Affiliate Disclosure
Last updated: 04/07/2026
Duval Heating Advice is a participant in the Amazon Associates Programme (also known as Amazon.co.uk Associates), an affiliate advertising programme designed to allow sites like this one to earn a small fee by linking to Amazon.co.uk.
As an Amazon Associate I earn from qualifying purchases.
This is the exact statement Amazon requires all participants to display.
What this means in practice
Where I mention a specific product on this site — for example, a smart thermostat or a boiler control — I may include a link to that product on Amazon. If you click that link and go on to buy something on Amazon (not necessarily the exact item linked), I may earn a small commission. This costs you nothing extra — you pay exactly the same price either way, and Amazon pays me directly out of their own margin, not yours.
How I choose what to link to
This site isn’t built around selling products — it’s built around 50 years of hands-on plumbing and central heating experience, and giving people honest advice so they don’t waste money on the wrong equipment. Any product I link to is something I’d genuinely recommend based on that experience. I don’t accept payment from any manufacturer or retailer to feature their products, and no company has any influence over what I write here. The only financial relationship on this site is the standard Amazon Associates commission described above.
Cookies
When you click an Amazon affiliate link, Amazon places a short-lived cookie on your device to track that the purchase came via this site. This is covered in more detail in my Privacy Policy.
Questions
If you have any questions about a product I’ve mentioned, or about this disclosure, please get in touch via the Contact page — I’m always happy to help.
