What Does Boiler Replacement Involve in Slough?
Boiler replacement means removing your old unit and installing a new, more efficient one. Most Slough homes opt for combi boilers for their compact design and instant hot water, but system or conventional types suit properties with higher demands or existing tanks.
Common Boiler Types for Replacement
- Combi boilers: Ideal for small to medium homes – no need for a hot water cylinder.
- System boilers: Better for larger households with multiple bathrooms.
- Conventional boilers: Suited to older Slough properties with loft tanks.
Why Replace Your Boiler in 2026?
Older boilers (10+ years) are inefficient, often below 70% efficiency, wasting gas and money. A new replacement delivers 90%+ efficiency, potentially saving £400–£650 annually on bills. It also reduces breakdowns, improves safety, and boosts your home's EPC rating – valuable in Slough's competitive property market.
Environmental and Practical Benefits
Modern condensing boilers cut carbon emissions and qualify for potential future incentives. Many include smart controls for app-based management.
