I just thought I would drop you a line as it’s been several months
since the work was completed.
I have had my gas bill through and compared with last years there is already quite a significant reduction in usage. I have also noticed that the central heating hardly comes on at night and my radiators are cooler during the day. Finally when an aircraft flies over the noise is not as intrusive as it used to be.
So all in all I am very happy with my decision to have the work done and with the standard of the work done!
