I am an 87-year old person living in my own house. Initially things went well, with an appointment being made within the promised time scale. However, the change out of the boiler was scheduled and then cancelled the day before installation. A second appointment was made for which family travelled the day before to be on-site to assist. The appointed contractor did not appear at the scheduled time, and after various phone calls it transpired that the contractor was not coming and a new appointment would have to be made some weeks later. We thought the next day would be more appropriate bearing in mind my status. Finally, at the third attempt a contractor did appear and carry out the work, with the exception of the wireless thermostat which 'was not on the van'. This item is still outstanding. It took three weeks from initial appointment date to installation, delays which are not acceptable for a vulnerable elderly client.
