How to Watch Slow Horses on Firestick (Every Option in 2026)
Complete guide to watching Slow Horses on Firestick. All 5 seasons on Apple TV+, pricing compared, free trial options, 4K Dolby Vision quality, and how to stream from anywhere with a VPN. Season 6 confirmed for Fall 2026.
I’ve been watching Slow Horses since Season 1 dropped in 2022, and I just rewatched all five seasons on my Firestick 4K Max — 30 episodes of Gary Oldman being the most brilliantly disgusting spy boss on television. With the show scoring near-perfect ratings on Rotten Tomatoes and Season 6 confirmed for Fall 2026, figuring out the best way to watch Slow Horses on Firestick matters more than ever. The short answer is Apple TV+, but there are a few ways to get there — and some of them won’t cost you anything.
Apple TV+ is the exclusive home for all 5 seasons of Slow Horses on Firestick. It costs $12.99/month, and new subscribers get a 7-day free trial — enough to binge-watch a couple of seasons. You can also subscribe to Apple TV+ as a Prime Video Channel if you prefer watching through Amazon’s interface. The Apple TV app streams Slow Horses in 4K Dolby Vision with Dolby Atmos on a Firestick 4K or 4K Max. Need access from abroad? Surfshark works reliably with Apple TV+.
What I Tested For
- Streaming quality — 4K Ultra HD with Dolby Vision and Dolby Atmos on Firestick 4K Max
- Audio quality — Dolby Atmos spatial audio across all five seasons
- App stability — Apple TV app performance across 30 episodes with no crashes
- Subtitle and closed caption options — English, multiple languages, SDH captions
- Cost per season — Which method gives the best value for all 30 episodes
Where to Watch Slow Horses
Slow Horses is an Apple Original — which means Apple TV+ is the exclusive streaming home. All 30 episodes across five seasons are available right now. There’s no ad-supported tier on Apple TV+ — every subscriber gets the same experience, including 4K Dolby Vision and Dolby Atmos.
You can also subscribe to Apple TV+ as a Prime Video Channel, which lets you watch through Amazon’s interface instead. And if you’d rather own the episodes outright, you can buy individual seasons on Prime Video for about $14.99 each — but five seasons at that price runs you $75+. A couple months of Apple TV+ gives you everything for a fraction of that.
| Service | Price | Seasons | Quality | Ads | Free Trial |
|---|---|---|---|---|---|
| 🏆 Apple TV+ | $12.99/mo | Seasons 1–5 | 4K Dolby Vision | No | 7-day trial |
| Best Value Apple TV+ (Annual) | $99.99/yr (~$8.33/mo) | Seasons 1–5 | 4K Dolby Vision | No | 7-day trial |
| Apple TV+ via Prime Video | $12.99/mo + Prime | Seasons 1–5 | 4K Dolby Vision | No | 7-day trial |
| Best Bundle Apple One Bundle | From $19.95/mo | Seasons 1–5 | 4K Dolby Vision | No | 1-month trial |
| Apple Music Student Plan | $5.99/mo | Seasons 1–5 | 4K Dolby Vision | No | No |
| Prime Video (Purchase) | ~$14.99/season | Seasons 1–5 | HD | No | N/A |
| Prime Video (Per Episode) | ~$2.99/episode | Seasons 1–5 | HD | No | N/A |
Bottom line: Apple TV+ is the only way to stream all 5 seasons of Slow Horses. The annual plan at $99.99/year saves you about $56 compared to monthly billing. Students on the Apple Music Student Plan get Apple TV+ included for just $5.99/month — the cheapest option by far.

My testing notes: I streamed all 30 episodes on my Firestick 4K Max across about a week. The Apple TV app was flawless — zero crashes, instant loading, smooth playback throughout. Picture quality in 4K Dolby Vision is outstanding. The dark, moody London cinematography really benefits from HDR — Slough House looks appropriately grimy, and the outdoor surveillance scenes pop with detail. Dolby Atmos came through perfectly on my soundbar, especially during the tenser action sequences. The Apple TV app on Firestick is one of the better-designed streaming apps I’ve used — episode descriptions, season navigation, and “up next” all work exactly how you’d expect.

Season-by-Season Guide
Here’s your roadmap through one of the best spy thrillers on television — each season adapts a different novel from Mick Herron’s Slough House series:
| Season | Episodes | Based On | What to Expect |
|---|---|---|---|
| Season 1 | 6 episodes | Slow Horses | MI5 rejects at Slough House stumble into a kidnapping plot. Gary Oldman’s Jackson Lamb immediately establishes himself as the most repulsive — and brilliant — boss on TV. 95% on Rotten Tomatoes |
| Season 2 | 6 episodes | Dead Lions | A former Cold War spy turns up dead. The plot thickens with Russian sleeper agents. Even better than Season 1. 100% on Rotten Tomatoes |
| Season 3 | 6 episodes | Real Tigers | One of the Slow Horses is kidnapped, and the team has to navigate MI5 politics to save them. The stakes get personal. 98% on Rotten Tomatoes |
| Season 4 | 6 episodes | Spook Street | A terrorist attack hits close to home, and Lamb’s past comes back to haunt him. The most emotionally gut-punching season. 100% on Rotten Tomatoes |
| Season 5 | 6 episodes | London Rules | A series of seemingly random attacks across London forces the team into their most complex investigation yet. 98% on Rotten Tomatoes |
| Season 6 | 6 episodes (expected) | Joe Country & Slough House | Fall 2026 (expected). The first season to adapt two novels. Filming has wrapped. Gary Oldman teased the return at an Apple event |
| Season 7 | TBD | Bad Actors | Renewed — no date yet. Announced July 2025 |
Total watch time for all 5 seasons: About 18 hours across 30 episodes at roughly 35–42 minutes each. You could binge the entire series in a weekend if you’re committed — and trust me, once Jackson Lamb gets under your skin, you will be.
Free and Cheaper Options
Free Ways to Watch
| Method | Details | What You Get |

Budget Strategies
- Apple TV+ 7-Day Free Trial — If you’ve never subscribed to Apple TV+, the 7-day free trial gives you full access. At six 40-minute episodes per season, you could realistically binge all 30 episodes in 7 days. It’s tight — about 4–5 episodes per day — but doable.
- Apple Music Student Plan ($5.99/mo) — If you have a valid student email, this is the cheapest ongoing option. You get Apple Music AND Apple TV+ for less than half the price of Apple TV+ alone.
- Apple TV+ Annual Plan ($99.99/year) — Works out to about $8.33/month. Saves $56 versus paying monthly over a year.
- Apple One Bundle (from $19.95/mo) — Gets you Apple TV+, Apple Music, iCloud+, and more. Worth it if you use multiple Apple services.
- Buy a New Apple Device — Any new iPhone, iPad, Mac, or Apple TV comes with 3 months of Apple TV+ free. If you’re already planning to buy one, this is the best deal.
Digital Purchase (Own Forever)
If you’d rather own the show outright:
- Amazon Prime Video — Buy individual episodes (
$2.99) or full seasons ($14.99)
At $14.99 per season across five seasons, you’d spend about $75. Two months of Apple TV+ at $12.99/month gives you the entire series — plus everything else on Apple TV+ — for $26.
Streaming Quality Breakdown
Slow Horses streams in 4K Dolby Vision with Dolby Atmos on Apple TV+ — every season, every episode. Apple doesn’t gate premium quality behind a more expensive plan like some competitors. If you’re paying for Apple TV+, you’re getting the best available picture and sound.

Watch Slow Horses From Anywhere
Apple TV+ is available in 100+ countries, and Slow Horses is generally accessible wherever Apple TV+ operates. But if you’re traveling or live in a region where the show isn’t in the catalog, a VPN connected to the US or UK solves the problem instantly.
