✍️ Bio
Thomas Penfold, BEng (Hons) MSc
Principal Structural Engineer
With over a decade of experience in residential structural engineering, Thomas has worked on hundreds of domestic projects — from beam designs and loft conversions to structural reports and site inspections.
He founded TWP Engineering Services to deliver high-quality, approachable engineering support to homeowners, architects, and builders across the South.
“I believe in making engineering understandable, approachable, and efficient for everyone involved — especially at the domestic scale.”
