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

how much does it cost to have loft boarded?

How Much Does It Cost To Have A Loft Boarded?

More often than not, several homeowners fail to realize there’s so much value sitting right under their roof - the loft. When a loft is boarded, there are so many juicy benefits that can be derived. It can be used as a storage room, spare bathroom, home office and several more functions. Therefore, if you really wish to maximize the space under your home’s roof, you’d have to considering boarding it. So how much would it cost to have your loft boarded? Here, you’ll discover the cost of boarding your lofts so you that you can set a budget and start to plan.

The cost of boarding a loft is actually affordable for several individuals, simply because you’re allowed to floor as much or as little as you require. And while you’re up there flooring and fitting the loft boards, you can as well decide to upgrade the insulation of the loft too. This way, you be able to prevent heat from escaping through the roof of the house which helps improve energy efficiency and ultimately, save you some money on heating bills.

If you’d prefer to make it a DIY project, the cost of 18mm chipboard is about £8 to £10 per sheet sized 2400m x 600m. Meanwhile the insulation boards should range between £18 to £22 for a sheet.

For a professional service, you’ll be provided with a quote for both the materials and labour. The amount will be based on the number of boarding required as well as the method selected. For an average storage space needs, flooring size of about 15m2 is suitable. The price for this quantity would be between the range of £50 to £700 for the counter barren method or above £1000 for a more sophisticated method.

can you render a house in winter?

Aside from the cold weather not being the most pleasant condition to work in, the winter weather can also cause a lot of problems for construction workers and even more so when you’re working with render. Poor weather conditions can generally cause a lot of harms on the final finish of a render. Below are some of the reasons why you should not consider rendering in a bad weather.

✓ Lime bloom. Render can be impacted by lime bloom as they are subjected to damp conditions and low temperatures while curing. This is due to the fact that cement are intolerant to slower drying conditions especially immediately affect its application.

✓ Top coats can be compromised. Coating are likely to get washed off before they’re even afforded the chance to set if drying conditions are low.

However, because its cold out there doesn’t necessarily imply that work must stop. It’s very possible to render during the winter months but to avoid potential pitfalls, we’ve got some tip that can be of great help. Let’s have a look!

✓ Check the weather forecast. Determine the drying and curing time and watch the forecast for the temperature dropping at night.

✓ Select the most suitable render. There are renders that are suitable for application in low temperatures to about 5℃ or even as low as 1℃. These types of render are fast setting which makes them perfect for the cold condition.

✓ Watch out for frost. Frost and render are enemies. Therefore, it won’t be wise to work with frosted materials, on frosted subtrates or apply below the recommended temperature that’s written on the product’s datasheet.

✓ Protect the finish. Make use of artificial enclosures around the scaffolding to battle adverse weather conditions.

How do I know if I have cavity wall insulation?

With cavity walls being very similar to other type of brick works, it can be quite confusing to figure out the type of wall your property possesses. If your house was constructed after the 1920s, then its highly likely the you have cavity walls, while older houses (houses before the 1920s) are likely to have solid walls. What’s more? If you happen to own a home that was built in the last decade, then it’s very possible that it was built with insulation installed during construction.

An effective way to determine whether or not your property is built with cavity wall is to examine the brickwork on your home’s exterior. The bricks will typically possess a regular pattern if it features cavity walls. In the event whereby the brick work is covered by render, you can also figure it out by taking a measurement of the wall’s width. If the brick wall is beyond 3000mm in thickness ( from the exterior wall to the interior wall), then it probably features a cavity. Meanwhile, a wall that’s narrower is very likely to be solid. Stone walls, on the other hand, may actually be thicker but are most times solid.

In a situation whereby your house is built using steel frame or timber frame, or made using pre-fabricated concrete, there are varying rules that applies when it comes to insulation and should be examined by an expert before any insulation is installed. More often than not, most contractors will have installed special air vents, which can also be a good indicator that a cavity wall insulation has been done.

how deep do footings need to be for a porch?

No matter how big or small a building is, it can only be as good as it’s foundation - and that’s a fact! It all starts from the footing and when it isn’t deep enough, unlike badly installed gutters or gapped hardwood flooring, can make the whole building collapse to the ground. Just like any code recommendations, the depth of the footings of your porch is a parameter that must be complied with and adjusted to suit your local code requirements.

As a rule of thumb, you should always dig below the frost line when excavating your footings. At this depth level, the moisture present in the soil will be frozen. Ultimately, this will help the ground to act as a barrier to insulate the soil below the footing from freezing during the cold months. As a result, in regions where the weather is almost always very cold the depth of your footings is expected to be at least 48 inches. But in areas featuring a warm climate, you may be allowed to install your footings on grade.

In addition, it’s compulsory that your footings must be installed at a minimum depth of 12 inches below unsettled soil. However, if you’re constructing the structure into a steep hill’s side or by the side of a retaining wall, it’s required that you maintain the least distance to grade both vertically and laterally. In the event whereby you need to achieve a good lateral barrier, you’ll need to have your foundation dug a lot deeper compared to if it’s on a flat surface. For a more accurate and updated information, you can consult your local building inspection department to get familiar with the requirements in your area.

What kinds of loft conversion are there?

There’s a huge range of different types of loft conversions. The most common are dormer and skylight or Velux conversions. There are also hip to gable and mansard conversions. The type of loft conversion that’s most suitable for your property will depend on the style of roof and the size of your loft.

what is a garden room extension?

They are typically semi-glazed building that features a tiled roof rather than glass.

Overall, if you’re looking to create an additional space in your home without having to break the bank, then garden room extensions may be your best bet.

when do you need planning permission for a house extension?

If you’re planning on adding a house extension to your property, you’d probably be worried about whether or not your proposed extension would require a planing permission. Well, it may be relieving to know that not every house extension project would require a formal consent, and in fact, several extensions are covered by the permitted development rights. Not only can this save you a considerable amount of time especially at the project’s planning phase, but it’ll also save you money on the application fee. In the UK, single storey extensions to the house’s rear can be 3 metres deep for both semi detached houses and terraces or 8 metres deep for detached homes.

So how do you know when you’d require a planning permission for your home extension? Well, if your extension plan fits these criteria explained below, then your project is most likely going to be allowable as a permitted development.

• Extensions, which includes previous additions, must not go beyond half of the original house’s total surrounding land area.

• The main elevation, or side elevation where it fronts the highway, must not be extended forward.

• For single storeys, the rear additions must not extend more than the original house’s rear by more than 3 metres in both semi attached homes and terraces (4 metres for detached houses).

• Extensions to the side must be a single storey with a height not exceeding 4 metres and not going beyond 50% of the original house’s width.

• Extensions hat within 2 metres of a boundary should have a eaves height not more than 3 metres.

• Multi storey addition must not extend beyond the original house’s rear wall by a maximum of 3 metres or 7 metres of the boundary opposite the rear wall.

• Permitted development rights do not apply in listed buildings or designated areas.

do i need planning permission for a loft room?

Do I Need Planning Permission For A Loft Room?

The answer to this question is maybe. Generally, loft rooms are covered under “Permitted Development which means you won’t need to apply for a planning permission to build a loft room. This is like an advance planning permission provided by local authorities to allow some particular building works to be done such as loft conversions, rear extensions and more. When you’re covered by a “Permitted Development, you’re given the free range to oversee your home’s development without much interference from the regulations or the council. However, for permitted development to apply, there are some specific criteria that must be met. Therefore, if your loft room does not meet the following requirements given below, then you must complete a planning application before proceeding.

• In a terraced house, the converted loft space must not be more than 40 cubic metres.

• In a detached building or semi detached house, the converted loft space must not be more than 50 cubic metres.

• The existing roof slope at the front of the house must cover the extension made.

• The extension should not increase the height of the roof in any way.

• Verandas, balconies and any other structures of this nature must not be included in the extension’s plan.

• The side facing window openings should be at a minimum of 1.7 metres above the ground. The windows must be obscured as well.

• The roof extension should be set back as far as practically possible. It should be at a minimum of 20cm from the current eaves.

• The roof extension should not overhang the house’s roof or it’s wall.

• The materials to be incorporated must be the same or at least similar to what you already have on the house’s exterior.
