 Trustindex verifies that the original source of the review is Google. Sharif bhai did a very good job in my property. He fitted the shower properly and fixed the leak issue. He checked everything carefully and made sure there was no more leaking after the work finished.
He was polite, professional, and helpful. The work was neat and clean, and the shower is now working very well.
I am happy with his service and I would recommend Sharif bhai to others for plumbing work.

 Trustindex verifies that the original source of the review is Google. I recently had my boiler serviced by Heatgap( 99 Byron Road,Luton) and I couldn’t be happier with the experience. The Technician arrived on time, was professional, and explained everything clearly. The service was thorough, and they made sure the boiler was running safely and efficiently before leaving.
What really stood out was their friendly attitude and attention to detail. They took the time to answer my questions and gave helpful advice on maintaining the boiler.
Overall, excellent service from start to finish. I would definitely recommend Heatgap to anyone looking for reliable and professional boiler servicing.
