Energy Cost Savings from Wall Insulation

CUTTING  HEATING BILLS

Whilst it can seem that every man and his dog are  shouting  from the rooftops about the value and efficiency of home insulation there is precious little detailed information on the pounds, shillings and pence that can actually be saved in particular from insulating cold solid walls.

Whilst every home uses their heating in different ways with varying temperature and timing settings it is possible to extrapolate certain guide line cost savings beased around authoritative bodies who publish independant figures based on serious scientific research.

HEATING COST REDUCTIONS – REALISTIC EXPECTATIONS


The following figures are based around a 5% annual price rise :

House    10yr Saving    Annual Saving at 10 yrs   20 year Saving        Annual Savings at 20 years

semi          £ 5,231       £ 620                           £ 13,841                        £1,061

det’d        £7,546            £ 977                         £ 20,006                      £1,516

Whilst these figures are purely a projection at 5% per annum increases in heating bills we believe they are very conservative especially when compared to increases in the last 4 years . In fact the above assumes about a 50% increase in energy costs in 10 years time when we have seen this size of increase in the last few years alone.

DON’T TAKE OUR WORD FOR IT !!

The above fuel savings are based around the UK average household  gas consumption of 20,500kw/h from OFGEM and the Energy Saving Trust’s average energy cost savings of £400 for a standard 3 bed semi using gas central heating that undertakes solid wall insulation

The Energy Saving Trust assess a 3 bed semi as having around 75 m2  to 80 m2 of net wall area and from our experience that is an accurate figure with a 3 bed detached having around 120 m2 of  net surface area . The heating bill savings are based on these figures.

REALITY CHECK

As for future price rises we do know that Ofgem have predicted a miniumum 20% rise by 2020 as a direct result of the  Energy Companies passing onto consumers the extra investment costs incurred to meet the legally binding Carbon Reduction targets and guarantees of future stable gas /oil supplies.

Throw into the mix the far greater costs of extracting oil from the new fields in the arctic and the extreme depths in the Gulf, along with increased demand from the likes of China and India,  and it is clear that the cost of oil and therefore gas will continue to climb.
