We provide a level of personal attention, which is not achieved by larger organisations, whilst providing the breadth of experience, technical skills, strength of resource and management ability which cannot be offered by smaller building services consultancies. Each consultancy project is approached without pre-conception, creating an environment for innovative design.
We are also able to offer both Sustainable & Energy Efficient Solutions including Dynamic Simulation Modelling (DSM), SBEM Calculations, Energy Performance Certificates (EPC’s), Display Energy Certificates (DEC’s) as well as full Sustainability Reports. We have formed close links with external BREEAM Assessors and can offer this service if required.

Our Story

The company was formed in 1986 by Stanley Lumb & Stuart Thornley with the aim of bringing a fresh approach to Mechanical & Electrical Building Services Engineering. The company has grown organically due to the time and effort put into dealing with clients on a personal level, ensuring that where any issues arise they are dealt with and actioned swiftly, This has lead to at least 80% of our work being repeat business from our ever expanding client base.

The company underwent a Management Buyout in 2006 and is now being operated under the Directorship of Martin Thornley and Graham Powell with the sole aim of maintaining and improving our high standing within the Building Services Consultancy sector.

Thornley & Lumb Partnership Ltd is based in Bradford West Yorkshire where we have a total staff of 20, this being a mix of Mechanical & Electrical Senior / Intermediate & Junior Engineers.

Our current range of projects are spread throughout the UK with a large number of projects within and around the M25 circle, and other projects spread from Exeter in the South to Aberdeen in the North, Bridgend in Wales and Lowestoft in the East and all points between.

As part of Thornley and Lumb’s commitment to standards we have been a registered company since 1999, and currently hold the BS EN ISO 9001 :2000
