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

how long does a loft conversion take?

If you’re about to carry out a loft conversion project, you’d probably be wondering how long it’ll take to complete the task. Well, you’re not alone! This is one of the most common questions when it comes to loft conversion projects, however, providing a set timeframe for completion of such projects is impossible as all loft conversions vary. There are different factors that can determine the duration of your project. These factors include, the materials to be used, the type of the proposed loft conversion, the kind of staircase you’ll like to have installed, the number of windows included, the number of rooms to be added as well as a number of other influencing factors. As a result of these variables, the milestones and timings provided are only to be taken as guidelines. If you’d really like to have a set date, you can get in touch with a professional for help.

Generally, it’ll take up to 8 weeks to complete a loft conversion project.

✓ The first week activities will include putting up scaffolding, receiving the first materials for the build and creating an opening in the roof to gain access to the loft space.

✓ In the second week, the structure of the roof will be ammended and more support added.

✓ Third week, the floor joists will be fitted, building of the loft conversion will start, completion of the external roof works and commencement of plumbing and electric works.

✓ Fourth week, complete the building, construct the loft floor, fit the roof windows, insulation, ventilation and internal stud walls.

✓ Fifth week, apply plaster and plasterboard to the room walls, create a staircase opening and fit the new staircase.

✓ Sixth week, plaster the staircase area, complete plumbing and electrical works, hang the doors, fit skirting, handrails and bannisters and start decoration.

✓ Seventh week, complete the decoration and clean and wipe out all wastes.

✓ Eight week, complete all the remaining tasks.

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 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 much to refurbish a house?

Refurbishing a house brings about a plethora of benefits. These includes an increased sale value, an improvement on your quality of life or even simply to make it more visually appealing. All these are great when you look at them, but one thing that happens to be an hindrance for several homeowners is the cost of getting the project done. You may wish to set a budget, plan and prepare before commencement of the project, but the fact remains that, when it comes to refurbishing a house, nothing is certain. In fact, it’s advised to always expect the unexpected and have a lot of cash in reserve just in case something goes wrong. There are a wide range of factors that can play a key role in the overall cost of a house refurbishment. Minor refurbishment that should cost around £30,000 can easily go up to over a whooping £150,000 for a total transformation. Most of this cost will be expended on labour, and the next most significant expense, which is sourcing materials.

In general, the cost of your refurbishment project will depend on some factors which includes the size of the project, the materials used, the refurbishment or renovation level, the location of the property, the quality of the contractor hired and lots more. To estimate the cost of refurbishing your property, you can follow these simple steps:

✓ Write down a detailed list of all the things that needs to be done per room and try to be as specific as possible.

✓ Carry out a research of the labour cost in your area as well as the raw materials’ cost (here, you can make use of guides such as home advisor).

✓ Add an extra 10 to 15 percent on top of the calculated estimate for uprisings and repairs.

✓ Talk to your contractor to get a more accurate quote.

Are barn conversions a good investment?

A barn conversion can be a great investment for lots of reasons. When done well, barn conversions can be great at holding their value, meaning you could sell yours for a great price. They can also look fantastic, often with period features coupled with large areas of glazing. This can make them a great place to live, especially if you enjoy being in the countryside.

However, barn conversions do have their disadvantages. They may require extensive renovation work to bring their energy efficiency levels up to standard, which can be very expensive. It’s also important to be aware of their location – they might be on a working farm or close to several other converted buildings.

It’s essential to get a survey conducted before you buy a barn you plan to convert. This can tell you about any structural problems it might have and give you an indication of whether you might be able to get permission to convert it. You can also buy barns with planning permission already in place.

Does cavity wall insulation lead to damp problems?

Insulating a cavity wall should not affect the damp proofing of the wall. All insulation approved for use in cavity walls has been tested to ensure that it does not allow damp to pass through the wall. Some walls which receive a lot of wind driven rain are unsuitable for cavity wall insulation.

Can a mortgage include renovation costs?

In a nutshell, a mortgage loan is for the acquisition of an asset, so lenders won’t tend to give you anything else in a mortgage that is going to cover your home renovation costs. When you are applying for your mortgage, your provider will examine the price of your new household. For example, if you’re planning to buy a property for £200,000, but you need another £50,000 to help improve it, you’ll find that your lender might turn you down.

Essentially, with any mortgage loans that you take out on your possessions, the bank or creditor theoretically owns your home till you’ve entirely paid off your loan, which is why it is very unlikely that you will get extra funds from them. There are some mortgage providers who will be willing to add on some building costs, but it is entirely up to you whether to choose it or not.

With most mortgages, banks and other lenders will usually give you a maximum of 95% of what you purchased your property for. That means, that even if you contemplate the household has the probability to be valued at so much more, you’ll have to find an alternative way of paying for the developments you have in attention. So, if the accumulation of extra funds on to your mortgage loan is out of the question, you’ll need to find additional ways of paying for the home developments.

It is well and good if you have the cash saved up, or else, you can explore other payment options which your bank or lender may be able to help you with. There are several methods by which you can collect the cost to pay for the improvements, from personal loans to credit cards or even overdrafts, there are tons of ways to lending money. Keep in mind these are all forms of debt so keep an eye out for the interest rates when you are repaying.

Can an extension add value to my home?

Yes. Most extensions will add substantial value to your home, and you may find that the extension adds more value than it cost. However, it’s important to be sure that the home remains balanced. Extending your garage and leaving your property with no parking spaces, for example, may impact your ability to sell.
