“We could not be happier with our service from Goliath. Their quote was the most competitive and Tom's attention to detail in the quoting process made sure we understood all our options and all the pricing.

Ben and the team who did the installation were punctual, friendly, tidy and did an excellent job. It was also great that they did all the communication with our energy retailer so we didn't have any of that bother.

After the installation Tom gave us a call and explained everything about using our new system and made sure we knew to call him if we have any further questions. We highly recommend Goliath!”
