Guaranteed to the Last Drop!



Our customer service is what sets us apart from other companies because we honestly want you to have the best possible experience you can.

It can be hard work finding a tradesman that will:

A) Return your phone call
B) Turn up on time & complete the job within a time frame
C) Be available for contact if there is anything else you need

Well, we do all three. From your first point of contact with a real person in the office, you will be taken care of from the start to the end of the job, being informed every step of the way so there are no nasty surprises.


    If something untoward happens and workmanship is the issue, we will sort it out at no cost to you.


    Call before 1pm and we will guarantee same day service.


    If you are not happy with ANY part of our service, the first hour is free!

A super professional and prompt service offering everything I need: quick easy confirmation of the job, kept me up to date, turned up on time, friendly and efficient service, easy billing and payment. I am very happy with the work done and the communication from was fantastic: I can't think of how they can do a better job. Highly recommend and will definitely be using this company every single time.



Macmillan Plumbing were a pleasure to deal with from start to finish - from the friendly and helpful receptionist who first answered, to the plumber who showed up exactly when he said he would, let me know exactly what was going on, and stuck to the quote exactly. Part of the work being done was fixing mistakes and poor work from two other plumbers, but now I know i've finally found a trustworthy company, and I will definitely be calling Macmillan next time I need a plumber.
