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

can a mortgage include renovation costs?

It can be very hurtful when you’re looking to get a house and then identifies one that’s almost perfect, but that one thing that’s lacking is significant enough to prevent you from making an offer. For instance, you may like neighbourhood, the lot’s size, the number of bedroom and lots more. However, the only thing that’s holding you from making an offer is the outdated kitchen. This is the point where you wonder whether a mortgage can include the cost of renovation. In this article, we’re going to give you a good insight into this and more. Let’s have a look!

One of the major things your lender will put into consideration when you apply for a mortgage is the price of the property in question. For instance, so you’ve found your “almost perfect home for let’s say £400,000 and the cost of your intended renovation work runs up to about £150,000. In this event, you’re definitely going to find lenders who wouldn’t be too keen to let go of their cash. And that’s mainly due to the fact that lenders are only able to afford you, at best, 95 percent of the purchasing price. In other words, if you really want the house, you’ll have to finance it yourself no matter how much potential you think the house possesses.

This, however, does not mean that you can’t find some mortgage lenders who’ll allow for building costs. They exist, but this will mostly take place when the work is complete and the property is revalued. You may also be lucky enough to get a purchase plus improvements mortgage which allows you to renovate now and pay off the renovations over time at a better interest rate than other loan types.

do i need building regs for a garage conversion?

Are you considering converting your garage into a more usable space in your home? If yes, then you’d probably want to know if you’ll require building regs before converting the garage. The answer to this question is yes. Although you may not require planning approval to convert your garage into a more usable space, but you’d usually need approval under the Building Regulations.

When re-structuring your garage into a habitable space, the following should be taken into consideration: structural alterations, ventilation, moisture proofing, insulation, fireproofing, escape routes as well as the submission of a building building notice or full plan application to the local council in order to inform them about the planned project.

• Walls

You’ll require an approval if you plan to infill the garage door with a window and a new wall. This is because the garage may have been built of a shallow slab which implies that a new foundation would be needed for the new wall construction.

• Floor

Even though there’s a high possibility that the garage floor is strong enough for domestic use since its designed to withstand the weight of vehicles, you may however need to upgrade to make sure it suitable for both thermal insulation and damp proofing. In addition, there may also be the need to to alter the floor level in such a way that it matches that of the remaining parts of the house.

• Ventilation

According to the Building Regulations requirements, there’s a need for adequate ventilation for each individual rooms which includes garage conversions for general health purposes. What’s going to determine the ventilation level that’ll be required is the frequency at which the room is used. Ventilation can be provided through purge or simply opening the window or via trickle ventilation.

how much value does a loft conversion add?

When its impossible to build out and create more space sideways, why can’t you look upwards? As more and more homeowners in the UK are carrying out their loft conversion project, one question that keeps popping up is the amount of value the loft conversion can add to their homes. However, this is a question that is impossible to provide a single and precise answer to. This is because the value that’ll be generated by a loft conversion is largely dependent on a wide range of influencing factors. To give you a vague idea of the loft conversion value to a property, we’ve put forward a research carried out by industry experts so you can know what you’re in for.

Nationwide carried out a research which shows clearly that a loft conversion including an additional bedroom as part of the building plan will increase a house’s value by up to 21 percent. Since the number of rooms a house has is one of the main metrics for house valuations, loft conversion comes in pretty handy as it’s a great and easy way to convert your house from a 4 bedroom house to a 5 bedroom house prior to sale.

Apart from the financial value aspect, loft conversion also adds more value to your lifestyle which is very unlike nearly other financial investments you can make. More space in your house automatically means more storage or a new room as you wish. A new room can be for a growing family or probably to serve as a guest room. It can also be used as a study space or even an office especially with the rapidly growing rate of people working from home. With loft conversion, the possibilities in terms of value are simply endless!

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.

Are barn conversions VAT exempt?

If you’ve converted a non-residential barn into a home, you might be able to reclaim some of the VAT that you’ve paid for your project. This includes money spent on:

• Construction materials

• Flooring

• Light fittings

• Kitchen units and worktops

• Electrical, heating and plumbing materials

To reclaim your VAT from HMRC, make sure you request and keep all of your invoices. You’ll also need proof of planning permission and evidence of completion. You should then submit your claim with all relevant paperwork within three months of receiving your completion certificate. You’re only allowed to submit one claim, so you’ll need to make sure you get it right first time.

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 does cavity wall insulation work?

In recent times, more and more home and property owners are starting to come to terms with the large returns and little investment in cavity wall insulation provides. For a relatively little amount you can achieve a lot, from an increase in your home’s energy efficiency and reduction in heating bills to a huge boost in your property’s resale value and lots more. This makes you wonder how an ordinary insulation can help you achieve so much, right? Well, you’re definitely not alone! Several other potential investors are also eager to know exactly how the cavity wall insulation works to deliver all these juicy benefits. In this post, we’re going to go provide you with a detailed insight on how cavity wall insulation works. Let’s take a look!

 

Typically, cavity wall insulation works as acting as a shield which prevents the escape of heat from your home. It features a reflective surface which serves as a barrier to reflect heat from one side of the panel, effectively minimizing the amount of heat conduction that escapes through. This protection of your home from heat penetration comes with a couple of benefits with the obvious one being an incredible thermal efficiency. An insulated home or property is able to maintain a much more balanced temperature throughout the year – staying a lot cooler during the summer months and retain the heat generated during the winter months. However, a less talked about benefit is the fact that when an insulation is done during the construction of a house, the whole development phase can be completed a lot quicker. This is mainly because insulation offers total protection against weather conditions which enables internal trades to continue without the need to wait for brickwork or cladding to be completed.
