We have used JDNA for boiler service for yearly service twice. We have been experiencing a crazy noise from the boiler when we opened hot water taps last year. We arranged an appointment for JDNA to have a look (responded quickly and gave more slots to choose from). They came down and had a look and showed the parts with build-up and cleaned it. We also had to change a part due to normal wear. The job was completed in one appointment. I have also carried out the yearly maintenance this year and am happy with it. I would choose them in the future again.

I'm grateful for the outstanding service today! The work quality was exceptional, and the team was friendly and professional. Highly recommend and will definitely use again. Thank you!

These guys are amazing at their job. I've used JDNA LTD several times for different reasons, and I'm never let down by them. They respond quickly, are always on time, and maintain a high level of professionalism. Their expertise leaves you with peace of mind, knowing the job is done right. Cheers again for fixing the problems, offering excellent advice, and ensuring there were no further issues! Highly recommend their services for anyone in need of reliable and efficient assistance.

Simply the best. If you're looking for cheap don't waste their time. They provided an excellent, honest service at a fair price. My single regret is that I didn't find them when I started to refurbish and update. Meticulous to the n'th degree, ensuring drying times etc were adhered, every blemish sorted to their high standards.

Excellent job. Customer Service Quality Value We had a new boiler Baxi fitted by JDNA LTD . Very professional service, very tidy - at the end . Explained very well how to use the new boiler. Thanks for the great and fast work. Their work ethic is outstanding I would definitely recommend them to anyone who requires a professional project.
