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 a builder cost?

With the prices of buying a house skyrocketing, many of us are tempted to building our own house. This is sometimes an excellent choice, but you will first need to understand the costs of building a house from scratch. As per a general estimate, the cost of self-build ranges between £300 per m2 to £3,000 per m2.

As you can see, this is quite a variation in price from lowest to highest. Location is a prime factor in determining the costs. Building a house in London and the South is more expensive compared to other regions. Aside from location, several other factors make up the price.

Self-manage with subcontractors

You hire professionals directly like builders and carpenters. You also buy all the materials yourself allowing you to get the best prices.

Hiring a main contractor with other subcontractors

You will first need a main contractor who will help to create the watertight structure for your house. For the rest of the work, try hiring out subcontractors. Make sure that you buy all the materials yourself to get the best price.

External cladding materials

If you are looking to install other external material other than brick, you will also need to factor in the cost for the same.

Here are some example prices:

• Render on blockwork costs around £25 per m²

• Timber cladding is around £25 per m²

• Hand¬made all-weather tiling costs around £54 per m²

• Rubble walling or flint is around £90 per m²

• Reconstituted stone costs about £48 per m²

• Natural stone is about £75 per m²

Make sure to include these costs when coming up with the estimate.

Roofing materials

Non-standard roofing materials tend to add more to the cost and therefore you will also need to account in for this factor.

Here are some examples:

Welsh slate – £60 per m²

Second-hand slates – £35 per m²

Handmade clay tiles – £65 per m²

Reed thatch – £80/m²

If you choose to add any unique material to your roofing, be sure that you remember to factor in its cost.

do you need an architect for a garage conversion?
Have you decided to convert that under-utilized space ( garage) in your home to a more habitable space where you can do anything asides general storage or parking a car? If yes, then you’d probably want to know where to start or if you’d require an architect to get started. Well, you’re not alone! This is one of the most frequently asked questions when it comes to garage conversions and reasonably so. Talking about where to get started, when it comes to home improvement projects the first step to take is determining whether or not you’d require a planning permission or if your proposed garage conversion is covered under permitted development rights. Once you’ve been able to conclude on that, the next step is deciding whether you’re going to complete the project yourself, hire the services of tradesmen or employing a builder. And this ultimately brings us to the question of whether you’ll need an architect for a garage conversion. To get started, it’s highly recommended that you employ the services of a professional architect or an architectural technologist to assist in designing your garage conversion. However, most garage conversion projects are straightforward with no complex changes to be made so far you wish to avoid applying for a planning permission and staying within the set guidelines of the permitted development rights. In such events, if you’re properly trained and well experienced in the field, then it may be cost effective to design your garage conversion by yourself. It should, however, be noted that it all depends on your personal preferences and budget. If you’re on tight budget and don’t mind a straightforward design, you can save cost by not hiring an architect.
can i build a room in my garden?

The short and simple answer to this question is yes, you can build a room in your garden. In fact, if you want an additional space for a living room, dining room, games room, study room or perhaps you want something as cool as a pool house, then looking at your garden for a solution may just be the perfect answer to your need for an extra outdoor living space.

Outbuildings such as garden rooms do not usually require planning permission as they’re usually covered by the permitted development. As a result, making it even a lot more attractive to homeowners who would not like to pass through the stress involved or pay the money required to submit an application for planning permission. However, if you need your garden room to be covered by permitted development ( if it’s not a listed building or in a designated area), you must follow these guidelines:

✓ The garden room shouldn’t be in front of your home or property.

✓ The total area of your extensions, sheds and outbuildings ( which includes your garden room), must not go beyond 50 percent of the total land area surrounding your property.

✓ It must be a single storey that’s less than 3 metres high ( 4 metres for a dual pitched roof). And it must not go beyond 2.5 metres in height if the structure is within 2 metres of your boundary.

✓ The eaves must not go beyond 2.5 metres above ground level.

✓ It must not feature a balcony, veranda or any raised platform

✓ It must not be a self contained living accommodation.

The position of your garden room will be partly determined by the space available in your garden. If you need it to link it to your utilities then positioning it a bit close to your main house would be a cost effective choice unless you’re using off grid sources of power, heat as well as water.

how much does a two storey house extension cost?

If you’re considering adding a two storey house extension, then setting a budget for this project would be a great way to get started. Similar to a rear extension, a two storey extension usually leaves the rest of the building needing some work and, due to its size, this may imply the re-development of the entire house - which is why they can be very costly. Some of the other influencing factors that can have big impact on a two storey house extension cost includes: your location, the size of the build, complexity of the design ( anything beyond the standard build will normally require more expertise and time), the glazing to be incorporated ( the more the glass used in the project, the more the material cost), as well as the team used.

Generally, when it comes to extensions, the major part of the expenses will be made on the build of the project. This is because it doesn’t only cover the material cost but also the contractor’s overhead as well as the daily rates. At this stage, the extension prices can be determined by the standard of the work that’s being done.

For a fairly average room size of about 18 square metre, the two storey extension should cost within the range of £2,500 to £3,000 per square metre - with the range being determined by the finishes incorporated. Therefore, a two storey extension of about 18 square metre should cost within the range of £45,000 to £55,000. However, this is with the assumption that there are standard window sizes, bathroom suits are modest, and without any need for any purpose joinery or glazing. If you wish to include all these extra features you’ll also have to pay more to make the total cost between £70,000 to £80,000.

Will external wall insulation stop condensation?

Damp issues on a property are usually generated by a lot of factors such as a poor or broken guttering, condensation and lots more. The question arising here is what is the possibility of External Wall Insulation (EWI) preventing condensation? Not only is EWI a reliable way to reduce condensation-caused damp, but it’s also one of the major reasons property owners in solid wall homes consider thermally rendering or cladding their external walls.

Condensation arises as a result of warm moist internal air hitting a cold surface such as the steaming up of both windows and mirror when having a shower. What happens here is the condensation of the water vapour in the air from a gas to liquid in the process of touching the cold surface - one whose temperature is significantly reduced to reach the dew point. At the dew point, condensation is very rampant, and to tackle this issue you’ll have to heighten the wall temperature in order to convert the moisture to vapour and permit it to pass through the wall. And that’s exactly the job of an external wall insulation!

To get started you must ensure that the walls are clean and dry prior to fitting the external wall insulation. The month of May through to September when the weather tends to be dry and more stable are usually the best period to carry out the project. The external wall insulation will function just like a cosy blanket around the building. Ultimately, changing the feel and temperature of the inside of your home. As a result, the previously cold walls will no longer be cold which goes a long way to mitigate the effects of condensation. Furthermore, when an EWI is installed, the rooms of your home will automatically trap more thermal mass as the heat is saved in the walls’ fabric and released back when the temperature drops.

how to pebble dash a wall?

Pebble dash is an effective way to tune up your house or property as it can go a long way to enhance its curb appeal while also add to its resale value if you should decide to sell later on. Although, it’s highly recommended to leave this task for a reputable specialist, it’s also something that can be done as a DIY task. It must be states that this is a pretty difficult job and even more so if you haven’t attempted it before. In this post we’re going to take you through the processes involved in pebble dashing a wall. Let’s take a look!

  • Mix up water with the lime strictly following the manufacturer’s instructions. Once done, leave it covered up to hydrate for at least 24 hours.
  • Take one part of the slaked lime and mix it up with cement and six parts sand. This is to give the base mixture required to spread onto the surface.
  • Use a trowel to apply the mixture onto the wall. Ensure that the trowel is level and use the edges to make a flat and smooth layer of the mixture on the surface as a base layer. Allow the base layer to dry for up to an hour. Then, rake the surface using a notched trowel and allow to dry for a minimum of 24 hours.
  • Rinse and drain your pebbles. Then, set them under the wall you’re pebble dashing.
  • Take the top coat of five parts sand and mix with one part cement and one part slaked lime. Use a trowel to apply this mixture over the base layer and smoothen it with the trowel to create a flat and even top layer.
  • Spread a plastic sheet beneath the wall you’re pebble dashing to capture any loose pebbles as they fall.
  • Grab the bucket of pebbles below the wall and scoop some of the pebbles up using a scoop or trowel. Some will stick and some will fall into the plastic sheet already placed below. Continue throwing the pebble dash until the surface is completely and evenly covered with pebbles.
  • Lightly press and fit the pebbles on each section into the wall and leave for at least 24 hours to dry.

what is a garden room extension?

A garden room extension, also referred to as Sunroom or Solarium, is basically a stand alone garden building that’s totally detached from the home. They are typically semi-glazed building that features a tiled roof rather than glass. What would have been good examples of garden rooms extensions include conservatories, orangeries as well as pool houses, however they are constructed with the help of different materials and features which ultimately makes them different to garden rooms.

Garden room extensions are built with the major purpose of adding extra functional living spaces for a wide range of room options such as a second living room, dining room, study space, home garden office or a rehearsal space - the options are numerous. In other words if you’re looking for an additional usable space within your home or property, a garden room extension can be designed to suit your needs. So whether you need comfy sofas for evening relaxations, a sturdy office desk for work or large dining room table for dinners with family and friends, a garden room extension can be all that you need to achieve to your living space goals or just to add more value to your property.

Garden rooms extension has multiple alternatives such as a conservatory, garage conversion, loft conversion, extension and garden rooms. However, it has some great benefits over its alternatives. These benefits include, being very cost effective, hassle free, can be built within 5 to 9 days, rarely requires planning permission, does not require building regulations approval, includes a full professional installation and management without any need for subcontractors, modern and unique as well as being very versatile. 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.

how much to render a house?

Rendering a house’s external walls is one of the cheapest and most effective ways by which a building can be made waterproof and also good looking. If you’re thinking about rendering your house, figuring out the cost of completion is usually one of the most important things you’ll have to consider before you proceed and if you don’t know where to start, finding an experienced tradesperson who possesses several years of experience as well as the ability to overcome the different issues that he may be faced with while on the project is paramount. If you’re able to get one, however, you should know that they rarely come cheap.

When trying to determine the accurate house rendering cost estimate , a tradesperson will put into consideration a great number of factors. Even at that, a rough estimate still requires both skills and expertise to be able to take into account all the necessary factors. In general, a typical 3 bedroom home in the UK will cost within the range of £4000 to about £5500 for a complete render job on the outside and covering from top to bottom.

Usually, the most important factor which play the biggest role when determining rendering costs is the area that’s going to be covered by the render mix. Professional contractors will provide a quote based on the rendering costs per square metre. Below are some rough estimates of rendering costs of properties depending on their size (without VAT).

✓ For a small mid terrace house of about 40 to 50 square metre, the total rendering cost estimate is £3000 to £4000.

✓ For a large mid terrace house of about 70 to 180 square metre, the total rendering cost estimate is £3000 to £5000.

✓ For a three bedroom detached house of about 100 to 160 square metre, the total rendering cost estimate is £4000 to £5500.
