Client Testimonials


I just wanted to take a moment to feedback how great your engineer was yesterday. Its difficult for me to be working from home with meetings, calls and interruptions, but your engineer was brilliant, professional and so helpful working around the open reach engineer, and constant deliveries whilst he was here.

It’s hugely appreciated and you should be very proud of how your engineers are conducting themselves.


I will say the we are happy with the install and the product along with the fact that the engineer was professional and helpful which is hard to find these days.

I was very happy with the service I received from your engineer. Please convey my thanks to him.
Your engineer Craig came to our new house yesterday to service the Alarm and I just wanted to say how impressed I was with his knowledge, friendly attitude and customer service skills. When moving into a new home there is so much to do and so many utilities and people to deal with, having Craig here to service our Alarm system brightened my day. Thank you so much, I will certainly use your company again.

Just had one of your Engineers visit to service my alarm and as always on time ! I asked for a first call at 8.30 and he arrived a few minutes early, great stuff the Engineer was efficient, very pleasant and courteous so a big thank you to him. Have to say, you deliver great service something a lot of other companies don’t get right
For many years in my capacity as Technical Director and Managing Director for a number of major house builders I have used Rainbow to install our Electrical and Alarm systems and they have consistently maintained a high level of service and quality throughout.

When we set up Heyford Group in 2003 it was therefore a natural choice for us to maintain a good relationship with Ian, Trevor and their team to carry out installations on our various projects. They are one of our most trusted and reliable subcontractors who have demonstrated their capabilities to adapt to the variety of schemes carried out by both our Homes and Contracting organisations.

I would like to say that we were very happy your engineer who popped over to see us again today to assist with the problem we had with our sim card.

I rang your offices today after your Engineer Dave called to carry our the annual service to my Alarm system. I wanted to record my thoughts in an email as far too often people only find time to complain, but I believe when good customer service is received it should be highlighted too. Dave arrived and discovered that a new bell box, battery and smoke detector required attention. He carried out the work speedily and efficiently within the time allocated, he was professional, helpful and polite, a credit to your company. What a great attitude he displayed, thanks to you all for this level of service, I hope he is recognised for going the extra mile.
