Why choose an NABC builder

The National Association of Building Contractors logo is recognised by consumers and home owners throughout the UK. It is respected as a sign of professionalism and a commitment to excellence in the home improvement sector. As part of your memberships we have strict standards on how we expect our members to conduct their business. These standards centre around fairness, transparency, honesty and quality of service.

Working with your builder

Having an extension built on your house can be one of the most exciting projects you may ever take on. But you’ve taken the plunge, had plans drawn up and planning permission has been given. Now is the daunting task of finding a builder. Don’t be put off by all the publicity about cowboy builders. It wouldn’t be news if all builders were the same. The large majority of builders are reputable and will do a good job on your building work.

What Our Customers Say

I used National Association of Building Contractors to find a builder to build my extension and cannot speak highly enough of them both professional and personable and could not be happier. The extension to look as good as it does! It’s refreshing to see a company not focusing purely on profit or costs.
Emily Hunt

Extension

A great experience start-to-finish! Paul, Sarah and the team were an absolute pleasure. The job felt well-organised and the builders clearly runs a tight ship as everything ran on schedule. We’re so pleased with the quality of the work and the results. In fact, when Building Control came to sign off the work the inspector commented that the work was done to a really high standard. Can’t get better than that!

Garage conversion

I used a builder Dunn and Michaels from South London to complete our extension. I am completely satisfied with the job carried out. The process was faultless from start to finish. Professional in all. Aspects if the job. I would highly recommend NABC to anyone.
