Reviews

4.0

Jose & Blackler Limited is described as giving excellent, prompt service, with several reviewers reporting that engineers arrived on time and that final costs matched the quote. Reviewers also mention helpful office staff and friendly, knowledgeable engineers, including work on air source and Grant heat pumps and underfloor heating, with one reviewer saying a plumber explained the system patiently. One reviewer said invoices are not very specific but that this was easily addressed. Criticism includes one reviewer who called the firm overpriced and said a challenge to an invoice led to a threatening letter, and another who said a boiler installation was left unfinished for two weeks and had to be completed by someone else.

Excellent service. From first contact we very quickly realised this was an extremely professional company. We were quoted the same day and they scheduled to resolve our problem at short notice. Arrived on time with the required part. The plumber was the most knowledgeable chap we had come across regarding our air source heating system. In addition, he was friendly as was everyone in the office. Final costs were exactly as expected. I would highly recommend Jose and Blackler and will definitely be using them again.

Jose and Blackler provided an excellent service. Office staff were very helpful. The engineer was thorough and patient in checking and explaining the underfloor heating system, which we had no previous experience of. We would be happy to recommend them to others.

Great company that has good engineers along with supportive office staff. Invoices are not very specific and could be improved but this was easily addressed.
