Using this Guide:

Worcester Bosch manufacturer mid-range to premium combi boilers, so our comparison is centred around Vaillant, Baxi and Ideal combi models in this price range. Please see our Combi Boiler Prices guide for a comprehensive listing of entry level, economy, mid-range and premium combi boilers from eight manufacturers.

Across our advice pages we have divided combi boilers into four price groups (below). This Guide only uses the Mid Range and Premium categories as Worcester only manufacturer boilers in these categories.

 Entry level (cheapest)
 Economy (one-up from Entry level)
 Mid-Range (one down from Premium)
​ Premium (the most expensive)

We have then sub-divided each price group into four combi boiler sizes:

​The four sizes are governed by the heating output and hot water flow rates – very roughly - to show: Small, Medium, Large and Extra Large capacity boilers.
