Online Plumber Reviews

Macror Plumbing has looked after all our heating and plumbing issues for 13 years now. I cannot rate them highly enough. I’ve never had anything other than excellent service from them . Rory and his team are just fantastic .

Excellent service - always ..

Rory came to carry out my annual gas combi boiler service. Never have I ever in over 20 years witnessed a more thorough boiler service which took Rory way over an hour – he even wiped out the dust on the inside of the boiler!
Payment of the going rate was taken by card after – perfect!
I have highly recommended Rory to all my friends and family and asked him to give me quote for renovating my bathroom next.


The whole team at Macror are a delight to deal with …. Wonderful Wilma is always pleasant & gets you booked in pronto Then the “on The Tools Team” perform their Magic & make All that is Broken work Again …. Better then before!!! 😊 Can’t recommend Macror highly enough. Thank You 👏🏻

Rory and the team have completed several jobs for me over the years from new radiators to flushing the system or fixing leaks. Very knowledgeable and helpful, it’s good to have a small local business that you can trust.

Very tidy installation of new Worcester Bosch boiler and associated pipework to new water main in Garden Square flat in Central London. Would recommend.


Have used Macror for a few years now and they have never let me down. they have been efficient, polite and speedy and always offer sound advice rather than just try to get a job. Highly recommended.

I don’t mind endorsing these guys as I have been stung enough times with various plumbing jobs by other firms. Rory and co turn up on time and do the job at a fair price which is what you want and don’t always get from many traders. Cheers guys

I started to use Rory and Macror Plumbing 15 years ago for the plumbing and boilers in our flats. He and his employees have always been fastidious in their attention detail, professional hard work and addressing safety. Previously the boilers were my No.1 concern to do with the flats but now I am completely confident that they are properly installed, really well maintained and breakdowns will be sorted out at the first call. In addition Rory has provided excellent advice on plumbing and boilers. Very helpful.
