 Trustindex verifies that the original source of the review is Google. Incredible service from start to finish. Were able to think on their feet and solve problems with my storage heater install in real time - going above and beyond to get the job done, clean up after and making sure I was happy every step of the way.

Could not recommend any more highly.
