How much do Builder services cost?

How much do Builders cost? Prices for Builders in 2026 can fluctuate relying on the sort of work that you need to have carried out in your residence.

Are you planning to erect a new house or structure? If yes, then you’d probably want to know just how much it’ll take to get the project over the line to help you set a budget and start to plan. Building a new house is requires huge financial investment and as a result, there’s the need to carry out your due diligence before you proceed. In this post, we’re going to give you an insight into the prices charged by builders to erect a new home or structure.

First and foremost, like every other home project, the price charged by builders to construct a new house or structure depends on a wide range of factors. These factors include the size, location, accessibility as well as qualifications of the builders you wish to employ just to mention a few. For instance, you’d expect the cost of building two-storey in London to be a lot more expensive than the price of a one-story building in Scotland. However, we’ll try our best to give you an idea of the price range you can expect to incur to complete your project.
In general, a builder will charge within the range of £10 to about £15 per hour on the average. For small building projects which includes wall and foundations repairs, a builder will typically charge about £11 per hour. However, the price charge will depend on the extent of the job due to the fact that simple tasks such as repointing only costs about £10 per hour, while laying new foundations can cost up to £15 per hour.

The table shows the types of work that Builders typically do and the average cost range of these tasks. Some tasks take longer to finish than others so prices do fluctuate by job.

Builder FAQs

do you need planning permission for a porch?

There are so many benefits that comes with building a porch in your home premises. It’s an extra space where a lot can be achieved such as drying a dripping wet dog, taking off your dirty shoes or boot and lots more. So if you’re considering to construct a porch, it’s definitely going to be a wise decision. However, before you get started, there’s a need to determine if you’ll need planning permission for a porch. It’s important to take note that planning laws are dynamic and can be updated at any point, so be sure only to use trusted sources only as your guide. If you’re the homeowner or landlord, it’s entirely your responsibility to obtain the right approval for any development project you wish to carry out within your premises.

A Porch can not be termed as an extension and neither is it a conservatory, they’re basically built to the home’s front covering the main entrance using a stone base or a brick. As a result, a porch does not need planning permission due to the fact that it’s covered by the permitted development rights if the specific guidelines for porches are complied with. Below are the instances where you WILL need planning permission for a porch.

✓ If the floor space is more than 3sqm (the wall inclusive).

✓ The highest point has a height of more than 3 metres.

✓ If the porch is situated within 2 metres of a boundary directly facing on to the road.

You may need planning permission if the house is a listed building, designated area or falls under an Article 4 Direction.

In order to build a porch without planning permission, you need to consider all the criteria stated above. You can also visit the Planning Portal website to get more detailed information before getting started.

how does loft insulation work?

A lot of an uninsulated property’s heat is lost through the roof and that’s even more alarming, when you realize this figure is up to a quarter of the total heat of the house. Hence, the tremendous importance of preventing this heat loss through loft insulation which will go a long way to help you against spending unnecessary thousands of pounds on heating bill as well as energy loss.

 

Loft insulation is an effective method to achieve the desired result, however the question is, how exactly does it work? Well, it’s time to find out!

 

Using either a fireplace or central heating to heat up your home, a large quantity of that heat would be lost through the roof of your home. Generally, heat rises and when it does, there’s simply no way to prevent it - it’s just science. Escaping by both the conduction and convection methods via your roof, the heat escaping through your ceiling, into the loft space and out into the open air outside can only be significantly reduced by laying loft insulation.

 

Generally, the added layer of insulation works by trapping the heat inside the room below the loft so as to enable the air within your house to stay warmer for longer. What’s more? The layer of insulation also keeps cold air from the outside from entering your home. As a result, you don’t have to heat your home as much in order to achieve the same temperature for each individual room. Over time, just by doing this you can potentially save hundreds pounds. Getting it installed in your home may actually seem a bit expensive at first, but it’s something that’ll eventually pay off.

Is external wall insulation safe?

With the numerous benefits that comes with the installation of an external wall insulation in a building, it’s also important to find out whether it’s also safe before proceeding to fit one in your home. Firstly, to ensure that external wall insulation systems are safe, they must be BBA approved, which means they’ve been subjected to a thorough testing by the British Board of Agrement and therefore, suitable for use in UK homes.

Given the fact that cladding materials have recently generated a lot of debate and negative press about how reliable some particular materials are, questions are being asked of the safety and reliability of external wall insulation. However we must clarify that, although external wall insulation can be classified under cladding, it is very different to rainscreen cladding - which caused the Grenfell fire tragedy.

External wall insulation is completely safe. However, when it comes to fire, the safety of your system depends largely on the insulation type in question. The safest type of insulation you can have installed is the Rockwool insulation boards which are rated as Euroclass A1 non-combustible. The board is specially designed in such a way that it contains fire - preventing it from reaching the other areas of the building. They also do not produce harmful emission or smoke when impacted by fire.

Meanwhile, the Wood Fibre, is also a great insulation which is known to char and not burn. Contrary to many beliefs, it actually burns slowly creating this charring effect which produces an oxygen barrier that helps reduce the spread of fire.

To make your system safer, you can also make use of Fibreglass Mesh for reinforcement. It helps to improve the strength of the tensile which promotes the security of the boards attached to the wall.

how much loft insulation do I need?

Over the years, more and more home and property owners are beginning to realize the huge benefits that can be derived from loft insulation being a worthwhile investment. It’s quite worrisome the way in which energy bills have soared over the past 10 years and loft insulation is a considerable affordable energy efficiency measure that can go a long way to help increase your home’s energy savings.

 

As far back as the 1980’s, the standard when it comes to insulation thickness was 25 mm to 50 mm which was, at the time, considered to be sufficient. However, building regulations have changed the norm that now states that a new build needs to possess 270 mm of insulation in the loft in order to achieve the required u-value of less than 0.16/m2k based on the standard rock wool or sheep wool insulation.

 

Generally with loft insulation, there’s a law of depreciating returns which implies that the first couple of insulation centimetres will save you many times the cost of the installation, however an extra layer or centimetre is going to add less value to the point where it’ll no longer be wise or worthwhile to add any further centimetre. Therefore, with cheaper energy prices 30 years back, that additional couple of centimetres was not just worthwhile, but with the recent alarming rises in costs of fuel, that additional £10 savings per year has all of sudden changed to £30 which makes it become a lot more attractive.

 

If you already have 270 mm of loft insulation, regardless of the material you’re looking to add you’re most likely not going to benefit from a top up. The cost of the materials and installation will definitely be too high for the couple of pounds it’ll save you per year.

Can builders work on a Sunday?

General construction work should be restricted to the following hours: Monday to Friday 8am to 6pm. Saturdays 8am to 1pm. Most councils advice that noisy work is prohibited on Sundays and bank holidays but you should check with your local council to confirm this.

Does external wall insulation add value to your home?

The answer is yes! Houses whose external walls have been insulated are more valuable than their uninsulated counterparts. And not only does it add to the value of a home, but also significantly reduces the amount of electricity consumption. This is a major turn on for potential investors which implies a greater demand and ultimately, a higher price. The real estate market is a very dynamic one which can be hard to predict at any particular time. The frequent changes in price are usually down to factors beyond the owners’ control, but if you’re looking to put up your house for sale in the near future, it would be a wise decision to consider ways in which you can increase its value. While renovating each room can be on the expensive side, a great solution would be insulate the external walls.

An insulated house is one that is well secured against the harmful impact of extremely high or low temperature, humidity and other atmospheric factors. Hence, the reason why a house with external wall insulation has a greater value which you would not want to miss out on. What’s more? You’ll get a great thermal insulation with the top notch materials like foamed polystyrene, high quality renders, mineral wool or polyurethane.

With an external wall insulation, you know the transaction will always be favourable on both ends. You get to smile to the bank, while the buyer also gets to enjoy great value for every penny spent. To employ the services of a reliable external wall insulation expert, simply conduct an in depth research from family and friends, online and other sources. Go through their online reviews and ask questions to become more familiar with the process and its value-adding potentials.

does a kitchen extension add value to your house?

If you’re planning to add a kitchen extension to your property or perhaps you’re simply looking for ways to increase the value of your property, this is one of the common questions that usually pops up. A simple answer to this question is yes, a kitchen extension will add value to your house. With a kitchen being one of the most frequently used room in a house, adding an extra space to the commonly used room can only increase the value of the entire property. However, to determine the value added by such an extension, there’s a need to calculate the cost of setting one up first.

Kitchen extension costs are greatly influenced by a wide range of variables such as the size, type of the extension and specifications, your location, professional fees, materials used and more. Overall, the type of the extension you opt for will play the most significant role in the determination of your kitchen extension cost. Here, we’ll be looking at a single storey kitchen extension.

For a single storey kitchen extension, you can expect your home’s market value to increase within the range of 5 percent to about 10 percent. When trying to calculate the cost of kitchen extension, it’s crucial to take into account how much value it’ll add to your home so as to make sure that the amount expended will not outweigh the expected value to be added by the project.

For a more accurate idea, there’s the need to consult local estate agents. However, for a much needed guideline, single storey kitchen extensions are usually able to add about 5 to 10 percent to a home’s value, while double storey extension should be up to 20 percent. But as stated earlier, this will depend on several variables.
