How delivery works in Horley

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Horley is inside our standard mainland delivery area.

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Things to check before you order

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.

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.
