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

do you need planning permission for a porch?

There are so many benefits that comes with building a porch in your home premises. It’s an extra space where a lot can be achieved such as drying a dripping wet dog, taking off your dirty shoes or boot and lots more. So if you’re considering to construct a porch, it’s definitely going to be a wise decision. However, before you get started, there’s a need to determine if you’ll need planning permission for a porch. It’s important to take note that planning laws are dynamic and can be updated at any point, so be sure only to use trusted sources only as your guide. If you’re the homeowner or landlord, it’s entirely your responsibility to obtain the right approval for any development project you wish to carry out within your premises.

A Porch can not be termed as an extension and neither is it a conservatory, they’re basically built to the home’s front covering the main entrance using a stone base or a brick. As a result, a porch does not need planning permission due to the fact that it’s covered by the permitted development rights if the specific guidelines for porches are complied with. Below are the instances where you WILL need planning permission for a porch.

✓ If the floor space is more than 3sqm (the wall inclusive).

✓ The highest point has a height of more than 3 metres.

✓ If the porch is situated within 2 metres of a boundary directly facing on to the road.

You may need planning permission if the house is a listed building, designated area or falls under an Article 4 Direction.

In order to build a porch without planning permission, you need to consider all the criteria stated above. You can also visit the Planning Portal website to get more detailed information before getting started.

do i need planning permission for a garage conversion?

Are you thinking about converting your garage into a new space? Be it a new bedroom, gym, library or playroom, one thing you’ll have to consider before getting started is whether or not you’re going to require a planning permission. Unlike extensions that needs additional space, garage conversion is all about changing the existing structure of a space that’s already available to you - your garage. As a result, these projects are mostly covered by a planning policy that’s a bit different.

For a garage conversion, it’s very unlikely that you’ll need a planning permission. As a matter of fact, only 10 percent of garage conversions has been estimated to need a full planning permission, with the others coming under the permitted development rights. The permitted development rights, however, only provides coverage for home improvements that’s internal which implies that so far you’re not trying to enlarge your garage, you’ll not require a planning permission. But if otherwise, you’ll have to submit an application before commencing your project.

If you’re looking to comply with the permitted development rights, then your project must comply with some specific guidelines. These rules include the following:

• The work should be internal. No plans to enlarge or extend the existing garage.

• You should make sure that the materials used in carrying out the garage conversion is the same with the materials used in building the existing house.

• The building should not be extended.

You may, however, require a planning permission if you’re going to change a detached garage into a living space which could be a bedroom, small annexe or a living room.

Some houses excluded from the permitted development rights include flats, listed buildings, some new developments and most homes in a conservation area.

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.

• Dormer Loft Conversion

does a single storey extension add value to your house?

Does A Single Storey Extension Add Value To Your House?

When you’re looking to construct a single storey extension or perhaps you’re just searching for means to increase the value of your property, this question always pops up. The short and simple answer to this question is a resounding yes, a single storey extension can go a long way to increase the value of your property. Just like any other home improvement, when done right, adding a little extra living space is one of the top things you can probably think of that’ll provide a cool increase in your property’s value. However, before you rush in you must also take note of some factors so you can be certain a single storey extension is the right option for you. These factors include the quality of the build, complexity of the build, cost of the build versus the value gain, ceiling price in the area, finance costs as well as the inconveniences and stress.

Generally, the average cost of a single storey extension can range from £34,000 to £37,000. For this price, you should get a standard sized rear or side extension which also includes the cost of a kitchen - it’s the most commonly use for a single story extension especially in the UK. So it’s important to know the value they’ll add to your house before deciding to make such an investment.

The value added to your property will depend largely on the quality and size of your single storey extension. The value is usually calculated by estate agents using the number of bedrooms, bathrooms as well as the floor area. Inside London, it’ll typically be priced at £5,000 to £10,000 per square metre, while outside London should be within the range of £900 to £2,000 per square metre.

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 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.

What time can builders start work?

The periods at which noisy work is permitted do vary across the nation because the Control of Pollution Act 1974 provided Local Authorities with the authority to regulate noise from construction sites and similar areas. At the same time as these do differ across unalike councils, the average hours throughout which noisy work is tolerable is usually between 8 am and 6 pm from Monday to Friday. This is usually based on the impression of ‘noisy work’ being carried out, so labours could start earlier to prepare things for the day but then not start carrying out their work until 8 am.

On Saturday’s builders are usually allowed to work between 8 am and 1 pm, but this can differ to some extent with different councils. It does mean that workers can start at the identical time as the rest of the week, but they are generally required to finish a lot prior. On Sundays and Bank Holidays there is not as much of detailed direction on hours, but most councils say that there should be no noisy work taking place. Although these are decent strategies, it is worth examining your Local Authority website as they can change slightly. Noisy work is commonly described as ‘noise audible at the site boundary’ and it may be the case that workers are there outside these hours but are setting up before carrying out noisy work.

Local Authorities also recognise that now and then it is unescapable to work separately to these hours, such as work on railway tracks that must be done when trains are not running. Though, local councils do have the authority to serve an announcement on individuals carrying out building or demolition works and tell them how the work should be carried out to evade a possible lawful noise irritation.

How much is plasterboard?

How Much Is Plasterboard?

Do you wish to install plasterboard in the nearest future? If yes, then you’d probably want to know the amount it’s going to cost. Here, we’ll give you a detailed plasterboarding prices breakdown to help you calculate an estimate for your project.

A plasterboarding project including the cost of both materials and labour with the use of a high quality panels is about £4 to £5 per panel. Therefore, if you wish to calculate on the basis of a standard room about 12x12ft would cost about £500 to £600. However, this price can fluctuate significantly depending on the professional as well as the quality of the materials you wish to incorporate in completing the project. We’d recommend that you hire the services of a professional with accreditation as he would provide you with a detailed quote with no hidden charges or costs. To give you a clearer idea, we’ve taken the time out to put together some estimated costs of employing the services of a seasoned professional plasterer to supply and plasterboard your home or office. Let’s take a look!

• A 6 x 12ft room with panels and plasterboard should have an average cost within the range of £250 to £400 and duration of one to two days.

• The individual cost of plasterboarding or drywalling a standard 12 x 12ft room should have an average cost within the range of £500 to £600 and duration of one to three days. These includes 60% for materials used (£330), 30% for tradespersons (£165) and the remaining 10% for waste removal (£55) to give a total cost of £550.

• A 12 x 24ft room with panels and plasterboard should have an average cost within the range of £1000 to £1200 and duration of three to six days.
