What Determines New Boiler Cost in Slough?
Several factors shape the final price of a new boiler installation in Slough. Location-specific elements like access to the property, existing pipework condition, and local labour rates all play a role. Slough’s mix of Victorian terraces, 1930s semis, and newer flats means installations vary from straightforward swaps to jobs requiring extra pipework or power flushing.

- Brand and model (premium vs budget)
- Property size and number of bathrooms
- Extras like smart thermostats, filters, or flue adjustments
- Whether power flushing or minor pipe alterations are needed
Why Replace Your Boiler in 2026?
If your boiler is over 10–15 years old, it’s likely only 60–70% efficient. Modern A-rated boilers reach 90%+ efficiency, potentially saving £300–£600 per year on bills for a typical Slough household. New models are quieter, more reliable, and often include smart controls for app-based operation – ideal for commuters in this busy town.
Plus, upgrading now avoids expensive winter breakdowns and may boost your home’s EPC rating and resale value.
