How delivery works in Hemel Hempstead

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

• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

A quick quantity check

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

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

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.
