Working out quantities for your Sunbury-on-Thames job

For a 900 mm clear opening, add at least 150 mm of bearing at each end: the lintel needs to be at least 1,200 mm long. Then pick the type for the wall build-up and check the load in the manufacturer's table, or ask your engineer if the opening carries a floor or roof.

Things to check before you order

Steel or concrete?

Steel cavity lintels support both leaves and include insulation to limit cold bridging. Concrete lintels are simple and robust for single leaves and internal walls.

Which lintel for my opening?

Measure the clear opening, add the end bearing each side, and note the wall type (cavity width, inner and outer leaf) and what sits above. Manufacturers publish load tables; for anything carrying a floor, roof or point load get an engineer or building control to confirm.

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.

• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• On busy streets in Sunbury-on-Thames, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Your questions answered

Are steel lintels insulated?

Cavity wall steel lintels usually have insulation inside to cut heat loss at the opening. Single-leaf and box lintels may not.

Can I add other materials to my Sunbury-on-Thames delivery?

Yes. Put everything on one list, from lintels to fixings and PPE, and we will price it as one delivery where the products can travel together.

Can you tell me which lintel to use?

We can suggest options from the manufacturers' load tables based on the opening, wall type and load you describe, but for anything structural the final choice should come from your designer or engineer, and be approved through building control.
