British Naked and Afraid Survivalists: The Complete UK Cast Guide

Last updated: 12 July 2026

Naked and Afraid has tested hundreds of survivalists from around the world, but only four verified contestants from the United Kingdom have appeared in the main programme or its official spin-offs as of July 2026:

• Jamie Frizzell from Scotland
• Sam Mouzer from England
• Steven Kelly from England
• Jennifer “Jenny” Kelly from England

Together, the four British survivalists have made nine aired challenge appearances and recorded approximately 150 days in the field.

Jamie Frizzell has also been announced for Naked and Afraid: Shipwrecked, scheduled to premiere in the United States on 2 August 2026. Because the series had not aired when this guide was updated, its challenge days have not been added to his completed total. Warner Bros. Discovery currently credits Jamie with 55 previous days in the franchise.

This independently researched guide records every verified British contestant, including their episodes, filming locations, confirmed field days, results, later franchise appearances and available post-challenge interviews.

It also distinguishes between officially confirmed statistics, information shown during episodes and figures calculated from publicly available programme records.

Disclosure: This independently researched guide is written by Steven Kelly, also known as Survival Ste, a British TV survivalist, former 29 Commando Regiment soldier, survival instructor, podcast host and founder of South West Survival. Steven and his wife, Jennifer Kelly, are both included, and the same evidence and counting rules are applied to every contestant.

British Naked and Afraid contestant comparison

Official programme listings and established independent reporting identify Jamie, Sam, Steven and Jenny as the four publicly documented UK contestants covered by this guide. No verified contestant from Wales or Northern Ireland was identified during the research for this update.

Jamie Frizzell was the first person from the United Kingdom to appear on Naked and Afraid. Jennifer Kelly is the first publicly documented woman from the UK to appear in the main programme.

At the time of this update, Steven Kelly has the highest confirmed British total with 56 recorded field days across two completed challenges. Jamie Frizzell has 55 recorded days before his upcoming Shipwrecked appearance.

How this guide counts challenges and survival days

The following rules are used throughout this guide:

• Each separate filmed survival challenge is counted as one appearance.
• Actual field days are used instead of the planned challenge length.
• Upcoming appearances are listed but are not added to completed statistics.
• A completed challenge means the contestant reached the required finishing point.
• A voluntary tap means the contestant chose to leave the challenge.
• A medical evacuation means the programme’s medical team ended or supported the end of the contestant’s participation.
• Calculated or estimated totals are clearly identified.
• Season and episode numbering may differ between countries and streaming platforms.
• Official programme listings, established publications and direct contestant accounts are prioritised over fan databases.

Jamie Frizzell

Scotland’s first Naked and Afraid contestant

Jamie “WildMan” Frizzell is a Scottish survivalist, bushcraft instructor, adventurer and former lifeguard from Ayr.

Jamie became the first person from the United Kingdom to appear on Naked and Afraid when he took part in “USA vs. World”, filmed in South Africa.

The episode brought together two teams of international survivalists attempting a 21-day challenge. Discovery+ lists it as Season 13, Episode 4, although season numbering can differ on some platforms.

Jamie later returned for Naked and Afraid XL, Naked and Afraid: Solo and Naked and Afraid: Last One Standing.

He has also been announced as one of 12 returning survivalists taking part in Naked and Afraid: Shipwrecked in the Philippines.

Jamie Frizzell’s challenge record

Entertainment Weekly’s preview of Naked and Afraid: Solo confirmed that Jamie had completed his original 21-day challenge before tapping on Day 2 of XL in the Amazon. Solo then required him to attempt another 21 days completely alone.

Warner Bros. Discovery’s Shipwrecked announcement credits Jamie with 55 days before the new series. His first challenge, XL appearance and Solo challenge account for 44 days, which places his Last One Standing run at 11 days. This is a calculated figure rather than a separately published official statistic.

Jamie was medically evacuated during Last One Standing after becoming seriously unwell in the Australian heat.

Challenge analysis

Jamie has faced more different Naked and Afraid formats than any other British contestant.

His original challenge required cooperation within an international group. Solo removed the support of a partner entirely. Last One Standing added competition, timed skills tests and the need to manage other contestants as well as the environment.

His record also shows how different challenges can expose different weaknesses. He completed two separate 21-day challenges but left XL on Day 2 and was medically evacuated from Last One Standing.

That does not make the earlier completions less valid. It demonstrates that survival results are influenced by the location, physical condition, format and timing of each challenge.

Jamie Frizzell’s later appearances

Jamie’s franchise timeline includes:

• Naked and Afraid in 2021
• Naked and Afraid XL in 2022
• Naked and Afraid: Solo in 2023
• Naked and Afraid: Last One Standing in 2025
• Naked and Afraid: Shipwrecked in 2026

Shipwrecked begins with 12 survivalists being unexpectedly abandoned in open water at night near the Philippines.

The contestants must reach shore, form teams, locate the separate pieces of a challenge map and attempt to rescue themselves from the island on Day 35.

Sam Mouzer

From Quarry Bank to New Mexico and Colombia

Sam Mouzer is an English military veteran, mental health counsellor and survivalist from Quarry Bank in the West Midlands.

His first appearance was Naked and Afraid Season 15, Episode 1, “Welcome to America!”.

Sam was partnered with Austrian survivalist Lilly Jammerbund for a 21-day challenge in New Mexico. They were promoted as the first two international contestants to attempt a standard 21-day Naked and Afraid challenge on United States soil. Both completed the challenge.

Sam later returned for Naked and Afraid XL Season 10, titled “40 Miles in 40 Days”, filmed in the Colombian Badlands.

Sam Mouzer’s challenge record

The XL season required 12 returning survivalists to move through six separate Colombian environments while attempting to cover 40 miles in 40 days.

The contestants faced extreme heat, storms, parasites, ticks, mosquitoes, snakes, caiman and jaguars.

Sam left during Episode 3, “Ticking and Screaming”, after a tick bite and other insect bites caused serious discomfort and swelling. The programme’s official “29 days remain” promotion places this point of the 40-day challenge at approximately Day 11. Because an exact total is not consistently stated in official cast records, this guide lists his XL run as approximately 11 days.

Challenge analysis

Sam’s two challenges demanded different forms of resilience.

New Mexico brought cold nights, rattlesnakes, unfamiliar terrain and the pressure of working closely with a partner from another country. Completing the full 21 days showed that effective communication and morale can be as important as technical skills.

His XL challenge was a reminder that small physical problems can escalate quickly.

Insect bites are easy to dismiss from the safety of home. In the field, repeated bites, swelling, broken skin, poor sleep and the risk of infection can steadily remove a contestant’s ability to function.

Leaving a challenge is not always the result of one dramatic incident. It can be the end of several smaller problems building on top of hunger, exhaustion and exposure.

Sam Mouzer’s later appearances

Following his first challenge, Sam appeared in:

• Naked and Afraid XL Season 10
• Naked and Afraid interviews and cast discussions
• The Bushcraft Show’s 2026 Naked and Afraid panel

No further Naked and Afraid appearance featuring Sam had been publicly announced as of 11 July 2026.

Steven Kelly

From 29 Commando Regiment Royal Artillery to the Colombian jungle

Steven Kelly, also known as Survival Ste, is a British TV survivalist, former British Army soldier who served with 29 Commando Regiment Royal Artillery for 23 years, survival instructor, podcast host and founder of South West Survival.

His wider television credits include E4’s Naked, Alone and Racing to Get Home, BBC One’s Bear Grylls: Wild Reckoning, Insight TV’s No Time To Lose and Castle Rock.

His first franchise appearance was Naked and Afraid Season 17, Episode 5, “Runaway Bride”, which first aired in the United States on 17 March 2024.

Steven was partnered with Meagan “Sunny” Forsythe for a 21-day challenge in the mosquito-infested Colombian tropics. Both contestants completed the challenge.

Steven returned in 2025 for the first season of Naked and Afraid: Apocalypse.

The series placed 12 contestants in abandoned areas of South Africa, including a ghost town, vehicle junkyard, cemetery and mine.

Instead of waiting for a conventional extraction at the end, the remaining contestants had to navigate back towards civilisation.

Steven Kelly’s challenge record

Steven’s confirmed combined total is 56 days across two completed Naked and Afraid challenges.

First-hand challenge analysis

My Colombian challenge was not simply a test of whether I could build a shelter, make fire or find food.

The real battle was managing physical decline across 21 days.

Constant humidity made it difficult to stay dry, protect equipment or recover properly. Food was limited, sleep was broken and basic jobs became harder as my energy dropped.

The important decisions were often about what not to do.

Every movement used calories. Every unsuccessful hunt or unnecessary job could leave us weaker without improving our position. We had to decide which tasks were essential, which could wait and when resting was the best survival decision.

Naked and Afraid: Apocalypse required a different approach.

Instead of remaining in one natural wilderness area, we moved through abandoned man-made locations and scavenged useful materials from damaged vehicles, buildings and other debris.

We had to work out what could be repurposed safely. Materials that looked valuable could also be sharp, unstable or contaminated.

Mobility mattered as much as shelter. Using too much energy early in the challenge could leave us without enough strength for later movements and the final route back towards civilisation.

Completing the 35 days required energy management, practical improvisation and the ability to keep making clear decisions while hungry and physically depleted.

Steven Kelly’s later appearances

Steven’s Naked and Afraid appearances include:

• Naked and Afraid Season 17
• Naked and Afraid: Apocalypse Season 1
• The Bushcraft Show Naked and Afraid panel in 2026

Steven also hosts The Survival Debrief Podcast, featuring interviews with contestants from Naked and Afraid, Alone and other survival programmes.

No further Naked and Afraid challenge featuring Steven had been publicly announced as of 11 July 2026.

Jennifer “Jenny” Kelly

The first publicly documented UK woman on Naked and Afraid

Jennifer “Jenny” Kelly is an English outdoor enthusiast, television survivalist and survival instructor from Plymouth.

She appeared in Naked and Afraid Season 18, Episode 3, “Return of the King”, alongside first-time contestant Allison and returning franchise veteran Steven Lee Hall Jr.

The episode was filmed in the backwoods of Kentucky and first aired in the United States on 16 March 2025. Discovery’s official listing describes the episode as a 21-day challenge involving two first-time contestants and Steven Lee Hall Jr.

Jenny entered the challenge wanting to confront her fear of wildlife and sleeping outdoors without normal protection.

She voluntarily left on Day 7 after repeated anxiety, poor sleep and the physical and psychological strain of the challenge. The Day 7 timeline is shown during the episode.

Jenny is the first publicly documented woman from the United Kingdom to appear in the main Naked and Afraid franchise.

Jennifer Kelly’s challenge record

Challenge analysis

Jenny’s challenge demonstrates an aspect of survival television that is often underestimated: psychological attrition.

A contestant can possess practical outdoor skills and still struggle when fear prevents proper sleep.

Sleep loss affects concentration, emotional control, coordination and decision-making. Once anxiety begins disrupting every night, the contestant starts each new day with less energy and a lower ability to deal with the next problem.

Jenny’s decision to leave was voluntary. It also showed that knowing when a challenge has moved beyond a manageable level is part of personal risk management.

A tap does not erase the courage required to enter the challenge, expose personal fears on television and attempt something most people would never consider.

Jennifer Kelly’s other television work

Before Naked and Afraid, Jenny appeared on the E4 survival programme Naked, Alone and Racing to Get Home.

No later Naked and Afraid appearance featuring Jenny had been publicly announced as of 11 July 2026.
