Getting lintels onto your Blackburn site

Lintels are long, so tell us about tight access. Shorter lintels can travel with a mixed load; long steel lintels are handled by hand or crane. Blackburn is inside our standard mainland delivery area.

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• In summer Blackburn gets around 17h 05m of daylight, but early deliveries still beat the traffic and give the longest working day.
• With roughly 7h 25m of daylight in Blackburn around the shortest day, morning deliveries leave more working light for the job.

Getting the right lintels

Do I need a cavity tray?

Over openings in cavity walls, water in the cavity has to be directed outwards. Many steel lintels need a separate cavity tray and stop ends; check the lintel maker's detail.

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.

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.

A quick quantity check

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.

Common questions from Blackburn

How soon can lintels be delivered in Blackburn?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

Do I need building control approval for a new lintel?

Making or widening an opening in a loadbearing wall is structural work, so in most cases yes. Building control or an engineer will confirm the lintel.

Do you deliver lintels to Blackburn?

Yes. We deliver across Blackburn, including BB1, BB2, BB3. Blackburn is inside our standard mainland delivery area. Send your list or call 0800 088 6341 and we will price it delivered to your postcode.

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.
