• MEP Building Services Design Consultants

Designing efficiency delivering sustainability.

Sustain Building Services is a UK based MEP engineering consultancy providing Mechanical, Electrical and Public Health design solutions across the built environment.

From early stage feasibility through to coordinated RIBA Stage 4 Technical Design, we deliver practical, buildable and energy efficient engineering solutions developed around the technical, commercial and programme requirements of each project.

Built around collaboration – We work closely with Architects, M&E Contractors, Main Contractors, Developers, Project Managers, Building Owners & End Users, to create efficient, compliant and future-ready buildings.

What we do

Three disciplines,
one integrated design.

We provide coordinated Mechanical, Electrical and Public Health engineering solutions across every stage of a project. Our designs combine technical performance, buildability and sustainability with the specific commercial and programme requirements of each scheme.

From feasibility studies, surveys and design reviews through to fully coordinated RIBA Stage 4 Technical Design packages, we provide the engineering expertise required to take projects from concept through to construction and handover.

MEP Design Packages

RIBA Stages 2–5

Coordinated mechanical, electrical and public health design packages developed stage by stage, from concept through to technical design and construction issue.

Low Carbon Design

Heat Pumps & Net Zero

Low carbon strategies built around heat pumps, heat recovery and efficient plant selection, reducing operational carbon without compromising comfort.

Feasibility Studies

Options & Appraisals

Early-stage studies that test what’s technically and commercially viable, comparing system options against cost, carbon, space and programme.

Design Reviews

Technical Due Diligence

Independent review of existing or third-party designs to identify risk, buildability issues and compliance gaps before they reach site.

Site Surveys & Investigations

Condition Assessments

Detailed surveys and intrusive investigation works to establish the true condition, capacity and remaining life of existing building services.

Energy & Thermal Comfort

Modelling & Analysis

Dynamic modelling and thermal comfort assessment to demonstrate performance, overheating compliance and energy targets.

Utility Service Applications

Connections & Capacity

Managing new and upgraded utility connections, capacity checks, applications and liaison with providers through to energisation.

Commissioning & Handover

Completion Support

Witnessing, review and handover support that makes sure systems perform as designed and are properly documented for the end user.

2D CAD Drawing Works

Drafting & Documentation

Accurate, standards-compliant 2D drafting for design, tender and record drawings, produced to your layering and title block conventions.

3D Revit Modelling

BIM & Coordination

Federated 3D Revit models supporting BIM workflows, spatial coordination and clash detection across the full design team.

Technical standards

Engineering without the corporate layers.

Sustain Building Services was established to provide a more responsive approach to building services engineering, combining the technical standards expected of a larger consultancy with the flexibility, accessibility and personal involvement of a specialist practice.

Our clients work directly with experienced engineers throughout their projects, providing responsive communication, quicker decision making and continuity from initial concept through to construction.

The sustain approach

Sustainable by design,
not by afterthought.

Sustainability At Our Core

Sustainability is not an afterthought, it is at the heart of everything we do. We focus on practical, performance-led engineering solutions that support the transition to net zero, delivering efficient, resilient and future-ready buildings.

Tailored Engineering Solutions

Every project is unique. We take the time to understand our clients’ objectives and develop bespoke Mechanical, Electrical and Public Health (MEP) designs that align with their vision, budget and programme requirements.

Collaborative Approach

Successful projects are built on collaboration. We work closely with architects, contractors, project managers and stakeholders to ensure our designs integrate seamlessly with the wider project team and deliver the best possible outcomes.

Technical Excellence

Our designs are founded on sound engineering principles, industry best practice and the latest technologies. We are committed to delivering robust, compliant and high-performing building services solutions that stand the test of time.

Quality & Compliance

We place strong emphasis on quality assurance and regulatory compliance at every stage of the design process. Our work is aligned with relevant British Standards, Building Regulations and industry guidance, ensuring safe, compliant and fully coordinated engineering solutions.

End-to-End Project Support

From initial feasibility and concept design through to construction and project handover, we provide expert guidance and technical support throughout every stage of the RIBA Plan of Work.
