While much of our work is direct for private clients with smaller projects, we work equally well - and to equally high standards - with Architects, Surveyors and Interior Designers. You will find when we work together that we have a great deal of respect for each member of the building team. Our driving goal is the creation of a successful, co-operative relationship where each member of the team will enjoy the chance to work together on a successful project.


We enjoy working with Architects

When working with Proficiency you will work with a company that understands what quality really means. You will appreciate the unusually high level of professionalism, quality workmanship and integrity you will find here. To say nothing of the friendships that often develop as we work together.

For your reference, we welcome:

  • All types of residential remodelling, extension, alterations and upgrade projects. Good quality and high-end work is our real love.
  • New-build and extension works
  • Contract values from under £50,000 to £1m
  • Work on sites within an hour or so of our Finchley offices – that’s most of north London
  • We also welcome commercial and community-type work from churches and surgeries through to leisure and Care works.

Total commitment and fine trades

Like yourself, we fully understand that every successful project requires 100% commitment in order to deliver the best possible building for the client. We work hard and we are not prepared to compromise quality. Residential projects can get complex, and that requires very capable trades professionals who can think on their feet and who have a rich background in all forms of training including safety on site, safe use of tools, dedicated waste management and work at heights for example.

A full team including design and interiors

Unusually, Proficiency has a full complement of designers and trades. If required, we can complement and support the Architects we work with using our in-house design and interior design resource. Then on site, virtually every trade will be one of our direct trades – from bricklayers and carpenters to plumbers and electricians. Many of these have spent the greater parts of their professional lives perfecting their trade, amassing priceless knowledge and wisdom that they apply upon every project.

What you can expect from us:

  • Fully detailed tenders with precise breakdowns on material and labour costs
  • A total commitment to return a price if we accept a tender
  • Financial transparency and an ability to think outside the box when we work with you on cost-reductions on tenders above budget for example.
  • Full insurance on an all-risks basis; details to request
  • Professional and friendly design support for contractor-designed elements or full design/build projects.
  • A total commitment to completing every project on time and on budget.
