Below are a few of the many positive testimonials we have received from clients that we have worked with:

I have always found that whenever I have required extra labour requirements, the team consisting of Colin, John & Terry have always responded quickly and very positive to our business needs and requirements. They have always sent good quality people to the projects at all times. I can highly recommend Sapphire Services to support and resourse manpower for Oil, Gas Petrochemical, & Power Industry and provide you with the right people for your business.

Well done and again thanks for your help

Imagine the sun is out this Saturday afternoon the barbecue has been lit and your friends are on their way round and it's time for another beer what more could you ask for, then the phone rings it's Gary Kaefer delivery manager I need you to work tonight we have a breakdown I need scaffolders for a 12 hour nightshift starting at 20:00 hours. As you can imagine the replies I get back again and again after trying and trying but Gary the sun is out and its Saturday, so what do I do to find decent men tonight,

I'm now looking at my options,

Another option is to utilise agency workers to fulfil and meet our clients expectations, we need to mobilise men: I phoned Sapphire Agency Services spoke to Colin Graham, He understands my business he understands the quality and the commitment of the guys that I need at short notice bear in mind now is 14:00 hours. I made the call to Colin he said to me Gary give me an hour I will get you local men, within the hour Colin had local guys with all the right certificates knowledge to the job that we needed to undertake and turned up on time ready to go, what with working with such a reactive call off basis if it wasn't for Sapphire and especially Colin Graham we would have certainly been in trouble to support this requirement and would like to put a special thanks to Sapphire for the work that they undertook for us at this challenging time,

Absolutely First class service's supplied by Sapphire a true credit to our and any business,

A Massive thank you,
