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

How to find a builder to refurbish my house?

After making the decision to refurbish your home or property, the next obvious step is finding the right builder to get the job done. The process of getting a good and reliable builder can be a very tricky one especially when you don’t plan ahead. And in truth, the outcome of your house refurbishment project can only be as good as the contractor your hire. Consequently, finding the perfect builder for your task should be a top priority to get the best return on investment. Here are a few sources that will put you in the right direction to finding a reliable home refurbishment company.

✓ Friends, Relatives & Neighbours

If you have a friend, relative or neighbour that have recently completed a home refurbishment project, you can go for a visit to check out the work done. If you’re pleased with the work, you can proceed to ask about the work ethics of the builder and get the contact if satisfied.

✓ Internet

With the rapid rise of online technology, there’s hardly a service you can’t find on the internet. Websites like HomeAdvisor have been helping people find their desired service providers with relative ease for so long. To get the right building contractor online, it’s advisable to check reviews as well as testimonials before moving forward. Nowadays, you’re most likely going to find so many positive online reviews as some businesses now go to the extent of dubiously writing good reviews for their companies. As a result, it’s recommended to pay closer attention to the negative reviews and check if it’s something you can cope with before hiring a contractor.

✓ Store Contact Lists

You’ll discover a long list of building contractors on several stores trading building materials. These builders may not be affiliated with the store owners, but many stores see it as their responsibility to point you in the right direction so that the building materials acquired from them can be put to good use.

how thick should render be on external wall?

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.

do you need planning permission for a garden room?

So you’ve identified the type of garden room you’d like to construct in your property, chances are, you’ve already worked out where to put it and can’t wait wait to start spending valuable time on it. It’s very understandable to be a little impatient with the whole idea considering the numerous benefits provided by a garden, but just before you proceed with your plans there’s the need to first check whether or not you’re going to need a planning permission.

Factors determining whether you’ll need a planning permission includes where you intend to place it, the size of the room, how it’s going to be used as well as your location.

Generally, most garden rooms do not require a planning permission as they are categorized as outbuildings. In other words, you’re permitted to construct one so far you comply with some specific rules and have permitted development rights at your home or in your area.

If you want to build your garden room under permitted development, you have to comply with the following rules:

✓ The garden room shouldn’t be in front of your home or property.

✓ The total area of your extensions, sheds and outbuildings ( which includes your garden room), must not go beyond 50 percent of the total land area surrounding your property.

✓ It must be a single storey that’s less than 3 metres high ( 4 metres for a dual pitched roof). And it must not go beyond 2.5 metres in height if the structure is within 2 metres of your boundary.

✓ The eaves must not go beyond 2.5 metres above ground level.

✓ It must not feature a balcony, veranda or any raised platform

✓ It must not be a self contained living accommodation.

You should note that if your home is a listed building or you happen to live in a designated area, then you might not have permitted development rights.

how to refurbish a house on a budget?

In the event whereby you’ve got big refurbishment ideas for your house but a small budget, then you know it’s time to be a bit more creative and apply some cheap and simple tricks. The best possible way to go about this is to invest time in acquiring new skills rather than trying to save up more money to pay a pro to deliver the results you want. After all, the most significant cost when it comes to house refurbishments is usually the labour cost.

The key to making cheap tricks a lot effective in the refurbishment process is by undertaking small tasks that’ll make a huge impact. A great way to start would be by taking it one task at a time rather than rushing to complete all at once. This way, you’ll have enough time to perfect your skills before moving on to the next.

✓ Paint the interior walls. Although this is a simple task but it’ll save you a lot of money if done as a DIY project. To get started, you’d have to text colour options by painting samplex on the wall first. Once done, you can go for the one that adds warmth, dynamism as well as energy to the room.

✓ Fix up your furniture. This involves re-upholstering and refinishing any piece of furniture that appears tired or overly worn (you can leave out the ones that you do not really like or unnecessary items).

✓ Spruce up small but important items used on a daily basis. This includes spray-painting inexpensive picture frames, recovering lampshades with a vibrant paper or patterned fabric, adding throw pillows to armchairs and couches and the likes.

✓ Fix all small things that are broken. This includes activities like patching the nail holes in the wall, repairing the latch on the kitchen cabinet, fixing the gutter, putting a new handle on the door and lots more.

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 long does underpinning last

Have you been advised by a structural engineer or a surveyor that your building needs to be underpinned? Well, this might just have you wondering what underpinning really is and how long it lasts. In this post, we’re going to tell you more about underpinning to help you make the best-informed decision possible moving forward. Let’s take a look!

Basically, underpinning refers to the incorporation of one of various methods to reinforce or repair the old foundations of a building or structure mostly to remedy or avoid subsidence. Now, subsidence can be caused as a result of poor soil quality, increase in the load on the foundation like adding a new storey, excavations below the building as well as inadequate foundation which is more common in older buildings. When an underpinning remedial work is carried out, there are a plethora of benefits that comes with it. It’s preserves the structural integrity of your building by strengthening it, make it a lot more attractive, increases the property’s value and makes it a lot safer for both you and your loved ones. So how long does underpinning last?

Well, many underpinning contractors will offer you a 10-year guarantee of its underpinning solutions for defects. Primarily, there are two reasons why underpinning can fail which is poor installation and fresh issues arising or unforeseen circumstances. While the first is an issue that can be avoided by employing the services of an expert contractor who possesses vast experience and knowledge in the field, the second can not be avoided. However, in the absence of the unforeseen issues, underpinning is expected to last for the natural life of the building, so far it has been expertly installed.

is cavity wall insulation a good idea?

Cavity wall insulation is basically the process of installing an insulating material between the two layers of brick making up a cavity wall, either as a retrofit measure or at the time of building. Obviously this is not a choice if you have solid wall, but for those who do possess a cavity wall, it represents an opportunity you may not want to let slide as it is a worthwhile and affordable wall insulation option. Clearly, cavity wall insulation will make your home or property feel warmer, but it also does come with a range of other benefits which is why we’d recommend installing it. In this post, we’re going to look at a number of reasons why having a cavity wall insulation done is a good idea.

  • It’s one of the cheapest energy saving measures that’s available. Not only is cavity wall insulation really effective, but it can also deliver great saving. In other words, it possesses a bigger payback compared to other options. When compared to other types of insulation, you can’t install cavity walls insulation by yourself, however it’s not so expensive to have it installed. The cost of the insulation will be determined by a number of factors such as your location, the company hired and more.
  • It reduces your energy bills. Cavity wall insulation can save you about £100 to £200 on a yearly basis on heating bills. In other words, this is usually able to pay for itself in as little as two years.
  • It reduces your carbon carbon footprint. If your home is heated with gas or electricity like several other homes, producing that energy involves burning fossil fuels which is known to be hazardous for the environment. If the heat generated is now allowed to escape through the walls, that means you’d have to use more to keep up your required temperature. Installation of cavity wall insulation in homes will enable a more efficient usage of the energy which will ultimately cut UK’s carbon usage.
how much to board a loft?

How Much To Board A Loft?

If you stay in a building where the space meant for storing stuffs is not sufficient, boarding your loft may be just the perfect solution for you. In several homes, the space is already present, and all you have to do is to make it more usable by boarding it out. This is unarguably one of the easiest and quickest ways to create storage space in your home.

Boarding a loft comes with a number of special benefits which includes:

• Assisting to declutter our living spaces and makes for a more spacious home.

• Creating a usable space whereby all seasonal items can be stored.

• Assisting to reduce heating bills as it prevents the loss of heat. When your loft is well boarded and insulated, it’ll help trap heat and prevent it from escaping via the roof.

• Adding to your home’s value by making your attic a very useful space for storing items.

• Helping to create a quiet space which can used for relaxation or getaway purposes and of course, this will require a bit more structural work.

So now that you’ve learnt a few of the benefits associated with boarding a loft, how much will it cost to have one made? This depends on an array of factors which includes the size of the space needed, the type of materials and labour cost.

Overall, a standard semi detached building will feature a lot of space of about 40 sqm to 50 sqm in size. There’ll be a need to add to the height of the floor joists before installing the chipboard decking boards. This job size should cost within the range of £1,000 to £1,500. It’ll require just a two-person team that are fully equipped and well versed about the processes.
