What I noticed
Worcester Bosch is the dominant brand in UK gas boiler installs, and their Compress 7000i AW brings that same distribution advantage to air-source heat pumps. Many Gas Safe engineers are now also MCS-certified, and a significant number have trained on Worcester Bosch heat pumps — which helps with availability and familiarity on site.
Who it suits
Homeowners who already have a Worcester Bosch boiler and want continuity of brand and service, or those whose heating engineer has specifically recommended this model based on their training.
Watch for
Efficiency figures are solid but not market-leading. As with most established gas-brand entrants to the heat pump market, brand recognition is the main premium over European-native heat pump brands.
