Lùths Services is an independent Building Services Engineering consultancy based in Glasgow – we work all over Scotland.

We only do “sustainable design” projects- We have a particular expertise in energy efficiency, low carbon, healthy buildings and renewables.

Our passion is for “data driven design”. This allows you to reduce your uncertainty and build costs with accuracy.

Finally we like to use “practical design” – whether you need a feasibility assessment or are already onsite we can provide a rational and practical link between abstract designs and real life build issues.

*Lùths is the Gaelic word for “Energy“.

Building Services-Consulting Engineers- Detailed Design

Building Services are ever more complex and in particular with rapid uptake of novel low energy and renewable technologies there is significant benefit from employing an M&E Consulting Engineer who has experience to deliver a building that can meet your demands without compromising the energy and carbon budget for the building.

Post Construction Compliance

The end of a project can use M&E Consulting Engineers -independent engineers to verify works done or assist in setting them up properly (heating, heat pumps and ventilation). We can do the final paper work (Energy Performance Certificates [EPC] and Air Tightness Testing if needed). Finally you may want help with grant applications (such as Renewable Heat Incentive).
