How does it calculate?
The rear extension cost calculator UK initiates the calculation by multiplying the estimated per SQM cost with the extension size. The estimated per SQM cost is the standard estimation as per the construction cost in the United Kingdom.
Additionally, the calculator’s estimate is influenced by the region where your property is located. Construction costs can vary across different parts of the UK, with London and the South East generally being more expensive than other areas due to higher labor and material costs. However, the calculator is designed to account for these regional variations, so you can get a more accurate estimate for your specific location.
It is important to note that this cost calculator provides an initial estimate and should not be considered a final price. Various other factors can influence the actual cost of your rear extension. These can include the complexity of the design, the need for specialist contractors, unforeseen issues such as structural work, and potential planning permission requirements.
For instance, if your extension requires significant alterations to your current structure or involves substantial groundwork, such as foundation reinforcement or drainage work, this can add to the overall cost. In some cases, a rear extension may require detailed planning permission or building regulations approval, which can add both time and costs to the project.
Moreover, if you are adding additional features like large windows, bi-fold doors, or skylights, these elements may contribute to higher costs due to the complexity of installation and the quality of the materials chosen. The calculator can help you identify rough costs, but consulting with a builder or contractor for a more accurate quote is recommended before proceeding with the work.
Our rear extension cost calculator UK offers a straightforward way to estimate your project’s costs and plan your budget accordingly. It is an excellent starting point to get an overview of the potential expenses, but always keep in mind that further consultation and detailed planning are essential for a successful and cost-effective rear extension.
