How Much Is A Sun Tunnel?

The cost of installing a sun tunnel on average is between £520 and £710, with the higher end being for a rigid tunnel on a flat roof rather than a pitched roof.

A sun tunnel is an innovative yet cost-effective way of allowing and promoting natural light in your home. Designed especially for those areas of the house that can’t reap the benefits of natural sunlight.

A sun tunnel works by channelling natural sunlight through a tube from your roof down to your ceiling, using reflective materials, and a diffuser at the end to disperse the light covering as much of the room as possible.

Getting enough natural sunlight in your home can be a tricky task, especially for those of us with smaller homes and windows, or who live in terraced houses, where opportunities for getting enough sunlight are scarce.

Getting enough natural light in your home will bring a host of benefits with it, such as health and well-being. Getting enough natural sunlight throughout the day is important for your health, and a naturally lit home can also lift up your spirits and make it a place you want to spend time in.

Natural daylight can make all the difference in darker homes and will add a lot of energy. You will notice the difference between the sun tunnel and your light fixtures or a lamp. Speaking of which, you could see a difference in your energy bills. By installing a sun tunnel, you are less inclined to turn on lights during daytime hours.

Now a sun tunnel may be something you have never thought of before or even heard of, That’s why we aim to give you as much information as possible in this guide. Your main concerns are going to be what is right for you and your home, and obviously the costs, including that of the sun tunnel itself and any additional materials, and the cost of hiring a specialist to come and install it.

Things to Consider When Installing a Sun Tunnel

You will also need to be aware that there are a few different styles and variations of sun tunnels to choose from. First of all, is the type of tunnel you want, or will need – you have the choice of a rigid or flexible tunnel.

  • A rigid sun tunnel is a straight tube running from the roof straight through the loft and down to the ceiling. Because the light travels in a single motion, you will gain the most light to your room with this option.
  • A flexible tunnel will be used to navigate or angle around objects in your loft space in order to reach the ceiling from the roof. Because of the angling of the tunnel, this reduces the amount of light that enters the room.

Installing a flexible sun tunnel is best for shorter distances, so as to reduce the number of angles and to keep as much of the natural light as possible.

You may also need to decide on the type of panel for the outer roof you want, you can choose from either a dome panel or a flat panel. A dome panel will be much more effective at capturing the light, as light actually refracts once it hits a clear dome, meaning much more natural light will be dispersed into the room.

A flat panel is probably a bit more aesthetically pleasing, depending on your tastes, however, a flat surface will reflect the light rather than capture it. Meaning you won’t get the full benefit.

The diameter of the tube will also be important for light distribution, consider 10 inches for smaller rooms or hallways and up 14 inches for larger rooms such as a living room or kitchen.

For this job, we would recommend hiring a specialist, more specifically a roofer or someone with relevant experience in roofing. This isn’t a job we would recommend for even experienced DIY enthusiasts.

Your hired specialist must be knowledgeable and experienced in fitting fixtures to roofing, especially when sealing up the fixture to ensure there are no signs for potential leakage in the future.

Sun Tunnel vs Skylight

Sun tunnels and Velux window skylights are pretty much designed to do the same thing - introduce natural light into your home.

Sun Tunnel

Pros

  • More affordable option - Less expensive than installing a skylight, requiring a lower budget for materials and labour fees.
  • Ideal for small spaces - Suitable for areas with less space for installation, such as bathrooms and hallways.
  • Quicker installation - The installation also isn't as invasive on homelife, due to requiring a smaller roof opening.
  • Energy efficient - Due to the small area, any potential heat loss is minimal.

Cons

  • No outside view – installed purely for creating light and aesthetics.
  • No ventilation – sun tunnel designs can't be opened for airflow.

Skylight

Pros

  • Creates more light - Ideal for larger areas, helping to make a room brighter.
  • Provides ventilation - Skylight windows can often be opened to let in air.

Cons

  • More expensive - Higher material costs and additional labour fees.
  • Complex installation - Can potentially require structural work, increasing cost.
  • Higher maintenance - Including regular cleaning and general maintenance.

Planning Permission and Building Regulations

In the majority of cases installing a sun tunnel doesn't require planning permission, in particular if you own the property and the work is being carried out on a residential roof.

However, this may not be the case if your home is in a conservation area, a listed building, or has specific restrictions in place. In which case, it is always best to check with your local planning authority first, and if you do need to formally apply then this can cost between £206 and £528.

As for building regulations, there are certain rules and requirements your sun tunnel installation must adhere to. These are in place to help ensure the sun tunnel is properly sealed to prevent leaks, insulated to avoid heat loss and will pass any safely checks.

Hiring an experienced professional is recommended to make sure any procedures and regulations are followed correctly.

Can You Install a Sun Tunnel Yourself?

Unfortunately, this job is not something we would recommend taking on yourself as a DIY project. Unless you have the appropriate roofing experience, taking on this job will likely leave you with more costs than you had originally planned.

The part of the job that includes removing or replacing roof tiles, attaching the panel and sealing it up, is a tricky task even for most experienced roofing experts. As well as the potential damage to the roofing, leading to expensive roof repair costs if the panel is not sealed properly, this will cause leaks and lead to water damage all the way through to your ceiling.

Of course, there is also the safety aspect of working on a roof, if you don’t have the appropriate equipment and experience then you should not tackle this job. If you aren’t comfortable working at heights, then this job definitely isn’t for you.

Checklist for Installing a Sun Tunnel

  • Sun tunnels come in both flexible and rigid tubes - ensure you choose the right one for your home.
  • A dome panel will capture more light than a flat panel, which can reflect some of the light.
  • A sun tunnel will reduce the use of electrical lighting, thus reducing energy costs.
  • Ensure your hired tradesman is has sufficient experience in roofing, especially sealing panels preventing leaks.
