Design and Specification Service

At Clean Air Direct, we offer a Ventilation System Design and Specification Service to provide you with the highest level of specification support for your ventilation installation. Whatever your ventilation needs - from existing building upgrades, rented property and social housing indoor air quality compliance, through to new build projects - our design service can take the headache out of choosing the right system.

If you are a Homeowner, Self-Builder or Landlord looking to install a mechanical ventilation system; a Builder, Plumber, or Electrician, looking to add mechanical ventilation installation to your portfolio of services; or an Architect/Developer looking to sidestep the distinct hurdles encountered while integrating efficient ventilation systems into plans, concepts, and approved designs, this service is for you.

Contact Us To Start Your Specification Journey

Initial Consultation


We are committed to finding the right ventilation system for you, from upgrading basic extractor fan units through to whole house MVHR heat recovery ventilation. Our experienced team will work with you via email and over the phone to ascertain the correct system type you require, taking into consideration your budget, requirements, and suitability to meet your
particular needs.

We will produce a system quotation for you based on the information provided during this consultation.

System Design and Quotation


Following the initial consultation process, our design team will produce your specification and quotation. Depending on the type of system identified we may require structural plans or construction blueprints
and, working alongside the system manufacturer, we may also conduct a site visit to produce your bespoke design to meet both installation and regulation requirements for the project. These plans can be used by your installer as an installation guide and will allow us to quote for the precise items needed, so that your system comes complete with the required products to install your new system as efficiently as possible.

Continued After-Sales Support


Once you have received your new system, both you and your installer will receive ongoing support throughout the installation process to help with any queries that may arise.

Your system comes backed with a guaranteed 5-year
warranty which will also cover support from the manufacturer should you require assistance further down the line.

Is this service for me?

Whether for a new-build project, renovation or simply a ventilation upgrade for an existing property, our design service offers tailor-made mechanical ventilation solutions made to seamlessly integrate with your installation needs.

Our service handles everything other than fitting, offering a complete ‘hand-holding’ service from initial consultation through to the delivery of your system and includes technical support directly from the system manufacturer to support your installer if needed.

Our packages are tailored to accommodate any residential project. With detailed and adaptable designs, we guarantee a seamless fit, project after project, eliminating the need for guesswork.

As the need to construct homes with enhanced performance to meet rising efficiency standards, Building Regulations continue to advance, becoming more stringent. Failing to meet these standards is not an option, particularly if your aim is to deliver a seamless project on schedule and on budget. Our ventilation solutions are meticulously crafted to not only meet but surpass local Building Control stipulations, such as minimum air flow rates, fire cover and overheating cover, guaranteeing that your project is fully compliant to smoothly pass inspections without incurring expensive delays or revisions. 

Central to our designs is a dedication to enhancing the well-being of you and your family. Through the enhancement of air quality and the provision of a comfortable living environment, our mechanical ventilation with heat recovery (MVHR) or Mechanical Extract Ventilation (MEV) systems actively contribute to improved health and productivity. As well as an array of other ventilation system options, allowing us to present the best fit for your ventilation requirements

As a developer/Installer, our clear and concise support materials, including manufacturer’s installation guidelines and design drawings, coupled with dedicated support resources, empower you to concentrate on delivering top-tier systems to your clients.

Our designs deliver sustainable standards, guaranteeing that your design adheres to both compliance requirements and eco-conscious principles, whilst delivering cost-effective mechanical and heat recovery ventilation designs that meet any budgetary constraints without sacrificing performance.

Our designers prioritise "optimal occupant comfort" by specifying the most suitable systems, whether advanced heat recovery ventilation systems, ventilation only or positive pressure systems are applicable, ensuring superior air quality and comfort and thereby enhancing the well-being of both the building and its occupants.

Our commitment to excellence extends beyond the design phase with support throughout the installation process and beyond, guaranteeing that your ventilation system is not only fitted correctly but also operates at peak performance levels.
