How much do Builder services cost?
How much do Builders cost? Prices for Builders in 2025 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.

Services offered by Builder
The tasks of a builder vary widely, however in general; builders are responsible for the coordination of different types of construction involved in erecting a structure or building a house, office or any other building. The architect, on the other hand, is assigned the duty of designing the structure and creating the blueprints while the builder will take charge of bringing the ideas to life by overseeing the construction process. In addition, a builder will be involved in getting any relevant building permits as well as consents and have the land surveyed to determine what would be required in the way of drainage and lots more. Once they have surveyed and prepared the land, the builder will kick start the building process. Generally, they’ll remain on-site throughout the building process so as to make sure that the structure is built the proper way and in line with the laid down plans.
For instance, during a new build, a builder will first supervise the laying of the foundation then the house frame being erected followed by the roof. Once done, they’ll then work closely with other tradespeople such as plumbers and electricians in order to get power as well as water to the house. Other tradesmen may be hired to complete various tasks. For example, a carpenter may be needed for the flooring, landscapers to take care of the front yard, painters to paint the entire house both interior and exterior and lots more. Due to the fact that a builder will have to organize all these tradespeople, they need to have a good understanding of these different fields in order to ensure that the job is done the right way and in the correct order.

Builder FAQs
What Is Plasterboard?
The plasterboard is unarguably one of the most common building materials across the globe. Sometimes referred to as gypsum board, gyprock, drywall or wall board, the plasterboard is mostly incorporated for ceiling cladding and interior walls in several homes and offices in recent times. However, despite its global acceptability, it’s a very misunderstood building material.
The plasterboard is manufactured using a gypsum core with a heavy paper covering both sides of the sheet. The measurement of a standard plasterboard sheet is a length of 2.4 metres in and a width of 1.2 metres, with a thickness of about 13mm. The board usually have either a bevelled or a bit flat edge. The bevelled edge makes it easy for the installers to use a plaster to smooth out the surface after nailing the sheets to walls and ceilings as well as taping the edges.
The plasterboard comes in different types. Although various manufacturers provide a unique name for their products, but they’re all included in one of the following categories:
• Water Resistant Plasterboard - This type of plasterboard are best suited to be used in water areas like bathroom, laundry rooms and kitchens.
• Acoustic Plasterboard - Due to its sounding proofing qualities, this type of plasterboard is preferred to be used in home theatres or noisy areas.
• Flexible Plasterboard - This is to be incorporated on curvy surfaces.
• Fire Resistant Plasterboard - Just like the name implies, this type of plasterboard is best suited for use in high fire hazard areas.
If you’re about to kick start some small renovations around your house or office, using a plasterboard to clad your walls is a very simple and worthwhile task. However, if you want to do major renovations or need to apply plasterboard to your ceiling, the best option would be to leave it to a seasoned professional.
Refurbishing a house brings about a plethora of benefits. These includes an increased sale value, an improvement on your quality of life or even simply to make it more visually appealing. All these are great when you look at them, but one thing that happens to be an hindrance for several homeowners is the cost of getting the project done. You may wish to set a budget, plan and prepare before commencement of the project, but the fact remains that, when it comes to refurbishing a house, nothing is certain. In fact, it’s advised to always expect the unexpected and have a lot of cash in reserve just in case something goes wrong. There are a wide range of factors that can play a key role in the overall cost of a house refurbishment. Minor refurbishment that should cost around £30,000 can easily go up to over a whooping £150,000 for a total transformation. Most of this cost will be expended on labour, and the next most significant expense, which is sourcing materials.
In general, the cost of your refurbishment project will depend on some factors which includes the size of the project, the materials used, the refurbishment or renovation level, the location of the property, the quality of the contractor hired and lots more. To estimate the cost of refurbishing your property, you can follow these simple steps:
✓ Write down a detailed list of all the things that needs to be done per room and try to be as specific as possible.
✓ Carry out a research of the labour cost in your area as well as the raw materials’ cost (here, you can make use of guides such as home advisor).
✓ Add an extra 10 to 15 percent on top of the calculated estimate for uprisings and repairs.
✓ Talk to your contractor to get a more accurate quote.
Before the commencement of any project, it’s always best to get an estimation of the cost. However, determining the cost of an external solid wall insulation is not the easiest of tasks as it relies on varying components such as the insulation materials to be used, labour cost and installation as well as the type of decorative finish to be incorporated. And depending on your choice of insulation material, some may need some adhesives while others may require some fixings which also contributes to the differences in price. As a result, the determination of the material cost alone can be tricky and even more so when various materials cover varying areas.
With that in mind, the cost of external solid wall insulation generally ranges between £80 to £100 per square metre2. As a result, a small flat can cost from £6000 to £9000 whereas a large detached house can have a price ranging between £21000 to £23000. To earn back your investment in terms of energy bill savings can take a couple of years, but it’s surely worth the try as there are several other benefits associated with installing an external solid wall insulation system. What’s more? Another huge factor that can influence the cost of your system is also the amount of work that’s required, how easy it is to be accessed by the installers and lots more
If you’re looking to cut down on the cost of your external solid wall insulation, then the best time for an installation might just be when you’re having another decorating or building project done such as fitting a new roof, window painting, installation of solar PV panels and more. This way, you’ll be able to spread the cost and have a greater value for each penny expended.
Render serves two basic functions. One is it’s protective qualities as render acts as waterproof for the wall which enables them breathe by allowing water vapour move from the inside to the outside of the structure while also working to prevent water or rain from finding its way inside the structure. While the second function is the decorative qualities as render is able to provide the structure with a fine finish and colour to make the building a lot more appealing and correcting faults in line and level in the masonry.
If you wish to apply render on your external wall, you’d probably be wondering just how thick the render should be to perfectly serve both of functions. In this article, we’re going to take a look at just that!
For a render thickness, the British Standard Wind Driven Rain Index has come up with 4 ratings which include Sheltered, Moderate, Severe as well as Very Severe. An area with Very Severe rating include South West England. This rating implies that the thickness of the render in this area should be increased to at least 20mm for a direct one coat render applications as well as 5 to 6 external wall insulation base coat applications. And if you happen to reside within one mile of the coast, it’s strongly recommended you incorporate an extra repellent protection like Paraguard AG from Parex.
In general, render that’s prepared on site with cement and sand should be have a minimum of 20mm to 25mm thickness. Although, it should be noted that the quality of the render is based on quality of the sand incorporated, the design mix as well as being largely dependent on how good the mixing technique from the applicator is. The most common reasons why traditional renders fails is due to both poor mixing ratios and low quality materials used.
Most companies will make the building control application on your behalf and ensure that all the work is completed to the right standards. When a building inspector has inspected it, you’ll get a certificate. It usually takes around 6-8 weeks after completion to come.
Are you interested in extending your home to create more living space? If yes, then you’d probably want to know how much value it can add to your property in order to compare the building costs to the potential value gain. Well, as long as you know what you’re doing, your house doesn’t necessarily have to be a money pit. So what are your options when talking about home extensions and what’s the associated value to be gained?
• Bathroom Extensions
Although you should have it in mind that bathroom extensions isn’t usually that cheap, but once done, it can increase the value of a standard UK house within the range of £12,000 to £15,000. Meanwhile the finishing cost of a bathroom can range from £2,500 to £7,000.
• Single or Double Storey Extensions
Single storey extensions are always huge when it comes to increasing the value of your home - giving about 4 to 7 percent increase. If it goes that far, then literally nothing beats a full spectrum, double storey extension which can give up to 11 percent increase in the value of a property - equalling about a whooping £33,000 for a standard home in the UK.
• Conservatory Extension
With conservatories becoming more and more popular in the UK due to the weather conditions, several buyers are now including it’s availability as part of the criteria for purchasing a house. Wonder why? This is simply because everyone wants to enjoy their garden all throughout the year. As a result of this high demand, adding this type of extension to your house can go a long way to increase it’s value. However, it’s very important to incorporate high quality materials during construction. With glass conservatories offering, on the average, up to £5,000 increase in value, the cheaper PVC alternative offers much less value and can also deter potential buyers.
You may need planning permission if you are planning a larger extension. All extensions will need building regulations approval. An architect can assist with this and if planning permission is required. A reputable contractor will also be able to advise you if this is needed as well.
