• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• On busy streets in Chesterfield, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Is radon protection needed?

Parts of the UK need radon protection in new buildings and extensions. UKHSA radon maps show the areas; building control will tell you what applies.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
