Great Service

Great friendly service, called due to an emergency at home and took my call straight away and thankfully were able to send someone out that day. They were able to sort the problem and get my heating back up and running.

Unprofessional service.

Absolutely unprofessional service. I called last Thu morning to book someone for broken boiler. I was told someone would call me back to confirm the appointment time. Nobody did, I had to. At the end someone came that day to check the boiler but couldn't figure out what the problem was. Then came back an hour later and promised to call later the same day to give the estimate price for the broken part and work. That didn't happen. Again it was me who was calling multiply times next day. No answer. Zero. Of course nobody called back. No contact since then. One phone call explaining that it's too difficult to fix would be enough. I would look for different options and not waste time. Complete rubbish.
