How to Repair Shed Floor Boards That Have Rotted: A UK Homeowner's Guide

Always use pressure-treated timber, ideally exterior-grade plywood (WBP – Weather and Boil Proof) or tongue-and-groove floorboards designed for outdoor use. This provides superior resistance to rot and insect attack, essential for the UK climate.

Generally, no. Repairing or maintaining an existing shed does not typically require planning permission, as it falls under 'permitted development rights'. However, if you are significantly altering the size or location, or if your shed is in a conservation area or AONB, it's always best to check with your local council.

Key prevention methods include ensuring your shed is on an elevated, well-drained base, maintaining good ventilation (sub-floor and inside), regularly treating all timber with a quality preservative, and keeping foliage away from the shed walls to promote airflow.

While tempting, this is generally not recommended. Covering rot traps moisture underneath, accelerating the decay of the original floor and potentially spreading the rot. It's crucial to remove all damaged timber before making repairs.
