Firefighter Fitness Tests: Chester Treadmill, Bleep Test and the Practical Tests
Quick answer
Most UK fire services test aerobic fitness against a standard of about 42 ml/kg/min, using either the Chester Treadmill Walk Test (12 minutes walking at 6.2 km/h while the gradient rises by 3% every two minutes, up to 15%) or the bleep test to level 8.8. Candidates also complete practical tests — typically a ladder climb, ladder lift, casualty evacuation, enclosed space test, equipment assembly and equipment carry — but weights, distances and time limits vary between services.
Firefighter fitness testing looks similar across the UK, but the details are not identical. Services test the same broad things — aerobic fitness, strength, grip, confidence at height and composure in confined spaces — using a shared set of practical tests, while choosing their own equipment, weights and aerobic test. This guide explains what official sources say about the Chester Treadmill Walk Test, the bleep test and the practical tests, highlights where services differ, and points you to the official training plans. It is general information, not medical or personal training advice.

The aerobic standard: about 42 ml/kg/min
The benchmark most services work to comes from the Firefighter Fitness Best Practice Guide (2016), published through the NFCC, which says firefighters with a cardiorespiratory fitness level below 42.3 ml/kg/min cannot be guaranteed to be safe and effective. The aerobic tests below are ways of checking you meet that level; some services word it as 42 ml O2/kg/min.
Not every service uses exactly that figure or test. Merseyside, for example, describes a running treadmill test to 46 ml O2/kg/min, and the NFCC consulted on updated guidance on managing physical fitness in 2026. Always use the standard in your own invitation.
The Chester Treadmill Walk Test
The Chester Treadmill Walk Test is a graded walking test. London Fire Brigade and the Northern Ireland Fire & Rescue Service both describe it as 12 minutes walking at 6.2 km/h, starting flat for the first two minutes and increasing the gradient by 3% every two minutes, up to 15%. You walk throughout — there is no running.
NIFRS's guide lists the approximate oxygen cost of each two-minute stage, rising to 42 at the final stage, which is why completing the full 12 minutes is linked to the standard. Heart rate and perceived effort may be monitored, and the assessor can stop the test if it is not safe to continue.
Several services use it at selection (LFB on the first of its two fitness days, and West Yorkshire among its physical tests), while others offer a choice: Essex and Lancashire let candidates choose between the bleep test and the Chester Treadmill test.

The bleep test: level 8.8
The multi-stage fitness test, or bleep test, has you run 20 m shuttles in time with bleeps that get closer together as the levels rise. The usual firefighter standard is level 8.8 — the eighth shuttle of level 8. The Scottish Fire and Rescue Service's fitness guide says reaching level 8 shuttle 8 meets its recruitment standard of 42.3 ml/kg/min, and Devon & Somerset, Greater Manchester, Essex, Lancashire, Avon and Surrey all quote 8.8.
There are small variations: South Yorkshire's 2026 candidate pack gives a minimum of 8.7, and some services re-test later — South Yorkshire repeats the bleep test before candidates start, and Essex includes a fitness validation at its assessment centre. SFRS suggests level 8.8 is roughly equivalent to running 1 km in 4 minutes or 5 km in 23 minutes.
The practical tests
The NFCC's on-call recruitment guidance lists the job-related tests as an aerobic test, ladder climb, casualty evacuation, ladder lift and lower, breathing apparatus crawl (enclosed space), equipment assembly and equipment carry, and says the tests vary according to service. The descriptions below show what individual services publish, so you can see the range.
- ✓Ladder climb — climb a 13.5 m ladder, typically to around two-thirds of its height, then lock in or work at height (for example identifying a symbol). LFB, West Midlands and NIFRS use a leg lock; Devon & Somerset and SFRS describe a harness.
- ✓Ladder lift — lift a bar on a simulator to a set height. LFB describes 30 kg to 190 cm and Devon & Somerset around 30 kg to 1.9 m; Hampshire & Isle of Wight describes 15 kg overhead; West Midlands uses a 30 kg grip hold for 40 seconds instead.
- ✓Casualty evacuation — drag a 55 kg dummy, usually walking backwards over about 30 m. West Midlands gives a 40-second limit; Essex describes a 55 kg drag over 30 m.
- ✓Enclosed space — move through a crawl-way or cage wearing a breathing apparatus facemask, often with vision obscured for part of the route, to show you can stay calm and follow instructions.
- ✓Equipment assembly — assemble and dismantle a piece of equipment by following instructions; LFB mentions a portable pump and West Midlands a 5 minute 8 second limit.
- ✓Equipment carry — carry hoses, suction hose and a weighted barbell around a course. LFB, West Midlands and Devon & Somerset all give 5 minutes 47 seconds, but the equipment weights differ (barbells of about 25–33 kg).
Other tests some services add
Some services go beyond the standard set. Merseyside and Devon & Somerset include swim tests (Merseyside describes a 50 m front crawl in open water wearing PPE). Avon adds a lat pull-down and a 30 kg shoulder press, Merseyside a shoulder press, and several services include a ladder extension, ladder carry or hose-running test. South Yorkshire combines equipment carry, casualty evacuation in breathing apparatus and hose carry into a timed Functional Fireground Test.
Order and timing vary too. LFB runs the treadmill on one day and the practical tests on another; other services test everything on one day, and some make you pass the aerobic test before attempting the rest. Greater Manchester says its physical tests must be passed on the first attempt.
How to prepare
Start with your own service's information and, where available, its official training plan: the Scottish Fire and Rescue Service and NIFRS publish 12-week programmes, Cheshire publishes 8-week home and gym plans, and Devon & Somerset an eight-week schedule. The NFCC's message to applicants is that a minimum fitness level is required but can be improved, and shouldn't be a barrier to applying.
In general terms, build aerobic fitness gradually and practise the specific test you will sit — brisk incline walking for the Chester test, 20 m shuttles for the bleep test. Add full-body strength, carrying and grip work for the practical tests, and get used to heights and confined spaces where you can do so safely, such as at a service's taster or practice session. If you have a health condition, an injury, or are new to exercise, speak to your GP or a qualified professional before starting a new programme.
- ✓Check which aerobic test and standard your service uses
- ✓Follow an official plan where your service or another service publishes one
- ✓Practise the test itself periodically to track progress
- ✓Train grip and carrying, not just running
- ✓Rest before test day and follow every instruction on the day
Frequently asked questions
What is the Chester Treadmill Walk Test for firefighters?
It is a 12-minute graded walking test. London Fire Brigade and NIFRS describe walking at 6.2 km/h with the gradient starting at 0% and increasing by 3% every two minutes up to 15%, to show an aerobic fitness of about 42 ml O2/kg/min.
What bleep test level do you need to be a firefighter?
Most services that use the bleep test quote level 8.8 — the eighth shuttle of level 8. The Scottish Fire and Rescue Service links that level to its 42.3 ml/kg/min standard. A few services vary slightly (South Yorkshire's 2026 pack gives 8.7), so check your invitation.
What does 42.3 ml/kg/min mean?
It is a measure of aerobic fitness (VO2): millilitres of oxygen used per kilogram of body weight per minute. The Firefighter Fitness Best Practice Guide sets 42.3 ml/kg/min as the level below which firefighters cannot be guaranteed to be safe and effective.
What are the firefighter practical tests?
Typically a ladder climb, ladder lift, casualty evacuation (usually a 55 kg dummy), enclosed space test, equipment assembly and equipment carry. The NFCC notes that the tests vary according to service, and weights, distances and time limits differ.
Can I choose between the bleep test and the Chester Treadmill test?
Some services let you choose — Essex and Lancashire both describe offering either — while others specify one. Check your service's recruitment pages or invitation.
Are the fitness tests the same at every fire service?
The types of test are broadly shared, but the details are not. Ladder lift weights, barbell weights in the equipment carry, time limits and extra tests such as swimming or shoulder press vary between services.
