Combi boilers prices vary hugely in price –
Normally from £500 to £2800 depending on brand, insurance/warranty, installation and, of course, the size/power.
Combi’s are the most popular type of boiler used in the UK,
mainly because they’re compact units that don’t require a cold-water tank or hot water storage cylinder to provide heating and hot water for homes.
Modern combi boilers also tend to be the most energy efficient as they deliver a fast supply of instant hot water whenever a tap is turned on.
As combi boilers have the ability to provide on-demand heating and hot water without needing any additional components, they are particularly ideal for flats and houses where space is restricted.
When it comes to choosing a combi boiler for your home, we always recommend you compare models and costs from some of the top rated and most reliable brands. Prices differ according to the manufacturer and the overall boiler quality, but there are plenty of combi boilers available to suit all budgets.
