Below, we’ve covered current combi boiler prices for all units from 24kw-42kw. At the end of the article we’ve explained the combi boiler replacement quotes you should be expecting to receive.
Essentially, it boilers down to this…
If your looking for competitive combi boiler prices, we’d look no further than BOXT. They’re part owned by Bosch, who in turn, own Worcester Bosch. And, that means the installation prices for combi boilers they offer are up there with the most competitive.
Smaller houses and apartments will usually use a boiler in the 24kw-27kw range. That assumes that you only have 1 bathroom, and no more than 10 radiators.
If you have more than 1 bathroom, more than 10 radiators, or have high demand for hot water (shower and taps on at the same time), it’s likely you’ll need something different.
A new boiler in the low kw range is always going to be the cheapest. We’ve detailed a few popular combi boiler prices below.
|Baxi Duo-Tec 24 (ErP)||24kw||£725|
|Vaillant ecoTec 24||24kw||£890|
|Worcester Greenstar 25I||25kw||£920|
|Ideal Logic Plus 24||24kw||£770|
There’s a lot that goes into combi boiler prices than just the purchase of the boiler. You’ll need a flue, a magnetic system filter, extensions and there’s a chance the gas engineer will need to re-route or move pipe-work.
Expect a typical installation including the cost of the new boiler, materials and labour to be in the £2,000 range, for small properties.
That said, Bosch have recently invested in an online boiler installation website, BOXT. Naturally, BOXT are getting great deals on Worcester Bosch boilers, you can get a fixed price online in around 90 seconds. Here’s the quote we just got:
If you have a property with 2-4 bedrooms, 1-2 bathrooms and up to 15 radiators, you’ll be looking at a larger boiler than 24kw-27kw. A more suitable size for your property is going to be in the 28-34kw range, and there’s plenty of choice.
Combi boiler prices in the 28kw-34kw range can be 10-30% more than the 24-27kw equivalents.
|Baxi Duo-Tec 28 (ErP)||28kw||£850|
|Vaillant ecoTec 28||28kw||£900|
|Worcester Greenstar 30I||30kw||£1,050|
|Ideal Logic Plus 30||30kw||£850|
|Worcester Greenstar Classic 34CDI||34kw||£1,350|
The price in the 28kw-34kw will also need to include items like flue, a magnetic system filter and extentsions.
Expect a typical installation including the cost of the new boiler, materials and labour to be in the £2,200-£2,450 range.
Using the clickable online tool on BOXT (part owned by Bosch), here’s the quote we just got for a 30kw boiler (you can get yours on-screen using their online form here):
The price for your combi boiler will vary depending on the answers you provide on their clickable multiple choice survey.
We’re getting to the high end of what a combi boiler can really do. Any bigger than a 4-5-bedroom property with 2 bathrooms and up to 20 radiators, and you’ll need something else, perhaps a system boiler (consult an engineer first).
Combi boiler prices in the 35kw-42kw range tend to be incredibly expensive, almost double that of the 24kw combi in some cases.
|Baxi Duo-Tec Platinum 40 (ErP)||40kw||£1,200|
|Worcester Greenstar 38CDI||38kw||£1,550|
|Ideal Logic Plus 35||35kw||£980|
|Ideal Vogue 35||35kw||£1,190|
|Worcester Greenstar Classic 42CDI||42kw||£1,750|
The bigger the boiler, the higher the prices are going to be. For a top boiler at a reasonable price, we’d suggest spending 90 seconds and getting your fixed price on-screen via BOXT. Typically, they’re going to be on-par if not cheaper than local installers.
The overall cost of combi boiler replacements factors in a range of different things such as:
To save the complications, after account for the combi boiler price (boiler only), I’d expect to add on the following costs for a basic new boiler swap.
Price Of Materials And Labour
As we mentioned above, some of the cheapest combi boiler prices available come via BOXT. Due to their connection to Bosch and therefore Worcester Bosch, their prices are extremely competitive.
