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

how much loft insulation do I need?

Over the years, more and more home and property owners are beginning to realize the huge benefits that can be derived from loft insulation being a worthwhile investment. It’s quite worrisome the way in which energy bills have soared over the past 10 years and loft insulation is a considerable affordable energy efficiency measure that can go a long way to help increase your home’s energy savings.

 

As far back as the 1980’s, the standard when it comes to insulation thickness was 25 mm to 50 mm which was, at the time, considered to be sufficient. However, building regulations have changed the norm that now states that a new build needs to possess 270 mm of insulation in the loft in order to achieve the required u-value of less than 0.16/m2k based on the standard rock wool or sheep wool insulation.

 

Generally with loft insulation, there’s a law of depreciating returns which implies that the first couple of insulation centimetres will save you many times the cost of the installation, however an extra layer or centimetre is going to add less value to the point where it’ll no longer be wise or worthwhile to add any further centimetre. Therefore, with cheaper energy prices 30 years back, that additional couple of centimetres was not just worthwhile, but with the recent alarming rises in costs of fuel, that additional £10 savings per year has all of sudden changed to £30 which makes it become a lot more attractive.

 

If you already have 270 mm of loft insulation, regardless of the material you’re looking to add you’re most likely not going to benefit from a top up. The cost of the materials and installation will definitely be too high for the couple of pounds it’ll save you per year.

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.

Will insulation save me money on my energy bills?

This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.

how thick should loft insulation be?

Over the years there has been an increase in the recommended thickness of loft insulation by the government. Obviously, the reason behind this is pretty simply - the thicker the layer of your loft insulation the bigger your savings. The UK government is very keen to every house in the country to have loft insulation fitted where possible as it helps to minimize the heating demands of these properties. Households get to benefit from loft insulation in so many ways which includes reduced energy energy bills as well as having a home that stays at a more comfortable temperature for longer.

 

Generally, for the government energy efficiency is crucial as it implies that the highest demand ( which is usually the time of the day when gas or electricity use is at its peak ) reduces, since each building requires slightly less energy. Overall, that ultimately implies that new power plants don’t have to be built which is some nice cost savings for the government.

 

In the 1980’s, any thickness of loft insulation from 25 mm to 50 mm was considered the standard. But then, building regulations stated that homes should have as much as 100 mm of loft insulation. Over time, this gradually increased to 270mm for new builds and also recommended for other properties, although not essential. As a result of this, there’s always a need to check how much insulation you currently have in your loft before you decide to purchase more. You may discover that you already have something within the range of 20 mm to 200 mm up there and knowing this and the insulation values will assist in determining how much more you’ll need to purchase, if any at all. You should also note that some modern materials can offer the same thermal insulation whilst not being as thick.

How many bricks can a bricklayer lay in a day?

Well, just like many other team work, a bricklayer is only as good as his supporting cast. And a hard-working labourer should be able to keep three bricklayer gangs happy. But even when he gets to serve just one bricklayer, the site conditions and nature of the wall can also play a huge role in determining the number of bricks that can be laid within 24 hours.

With the best possible site condition, hard-working labourer and best scenario with no pillars, no face brick, long straight wall and no wall ties, a well trained bricklayer should be able to lay within a range of 800 to 1100 bricks all day long. However, you rarely get walls like this as there is always going to be some corner or curve somewhere which usually takes some time to get right. Furthermore, once the bricklayer has laid up to 5 feet, there’ll be a need to get some lift. From that point onwards, the job understandably gets slower and tougher - meaning there’ll most definitely be a face brick.

In addition, there are multiple other factors that can affect the number of bricks that can be laid in a day. Sometimes its the complex designs or weather that’ll determine the daily rate.

With the aforementioned factors and more realistically, on a good day and great site, an expert bricklayer should be able to lay about 500 to 800 bricks in a day. This is generally a very good target, but of course you never can tell with the reasons above and other factors that are simply beyond the control of the bricklayer. If you have a project and want it completed as soon as possible, you can pay the bricklayers based on the number of bricks laid to increase their efficiency.

Are barn conversions a good investment?

A barn conversion can be a great investment for lots of reasons. When done well, barn conversions can be great at holding their value, meaning you could sell yours for a great price. They can also look fantastic, often with period features coupled with large areas of glazing. This can make them a great place to live, especially if you enjoy being in the countryside.

However, barn conversions do have their disadvantages. They may require extensive renovation work to bring their energy efficiency levels up to standard, which can be very expensive. It’s also important to be aware of their location – they might be on a working farm or close to several other converted buildings.

It’s essential to get a survey conducted before you buy a barn you plan to convert. This can tell you about any structural problems it might have and give you an indication of whether you might be able to get permission to convert it. You can also buy barns with planning permission already in place.

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.

do i need planning permission to render my house?

If you’re considering rendering your house or property, then you’d most likely want to know whether or not applying for a planning permission will be needed. In several cases, planning permission will not be required for the maintenance, repair as well as replacement of the existing render on your building. These activities are covered by what’s called “Permitted Development Rights, which allows you to carry out some activities without having to apply for a planning permission but always subject to following some strict guidelines. For rendering, as long as the material (render) possesses an identical appearance to those existing on the house as well as same colour, then you will not require a planning permission. However, there are a number of projects that have been highlighted in which a planning permission would be required. These includes the following:

✓ Re-rendering in a colour that different from the original one used on the house or building.

✓ Rendering over brickwork which was not originally covered.

✓ Rendering over pebbledash

✓ Removing pebbledash and replacing it with render.

Another exception to the Permitted Development rights are for houses in conservation areas, national parks or areas of outstanding national beauty.

Although, you wouldn’t normally require to submit a planning application for approval before you apply render, but in truth it’s actually a bit of a grey area which isn’t totally clear and doesn’t allow for much freedom or creativity. And due to this fact, homeowners who wants an absolute peace of mind may opt to apply for planning permission just in case. It’s also worth noting that whether or not a planning permission is required, a huge rendering work will need to comply with building regulations which includes the need to insulate walls on the inside or outside as part of the work on several older properties .
