New Build Mechanical & Energy Packages for Cork Builders & Developers

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.

Mechanical Systems We Install in New Builds

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.

First & Second Fix Plumbing

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.

Air-to-Water Heat Pump Systems

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.

Underfloor Heating

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.

Solar PV Systems

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.

Mechanical Ventilation (MVHR)

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.

Full Insulation Packages

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.

Hot Water Systems

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.

Central Heating Distribution

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.

Who We Work With

We work directly with all parties involved in the construction process:

  • Builders & Construction Firms

    Main contractors and sub-contractors seeking a reliable mechanical partner for residential and commercial projects

  • Developers

    Housing estates, apartment complexes, and commercial developments across Cork

  • Architects & Engineers

    Design teams requiring a mechanical contractor who can deliver on specification

  • Self-Builders

    Homeowners managing their own build who need expert guidance on mechanical systems

Why Use One Mechanical Contractor?

Managing multiple trades for mechanical services creates coordination problems. With CEL Energy handling everything, you get:

  • Fewer coordination headaches — one point of contact, one schedule to manage
  • Guaranteed system integration — heat pump, UFH, MVHR, and plumbing designed to work together
  • Single point of accountability — one contractor responsible for the complete mechanical package
  • Faster completion — no waiting between trades, no clashes between different installers
  • Clearer problem resolution — if something doesn't work, there's one company to call

Building Regulations

Part L Compliance & NZEB Standards

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.

How We Ensure Compliance

  • We carry out SAP calculations early in the design stage to confirm your systems will meet the required targets
  • All insulation and airtightness work is installed to specification before air permeability testing
  • We provide all commissioning documentation and system certificates required for Part L sign-off
  • Heat pump, MVHR, and solar PV systems are commissioned by qualified technicians

Our New Build Process

From initial design to final handover
