Very professional, quick and clean repair of our leaking heating interface unit (HIU). And above all, it was cheaper by a half than the ones referred to us by management company. Money well spent!

Very knowledgeable engineer, who also advised me how to put inhibitor into the heating water system to prevent corrosion and malfunction. BEST PRICE: £120 INCL. VAT TO REPLACE TWO HIU PARTS

Very responsive and professional service with a smile.

Add Detail were a pleasure to work with. They came to install a new HIU unit in my flat. They arrived on time and were able to finish the work faster than expected. They were also able to work out a preexisting problem within the pipes that other service providers had failed to fix.

Good service and timing. Friendly HIU technician. Would recommend!

Add Detail always resolve our heating issues with timely and professional manor, I've been using them for the past few years and their professional skill and knowledge is up to a good standard, which helps us save costs and resolve the problem fairly quick.

Very responsive and professional, able to identify the problem very quickly while giving thorough explanations to someone with 0 knowledge in the area. Would recommend and work with them again moving forward!

Brilliant, first class service. Thank you Justin. Highly recommend Add Detail LTD, I will definitely use Add Detail LTD in the future.

Made contact with Add Detail through a recommendation. Found Sigis and Justin to be very prompt and proffessional and handled the issue with my HIU unit with minimum fuss. Also their prices are reasonable. Would highy recommend.
