How Much Does a New Boiler Cost in Kent? (2026 Honest Guide)
Wondering what a new boiler costs in Kent in 2026? HOCU breaks down honest price ranges for supply, installation, and what affects your final quote across ME and TN postcodes.
What Affects the Cost of a New Boiler Installation?
No two installations are identical. The final price depends on several factors that any honest installer will walk you through upfront:
- Boiler type - combi, system, or regular each carry different unit and installation costs
- Boiler brand and output - premium brands like Worcester Bosch sit higher on price but carry longer warranties and better efficiency ratings
- Current system setup - a straight like-for-like swap costs less than changing boiler type or relocating the unit
- Additional work - new pipework, flue extensions, system flushes, or control upgrades all affect the final figure
- Property size - larger Kent homes with more radiators require higher output boilers
Realistic Price Ranges in Kent for 2026
These are honest, installed figures, supply and labour combined, based on typical jobs across the ME and TN postcode areas:
- Combi boiler replacement - £2,700 to £4,500 for most standard Kent homes
- System boiler installation - £3,200 to £5,500 depending on cylinder and system requirements
- Regular boiler replacement - £3,500 to £6,000 including associated tank and cylinder work
