Loft Insulation - General FAQ (6)
The cost depends on the size of your home, however, it will usually cost between £150 and £220 – which can pay for itself in about 1 year.
To meet current Building Regulations you need 270mm of mineral wool insulation. 100mm between the ceiling joists and 170mm laid over the joists. However, the greater the thickness of insulation, the greater the energy and cost savings.
Simply push a tape measure or ruler down the side of a piece of loft insulation until it hits the plasterboard ceiling and read off the depth.
270mm is the required thickness of mineral wool. You will need to buy loft legs which case hold decking boards above the insulation, which means you can properly insulate your loft while maintaining a storage area.
Allow about half a day once you have bought the insulation and cleared the loft of its contents. Remember – you will need one layer of 100mm between your roof joists, then a second layer of 170mm on top (cross layered) to comply with current Building Regulations. Measure the area of your loft and look for the packaging label for the area contained in a roll.
We recommend wearing comfortable, loose fitting clothing and gloves. Many lofts are dusty, dirty places, so we would also suggest wearing a basic dust mask and plastic googles which are available very cheaply from all good DIY shops.

Well insulated houses use less energy to keep them warm. This means that less carbon dioxide, a greenhouse gas, is released into the atmosphere from burning of fossil fuels (coal, oil and gas) in our power stations. Global Warming is occurring because large volumes of greenhouse gases – including carbon dioxide – are accumulating in the Earth’s atmosphere. This causes the planet’s average air and ocean temperatures to increase and sea levels to rise, resulting in increasingly severe weather conditions. This effect is called Climate Change and it’s already happening. By improving the insulation of your home, you will be playing your part in reducing the effect of Global Warming.
Insulation has many benefits:
- Your home will be warmer and more energy efficient
- Your should make savings on your heating bills
- You heating system will emit less carbon dioxide, the greenhouse gas that causes Global Warming
- Mineral wool insulation will also reduce outside noise and increase resistance to fire
- Your house will be cooler in hot weather.
I make sure my energy comes from Green sources, like wind and solar panels – surely I don’t need to insulate my home to help the environment?
Well done for using energy from green sources. Renewable energy sources, like wind power, produce electricity and Solar panels can be good for providing hot water, but do not produce water that is hot enough for central heating. But most homes are heated by gas, and when gas is burnt in your boiler it emits carbon dioxide, a greenhouse gas. By improving the insulation of your home, you will be reducing your energy consumption and therefore playing a greater part in reducing the effect of Global Warming.

No, do not insulate directly below your water tank. The warm air from the room below will help prevent your water tank from freezing in cold weather. Do remember to insulate around and above the tank though to prevent the warm air from escaping completely.
