Victorian & Edwardian terraces
Combis in kitchen cupboards, old regular boilers with tanks in the loft, and radiators that have seen a century of sludge.

9 cities, one standard
Why Rossi
British boilers don’t fail politely. The pressure drops on the coldest night of the year, the condensate pipe freezes on Christmas Eve, the gas safety record runs out the week new tenants arrive. Our job is to make the fix feel simple.
Who we are
Heating engineers for old buildings and new rules.
A single British street can hold a Victorian terrace with a thirty-year-old boiler, a loft conversion that bakes every July, and a new-build flat heated by a plant room nobody has seen. Each comes with its own lease, its own landlord and its own way of failing at the worst possible moment.
Rossi exists to make that straightforward. We explain what we find in plain English, give you a written price before any work, do the job cleanly and handle the paperwork, and we stand behind it.
- 01Listen first
How you live or work in a building shapes every recommendation we make.
- 02Diagnose before parts
Readings and inspection come first. You see what we see.
- 03Stand behind it
We stay available after the job, for questions, adjustments and the annual service.
