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

What types of work does a builder do?

Any residential building work requires a general builder. The term Residential building work means any work which is involved in building a house or changing or adding to a home. It also comprises of mending, refurbishing, ornamenting or applying shielding treatment to home. A dwelling is defined as a building or a part where people live. This might include an apartment, house or a townhouse.

Here is a list of some of the works that require a building licence:

• construction of a garage, carport or a shed

• renovation for bathroom, kitchen or laundry

• structural landscaping and building swimming pools

• construction of conservatories and atriums

• house lifting for example, raising the height of an existing structure permanently

• removing and resitting dwellings

• steam rooms and saunas.

General building contracts might also involve work that needs a specialist. These works can be appropriately subcontracted. However, this work must be carried out by the container of a permitted contractor licence or competent administrator certificate in that specialist category.

There are a number of different categories of licences that are available depending on whether you want to oversee the work or have an agreement with another party. When you have a contractor licence, you will have the option of submitting a contact to bid on the work. You can only do the categories of work designated on your licence card. Contractor licences can be allotted to people and businesses and partnerships.

With a certificate of a qualified supervisor, you will be able to supervise the type of work specified in the certificate. Such certificates are only issued to individuals and do not allow you to contract for work.

The licence of an endorsed contractor is issued to those individuals who have applied for a contractor licence but also possess the necessary qualifications and experience to become a qualified supervisor.

Can a mortgage include renovation costs?

In a nutshell, a mortgage loan is for the acquisition of an asset, so lenders won’t tend to give you anything else in a mortgage that is going to cover your home renovation costs. When you are applying for your mortgage, your provider will examine the price of your new household. For example, if you’re planning to buy a property for £200,000, but you need another £50,000 to help improve it, you’ll find that your lender might turn you down.

Essentially, with any mortgage loans that you take out on your possessions, the bank or creditor theoretically owns your home till you’ve entirely paid off your loan, which is why it is very unlikely that you will get extra funds from them. There are some mortgage providers who will be willing to add on some building costs, but it is entirely up to you whether to choose it or not.

With most mortgages, banks and other lenders will usually give you a maximum of 95% of what you purchased your property for. That means, that even if you contemplate the household has the probability to be valued at so much more, you’ll have to find an alternative way of paying for the developments you have in attention. So, if the accumulation of extra funds on to your mortgage loan is out of the question, you’ll need to find additional ways of paying for the home developments.

It is well and good if you have the cash saved up, or else, you can explore other payment options which your bank or lender may be able to help you with. There are several methods by which you can collect the cost to pay for the improvements, from personal loans to credit cards or even overdrafts, there are tons of ways to lending money. Keep in mind these are all forms of debt so keep an eye out for the interest rates when you are repaying.

how long does a loft conversion take?

If you’re about to carry out a loft conversion project, you’d probably be wondering how long it’ll take to complete the task. Well, you’re not alone! This is one of the most common questions when it comes to loft conversion projects, however, providing a set timeframe for completion of such projects is impossible as all loft conversions vary. There are different factors that can determine the duration of your project. These factors include, the materials to be used, the type of the proposed loft conversion, the kind of staircase you’ll like to have installed, the number of windows included, the number of rooms to be added as well as a number of other influencing factors. As a result of these variables, the milestones and timings provided are only to be taken as guidelines. If you’d really like to have a set date, you can get in touch with a professional for help.

Generally, it’ll take up to 8 weeks to complete a loft conversion project.

✓ The first week activities will include putting up scaffolding, receiving the first materials for the build and creating an opening in the roof to gain access to the loft space.

✓ In the second week, the structure of the roof will be ammended and more support added.

✓ Third week, the floor joists will be fitted, building of the loft conversion will start, completion of the external roof works and commencement of plumbing and electric works.

✓ Fourth week, complete the building, construct the loft floor, fit the roof windows, insulation, ventilation and internal stud walls.

✓ Fifth week, apply plaster and plasterboard to the room walls, create a staircase opening and fit the new staircase.

✓ Sixth week, plaster the staircase area, complete plumbing and electrical works, hang the doors, fit skirting, handrails and bannisters and start decoration.

✓ Seventh week, complete the decoration and clean and wipe out all wastes.

✓ Eight week, complete all the remaining tasks.

Is external wall insulation safe?

With the numerous benefits that comes with the installation of an external wall insulation in a building, it’s also important to find out whether it’s also safe before proceeding to fit one in your home. Firstly, to ensure that external wall insulation systems are safe, they must be BBA approved, which means they’ve been subjected to a thorough testing by the British Board of Agrement and therefore, suitable for use in UK homes.

Given the fact that cladding materials have recently generated a lot of debate and negative press about how reliable some particular materials are, questions are being asked of the safety and reliability of external wall insulation. However we must clarify that, although external wall insulation can be classified under cladding, it is very different to rainscreen cladding - which caused the Grenfell fire tragedy.

External wall insulation is completely safe. However, when it comes to fire, the safety of your system depends largely on the insulation type in question. The safest type of insulation you can have installed is the Rockwool insulation boards which are rated as Euroclass A1 non-combustible. The board is specially designed in such a way that it contains fire - preventing it from reaching the other areas of the building. They also do not produce harmful emission or smoke when impacted by fire.

Meanwhile, the Wood Fibre, is also a great insulation which is known to char and not burn. Contrary to many beliefs, it actually burns slowly creating this charring effect which produces an oxygen barrier that helps reduce the spread of fire.

To make your system safer, you can also make use of Fibreglass Mesh for reinforcement. It helps to improve the strength of the tensile which promotes the security of the boards attached to the wall.

Does external wall insulation add value to your home?

The answer is yes! Houses whose external walls have been insulated are more valuable than their uninsulated counterparts. And not only does it add to the value of a home, but also significantly reduces the amount of electricity consumption. This is a major turn on for potential investors which implies a greater demand and ultimately, a higher price. The real estate market is a very dynamic one which can be hard to predict at any particular time. The frequent changes in price are usually down to factors beyond the owners’ control, but if you’re looking to put up your house for sale in the near future, it would be a wise decision to consider ways in which you can increase its value. While renovating each room can be on the expensive side, a great solution would be insulate the external walls.

An insulated house is one that is well secured against the harmful impact of extremely high or low temperature, humidity and other atmospheric factors. Hence, the reason why a house with external wall insulation has a greater value which you would not want to miss out on. What’s more? You’ll get a great thermal insulation with the top notch materials like foamed polystyrene, high quality renders, mineral wool or polyurethane.

With an external wall insulation, you know the transaction will always be favourable on both ends. You get to smile to the bank, while the buyer also gets to enjoy great value for every penny spent. To employ the services of a reliable external wall insulation expert, simply conduct an in depth research from family and friends, online and other sources. Go through their online reviews and ask questions to become more familiar with the process and its value-adding potentials.

how to refurbish your house?

If you’re thinking about refurbishing your house or property but don’t know how to go about it, then you’ve come to the right place. In truth, not every home refurbishment works goes in exactly the same order, however it’ll do you some good to abide by a specific plan in order to avoid both unnecessary works as well as expenses. For instance, how would it feel if you have already closed walls and paint only to realize that there’s a need to include a new plumbing stack that has to go behind the wall? Not good, right? Well, this guide is designed to help you avoid such frustrating situations. Let’s have a look!

✓ Establish a plan. This involves carrying out a good assessment of what you’d like to refurbish and set the priorities like deciding where to start and making sure you have both the time and budget to complete the project.

✓ Set a budget. Establish a final amount that’ll be the threshold to your spending. It’s always good to add an additional 10% to 15% to cover unexpected costs.

✓ Hire a contractor. Carry out a research, reach out to many contractors, compare their prices, work quality as well as integrity before hiring.

✓ Talk to your insurance company. Find out if you have the amount of coverage that suits your needs from your insurance company before and after your project.

✓ Secure permits and order materials. Make sure you check with the latest regulations before commencement. Once done, you can start ordering the required materials.

✓ Start demolition. This is optional as it only applies if space is being added.

✓ Work behind the walls. This include doing all the works necessary behind the walls like plumbing, electrical, heating etc.

✓ Paint and install flooring

✓ Fit in the cabinetry

✓ Add finishing touches. This includes the last details and decorations.

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.

How long will a loft conversion take?

It depends on the style and size of the conversion, but in general, a loft conversion will take between 1-2 months. A loft conversion is a substantial building project, and plans will need to be drawn up. This may add to the time it takes to complete your loft conversion.
