What is Loft Insulation?

Loft insulation is a thermally efficient barrier that separates the loft and the roof, preventing heat from escaping and helping regulate the overall temperature of your house. The government suggests installing loft insulation, which can mitigate up to 25% of heat loss from a household with poor or no insulation.

By preventing heat from escaping through the roof easily, loft insulation can keep the room below warm and comfortable for a longer period, as well as regulate temperature during scorching summers. While its primary purpose is to prevent heat loss, loft insulation can also help reduce a household’s carbon footprint, saving up to 1000 kg in carbon dioxide emissions per year.

Key Benefits of Loft Insulation

Reduces Heat Loss – Helps lower energy bills by improving heat retention.
Year-Round Comfort – Keeps your loft warm in winter and cool in summer.
Noise Reduction – Minimises external noise for a quieter, more peaceful home.
Prevents Dampness & Condensation – Protects your property from moisture-related issues.
Long-Lasting & Cost-Effective – Enjoy savings with insulation that lasts for years.
Energy-Efficient Insulation Material: We use Mineral wool that is an excellent sound proofing and fire-resistant material to choose for your loft insulation.

I recently had the garage converted into a luxurious one-bedroom suite, and I also had an outhouse built, along with soft landscaping and solid wall insulation. I couldn’t be more impressed with the work. From start to finish, the team was exceptionally prompt, reliable, and professional. Every worker on-site was hardworking and genuinely passionate about their job — and this truly showed in the pride they took in every aspect of the finishing.

The craftsmanship was outstanding. The high-quality materials used were evident in the final result, with clean lines, sturdy construction, and a beautifully polished finish throughout. The attention to detail was impeccable, and they ensured everything was completed to the highest standard.

Infinity Energy Organisation also installed my solar panels and battery storage system last year, and the energy savings since then have been remarkable. My electricity bills have dropped significantly, and I now generate and store enough energy to run my home far more efficiently. Their expertise in renewable energy has made a meaningful difference to both my property and my monthly costs.

I am absolutely delighted with everything they have delivered and would highly recommend Infinity Energy Organisation to anyone looking for high-quality building work, landscaping, or energy-efficient home improvements. Their commitment, passion, and exceptional workmanship made the entire experience smooth, stress-free, and truly impressive.

We had External cladding done on our house through this company and I must say it does keep the house warm. We then had an issue with the sealant on the outside of the window and after a phone call they had their team over to sort out the issue. The team was on time and they were very efficient and did a good job so much so that they left the place clean and tidy. With the cold winters it's worth getting cladding as it does make a difference

Response from the owner 16:37 13 Nov 25

Thank you for your feedback! We’re pleased the cladding is keeping your home warm and that our team resolved the issue promptly and tidily.

Very professional, very high quality of work, effective communication throughout. Every builder or tradesman we’ve had since we’ve had our render done by Infinity has commented on how good it looks and they can tell it’s high quality. During the works they were very careful not to damage our new windows and even came with their own portaloos! Would definitely recommend them

I have recently had my two-storey Victorian terraced house done on the external and partial internal wall insulation by the Infinity Energy Organisation. It is a mixed commercial and residential property so the arrangements of the survey and the building works were complicated.

Harshit, who conducted the building survey, had worked hard with great patience to find solutions to keep all parties satisfied.

The work started and finished as promised in 3 weeks. They arrived on time every day, and kept working tirelessly till the end. They always laid down protection sheets on floors. There were insulation team, electrical team, and people at the office to coordinate, making sure the project went seamlessly. There were small issues after completing the job, but with communication, the issues were fixed straight away.

I am very impressed with their good team spirit and efficiency. The result of the work is high quality. I have no hesitation to recommend this company to anyone who would like to improve their homes on energy.

How Does Loft Insulation Services in London Work?

Loft insulation is installed in multiple layers to ensure maximum heat retention and reduced energy bills.

Preparation
First, we ensure that your loft 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 loft dry and well-ventilated.
Finishing Touches
Once the insulation is completed, your loft is ready for use—whether for additional storage or just to keep your home warmer.

What Loft Insulation Grants and Schemes are Available in London?

Loft insulation is a cost-effective way to retain heat, lower energy bills, and improve your home’s efficiency. If you are struggling with rising energy costs, you may be eligible for a government-backed insulation grant.

ECO4 (Energy Company Obligation) Scheme

The ECO4 scheme is a government-backed initiative aimed at improving energy efficiency in low-income households. This scheme supports those living in properties with poor insulation by providing financial assistance for loft insulation and other energy-saving measures.

Eligibility Criteria:
You may qualify for funding under ECO4 if:

Your home has an EPC (Energy Performance Certificate) rating of E, F, or G, indicating poor energy efficiency and high energy costs.
You receive certain government benefits, such as:
Universal Credit
Pension Credit
Income Support
Housing Benefit
Child Tax Credit
Your home is poorly insulated, making it expensive to heat and potentially putting you at risk of fuel poverty.

If eligible, you could receive fully or partially funded loft insulation, helping you reduce heat loss and cut down on energy expenses.

GBIS (Great British Insulation Scheme)

The Great British Insulation Scheme (GBIS) is another initiative aimed at providing insulation grants, particularly for households that do not qualify under ECO4. Unlike ECO4, GBIS extends eligibility to middle-income households struggling with high energy bills.

Eligibility Criteria:
You may qualify for the GBIS if:

Your property has an EPC rating of D, E, F, or G.
You may be eligible even if you are not receiving government benefits.
Your home has poor insulation and high energy consumption.

This scheme focuses on homes that need basic insulation improvements, helping to prevent heat loss and lower energy costs.
