Extending your home is an exciting project that can improve the functionality of your property and add significant value too. In fact, according to research by Zopa, the average amount of profit generated by a home extension is £14,000! However, choosing the right local extension builders is crucial to ensure a smooth process and a result that matches your vision. With so many options out there, it’s important to know what to look for and the questions to ask to ensure you make the best choice.
This guide, compiled by the expert property developers at Fleet Homes Construction in Hampshire, will walk you through the steps to find the right local extension builders for you. Simply read on to learn how to avoid common pitfalls, ensuring a successful extension project.
Before you start looking for local extension builders, it's essential to have a clear idea of what you want from your extension.
Consider the purpose of the extension - whether it’s to create more living space, add a new bedroom, or open up your kitchen - and think about how it will integrate with your existing home. Setting a clear vision helps you communicate effectively with potential builders and ensures they understand your goals from the outset.
Create a detailed brief outlining your expectations, including the desired size, style, and specific features of the extension. This document will be invaluable when discussing your project with builders, as it ensures everyone is on the same page. Remember, the clearer you are about your requirements, the easier it will be for local extension builders to provide accurate quotes and timelines.
Once you have a clear vision for your project, the next step is to research and shortlist potential local extension builders. Start by looking for builders in your area who have experience with projects similar to yours. Choosing local extension builders who are familiar with local regulations and building codes can save you time and reduce the risk of complications down the line.
Check online reviews and ask for recommendations from friends, family, or neighbours who have undertaken similar projects. Websites like Checkatrade can provide valuable insights and reviews from other homeowners, helping you identify reputable builders. Aim to create a shortlist of three to five builders to contact for initial discussions and quotes.

Once you’ve shortlisted a few local extension builders, it’s time to dig deeper by asking the right questions during initial meetings. This step is crucial for gauging their experience, reliability, and suitability for your project. Here are some key questions to consider:
Transparent communication and setting realistic expectations about timelines and costs are key to a successful partnership with your builder.
One of the most important steps in choosing local extension builders is verifying their credentials. This ensures that the builder is qualified and meets the necessary legal requirements to carry out your project.
Check that the builder has the appropriate insurance, such as public liability insurance and employer’s liability insurance, which protects both you and the builder in case of accidents or damage during the project.
Additionally, look for builders who are members of professional bodies such as the Federation of Master Builders (FMB). Membership in such organisations often indicates a commitment to high standards and quality work. The FMB’s ultimate guide to house extensions provides further information on what to look for in a qualified builder.
Don’t hesitate to ask the builder to provide proof of their credentials. A reputable builder will appreciate your diligence and be happy to provide the necessary documentation.
Once you’ve verified the credentials of your shortlisted local extension builders, the next step is to obtain detailed quotes. It's recommended to get at least three quotes to compare prices and understand what each builder includes in their offer. Be sure that each quote is comprehensive, covering all aspects of the project, including materials, labour, and any potential additional costs.
Pay close attention to the level of detail in each quote. A good quote should break down costs clearly and provide a realistic timeline for the project. If a quote seems unusually low compared to others, it might be tempting to choose the cheapest option, but be wary - this could be a sign of cost-cutting on materials or a lack of experience.
Ensure that the quotes are based on the same scope of work for a fair comparison. This will help you identify any significant differences in pricing and make an informed decision about which builder offers the best value for your investment.

Choosing the right local extension builders is not just about finding the best price; it’s also about avoiding the pitfalls that can lead to a poor experience. Here are some red flags to watch out for:
