How much do Builder services cost?

How much do Builders cost? Prices for Builders in 2026 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.

is a porch made from uPVC?

The simple answer to this question is... they can be! Although there are many types of porch designs that are available in the market, the uPVC porch happens to be one of the most loved and cost effective. Most home and property owners prefer the installation of a uPVC porch for a number of reasons. These includes:

• Value for money

It’s no coincidence the uPVC is widely accepted across the building industry with a plethora of uses. Not only is it relatively inexpensive to manufacture, but even the recycled uPVC is now becoming more and more useful. UPVC’s main rivals are wood and aluminium, and both are way more expensive to incorporate for frame profiles. Therefore, making use of uPVC is going to make your initial costs relatively low.

• Life Span

Although the main rivals in both hardwood and aluminium can also boast a lengthy lifespan just as uPVC. However, considering the price that you can get a uPVC, the lifespan is just incredible as it can be measured in decades.

• Aesthetic Appeal

UPVC gives you a wide range of foil colours that’ll fit your home perfectly well while also enhancing it’s visual appeal. You can actually get a porch that looks exactly like it’s manufactured from timber frames. To achieve this, all you need to do would be to make use of a wood grain surface finish. This is also long lasting, strong and resistant to fade.

• Little Maintenance

This is a very common feature of uPVC that makes it even more advantageous when used in making a porch. Unlike timber or wood which swells due to absorption of water or shrinks, you’ll never need to worry about all these distortions and more with uPVC. No painting, no sanding and ultimately, low maintenance required.

does loft insulation cause condensation?

The short and simple answer to this question is yes, loft insulation does cause condensation. Over the years, problems with condensation in loft spaces have become increasingly common. While this may not be harmful in anyway, when the condensation becomes excessive it can lead to more serious issues taking root in your loft like wet rot, dry rot as well as black spot mould. Generally, the best thing to do if you’re concerned about the condensation in your loft space and that it may rapidly become a bigger problem is to get in touch with a damp specialist as soon as possible.

 

Even though insulating your loft space comes with a wide array of benefits like making the top floor rooms warmer, it’s however comes at the cost of making your loft or room space cooler. Condensation in lofts take place primarily due to the humid air making its way through insulation or other gaps into the loft space and touching a cooler surface which in turn results in beads of moisture on the timbers, lintels as well as the underside of the roof. This is why its always a great idea make use of thermal insulation with a vapour barrier that’s installed on the warmer side of the insulating material.

 

Condensation in loft is caused by excess moisture in the air and lack of adequate air ventilation. Here are some top reasons that gives rise to this in the loft:

  • Extra insulation has been installed in the loft leading to a restriction on the natural air circulation in the property.
  • When the storage boxes or other items that has been stockpiled in the loft blocks the roof vents.
  • The release of steam and moist air into the loft space by hot water tanks.
How much sand do I need for bricklaying?

Sand is a very important element in bricklaying as far as a mortar mix is concerned. Generally, the quality of the sand is the major factor determining the quality of a plaster mix or mortar mix. It’s recommended that the sand should have enough ‘fines’ (- 75 micron material) to get a good plastic mix with a water content that’s less than 350 litres/m3. Generally, a mortar mix or plaster mix is made within the range of one bag of cement to 200 to 300 litres of damp sand.

Apart from experience the next best indicator of the quality of sand is a field test. In other words, if you do not have the required training or experience in bricklaying, the best bet to determine the amount of sand for a good quality mix is by carrying out a field test. Let’s have a look!

• Get about 50kg of sand and air dry it.

• Scoop 25kg of the sand, 5 kg of cement as well as litres of water ( with 1 litre and 1.5 litres of the water in different containers).

• Mix the cement and sand to form a smooth, uniform and consistent colour.

• One after the other, mix the the sand - cement mixture in the three quantities of water. Do this until you’re able to achieve a mix that’s workable enough to use as plaster.

With that done, you should take note that if 5 litres of water is sufficient then the quality and quantity of the sand is perfect. If you’d require 6 litres of water to get a mix workable as a plaster, then both the quality and quantity of the sand is average. However, if you’d need 7 litres of water to get a mix workable as a plaster, then the quality of the sand is poor. Any requirement of water above 7 litres implies a very poor quality of sand.

Can an extension add value to my home?

Yes. Most extensions will add substantial value to your home, and you may find that the extension adds more value than it cost. However, it’s important to be sure that the home remains balanced. Extending your garage and leaving your property with no parking spaces, for example, may impact your ability to sell.

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.

How to find a builder for a house extension?

Builders are everywhere, but finding one for your project can be tricky and stressful, with both cost and reliability coming into question. This is even more worrisome when you’re fully aware that your house extension can only be as good as the builder. If you’re also facing the same challenge, then you’ve come to the right place. In this article, we’ll share with you some tips on how to choose a professional and reliable builder who’ll ensure you get immense value for every penny spent. Let’s take a look!

✓ Ask for recommendations. To find a tradesperson, not just a builder, personal recommendations is the best way to go. Building a house extension is a major undertaking which comes with a lot of costs, so if you’re going to do it the least you can do is ensure you do it right. Carry out your research, ask friends and family, neighbours and loved ones if the know of any reliable builder in the local area. If they’ve have one they’ve used, you can request for the cost, quality of the job done, the duration of the project and any other detail you feel you should know.

✓ Search Online. Use our search feature to look at the builders available or submit and enquiry and we will find you one. Our site holds details of numerous builders and building companies which you can go through their ratings to select the best.

✓ Select a reliable builder from trading association. Most reliable builders are usually a member of a recognized trading association or the other. Though this is not obligatory for builders, but it can be used as a dependable medium to find a good builder. We list what trade association the builders are a member of.

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.
