Carport cost guide
by
Checkatrade

A purpose-built carport is a great option if you want secure off-street parking without the expense of constructing a garage. Carport costs are much lower than brick-built garages and can add substantial value to your property too.

In this carport cost guide, we describe the average costs to build a carport and break down the steps to follow.

What is a carport?

Carports are permanent structures that provide protection for your vehicle outside. They can often be confused for garages, but there are some crucial differences:

  • Carports can be freestanding or lean against your property.
  • Garages are fully enclosed structures with four walls, carports are open structures, with one, two, or sometimes no walls at all.
  • Most carports are built on top of sold concrete bases but can be built on top of grass.
  • Carports are built around posts sunk and set over 1 metre into the ground.
  • Carports need a roof with drainage system to safely take away rainwater.
  • Carport roofs can be flat or pitched.

One important difference is that the cost of building a carport is substantially lower than the cost to build a garage. They are much simpler to build, which makes them quicker to construct.

Lower labour and materials costs mean the cost of building a carport can be around a quarter of that of a brick-built garage.

Do I need planning permission for a carport?

Unlike garages, you will 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.

This is one of the reasons why the cost to build a carport is typically much less than that of building a garage.

How are carports constructed?

Carports come in various combinations of materials and designs, all of which will affect the price you pay to build a carport.

Carport base

Most carports are built on top of a solid level concrete base. The cost of laying a solid concrete base isn’t included in our carport cost guide and should be factored in to your plans.

Carports can be built on top of grass but repeated use of the carport will wear away the grass quickly unless you use some form of support.

Wooden carports

Wooden carports are built from treated timbers that are protected from corrosion from wind and rain. Wooden carports are cheaper to build than metal carports but may not last as long.

Metal carport cost

Metal carports

Metal carports are built from galvanised metal. They’re hardwearing and corrosion resistant and should last for many years.

Carport roof

You can choose between a simple flat roof or a pitched roof. Flat roofs are often made from sheets of plastic and are cheaper to construct. Pitched roofs are more complex to build, but are longer lasting and many prefer their traditional appearance. All carports will need a drainage system to take away rainwater and snow.

The height of your carport will depend on the type of vehicle you will store in it. If you have a camper van or high-sided vehicle, for example, then you will need a carport with a higher roof, which can increase carport costs.

Average carport installation costs

The average costs are based on a single carport and will vary according to a range of factors described below.

A single carport should cost between £2000 – £4000 to build, with an average carport costing £3000.

Cost providedUnitCost range (low - high)Average cost
Install a single carportJob£2000 - £4000£3000
Install a double carportJob£3500 - £6500£5000
Lay a 12 ft x 14 ft concrete baseJob£1800 - £3000£2400

Double carports are more expensive and will cost around £5000 to install.

These costs do not include the cost to lay a concrete floor or the cost to hook up mains services, such as electricity, gas or water.

If you need to have a concrete base installed expect to pay around £2400 to lay a 12’ x 14’ concrete base.

How long will it take to install a carport?

It should take a team of experienced tradespeople between 2 – 3 days to install your new carport.

The time it takes to build a carport depends on the factors such as its size, materials and access to the property. Your carport may take longer to construct if you need to lay a concrete base.

Other costs that could affect carport prices

The total carport price for installation will be affected by several factors, such as:

  • Demolition and removal of any existing structure
  • Size of the carport you are building
  • Preparation of the area required
  • Whether you need to lay a concrete floor
  • Rubbish or waste removal
  • The costs of painting and finishing your new carport
  • If you are building on top of pipework or drains
  • Location of your property
  • Access to your property

Can I build a carport myself?

While you can purchase pre-fabricated carport kits, they can be complicated to construct. Building a carport is a challenge and while it can be undertaken by an amateur, we recommend using a professional for a long-lasting carport that adds value to your property.
