Testimonials

Have used Harmer Services on several occasions now and always receive a really professional service. Billy has corrected our boiler that has been problematic for sometime that others had failed to do. Fully recommend.

Really professional and friendly, gave good advice and came on time during our water leak emergency!

I've used Harmer Services before and will continue to use them. Very polite, punctual and professional whilst doing a good job. Highly recommended 😊

Taps needed replacing. I called Harmer in the late morning and by early afternoon their engineer was round. The job was completed quickly and to a high standard. Very happy.

Joe, Bill and Gui have been to our property to resolve numerous faults from a previous plumber. Throughout, they have been well organised, punctual and courteous. Stayed after hours to ensure the job is completed, listened to the brief and delivered exactly what was required. We only wish we had met them at the beginning of our refurbishment, rather then at the end. Thank you guys! Highly recommended.
