itinerary: Walking in the Shadows of London’s Spy World

The tour begins at Old Street Station, outside Greggs Bakers, which is a convenient, central starting point. This location sets the tone—everyday London, but with a twist. From here, the guide, Suzanne, takes you on a walk through the neighborhoods that inspired the series, emphasizing the less-glamorous aspects of the city. She expertly links every stop to the narrative, making even the most mundane streets feel crucial to the spy drama.
The exterior of Slough House is the tour’s centerpiece. Although it appears as an unremarkable, weathered building, it symbolizes the fall from grace for MI5 agents—never glamorous, often bleak. Walking past this building, I could feel the bleak atmosphere that defines the series. Suzanne explained how the show’s creators used this location to embody the series’ tone—dull yet full of secrets.
Following this, you’ll explore London’s underside, discovering how the city’s less vibrant spots are actually vital to the storytelling. This includes alleyways and nondescript streets in the North West corner of the City of London, which serve as perfect backdrops for clandestine conversations and covert operations. Walking through these streets, it becomes clear how the series captures the gritty, tense atmosphere that contrasts sharply with London’s more famous sights.
Throughout, Suzanne shares fascinating insights, making connections between real-life locations and their fictional counterparts. The reviews consistently praise the deep knowledge and storytelling skills of the guides, with Dave noting, “Suzanne was extremely knowledgeable and strongly linked every site to the books and TV show.” For fans, this adds a rich layer of understanding and brings scenes to life in a way that watching alone cannot.
The tour wraps up back at the starting point, leaving you with a new appreciation for London’s hidden corners and the fictional world that has been brought to life there. Because the entire experience is outdoors and walking-focused, it’s advisable to wear comfortable shoes and clothes suitable for unpredictable weather.
Price and Practicalities

At $28.29 per person, this tour offers a cost-effective way to engage with London’s lesser-known side while indulging in a beloved series. Compared to most major attractions, it’s quite affordable, especially considering the expertise of the guide and the unique focus on the TV series. Keep in mind that the tour lasts about two hours, so it’s suitable for those looking for a short, engaging activity rather than a full-day commitment.
The tour is exclusively outdoors and walking-based, which is worth considering if you have mobility restrictions—unfortunately, it’s not suitable for wheelchair users. The meeting point outside Old Street Station is easy to find, and the activity ends where it begins, making logistics straightforward.
Who Would Love This Tour?

This experience is best suited for fans of the “Slow Horses” series, but it also appeals to those interested in London’s less-glamorous, atmospheric streets. If you appreciate storytelling that ties fiction to real locations, you’ll find this tour rewarding. It’s also a good choice for travelers who want a short, inexpensive activity that offers a different perspective on the city—away from the crowded landmarks.
Because the focus is on outdoor exploration and storytelling rather than inside visits, it suits those who enjoy walking and prefer a more authentic, less commercial experience. It’s perfect for adults and older teens who are comfortable on foot and interested in spy stories or London’s hidden side.
Final Thoughts: Is It Worth It?
