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 much does it cost to renovate a house?

Presenting with its unique sets of components, the price for every house renovation project varies considerably. Though giving a proper price for the house renovation is not possible, you can generally expect to pay anything between £40,000 and £75,000 for renovating a three-bedroom house.

You must list out all the changes needed since renovation comes with several potential costs. This makes it easier for you to calculate the renovation costs and start planning your budget accordingly.

Let us take a look at some of the crucial factors that affect the cost of renovating a house

• Property size

• Property’s condition and age

• Complexity oof the job

• Structural work

• Building extension work

• The quality of materials, fixtures and finishing

• Decoration

• Location

When it comes to renovating a three-bedroom house, the average cost is around £ 57,000. A new gas supply will cost you around £1,500, depending on the route of the supply. There may other additional costs involved if you are looking to do any work to extend the gas supply line.

The cost of rewiring a house is in the region of £5,750. That price will also be dependent on the complexity of the electrical systems in your house and the size. If you are looking at installing a new set of windows, it can cost you up to £6,000, with the average cost being about £4,250. Replastering walls will add another £2500 to the total budget. A new kitchen will set you back around £7,000, on average including the cost of design, materials and installation. Most renovations will need a new bathroom. Installing a new bathroom will cost you around £4,250.

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.

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 is a porch?

If you’ve decided to construct a porch to your property and now looking to figure out the cost required to complete the project, then you’re at the right place!

There are many factors that comes to play when determining the price of building a porch. These factors includes the size of the porch, the number of windows, the style of the roof as well as the type of the porch selected. Now let’s take a look at these factors one after the other.

• The Porch’s Size

As you would have correctly imagined, a large porch will definitely cost more money than a smaller one. A rough estimate of a porch’s cost per square metre is approximately £1,400.

• The Number Of Windows

Just like in the scenario above, the more the number of windows to be incorporated, the more money you’ll have to pay to complete your porch. A porch window will generally cost you within a range of £300 to £1,000

• The Style Of The Roof

There are two popular styles of porch’s roof which includes a tiled rood and a rubber flat roof. Generally, roof tiles are costlier than a rubber flat roof. A tiled roof would cost you between £0.80 to £1.80 per roof tile, while a rubber roofing will cost your between £70 to £90 per metre squared.

• Type Of The Porch

Another huge determinant of a porch’s price is type of material incorporated. For instance, if your preferred type is a lean-to, the price of a uPVC would be between £2,300 to £2,700. Meanwhile, a flat gable roof porch should cost within a range of £3,300 to £3,800.

Kindly note that the costs quoted in this article are only rough estimates, for a more accurate estimate you can contact a porch building professional within your local area.

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.

how much does a two storey house extension cost?

If you’re considering adding a two storey house extension, then setting a budget for this project would be a great way to get started. Similar to a rear extension, a two storey extension usually leaves the rest of the building needing some work and, due to its size, this may imply the re-development of the entire house - which is why they can be very costly. Some of the other influencing factors that can have big impact on a two storey house extension cost includes: your location, the size of the build, complexity of the design ( anything beyond the standard build will normally require more expertise and time), the glazing to be incorporated ( the more the glass used in the project, the more the material cost), as well as the team used.

Generally, when it comes to extensions, the major part of the expenses will be made on the build of the project. This is because it doesn’t only cover the material cost but also the contractor’s overhead as well as the daily rates. At this stage, the extension prices can be determined by the standard of the work that’s being done.

For a fairly average room size of about 18 square metre, the two storey extension should cost within the range of £2,500 to £3,000 per square metre - with the range being determined by the finishes incorporated. Therefore, a two storey extension of about 18 square metre should cost within the range of £45,000 to £55,000. However, this is with the assumption that there are standard window sizes, bathroom suits are modest, and without any need for any purpose joinery or glazing. If you wish to include all these extra features you’ll also have to pay more to make the total cost between £70,000 to £80,000.

how much does a loft room cost?

How Much Does A Loft Room Cost

In the event whereby you happen to run out of space in your home and extending sideways or moving out isn’t even a considerable option, the next best solution is to look upwards - the loft. The loft can be converted into a room that can used to satisfy varying purposes, be it a storage room, bedroom, home office, spare bathroom and more. There are a number of loft conversion styles you can go for including a room in loft conversion, dormer style conversion, mansard conversion, or a hip-to-gable conversion. Regardless of your choice, each of the types will not only give you new rooms to enjoy but also add value to your home. However, before getting started, it’s crucial to have an idea of the loft conversion cost to help you prepare a budget and begin planning. Here, you’ll discover the most likely loft room cost for each conversion style you opt for.

• Room In Loft Conversion

This is only suitable for some specific home, but it’s however the most affordable option of the lots. This loft conversion style will cost within the range of £15,000 to £20,000 (prices can be higher in regions where tradesmen are higher in demand such as London and the south east).

• Dormer Loft Conversion

These are relatively simple and straightforward to include in your home. The cost ranges between £31,000 to £58,000 depending on the conversion’s size and other factors.

• Hip To Gable Loft Conversion

This style of loft conversion is more complex than the aforementioned ones, hence they’re usually more costly to complete. The price ranges between £42,000 to £65,000.

• Mansard Loft Conversion

This style of loft conversion is the most complex of the lot and includes a complete overhaul of your loft. The price ranges between £45,000 to £70,000.

• Bungalow Loft Conversion

Any of the main styles above can be done to a bungalow if the planning requirements are fully complied with and if the property is suitable. The price ranges between £30,000 to £70,000.

How to put up plasterboard?

How To Put Up Plasterboard

Putting up a plasterboard is a vital process when it comes to home renovations. However as daunting as it may seem, with a good guide and regular practice you can master the skill within a small period of time. If you lack proper training and experience, we’d recommend you hire a seasoned professional plasterer for help so as to get the best result and also avoid additional costs due to possible damages.

Putting up plasterboard is way quicker than wet plastering and also significantly reduces the drying time that can slow down your renovation plans. With a plasterboard, you can delve straight into the decorating stage and achieve a smooth finish. Below are the steps required to put up a plasterboard.

• The first step is cutting the plasterboard to shape which be one of the most challenging parts of the process. This is because you’ll need to fit the board around things such as plug sockets and window sills. As a result, this involves cutting complex shapes rather than just a simple straight line. To get this done, simply mark out the cut required with the use of a tape measure, combination square and spirit level for a better precision. Once done, you can then use a plasterboard pad saw to cut along the marked spots.

• After you made the required cuts, the next step is putting up the plasterboard. And depending on where the boards are going to be put, this could be a very challenging task. If you’re going to put the boards on the ceiling or somewhere very high up, you’d probably need an extra pair of hands for help. To get this done, use the appropriate screws to secure the boards in place if you’re installing them directly on studs. However, if you’d be fixing them onto bricks or blocks, a drywall adhesive is your best bet.
