Replacing your boiler with Alpha
Alpha Heating Innovation is part of the Italian Immergas Group. Its combis are compact, use stainless steel heat exchangers and are often chosen as a well-priced alternative to the biggest names.
We fit Alpha’s E-Tec Plus and Evoke combis as like-for-like replacements and as conversions from tank-fed systems. Alpha also makes system and heat-only boilers for homes that need stored hot water.
The online quote shows the Alpha models that suit your home, with one fixed price for the job.
Most of the Alpha boilers we fit are combis, with system and heat-only models for homes that keep a cylinder.
| Model | Type | Best for |
|---|---|---|
| E-Tec Plus | Combi | Most homes; available in several outputs |
| Evoke | Combi | Compact combi for everyday swaps |
| Alpha system boilers | System | Homes with an unvented or vented cylinder |
| Alpha heat-only boilers | Heat-only (regular) | Homes keeping loft tanks and a cylinder |
Outputs and availability depend on your home, so your online quote only shows the Alpha models that suit it.
Alpha installation prices depend on the model, the output and the work your home needs. Across all brands, like-for-like combi swaps start from £1,759 fitted, and Alpha combis are typically a cost-effective choice for a straight swap.
Every quote is fixed, so nothing is added after the survey. You can also spread the cost: as an example, a £1,799 boiler over 10 years at 9.9% APR works out at £23.26 a month, subject to status.
Alpha combis are a cost-effective way to replace an older combi without dropping to a basic boiler.
The E-Tec Plus is compact, so it suits kitchen cupboards and smaller utility spaces.
With an annual service, a modern Alpha boiler should give years of reliable heating.
