About security sheds
A security shed has only small, high-level windows, so light gets in but nobody sees what is inside, and it is built to take a proper lock. Choose a pent or apex roof to suit where it sits.
Compare the roof, door and window layout on each product page, then check availability and delivery details.
Common questions
Is the timber treated?
The timber is pressure-treated and carries a 15-year anti-rot guarantee. Check the guarantee terms for care requirements.
How quickly will it arrive?
Free next-working-day UK mainland delivery applies to eligible in-stock flat-pack buildings ordered by 2pm. Check the delivery page and the availability of your chosen configuration before ordering.
