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.

Latest review:
Source FM recently helped us fit out a new 8000 sq ft warehouse in Hackney. The project included installing new electricals, installing new fire and security alarms, repairing and repainting a heavily used concrete floor, redecorating, servicing the heating etc. The project had a very tight time frame and Source FM often had to work around members of our team as we started moving in while work was still ongoing. I'm pleased to say, all the work was completed in time and to a very high standard. We've since used Paul and Bill for a number of smaller projects, both at the warehouse and in our offices.

What to ask a Clerkenwell extension builder before hiring?

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

An extension builder in Clerkenwell 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 Clerkenwell 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 Clerkenwell?

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 Clerkenwell extension builder’s ability to deliver a result that meets your expectations.
