A Look at Front Porch Prices in the UK

Are you looking to construct a front porch to your property and are wondering how much it will cost?

Whether you are considering an enclosed porch or simply a canopy over the front door, you have come to the right place.

A porch is an ideal place to store jackets, shoes, dog leads and other items, freeing up space inside the property. You’ll also have a roof over your head to keep you dry when it’s pouring with rain.

It is also a very economical way to add practical floor space to your home.

But what is the going rate for a fully installed porch?

How Much Do You Think a Small Porch Will Cost?

This may sound like a strange question. After all, you came to this page to see how much porches cost.

However, we are doing research into how much homeowners think certain home improvement projects will cost.

Do You Need Planning Permission? What About Building Regs?

To calculate the cost of a new fully installed porch, you first need to determine if planning permission is required.

If the dwelling is a listed building then you will almost certainly require planning permission. The cost of this varies from council to council, but you should be able to find prices online.

If the property isn’t a listed building, then the following will most likely apply.

You do not need planning if:

  • the total floor area does not exceed 3 square metres
  • the height does not exceed 3 metres
  • no part of the porch is within 2 metres of the boundary, public path or road

The Planning Portal (which is a website we suggest you read through) also states the following:

Building a porch at ground level and under 3 square metres in floor area is normally exempt from the need for building regulation approval.

This is provided that glazing and any fixed electrical installations comply with the appropriate sections of building regulations.

For a porch to be exempt from building regulations approval:

  • the front entrance door between the existing house and the new porch must remain in place
  • if the house has ramped or level access for disabled people, the porch must not adversely affect access.

In other words; to be exempt from building regulations approval, you can’t remove the existing door and have an open plan porch.

If you remove it, then the porch must comply with the myriad of regulations, including fire safety and insulation.

What Options Do I Have?

There are hundreds of different styles to choose from.

From all Upvc and glass, including glass roof panels, to aluminium framed and also a more traditional brick porch with a front door and side window.

The prices displayed further down this page will be for:

  • 3 sq metres of floor space
  • brickwork
  • one composite front door
  • one or two double glazed windows
  • tiled roof with gutter system
  • plaster work and one light inside

The prices below exclude painting, decorating and floor coverings such as carpets or wooden laminate etc. Everyone has different tastes and budgets so we will exclude those items.

Foundations, concrete floor and brick work – £1000

One door and one or two windows – £1400 (see separate prices for doors/windows here)

Plastering work, sills and skirting boards – £400

Electrician and parts 2 hours – £150

Timber roof, tiled and guttering – £1200

Waste disposal – £75

Total cost for 3 square metres is £4225 or £1400 per square metre

Don’t forget; we haven’t included the cost of flooring, curtains or blinds which could bump up the price to around £1600+ per square metre.

Also, our guide price of around £1400 per square metre assumes you have the work carried out by a local trades-person.

If you instruct a larger company, such as a national double glazing firm or conservatory company to do the work, then expect to pay more.

This is because many of these firms have:

  • sales staff that are paid a commission between 10% and 15% of the total cost
  • office staff, call centre staff and layers of middle management
  • in some cases; shareholders
  • profit expectations

Our suggested price of around £1400 per square metre could easily rise to £2000 or even higher.

Does Location Affect the Price?


Our prices assume the work is carried out to a property in the south of the UK but outside of London. This is the area we have the most experience in.

You can expect London to be the most expensive area and the north of the UK to be cheaper.

What Are Others Saying About Front Porch Prices?

2pm Architects suggests a price of around £1250 per square metre for extensions finished to a basic specification and around £1850 for a standard finish. This may seem high but the prices include some fees that are not applicable to porches such as engineer fees, planning and building control etc.

Mumsnet is a very popular forum where homeowners discuss many hundreds of different topics. This forum page has several commentators and most of them suggest a price of at least £1000 per square metre, the forum page is 6 years old so you’ll need to take into account inflation and price increases.

DIYnot is another forum where homeowners post questions and professional and keen DIYers answer them. This forum thread has a question about porch prices and several answers including from builders who have experience in constructing porches. £5000 for a professionally installed porch seems to be the accepted rate.

Where Can You Save Money?

Because porches are so practical and are located at the front of the property, we don’t recommend scrimping and saving by using poor quality materials or installation techniques.

That said, there are some things to consider:

  • a felted flat roof is cheaper than a tiled roof but doesn’t look nearly as appealing
  • a one sided tiled roof (a lean-to) is cheaper than a multi-faceted roof
  • double glazing windows and composite doors can be expensive but there are many different products on the market, so it’s worth looking around

Is There a Cheaper Alternative to a New Porch?

If a fully enclosed porch isn’t what you’re looking for then you could consider a canopy.

These offer protection from the rain but are otherwise open and are essentially a hood over the front door.

Canopies can be made from timber and have a tiled roof or they can be manufactured from plastic or fibreglass.

We are huge fans of classic timber porch canopies as they’re affordable, can be covered with any type of roof tile and painted to match the doors and windows.

A good starting point is the kits supplied by Chiltern Timbers.

Small timber canopy kit – £350

Paint – £50

Felt and tiles – £150

Labour, one day – £300

Total cost – £850

Will a New Porch Increase My Home’s Value?

If you live in a home where the front door opens directly into the living room or there is limited space downstairs, then there’s a good case for building a porch.

You may then get back what you paid when you come to sell the house.

Design a porch within the constraints of the permitted development rules and you won’t need planning permission either, which will save you money.
