Book a Consultation

Speak to our experts

Do you have specific queries on a project or want some independent advice – or perhaps you have a specific project in mind? If so, book a consultation with one of our specialists to talk about your project. We can offers consultations on moisture risk, building services and Passivhaus and retrofit.  

If you’re not sure, then use our FREE 15 minutes general consultation to talk through what you would like to achieve and how we can help.  We will provide independent advice on planning your project and technical advice to help you get started

Our initial consultation sessions are designed to provide you and your client with real value from the very beginning. During the 60-minute consultation, we will assess your goals, identify potential challenges, and offer professional guidance tailored specifically to your project to ensure our advice is genuinely useful and aligned with you and your client’s needs. This gives you and your client the opportunity to ask questions and ensure the scope is clearly defined before any formal proposal is prepared. Rather than simply discussing ideas at surface level, we provide actionable insights based on years of hands-on industry experience.

Before any successful project begins, it is essential to start with the right expertise and strategic direction. With over two decades of experience in our field, our team brings specialised knowledge, technical insight, and practical problem-solving skills that help clients avoid costly mistakes, delays, and inefficiencies.

Consultations are available for the following topics:

Whilst these initial consultations are chargeable, for a comparatively small investment this ensures that your project starts on a solid foundation, with clarity, direction and expert input that can ultimately save both time and resources.
