FENSA Approved Installers

At DK Building we pride ourselves on being a fully compliant, professional building company dedicated to delivering high standards and peace of mind for our clients. One of the key ways we demonstrate this commitment is through our partnership with FENSA. As a FENSA Approved Installer — a government-authorised scheme that ensures compliance with building regulations for replacement windows and doors — we uphold the highest standards in our work.

Why FENSA Matters

FENSA ensures that every installation we carry out meets strict building regulations, is energy efficient, and is properly registered with the local council. When you choose a FENSA Approved Installer like us, you get that reassurance.

We understand the importance of structural integrity and energy efficiency firsthand. For example, during a recent window replacement project, we addressed a lintel issue with careful assessment and precision. As a versatile general contractor capable of handling a wide range of projects, we adopt a “one company does it all” approach. We meticulously evaluate each structure, select the appropriate materials, and ensure that every installation complies with all relevant regulations. This hands-on experience underscores our commitment to quality, safety, and providing peace of mind for our clients.

Our work is assessed regularly by FENSA , which is one of the important parts of the certification agreement. Our installations comply with energy standards, helping you save on energy bills. We handle all registration processes on your behalf.

Why Clients Choose Us

Many clients come to us because they’ve encountered missing building control certificates or are unsure if their previous work meets current standards. We’re proud to say that we’re close to full compliance across all areas—electrics, gas work, windows, and soon, MCS certification. Our goal is to be your trusted partner who can provide all necessary certificates, saving you time and hassle.

As a FENSA-Approved business, we undergo rigorous assessments to maintain our standards. Our team holds an MTC Competency Card, and we are IBG (Home Improvement Protection) providers. We also offer Insurance Backed Guarantees and Deposit Protection, giving our clients comprehensive peace of mind.
