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 does a garden room cost?

Adding a garden room to your property is a great way of creating an additional space within your home without having to invest heavily in large house extension projects. And not only does it expand your living space, but it’s also a way to add good value to your home or property. With the various benefits offered by a garden room, most individuals are usually surprised with just how affordable the living space can be. However, just like any other home improvement, the price of a garden room is influenced by a wide range of factors. These factors include the design you opt for whether standard or customized, the size of the garden room, the materials used, the number of fixtures and fittings you want as well as any other special design feature you require.

Asides from the money needed to put up the structure, there are also some common extra cost that’ll also be expended for both the interior and exterior of the living space. For instance, there are some furnitures and fittings that you’d like to put in your garden room and these will also form part of the overall cost. There’s also the electrical connections cost and this will vary depending on the distance of your room, the cables to be used as well as your electrician. For this part, you can expect to spend anything within the range of £850 to £1200 and since it’ll be used all year long, it’ll also require appliances for heating, insulation, electricity and ventilation.

Generally, the overall cost you should be expecting to pay for a modular build garden room will range between £10,000 to £40,000.

what is a porch?

A porch is a small and low structure (with a roof) located at the main entrance of a building or house.

In addition, some homes may have a three-season porch or sun porch. This may be situated by the side of the house and covered by the roof overhang - they’re usually screened in to offer good access all year round.

Generally, porches serve a wide range of purposes. They include:

• Provision of an outdoor living space to relax during the summer months

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.

✓ Get the necessary tools. You’re going to need a broom ( to clean the area), caulking gun ( to fill the hole), a hand tamp a plate compactor or a hammer ( to level the filled in hole) and a weeding glove (just in case there are weeds growing in the hole).

✓ Prepare the area. Do this by weeding the plants or weeds that might have grown inside the hole and identify your asphalt filler.

✓ Wet your soil, if necessary. It’s important to note that this is only necessary if your soil is dry to help the filler stick properly.

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.

how to lay loft boards?

How To Lay Loft Boards

Do you need more storage space in your home or property? If you live in a tiny space especially where extensions can’t be made sideways, why not look to the topmost area of your home and consider boarding out your loft to make it usable?

Boarding your loft can make for a fairly easy DIY project but like every other home improvement tasks, it requires some specific skill sets as well as knowledge for a successful construction. Therefore, we’d recommend you hire the services of a reliable professional in order to guarantee the best possible outcome, especially if you lack proper training or experience that’ll help you avoid some costly mistakes. Here, we’ll give you a good insight into the loft board laying procedures.

• Get The Right Tools & Equipment

The materials and supplies you’ll need to lay loft boards include loft boards, screws, tape measure and pencil, drill, hammer, saw, protective gear such as gloves and dust mask.

• Work Out The Area

Measure up the area you need the boards to cover. The standard loft features two different sizes (both are 18mm thick) which include 2400mm x 600mm and 1220mm x 320mm. You should ensure that the board you opt for fits through the loft hatch perfectly.

• Start Laying

Once you’re done working out the area, the next step is to put on your protective gear and start putting the boards in place. You should lay the boards in a staggered pattern so as to give a better strength. While doing this, watch out for any wire running through your loft so they don’t get trapped, you should also cut the boards for easy access to the light fittings’ top.

• Make It Permanent

Upon the successful placement of the boards in a way that offer a safe area to store things and stand on, you’ll have to screw them in place. Start by drilling 2 or 5 holes along the edge of individual boards in such a way that lines up with the centre of the joist below. Once done, then you can fix them in place with screws.
