How much do Builder services cost?

How much do Builders cost? Prices for Builders in 2026 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

What types of cladding are there?

There are two main types of cladding. The first is material cladding, which refers to layers of a material that are attached to the external walls. The material used could be timber, PVC, stone, or other materials. The second type of cladding is rendering, where a coat of plaster is applied to the wall.

Will my extension be expensive?

It depends on the size and type of extension. Small porches or flat roof extensions are very reasonably priced. More substantial two storey extensions can be expensive. In general, the price is roughly proportional to the amount of space you add to your home.

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.

How long does a small extension take?

If you’re planning to build a small extension on your property, you’ll most likely want to know the length of time it’ll take to complete the home extension. Just like many other home improvement projects, it’s impossible to provide a specific number of day in which your project will be completed as the duration is based on a number of influencing factors. This includes the size of the development work as well as whether or not you plan to live in the house when the work is being done. In this article, we’re going to give you a breakdown of the processes that’s involved in building a small single storey extension alongside the duration for each so you can have an idea of how long your small extension project will take. Let’s take a look!

✓ A small single storey extension will normally take about 3 months to be completed.

✓ Site preparation is the first step in the process and it’ll take up to 2 weeks the dig out the footings and prepare foundations. Followed by a further 2 weeks to fit the damp course as well as any drains required around the extension.

✓ The 5th week is spent on working on the external walls and putting in place blockwork to deliver cavity wall insulation.

✓ The next 2 weeks will be spent on installing the roof structure as well as internal walls.

✓ Once done. The builders will make the structure weather proof and electricians or gas fitters will be on site to add power to the extension. This will be followed by internal walls’ plastering as well as breaking into your main house.

✓ After this, when the plaster is dry and decoration completed, units or furniture will then be installed.

how much is a dormer loft conversion?

Are you considering a dormer loft conversion for your home? If yes, then you’d probably want to know how much it costs. Unfortunately, due to the several variables and influencing factors, a precise answer can not be provided for all dormer loft conversions. In this article we’ll give you a vague idea of the general cost so you can set a more realistic budget and start planning.

There are three main types of loft conversion which includes the Velux, Dormer, and Mansard. Out of the three types, the dormer happens to be the most common type and possesses a small flat roofed extension with a window. The dormer loft conversion will usually cost within the range of £25,000 to £30,000.

The price for a smaller dormer loft conversion, mid range dormer loft conversion and large scale dormer loft conversion will be at £2,000 to £7,000, £10,000 to £30,000 and £40,000 to £60,000 respectively. However, you should take note that the prices given are all based on varying influencing factors such as the type of installation that is selected, the type of the rood, en suite conversion as well as other customization. Changes in price can be as a result of the materials required and the extra time per labour that’s needed to complete this home improvement project by the tradesmen employed.

Furthermore, a dormer loft conversion average cost will also depend on the type of dormer you opt for. Here is a list of the most common applications:

✓ Blind dormer loft conversion - £3,200 to £4,400

✓ Recessed dormer - £1,300 to £1,850

✓ Barrel roof dormer - £3,000 to £4,600

✓ Gable dormer - £5,500 to £7,500

✓ Hipped roof dormer - £5,600 to £6,660

✓ Pedimented dormer - £12,700 to £23,100

✓ Flat roof dormer loft conversion - £13,800 to £21,600

Are pumps used for basement conversions noisy?

If your basement has a cavity drain membrane, it’ll need a pump to move water away from the exterior of your basement and prevent flooding.

Sump pumps can be noisy, but they don’t have to be. Generally, if you have a well-designed pump that’s installed correctly, you shouldn’t find it a problem. For best results, hire a skilled, experienced professional to supply and install your drainage system.

how much to board a loft?

How Much To Board A Loft?

If you stay in a building where the space meant for storing stuffs is not sufficient, boarding your loft may be just the perfect solution for you. In several homes, the space is already present, and all you have to do is to make it more usable by boarding it out. This is unarguably one of the easiest and quickest ways to create storage space in your home.

Boarding a loft comes with a number of special benefits which includes:

• Assisting to declutter our living spaces and makes for a more spacious home.

• Creating a usable space whereby all seasonal items can be stored.

• Assisting to reduce heating bills as it prevents the loss of heat. When your loft is well boarded and insulated, it’ll help trap heat and prevent it from escaping via the roof.

• Adding to your home’s value by making your attic a very useful space for storing items.

• Helping to create a quiet space which can used for relaxation or getaway purposes and of course, this will require a bit more structural work.

So now that you’ve learnt a few of the benefits associated with boarding a loft, how much will it cost to have one made? This depends on an array of factors which includes the size of the space needed, the type of materials and labour cost.

Overall, a standard semi detached building will feature a lot of space of about 40 sqm to 50 sqm in size. There’ll be a need to add to the height of the floor joists before installing the chipboard decking boards. This job size should cost within the range of £1,000 to £1,500. It’ll require just a two-person team that are fully equipped and well versed about the processes.

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.
