Lambert - DT1

The surveyor was excellent, he explained everything in detail and while being positive was not over pushy.  He examined my property in detail and advised the various options available and at the end he advised which option he thought was best for me.  He was brilliant.  His after care was second to none.

On the install day an electrician and two fixing staff arrived and again, excellent attitude, very professional and worked very hard, explaining everything as they installed it, I had complete confidence in them.

The employees I met are a credit to Warm Space.  I am prepared to recommend them to anyone.

Dutton - BS15

I was well informed about the products and procedure and the surveyor answered all my questions on the day. There were a few hiccups during the install but this has now all been resolved to my satisfaction . I would happily recommend Warm-Space to family and friends.

Perhaps you will pass on my compliments to all the staff involved in the installation for their skills, timing and pleasant manner when carrying out the work. The ladies who answered the telephone should also be complimented on their helpfulness and manner.
