Removing & Replacing Loft Insulation in the UK (2024)
- Replacing older loft insulation can boost your property's thermal efficiency, leading to significant energy bill savings, reduced carbon footprint, and a temperature-regulated indoor environment.
- The cost of removing loft insulation hinges on factors such as how complex the job is, or how much insulation there is to remove. Loft insulation removal costs around £300, plus the costs of a skip and a waste removal company.
- With replaced loft insulation, a standard detached UK home can save up to £340 annually on energy bills, and reduce their carbon footprint by up to 1 ton a year.
Like any insulation measure, materials lose their thermal efficiency as time passes. That's why houses with decades-old loft insulation might not enjoy the same perks as those with newer and healthier insulation material.
But just how much might you need to invest to remove and replace outdated loft insulation material? Does old loft insulation need replacing in the first place? This GreenMatch UK guide is just for that and more. Covering everything you need to know, from loft insulation replacement costs to benefits and even DIY tips, you can get the best idea of what to expect when going forward with this upgrade.

Does loft insulation need replacing?
Have you ever wondered to yourself; should I remove old loft insulation? Then you’ve come to the right place.
Loft insulation, like any material, will eventually need replacing. The average lifespan of properly installed loft insulation is typically around 40 years at most, so older homes with outdated insulation may no longer be enjoying peak thermal performance.
By removing and replacing outdated and ineffective loft insulation, you can revive your home’s comfort, increase your energy bill savings, slash your carbon footprint, and even boost the value of your property, making it an all-around worthwhile investment.
Cost to replace loft insulation
The cost to replace loft insulation hinges on several key factors such as the complexity of your loft insulation removal procedure, loft accessibility, any needed repairs, and much more.
Here’s a breakdown of the general cost of removing old loft insulation:
| Type of job | Average cost (£) |
|---|---|
| Loft insulation removal (standard) | £425 |
| Loft insulation removal (spray foam) | £3,200 +- |
| Brand new loft insulation | £900 - £1,200 |
The cost of loft insulation will vary depending on some factors. If you have issues that need repairing in your loft, or you are completely changing your chosen insulation material, your costs for new loft insulation may be higher.
Cost of removing old loft insulation
The cost of removing old loft insulation in the UK can vary drastically depending on the type of insulation material you have in place and the job's complexity.
If you’re wondering how to dispose of old loft insulation in the UK, certain costs are associated with this process. You’ll be expected to hire a skip to store debris and/or a waste disposal company to remove the material.
Generally, there are two scenarios you can expect:
- Standard loft insulation removal costs around £300 for the labour job itself. In addition, there is the cost of hiring a skip, which can vary depending on your location. In the UK, you could expect to pay around £125 on average for a week.
- Spray foam insulation removal tends to cost much more than standard loft insulation removal, at around £40 per m² of material to remove. This can add up to a staggering £3,200 to remove spray foam from a standard 3-bed home. The process can also take up to a week or more to complete.
Spray foam is a very difficult material to remove, requiring labour workers to cut larger chunks first, and then handle the remainder by meticulously removing bits of spray foam by hand. This is why it is more often recommended to work with blanket style and rigid board insulation materials, as they are far easier to carry out old loft insulation removal with these materials.
All in all, the cost of how much to replace loft insulation hinges on a variety of factors, but it's safe to say that the only real spike in costs occurs if you have spray foam insulation in place. If you meet qualifying factors, you can apply for a loft insulation grant which may cover the costs of old insulation removal as well.
Benefits of replacing your loft insulation
Ever wondered; should I replace old loft insulation? The answer is a resounding yes. Replacing outdated and ineffective loft insulation is a very worthwhile investment that brings with it a whole host of benefits.
From your savings to the environment, let’s have a look at some of the perks you can enjoy with brand-new loft insulation:
- Energy bill savings: By insulating your loft with brand-new insulation, you can save up to £340 a year on energy bills. This is because efficient insulation will make it far easier to maintain indoor temperatures, meaning your heating system works far less.
- More space: By revamping your loft space into a liveable area, you can expand your home’s size without expanding its footprint. Loft insulation between rafters is a great way to do just that, by creating a thermally comfortable area to use for living.
- Healthier home: In addition to temperature regulation, effective loft insulation will help reduce condensation issues. This will eliminate mould, rot and mildew growth, bettering the air quality of your home and reducing the risk of respiratory illnesses.
- Improved soundproofing: While thermal insulation is not designed to provide soundproofing, it certainly helps absorb some sound. With new loft insulation, you can reduce outside noise pollution while enhancing the privacy of your home by keeping sound in.
- Better property value: Homes with brand-new effective insulation are more desired in the housing market. Should you ever decide to sell or rent out your home, having effective insulation measures will help boost your property's value.
In addition to these perks, there are some very impressive contenders for the best loft insulation material, with qualities such as exceptional thermal efficiency, long-term durability, moisture resistance, and even fireproof loft insulation.
Ready to enjoy these benefits of replaced loft insulation? The next step would be to find the right professional installer at the right price. This can feel like looking for a needle in a haystack, taking endless hours of your time to research and vet potential options. Luckily, GreenMatch UK can free you from this burden.
