Keeping your house warm makes it far more enjoyable to live in.

This applies to all parts of the property that you spend time in.

When you convert your loft into a liveable room, it can be a bit chilly to start with.

Luckily, insulation can fix that.

What is loft Insulation?

Loft insulation is insulation added to your property’s loft or attic space. You add this insulation to the floor, walls, and ceiling.

The goal is to keep heat inside the area and stop it from escaping.

You have several different options for materials to use. Mineral wood, fibreglass, and foam are all good options. 

Most people invest in loft insulation because this is naturally one of the coldest rooms in the house. If you want to spend many hours in there, adjustments could be needed.

It’ll also increase the value of your property.

Your loft insulation will usually be put in one of two places. Between the joists (horizontal beams forming the loft floor) is one option. Another is between the rafters (angled beams supporting the roof).

The thickness of the insulation will depend on the material used and the level of energy efficiency you want to achieve.

The expert you pay to do the job can advise on this. UK government recommendations suggest a minimum insulation depth of 270mm for optimal results. 

Reasons to get insulation in your loft

Energy savings

Loft insulation helps keep heat inside your home, reducing the need for constant heating.

This can lead to significant savings on your energy bills, especially during the colder months. 

Comfort

A well-insulated home is more comfortable to live in. It stays warmer in the winter and cooler in the summer. This provides a more stable and pleasant indoor environment for you and your family. 

Environmental benefits

Reducing your energy consumption will also reduce your carbon. This is essential for homeowners who want to live more sustainably.

Soundproofing

Insulation materials can also help to reduce noise transmission through your roof. This can be particularly beneficial if you live in a noisy area. Near an airport or busy road are great examples. 

Condensation reduction

Insulating your loft can help to reduce condensation and moisture buildup in your home. This is because the insulation keeps the warm air inside.

It prevents it from meeting the cold surfaces in your loft and forming condensation. And it can help you improve ventilation, as the warmer room will enable you to open windows more often.

Loft insulation costs

On average, insulating your loft costs around £800 in the UK. It’ll cost less (approximately £600) for a smaller surface area, and inexpensive materials. But for the largest projects, expect the price to go over £1,000.

Material and surface area are the two biggest impacts on cost. Your location and professional are important, too. Most experts charge per square metre or feet. 

And the more expensive materials will hopefully do a better job of keeping your house warm. This could add to your property value and save on energy cost long-term. It’s a careful balancing act.

You should get a no-obligation price quotation from an expert before you commit to the project. You could also research whether government grants or loans exist to pay for this work. Many eco-friendly initiatives have existed like this over the years.

Do I need planning permission for loft insulation?

You will likely not need planning permission to insulate your loft.

This is because it’s considered a minor home improvement that does not alter your property’s external appearance or structure. But, there are some exceptions to this rule. 

If your home is listed or in a conservation area, you may need permission. The same could apply if you convert your loft into a liveable space.

In that case, you will likely need planning permission and approval for building regulations. 

It’s always best to check with your local planning authority before starting any work. This ensures that you follow all necessary regulations. 

Loft insulation and property value

When done well, loft insulation will increase your property value.

A well-insulated home is more attractive to potential buyers. They’ll inherit a property that’s energy-efficient and cost-effective to warm up. 

The exact amount that loft insulation will increase your property’s value is difficult to quantify.

It depends on your property condition, the local housing market, and the energy efficiency of similar homes in your area. Up to 5% increase is typical.

Can you do a loft insulation myself?

If you’re a competent DIYer, you can insulate your loft yourself. The process is straightforward and requires no specialist skills or tools. 

You’ll need to buy the insulation material. This is widely available from home improvement stores. And then follow the manufacturer’s instructions for installation. 

It’s crucial that you take health and safety measures. A dust mask, gloves, and long-sleeved clothing are essential. Insulation materials can irritate the skin and lungs, so it’s crucial to protect yourself. 

If you don’t have the skills, time or materials to do it yourself, hire an expert.

This can give you reassurance and financial protection if something goes wrong, due to their indemnity insurance. It will add more value onto your house when done well.

Tips to find a reliable company for loft insulation

Look for accreditation

Choose a company accredited by a recognised body, such as the National Insulation Association. This ensures that they are trained and will adhere to industry standards. 

Check for experience

Look for a company with a successful record of completing loft insulation projects. You can ask for examples of their work or read testimonials from past clients. 

Get many quotes

Gather quotes from several companies to ensure you get a fair and competitive price. Be wary of quotes that seem too low. It could signify a company cutting corners or using substandard materials. 

Ask about warranties

A reputable insulation company should offer a guarantee on the materials and workmanship. This gives you peace of mind and protects you if any issues arise after the installation. 

Read the contract carefully

Before signing any contract, read it to understand what’s included. Be bold and ask questions if anything needs to be clarified.
