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

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 much do roof rooms cost?

How Much Do Roof Rooms Cost?

The price of your roof room may vary depending on your location within the country. Other factors that can also play a key role in determining the price of a roof room includes the conversion’s type as well as the legal and technical issues it’s currently facing. Usually, the cost of roof rooms will range between £1,200 to £2,000 per square metre. The differences in the price per square metre is influenced by the size of the alterations to the roof, the type of roof room to be constructed, the access, location as well as the finishing type.

• DORMER LOFT CONVERSION.

Here, one of the slopes of a pitched roof is substituted for a box-shaped structure. The outcome is a flat roof space which enables the fitting of full sized windows as well as the incorporation of several appliances. This is quite expensive as it involves a total rebuilding of one roof pitch alongside the complete internal works that are associated. The average cost of a standard dormer loft project will range between £25,000 to £50,000.

• HIP TO GABLE LOFT CONVERSION

Here a vertical brick wall is used to substitute the roof’s slope at the ending part of the terrace on detached buildings. The average cost of this type of roof room will range between £32,000 to £60,000.

• ROOFLIGHT LOFT CONVERSION

This basically involves fitting rooflight windows in the roof. Other improvements include flooring, plasterboarding, strengthening of the existing floor, as well as installation of rooflights. The average cost of this type of roof room will range between £15,000 to £25,000.

• MANSARD LOFT EXTENSION

This roof room can create an extra storey on top of an existing building as it makes a space featuring two or four external walls that are a bit sloped. The average cost of this type of roof room will range between £40,000 to £70,000.

how much does a single storey house extension cost?

If you’re planning to build a single story house extension, this is one of the first questions that usually comes to mind to help you set a budget and start to make plans. But as simple as it seems, a single accurate answer can not be provided due to the fact that there are several variables that can play a key role in influencing the price of a single story house extension. These variables includes the size, location, design or specification as well as the build route. In this guide, we’ll provide you with a rough estimate that you can work with to put you on the right path.

The main determinant of the cost of a single storey extension is the size of the build, while the next most relevant factor is the quality of the finish you opt for. For a small extension, you can expect to spend a sum within the range of £14,000 to £17,000. Meanwhile for a larger single storey extension, if you opt for a large wrap around the extension with a great amount of glass to be incorporated in both the walls and roof, you can expect to pay a sum within the range of £80,000 to £120,000.

Overall, the average cost of a single story house extension is usually within the range of £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.

There are some additional costs you may also need to factor in to your extension budget. These includes surveys, architect fees, planning application fee (if needed), insurance and Party Wall Agreement (if needed).

how to convert your loft into a room?

How To Convert Your Loft Into A Room

The loft is the space on top of a home that’s most often ignored by home owners due to having to consider the space’s configuration, the lighting as well as energy efficiency. However, when successfully converted into a room, it can serve several purposes which would even add more value to your property. So how can you convert your loft into a room? Let’s have a look.

• Take Into Account The Size Of Your Loft

The size of your loft is a major determinant of the type of room it can be converted into. A small-sized loft there’s a chance it can still be converted into an extra bathroom or home office while bigger lofts can be converted into an additional bedroom. The minimum head height is 2.3m, if your loft is lower than this, you’d have to get a planning permission to detach some parts of the room for extension.

• Include A Skylight

When a loft is poorly designed, the room become dark, shady and airless. Adding a skylight to your loft will let in fresh air, deliver better ventilation and more light.

• Insulate Your Loft

Loft insulation will not only prevent heat from escaping through the roof, but also lead to an improved energy efficiency which ultimately helps you save up on your heating bills.

• Use Modern Colourization

When you use bright, neutral and modern colours to paint your loft, you’re adding that elegant look to the space. As a result, the loft looks a lot more attractive and comfortable by the time you’re done with the conversion.

The conversion of your loft into a room can be a very tedious task if you wish to do it by yourself. We’d recommend you employ a seasoned professional for help in order to ensure the best results and also to avoid making costly mistakes.

does loft insulation cause condensation?

The short and simple answer to this question is yes, loft insulation does cause condensation. Over the years, problems with condensation in loft spaces have become increasingly common. While this may not be harmful in anyway, when the condensation becomes excessive it can lead to more serious issues taking root in your loft like wet rot, dry rot as well as black spot mould. Generally, the best thing to do if you’re concerned about the condensation in your loft space and that it may rapidly become a bigger problem is to get in touch with a damp specialist as soon as possible.

 

Even though insulating your loft space comes with a wide array of benefits like making the top floor rooms warmer, it’s however comes at the cost of making your loft or room space cooler. Condensation in lofts take place primarily due to the humid air making its way through insulation or other gaps into the loft space and touching a cooler surface which in turn results in beads of moisture on the timbers, lintels as well as the underside of the roof. This is why its always a great idea make use of thermal insulation with a vapour barrier that’s installed on the warmer side of the insulating material.

 

Condensation in loft is caused by excess moisture in the air and lack of adequate air ventilation. Here are some top reasons that gives rise to this in the loft:

  • Extra insulation has been installed in the loft leading to a restriction on the natural air circulation in the property.
  • When the storage boxes or other items that has been stockpiled in the loft blocks the roof vents.
  • The release of steam and moist air into the loft space by hot water tanks.
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.

What types of extension are there?

There are many different types of extension. For example, you could install an orangery, flat or pitched roof extension, over-structure extension, single or double storey extension or a glass box extension. Which one of these is most suitable will depend on your existing property.

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.
