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 to underpin a house

The importance of underpinning a house cannot be overemphasized. Firstly, what is underpinning? Well, underpinning is simply the act of reinforcing, repairing, strengthening or improving the depth of an existing foundation by lowering the footing to ensure that it rests more on more reliable and supportive soil. Not only does this method help to strengthen your building and preserve its structural integrity, but it also does increase your property’s value and gives you peace of mind knowing your property is safe. If you’re thinking about underpinning your house, you have two options – do it yourself or call in a reputable structural engineer. The latter is more advisable as the method involves a lot of specialized knowledge, skills and tools to guarantee a successful outcome. In this post, we’re going to take you through the process involved in underpinning a house. Let’s take a look!

To get started, you should know that concrete underpinning features excavating pier footings around the building at about 2 to 3 metres distance between each other. In some cases, underpins can be installed from within the house. The footings of the underpin should go very deep into the underlying soil in such a way that fully supports the weight of the building or structure. Once done, now proceed to attaching the new footing to the building. You can achieve this by excavating underneath the existing footing to make for a stronger prop. Individual prop and pier arrangement is then strengthened using strong steel bars. Once completed, the concrete is then poured.

A professional underpinning contractor will make sure there’s sufficient space left between the existing footings and the new underpins as this space will ensure that the new underpins can be easily used to jack up the house and level it once the poured concrete cures.

how to insulate a loft roof?

Insulating your loft roof comes with a wide range of benefits. Not only do you get to maintain a comfortable temperature in your house for longer, but you’ll also get to cut down on your heating bills. If you wish to insulate your loft roof, you’ve come to the right place! This process can be very tedious and time consuming especially if you don’t what you’re doing or lack the required confidence to pull it off. It’s advisable to hire the services of a reputable professional who can guarantee the best results for help and also save you some time and money that can come from potentially costly errors.

 

Before you start rolling out, you’d have to make sure that all cracks, gaps and holes in the ceiling are filled with either a standard filler or decorators caulk. You can also clean between between the gaps in the joists thoroughly. And finally, check for hazards that can cause you problems before getting stated.

  • Remember to leave ventilation gaps as you start from the eaves. Then work towards the loft’s centre, starting from the point furthest from the hatch.
  • Lay the first layer between the joists which should be 100 mm and then the subsequent layer should be 170 mm to make it up to the recommended 270 mm.
  • Carry the electric cables above the insulation and work around visible light fittings.
  • Cut the roll in the centre of the floor when rolling out from the eaves on both sides with the help of a craft knife. Ensure that there are no gaps between the insulation and the joists’ edges.
  • Lag pipes as you go in order to prevent walking over the insulation to get back to them.
  • Ensure that the loft is totally insulated
  • Insulate the hatch.
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 thick should loft insulation be?

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.

Can I extend my barn conversion?

Generally, it’s possible to extend a barn conversion, but there are certain conditions that you’ll probably need to meet. Ultimately, it’s up to your local planning office to decide whether to approve your planned barn conversion extension or not.

Typically, small extensions on the side of a barn conversion are often approved, particularly if they serve to preserve the original character of the barn. This could be because the extension will mimic the appearance of the original structure, or house facilities that would look odd in the original building.

However, you probably won’t be allowed to build a larger extension, or one that isn’t in keeping with the appearance of the original barn.

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 do I know if I have cavity wall insulation?

With cavity walls being very similar to other type of brick works, it can be quite confusing to figure out the type of wall your property possesses. If your house was constructed after the 1920s, then its highly likely the you have cavity walls, while older houses (houses before the 1920s) are likely to have solid walls. What’s more? If you happen to own a home that was built in the last decade, then it’s very possible that it was built with insulation installed during construction.

An effective way to determine whether or not your property is built with cavity wall is to examine the brickwork on your home’s exterior. The bricks will typically possess a regular pattern if it features cavity walls. In the event whereby the brick work is covered by render, you can also figure it out by taking a measurement of the wall’s width. If the brick wall is beyond 3000mm in thickness ( from the exterior wall to the interior wall), then it probably features a cavity. Meanwhile, a wall that’s narrower is very likely to be solid. Stone walls, on the other hand, may actually be thicker but are most times solid.

In a situation whereby your house is built using steel frame or timber frame, or made using pre-fabricated concrete, there are varying rules that applies when it comes to insulation and should be examined by an expert before any insulation is installed. More often than not, most contractors will have installed special air vents, which can also be a good indicator that a cavity wall insulation has been done.
