If you are looking to improve the comfort and energy efficiency of your conservatory, you may be exploring insulation options. However, one question often arises: Should you go for professional conservatory insulation, or do you try to cut costs and take the DIY route?   

In this blog, we’ll take a look at the pros and cons of both approaches, helping you make a decision based on your individual needs and budget. 

Insulating your conservatory can make a real difference to the way you use your space. It opens up options on what you use the space for and allows you to have access all year. If you are looking to reduce your energy bills, increase comfort, or simply make the space more functional, then insulation is the answer.

Here, we look into the two main options available: DIY and professional insulation. 


The Benefits of DIY insulation 

  1. Cost-effective: One of the most significant advantages of DIY conservatory insulation is the potential cost savings. By buying the materials and doing the work yourself, you can often save a large amount compared to hiring professionals.
  2. Flexibility: DIY projects offer the flexibility to work at your own pace and convenience. You can complete the insulation in stages, fitting it around your schedule and carrying out the work when you can. 
  3. Satisfaction: Completing a DIY project can provide a great sense of accomplishment. Knowing that you’ve insulated your conservatory yourself can be rewarding. 

Drawbacks of DIY insulation 

  1. Time-consuming: Insulating a conservatory can be a time-consuming process, particularly if you have to learn lots of new skills. Make sure you are prepared and aware of the time it will take to complete the project – setting realistic timeframes. It will require careful planning, preparation, and then patience to complete the actual work.
  2. Skill level: Effective insulation requires a certain level of skill and knowledge. Mistakes can lead to faults in the insulation and the way it performs, which ultimately reduces the benefits that come from it.
  3. Limited warranty: Most DIY materials come with limited or no warranty. If something goes wrong, you’ll need to fix it yourself, which can add to the cost and time spent on maintenance. 

DIY conservatory roof insulation kits 

For those opting for DIY, you can explore conservatory roof insulation kits that have gained popularity among homeowners. These kits are convenient as they usually come with all the necessary materials for the job, including insulation panels, adhesives, and tapes. 

One example of such a kit is the Ecohome Insulation Kit, which includes reflective insulation panels and comprehensive installation instructions. These kits are designed to be user-friendly, making them accessible even for those without extensive DIY experience. 

It’s crucial to follow the provided step-by-step instructions meticulously to ensure the insulation is effective. Here’s an example of a DIY conservatory roof insulation kit with detailed instructions: Ecohome Insulation Kit. 

By choosing a reliable kit and adhering to the instructions, homeowners can achieve effective insulation results while saving on installation costs. 

Professional Insulation 

Advantages of having insulation fitted professionally: 

  1. Quality and expertise: Professional installers bring a range of experience and expertise to the job. They are trained to handle different insulation materials and techniques, ensuring a high-quality finish. This expertise translates into better thermal performance and durability of the insulation. For instance, professionals know how to manage challenging aspects like ensuring airtight seals and avoiding thermal bridging, which can hugely impact the efficiency of the insulation.
  2. Warranty and guarantee: One of the significant benefits of opting for professional insulation services is the warranty or guarantee that often comes with the service. This means that if any issues arise, such as insulation failure or unexpected gaps, the installers will address these problems at no additional cost. This assurance can save homeowners from future repair expenses and provide peace of mind.
  3. Time-saving: Installing insulation can be a time-consuming task, especially for those who are not familiar with the process. Professionals can complete the installation much more quickly, giving homeowners the opportunity to enjoy the benefits of an insulated conservatory sooner. If you already have a busy household, this service may suit you.
  4. Safety: Professional installers are equipped with the necessary safety gear and knowledge to complete the insulation process in a safe way. This includes the use of ladders, handling of insulation materials, and working in potentially confined spaces. By hiring professionals, homeowners can reduce the risk of accidents or injuries that might happen during a DIY installation.
  5. Consistency and reliability: With professional installation, you are more likely to achieve consistent results across the entire conservatory. Professionals follow industry standards and best practices, which makes sure that the insulation is installed correctly throughout the space. This consistency can lead to better overall performance and energy savings. 

Drawbacks of professional insulation 

  1. Cost: The most obvious disadvantage of professional insulation is the cost. Hiring professionals is generally more expensive than undertaking a DIY project because it includes labour costs and possibly higher-quality materials. However, it’s essential to consider this expense as an investment in long-term energy savings and comfort.
  2. Scheduling: Depending on the availability of the insulation professionals, you might need to schedule the installation well in advance. This can be less flexible compared to the DIY route, where you can choose your timeline. Homeowners may need to work to the schedules of the installers, which could cause some inconvenience.

Professional insulation tends to offer superior quality and longevity compared to DIY solutions. The expertise and precision that professionals bring to the job mean that the insulation is more likely to perform optimally over time. This can result in better temperature regulation, lower energy bills, and fewer maintenance issues in the long run. Some insulation processes, such as Cosy Panels, can be installed within 24 hours, giving you a fast and efficient service.


DIY vs. professional installation comparison


  • DIY: Generally cheaper as you only pay for materials – this can make it an attractive option for budget-conscious homeowners. 
  • Professional: More expensive due to labour costs but may offer better value over time due to superior quality and longevity. The upfront cost is higher, but the long-term benefits can outweigh this initial expense. 


  • DIY: Limited or no warranty on materials, meaning any repairs or replacements will be out of pocket. 
  • Professional: Often includes warranties and guarantees, covering both materials and workmanship. This provides peace of mind and protection against future issues. 


  • DIY: The quality of the installation depends on your skill level and how carefully you follow the instructions. Mistakes can compromise the effectiveness and efficiency of the insulation. 
  • Professional: High-quality installation by experienced professionals gives optimal performance. Professionals have the expertise to handle various materials and techniques, giving a faultless finish. 


  • DIY: May need repairs or adjustments over time if not installed correctly. Poor installation can lead to reduced effectiveness and a shorter lifespan for the insulation. 
  • Professional: Professional installations are designed to last longer, providing better durability and performance. The higher quality of workmanship means fewer issues and longer-lasting benefits. 


Which is the best insulation for you? 

Deciding between professional and DIY conservatory insulation depends on your specific needs, budget, and skills. If you’re looking for a cost-effective solution and are confident in your DIY abilities, the DIY route might be suitable.
