A complete guide to installing a carport

Keeping your vehicle in top condition is a priority. Choosing to install a carport is a popular way to protect your vehicle from the elements. If you are thinking about installing a carport, read this useful guide to learn about everything you can expect when you decide to have a new carport installed.

What is involved in installing your carport?

If you haven’t got a garage, a carport is a quick, affordable and easy way to create a covered parking area for your vehicle. With a simple design that only requires a few materials to erect, carports are a convenient and hassle-free way to shield your vehicle from weather damage.

With your vehicle protected from the sun, ice, snow and rain, your carport is immediately ready for use in the morning, meaning that you no longer have to waste precious time scraping the car free from ice and snow during the cold winter months.

Fitted at a lower cost than a garage, with no possibility of complicated planning permission, carports are a simple and straightforward storage solution that will also increase the value of your home. They are available in wood or metal.

What should you expect if you are planning to install a carport?

If you are having a carport fitted, you should confirm the actual length of the frame when you order. Once fitted, the length of the carport frame is always 30.5 cm shorter than the length of the roof, so it is useful to know the finished length from the outset.

Before the installers arrive, you will need to make sure that the area is clear and suitable for installation. If you do not already have a concrete base in place, you may decide to have one laid so that your vehicle is parked on a flat surface.

With the ground prepared, the posts will be set in concrete at least 121cm deep and left to harden overnight. One side of the posts will be slightly higher than the other so that rainwater can drain away. The higher posts should be those positioned nearest your home to keep water away from your home’s foundations.

Next, the rest of the carport’s structure will be built and the roof fitted. For all-weather protection, the carport roof will be finished with a waterproof seal.

Once your carport is fitted, you may decide to employ a decorator or builder to finish the exterior in a more customised way, or a gardener to refresh the area around the carport.

Carports can be built in wood or metal. When deciding which material to choose, it is useful to consider: which material will best match the exterior of your home, as well as the type of weather that the carport will need to withstand. Robust and long-lasting, galvanised metal or pressure-treated wood are the most popular types of materials used to create carports.

If your carport will endure high levels of rain at particular times of the year, it will be crucial that the drainage system fitted will be able to drain away enough water effectively and avoid becoming blocked. If there will be heavy snowfall during the winter, then your carport’s design must be strong enough to cope with the extra weight of the snow. A high-quality weather-proof finish is equally important too.

The type of material that you choose as well as special customisations, will affect the overall cost of the job. Additionally, you may want to have a concrete base laid to ensure that your vehicle is parked on a level surface.

Most carports do have a concrete foundation laid before the carport structure is fitted, so this is easy to organise, but will increase your final costs. If you do not want to concrete over the area, there are many homeowners with carports over grassed areas, so check with your installation company if you are unsure which surface you would like.

It is tempting to opt for a sizeable carport with plenty of room, however, do bear in mind that a larger structure will cost more. Adding space for an additional car can increase your costs by as much as £650, so think carefully about what you really need.

Finally, check the area that you would like to use for the carport carefully. If digging causes damage to underlying pipework, you will end up having to fork out extra money for repairs.

Waste Removal


You do not need planning permission to install a carport unless:
- The carport is taller than 4m.
- The eaves height of the carport is higher than 2.5m and within 2m of the property boundary.

These are both highly unlikely, so it is safe to say that you do not need planning permission to install a carport.
It costs around £2500 - £3500 to build a standard carport, although you do need to factor in things like the type of material that you choose to use. If you want to enlarge the standard space to create a bigger carport, expect to spend around an extra £650 or more per car. Additionally, you will need to include the increased cost to elements like the concrete base, as well as considering the actual measurements of the finished carport.
Carports are relatively simple to fit and most will be fitted within a day. If you have opted for a larger structure or need to have a concrete pad laid too, expect your carport to be installed within two days.
The size of the double carport will depend on how big each of your cars are, plus you will need to consider the extra room that you will need to get in and out of each car comfortably.

Ideally, a carport for two mid-small cars will be 20 x 21 feet. If one or both cars are on the bigger side then 22 x 21 feet or even 24 x 21 feet will give you enough room. Speak to your carport installer before making any decisions, because they will know the best dimensions for the particular style of carport that you would like, as well as the type of cars that you have.

For double carports you will also need to ensure that access in and out of the carport is sufficient for either parking space. Again, your installer can help you to choose the most appropriate design for your needs and make the most out of the space that you have to work with.
