UKPC Construction is by far the best company I have ever worked with, and I highly recommend them to anyone. Their team is not only courteous and professional but also a breeze to work with. They expertly helped me transform my jungle-like garden, and although I'm writing this review after some time, I'm now looking forward to discussing the extension project they initially designed with me. A big thank you to UKPCC, and I wholeheartedly endorse their services to everyone.

What to ask a Islington extension builder before hiring?

Before hiring an extension builder in Islington or extension building company in Islington, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Islington?

An extension builder in Islington should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Islington extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Islington?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Islington extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Islington extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
