I recently enquired with Liam Dunne & Sons about how long it would take to have a solar hot water system installed and how much they charge. within 1 hour of me calling they came around priced the job and I had it installed by the weekend. I was very impressed with the level of professionalism they showed and how fast they got the job done with minimal fuss. I will be referring my friends who are thinking about installing solar hot water systems to this business based on price, efficiency and professionalism.
