FAQs

What is M&E building services engineering?

M&E services engineering is essential to meeting the specific needs of modern building design. It ensures that systems for heating, ventilation, lighting, power and fire safety are effectively planned and installed to make buildings safe, comfortable and energy-efficient.

Do you handle both public and private sector projects?

Yes, we work with local councils, housing associations, commercial developers, and private contractors in various industries across Scotland.

Can you work on retrofit or decarbonisation schemes?

Absolutely. We support the entire process of retrofit and decarbonisation schemes, from early planning through to installation and completion. Our team delivers energy upgrades such as heat pumps, solar PV, insulation and smart controls, helping clients improve building performance and work towards Net Zero targets with confidence.

Do you provide M&E services for CAT A and CAT B commercial fit-outs?

Yes, we do. James Frew delivers mechanical and electrical services for both CAT A and CAT B fit-outs across a wide range of commercial spaces.

CAT A Fit-Outs involve installing core building services such as lighting, power distribution, heating and ventilation systems to prepare the space for occupancy.
CAT B Fit-Outs focus on tenant-specific features like breakout area ventilation, security systems, data cabling and bespoke lighting or power requirements — tailored to business day-to-day operations.

So, whether you’re a landlord preparing a unit for lease or a tenant customising the space for your team, we can provide support to suit.
