INSULATION GRANTS

Why do I need Loft Insulation?

Since heat rises, approximately 25% of the heat lost in your home escapes through the roof. One of the simplest and most effective ways to reduce your energy bills is by topping up your loft insulation.

The Energy Saving Trust estimates that a gas-heated semi-detached house with proper insulation could save up to £355 annually on heating costs.

In addition to keeping your home warmer during the winter, loft insulation also helps maintain a cooler indoor temperature in the summer.

What is Loft Insulation?

Loft insulation consists of layers of mineral wool or glass fibre matting and can last up to 40 years, paying for itself many times over.

We begin by installing insulation between the ceiling joists and then add another layer in the opposite direction to ensure a minimum depth of 270mm.

Not only can this save you hundreds of pounds annually, but it also helps reduce carbon emissions. A typical semi-detached house can cut carbon emissions by approximately 610kg per year.

What is Cavity Wall Insulation?

There are various types of cavity wall insulation available, but the method we employ involves injecting graphite-enhanced polystyrene beads into the space between the inner and outer walls. By filling this gap, heat loss through the walls is reduced, leading to a warmer home and minimising the risk of condensation and mould.

The use of polystyrene beads ensures the cavity continues to function as designed, allowing any moisture that enters the gap to safely drain away without affecting the interior of your home.

All cavity wall insulation carried out by Green Energy Sense is backed by a 25-year insurance-backed guarantee, providing you with long-term reassurance and peace of mind.

How do I know if I have a cavity wall?

To identify your wall type, inspect the brickwork pattern on the exterior of your home. If you notice only long bricks arranged in an even pattern, you likely have cavity walls. Conversely, if the pattern alternates between long and short bricks, your walls are probably solid.

If the brickwork is obscured, you can measure the wall thickness from a window opening. Walls thicker than 26cm are likely to have a cavity, while those around 22cm (or 9 inches) thick are usually solid. Stone walls are typically much thicker.

If your home has solid walls—or another type, such as timber frame—we can still support you with a solid wall insulation grant for either internal or external wall insulation.

What is Internal Wall Insulation?

Internal wall insulation is installed by attaching rigid insulation boards to the wall or constructing a stud wall filled with mineral wool fibre.

The choice of materials depends on your home’s construction and any prior work that has been carried out.

Our preferred method for internal wall insulation is using filled studs, as this allows the property to retain its natural breathability, maintaining its original design.

All internal wall insulation installed by Green Energy Sense comes with a 25-year insurance-backed guarantee, providing you with long-term peace of mind.

How do I know if I have got a solid wall?

To identify your wall type, examine the brickwork pattern on the exterior of your home. If you see only long bricks arranged in an even pattern, you likely have cavity walls. This pattern can also appear on timber frame properties, which may require internal wall insulation. However, if the pattern alternates between long and short bricks, your walls are probably solid.

If the brickwork is covered, you can measure the wall thickness from a window opening. Walls thicker than 26cm are likely to have a cavity, while those around 22cm (or 9 inches) thick are usually solid. Stone walls are typically much thicker.

If your home has cavity walls, we can still assist you with a Cavity Wall Insulation Grant.

Why do I need external wall insulation?

External wall insulation is primarily used for solid wall properties but can also be applied to cavity wall homes in areas with high levels of wind-driven rain.

Around one-third of heat loss in a home occurs through uninsulated walls. Insulating your solid walls not only significantly reduces heating costs but also improves your home’s comfort.

According to the Energy Saving Trust, insulating solid walls could save approximately £540 per year for a typical gas-heated semi-detached house.

What is external wall insulation?

External wall insulation involves adding a layer of insulation material to the exterior of your property.

This method not only improves energy efficiency but also gives your home a fresh, updated appearance. The insulation can be finished with various options, such as textured, smooth, painted, pebble dash, or even brick slips to mimic the look of a brand-new brick wall.

External wall insulation is the most costly type of insulation and may not be fully covered by the ECO4 grant, potentially requiring a contribution from you. If you’re considering this option, we will confirm the details after completing an initial survey of your property.

All external wall insulation installed by Green Energy Sense comes with a 25-year insurance-backed guarantee, ensuring long-term peace of mind.

Why do I need room in roof insulation?

Since heat rises, approximately 25% of the heat lost in your home escapes through the roof. One of the simplest and most effective ways to reduce your energy bills is by topping up your loft insulation.

Many loft conversions and purpose-built roof rooms constructed before the 1990s were either inadequately insulated or not insulated at all. As a result, these spaces often become too cold in winter and too hot in summer.

According to the Energy Saving Trust, a gas-heated semi-detached house with proper insulation could save up to £355 annually on heating costs.

In addition to keeping your home warmer during winter, room-in-roof insulation also helps maintain a cooler temperature in summer, making the space more comfortable and usable year-round.

What is Room in Roof Insulation?

Room-in-roof insulation involves insulating all areas of the space using materials such as mineral wool batts (similar to loft roll), loft insulation, or rigid insulation boards.

The image above illustrates how these different elements can be insulated effectively.

Not only can this save you hundreds of pounds annually, but it also helps reduce your carbon footprint. A typical semi-detached house can cut carbon emissions by approximately 610kg per year.

Why do I need Flat Roof Insulation?

Since heat rises, approximately 25% of the heat lost in your home escapes through the roof. Many flat roofs were built with little to no insulation. If your home has a full flat roof or an extension with a flat roof, we can upgrade it with insulation. In addition to reducing your energy bills, you’ll also benefit from a new roof covering.

According to the Energy Saving Trust, a gas-heated semi-detached house with proper roof insulation could save up to £355 annually on heating costs.

In addition to keeping your home warmer in winter, flat roof insulation also helps maintain a cooler temperature in summer, improving comfort throughout the year.

What is Flat Roof Insulation?

Flat roof insulation involves adding a layer of insulation on top of your existing roof to create a warm roof.

We install approximately 120-150mm of insulation over the existing roof felt, followed by a plywood deck and a new weatherproof membrane.

Not only can this save you hundreds of pounds annually, but it also helps reduce your carbon footprint. A typical semi-detached house with a flat roof can cut carbon emissions by around 610kg per year.
