Local knowledge
Croydon housing & boilers
Croydon housing is dominated by Victorian terraces, 1930s semis and high-rise conversions in the centre. In Croydon's CR0 and CR2 postal districts, the housing stock presents specific considerations for a new boiler. Victorian terraces and 1930s semis in areas like Purley and Thornton Heath often involve flue routing challenges, while high-rise conversions in the centre frequently require leaseholder consent from the building freeholder before any installation work can proceed. For the many period properties here, the available space for a hot water cylinder or the local mains pressure can be key factors in choosing a suitable replacement boiler. This makes understanding the differences between combi, system and regular boilers an important first step for many households.
Knowing the local building stock matters: it tells us what to expect on flue routing, pipework and available space for a cylinder — before we arrive for the survey.
