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

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 much is plasterboard?

How Much Is Plasterboard?

Do you wish to install plasterboard in the nearest future? If yes, then you’d probably want to know the amount it’s going to cost. Here, we’ll give you a detailed plasterboarding prices breakdown to help you calculate an estimate for your project.

A plasterboarding project including the cost of both materials and labour with the use of a high quality panels is about £4 to £5 per panel. Therefore, if you wish to calculate on the basis of a standard room about 12x12ft would cost about £500 to £600. However, this price can fluctuate significantly depending on the professional as well as the quality of the materials you wish to incorporate in completing the project. We’d recommend that you hire the services of a professional with accreditation as he would provide you with a detailed quote with no hidden charges or costs. To give you a clearer idea, we’ve taken the time out to put together some estimated costs of employing the services of a seasoned professional plasterer to supply and plasterboard your home or office. Let’s take a look!

• A 6 x 12ft room with panels and plasterboard should have an average cost within the range of £250 to £400 and duration of one to two days.

• The individual cost of plasterboarding or drywalling a standard 12 x 12ft room should have an average cost within the range of £500 to £600 and duration of one to three days. These includes 60% for materials used (£330), 30% for tradespersons (£165) and the remaining 10% for waste removal (£55) to give a total cost of £550.

• A 12 x 24ft room with panels and plasterboard should have an average cost within the range of £1000 to £1200 and duration of three to six days.

how much is a loft conversion?

With the ability to add approximately one third of your existing living space ( by converting your old, unused attic) to your home or property without having to let go of your garden, it’s quite easy to see the reason why loft conversion has rapidly grown to become one of the most popular home improvements in the UK. However some homeowners usually shy away from the idea simply by looking at the perceived high cost of carrying out such a project, despite several researches showing that loft conversions offers the best rate of return on initial investment when compared to the other home improvement projects. So exactly how much would it cost to carry out this project?

Just like several other home improvement projects, the cost of a loft conversion varies greatly depending on a wide range of influencing factors. These factors include the size of your home, how old your home is as well as the quality of the fixtures and fittings you want to install. For instance, a high end bathtub alone can cost you thousands of pounds, meanwhile you can also construct a full bathroom suite on just a couple of hundred pounds. However, to give you an idea of the minimum cost of a loft project we’ll look at the most popular types and the minimum cost of each.

✓ Internal Loft Conversion - The most affordable type of loft conversion tends to start from £25,000 and above.

✓ Dormer or L-Shaped Dormer Loft Conversion. These are the most popular types of loft conversion. Dormer price tends to start from £35,000, while the L-shaped dormer starts from £45,000.

✓ Mansard Loft Conversion - This involves replacing the entire side of a sloping roof with a vertical wall and flat roof. It requires a planning permission. The type of loft conversion usually starts from £45,000.

✓ Hip To Gable Loft Conversion - This usually starts from £50,000.

Does cavity wall insulation lead to damp problems?

Insulating a cavity wall should not affect the damp proofing of the wall. All insulation approved for use in cavity walls has been tested to ensure that it does not allow damp to pass through the wall. Some walls which receive a lot of wind driven rain are unsuitable for cavity wall insulation.

Will insulation save me money on my energy bills?

This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.

does a single storey extension add value to your house?

Does A Single Storey Extension Add Value To Your House?

When you’re looking to construct a single storey extension or perhaps you’re just searching for means to increase the value of your property, this question always pops up. The short and simple answer to this question is a resounding yes, a single storey extension can go a long way to increase the value of your property. Just like any other home improvement, when done right, adding a little extra living space is one of the top things you can probably think of that’ll provide a cool increase in your property’s value. However, before you rush in you must also take note of some factors so you can be certain a single storey extension is the right option for you. These factors include the quality of the build, complexity of the build, cost of the build versus the value gain, ceiling price in the area, finance costs as well as the inconveniences and stress.

Generally, the average cost of a single storey extension can range from £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. So it’s important to know the value they’ll add to your house before deciding to make such an investment.

The value added to your property will depend largely on the quality and size of your single storey extension. The value is usually calculated by estate agents using the number of bedrooms, bathrooms as well as the floor area. Inside London, it’ll typically be priced at £5,000 to £10,000 per square metre, while outside London should be within the range of £900 to £2,000 per square metre.

How to convert a basement into living space?

The best way to go about converting a basement depends on its current condition and what you’d like to use it for.

If you’re happy with its size and structure, and just want to turn it into useful storage space, then your project shouldn’t be too complicated. You’ll simply need to make sure it’s damp proof and waterproof – either by fitting tanking or a cavity drain membrane with a sump and pump. You may also need to invest in new flooring, fit basic lighting, and plaster and paint the walls and ceiling.

If you’d like to turn your basement into living space, then you’ll need to think about ventilation, insulation and heating. If this involves creating a kitchen or bathroom, you’ll also need to incorporate plumbing.

If you want to extend your basement, add lightwells, or fit windows and a sunken garden, this makes things much more complicated. You’ll probably want to hire an architect or basement conversion building specialist to help you with the design and planning, and you’ll need a structural engineer to help you ensure your property is sufficiently supported.

how to lay loft boards?

How To Lay Loft Boards

Do you need more storage space in your home or property? If you live in a tiny space especially where extensions can’t be made sideways, why not look to the topmost area of your home and consider boarding out your loft to make it usable?

Boarding your loft can make for a fairly easy DIY project but like every other home improvement tasks, it requires some specific skill sets as well as knowledge for a successful construction. Therefore, we’d recommend you hire the services of a reliable professional in order to guarantee the best possible outcome, especially if you lack proper training or experience that’ll help you avoid some costly mistakes. Here, we’ll give you a good insight into the loft board laying procedures.

• Get The Right Tools & Equipment

The materials and supplies you’ll need to lay loft boards include loft boards, screws, tape measure and pencil, drill, hammer, saw, protective gear such as gloves and dust mask.

• Work Out The Area

Measure up the area you need the boards to cover. The standard loft features two different sizes (both are 18mm thick) which include 2400mm x 600mm and 1220mm x 320mm. You should ensure that the board you opt for fits through the loft hatch perfectly.

• Start Laying

Once you’re done working out the area, the next step is to put on your protective gear and start putting the boards in place. You should lay the boards in a staggered pattern so as to give a better strength. While doing this, watch out for any wire running through your loft so they don’t get trapped, you should also cut the boards for easy access to the light fittings’ top.

• Make It Permanent

Upon the successful placement of the boards in a way that offer a safe area to store things and stand on, you’ll have to screw them in place. Start by drilling 2 or 5 holes along the edge of individual boards in such a way that lines up with the centre of the joist below. Once done, then you can fix them in place with screws.
