How delivery works in Northwich

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

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• If neighbours share the access, it helps to let them know a lorry is coming.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Getting the right damp proofing

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.

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.
