CEL Energy Ltd delivers complete mechanical and energy packages for new residential and commercial builds across Cork. From first-fix plumbing and heat pump systems to solar PV, underfloor heating, and MVHR — we handle every element under one contractor.
Working with builders, developers, and self-builders, we ensure every installation meets Irish Part L requirements and achieves the BER rating your project needs.
Every new build requires a coordinated approach to mechanical services. We design and install each system to work together, optimising performance and ensuring compliance with Part L building regulations.
Complete pipework installation from builder's stage through to finished fixtures. We install all cold water, hot water, and central heating distribution pipework. Proper first-fix planning prevents costly amendments at second-fix stage.
Modern heat pumps provide space heating and hot water with significantly lower running costs than oil or gas boilers. We size and specify systems to achieve the SAP calculations required for your BER certificate.
UFH delivers even, comfortable heat distribution while freeing up wall space. We install both screen-printed heating mat systems for screed applications and low-profile panel systems for installations where floor height is limited.
Grid-connected solar panel arrays reduce electricity bills and contribute to Part L compliance. We install systems with battery storage options and smart monitoring, ensuring optimal self-consumption and export balance.
Heat recovery ventilation maintains air quality while retaining up to 90% of exhaust heat energy. Essential for airtight new builds, MVHR systems are often required to meet the specific ventilation rates in Part L.
Wall, floor, and roof insulation must achieve precise U-values to satisfy Part L and reach target BER ratings. We coordinate with the build programme to ensure insulation is installed correctly before airtightness testing.
From indirect cylinders paired with heat pumps to solar thermal arrays, we install hot water solutions sized for household demand. Correct cylinder selection directly impacts SAP calculations and overall BER rating.
Radiators, towel rails, and thermostatic controls distributed throughout the property. We design heating zones to balance comfort, efficiency, and the energy demand calculated in your SAP assessment.
We work directly with all parties involved in the construction process:
Main contractors and sub-contractors seeking a reliable mechanical partner for residential and commercial projects
Housing estates, apartment complexes, and commercial developments across Cork
Design teams requiring a mechanical contractor who can deliver on specification
Homeowners managing their own build who need expert guidance on mechanical systems
Managing multiple trades for mechanical services creates coordination problems. With CEL Energy handling everything, you get:
All new builds in Ireland must comply with Part L of the Building Regulations, which implements the Nearly Zero Energy Building (NZEB) standard. This means every property must meet strict energy performance requirements before it can be certified for occupation.
For mechanical systems, Part L sets specific requirements for heating system efficiency, insulation U-values, solar renewable energy contribution, and ventilation. The BER (Building Energy Rating) certificate — rated from A1 to F — quantifies how well your property performs. New builds must achieve a minimum BER rating as specified in the current Technical Guidance Document L.
From initial design to final handover
We review the architectural drawings and advise on the most efficient mechanical package for your target BER rating.
Heat loss calculations, pipe sizing, and system layout are designed to work within your BER targets.
All pipework, ducting, and cable routes are installed during the structural build stage.
Fixtures, appliances, and controls are installed and fully commissioned with documentation.
Final checks, commissioning certificates, and support for BER assessor submissions.
