How much do Builder services cost?

How much do Builders cost? Prices for Builders in 2025 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

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.

What are the benefits of cladding or rendering?

The main reason that people use cladding or rendering on their property is the aesthetic benefit. These materials can really boost the appearance of a home. Cladding and rendering can also increase the thermal performance of a property. Speak to a specialist to find out whether your property will benefit.

Have you decided to improve your property instead of moving? The common problem most homeowners face after deciding to embark on a home extension project is not knowing where to start. In this article we’ll walk you through everything you need to consider and put in place before commencement of your home extension project.

• Is the extension worth it?

Before breaking the bank, you must be sure that the project will add good value to your home. In terms of “value, this is not only limited to the financial gain after disposal of the property, but also several other juicy benefits to be derived from extending your home like an extra living space for the household to spread out and more.

Check with your local authority to determine whether or not you’ll require to submit an application. You can also consult a building expert like an architect for advice.

You have to decided whether you’ll hire a professional architect to design the extension or not.

• Who will manage the building work?

If your home extension project is designed and built by a professional company, they’ll be responsible for the management. However, if you decide to use an architect or designed it yourself, you’ll have to hire a main contractor to manage the build.

• How to set the budget?

There are so many factors that can affect the cost of an extension, so it’s better to get the costs from your builder before proceeding.

• Do I need yo inform my home insurance firm?

Absolutely! This is very important as the new extension may affect the rebuilding cost of your property which could have an impact on the policy premium.

• Do I need to inform my neighbours?

It’s very important to discuss your plan with your neighbours before applying for a planning permission and communicate about the concerns they might have.

The outcome is a flat roof space which enables the fitting of full sized windows as well as the incorporation of several appliances.

The average cost of a standard dormer loft project will range between £25,000 to £50,000.

how to tile a porch roof?

Tiling a porch roof is a very important but laborious and difficult task. A project of this magnitude will require a large investment in planning and preparation way before the actual installation process takes place. It can be a brand new porch roofing tile or a replacement of the existing one, either way it’s crucial to get the right technique. If you lack proper training or experience in this field, we’d recommend you hire the services of a reliable professional probably within your local area to guarantee the best results and to save yourself some time and money. This guide will give you a good insight into the porch roof tiling process. Let’s have a look!

• With the crown looking upwards, put the first tile on the batten and centre the tile from side to side.

• Hammer a 10d nail at the base of the tile and into the batten (make sure not to overdrive the nail).

• To provide a much needed support, apply a little mortar under the first tile.

• Identify the inner end of the first tile and place another tile on top. Take a measurement from the outer end and adjust the end of the second tile to fit.

• Just like you’ve done with the first tile, nail the second tile into the batten.

• Position two tiles at the both ends of the ridge and proceed with the installation just as you’ve done with the previous tiles.

• Take a measurement of the distance across the ridge from the first tile’s outer end. Once done, you can then calculate the number of tiles required by subtracting 16 inches from your measurement and divide the answer by 8.

• Beginning at the second tile on one end of the ridge, install the half the number of ridge tiles towards the centre of the ridge. Now install the remaining tiles working from the opposite end to the ridge’s centre. At the centre of ridge should be a key tile with mortar.

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.

how much to re render a house?

Rendering of a house is one of those projects that can greatly improve the visual appeal of your home, enhance it’s energy efficiency, protect the brickwork from the elements and ultimately, add value to your home. Generally, the cost of rendering a house normally costs within the range of £25 to £70 per metre square, while the average cost house rendering costs stands at about £40 per square metre. Therefore, a 3 bedroom semi detached house will cost within the range of £4000 to about £5000.

The total cost of rendering a house is determined by a wide range of factors. These factors includes the following:

✓ Type of the rendering. There are three main types of rendering which includes sand and cement rendering, monocouche rendering as well as acrylic or silicone rendering. However, re-rendering applies to sand and cement sooner and it’ll also have to be painted every 3 to 6 years. Consequently, longer term cost can be higher when compared to the other types.

✓ Ease of access. Where your contractor will have to work around obstacles like shrubs or conservatory, this can make the cost a bit higher as it’ll take longer time to complete.

✓ Prep work. If the contractor needs to fill some cracks or perhaps an old mortar requires tuck pointing before rendering can be started, this will also affect the cost.

✓ Scaffolding. In the event whereby the job requires the use of scaffolding and you’ll have to hire one as a different cost, then the price will be higher.

✓ Your location. Due to the high standards of living and higher demands in areas like London or the Southeast, prices in these regions are usually higher than that of the other regions like Midlands and North.

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.
