i think there is more to it than people may think. like everything else, gas boilers are easy to fit its not rocket science, or is it?
First I do agree with your post!
The point I was making is probably best described in a hypothetical case. Suppose Mr. Brand Spanking New Solar Company Ltd visits Mrs Jones who is thinking about renewables. She has a standard boiler and heating setup in her house.
During the course of the 2-3 hour consultation and essay writing competition entry (ie sales pitch) she is sold on the idea of spending £14,000 on a solar heating system. ("Mrs Jones, you have to remember that the cost of the administration has to be covered and the QMS registration process and so on. Also you need to remember that without my qualifications you won't be able to claim from the government under the RHI" ... (Mrs Jones: "What's the RHI again?") ... "Oh that's the blah, blah, blah.
Are there any further questions?"
"Yes, actually, there is. My sitting room doesn't warm up enough. Also the bathroom is too warm sometimes. The heating also comes on in the summer. Are you able to fix these?"
"I'll get my contractors to take a look."
"How much will it be?"
"I'm not too sure."
"Can you tell me the approximate cost as I need to budget for that as well?"
"Oh, I shouldn't think it will cost more than £2,000".
Mrs Jones "What will that cover?"
In other words, Mr. Brand Spanking New Solar Company Ltd has no idea either of the possible problem or the cost to solve it.
It's not rocket science but I do wonder how many of the salesmen of these new companies who have the QMS, REAL, RHI, BSHons, Piano II Merit (passed at 10 years old no less) have any idea on how the basics of heating a house.
