Company Heritage and Market Position
While both Alpha and Potterton have carved out their place in the UK boiler market, their journeys couldn't be more different.
Potterton's story starts way back in 1850 (they're practically old enough to have heated dinosaur caves!), and they've even warmed up Buckingham Palace with their boilers in the early 1900s.
Alpha, on the other hand, is the newer kid on the block with just over 50 years of experience. But don't let their youth fool you – they're part of the Immergas group, which pumps out a whopping 7 million boilers annually across 30 countries.
When it comes to market position, Alpha's been climbing the ranks as a budget-friendly option, currently sitting pretty at #3 in Heatable's top UK boiler brands.
Potterton holds the #8 spot and has built its reputation on reliability, especially in the social housing sector.

Product Range Comparison
When it comes to product variety, both Alpha and Potterton have got you covered with impressive lineups that'll suit most heating needs.
Alpha's range starts with their entry-level E-Tec series and moves up to the premium Evoke models with fancy touchscreen controls. You'll find outputs from 24kW to 38kW in their combi range – perfect for most UK homes.
If you're running a business, their ARES Tec commercial units pack a serious punch at up to 900kW.
Potterton matches up nicely with their Assure and Promax ranges for residential use, offering outputs from 24kW to 40kW for combis.
Their Titanium series comes with a reassuring 10-year warranty, while the Sirius Three commercial range tops out at 150kW.
Both brands offer LPG options and various boiler types (combi, system, and regular/heat-only), so you're not likely to be stuck for choice with either manufacturer.

Energy Performance and Efficiency
Since you're looking to trim those energy bills, efficiency ratings should be at the top of your checklist when comparing boiler brands.
Both Alpha and Potterton deliver impressive efficiency numbers. Alpha's E-Tec 28 NX model reaches up to 94% efficiency, while Potterton's Assure range maintains a solid 93% across their models.
You'll find both brands comfortably sitting in the coveted A-rating category.
What does this mean for your wallet? Well, compared to older non-condensing boilers (which typically run at 70-79% efficiency), you could save anywhere from £45 to £300 annually on your energy bills with these modern condensing units.
The seasonal efficiency is where things get interesting. Both brands use SEDBUK ratings to measure how well they perform throughout the year – because let's face it, your boiler needs to work just as hard during those chilly winter mornings as it does in milder months.

Warranty Terms and After-Sales Support
Because a boiler's warranty can make or break your peace of mind, let's explore what Alpha and Potterton offer regarding protection for your investment.
Alpha's warranty terms are clearly defined, with their E-Tec Plus combi boiler leading the pack at 10 years, while other models offer 7-year coverage.
When it comes to after-sales support, both brands have strong offerings, but there are some key differences you'll want to take into account:
- Alpha requires registration within 30 days and won't accept third-party repair invoices, while Potterton's HeatTeam provides more flexibility.
- Both brands offer 24/7 technical support, but Potterton's HeatTeam covers multiple brands under the Baxi umbrella.
- You'll need annual servicing by Gas Safe registered engineers to maintain either warranty – there's no getting around this one!
Price Analysis and Value for Money
The price tag on your new boiler matters just as much as its warranty coverage. When comparing Alpha and Potterton, you'll find both brands offer competitive options that won't break the bank.
| Boiler Type | Alpha Price Range | Potterton Price Range |
|---|---|---|
| Combi | £695 – £2,000 | £696 – £1,310 |
| System | £920 – £2,215 | £589 – £1,250 |
| Heat-only | From £599 | From £669 |
If you're shopping on a tight budget, Potterton's entry-level models are slightly more wallet-friendly. Their Titanium range, priced between £699 and £899, offers particularly good value. However, if you're looking for premium features, Alpha's high-end models pack more bells and whistles, though they'll cost you more.
Both manufacturers help you save on running costs with A-rated efficiency and smart control compatibility. You'll also appreciate their space-saving designs and LPG compatibility options, which can make installation more cost-effective. To ensure you get the best possible price, compare quotes from Gas Safe registered installers in your area.

Let's break down what customers are saying about both brands:
- Alpha's getting praise for quick engineer response times and effective problem-solving, though some owners report needing regular maintenance.
