Delivering ballast and gravel in Harrow

Bulk bags are usually lifted off by crane where access allows; tell us where they can sit and whether the ground is firm. Harrow is inside our standard mainland delivery area.

• On busy streets in Harrow, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
