Trusted by homeowners, developers, and housing associations across the UK for professional ventilation design, installation, and ongoing maintenance. Our NICEIC-certified team brings deep technical knowledge and a commitment to indoor air quality that sets us apart from general tradespeople.
While general electricians and plumbers may fit fans, Flexivent specialises exclusively in the science of airflow. Proper ventilation requires precise design, ducting calculations, and commissioning to ensure your system is quiet, efficient, and compliant. We don't just bolt it to the wall; we engineer it to work for your specific property.
Every home is different, and so is every ventilation solution we deliver. We carry out a thorough property survey to assess room volumes, occupancy levels, moisture sources, and existing building fabric before recommending the right system. Whether you need a whole-house MVHR for a new-build, a retrofit PIV to tackle condensation in an older property, or a cMEV system for a multi-storey flat, our engineers will design a solution that balances performance, energy efficiency, and budget.
Our NICEIC-registered engineers hold specialist qualifications in domestic ventilation design, installation, and commissioning. Every team member undergoes continuous professional development to stay current with the latest MVHR, MEV, and PIV technologies from leading manufacturers like Zehnder, Vent-Axia, and Nuaire.
We provide transparent, itemised quotations before any work begins, so there are never hidden charges or unexpected costs. Every quote includes a full breakdown of equipment, materials, labour, and commissioning, giving you complete confidence in the investment you are making in your home's air quality.
After every installation and service visit, you receive a comprehensive digital report documenting system performance, airflow measurements, filter condition, and any recommendations. Our commissioning certificates confirm your ventilation system meets Part F Building Regulations and manufacturer specifications.
From London and the South East to Scotland and the Midlands, our network of local ventilation engineers ensures responsive service wherever you are in the UK. We handle projects of every scale, from single-dwelling PIV installations to multi-unit MVHR fit-outs on new-build developments.
We understand that ventilation issues affect your comfort and wellbeing. That is why we offer priority booking with rapid response times, including same-day availability for urgent callouts. Our engineers carry a comprehensive stock of common filters, parts, and replacement units to resolve most issues in a single visit.
Every Flexivent installation is designed and commissioned to satisfy Approved Document Part F of the Building Regulations, as well as manufacturer warranty requirements. We provide all necessary documentation for building control sign-off, ensuring your property meets current ventilation standards for indoor air quality and energy efficiency.
Electrical safety is a statutory requirement for landlords and business owners across the UK. Under the Health and Safety at Work Act 1974 and the Electricity at Work Regulations 1989, it is the duty of the 'Responsible Person\' to ensure electrical installations are maintained in a safe condition.
Our City & Guilds qualified engineers provide comprehensive EICR (Fixed Wire Testing) and PAT testing services that identify hidden defects before they become hazards. From commercial thermographic surveys that detect overheating components to emergency lighting testing for fire safety compliance, Flexitest Ltd delivers the quality reporting and remedial works needed to keep your property insured and your people safe.
