How Much Difference Does Loft Insulation Make in the UK?

loft-difference-hero
  • Loft insulation can save a detached UK home up to £340 in annual energy bills, and even cut their domestic carbon footprint by up to 1 ton a year.
  • Uninsulated lofts are also a key place where noise pollution infiltrates a house. Insulating your loft will provide a more peaceful and private home interior.
  • Homes with loft insulation are often valued higher in the housing market, due to their energy efficiency, lower carbon footprint and more thermally regulated environment.

Uninsulated lofts and roofs can account for more than a quarter of heat loss experienced in a home. That is why loft insulation is one of the most effective home insulation upgrades. Not only does it bring thermal comfort to your home, but helps you save money, benefits the planet, and improves the value of your property, all in one.

But quantifiably, just how much better is an insulated loft in comparison to an uninsulated one? This ultimate GreenMatch UK guide will answer just that, covering all aspects of loft insulation benefits from bills to sustainability, and even market value.

Does loft insulation make a difference?

loft-difference-pros

You might be wondering; how much of a difference does loft insulation make? Many prospective homeowners are unsure of whether loft insulation is worth it, especially when they see the investment it could take. We get it. However, loft insulation is a home upgrade with a wealth of benefits, improving your home's thermal efficiency, savings, and property value. 

What about other qualities? Is loft insulation fireproof? Moisture-proof? Depending on your chosen insulation material, not only will loft insulation benefit you, but also increase the safety and security of your property for decades to come.

Let’s have a look at some of the key perks you could enjoy by properly insulating your loft:

Savings on your heating bill

Does loft insulation make a big difference in your savings? Absolutely. The most attractive advantage of loft insulation is that it will improve your home’s thermal efficiency, meaning your heating system won’t need to work constantly to top up lost heat. This less use will translate to more savings on your energy bills.

Here’s a breakdown of the cost of loft insulation, as well as just how much you could save per type of household in the UK:

Home typeAverage installation costs  (£)Energy bill savings (£/year)
Mid terrace home£900£180
Semi-detached home£950£200
Detached bungalow£1,200£330
Detached home£1,200£340
These values are obtained via Energy Saving Trust UK (July 2024). For more accurate prices, get a local installer to QUOTE now!

In most cases, this also makes loft insulation one of the quickest payback times on an investment, often able to pay itself off within 10 years. Some homes can even qualify for a loft insulation grant to further help with the investment.

Carbon footprint

An uninsulated loft is responsible for over a quarter of home heat loss. Alongside wasted energy, this massively increases your home's carbon footprint. By properly insulating your loft and improving thermal efficiency, you also reduce the harm your home accrues to the planet.

You may be wondering, just how much do I help the planet with loft insulation? We’re here to show you just that: 

Home typeCO2 savings (kgCO2/year)
Mid terrace home550
Semi-detached home600
Detached bungalow1,000
Detached home1,000
These values are obtained via Energy Saving Trust UK (July 2024). For more accurate prices, get a local installer to QUOTE now!

A detached UK home or bungalow can cut its carbon footprint by a staggering 1 ton a year, making this a highly sustainable and environmentally friendly home upgrade. 

Tip: Work with sustainable materials!

Another way to further improve your home’s environmental consciousness is to work with more sustainable insulation materials. While there is no single best insulation for loft purposes, materials such as sheep wool, cork boards, and cellulose boast some great sustainability and recyclability qualities worth considering.

Extra space

Loft conversions allow you to maximise the use of space in your home without having to extend the actual footprint of your home. By turning your existing loft space into an insulated and liveable area through loft insulation between rafters, you create more space for comfort and leisure for a fraction of the cost of a whole extension project.

Alternatively, your loft can serve as a storage space for your home, eliminating the need for a storage unit or external space to be made.

Increased property value

A key benefit to any home insulation upgrades, especially loft, is that it will make your home more attractive to potential buyers and renters in the housing market. 

Homes that are insulated are more comfortable to live in, have lower energy bills, and do not suffer from condensation issues. Therefore if you ever decided to put your house up on the market, you’d enjoy the higher end of price ranges.

Quick installation

Loft insulation is one of the quickest home upgrades, and still packs a wealth of benefits for your home. An average loft insulation job shouldn’t take more than 2 hours to complete by a professional installer. 

Of course in exceptional situations where existing repairs need to take place, this duration can be longer, but considering the positive impact of loft insulation on your home, it’s worth it.

Reduced noise pollution

While thermal insulation materials are not necessarily designed to be soundproof, insulating your loft will bring about improved acoustic insulation, both blocking noise pollution from outside, as well as enhancing your home privacy by keeping noise inside.

By choosing blanket-style materials like mineral wool or cotton, you can further insulate your home for both thermal and acoustic comfort.

Is getting loft insulation the right choice for your home?

Now the key question; is loft insulation worth it? With all things considered, loft insulation emerges as one of the most impressive home upgrades one could take on. With its accessible price range, energy bill savings, and enhanced home comfort, it’s a must-have for all homes.

However, finding the right installer at the right price can be a harder task than expected. Sifting through the endless sea of loft insulation installers can have you spending hours on end with no bargain in sight. Luckily, GreenMatch UK can free you from this burden.
