Assume there'd be no need to notify building control?
Nope.
This is probably the best thing to read - https://www.thepebbletrust.org/wp-content/uploads/2023/08/230814_SRG-ed2_Digital-V2_compressed.pdf
page 104 onwards (although I think the whole thing is really useful!)

I've found this page very useful, we're actually planning on using the insulation featured here:
https://www.ecologicalbuildingsystems.com/post/best-practice-approach-insulating-suspended-timber-floors -
I'm about to embark on this (March) and insulating from underneath as access is good.
We're installing 150mm omnifit insulation (depth of joists) which initially will be held by netting until we get some pipework altered and then we're adding a wind tight breathable membrane over the top to reduce the "wind washing".
I'm hoping we're doing it right! Budget is limited hence the omnifit vs anything more spenny. Ideally we'd get the pipework done before but again budget is non-existent for upgrading the heating and we're trying to make the place as comfortable as possible within our means.
We live in a 1930s mid terraced place with suspended wooden timber floors downstairs. There's no insulation under the floor at the moment and would like to get some under there to warm the downstairs up a bit. What do I need to consider? Assume there'd be no need to notify building control?
