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

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.

how much does a garage conversion cost?

Are you looking to create some more space in your home with your garage being almost dispensable? If yes, then considering a garage conversion project may be the way to go. Unlike many other extension options, garage conversion does not take up an additional space as it only changes the current structure of the garage. As a result, the cost of completing a garage conversion project can be relatively attractive when compared to other space creating alternatives. So exactly how much would a garage conversion project cost? Well, there’s no precise answer for this as several influencing factors come to play. However, in this guide we’ll give you a rough idea of the average costs that you’re likely going to encounter. Some of the factors that can influence your budget dramatically includes the following:

• The size of the conversion. The larger the size of the garage per square feet, the more cost you’ll have to expend.

• The type of your property - listed buildings are usually more expensive.

• Your location in the UK. If you stay in London where there’s a higher demand, you’ll most likely pay more.

• You’re likely to pay more if a specialist knowledge is required.

• The amount of glazing to be installed

• Quality of the materials to be incorporated.

• Quality of the professional to carry out the installation service.

On average, when it comes to garage conversion projects, you’re likely to pay the following depending on the per square metre given:

• A single garage of about 15 square metre will cost within the range of £6,000 to £15,000.

• A double garage of about 30 square metre will cost within the range of £12,000 to £30,000.

when do you need planning permission for a house extension?

If you’re planning on adding a house extension to your property, you’d probably be worried about whether or not your proposed extension would require a planing permission. Well, it may be relieving to know that not every house extension project would require a formal consent, and in fact, several extensions are covered by the permitted development rights. Not only can this save you a considerable amount of time especially at the project’s planning phase, but it’ll also save you money on the application fee. In the UK, single storey extensions to the house’s rear can be 3 metres deep for both semi detached houses and terraces or 8 metres deep for detached homes.

So how do you know when you’d require a planning permission for your home extension? Well, if your extension plan fits these criteria explained below, then your project is most likely going to be allowable as a permitted development.

• Extensions, which includes previous additions, must not go beyond half of the original house’s total surrounding land area.

• The main elevation, or side elevation where it fronts the highway, must not be extended forward.

• For single storeys, the rear additions must not extend more than the original house’s rear by more than 3 metres in both semi attached homes and terraces (4 metres for detached houses).

• Extensions to the side must be a single storey with a height not exceeding 4 metres and not going beyond 50% of the original house’s width.

• Extensions hat within 2 metres of a boundary should have a eaves height not more than 3 metres.

• Multi storey addition must not extend beyond the original house’s rear wall by a maximum of 3 metres or 7 metres of the boundary opposite the rear wall.

• Permitted development rights do not apply in listed buildings or designated areas.

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.

Are there grants available for external wall insulation?

External wall insulation works to keep your home cosy and comfy while also helping to cut the energy bills. However with the great benefits also comes great costs, so it’s actually a logical decision to know whether there are grants out there which you’re eligible for to help you handle the cost of the external wall insulation.

There are grants available for external wall insulation, but rarely will you find one that covers the full installation cost. With the help of the government’s Energy Company Obligation (ECO) scheme, a couple of energy companies assist in making your home more energy efficient by offering grants or free insulation. In certain cases whereby you receive particular state benefits, you may as well qualify for a higher grant that’ll cover more of the insulation cost.

However, if your energy supplier doesn’t offer any grant, you need not worry as you can save as much on energy bill after installation. Here’s what insulation can help you save per year on energy bills:

• Floor insulation can help you save within a range of £30 to £75 each year.

• Cavity wall insulation can help you save about £85 to £280 a year.

• Loft Insulation (270mm) can help you save about £135 to £250 a year.

Generally, the amount you’ll be able to save on your energy bills depends mainly on the type and size of your property, as well as how energy efficient it already is without the insulation. In the long run, your external wall insulation will more than give you back your investment on the valuable project through your savings on energy bills. In other words, whether or not you’re eligible for a grant should never stop you from installing an external wall insulation.

How to convert a basement into an apartment?

In some cases, it’s possible to convert a basement into an apartment. This can be a great way to incorporate an additional dwelling into your property and increase its value. However, converting a basement into an apartment can be quite expensive and time-consuming.

As with any type of dwelling, you’ll need to think about basic things like access, damp proofing, ventilation, insulation, heating, electrics, plumbing, lighting and décor. If you’re planning on extending your basement, then you’ll also need to ensure that your property is sufficiently supported.

It’s a good idea to consult a professional, like a basement conversion building specialist, to find out how feasible your project is before you go ahead with it.

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.

how much to refurbish a house?

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.
