The Importance of Budgeting for Your Home Extension

Here, we will be discussing something that is crucial when it comes to planning a home extension – budgeting. We understand that home extensions are exciting projects, but it's important to ensure that you have a well-defined budget in place for a smooth and successful project. In this article, we will focus specifically on the importance of budgeting for surveyors' fees and the notification time periods that can affect your project costs.

Surveyors Fees

One of the key aspects of budgeting for your home extension is considering the fees of a party wall surveyor. Hiring a party wall surveyor is essential when carrying out any construction work that affects a shared wall between two properties.

It ensures that both you and your neighbour are protected and that everything is carried out according to the law.

The fees for party wall surveyors in London typically range from £90 to £200 per hour, with an average cost of £175 per hour, plus VAT (although there are surveyors who will charge significantly more than this!). The actual costs can depend on various factors, including the size of the project, the location, and the experience of the surveyor.

While the fees may vary depending on the complexity and size of your project, it's crucial to allocate a portion of your budget to cover these costs. By budgeting for these fees, you will be able to work with an experienced surveyor who can guide you throughout the process, offering advice and ensuring that all legal requirements are met. Having a professional surveyor on board will provide you with peace of mind, helping to avoid any potential issues that may arise during or after the construction.

Notification Time Periods

In addition to surveyor’s fees, it's highly important to consider the notification time periods that are associated with a party wall agreement. When planning your home extension, it's essential to understand and comply with the legal obligations of notifying your neighbours in advance.

Failing to provide the necessary notice within the specified time frames can lead to delays, disputes, and even increased costs. These time periods can vary depending on the nature of the work you are carrying out. For certain projects, you may need to notify your neighbours at least 2 months prior to starting the

construction process. However, this can vary, so it's important to consult with a qualified surveyor to ensure you are aware of the specific requirements for your project.

By budgeting for these notification time periods and ensuring you adhere to the legal obligations, you can avoid additional expenses that may arise due to delays, legal disputes, or the need to make changes to your original plans. It's important to stay organized, plan ahead, and factor in these time frames while creating your budget to guarantee a smooth and cost-effective home extension project.


Budgeting for your home extension project is essential, and understanding the key aspects of budgeting, such as surveyor's fees and notification time periods, is crucial for a successful outcome. By allocating funds for surveyor's fees and accounting for the necessary notification periods, you can avoid unexpected costs and potential disputes, ensuring a seamless and enjoyable experience throughout the expansion of your home.

Remember, planning and budgeting are vital parts of any home extension project. By taking these steps, you can lay the foundation for a successful project and create the dream space you've always envisioned. Happy home extending!

Note: Please keep in mind that party wall surveyor's fees can vary, and the ranges and costs given here may not be applicable to every situation. It's always best to consult with a qualified surveyor to get an accurate estimate based on your specific project details.
