Things to check before you order

Foul or surface water?

Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.

Covers for the location

Chamber covers are rated for loads, from pedestrian areas to drives. Tell us where each chamber sits.

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.

How delivery works in St Helens

Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. St Helens is inside our standard mainland delivery area.

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• On busy streets in St Helens, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
