Everything on Zyrolin is written and edited by one person. This page exists so you know who that is, and what he is and is not qualified to tell you.
What I am not
I am not a plumber, an electrician or a heating engineer. I hold no trade qualification and I am not going to pretend otherwise, because the first reader who checks would be right to stop trusting the rest of the site.
What I actually do
I build websites. Zyrolin is one of them, and it exists because of a problem I kept hitting while researching it: ask what a job costs and you get either a number with no working behind it, or a page written to sell you the job. Neither tells you how the bill is put together, which is the only thing that lets you judge a quote when it lands.
So that is the job I have given myself here. Not to be the expert, but to do the part most pages skip: gather what the energy agencies and the manufacturers actually publish, work out what it means for a household, and lay the structure out in plain language. Where the honest answer is that it depends on your own bill, the article says so and shows you the arithmetic to run it yourself.
How I handle numbers
- Proportions and ranges rather than regional prices, because labour rates and permit fees differ enormously between places.
- Published figures from energy agencies and manufacturer labels, cited and linked, rather than numbers repeated from other blogs.
- A visible note when a figure is representative rather than measured.
Corrections
If something here is wrong, tell me and I will fix it and say that I did. Write to adrian.contact.me.69@gmail.com with the page and what looks off. Corrections get answered before anything else.
