Affiliate Disclosure

Some pages on buildwiz.uk include affiliate links to UK suppliers such as Amazon and building merchants. If you click one of these links and buy something, we may earn a small commission. It costs you nothing extra: the price you pay is exactly the same.

These links are marked as a “Where to buy” block and use the rel="sponsored" attribute, in line with search engine and UK advertising guidance. We only add them to pages where showing you where to buy a product is genuinely useful.

Affiliate commission does not change what we recommend. The guidance on this site is based on real UK building practice and a documented extension build, not on which supplier pays the most. If a cheaper or better option exists elsewhere, we would rather tell you than steer you to a link.

Affiliate income helps keep the free knowledge pages free. If you would prefer not to use the links, you can always search for the product yourself. Either way, the content is the same.
