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

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.
Do I need planning permission for external wall insulation?

If you want to install an external wall, it is only wise to consider whether or not a planning permission is required in order to avoid a hefty fine. In a great kudos to the government and a welcome relief to home and property owners, the installation of external wall insulation is seen as an “improvement to the house and not an “extension or an “enlargement. Ultimately, this implies that external wall insulation fitting is to be done under permitted development and a planning application may not be required. However, like many other regulations, there are also exceptions to this rule and the main one is if the activity changes the appearance of your property. Properties such as a listed building having tighter regulations may pose some issues. As a result, we’d advise you to consult your local authority to ensure that there’s no fast rule to this topic before commencement of the external wall insulation project.

At the moment, according to the Government Building Regulations, the surface of the entire wall is to be improved to existing standards if the area to be insulated exceeds 25 percent of the wall. In normal situations this is usually the typical case, however to prevent avoidable fines and other possible punishments, it is always best to reach to your local authority and check out the rules guiding external wall insulation in your constituency. Furthermore, since external wall insulation is not a task that’s recommended to be done by yourself, you can also ask the professional external wall insulation fitting company for the applying rules before proceeding. As a good professional, the company should have a better knowledge of the rules and regulation guiding its activities.

can i refurbish a house in conservation area?

Due to the fact that we live in a country (the UK) with so much history as well as architectural beauty, there’s a need to have what’s commonly called “Conservation Area. A Conservation Area is basically an area which is designated by the local authority and is established in order to protect and enhance areas of historical and architectural interest which includes both rural and urban areas. Therefore, when it comes to refurbishment project in a conservation area, there’s usually a lot of things that needs to be put into consideration as well as hurdles to scale in order to make alterations to your property without any interruptions from the law.

In general, all properties in a conservation area have strict regulations governing the outlook of the houses, as this plays a major role in the appearance of the area as a whole. As a result, if you wish to bring down a building, fence, wall or even railing and the likes, you’ll need to obtain prior consent before you proceed. An easy way to go about any refurbishment plan is to to ensure the usage of exactly the same materials that exists in the current house. When you abide by the rules, you’ll be in a more favourable position to acquire the needed prior consent.

The short and simple answer to the question is yes, you can refurbish a house in a conservation area but subject to the approval of the local authority through a planning permission. And when it comes to submitting a planning application for approval, some are aspects will usually be subjected to more intense examinations than the others. Hence, the need to make sure that your refurbishment plans are all friendly in a similar way to the neighbouring buildings and environment.

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.
Why has my driveway cracked?

Driveway surfacing materials like concrete, asphalt and clay brick usually crack because they’ve been exposed to extreme temperatures or put under high pressure. It’s important to repair driveway cracks before they get worse and cause damage to vehicles and perhaps others to trip on raised cracks.

how much to re render a house?

Rendering of a house is one of those projects that can greatly improve the visual appeal of your home, enhance it’s energy efficiency, protect the brickwork from the elements and ultimately, add value to your home. Generally, the cost of rendering a house normally costs within the range of £25 to £70 per metre square, while the average cost house rendering costs stands at about £40 per square metre. Therefore, a 3 bedroom semi detached house will cost within the range of £4000 to about £5000.

The total cost of rendering a house is determined by a wide range of factors. These factors includes the following:

✓ Type of the rendering. There are three main types of rendering which includes sand and cement rendering, monocouche rendering as well as acrylic or silicone rendering. However, re-rendering applies to sand and cement sooner and it’ll also have to be painted every 3 to 6 years. Consequently, longer term cost can be higher when compared to the other types.

✓ Ease of access. Where your contractor will have to work around obstacles like shrubs or conservatory, this can make the cost a bit higher as it’ll take longer time to complete.

✓ Prep work. If the contractor needs to fill some cracks or perhaps an old mortar requires tuck pointing before rendering can be started, this will also affect the cost.

✓ Scaffolding. In the event whereby the job requires the use of scaffolding and you’ll have to hire one as a different cost, then the price will be higher.

✓ Your location. Due to the high standards of living and higher demands in areas like London or the Southeast, prices in these regions are usually higher than that of the other regions like Midlands and North.
