Integrated mechanical and electrical engineering services

We have built up a strong reputation for the professionalism of our engineers, our pragmatic approach, and our focus on maximising energy efficiency.

You can trust us to deliver cost-effective and integrated electrical mechanical engineering projects that will meet their budget and run efficiently, with minimal energy wastage. Below are just a few of the many considerations we take on board with any project we are involved with.

Project management

It’s imperative that the electrical and mechanical installation process is managed effectively, we maintain a 100% track record of delivering projects on time and on budget.

Our knowledgeable and creative engineering team are both skilled and experienced in delivering complex integrated electrical and mechanical services installations.

Building requirements

When we embark on a mechanical and electrical engineering solution.

We consider the requirements of the environment within the building, and how that environment can be best implemented in a sustainable manner to optimise the working processes and activities within the building – whilst also promoting the health and wellbeing of the occupants.

Energy sources

We assess the best sources of available energy that are suited to the type of project, whether it be biomass boilers, ground or air source heat pumps, photovoltaic electricity, or harvested rainwater, and with our mechanical and electrical design experience, we can make suitable recommendations.

Night cooling and purging may or may not be appropriate. Some buildings are suited to being naturally ventilated, others may need to be mechanically ventilated for acoustic reasons.


Our knowledge of the latest technology and the solutions available within the marketplace.

This means that we can assess the aesthetics of the space and formulate an effective electrical and mechanical services solution to minimise the visual effect of engineering services.

Planning ahead

Not only do we take care of the visible engineering.

We also take equal care of the concealed electrical and mechanical services that support the building operation, planning common service routes, carefully making use of the available void space to assist with future maintenance.

Green technology engineering

Integral to any of our design solutions is our focus on reducing the environmental impact of the building.

We have advocated the use of green technology engineering for many years, promoting the improvements in building construction to minimise heat loss, maximise heat retention, and position windows in a manner to make best use of natural light.

Intelligent technology

Finally, we automate the electrical and mechanical services using intelligent technology, designed to offer maximum system operation and flexibility within an interface which focuses on ease of use.

Services are designed to work effortlessly when they are needed, to maintain a comfortable environment, modulating to save energy where possible or appropriate.

Maintenance of electrical and mechanical services

Once we have designed and installed a completely integrated electrical and mechanical services system, we are able to offer maintenance contracts to ensure equipment is regularly serviced and maintained, to keep it running at maximum efficiency and to rectify any potential issues before they arise.
