The top 5 ceiling insulation services in Canberra that helped slash my electricity bill By William Munro
If you’re like me, you’ve probably cursed your power bill at least once every winter. When I first moved into my house in Canberra fresh out of college, I didn’t realise just how much heat was being lost through the ceiling until I finally decided to get ceiling insulation done.
After trying a few options and speaking to locals, I’ve narrowed down the best ceiling insulation services in Canberra for homeowners and builders who want comfort without the cost.
So, whether you’re building a new home or retrofitting an old one, let me walk you through what I’ve learned and how you can find the right team to do the job.
How much does ceiling insulation cost in Canberra?
On average, ceiling insulation in Canberra ranges from $35 to $55 per square metre, so for an average home, expect to pay around $1,500 to $2,500. The price depends on the type of material (glasswool, polyester, earthwool, etc.), the R-rating (thermal resistance), and whether installation is included.
1. Alexander Watson Insulation

Address: 3-4/76 Hoskins St, Mitchell
Phone: 02 6181 2750
Business hours: Monday to Friday, 8:00 am – 4:00 pm
I honestly didn’t expect a local insulation company to feel this polished. Alexander Watson Insulation stands out with their comprehensive range of sustainable insulation solutions, including earthwool, polyester, and glasswool, all from trusted brands.
Their free onsite assessment is thorough, and the team goes the extra mile to recommend the best fit based on your home’s layout and orientation.
Installation was swift and non-disruptive. What really impressed me, though, was their detailed quote and the cleanup afterwards, no loose batts or debris left behind.
Prices were on the higher end, but the materials are of top quality and backed by a 50-year warranty. They also don’t work weekends, so booking a slot might need some planning.
Friendly, professional, and knowledgeable
“I can’t speak more highly of Alexander Watson, every single person that came to our house was friendly, professional and knowledgeable in what they do. They clearly have a great company culture and great team across both insulation and electrical. Our house is warm, safe and one thing one didn’t expect quieter. I run my own business in Canberra and aim to have this level of service. Well done.”

Superb communication
“We had Watson’s come and install roof installation at our house. We have a flat roof and all other suppliers had refused to quote on the job. Watson’s came, looked and spoke with us about options and provided quote. They came on time, advised when there was a delay, the workers were all polite and efficient, we needed holes cut in our ceiling for them to be able to fully insulate, they came back and plastered and cleaned up beautifully themselves. I would highly recommend this company and this service. It has made a difference to the temperature in our house.”

2. Cozy Insulation

Address: 9 Darling St, Mitchell
Phone: 043 111 6000
Business hours: Monday to Friday, 9:00 am – 5:00 pm
Cozy Insulation lives up to its name, offering both supply and installation packages. Their ceiling insulation services are tailored for Canberra’s weather extremes — freezing winters and boiling summers.
They use high-performance Bradford and Knauf insulation products that meet strict Australian standards for energy efficiency, fire resistance, and indoor air quality.
What makes them stand out is their easy booking system and fast turnaround time. My friend who used them said their attic went from drafty to snug in a single afternoon.
They also provide ceiling vacuuming if you’re replacing old insulation.
The booking process is simple, but some customers report delays in email replies. Another drawback is that they don’t offer much in terms of insulation-type variety, but for homeowners who just want quality and comfort fast, this is a solid pick.
Thorough and quality service
“Really appreciated the thorough and quality service provided by Cozy Insulation. Brad came out to assess and gave a lot of feedback about how to make the best of how my place was built and situated in terms of insulation. The quote was competitive and Nathan and the crew were friendly and efficient. They noticed a broken rafter during installation (showed me a photo) and then went ahead and fixed it for me. Very pleased with the outcome and noticing the difference, bring on winter!”

Works with care and precision
“Norm and the team did an excellent job with wall and ceiling insulation at my home. Norm and Brad are both knowledgeable and fun to talk to. They work with care and precision, demonstrating a strong work ethic and clear pride in their work. The results were professional and exceeded my expectations. Highly recommended!”

3. B Noticed Interiors & Insulation

Address: Canberra, ACT, Australia, Queanbeyan
Phone: 0403 661 363
Business hours: Monday to Saturday, 8:00 am – 8:00 pm
B Noticed Interiors & Insulation offers both insulation as part of a wider suite of interior services, making them the ideal pick if you’re doing renovations. They install thermal and acoustic ceiling insulation alongside plastering, fit-outs, and soundproofing.
Their attention to detail and ability to coordinate multiple tasks make them a top pick for full-home upgrades. Their team was detail-oriented and respectful of my space, and their ceiling insulation work was both tidy and efficient.
Quotes are affordable and detailed, and they didn’t push for upsells.
However, since insulation isn’t their only focus, you might need to wait a bit longer during the holidays.
Smooth installation
“Louis and the team were fantastic. We had old ceiling insulation removed, new insulation laid throughout and the entire underfloor done as well. The ceiling space included two raked ceilings which the team managed to navigate (and other companies said couldn’t be done). The quote was competitive and a much better process than the largest provider of insulation in Canberra. Install went smoothly and communication throughout was excellent. When there was a small hole that needed fixing, it was attended to promptly and the job was done flawlessly. Absolutely recommend B Noticed!”

Great communication and service
“Louis gave me a rating for the roof insulation in my Canberra townhouse and then made some suggestions to improve it. He and his team efficiently installed some additional batts in the roof space gaps. This has helped to keep my house warmer in winter. I was very pleased with Louis’ communication and service.”

4. Just Rite

Address: 181 Gladstone Street, Fyshwick
Phone: 02 6280 5300
Business hours: Monday to Friday, 7:30 am – 4:00 pm
With a solid track record since 1977, Just Rite offers a comprehensive energy-efficiency package in Canberra, covering ceiling, wall, and underfloor insulation, plus double glazing and skylight options.
They provide free energy assessments and install high-performance Bradford ComfortSeal batts, which are designed to retain thermal resistance and reduce heat loss by up to 70%. This makes them a solid option for those looking to upgrade their home’s overall efficiency.
While most clients are satisfied with the results, a few have noted that installation quality can vary depending on the team assigned. That said, this can be easy to address by staying in touch with the installers and doing a quick post-installation check.
Overall, their experience, product reliability, and comprehensive services still make them a strong choice.
Caring and professional work
“Fantastic service by Baj, this gentle soul worked on our roof with excellent care and professional manner. We really appreciate your work and dedication. Highly recommended service and staff. We look forward to a warmer house this winter!”

Their service range is impressive, whether you’re after insulation alone or a complete energy solution. That said, they tend to be busiest leading up to the holiday season, so booking early is recommended.
Highly professional, reliable, and easy to deal with
“I was referred to Daddy Sun Solar by my brother to remove and install insulation and I’m really happy with the results. They removed the old roof insulation and installed new insulation in both the roof and floor. The team was highly professional, reliable, and easy to deal with. They arrived on time, worked efficiently, and completed the job as promised. The quality was excellent and the price very competitive. I would definitely recommend them to others.”

Very pleased with service accreditation and knowledge and advice from business. Would recommend Daddy Solor as much needed reputable insulation provider in Canberra.”
