Home energy upgrades in the London.
London has the highest energy bills in the UK and the tightest housing stock — Victorian terraces, party-wall constraints, conservation-area density and tight loft space all change the retrofit calculus. Internal wall insulation, multifoil and rooftop solar are usually the highest-impact moves; cavity wall is rarely available. London has shown the fastest heat-pump growth of any English region over the last five years. OMEGA crews install across all 32 boroughs directly.
