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

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.

are house extensions worth it?

So if you’re looking to build a new home extension but still not convinced about the project, we’re here to help you. Being fully aware any home construction work is usually a heavy investment, there’s a huge need to be set on your decision before scheduling the commencement of any work. So are house extensions worth it? Below are some of the top benefits offered by house extensions to help you decide if it’s the most suitable route for you.

• Add To Your Home’s Value

Building an home extension is a great way to add value to your home before selling. Increasing the living space of your home is an incredible appeal to many buyers which significantly increases your property’s total value. However, you must ensure that the extension is impressively designed using top quality materials in order to generate more value.

In this article, we aim to look at the cost of rendering a house using the standard 3 bed house as an example. Firstly, it should be stated that there are numerous factors that affects the price of a rendering a house which includes the rendering type, the size of the house, the ease of access, the prep work required, whether or not scaffolding will be needed as well as your location and the quality of the contractor your hire. Out of all these factors, the most significant variables are probably the type of rendering you go for and the size of the house.

There are three types of render and the one you opt for will play a key role in the price of your 3 bed house. In this article, we’re basing our cost estimate for a 3 bed house (3 bed detached) on the size ranging from 110 per square metre to 160 per square metre.

how to repair a pothole in gravel driveways?

How To Repair A Pothole In Gravel Driveways

When the integrity of your gravel driveway is impaired not only does it have a negative impact on the curb appeal of your property, but also makes your driveway a danger zone. If your driveway needs to be repaired, you’d simply have to grab the bull by the horn and get it done - the sooner, the better to avoid the problem getting worse and to have your beautiful gravel driveway back as soon as possible.

The major cause of potholes in driveways is usually water, when it gets trapped beneath the surface of the driveway. Therefore, you may also want to enhance the drainage in the area as part of your repair. The repair process is quite simple for confident do-it-yourselfers, but if otherwise, then calling in a reliable professional will save you some time and extra money that can result from possible errors. So how do you repair gravel driveway potholes?

✓ Prepare the area. This involves removing all forms of debris from the pothole. To achieve this, you can rake, shovel or brush the loose stones, soil and other debris from the pothole.

✓ Fill the pot hole. Make use of a coarse gravel to fill up the pothole to a depth of about 3 inches beneath the driveway’s level. Upon the filling, simply tamp down the coarse gravel using a commercial tamper or any available homemade option. Once done, the final 3 inches to the surface of the gravel driveway should then be filled up with gravel which perfectly matches the colour and texture of the remaining driveway.

✓ Compact the patch. To achieve this in an easy and fast way, simply run your car’s wheel up and down over the repaired spot gently a couple of times. This will be enough to compact the patch and seal the pothole.

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.
