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

how much is a single garage conversion?

Converting your garage into a habitable room can be an option that’s too good to pass up especially when you’re in dire need of more living space in your home. If you’re in a similar situation and considering the cost of a single garage conversion in your home, then you’ve come to the right place! The fact is, the cost of a single garage conversion is dependent on a number of influencing factors which includes your specific plans as well as your location. Generally, the price of garage remodel is expected to cost about half of what you’ll incur when building a home extension or addition from scratch. However, before commencing a project of this magnitude you should put into consideration some things.

A single garage conversion is a huge job which typically involves wall insulation, floor raising, heating addition, cool and ventilation as well as updating doors and windows. Before you get started you should consider if converting your single garage into a room is a good option, whether a permit is required to convert a garage, the type of room a garage can become, does it add value to your home and how much its going to cost.

Just like any other home improvement project, garage conversion cost varies depending on several factors like your garage space specifications. Other factors include the general condition of your garage - the condition of your foundation, walls, floors or roofs, the ceiling and more, planning applications, your location, the services of a structural engineer, internal or external garages etc. According to Santander, the average cost of converting a single garage costs approximately £6,300. However, considering the aforementioned influencing factors we’d expect the cost of a single garage conversion to cost within the range of £5,500 to £10,500.

how much does a loft room cost?

How Much Does A Loft Room Cost

In the event whereby you happen to run out of space in your home and extending sideways or moving out isn’t even a considerable option, the next best solution is to look upwards - the loft. The loft can be converted into a room that can used to satisfy varying purposes, be it a storage room, bedroom, home office, spare bathroom and more. There are a number of loft conversion styles you can go for including a room in loft conversion, dormer style conversion, mansard conversion, or a hip-to-gable conversion. Regardless of your choice, each of the types will not only give you new rooms to enjoy but also add value to your home. However, before getting started, it’s crucial to have an idea of the loft conversion cost to help you prepare a budget and begin planning. Here, you’ll discover the most likely loft room cost for each conversion style you opt for.

• Room In Loft Conversion

This is only suitable for some specific home, but it’s however the most affordable option of the lots. This loft conversion style will cost within the range of £15,000 to £20,000 (prices can be higher in regions where tradesmen are higher in demand such as London and the south east).

• Dormer Loft Conversion

These are relatively simple and straightforward to include in your home. The cost ranges between £31,000 to £58,000 depending on the conversion’s size and other factors.

• Hip To Gable Loft Conversion

This style of loft conversion is more complex than the aforementioned ones, hence they’re usually more costly to complete. The price ranges between £42,000 to £65,000.

• Mansard Loft Conversion

This style of loft conversion is the most complex of the lot and includes a complete overhaul of your loft. The price ranges between £45,000 to £70,000.

• Bungalow Loft Conversion

Any of the main styles above can be done to a bungalow if the planning requirements are fully complied with and if the property is suitable. The price ranges between £30,000 to £70,000.

How much plasterboard do I need?

How Much Plasterboard Do I Need?

Although many people especially contractors have a tough time estimating the number of drywall or plasterboard needed to complete a project, it’s a rather simple task if all factors are taken into consideration. If you’re able to follow the same procedures taken by professionals to count dry wall sheets, you’ll be in the right direction. Let’s have a look at the procedures to follow!

lTake Square Footage Measurement

• Measure the square footage of the area where the plasterboard will be fitted.

• Multiply the height by the width of each wall or ceiling area.

• Add all quantities to obtain a total square-foot amount.

lCalculate Drywall Sheets

• To calculate the number of drywall or plasterboard sheet is very simple once you’ve gotten the total square footage.

• To get started, simply divide the total square footage of area by 32 (that’s if you are using a 4 by 8 sheets) or you can also make use of 48 to make the division (only if you’re making use of the 4 by 12 sheets).

• The answer you get after the division will give you the full number of plasterboard sheets that’s required to complete the project.

We’d recommend you include an extra 10 to 15 percent of whatever you calculate to take care of the possible odd cuts and wastages. This implies that if your total area is 1600 square feet while incorporating 4 by 8 sheets, simply divide 1600 by 32 which equals 50 sheets, now take 10% of 50 which equals 5, then add back the 5 extra to the 50 sheets earlier calculated to get 55 sheets. If you wish to estimate the cost, simply multiply the number of sheets gotten by the price per sheet. Do not forget to include delivery charges and local taxes.

Is a basement conversion worth it?

Whether a basement is worth converting depends on your location and how much work it requires.

A basement conversion can be a great way to add space to your home, and can raise your property value. However, it can also be one of the most expensive ways to do this, so if there’s a possibility to extend your property, or convert a loft or garage, it’s worth considering this first.

You should also compare how much your basement conversion will cost with the amount it could raise your property value by. In some areas, a quality basement conversion could earn you money in the long run, but in others it’ll only cost you. If you’re planning on staying in your property for a long time this might not matter to you, but if it’s not your forever home then it’s an important thing to think about.

Which type of insulation is best?

The best type of insulation for your property will depend on the type of walls and any insulation that’s already present. It’s usually a good idea to have some form of wall insulation as well as loft insulation, as this helps to prevent heat loss in both areas.

how much is a dormer loft conversion?

Are you considering a dormer loft conversion for your home? If yes, then you’d probably want to know how much it costs. Unfortunately, due to the several variables and influencing factors, a precise answer can not be provided for all dormer loft conversions. In this article we’ll give you a vague idea of the general cost so you can set a more realistic budget and start planning.

There are three main types of loft conversion which includes the Velux, Dormer, and Mansard. Out of the three types, the dormer happens to be the most common type and possesses a small flat roofed extension with a window. The dormer loft conversion will usually cost within the range of £25,000 to £30,000.

The price for a smaller dormer loft conversion, mid range dormer loft conversion and large scale dormer loft conversion will be at £2,000 to £7,000, £10,000 to £30,000 and £40,000 to £60,000 respectively. However, you should take note that the prices given are all based on varying influencing factors such as the type of installation that is selected, the type of the rood, en suite conversion as well as other customization. Changes in price can be as a result of the materials required and the extra time per labour that’s needed to complete this home improvement project by the tradesmen employed.

Furthermore, a dormer loft conversion average cost will also depend on the type of dormer you opt for. Here is a list of the most common applications:

✓ Blind dormer loft conversion - £3,200 to £4,400

✓ Recessed dormer - £1,300 to £1,850

✓ Barrel roof dormer - £3,000 to £4,600

✓ Gable dormer - £5,500 to £7,500

✓ Hipped roof dormer - £5,600 to £6,660

✓ Pedimented dormer - £12,700 to £23,100

✓ Flat roof dormer loft conversion - £13,800 to £21,600

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.

do you need planning permission for a loft conversion?

Typically, loft conversions do not require planning permission except in certain situations. They’re usually covered under what’s known as Permitted Development. Certain building works like loft conversion, rear extension and conservatories are granted planning permission by local authorities. Permitted Development, however, gives you a free range to improve your home without having any issues from the councils or regulations. Before your planned loft conversion can be covered under Permitted Development, there are some certain criteria that must be met. This criteria includes the following:

✓ The extension must not go beyond the existing slope of the roof at the front of the house.

✓ The loft space converted must not go beyond 40 cubic metres in a terraced house.

✓ The roof’s height must not be increased by the extension.

✓ The loft space converted must not reach beyond 50 cubic metres in a detached or semi detached house.

✓ The plan for the extension mustn’t involve structures like balconies, verandas or anything other structures of this nature.

✓ The roof extension should be positioned as far back as possible or at least 20cm from the existing eaves.

✓ The side that faces the window openings should be at least 1.7m beyond the floor and the windows should also be obscured.

✓ The roof extension must not overhang the existing roof or wall of the house.

✓ The materials that are to be used must be similar or the same to the materials that has already been used on the house’s exterior.

However, you should bear in mind that there are some properties that are exempt from Permitted Development. Examples of these type of properties include conservation areas, Areas Of Outstanding Natural Beauty and World Heritage sites. Permitted Development does not also provide coverage for listed buildings.
