What is Room in Roof Insulation?
Room in roof insulation involves fitting insulation boards between the rafters beneath the existing plasterboard walls. This type of insulation works by trapping heat within your home, creating a blanket effect.
It allows you to maintain a warm home more easily without consuming as much energy, ultimately saving you money on your energy bills.
Key Benefits of Room in Roof Insulation
- Prevents heat from escaping, keeping your home warmer.
- Creates a cosier, more comfortable space by eliminating cold spots and draughts.
- Insulates the roof space to reduce external noise, offering peace and quiet indoors.
- Provides protection against moisture build-up and reduces the risk of mould growth.
- Delivers a neat, tidy finish with plasterboards, allowing you to decorate the walls as you prefer.

How Does Room in Roof Insulation Work?
Room in roof insulation is installed in multiple stages to ensure maximum efficiency and long-lasting performance:
- Preparation
First, we ensure that your room in roof is completely clean and clear. This is crucial for a smooth installation, free from any debris or clutter, making it ready for insulating materials. - Installation
We then install the chosen insulation materials. The materials are carefully laid down or spread across the loft roof or floor to create an effective barrier to heat loss and keep your home energy-efficient during colder months. - Ventilation Check
We ensure that airflow is adequate to prevent condensation, which can lead to dampness and other issues over time. This step is crucial for keeping your room in roof dry and well-ventilated. - Finishing Touches
Once the insulation is completed, your room in roof is ready for use—whether for additional storage or just to keep your home warmer.
What Room in Roof Insulation Grants Are Available?
Roof insulation is a highly effective way to retain heat, reduce energy bills, and improve your home’s overall efficiency. Without proper insulation, a significant amount of heat can escape through the roof, leading to higher heating costs. Fortunately, government-backed grants are available to help homeowners and eligible households with the cost of installing roof insulation.
ECO4 (Energy Company Obligation) Scheme
The ECO4 scheme is a government-funded initiative aimed at supporting low-income households and properties with poor energy efficiency. This scheme provides financial assistance for roof insulation and other energy-saving measures to help reduce heat loss and lower energy bills.
Eligibility Criteria:
You may qualify for funding under ECO4 if:
- Your home has an Energy Performance Certificate (EPC) rating of E, F, or G, indicating poor energy efficiency.
- You receive certain government benefits, such as:
- Universal Credit
- Pension Credit
- Income Support
- Housing Benefit
- Child Tax Credit
- Your home has little or no roof insulation, making it expensive to heat and increasing the risk of fuel poverty.
If eligible, you could receive fully or partially funded roof insulation, significantly improving your home’s energy efficiency and comfort.
GBIS (Great British Insulation Scheme)
The Great British Insulation Scheme (GBIS) provides insulation grants, particularly for households that do not qualify under ECO4. GBIS focuses on helping middle-income households struggling with high energy bills.
Eligibility Criteria:
You may qualify for GBIS if:
- Your home has an EPC rating of D, E, F, or G.
- You may be eligible even if you do not receive government benefits.
- Your property has poor insulation and high energy consumption.
The scheme provides support for basic roof insulation improvements, preventing heat loss and lowering energy costs.
