UK Safety Management are very pro-active and make sure they contact you to book in. We have found the last few times we have used them that at short notice they have to change their dates, which we understand can happen, but can be disruptive when you are making sure the equipment (which can be out on jobs) is in to be looked at. We have had the same electrician/engineer a few times now, which is nice because he is very friendly, professional and considerate, plus he knows our site a little better so we don't have to be too involved. I am not sure on pricing how they compare to others, but they haven't done anything wrong to make us look elsewhere. They are very quality conscious and ensure their staff have been good on site, which is a bonus.
