Plamen has been an absolutely top-class professional throughout. He replaced the blown thermostats in our immersion heater and also went out of his way to find ones that were reasonably priced (several were excessively priced). Here he really went above and beyond, which took him many hours of driving to find and then return and finish the job! He also helped me balance the pressure in our underfloor heating and provided some really helpful advice and tips with other aspects of the heating system, again demonstrating his deep knowledge and expertise. I will 100% be coming back to Topflow if we need any help in the future!! Thank you kindly - another very happy customer :)Posted on Google![]()

Plamen came today at very short notice. I found his details in checkatrade. My kitchen was flooded with water due to blocked kitchen sink. He said he could be at my place after finishing another job and he arrived in less than 1 hour. He wore shoe protectors to avoid leaving any dirt on my floor. He unblocked the drain, gave me some good advice. Very courteous and professional. I will definitely call him again and he also does handyman work.Posted on Google![]()
