About Us

Established in 1979, Colin Lynch Builders has a long and proud trading history in Enfield and throughout North London. Our company’s proprietors are Colin and Paul Lynch. Colin formed the company, and Paul now runs it to the same unmatched standards. We pride ourselves on the amount of trade we receive through repeat customers and our reputation for excellence. In fact, many of our customers span multiple generations.

As a smaller, family-run business, we dedicate all our resources and time to your specific project and never fluctuate between jobs. This not only allows us to fully focus on producing the best possible service and results for you, but it also keeps the risk of delays and disruption to an absolute minimum.

For larger jobs like house extensions and loft conversions, we offer a complete end-to-end service that ensures the project runs to an efficient conclusion. In the pre-build phase, this involves help with the design or working with a designated architect of your choosing.

During the physical build, your site manager will be at your property for the duration, giving you a constant point of contact for any queries you may have. Of course, we also provide regular progress updates too, so you’re never in the dark about the work taking place at your home.

For customers’ peace of mind, our team holds various industry-leading credentials, including:

  • Federation of Master Builders Membership

  • Build Assure-Certified Company

  • TrustMark Registration

  • Which Trusted Trader

  • FENSA-Certified Installers

  • LABC Registration

  • EBC Membership


With more than 40 years of industry experience, and having been externally assessed to the highest industry standards, your project is in safe hands with us.
