Our paid order data records 16 Kensington 6ft orders between 1 April and 30 September 2026. The 6x8 toughened model was the best seller, with 7 orders. Toughened glass models accounted for 9 of the 16 orders.

How to choose your Kensington 6ft lean-to
When fitting this range, we recommend measuring the actual 1915mm projection before choosing a length. Size names are projection x length. A 6x8 is nominally 6ft out from the wall and 8ft along it. Its actual footprint is 1915mm x 2578mm. Available lengths are 6ft, 8ft, 10ft, 12ft, 14ft, 16ft, 18ft and 20ft.
We recommend 3mm toughened safety glass where children or pets are around. The alternatives are 3mm horticultural glass and 6mm twin wall polycarbonate. The 6x6 polycarbonate model starts at £1,299.
Silver aluminium is standard, with 10 powder-coated finishes available. Every size has built-in gutters, a 6ft shelf and one louvre window vent. The 6ft to 12ft lengths have one opening roof vent. The 14ft and 16ft lengths have two. The 18ft and 20ft lengths have three.
Check that your wall is sound and vertical before ordering. Plan access around the single sliding door's 600mm x 1750mm aperture. The door can be fitted at either end or in the middle. Read our base preparation guide before preparing the ground. Our greenhouse installation service is another option.
🔧 Matt's installation tip: measure the wall at both heights
Before ordering, measure your wall at the 1800mm eaves and 2400mm ridge heights. Check for pipes, lights, windows and sills along the full length. These heights exclude the optional base plinth.
