Welcome to Ahead Loft Ladders

You don’t usually need to apply for planning permission to put a Velux / Skylight / Rooflight window in your loft. As long as it doesn’t protrude more than 150mm from the existing roof surface, it falls under ‘permitted development rights’.

There are exceptions for listed buildings, or those in in conservation areas, national parks or areas of outstanding natural beauty.

You should also check with Building Regulations, as this is not the same as planning permission. This will ensure it is structurally safe to add windows to your property.

Installation time can vary depending on a number of factors:

• The type of ladder chosen (wood/metal/electric etc.)
• How easy the attic space is to access
• The condition and position of the loft hatch
• Whether electrical connection is required

In general, with no surprises during the process, we expect a standard loft ladder installation to take around 2-3 hours.

UK building regulations require loft insulation to have a total depth of 270mm for mineral wool (soft insulation). This is to ensure it achieves the recommended U-value* of 0.16 W/m²K.

High-performance insulation boards like PIR require less thickness (120-170mm) to meet the same U-value.

Insulation must not be placed right up to the eaves. Instead, leave a clear 50 mm air gap to allow adequate airflow and prevent damp retention.

*The U-value is a measure of how fast heat escapes through a part of the building. Lower numbers mean better heat retention.

If you use your loft primarily for storage, then a loft ladder is not a legal requirement.

However, A ladder fitted by a professional company like Ahead Loft Ladders can make loft access far easier and safer. If you intend on accessing the loft space regularly, a dedicated ladder is a worthwhile investment.

For converted lofts that are used to increase living space, a permanent fixed staircase in required under UK Building Regulations.
