Refresher for Tree Climbing and Aerial Rescue

(formerly CS38)

Tree climbing and aerial rescue refresher

Things you must consider when it comes to tree climbing refreshers, is who is asking you for the evidence of a refresher?

  • Is it for your peace of mind?
  • Requirements of your insurance company?
  • A contract that you have to fulfil?

Before booking be sure that this refresher course will fulfil your requirements. 

If you have contracts with specific companies they may insist on awarding organisations refresher certificates.

With City and Guilds, your option is to do the assessment again and be reissued a certificate as long as you pass again. Please ask for assessment prices if this is what you require.

Lowe Maintenance Certificate of Completion

This is the certificate you will gain on successful completion of your tree climbing and aerial rescue refresher course. 

We would advise that you check with your insurance company before booking to ensure they are happy with a certificate of completion, many are, but is it certainly worth checking first!

Companies we already provide refresher courses for are:

  • Jacobs
  • Burnley Borough Council
  • amongst many others 

Our one-day tree climbing refresher training course provides you with any industry updates, along with plenty of time for you to demonstrate your climbing and aerial rescue methods. 

Group sizes are no more than four candidates to one trainer, so nice small group sizes. To allow for plenty of discussion and questions. 

You will have access to the Lowe Maintenance portal on booking where you will find leaflets and updates to look through before attending the practical session.

Carrying out tree climbing activities within industry as a professional is something to take seriously, as such it is important to keep up to date and attend refresher courses. 

Think of it this way, if you have an incident one of the first questions your insurance company or HSE may ask, is,

‘When were you last refreshed?’

It’s not going to sound so good if you say you haven’t had a refresher since you did your original course twenty years ago.

Don’t forget HSE advise a refresher every 5 years and some insurance companies are now insisting on a refresher course every three years. 

Do you know what your insurance company requires?


With all this in mind and you are now faced with having to gain your tree climbing refresher have you been:

  • struggling to find the right fit in terms of a training provider?

There is nothing to stop you using them but courses are normally run using the basic friction devices as not everyone can afford these more expensive pieces of equipment. Having a standard system during the training makes the rescue situations easier to understand, however, if you are going to use lock jacks and spider jacks it is extremely important everyone in your team understands how to use them.

The main knots used throughout the training course with Lowe Maintenance are:

  • Bowline
  • Blake’s hitch
  • Prussic
  • Lark’s foot
  • Stop knot

Personal tree climbing equipment is supposed to comply with the Lifting Operations and Lifting Equipment Regulations 1998. It should be inspected on a 6-monthly basis by an independent person. This period cannot be extended but may be shortened due to the working environment or specific requirements of the site you are working on.

You are advised by HSE to have a refresher every 5 years, this however depends on the company you work for, as some have different regulations for refreshers such as National Trust which is every 3 years.

There are a number of leaflets about this, one is provided by the Bat Conservation Trust ‘How are trees important to bats’. If you look at their website you will be able to download lots of good information. You should arrange a tree survey if you are worried, just to be sure. 

This is not good practice but it is also not that easy to spot an occupied tree.

If you know it to be occupied, then the answer is no as you may disturb the roost and that can be a bit expensive in the form of court actions and possibly your professional reputation.

That is up to you and your confidence levels. If there is a problem, you will have to explain to the insurance company why you were up a tree on a particularly windy day.

Yes, there is no reason why not. The tree may be a bit more slippery and you may have to adapt the climb to the conditions but there is no reason why you can’t.

A double-action karabiner means it has two motions to close the gate and make it secure, these are easily opened and have been known to open due to rubbing on the trees and branches.

This is why they should not be used as part of the life anchor points in the climbing system.

The triple-action has three motions to close the gate. Furthermore, the triple-action is the only karabiner to be used as part of the life anchor point as it is harder to open accidentally.

No, you only need to wear a pair of work trousers and stout work boots with ankle support. You can if you want to or if the weather is a bit cold but there is no chainsaw use so, therefore, no need for cutting pants.

It is advisable that you have another climber on-site in case something goes wrong. It takes time for the emergency services to respond, that second climber can get to you quicker and shorten the time it takes to get proper help. Most noteworthy is that your insurance company will want you too!

The branch size depends on the characteristics of the tree and its condition. The branch must be strong enough to take lateral forces as well as supporting the climber. On the tree climbing course, you shouldn’t suspend yourself from branches less than 4” in diameter.

SRT is Stationary Rope Techniques or Static Rope Techniques, this is a method of accessing and working a tree using mechanical aids to climb. It can make climbing a lot easier but requires a good understanding of rope systems and equipment.

It is advisable for your personal growth to learn more about trees and their characteristics. Especially with the number of pests and diseases that are about these days. We need to improve our biosecurity in general.

The Arboricultural Associations Guide to Climbing Practice has a list of the equipment you need. The number of pieces is down to you and your budget.

Be careful as it is easy to buy too much and buy lots of shiny bling that you may never use. If you attend a course with Lowe Maintenance, you will know what to buy by the end of the course as you’ll have used our kit during the course.

Ropes are like harnesses; the choice is down to personal feel. The average rope is 10mm to 13mm diameter although 12mm to 13mm is more commonly used as they are easier to grip and less chance of hand strain. The smaller diameter ropes are used mainly with mechanical aids and, depending on the item you use, as a friction component. The manufacturer may state a rope diameter, which you should follow for your own safety.

It is a strong recommendation that anyone working with a chainsaw should have some level of first aid training due to the increased potential for an accident.

HSE advise that you practise at least once a month. If you require an aerial rescue refresher give us a call to arrange a suitable date.
