Boiler Installation in Gillingham
Gillingham is the largest town in Medway by population, stretching from the former military areas around Brompton Barracks in the west to the suburban estates of Parkwood and Twydall in the east. This breadth means the town encompasses an exceptionally varied housing stock.
Why Choose Advance Medway for Boiler Installation in Gillingham
Gillingham covers a large area, and finding a boiler installer who genuinely understands the different neighbourhoods and property types matters more than most homeowners realise. A boiler that suits a compact terrace near Gillingham station is not the same boiler that works best in a four-bedroom detached house in Parkwood. We live and work in Medway, so we know these areas and the properties in them.
Our engineers are Gas Safe registered, which is the legal minimum for anyone working on gas appliances. But we go further than minimum compliance. Every installation follows the boiler manufacturer's specific guidelines, which means your warranty is valid from the moment we finish the job. We have seen too many installations by other firms where corners have been cut during fitting, leaving the homeowner with a voided warranty when something goes wrong two years later.
We provide honest advice about which boiler is right for your home. If a £1,900 combi boiler will do the job properly, we will tell you that rather than pushing a more expensive option you do not need. Similarly, if your home genuinely requires a system boiler to meet its hot water demands, we will explain why and show you the options.
Gillingham has a significant rental market, and we work with landlords across the ME7 and ME8 postcodes who need reliable boiler installations that meet current regulations and keep tenants safe and warm.
Boiler Installation for Gillingham Properties
Gillingham's housing ranges across more than a century of construction, and each era brings different heating considerations.
Victorian and Edwardian terraces (Gillingham town centre, Canterbury Street, Nelson Road): These narrow, two- and three-bedroom houses often have limited wall space for a boiler and may still have back boilers or old floor-standing units. A compact wall-mounted combi boiler is usually the best replacement option, providing heating and instant hot water while freeing up floor space. In these properties, we often position the boiler in the kitchen, utilising the existing gas run to minimise disruption.
Post-war semi-detached houses (Twydall, Parkwood, Beechings Way): Three-bedroom semis from the 1950s through to the 1970s are the most common property type in eastern Gillingham. These homes typically have conventional heating systems with a hot water cylinder in the airing cupboard. For families of three or four, a 30kW combi boiler handles both heating and hot water effectively. Larger families or homes with multiple bathrooms may benefit from a system boiler with an unvented cylinder.
1970s-1990s estates (Hempstead, Wigmore borders): Properties built during this period often have their original boilers nearing the end of a useful life. These are typically straightforward like-for-like replacements, with the existing pipework in good enough condition to retain.
