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

are house extensions worth it?

Often referred to by many as the holy grail of home improvements, house extension comes with a wide range of benefits which makes it easy to see why the extension could be a great uptick in the potential price of your property in terms of sales. So if you’re looking to build a new home extension but still not convinced about the project, we’re here to help you. Being fully aware any home construction work is usually a heavy investment, there’s a huge need to be set on your decision before scheduling the commencement of any work. So are house extensions worth it? Below are some of the top benefits offered by house extensions to help you decide if it’s the most suitable route for you.

• Add To Your Home’s Value

Building an home extension is a great way to add value to your home before selling. Increasing the living space of your home is an incredible appeal to many buyers which significantly increases your property’s total value. However, you must ensure that the extension is impressively designed using top quality materials in order to generate more value.

• Good Alternative To House Moving

The most common reason for moving is usually due to a lack of sufficient space, but with house prices steadily on the increase a cost effective alternative is highly sought after. This alternative is house extension which creates more space for the household to spread out and have more privacy.

• You May Not Require A Planning Permission

You can extend your house and still not need to apply for a planning permission. To achieve this, simply comply with the laid down rules set under the permitted development rights.

• Extra Living Space

If you fill you’re starting to outgrow your existing structure and do not buy into the idea of moving, then your best bet might just be to extend your home.

how much loft insulation do I need?

Over the years, more and more home and property owners are beginning to realize the huge benefits that can be derived from loft insulation being a worthwhile investment. It’s quite worrisome the way in which energy bills have soared over the past 10 years and loft insulation is a considerable affordable energy efficiency measure that can go a long way to help increase your home’s energy savings.

 

As far back as the 1980’s, the standard when it comes to insulation thickness was 25 mm to 50 mm which was, at the time, considered to be sufficient. However, building regulations have changed the norm that now states that a new build needs to possess 270 mm of insulation in the loft in order to achieve the required u-value of less than 0.16/m2k based on the standard rock wool or sheep wool insulation.

 

Generally with loft insulation, there’s a law of depreciating returns which implies that the first couple of insulation centimetres will save you many times the cost of the installation, however an extra layer or centimetre is going to add less value to the point where it’ll no longer be wise or worthwhile to add any further centimetre. Therefore, with cheaper energy prices 30 years back, that additional couple of centimetres was not just worthwhile, but with the recent alarming rises in costs of fuel, that additional £10 savings per year has all of sudden changed to £30 which makes it become a lot more attractive.

 

If you already have 270 mm of loft insulation, regardless of the material you’re looking to add you’re most likely not going to benefit from a top up. The cost of the materials and installation will definitely be too high for the couple of pounds it’ll save you per year.

how to render a wall?

Wall rendering is basically a process which involves the application of sand, cement or polymer covering to a home’s exterior in such a way that enhances its look while also offering an improved stability. The process is a perfect solution for several exterior concerns mainly due to the support its able to provide. It’s highly beneficial for older homes whose walls may suffer from poor quality because of wear over time, while it’s also greatly advantageous for newer homes as it increases their stability while also enhancing their visual appeal.

Knowing how to apply render is a great skill to have with your home’s upkeep in mind. The project can be done quite easily by any competent and confident DIYer. However if you lack any of those attributes, then we’d recommend you get in touch with a reliable professional for help. In this article, we’ll take you through the wall rendering process.

✓ Prepare the walls. This involves examining the wall, repairing any structural defects as well as stabilizing any movements to prevent the render finish from failing.

✓ External details. This includes the removal of bargeboards, rainwater, soil pipes, alarm boxes and all other external details.

✓ Insulation. In the event whereby external wall insulation is to be fitted, this is the stage to do so.

✓ Developing a foundation for the render to fix to. Apply a render mesh over the insulation, bedded into the first base coat layer of render.

✓ Building up the render.

✓ Render finishes. There are a wide range of colour options as well as various finishes available from very smooth to textured. However, you should note that thin coat render systems are usually designed to be self coloured.

✓ Final finishes. This involves the re-application of the external rainwater, soil pipes and the other external details.

Why has my driveway cracked?

Driveway surfacing materials like concrete, asphalt and clay brick usually crack because they’ve been exposed to extreme temperatures or put under high pressure. It’s important to repair driveway cracks before they get worse and cause damage to vehicles and perhaps others to trip on raised cracks.

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.

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.

How much do bricklayers charge?

Do you want your house to be built using brick? Or perhaps you just require the professional services of a bricklayer. Regardless of your bricklaying needs, the cost charged depends on each job as every job is unique. Bricklayers generally look at each task individually and charges based on the complexity of each. We’ve put together this guide to give you an idea of the costs charged by bricklayers. Let’s have a look!

Generally, bricklayers charge either based on a daily rate or a fixed price for a particular amount of bricks ( usually a thousand bricks or 10 - 12 metres square). On the average, an experienced bricklayer can charge within a range of £150 to £200 daily rate and if a labour is needed for the job, an additional £60 to £100 may be included to get the job completed in a quick and fast manner. If the quoting is done based on the number of bricks to be incorporated, then a thousand bricks will be quoted in between £350 to £450 which should be completed in a couple of days.

You should however take note that most times, the bricklayer’s cost will depend on the amount of work involved in the project. As a result, a more tedious and challenging project will most definitely cost more than a simpler one. Examples of some difficult projects that’s likely to cost more are hard to reach areas, difficult sites as well as second storeys which are considered to be more challenging than single storey buildings. What’s more? The complexity of the project is also a great cost factor. While some projects are basically direct and straightforward, others involve curves and more complex designs which will ultimately make the cost jump up.

Can my loft be converted?

Many types of loft are suitable for a loft conversion. In general, you will need at least 2.3 metres of headroom in your existing loft. This is to make sure there is enough headroom after the conversion. Speak to a conversion specialist about the probability and possibility of doing this in your house.
