Customers Love Palace Plumbers


I've used other local plumbing companies in the past but will continue with Palace Plumbers from now on. The office staff are very helpful and the engineers have been on time every day to install my new boiler.


Taz, the plumber who visited, was very courteous and managed to fix my shower and toilet in just over an hour. The time went slightly beyond the hour but I wasn't charged any extra for this.

Henry Fullerton VERIFIED

Boiler repair was carried out swiftly. It's been 2 weeks and my heating system is working better than ever. I've already booked up my annual service for later in the year. 2 thumbs up.
