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 is a hip to gable loft conversion?

This is a type of loft conversion that extends your roof on the sloping side. It is a great option to go for especially where a hipped roof effectively makes the usable floor area a lot smaller which can be a tricky affair when it comes to putting in a new staircase. Here, the roof is extended from the current ridge in such a way that it effectively fills the gap between them. As a result, this turns the hip (in a hipped roof) into a gable to create space in your roof for a loft conversion - hence the name “hip to gable.

The new gable can be done in whatever way that suits both your taste as well as your property. You can make the new gable construction in woods and then tiled to match your existing roof while you can also go for other options such as brick block pebbledash or rendering. You are also free to fit in a new window into the loft conversion end so as to allow for natural light into the loft space.

A hip to gable loft conversion is mostly found on both semi detached and end terrace buildings, particularly those constructed in the 1930s. Overall, this type of loft conversion is particularly ideal for homes that features a hipped roof and with a sloping roof at the side of the property. Some detached properties can also possess a hipped roof on the side - and as such, a double hip to gable loft conversion can also be deal as it’ll create more loft space for usage. If your home fits into the bill, then you should be aware that once the project is completed, you’ll have plenty of usable space available to both you and your loved ones.

how much value does a loft conversion add?

When its impossible to build out and create more space sideways, why can’t you look upwards? As more and more homeowners in the UK are carrying out their loft conversion project, one question that keeps popping up is the amount of value the loft conversion can add to their homes. However, this is a question that is impossible to provide a single and precise answer to. This is because the value that’ll be generated by a loft conversion is largely dependent on a wide range of influencing factors. To give you a vague idea of the loft conversion value to a property, we’ve put forward a research carried out by industry experts so you can know what you’re in for.

Nationwide carried out a research which shows clearly that a loft conversion including an additional bedroom as part of the building plan will increase a house’s value by up to 21 percent. Since the number of rooms a house has is one of the main metrics for house valuations, loft conversion comes in pretty handy as it’s a great and easy way to convert your house from a 4 bedroom house to a 5 bedroom house prior to sale.

Apart from the financial value aspect, loft conversion also adds more value to your lifestyle which is very unlike nearly other financial investments you can make. More space in your house automatically means more storage or a new room as you wish. A new room can be for a growing family or probably to serve as a guest room. It can also be used as a study space or even an office especially with the rapidly growing rate of people working from home. With loft conversion, the possibilities in terms of value are simply endless!

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.

does a kitchen extension add value to your house?

If you’re planning to add a kitchen extension to your property or perhaps you’re simply looking for ways to increase the value of your property, this is one of the common questions that usually pops up. A simple answer to this question is yes, a kitchen extension will add value to your house. With a kitchen being one of the most frequently used room in a house, adding an extra space to the commonly used room can only increase the value of the entire property. However, to determine the value added by such an extension, there’s a need to calculate the cost of setting one up first.

Kitchen extension costs are greatly influenced by a wide range of variables such as the size, type of the extension and specifications, your location, professional fees, materials used and more. Overall, the type of the extension you opt for will play the most significant role in the determination of your kitchen extension cost. Here, we’ll be looking at a single storey kitchen extension.

For a single storey kitchen extension, you can expect your home’s market value to increase within the range of 5 percent to about 10 percent. When trying to calculate the cost of kitchen extension, it’s crucial to take into account how much value it’ll add to your home so as to make sure that the amount expended will not outweigh the expected value to be added by the project.

For a more accurate idea, there’s the need to consult local estate agents. However, for a much needed guideline, single storey kitchen extensions are usually able to add about 5 to 10 percent to a home’s value, while double storey extension should be up to 20 percent. But as stated earlier, this will depend on several variables.

Will my garage conversion cause disruption to the rest of the house?

It shouldn’t do. Most companies will do all the interior work first, and the last job to do will be creating the opening from the house to the conversion. A reputable company will make sure they cause as little disruption as possible during this time.

Can cladding help with a damp problem?

External cladding will have an impact on a damp problem. However, it’s important that cladding is the last part of a damp treatment, as installing cladding over a damp wall will make the problem worse. Do not cut corners or try to remedy a problem with the cheapest solution, a damp proof course may need to be put in place before cladding.

How to cut plasterboard?

Cutting a plasterboard is a relatively simple process requiring only some basic tools. Unfortunately, the lack of knowledge serves as big deterrent for many people who wishes to put it to good use. Plasterboard can actually be sawn using an ordinary timber saw that’s fine-toothed to get a cleaner edge. However, the basic tools you may also need includes a sharp knife (Stanley Knife), pencil, a fine sandpaper, a straight edge and measurement tape as well as a wall board saw. Let’s have a look at the cutting process!

• Firstly, you need to put the plasterboard sheet flat on a firm surface.

• Use the tape measurement to measure the cut you wish to make.

• With the help of a pencil, simply mark out the part you wish to cut on the plasterboard’s front side.

• Once marked, place a spirited level over the marked spot on the plasterboard sheet you want to cut.

• Cut a shallow mark into the plasterboard sheet using the Stanley Knife to cut along the edge.

• The cut should be slow and gradual to ensure you do not wander off the edge of the marked area.

• Once the shallow cut has been made, turn the plasterboard sheet on its edge and deliver a quick and sharp push towards the plasterboard’s back and on one side of the cut.

• Place the plasterboard sheet backing against a flat surface ensuring the line of the cut is over an edge. Once done, give a quick and sharp push towards the back of the plasterboard sheet and on the part of the board is reaches beyond the edge.

• Using a fine sandpaper, remove all forms of paper burrs.

The process of cutting plasterboard requires a lot of practice. If you lack the training and experience, the cutting process is best left to a proficient professional who can guarantee the best results the first time and save you some additional costs due to potential damages.

what is rendering on a house?

Rendering is an external wall’s plastered finish which provides a smooth finish while also protecting the brickwork from the elements like rain, snow and the likes. The traditional rendering is normally applied in two or three coats which enables it to be more resistant to surface cracks. In modern times, the finishes are largely different from the grey pebble dash of post war housing. Today, we now have a plethora of specialist products to pick from such as through-coloured silicone renders as well as one coat renders. The types of renders include the following:

✓ Cement renders. These are the common option that are usually mixed on site and used in a number of applications, then painted when dried. There’s a need to paint this type of render regularly to keep them looking great.

✓ Polymer renders. These are pre mixed and mostly pre coloured (usually with through colouring).

✓ Through-coloured products. These rendered do not need to be painted as the pigment is already added in the manufacturing process to colour the whole render.

✓ Lime renders. These are superior to cement as they’re less likely to trap moisture in the brickwork and also more good looking. However, they’re generally more costly and more difficult to apply.

Overall, rendering on a house provides several benefits. Not only is it able to protect your brickwork against the elements like the rain and wind, but it can also make the building more efficient. Being fully aware that about 30 percent of the energy used in heating a home is lost via the external walls, making use of a product such as acrylic insulated render is a smart approach to improve your home’s energy efficiency without affecting your interior living space.
