Loft Insulation Grant in 2024

Loft Insulation Grant

Most houses have an accessible loft/attic. Studies have shown up to 25% of total heat loss from a property is from loft space and roof. This is one of the easiest, quickest to install and cheapest energy efficiency measure. Main benefits are;

About a quarter of the heat is wasted through the roof of an uninsulated house. Insulating your attic, loft, or flat roof is an efficient way to limit heat loss and decrease the cost of heating.


If installed correctly, the loft insulation can pay for itself several times throughout its 40-year life.

Loft Insulation Selection

If your loft doesn’t have condensation or damp issues, insulating it is simple.

You can use mineral wool rolls if the loft is easy to access and built with standard joists.

One layer of insulation will be laid on top of the joists – horizontal beams that comprise the loft’s floor.

The second layer is laid at precisely right angles so that it covers the joists.

This will build the insulation up to the necessary depth.

Loft Insulation Dos and Don'ts

DOs:

  1. DO wear protective clothing, such as gloves and a mask, when handling loft insulation, as it can be irritating to the skin and respiratory system.
  2. DO make sure you have enough insulation to cover your loft space to the recommended depth for your region. The recommended depth in the UK is typically 270mm.
  3. DO ensure that any gaps or holes in the loft are sealed before installing the insulation to prevent heat loss and moisture buildup.
  4. DO ensure that loft insulation does not block any vents or air bricks in the loft, as these are important for ventilation.
  5. DO consider using natural, eco-friendly insulation materials, such as mineral wool insulation, which is more sustainable and have a lower environmental impact than synthetic materials.

DON’Ts:

  1. DON’T install loft insulation over existing insulation if it is wet or damp, as this can lead to mold growth and further damage to your home.
  2. DON’T install insulation around light fixtures, as this can be a fire hazard. Instead, leave a gap of at least 75mm around these areas.
  3. DON’T compress the insulation, as this can reduce its effectiveness and lead to heat loss.
  4. DON’T cover any water tanks or pipes with insulation, as this can cause them to freeze and burst.
  5. DON’T install loft insulation without checking the condition of your loft first. If there are any signs of damp, mold, or structural issues, these will need to be addressed before installation.

Pipes, loft hatch and water tank

The insulation between the joists in your loft can keep your home warm and makes the space above freezing.


This means that pipes and water tanks in the loft are more susceptible to freezing and you’ll need to shield them.

If the water tank is located some distance away from the hatch in your loft, you’ll need a walkway to ensure safe access.


The cooler air inside the loft you have insulated may result in cold draughts coming from the roof hatch.

To stop this from happening, install the attic with insulation. You can also apply a draught-proofing strip on the hatch’s edges.

How to Insulate a Loft Hatch

Insulating your loft hatch can help to prevent heat loss and improve the energy efficiency of your home. Here’s how you can do it:

  1. Measure the size of your loft hatch to determine how much insulation material you will need. You can use mineral wool, fiberglass or foam board insulation, depending on your preference and budget.

  2. Cut the insulation material to the size of your loft hatch, leaving a small gap around the edges to allow for ventilation.

  3. Attach the insulation to the hatch using adhesive tape or glue. If using foam board insulation, you can also use screws or nails to hold it in place.

  4. Cover the insulation with a piece of plywood or other board material to protect it from damage.

  5. Install weather stripping around the edge of the loft hatch to create a seal and prevent drafts.

  6. Consider adding a hatch cover or blanket to further improve insulation and prevent heat loss.

Remember to wear protective clothing, such as gloves and a mask, when handling insulation materials, as they can be irritating to the skin and respiratory system.
