Review by Ian Maitland

Ian Maitland - Image 1 "I approached Gasflow & Plumbing Ltd to provide me with a cost to replace my historic Vokera boiler with a new 850 Vaillant spec type. From initial contact, ongoing communications, promptness on quotations and actual appointment dates for install the service was second to none. Let alone very competitive prices to what I was being quoted elsewhere. My old boiler had old service pipes for gas and water completely opposite to what current modern boilers have, the engineer (Daryl) was impressively knowledgeable on what was required, he seemed to progress the install and relevant changes with ease and no hiccups. I am very happy with my boiler and service experienced, would strongly recommend them to others!!"

"I had an excellent experience with Daryl, who fitted my gas hob. From start to finish, he was professional, punctual, and extremely knowledgeable. He carried out the installation safely and efficiently, making sure everything was working perfectly before leaving. Daryl took the time to explain how to use the hob and answered all my questions, which I really appreciated. His attention to detail and commitment to high standards really stood out. I would highly recommend Daryl to anyone looking for a reliable and skilled gas engineer. Five-star service all the way!"
