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
Over the years, garden rooms have gradually become a popular choice amongst homeowners as a cost effective way of expanding living space within a home or property. A garden room is basically a living space and a type of pavilion building made from wood that’s well insulated, double glazed as well as electrically wired. It’s however a building which is subsidiary to the main one, built with the purpose of creating an extra functional space within the property. These garden outbuildings are very functional and can be used as a garden studio, office, salon and much more. They can also be incorporated for recreational purposes for evening relaxations, family and friends get-together, lounge or even spa. Other possible uses of a garden room include gyms, pool houses, playrooms, dens, home cinemas and game rooms.
Garden rooms are functional living spaces that are usable throughout the year. And with the rate at which their popularity is growing, you’ll find some companies offering cheap and low quality alternatives featuring shed like construction and felt roof. Garden rooms, on the other hand, are a valuable investment with superior designs and top notch build. They’re constructed in a very similar way to houses with timber frames. Furthermore, they are fully insulated and can also include the normal building solutions such as heating and running water, electricity and many more depending on the requirements of the home or property owner. With the durability of garden rooms being a major objective, they’re typically clad in natural solid timber like Cedar, Larch or Acacia. Materials such as EPDM rubber or cedar shingles are normally used for the roof covering. What’s more? They usually have large expanses of glazing and glazed doors fitted.
If you’re thinking about refurbishing your house or property but don’t know how to go about it, then you’ve come to the right place. In truth, not every home refurbishment works goes in exactly the same order, however it’ll do you some good to abide by a specific plan in order to avoid both unnecessary works as well as expenses. For instance, how would it feel if you have already closed walls and paint only to realize that there’s a need to include a new plumbing stack that has to go behind the wall? Not good, right? Well, this guide is designed to help you avoid such frustrating situations. Let’s have a look!
✓ Establish a plan. This involves carrying out a good assessment of what you’d like to refurbish and set the priorities like deciding where to start and making sure you have both the time and budget to complete the project.
✓ Set a budget. Establish a final amount that’ll be the threshold to your spending. It’s always good to add an additional 10% to 15% to cover unexpected costs.
✓ Hire a contractor. Carry out a research, reach out to many contractors, compare their prices, work quality as well as integrity before hiring.
✓ Talk to your insurance company. Find out if you have the amount of coverage that suits your needs from your insurance company before and after your project.
✓ Secure permits and order materials. Make sure you check with the latest regulations before commencement. Once done, you can start ordering the required materials.
✓ Start demolition. This is optional as it only applies if space is being added.
✓ Work behind the walls. This include doing all the works necessary behind the walls like plumbing, electrical, heating etc.
✓ Paint and install flooring
✓ Fit in the cabinetry
✓ Add finishing touches. This includes the last details and decorations.
Planning permission is not normally needed for a loft conversion as they are covered by permitted development rights. A conversion company will tell you if you do and help you with this. For more information, see our article about planning permission.
Over the years there has been an increase in the recommended thickness of loft insulation by the government. Obviously, the reason behind this is pretty simply - the thicker the layer of your loft insulation the bigger your savings. The UK government is very keen to every house in the country to have loft insulation fitted where possible as it helps to minimize the heating demands of these properties. Households get to benefit from loft insulation in so many ways which includes reduced energy energy bills as well as having a home that stays at a more comfortable temperature for longer.
Generally, for the government energy efficiency is crucial as it implies that the highest demand ( which is usually the time of the day when gas or electricity use is at its peak ) reduces, since each building requires slightly less energy. Overall, that ultimately implies that new power plants don’t have to be built which is some nice cost savings for the government.
In the 1980’s, any thickness of loft insulation from 25 mm to 50 mm was considered the standard. But then, building regulations stated that homes should have as much as 100 mm of loft insulation. Over time, this gradually increased to 270mm for new builds and also recommended for other properties, although not essential. As a result of this, there’s always a need to check how much insulation you currently have in your loft before you decide to purchase more. You may discover that you already have something within the range of 20 mm to 200 mm up there and knowing this and the insulation values will assist in determining how much more you’ll need to purchase, if any at all. You should also note that some modern materials can offer the same thermal insulation whilst not being as thick.
Being the most used room in a house, it’s little surprise kitchen extension are usually one of the most popular requests in the UK. They do not only open up a frequently used space in your home, but also goes a long way to add value to your property. However, to know the value that’ll added you must first determine the cost of building such an extension before moving forward. Generally, a typical kitchen extension will cost within the range of £20,000 to about £50,000 plus VAT, based on the size of your project as well as your location.
In reality, a single accurate cost of a kitchen extension will vary depending on a lot of influencing factors, one of which is the type of the extension. Let’s take a look!
✓ Rear extension. You may want to consider this type, if you do not have sufficient space for a side return. This will extend your kitchen into your garden which implies that you’re going to give up some green space to make this a reality. The average price to have this done in London will be about £30,000 or more including VAT, and about £20,000 plus VAT or more in other areas.
✓ Side return extension. This, normally, isn’t a huge add to your property, but will create a lot of space for your kitchen while also be a lot reasonable in terms of cost. This type will extend your home into an alleyway at the side of your property if any is available there. On average, the cost of the side return extension should be about £50,000 plus VAT in London and a lot less in the other regions.
With the title of this blog, do not be deceived into thinking the purpose is to encourage you to install an external insulation by yourself. Even as a competent DIYer, it’s not advisable to buy a couple of materials and start slapping it into the wall hoping for the best outcome. External insulation is by no means a DIY job and without the proper training and experience, it can easily turn out disastrous resulting in loss of time, effort and money in such a valuable project. This blog, however, will give you a great insight on how the installation process works and help maximize knowledge ensuring you do not spend more than necessary.
External Insulation Installation
lRender Test
• This is done to ensure the existing render is good enough for insulation support.
• If positive, the insulation can be applied directly onto it.
• If negative, ensure removal of the old render before fitting the insulation.
lPipework Adjustment & Removal
• Remove all pipework prior to insulation fitting
• Install temporary downpipes to ensure water is not wasted and everything continue to function normally during the insulation fitting process.
lWindow Protection
• Protect the window with a protective layer or film.
lStarter Track Fitting
• Determine level you want the insulation to start (height).
• Fit the aluminium start track or carrier tray at the identified level.
lInsulation Boards Fitting
• Apply a layer of adhesive to the board and glue them to the wall in a staggered pattern.
• Cut to fit round all obstructions and windows.
• File off the edge of the board where necessary using a rasp upon successful fitting of the boards
lMechanical Fixing Inclusion
• Hammer around 10 fixings per square metre into the board.
• This is to secure the insulation boards.
lBeading Fitting
• Add corner beads and stop beads to ensure the insulation is secure and to prevent it from making contact with other materials.
lReinforcing Mesh & Render Addition
• Apply two layers of strengthening properties and between the two layers of render, include a fibre glass mesh.
lPrimer Application
• Paint on the primer
lFinal Render Application
• Choose your most preferred texture and colour as this will be the last coating of the installation process.
lPipework Re-installation
• Re-install all detached pipework at the start of the installation process.
How Much Do Roof Rooms Cost?
The price of your roof room may vary depending on your location within the country. Other factors that can also play a key role in determining the price of a roof room includes the conversion’s type as well as the legal and technical issues it’s currently facing. Usually, the cost of roof rooms will range between £1,200 to £2,000 per square metre. The differences in the price per square metre is influenced by the size of the alterations to the roof, the type of roof room to be constructed, the access, location as well as the finishing type.
• DORMER LOFT CONVERSION.
Here, one of the slopes of a pitched roof is substituted for a box-shaped structure. The outcome is a flat roof space which enables the fitting of full sized windows as well as the incorporation of several appliances. This is quite expensive as it involves a total rebuilding of one roof pitch alongside the complete internal works that are associated. The average cost of a standard dormer loft project will range between £25,000 to £50,000.
• HIP TO GABLE LOFT CONVERSION
Here a vertical brick wall is used to substitute the roof’s slope at the ending part of the terrace on detached buildings. The average cost of this type of roof room will range between £32,000 to £60,000.
• ROOFLIGHT LOFT CONVERSION
This basically involves fitting rooflight windows in the roof. Other improvements include flooring, plasterboarding, strengthening of the existing floor, as well as installation of rooflights. The average cost of this type of roof room will range between £15,000 to £25,000.
• MANSARD LOFT EXTENSION
This roof room can create an extra storey on top of an existing building as it makes a space featuring two or four external walls that are a bit sloped. The average cost of this type of roof room will range between £40,000 to £70,000.
