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 value does an extension add to your house?

Are you interested in extending your home to create more living space? If yes, then you’d probably want to know how much value it can add to your property in order to compare the building costs to the potential value gain. Well, as long as you know what you’re doing, your house doesn’t necessarily have to be a money pit. So what are your options when talking about home extensions and what’s the associated value to be gained?

• Bathroom Extensions

Although you should have it in mind that bathroom extensions isn’t usually that cheap, but once done, it can increase the value of a standard UK house within the range of £12,000 to £15,000. Meanwhile the finishing cost of a bathroom can range from £2,500 to £7,000.

• Single or Double Storey Extensions

Single storey extensions are always huge when it comes to increasing the value of your home - giving about 4 to 7 percent increase. If it goes that far, then literally nothing beats a full spectrum, double storey extension which can give up to 11 percent increase in the value of a property - equalling about a whooping £33,000 for a standard home in the UK.

• Conservatory Extension

With conservatories becoming more and more popular in the UK due to the weather conditions, several buyers are now including it’s availability as part of the criteria for purchasing a house. Wonder why? This is simply because everyone wants to enjoy their garden all throughout the year. As a result of this high demand, adding this type of extension to your house can go a long way to increase it’s value. However, it’s very important to incorporate high quality materials during construction. With glass conservatories offering, on the average, up to £5,000 increase in value, the cheaper PVC alternative offers much less value and can also deter potential buyers.

how to render a wall?

Wall rendering is basically a process which involves the application of sand, cement or polymer covering to a home’s exterior in such a way that enhances its look while also offering an improved stability. The process is a perfect solution for several exterior concerns mainly due to the support its able to provide. It’s highly beneficial for older homes whose walls may suffer from poor quality because of wear over time, while it’s also greatly advantageous for newer homes as it increases their stability while also enhancing their visual appeal.

Knowing how to apply render is a great skill to have with your home’s upkeep in mind. The project can be done quite easily by any competent and confident DIYer. However if you lack any of those attributes, then we’d recommend you get in touch with a reliable professional for help. In this article, we’ll take you through the wall rendering process.

✓ Prepare the walls. This involves examining the wall, repairing any structural defects as well as stabilizing any movements to prevent the render finish from failing.

✓ External details. This includes the removal of bargeboards, rainwater, soil pipes, alarm boxes and all other external details.

✓ Insulation. In the event whereby external wall insulation is to be fitted, this is the stage to do so.

✓ Developing a foundation for the render to fix to. Apply a render mesh over the insulation, bedded into the first base coat layer of render.

✓ Building up the render.

✓ Render finishes. There are a wide range of colour options as well as various finishes available from very smooth to textured. However, you should note that thin coat render systems are usually designed to be self coloured.

✓ Final finishes. This involves the re-application of the external rainwater, soil pipes and the other external details.

What is a bricklayer?

This is an individual who is trained in the art of working with concrete blocks or bricks, clay bricks as well as other kinds of mortar building materials. In a combination of these materials and good bricklaying skills, a bricklayer can build and repair veneer as well as full brick construction, arches, partitions and other structures.

Contrary to many beliefs, a bricklayer actually does more than laying of bricks. There’s more to being a bricklayer than you can probably think of. A single bricklaying projects requires a wide array of skills. Let’s have a look at these skills!

• Using damp resistant materials to seal foundations.

• Spreading mortar between joints and applying them to serve as a thick layer binding the bricks together in rows.

• Reading and working from specifications as well as plans.

• Working with brick-cutting machines.

• Taking charge and caring for cement blocks or bricks, clay bricks and the likes.

• Construction of scaffolding - subject to possession of some licenses in some states.

A bricklayer mostly works outdoors, in the field and may also work at heights. Depending on the job, a bricklayer can work as part of a team or be in contact with the public. They are mostly recruited by building and construction companies and bricklaying sub contractors. However, they can also set up their own private construction firm or become a self employed tradesperson.

A bricklaying qualification is one of just two construction trades which can continue to become a registered builder. And regardless of the form a bricklaying employment takes, there are certain qualities that makes a really good bricklayer. These includes:

• Ability to work at heights and outdoors

• Enjoy practical work

• Technical aptitude

• Good hand-eye coordination

• Independent and yet a team player too

• Top physical fitness

• Attitude and attendance.

how much value does a garage conversion add?

It’s a fact that a garage conversion can go a long way to add a resale value to a home or property. Therefore, in the event whereby your home already has parking facilities in place you can put into consideration converting your garage into a habitable space which will add to the sales price of the house by adding an extra room or increasing the floor space. So exactly how much does a garage conversion add to your home’s resale value?

Garage conversions can be seen as a cost effective means of adding more space to your house. However, not only does it add space, but can also add up to 20 percent to the value of your home. It’s also a way of adding an extra living space to your home that’s not under strict planning complication unlike the alternatives. Generally, if your garage happens to be connected to your house, the cost of converting it to another room should between £10,000 to £20,000. As a home owner, converting your garage into an extra room can help increase the value of your home by up to £45,000. And if you’re to comply with the set rules under permitted development rights, you may not even require to submit a planning application.

In the event whereby your garage is detached from your house or perhaps you live in a flat ( or maisonette) or a listed building , you’ll need to apply to the local authority before commencing your project. It’s always wise to check if there aren’t any planning conditions attached to your home or property.

what is a garden room extension?

A garden room extension, also referred to as Sunroom or Solarium, is basically a stand alone garden building that’s totally detached from the home. They are typically semi-glazed building that features a tiled roof rather than glass. What would have been good examples of garden rooms extensions include conservatories, orangeries as well as pool houses, however they are constructed with the help of different materials and features which ultimately makes them different to garden rooms.

Garden room extensions are built with the major purpose of adding extra functional living spaces for a wide range of room options such as a second living room, dining room, study space, home garden office or a rehearsal space - the options are numerous. In other words if you’re looking for an additional usable space within your home or property, a garden room extension can be designed to suit your needs. So whether you need comfy sofas for evening relaxations, a sturdy office desk for work or large dining room table for dinners with family and friends, a garden room extension can be all that you need to achieve to your living space goals or just to add more value to your property.

Garden rooms extension has multiple alternatives such as a conservatory, garage conversion, loft conversion, extension and garden rooms. However, it has some great benefits over its alternatives. These benefits include, being very cost effective, hassle free, can be built within 5 to 9 days, rarely requires planning permission, does not require building regulations approval, includes a full professional installation and management without any need for subcontractors, modern and unique as well as being very versatile. Overall, if you’re looking to create an additional space in your home without having to break the bank, then garden room extensions may be your best bet.

Will I need planning permission or building regulations approval?

You may need planning permission if you are planning a larger extension. All extensions will need building regulations approval. An architect can assist with this and if planning permission is required. A reputable contractor will also be able to advise you if this is needed as well.

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 loft insulation flammable?

When thinking about the right insulation material for your loft, some of the first few things that comes to mind is the various properties of that material as well as how good they fit with your home’s needs.naturally, you’d like to ensure that the insulation will be efficient enough to add to the overall energy efficiency of your home, however there are also other features that may not get as much attention but also happens to be equally important. As the primary function of an insulation is to blanket your house to offer a barrier against heat loss, going for an insulation material that’s also fireproof is crucial as loft insulation can burn. Although most insulation materials are fireproof, a myriad of problems can actually make your insulation burn.

 

For instance, fibreglass insulation is produced using glass combined with plastic polymers and is naturally resistant to fire. However, even at that you’d have to be careful with batts that are supported with foil or paper due to the fact that these materials can burn pretty quickly. Cellulose, on the other hand, is not fireproof and is required to be treated by other flame retardants in order to help reduce combustion. Some of the best insulation materials that are resistant to fire includes the following:

  • Fibre glass. This is made of glass that’s spun into fibres, then combined using plastic polymers. As a result, fiberglass insulation is naturally resistant to fire.
  • Mineral wool. Having a high melting temperature, this insulation material happens to be a great fit for thermal applications due to its superior fire resistant properties. In fact, mineral wool is still naturally non-combustible even if composed of recycled iron and steel by-products, or from actual mineral rock itself.
