What does a loft insulation specialist do?
A loft insulation specialist installs the insulation in your roof space to keep heat in and cut your energy bills. They work with all main insulation types: mineral wool quilt, loose-fill (cellulose or mineral), spray foam, and PIR rigid boards.
The job isn't always a new install. Specialists also:
Top up existing insulation to the 270mm depth recommended by UK building regulations
Remove old spray foam (which can cause issues with mortgage lenders)
Lag pipes and cisterns in the loft
Offer loft boarding over the insulation too, so you keep the storage space
Professional installation is the safer option for most homeowners.
Working at height, achieving the right depth without creating cold bridges, and maintaining ventilation all require experience. Get it wrong and you can end up with damp and mould in the loft.

What to look for in a loft insulation specialist
Check credentials before you hire. Loft insulation done badly can cause damp, mould, and poor air quality, so this is one job where qualifications matter.
Here's what to look for:
Checkatrade membership: Every tradesperson on Checkatrade has passed up to 12 checks and commits to The Checkatrade Standard. They also hold valid public liability insurance.
PAS 2030 and TrustMark: For work funded through a government scheme (Great British Insulation Scheme or ECO4), your installer needs PAS 2030 certification and you'll need a PAS 2035-accredited Retrofit Coordinator overseeing the project.
CIGA membership: Worth checking if cavity wall work is involved alongside your loft insulation.
NAPIT or NICEIC registration: Required if the job involves any electrical work, such as moving or protecting wiring in the loft.
Reviews for loft insulation specifically: Look for reviews that mention loft insulation jobs, not just general building or construction work.

Checkatrade also offers a guarantee for work carried out by our members. It’s there as a helping hand up to £1,000 if the job doesn’t go as planned (eligibility criteria and T&Cs apply).
How much does loft insulation cost near me?
Costs vary by property size, insulation type, and depth. As a rough guide, expect to pay around £725 for basic quilt insulation, or £825 for a semi-detached house insulated to 270mm. Labour typically runs at £250 per day.
Factors that affect the final price include your loft's accessibility, whether old insulation needs removing, and the depth you're insulating to. Government schemes including the Great British Insulation Scheme and ECO4 may cover some or all of the cost for qualifying households.

Loft insulation FAQs
A standard loft insulation job costs in the region of £825-£1,200 for a typical semi-detached or detached home, depending on property size and insulation depth. Detached houses typically fall at the higher end. Get quotes from a few Checkatrade-checked specialists to compare.
Possibly. Government schemes including the Great British Insulation Scheme and ECO4 offer free or subsidised loft insulation to qualifying households, typically those on certain benefits or in homes with low energy ratings. Your energy supplier can tell you whether you qualify.
Loft insulation can be installed any time of year. Many homeowners choose autumn before heating costs rise, but summer works well too: the loft is dry and accessible. There's no structural reason to wait.
Usually not. If existing insulation is dry and undamaged, a specialist can lay new insulation over the top to bring the depth up to 270mm (the UK recommendation). If the existing insulation is damp, contaminated (e.g. old spray foam with moisture issues), or a type that needs replacing, removal is recommended: a specialist can advise after inspection.
Most mineral wool insulation is rated for 40+ years. Spray foam insulation is more variable: some products have been flagged by mortgage lenders as an issue, so always check with a specialist before installation.
