The end result was a master class in plumbing

I want to give a big shout out to the men who installed my hot water cylinder, namely Patraic and Jake.
They arrived before 7:30am and worked solidly all day.
The end result was a master class in plumbing. Unfortunately there seems to be a distinct lack of plumbing skills these days.

I’m so pleased with the installation that if I ever sold the house I would take potential buyers to the airing cupboard and use it as a USP!

The whole process was so professional from Becky taking the initial call. Patraic coming the same day. Quote the next day. Installation the following day!

The company just shows other companies how a business should be run.

Thank you so much.

Knowledgeable, professional and excellent customer service

DCR's heating team are knowledgeable, professional and have excellent customer service, from initial contact with Charlotte and the office based team, through to Lewis and the team of engineers.  
They've looked after my heating/hot water system for a few years now and have been quick to sort any issues I've had painlessly and quickly. Exactly the sort of service that keeps me a happy customer.
