About us

About us

Over the last 22 years Fir Tree Technology has evolved from an installer of mobile phone hands free kit and parking sensors into a trusted and reliable partner for supply of commercial vehicle safety systems, driver welfare equipment.

It’s not what we do, it’s how and why we do it.

With Fir Tree the story starts with you, our customer – the commercial vehicle owner. You’re our why.

Welcome to Fir Tree Technology

In the beginning…

July 2001 may well be remembered for the disqualification of Lance Armstrong from the 88th Tour de France, the premiere of Jurassic Park III, the London Stock Exchange going public and, of course, the birth of Fir Tree Technology Ltd!

To the sound track of Craig David’s ‘Born to Do It’ our Managing Director David Imrie finally decided to turn his passion for technology beyond a hobby into a business venture. 

Over the last 17 years Fir Tree Technology has evolved from an installer of mobile phone hands-free kits and parking sensors into a trusted and reliable partner for supply of commercial vehicle safety systems and driver welfare equipment.

The Fir Tree difference

It’s not what we do, it’s how and why we do it

With Fir Tree the story starts with you, our customer – the commercial vehicle owner. You’re our why.

Your need for a hassle free installation of equipment to make your vehicles safe and compliant is achieved through use of the best quality equipment on the market, unique offsite pre-installation processes and a talented team who really do G.A.S.

The end result – a commercial vehicle fitted with the most appropriate vehicle safety technology to meet your individual requirements, accomplished with minimum downtime, offering maximum traceability and a lifetime guarantee on workmanship.

Why work with us?

(You’d be crazy not to!)

We’re are not tied to any manufacturer.

This is a biggie. Fir Tree Technology is totally independent, there is no vested interest in recommending a particular brand of equipment. We can act with true integrity. The benefit to you? An absolute guarantee that you will have the best product/system for your particular installation.

Installation driven methodology.

Everything we do is designed to make the installation of the equipment as quick and hassle free as possible. The Fir Tree pre-preparation process really sets us apart.

By investing the time up front in pre-preparation, our engineers arrive on site with equipment that is ready to install. This allows the maximum number of commercial vehicles to be completed during a visit and minimises your vehicle down time.

Preparing equipment in a clean, controlled, unpressured environment ensures consistency, enables traceability and reduces the risk of error.

Our philosophy is centred on creating “plug and play” solutions.

100% compliance with vehicle manufacturer’s specifications.

At Fir Tree we observe the vehicle manufacturers authorised connection points in the vehicle and their authorised method of connection to ensure that the vehicle’s electrical warranty is not invalidated. You can rest assured that there will be no soldering onto the nearest red wire!

Capability to develop bespoke systems. 

There are times when an off the shelf commercial vehicle safety system just will not satisfy the requirements of the customer.  Rather than “making do” and compromising the final outcome Fir Tree can create a bespoke system to meet your exact specification. This could be achieved by combining kit from a number of different manufacturers or creating a tailor made solution from scratch.

The 3 Rs.

No, we are not talking about reading, writing and arithmetic!  At Fir Tree the 3 Rs relate to reliability, responsiveness and right first time.  That is what you can expect when you deal with our company.

Lifetime warranty on workmanship.

We’re not afraid to put our money where our mouth is!

A unique lifetime warranty is offered on workmanship carried out by Fir Tree Technology Ltd.  For the lifetime of your ownership of a vehicle you will have peace of mind that if anything should go amiss with a system we have installed, because of our actions, we will put it right, free of charge.

Aftersales support.

We’re in it for the long haul, we won’t “cut and run”, and that is a promise. We understand the market in which you operate in – it’s tough, it’s competitive and downtime is costly.

We’ll be there when you need us, 24/7 if necessary.

Fir Tree is a family business.

We’re a small, flexible and committed team with a “can do” attitude, driven by a love for what we do. A far cry from a soulless Plc controlled by boardroom politics and a profit motive. At Fir Tree we really do G.A.S ;o)
