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

Are there grants available for external wall insulation?

External wall insulation works to keep your home cosy and comfy while also helping to cut the energy bills. However with the great benefits also comes great costs, so it’s actually a logical decision to know whether there are grants out there which you’re eligible for to help you handle the cost of the external wall insulation.

There are grants available for external wall insulation, but rarely will you find one that covers the full installation cost. With the help of the government’s Energy Company Obligation (ECO) scheme, a couple of energy companies assist in making your home more energy efficient by offering grants or free insulation. In certain cases whereby you receive particular state benefits, you may as well qualify for a higher grant that’ll cover more of the insulation cost.

However, if your energy supplier doesn’t offer any grant, you need not worry as you can save as much on energy bill after installation. Here’s what insulation can help you save per year on energy bills:

• Floor insulation can help you save within a range of £30 to £75 each year.

• Cavity wall insulation can help you save about £85 to £280 a year.

• Loft Insulation (270mm) can help you save about £135 to £250 a year.

Generally, the amount you’ll be able to save on your energy bills depends mainly on the type and size of your property, as well as how energy efficient it already is without the insulation. In the long run, your external wall insulation will more than give you back your investment on the valuable project through your savings on energy bills. In other words, whether or not you’re eligible for a grant should never stop you from installing an external wall insulation.

what are fitted wardrobes made from?

Storage space is a major consideration for most home buyers and even more so, when there’s the presence of fitted wardrobes. Fitted wardrobes can be installed in just about any room in the house and even in rather obscure places such as under the stairs, inside a loft, around chimneys as well as into alcoves. As a result, they’re important assets to have as they can go a long way to increase the value of your home or property.

Fitted wardrobes are usually made from various types of woods as well as wood finishes. Typically, they’re installed with either sliding or hinged doors depending on the space as well as the styling you opt for. Fitted wardrobes can be personalized through the addition of elegant features such as custom lighting, mirrors as well as internal extras like pull out shoe racks and pull down hanging rails.

can i refurbish a house in conservation area?

Due to the fact that we live in a country (the UK) with so much history as well as architectural beauty, there’s a need to have what’s commonly called “Conservation Area. A Conservation Area is basically an area which is designated by the local authority and is established in order to protect and enhance areas of historical and architectural interest which includes both rural and urban areas. Therefore, when it comes to refurbishment project in a conservation area, there’s usually a lot of things that needs to be put into consideration as well as hurdles to scale in order to make alterations to your property without any interruptions from the law.

In general, all properties in a conservation area have strict regulations governing the outlook of the houses, as this plays a major role in the appearance of the area as a whole. As a result, if you wish to bring down a building, fence, wall or even railing and the likes, you’ll need to obtain prior consent before you proceed. An easy way to go about any refurbishment plan is to to ensure the usage of exactly the same materials that exists in the current house. When you abide by the rules, you’ll be in a more favourable position to acquire the needed prior consent.

The short and simple answer to the question is yes, you can refurbish a house in a conservation area but subject to the approval of the local authority through a planning permission. And when it comes to submitting a planning application for approval, some are aspects will usually be subjected to more intense examinations than the others. Hence, the need to make sure that your refurbishment plans are all friendly in a similar way to the neighbouring buildings and environment.

How long will my garage conversion take?

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.

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.
