Family-run commitment
SM Energy Group is a family-run establishment based in Rothwell (LS26). We answer our own phones, attend our own surveys, and stand behind every job long after the installation is complete. Our reputation in Leeds, Wakefield and across Yorkshire is built one home at a time — that's why repeat work and word-of-mouth referrals make up the majority of our calendar.
