Maximise Comfort & Cut Costs with Loft Insulation
As energy prices continue to rise, insulating your home has never been more important. Loft insulation is a highly effective way to reduce heat loss, lower energy bills, and enhance overall home comfort. With potential savings of up to £590 per year, and the added benefit of increasing your property’s value by 15–20%, it’s a smart and sustainable investment. Through the ECO4 scheme, Ranova Energy proudly offers free loft insulation grants to eligible households—helping you enjoy a warmer, greener, and more energy-efficient home.
How to Insulate a Loft
Installing loft insulation is simple but must be done properly for maximum impact:
- Clear the space: Remove stored items and ensure access to all areas.
- Protect your plumbing: Insulate any pipes and water tanks to prevent freezing.
- Mind the wiring: Place electrical cables above the insulation layer—consult a qualified electrician if needed.
- Measure & install: Use roll insulation to fill the space between joists (typically 100mm thick), followed by a second 200mm layer laid at right angles for optimal coverage. Aim for a total insulation depth of at least 270mm for best results.
What Is Loft Insulation?
Loft insulation works as a thermal barrier within your attic space. Installed either between the joists (floor level) or the rafters (roof level), it traps heat inside during winter and keeps your home cooler in the summer. Think of it as wrapping your home in a thick, protective layer that reduces heat escape. Choosing the right insulation material is key—Ranova Energy offers guidance to ensure the perfect fit for your home, improving energy efficiency and indoor comfort year-round.
How Does It Work?
The cost of external wall insulation varies by property size. For a three-bedroom semi-detached home, expect to pay between £5,000 and £9,000, while a larger detached home may range from £8,000 to £15,000. Additional work like adjusting pipework or cabling may affect the total cost. However, when combined with other energy-efficient measures, this investment can significantly lower your bills and boost your home’s EPC rating.

A Nationwide Energy Solution
The Great British Insulation Scheme aims to help over 300,000 households access free or discounted insulation. If you’re eligible, you could benefit from a fully funded upgrade at no cost to you. Studies show that good insulation can slash energy bills significantly, making it a vital part of the UK’s push towards net-zero emissions.
Meanwhile, innovations like heat pumps are also becoming essential, with government plans to install 600,000 units per year by 2028—cutting carbon emissions from heating in half and driving us closer to our 2035 climate targets.
Difference Between Warm and Cold Loft Insulation
Understanding the difference between warm and cold lofts helps determine the best insulation approach for your home’s needs, energy efficiency, and future usage of the loft space.
Cold Loft Insulation
Cold lofts are the most common and cost-effective option in UK homes. In this method, insulation is laid between and across the floor joists, which effectively prevents heat from rising into the loft space above.
Advantages:Affordable and simple to install
Effective at keeping heat within the living areas below
Disadvantages:The loft remains unheated and can experience extreme temperature fluctuations
Higher risk of condensation and dampness in the loft space
Not suitable for lofts used as living spaces or storage of temperature-sensitive items
Warm Loft Insulation
Warm lofts are insulated at both the floor level and roof rafters, keeping the entire loft space warm. This setup is ideal for homes where the loft is used as an additional room or for storage.
- Advantages:
The loft stays warmer and more stable in temperature
Reduces risk of condensation
Ideal if you plan to convert the loft into a living area
- Disadvantages:
Higher installation cost
Requires more insulation materials and expertise
