Aluminium vs Brick vs uPVC Porch Cost
But how much does a porch extension cost if it's made of different materials?
The illustration below highlights the porch extension cost variations for a 2 m² porch built with uPVC, bricks, or aluminium.
This shows that a uPVC porch costs the least to build, between £1,900 and £2,700, an aluminium porch costs the most, between £2,700 and £3,800, and a brick porch is somewhere in the middle, between £2,200 and £3,500.
uPVC (Unplasticized Polyvinyl Chloride) porches are the most popular choice due to their affordability, followed closely by brick porches which, while a bit more costly, might more closely match the style of the house they're being attached to.
Aluminium and timber porches are more premium choices to consider, especially if you're looking for a more distinctive style.
We cover the pros and cons of each porch extension style that's available later in this guide.

How much does a porch cost if you do everything yourself?
Although it isn’t recommended, you might be interested in taking on a project like this yourself.
If that's the case, you might be wondering what the supply costs are to get everything you need to build a new porch on your existing property.
Let's dive into the list of different supplies that you may need when building a porch yourself (and the prices of each item).
Timber Porch Cost
Timber frames for a porch can range anywhere between £750 and £2,800 depending on the design and size that you are looking for.
A small basic timber frame for a porch will set you back around £750 to £1,000, whereas a large solid oak porch frame costs between £2,300 and £2,800.
Brick Prices
You will need to calculate how many bricks you need to build the structure of a porch extension.
One brick costs between £0.40 and £1.00, and you will likely need between 60 and 70 bricks per m² of porch wall. This assumes you're using standard-sized UK bricks, so you'll need to confirm your requirements when selecting the specific types of bricks you want for your porch build.
Roof Tile Prices
If you are building a porch that requires roof tiles, you will be looking at the cost of between £0.80 and £1.80 per roof tile.
The number of tiles that you need to build a porch roof will depend on the size of the tiles you want to use. A standard-sized roof tile in the UK is 265 mm x 165 mm, which means you'll need between 60 and 70 tiles per m² that needs to be covered.
Flat Roof Rubber Price
The average cost of a flat rubber roof is around £80 per m².
This means that a porch roof that covers a space that's around 3 m² would cost around £240.
Flat rubber porch roofs are a popular choice as they're affordable and easy to install. They're durable too, as they are weather resistant.
Porch Flooring Price
You'll also need to think about the type of flooring you want to be laid in your porch.
Most porches act as a port of entry to the home and are usually laid with either tiled or wood flooring.
The cost of tiled flooring is around £20 per m², and wood flooring prices are about £35 per m².
What Impacts How Much a Porch Costs?
A number of factors can affect the cost of building a porch.
In the subsections below, we've collected together specific factors that might impact the cost of a new porch project.
Size of the Porch
The larger the porch you're looking to have installed, the higher the cost is going to be.
The average porch cost per square metre is around £1,400. This is with standard materials though, and you may find that you're quoted significantly higher than this if you want premium materials or a specific aesthetic.
With this in mind, you can see how the price can drastically rise if you choose to build a larger porch.
Number of Porch Windows
Porch window prices are usually between £300 and £1,000.
The upper end of this range is reserved mainly for the most premium options. There are various options that are priced between £300 and £500 which will be suitable for most average installations, although it's also worth investing in double-glazed windows to help with energy efficiency and home comfort.
The more windows, the higher the total porch cost.
Porch Roof Style
The two most popular styles of roofing for a porch are a tiled pitched roof and a rubber flat roof.
Here's a look at how much you can expect to pay for different roof styles:
- Pitched Roof - £30 to £65 per m²
- Gable End Pitched Roof - £30 to £65 per m²
- Flat Roof - £35 to £70 per m²
- Double Hipped to Wall - £50 to £100 per m²
- Double Hipped to Ridge - £25 to £60 per m²
- Single Hipped - £30 to £65 per m²
Porch Types
The types of porch will also lead to variations in the price you're quoted.
For example, if you would like a lean-to porch extension, you can expect a uPVC porch cost to be around £2,500 - whereas a flat gable roof porch costs roughly £3,500.
I have been quoted £260 for a porch light fitting, and I have supplied the light. Is this too much?
Types of Porch
There are various types of porches - and each one comes with its own set of advantages and disadvantages.
Below are the different types of porches that you can add to your existing home and the pros and cons of each one.
uPVC Porch
uPVC porches are a traditional style of porch that uses uPVC as the primary material. Due to the ease of customisation and their affordability, uPVC porches are a very popular choice in the UK.
Pros
- ✔ Completely weather-resistant
- ✔ Low maintenance
- ✔ Good value for money
Cons
- ✖ Lack of character
Lean-To Porch
A lean-to porch, as the name might suggest, is a type of structure that looks like it's leaning onto the side of a building.
This is a popular type of porch, which is a straightforward addition to a property's exterior.
Pros
- ✔ Blends in well to most homes
- ✔ Simple and easy to build
- ✔ Can easily be removed
- ✔ Perfect for small spaces

- ✔ Matches the aesthetic of most UK homes
Cons
- ✖ Can be more expensive than uPVC porches
- ✖ Takes longer to build due to the extra effort involved in bricklaying

Pros
- ✔ Extremely tough and strong
- ✔ Lightweight and flexible

Cons
- ✖ Quite expensive

What's Involved in Building a New Porch?
Building a porch can be a difficult job, and it’s important that it is done safely, precisely, and in line with UK building regulations in order to achieve the best results.
This type of extension requires a lot of specific knowledge in terms of materials, design, and execution. With this in mind, building a porch is a job that is best left to experienced professionals and not one recommended as a DIY project.
Due to the complexity of the work, it's not just about getting the best price to fit your porch budget, but also about hiring the right people. That's why it's recommended to search via MyJobQuote to find porch specialists in your area and receive at least three free quotes, without having to commit unless you're entirely confident.
So, what's actually involved in building a porch? Here's an overview of the basic process:
Before the Job Starts
- Site Assessment — Your builders will begin by assessing the area where your new porch will be built. They'll look at the ground, see if there's an existing base that's suitable for use, and consider if any additional drainage will be required or moved.
During the Job
- Laying Foundations — The area where your porch will sit is dug out ready to create the foundations. Concrete is poured, and a damp-proof course is added to prevent any moisture issues.
- Creating the Subfloor — A second layer of concrete is poured on top of the damp-proof course and left to set, forming the subfloor.
- Building the Walls — Your builder will then start work on the walls once the subfloor has set. If you are having brick walls, these are built up while allowing sufficient window space free.
- Installing the Roof — Once the walls are in place, the porch roof is installed. Depending on the porch design, this can involve timber rafters, support beams or a flat roof frame being added. At this point gutters and downpipes can be added to help disperse rainwater away from the building.
- Windows, Doors, and Interior Finishes — Finally, porch windows and front door are installed, and the interior is plastered. Skirting boards, flooring, and any necessary electrical work are also fitted.
After the Job
- Final Checks — The builder will check the completed porch to ensure your new porch extension is fully functional, with fixtures and fittings working, while ensuring the end project will sufficiently meet building regulations approval.
Checklist: Hiring a Porch Builder in the UK
When you're looking to build a new porch extension, it's important to understand the building costs involved and any questions you need to ask when hiring someone to carry out the work. As such, consider the following points when searching for the right person for the job:
- Have they completed a similar porch project recently? Ask to see the builder’s most recent porch design they've been involved in constructing, along with any other related jobs.
- Do they have a portfolio of their work? Along with their most recent porch build, this will give you an up-to-date picture of their current level of expertise and previous projects.
- Have you checked for positive reviews? Search for the building company online, check their MyJobQuote profile and social media for reviews and past client feedback.
- Are they able to self-certify? This helps ensure the builder will complete the work in accordance with building regulations. Also, check if they will handle the necessary paperwork and approvals.
- Will they discuss the porch project in detail? Hire a company that will work with you on all areas of your new porch design until you’re completely happy with the proposal and final porch cost.
- Are they able to accommodate custom designs? Whether it's double-glazed windows, decorative glass, brick walls instead of uPVC, or custom features, ensure the building costs include any special requests.
- Have you requested more than one quote? It is always recommended to source at least three separate quotes, which can help provide a more accurate idea of the average porch cost. MyJobQuote can connect you with local builders without any commitment to hire.
- Have you received a detailed cost breakdown? This should include each aspect of the porch cost, from the front door to labour and materials, so there are no hidden fees.
- Do they have insurance and guarantees? Builders should have public liability insurance in case of an accident or injury during the porch project. Check what guarantees are offered before, during, and after the build.
