Which insulation you choose depends on your budget and the size and type of the area to be insulated.

Popular insulation choices include:

• Mineral wool is durable, non-combustible, aids noise reduction and can be inserted on walls and in lofts
• Glass wool is sustainable, efficient and good at reducing energy bills
• Polystyrene insulation boards can be inserted in most places, reduce heat transfer and improve energy efficiency
• Fibreglass is non-combustible, fire-resistant, and mould/mildew-resistant
• Foil insulation is easy to install onto roof rafters, doesn't take up excess space, reduces heat loss and prevents condensation
• Spray foam insulation expands to fill gaps other materials can miss, and works well in awkward roof or wall spaces, though it usually costs more than blown-fibre options

How you insulate your home depends on the placement of the insulation and its materials.

Loft insulation is popular for reducing heat loss, whereas floor insulation is essential for ground-floor rooms.

Cavity wall or solid wall insulation can cut heating costs and improve home comfort. However, you’ll need to check with an insulation specialist or surveyor, as not all walls are suitable for wall insulation.

Draught proofing is a more DIY-friendly form of insulation; you’ll just need to seal gaps around doors, windows, and other openings.

Chat with local insulation installers to understand what insulation services are available in your area and how much they'll cost.

If you've got the know-how and confidence, you can DIY your loft insulation.

But it depends on the type of insulation you're installing; some are easier to install than others. Rigid board, foil, and blanket insulation are more DIY-friendly insulation materials.

Consider hiring a professional insulation installer in Devon for the best results.

You may be eligible for a government grant to cover the cost of loft insulation.

Schemes available include:

• Great British Insulation Scheme provides free or cheaper insulation to help reduce your home's energy bills

• Energy Company Obligation provides funding to help households improve the energy efficiency of their homes

• Home Upgrade Grant (HUG) is a scheme that includes energy efficiency upgrades and low-carbon heating

Always check you meet the criteria before applying for any loft insulation grants.

How long loft insulation takes depends on your loft's size, ease of access, and any job-specific difficulties, so timings vary from property to property. A professional installer can give you an accurate estimate for your job before work begins.
