Before you start

Building guides: common questions

Are these guides a substitute for professional advice?

No. They explain the general rules in England so you can plan ahead. Your architect, structural engineer, building control body and local council confirm what applies to your home.

How up to date are the guides?

Each guide shows the date it was last reviewed. We last reviewed them in October 2026. Rules change, so always check the official sources linked in each guide.

Do the rules differ in Wales or Scotland?

Yes. These guides cover England only. Planning and building rules in Wales and Scotland differ.
