What shapes the job more is the neighbourhood itself — riverfront offices and legal quarter streets running up to Fleet Street — which is why a EC4 quote is not a City of London average.
On access, embankment red route with no stopping; access is via the side lanes with a permit — one reason two to three operatives as standard, with a specialist F-gas engineer booked in for any unit holding refrigerant-charged equipment.
