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.

Builder FAQs

do i need planning permission to render my house?

If you’re considering rendering your house or property, then you’d most likely want to know whether or not applying for a planning permission will be needed. In several cases, planning permission will not be required for the maintenance, repair as well as replacement of the existing render on your building. These activities are covered by what’s called “Permitted Development Rights, which allows you to carry out some activities without having to apply for a planning permission but always subject to following some strict guidelines. For rendering, as long as the material (render) possesses an identical appearance to those existing on the house as well as same colour, then you will not require a planning permission. However, there are a number of projects that have been highlighted in which a planning permission would be required. These includes the following:

✓ Re-rendering in a colour that different from the original one used on the house or building.

✓ Rendering over brickwork which was not originally covered.

✓ Rendering over pebbledash

✓ Removing pebbledash and replacing it with render.

Another exception to the Permitted Development rights are for houses in conservation areas, national parks or areas of outstanding national beauty.

Although, you wouldn’t normally require to submit a planning application for approval before you apply render, but in truth it’s actually a bit of a grey area which isn’t totally clear and doesn’t allow for much freedom or creativity. And due to this fact, homeowners who wants an absolute peace of mind may opt to apply for planning permission just in case. It’s also worth noting that whether or not a planning permission is required, a huge rendering work will need to comply with building regulations which includes the need to insulate walls on the inside or outside as part of the work on several older properties .

What is plasterboard?

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.

What cement should I use for bricklaying?

Cement is a crucial element in bricklaying that’s widely used in both construction as well as finishing works. Generally, they’re used to aerate concrete blocks, connect bricks, prepare plaster, floor levelling as well as the making of precast products. The major reason cement is one of the most common construction materials as its incredible ability to hold structure together. To get a cement plaster, you’d simply have to mix cement with both water and sand. However, when you mix cement with lime, sand and water, you’ll get a mortar.

For cements mortars to be used inside joints, you’ll have to include 1 part cement at the minimum to not more than 2 parts sand by weight which should be dry mixed and moistened with enough water to allow for troweling and packing without falling apart. Generally, the cement sand ratio in a mortar is in between 1:2 to 1:6. The cement and sand mix ratio is largely based on the importance of the project.

Cement provides a plethora of uses in bricklaying and these includes:

• Preparation of cement concrete

• Preparation of cement mortar

• Building fireproof and thermal proof structures

• Building chemical proof structures

• Serving as a grout material

• Building hydrographic and frost resistant structures

• Manufacturing precast members

• Constructing aesthetic concrete

• Constructing cement concrete roads

There are several types of cements with each having its specific purpose. For instance, the type of cement more suited to building a fire proof structure is a high alumnia cement and to build a hydrographic structure, cements like expanding cement, hydrophobic cement, pozzolana cement and quick setting cement are the best bet. Acid resistant cements are more useful in building chemical proof structures, portland cements are best suited to making grout materials, while coloured cements are preferable to building aesthetic structures.

How much does external solid wall insulation cost?

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.

do i need building regs for a garage conversion?

Are you considering converting your garage into a more usable space in your home? If yes, then you’d probably want to know if you’ll require building regs before converting the garage. The answer to this question is yes. Although you may not require planning approval to convert your garage into a more usable space, but you’d usually need approval under the Building Regulations.

When re-structuring your garage into a habitable space, the following should be taken into consideration: structural alterations, ventilation, moisture proofing, insulation, fireproofing, escape routes as well as the submission of a building building notice or full plan application to the local council in order to inform them about the planned project.

• Walls

You’ll require an approval if you plan to infill the garage door with a window and a new wall. This is because the garage may have been built of a shallow slab which implies that a new foundation would be needed for the new wall construction.

• Floor

Even though there’s a high possibility that the garage floor is strong enough for domestic use since its designed to withstand the weight of vehicles, you may however need to upgrade to make sure it suitable for both thermal insulation and damp proofing. In addition, there may also be the need to to alter the floor level in such a way that it matches that of the remaining parts of the house.

• Ventilation

According to the Building Regulations requirements, there’s a need for adequate ventilation for each individual rooms which includes garage conversions for general health purposes. What’s going to determine the ventilation level that’ll be required is the frequency at which the room is used. Ventilation can be provided through purge or simply opening the window or via trickle ventilation.

How to fit external insulation?

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.

do i need planning permission for a garage conversion?

Are you thinking about converting your garage into a new space? Be it a new bedroom, gym, library or playroom, one thing you’ll have to consider before getting started is whether or not you’re going to require a planning permission. Unlike extensions that needs additional space, garage conversion is all about changing the existing structure of a space that’s already available to you - your garage. As a result, these projects are mostly covered by a planning policy that’s a bit different.

For a garage conversion, it’s very unlikely that you’ll need a planning permission. As a matter of fact, only 10 percent of garage conversions has been estimated to need a full planning permission, with the others coming under the permitted development rights. The permitted development rights, however, only provides coverage for home improvements that’s internal which implies that so far you’re not trying to enlarge your garage, you’ll not require a planning permission. But if otherwise, you’ll have to submit an application before commencing your project.

If you’re looking to comply with the permitted development rights, then your project must comply with some specific guidelines. These rules include the following:

• The work should be internal. No plans to enlarge or extend the existing garage.

• You should make sure that the materials used in carrying out the garage conversion is the same with the materials used in building the existing house.

• The building should not be extended.

You may, however, require a planning permission if you’re going to change a detached garage into a living space which could be a bedroom, small annexe or a living room.

Some houses excluded from the permitted development rights include flats, listed buildings, some new developments and most homes in a conservation area.

What is a barn conversion?

A barn conversion is where an agricultural building is altered to serve a different purpose. Lots of barns conversion projects involve converting an old barn into one or more homes. However, barns can also be converted into other types of commercial building, like offices.
