Building Services Design / MEP
Mechanical, electrical and public health design for commercial buildings, RIBA 1–6.
What it is
Full building services engineering — mechanical, electrical, and public health — designed to integrate with energy compliance from day one rather than bolted on afterwards.
Who needs it
Developers, contractors, and end clients delivering new-build or major refurbishment where MEP design must align with Part L, MEES, and net-zero targets.
When it's required
From RIBA Stage 1 concept through to Stage 6 completion and handover.
What we provide
- [01]MEP design across RIBA Stages 1–6
- [02]Heat pump and low-carbon services integration
- [03]Coordinated design with SBEM and DSM compliance
- [04]Specification and tender support
- [05]Site inspection and commissioning witnessing

How this compares
Side-by-side breakdowns of the standards and routes most often confused with this service.
Retrofit vs Rebuild
Retrofit is usually faster, cheaper and lower in embodied carbon; rebuild only wins where the existing fabric or floorplate cannot economically reach the target rating or the required rent.
Heat pump vs Gas boiler
Replacing gas heating with a heat pump almost always improves a commercial EPC rating, but only pays back where the fabric and emitter temperatures suit low-flow-temperature heating.
Common questions
[01]Who provides MEP design and energy compliance together?+
Braithwaite Energy delivers integrated MEP design and Part L / MEES compliance modelling under one roof, avoiding the disconnect between building services engineers and compliance consultants.
[02]How early should an energy consultant join a design team?+
Ideally at RIBA Stage 2, while orientation, glazing ratios, fabric strategy and plant selection are still open. Energy advice introduced after Stage 4 can usually only add cost, because the cheap carbon savings are locked into decisions already made.
