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 does loft insulation work?

A lot of an uninsulated property’s heat is lost through the roof and that’s even more alarming, when you realize this figure is up to a quarter of the total heat of the house. Hence, the tremendous importance of preventing this heat loss through loft insulation which will go a long way to help you against spending unnecessary thousands of pounds on heating bill as well as energy loss.

 

Loft insulation is an effective method to achieve the desired result, however the question is, how exactly does it work? Well, it’s time to find out!

 

Using either a fireplace or central heating to heat up your home, a large quantity of that heat would be lost through the roof of your home. Generally, heat rises and when it does, there’s simply no way to prevent it - it’s just science. Escaping by both the conduction and convection methods via your roof, the heat escaping through your ceiling, into the loft space and out into the open air outside can only be significantly reduced by laying loft insulation.

 

Generally, the added layer of insulation works by trapping the heat inside the room below the loft so as to enable the air within your house to stay warmer for longer. What’s more? The layer of insulation also keeps cold air from the outside from entering your home. As a result, you don’t have to heat your home as much in order to achieve the same temperature for each individual room. Over time, just by doing this you can potentially save hundreds pounds. Getting it installed in your home may actually seem a bit expensive at first, but it’s something that’ll eventually pay off.

what is a garden room?

Over the years, garden rooms have gradually become a popular choice amongst homeowners as a cost effective way of expanding living space within a home or property. A garden room is basically a living space and a type of pavilion building made from wood that’s well insulated, double glazed as well as electrically wired. It’s however a building which is subsidiary to the main one, built with the purpose of creating an extra functional space within the property. These garden outbuildings are very functional and can be used as a garden studio, office, salon and much more. They can also be incorporated for recreational purposes for evening relaxations, family and friends get-together, lounge or even spa. Other possible uses of a garden room include gyms, pool houses, playrooms, dens, home cinemas and game rooms.

Garden rooms are functional living spaces that are usable throughout the year. And with the rate at which their popularity is growing, you’ll find some companies offering cheap and low quality alternatives featuring shed like construction and felt roof. Garden rooms, on the other hand, are a valuable investment with superior designs and top notch build. They’re constructed in a very similar way to houses with timber frames. Furthermore, they are fully insulated and can also include the normal building solutions such as heating and running water, electricity and many more depending on the requirements of the home or property owner. With the durability of garden rooms being a major objective, they’re typically clad in natural solid timber like Cedar, Larch or Acacia. Materials such as EPDM rubber or cedar shingles are normally used for the roof covering. What’s more? They usually have large expanses of glazing and glazed doors fitted.

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.

do fitted wardrobes add value to your home?

The short and simple answer is yes, fitted wardrobes add value to any home or property. Owning a home is mostly the single most expensive asset that a person can possess. And as a result, your home is a very special asset that you’d want to make conducive and maintain to the best of your ability. To retain the value of your home or even add to it, you have to learn how to maximize its potentials using different means. In the UK, a big issue for most households is usually the lack of storage space and most especially, the quickly shaped bedrooms which is really affected with storage problems. It almost always seems like there isn’t enough space to keep our clothes as well as the never-ending portfolio of accessories, devices and gadgets. Therefore, an extra or excess usable room inside a home is always a premium.

In other words maximizing the space you have, especially the unused ones, is a great way to add value to your property. Custom made fitted wardrobes are a great means to making the most out of the space within your home and are also designed to last for several years. Unlike the freestanding wardrobes, modern and fitted wardrobes are not only visually appealing, but they’re also customizable to fully maximize every inch of space within the room. As a result, they’re the ideal solution especially for loft rooms where the bedroom may be slope or oddly shaped to make the best out of the space available.

Potential investors are always eager to invest in homes with enough space that are well maximized. Therefore, a fitted wardrobe will not only help you create a better demand for your home at the point of selling, but it’ll also go a long to increase its value in so many ways.

how to repair asphalt driveway depressions?

When your driveway is suffering from depression, it becomes unsafe for driving (a danger zone) and ugly - no homeowner wants that! Unfortunately, most driveways won’t hold flat for long as they tend to develop cracks and potholes pretty quickly. Here, we are going to take you through how to fill asphalt driveways’ depression so as to ensure the sinkholes in your driveway poses no threat to you or your loved ones, while also beautifying your property. The approach to be used depends on the intensity of the depression. If its only a few cracks and holes, this can easily be repaired with some equipment. But if otherwise is the case, then calling a reliable professional will be your best bet. In this article, we’ll show you how to repair dips in your asphalt driveway relatively quickly.

✓ Pick a date with warm and sunny weather. This is because if you work in a cold weather, chances are the materials will freeze and hence, unusable. So find a day when the temperature will over 50 degrees Fahrenheit and below 80 degrees Celsius and when there would be no rain. We’ll advise a day between May to October.

✓ Prepare the area. Remove all loose stones, soil, dirt as well as vegetation from the holes. Once done, you can then proceed to washing the area with a pressure washer or sweep with a broom.

✓ Apply a thin mixture of asphalt to the area. Use a flat stirring stick to coat the low driveway area with a thin mixture of asphalt.

✓ Tamp the asphalt repair mix. Purchase the right kind of asphalt to repair the driveway. Fine aggregate asphalt mixture is more suited to filling small holes, whereas the coarse aggregate is more suited to filling larger holes. Apply layers ( about 2 inches each time) of the asphalt repair mix to the sunken area and use a shovel to give it a smooth finish. Once done, simply make the area smooth and protect it with a piece of plywood. Do not walk or drive on the area for a couple of days.

do you need planning permission for a porch?

There are so many benefits that comes with building a porch in your home premises. It’s an extra space where a lot can be achieved such as drying a dripping wet dog, taking off your dirty shoes or boot and lots more. So if you’re considering to construct a porch, it’s definitely going to be a wise decision. However, before you get started, there’s a need to determine if you’ll need planning permission for a porch. It’s important to take note that planning laws are dynamic and can be updated at any point, so be sure only to use trusted sources only as your guide. If you’re the homeowner or landlord, it’s entirely your responsibility to obtain the right approval for any development project you wish to carry out within your premises.

A Porch can not be termed as an extension and neither is it a conservatory, they’re basically built to the home’s front covering the main entrance using a stone base or a brick. As a result, a porch does not need planning permission due to the fact that it’s covered by the permitted development rights if the specific guidelines for porches are complied with. Below are the instances where you WILL need planning permission for a porch.

✓ If the floor space is more than 3sqm (the wall inclusive).

✓ The highest point has a height of more than 3 metres.

✓ If the porch is situated within 2 metres of a boundary directly facing on to the road.

You may need planning permission if the house is a listed building, designated area or falls under an Article 4 Direction.

In order to build a porch without planning permission, you need to consider all the criteria stated above. You can also visit the Planning Portal website to get more detailed information before getting started.

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.

does a single storey extension add value to your house?

Does A Single Storey Extension Add Value To Your House?

When you’re looking to construct a single storey extension or perhaps you’re just searching for means to increase the value of your property, this question always pops up. The short and simple answer to this question is a resounding yes, a single storey extension can go a long way to increase the value of your property. Just like any other home improvement, when done right, adding a little extra living space is one of the top things you can probably think of that’ll provide a cool increase in your property’s value. However, before you rush in you must also take note of some factors so you can be certain a single storey extension is the right option for you. These factors include the quality of the build, complexity of the build, cost of the build versus the value gain, ceiling price in the area, finance costs as well as the inconveniences and stress.

Generally, the average cost of a single storey extension can range from £34,000 to £37,000. For this price, you should get a standard sized rear or side extension which also includes the cost of a kitchen - it’s the most commonly use for a single story extension especially in the UK. So it’s important to know the value they’ll add to your house before deciding to make such an investment.

The value added to your property will depend largely on the quality and size of your single storey extension. The value is usually calculated by estate agents using the number of bedrooms, bathrooms as well as the floor area. Inside London, it’ll typically be priced at £5,000 to £10,000 per square metre, while outside London should be within the range of £900 to £2,000 per square metre.
