For over 120 years, we’ve provided confined space rescue services – making us not only one of the most experienced confined space training companies, but also one of the most accredited.

We provide a wide range of City & Guilds approved confined space training courses, all of which are suitable for many industries. Our courses are highly practical – and are taught in state-of-the-art facilities which include conditions that replicate what a person may encounter when working in real confined spaces such as tunnels, pits, sewers or tanks. In these facilities our trainers can simulate what it’s like to enter, exit and work in spaces which are considered a high, medium or low risk confined space. And also, how to escape and if necessary, carry out a rescue in a safe manner.

Which confined space training course should I choose?

Our courses comply with all current regulations and the requirements of the National Occupational Standards. Those who complete assessments successfully can choose to receive City & Guilds 6160 certification where available, or our MRS certificate if preferred which is in alignment with this.

Frequently asked questions

Our confined space courses are accredited and certified by City & Guilds. We work closely with City & Guilds to create the qualifications for confined spaces – including the standards for confined space entry and rescue.

This accreditation means we are subject to annual audits by the awarding body for each accredited course we offer.


We own and maintain all the equipment used by delegates on our courses – and only use the equipment we trust and would use ourselves. Those who attend our confined space training courses will get to use a wide range of equipment – dependent on the course attended, this may include; man riding hoists, escape breathing apparatus and auxiliary ventilation to name just a few.

We also sell the equipment we use as part of training – to find out more, contact us.

According to the regulations, a specified risk can be:

  • Injury caused by fire or explosion
  • Loss of consciousness caused by an increase in body temperature
  • Loss of consciousness or asphyxiation caused by gas, fume, vapour or lack of oxygen
  • Drowning
  • Asphyxiation cased by a free flowing solid or the inability to reach safety due to entrapment by a free flowing solid

It should be noted that the specified risk may not always be there – it may be introduced by the nature of the work, i.e. cutting, welding, spray painting.

According to the Confined Spaces Regulation 1997, a confined space is defined as a ‘space in which, by virtue of its enclosed nature, there arises a reasonably foreseeable specified risk’.
Common confined spaces include:

  • Sewers
  • Tanks
  • Vats
  • Silos
  • Tunnels
  • Wells

A confined space is not necessarily an area you have to ‘squeeze’ into – or a space in which you must crawl around on your hands and knees. Some confined spaces may be harder to identify, as they are not enclosed on all sides or may be very large, like a ship’s hold. If you’re trying to determine if a space is a confined space or not – consider the work to take place in that area, and whether the work increases the risk of serious personal injury from hazardous substances or conditions within the space or nearby.

When work must be carried out in a confined space, a safe system of work which identifies the hazards, the risks and the control measures must be created. The purpose of this is to ensure the work can be controlled and undertaken with an acceptable level of risk.

Furthermore, if you require employees to enter a confined space, you must prepare suitable and sufficient arrangements for their rescue. Very importantly, this is required even if the emergency is not brought about by a specified risk. Your rescue arrangements need to ensure you are protecting the rescuers and, where necessary, include resuscitation equipment.

Working in a confined space will always have an element of risk, but these risks can be controlled to make the risks acceptable. The risks and controls need to be understood by all who work in confined spaces.

If you are unsure and would like a site visit so our confined space experts can assess your spaces and advise on how to ensure the safety of your workforce, get in touch.

If you need support in identifying confined spaces – or understanding what training your employees need to be compliant, we can help. Our consultancy team are specialists and provide a full range of services – which are all compliance guaranteed.

The services we can provide include; confined space surveys and audits, training consultancy, expert accident and incident analysis, managing confined spaces support and emergency rescue and response services.

Working in confined spaces has resulted in fatalities and injuries, across a variety of industries. To try and reduce this, the Confined Space Regulations 1997 were introduced.

There is a requirement under both the Health & Safety at Work Act and the Confined Space Regulations, to ensure people are trained and competent to carry out the planned work activities. The objective of any training is to reduce the risk of injuries and fatalities.

Excellent training, with experienced and friendly instructors. Clear, concise and informative content.

Kyle Friest, FCC Environment

MRS are the best in the business. Relaxed atmosphere, fantastic knowledge . Trainers are confident to deliver and nothing to much trouble. During these difficult times MRS have nailed it, plenty of space no risk of sharing others apparatus plenty to go around. I would not book my team on a course anywhere else. Always a pleasure to go back.

Paul Vardy, Turbine Surface Technologies

I attended a 2 Day course this week with 4 other colleagues. I would just like to compliment the Trainer Ben Denials he is a credit to your company! I have personally been involved in confined spaces for 20 years and attended several courses and Ben seems to have a really calm approach and training style which was perfect for our operatives who stated it made a huge difference to them

Neil Bartlett, Highways Supervisor & Recycling, Swansea Council

MRS have made a conscientious effort to keep all personnel save during the pandemic. The confined space training i attended recently was delivered to a very high standard by knowledgeable and experienced trainers and assessors. Many thanks.

Mick Firth, Firmac Civils Ltd

Having just attended a 3 day "working in confined spaces with rescue and BA course" I must highly recommend the MRS team, especially Elliot our trainer who was excellent, very patient and a superb teacher. I would very much recommend anyone working in any industry that uses confined spaces or breathing apparatus to attend one of MRS courses.
