The boilers we would actually specify in 2026, with an honest reason for each.
- Greenstar 4000 30kW Combi
£2,400 to £2,900 installed. Worcester Bosch's accessibly-priced combi for a typical UK 3-bed.
- ecoTEC plus 832 Combi
£2,600 to £3,200 installed. Vaillant's mid-range combi pairs cleanly with weather compensation and is widely fitted by installers who also work on the aroTHERM heat-pump range.
- Logic Max C30 Combi
£1,900 to £2,400 installed. Built in Hull, sensibly priced and supported by a deep British installer base.
- Vitodens 100-W 30kW Combi
£2,500 to £3,100 installed. Viessmann's mass-market combi brings the brand's quiet condensing operation down to a price tier where it competes with Worcester and Vaillant.
- 800 Combi 2 30kW
£2,000 to £2,500 installed. Baxi's mid-market combi is the boiler your local gas engineer is most likely to have on the van when a Tuesday breakdown becomes a Wednesday install.
