The Top 5 Cavity Wall Insulation Services in Manchester for Year-Round Warmth!
Once the winter season begins, we all start covering up with thick coats and bobble hats. But it should be done only when we’re outside, because freezing inside our homes isn’t the most ideal scenario, is it?
When I noticed my home wasn’t as warm as it used to be, I was puzzled. Turns out, the insulation in my house wasn’t doing its job properly… and imagine my shock (and horror) that there was an ant infestation inside the walls. Blimey!
That’s disgusting, and expensive in the long run—can you imagine my energy bills? If your home isn’t warming up as it should, get that wall checked! Here are the best cavity wall insulation services in Manchester for a cosy and insect-free home!

What stands out about Cooney Insulations is their straightforward approach: easy, clear, and no faffing about. They know what they’re doing, given their over 25 years of experience and their professional affiliations (IAA and CIGA), to remain fully compliant.
They concentrate solely on insulation, catering to the UK, which means installation and extraction are all sorted out. And during our client surveys, we were impressed by how careful and detailed their work was.
For instance, their extraction jobs were thorough and clean, as they tidied everything up. Their installation was spectacular as well, especially when clients noticed a significant difference in their indoor temperature.
Plus, their no-obligation surveys are helpful to see if your home is qualified for cavity wall insulation. Their team was quick to respond, except on weekends when they’re closed, and were honest without pushy sales tactics.
Budget-wise, they’re a sound choice. Their quotations were reasonable for the area and worth every pound.
Great from start to finish
“Cooney Insulations have been great from start to finish. They came to my home to carry out a survey, then after seeing the results arranged to replace the missing cavity wall insulation. The two men that came, (they did give their names but I’ve forgotten them – sorry guys), were lovely, they were friendly and explained everything; from what the original issues were, to what they were going to do. Then once finished they showed me what they had actually done. Outstanding service.”

Excellent to deal with
“I contact Cooney Insulations to bring my current loft insulation up to standard using the government’s green home grant. I have to say that they were excellent to deal with throughout, helping me with queries on the grant itself all the way through the installation and final invoice process. The installation itself arranged quickly once the voucher was issued by HMRC at a time that suited me. The Cooney staff arrived on time, taking care to put down dust sheets for the route to the loft. The work was completed with minimum of fuss and they left my home clean and tidy. Highly recommend.”

For over three decades, H&J Energy Solutions has provided insulation services in the UK. They’re a one-stop shop for leaving your home cool, as they offer free surveys and specialise in various insulations.
The material they use is EPS bead insulation, a cost-effective product that’s known for its durability. We don’t mind that they don’t focus on other insulation materials because this one doesn’t require fitting boards—quicker installation!
Apart from installation, they also offer the removal of old insulation. They’ve got it all figured out, and the work we’ve seen has been incredible from start to finish.
One example is the comprehensive service of ensuring that old insulation has been completely cleared off before installing a new one. Sure, that’s how it should be, but not all services are as thorough.
Although they aren’t open daily, their schedule is flexible, as they accommodate clients outside of their regular hours. It’s not like you need to babysit, since their team frequently provides updates.
Efficient in their work
“The H & J team working on our property were excellent ambassadors for the company. They were very efficient in their work, left no mess whatsoever despite the space they were working in. They worked hard to complete the removal of the loft foam and old insulation material, and left the roof space as good as new. I would recommend the H& J team to anyone. Their work and follow up support excellent.”

Reliable and trustworthy
“Harry a surveyor from the company came to the property and assessed the work that was needed.With no pressure he offered insulating to a depth of 300mm (currently only 50 mm) and the pitch, which had no insulation.The work would require 4 days to clear the old material dispose and install the new materials. An excellent team of 3, namely Paul, Joe and the lead team member Derren worked tirelessly for the full 4 days to carry out the work and having very short breaks. The finished product was a well-insulated loft space. I can recommend this company as they are reliable and trustworthy.”

We were pleased with the complete service you’ll receive with GAP Insulation Services. As a Manchester business that focuses on cavity wall and loft insulation, they’ve got extraction and installation covered.
They showcase their over 30 years of experience through their impressive work. The task, from the extraction of old insulation to the installation of a new one, was completed without mess.
They do the job with sustainability in mind, as they specialise in EvoBead insulation, a green material that’s less invasive while saving on energy bills. In addition, it doesn’t require long installation times, which means lower labour costs.
Moreover, the overall cost won’t be too high. Aside from their no-obligation quotations, we were delighted with their prices, which are amongst the most competitive we’ve seen in the area.
No hard feelings for not being as accessible as we’d like (they’re closed on weekends). They’re efficient overall—they came to the site on the dot, quick to respond, and patient in answering even the simplest questions.
Punctual and efficient
“Richard removed our old cavity wall and fitted new. We were given a quote after an initial visit . After we decided to go ahead we changed the area of wall and this was no problem. Richard was punctual and efficient and communication was excellent throughout.”
Karen Wildman, Google Review
So tidy, you wouldn’t know they’ve been there
“Within a week the job was booked, the removal of the cavity wall insulation was done in less than a day and left so tidy you wouldn’t know they had been. Richard is polite, fast and very efficient. All for a very good competitive price. We can highly recommend GAP INSULATION Tony.”

One of the things we appreciate about INSUL8 is their focus on sustainable solutions. They’re not just about doing the job—they continue learning about the newest insulation technologies to better provide energy-efficient strategies.
To illustrate, they offer EPC services that assess your home’s energy efficiency to give you an idea of what to do to lower energy bills. It also avoids having to hire a separate service should you need an assessor.
In addition, thermal imaging surveys are available to accurately see which areas of your house have heat loss. The cherry on top is their cavity wall insulation removal and installation services—overall, they’ve got the situation handled.
Their office is in Nantwich, though, but they serve the North West. Their hours aren’t very flexible, given they’re closed on weekends.
It’s all right, as long as they complete the job. We were delighted to learn that they go to great lengths, as some clients noted the team’s patience and diligence in making sure the task was completed neatly.
Gave a fair and honest opinion
“We asked them for an opinion of the quality and sufficiency of our loft insulation. They gave us a fair and honest opinion – That our current insulation was suitable and that we had no need to make any improvements. They didn’t try to sell us anything that we didn’t need. Would recommend them for an trustworthy honest opinion”
Tim Belfield, Google Review
Always friendly and polite
“Insul8 were fantastic from start to finish hard workers cleaning up after work done plus always friendly and polite when doing the job would recommend them 💯 for work you want doing they keep you updated when they are arriving hardworking guys and no job is any trouble for them in my eyes”

When it comes to cavity walls, CavClear has got it covered… literally. They specialise in insulation and wall ties, ensuring that your walls are safe, secure, and have no structural issues.
You see, they specialise in cavity wall ties and insulation extraction, which can prevent further issues that will compromise the stability of your home. While that’s great and all, their services are a bit limited since their focus isn’t on installations.
It’s fine because when you look at their work, you’ll be delighted, just like us. Their extraction services have been incredibly thorough—so meticulous that the cavity wall doesn’t look like insulation was ever there.
The overall communication has been incredible as well, especially since you can contact them any day of the week. Clients noted that the team was easy to deal with, from the survey to the end of the task.
Plus, they’re a reliable bunch. We gathered from our surveys that they were meticulous and tried to limit disruption as much as possible, which was greatly appreciated by most.
Decent, hardworking, and very knowledgeable
“Delighted with the work done on my house by Cav Clear, repointing the gable end & clearing dodgy insulation out of the cavity wall. They are a decent, hardworking and very knowledgeable team who arrive on time, do everything they can to minimise disruption, clean up after themselves, and always keep you informed of what to expect while the works are underway. I recommend them with confidence, they did a great job for me.”
Ruth O’Connor, Google Review
Worked really hard to deliver
“The team were knowledgeable and worked really hard to deliver on the agreed work. They were keen to keep us informed, hired extra equipment to ensure no dust came into the house and always tidied up. We weren’t sure what to expect but they were very professional and tenacious.”
