I've become a user of this forum specifically to report a good experience with the loft insulation service offered by SIG Energy. This was for top up loft insulation (100% subsidised) in the London Borough of Sutton with a team operating from the Reading branch. The work was completed and no mention of any extra charges was made by anybody I came in contact with at any time. I was visiting my now elderly mother when a canvasser called to promote the installation of loft installation. I am wary of cold callers but as this was something that I had in mind I agreed to see the surveyor who was out with the canvassing team. This method of working reflects the experience of others who have posted on this site. I guess that there are many (lowly paid) canvassers doing the door to door stuff and one member of the team to assess whether the insulation can be fitted free. Both the canvasser and the surveyor were polite and not at all pushy, unlike others I have read about in other posts. The information was clear, the information pack left behind gave all the information including the fact that SIG Energy Management use Miller Pattison for their installations. A letter was sent to confirm the installation date which was different from the original provisional one made on the day of the survey but I was able easily to contact the main office and change the date to a more convenient one. A confirmation of the revised date was sent. I wanted to be around rather than have my Mother cope with the visit as it has got to the stage where I feel she would be vulnerable to any poor practice. Only on the day of installation did I look up any forums on SIG energy whilst I was waiting for them to arrive. I was concerned reading the reports of others. However, the two workers arrived within the time window, worked efficiently, completed the job and even included a small area of boarding to gain access to the water tank at no extra cost (even though the letter said that boarding may be chargeable). I was invited to inspect the work before they left. There was no hard sell or soft sell for any other services and the two workers did not even want to be refreshed with tea and biscuits! Overall I have no complaints at all with the way the work was carried out or the original approach of the company. I guess the reputation of the company is only as good as the front line workers who interface with the public but I am happy to report that I experienced none of the problems listed by others in this thread.
