Local knowledge
Lewisham housing & boilers
Lewisham housing is dominated by Victorian and Edwardian terraces with period conversions. In Lewisham's Victorian and Edwardian terraces and period conversions, a boiler replacement often involves specific practical considerations. For leasehold flats in areas like Forest Hill or Blackheath, securing freeholder consent is a necessary first step. Flue routing can also require careful planning to meet conservation area guidelines, particularly for properties in postal districts like SE23 or SE13. For larger period homes in Catford or Deptford with multiple bathrooms, a system boiler with a cylinder might be a suitable option to ensure good hot water flow. Understanding the differences between combi, system, and regular boilers can help determine the best replacement for your property's layout and needs.
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.
