“Honestly where to start this chapter. It all started with securing quotes from multiple companies for our loft conversion project at my home in Southend-on-Sea. In the end we spoke to 5+ companies who all gave a similar price. So how do you make your choice? I based it on their portfolio and customer reviews, and Atkins are the leaders in that aspect by a large margin.”
