Two roof slopes, a chimney, party walls on both sides. Victorian terraces are the most-installed UK property type — and the one with the most fiddly trade-offs.
A Victorian terrace typically takes a 3.0–4.0 kWp install, fitted price £6,200–£8,400 in 2026. Slate roofs add £400–£700 over concrete-tile equivalents because of trickier hook/flashing work. Conservation areas need a planning check; listed buildings nearly always need full listed-building consent.
