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

Are barn conversions cold?

If you’re considering converting a barn or buying one, you shouldn’t need to worry about it being cold. This is because building regulations dictate that when you convert a barn, you need to insulate it to meet specific standards. However, it’s worth considering its heating system and ceiling heights carefully – some barn conversions are likely to take longer and be more expensive to heat up than others.

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.

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.

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.

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.

do i need planning permission to render my house?

If you’re considering rendering your house or property, then you’d most likely want to know whether or not applying for a planning permission will be needed. In several cases, planning permission will not be required for the maintenance, repair as well as replacement of the existing render on your building. These activities are covered by what’s called “Permitted Development Rights, which allows you to carry out some activities without having to apply for a planning permission but always subject to following some strict guidelines. For rendering, as long as the material (render) possesses an identical appearance to those existing on the house as well as same colour, then you will not require a planning permission. However, there are a number of projects that have been highlighted in which a planning permission would be required. These includes the following:

✓ Re-rendering in a colour that different from the original one used on the house or building.

✓ Rendering over brickwork which was not originally covered.

✓ Rendering over pebbledash

✓ Removing pebbledash and replacing it with render.

Another exception to the Permitted Development rights are for houses in conservation areas, national parks or areas of outstanding national beauty.

Although, you wouldn’t normally require to submit a planning application for approval before you apply render, but in truth it’s actually a bit of a grey area which isn’t totally clear and doesn’t allow for much freedom or creativity. And due to this fact, homeowners who wants an absolute peace of mind may opt to apply for planning permission just in case. It’s also worth noting that whether or not a planning permission is required, a huge rendering work will need to comply with building regulations which includes the need to insulate walls on the inside or outside as part of the work on several older properties .

how to update old fitted wardrobes?

One of the main reasons why fitted wardrobes are a popular choice amongst homeowners is due to the fact that they’re able to help maximise storage space and since they’re usually customized for the particular room, they’re always good looking. However, just like any other home item, over time your installed wardrobe may start to look a bit dated and old fashioned. In these type of events and in order to save money, several homeowners would prefer to update its look to a more modern one without having to completely replace the fitted wardrobe with a new one. In this guide, we’ll give some great tips on how to update your old fitted wardrobe. Let’s take a look!

✓ Add mirrors to the wardrobe doors. Your old fitted wardrobe may be made of old fashioned laminate or chipboard which happens to draw scratches and dents here and there. If this is the case, you can simply add mirrors to help conceal the damage or unsightly marks.

✓ Include decorative trimming or panelling. You can choose from the various styles of trimmings you’ll find at hardware stores. By adding some strips of moulding, the whole look of your fitted wardrobe can change significantly.

✓ Painting. If the surface of the wardrobe permits, painting can go a long way to alter the look of the wardrobe.

✓ Change the handles. Handles may seem as a little item that doesn’t add to the aesthetics of the wardrobe. However, in reality, change your old handle with a more modern and fashionable one can make a great difference to the wardrobe’s overall appearance.

✓ Upgrade the interior. You can upgrade the interior of your wardrobe to give you more options and a better appearance. For instance, you may wish to have part of the wardrobe to offer integrated shelving or perhaps pull out drawers rather than having all the interior space for hanging clothes and garments.

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.
