looking at the two given unit prices of electricity, unit price 18.35 and electricity price 11.06875, i assume that they are giving economy 7 night and day figures and then assuming again that the storage heaters were turned off and the entire heating and dhw demand met using direct electric heating at peak price to get the inflated figures. 11530 kwh x £0.1835 = £2115.755 As a comparison they also quoted £7000 to replace a boiler.

Estimated cost per unit of fuel 18.35 (I'm not sure what this unit price was referring to) Estimated energy required 11530 kwh space heating 8927 kwh DHW 2603 kwh Estimated current cost £2115.76 Assumed electricity price 11.06875 p per kwh Estimated heat pump running cost £396.06 year 1 saving £1719.70 year 2 saving £1836.64 year 3 saving £1961.53 year 4 saving £2094.91 year 5 saving £2237.37 year 6 saving £2389.51 year 7 saving £2552.00 I have not bothered to check if their calculations even add up correctly, everything about the quote was ridiculous.

A similar but slightly different experience, this company went down the RHI route rather than mcs certification. During the booming boiler replacement scheme season (Wales) last year, following a knock on the door the below quote was provided for a rental property with storage heaters. The company also offered free loft insulation.

Total Yearly savings estimate £14,791.66 Total savings and returns £22,989.33 As far as i could see the estimate did not include a central heating system which would make the quote even higher, and the savings seemed a little over the top given that the total electricity bill was around £1000 annually, although admittedly the storage heaters did not adequately heat the property for that cost. All this and more was available for installation within 2 weeks of agreement subject to full heat loss calculations within a week costing £250 as long as it could be agreed during the day of quotation for some random reason. Conveniently finance could be provided through their own bank. Needless to say the quote was not accepted, although i have no others to compare it to it did not seem reasonable.
