It has been one
year, since I calculated and invested into the loft insulation.
At the time I spent
about 750 GBP and 5 days to put the insulation up in the loft (including cleaning
it and teak oil application to the beams and joists to protect them). I also estimated
that 20% of the heat loses were going through the roof.
The actual natural
gas consumption in 2016-2017 was 24,500 kWh (at 4.28p per kWh + 14.80p standing
charge a day) or 1,104 GBP a year.
Since I installed
the loft insulation 2017-2018 consumption was 16,400 kWh (at 4,46p per kWh +
19.18p per day) or 8,100 kWh less (30% reduction) at the cost of 760 GBP. This is a saving of 344 GBP a year.
This means that I
will get my money back in just over 2 years.
I overpaid my utility company by
500 GBP so far. Only after I contacted them, they bothered to cancel couple
of the monthly payments to reduce their debt to me.
The natural gas
prices went by 5% up in the UK last year, making them among the most expensive
in western europe. No wonder that the propaganda encourages people do not heat their homes, including leaving some of the rooms
unheated and keeping others at 61F (16C) in the winter.
Observation:
In 2016-2017 I paid
507 GBP per 1,000m3 of natural gas (circa $700 USD per 1,000m3).
In 2017-2017 I paid
5% more or 532 GBP per 1,000m3 of natural gas ($700 USD per 1,000m3 as the
British pound collapsed towards most of the world currencies).
This is at the time
when Gazprom supplied natural gas prices averaged $190 -250 USD/1,000m3.
Somebody is making 300% profit in the UK on selling me the natural gas. I can agree that some portion of it is inefficiency,
greed (corruption).
