Sheffield is built on hills: terraces in Walkley and Crookes, post-war estates further out, and a lot of steep, awkward access. Cold winters up the valleys keep heating work busy. For a heating engineer, that means boiler installs, heat pumps and servicing that cannot be put off. Areas that generate the most call-outs: Crookes, Walkley, Hillsborough, Ecclesall, Nether Edge.
