Brand Heritage and Company Background
While both Baxi and Potterton now operate under the same corporate umbrella, they've taken very different paths to get there.
Baxi's story begins in 1866 when Richard Baxendale started the company in Preston, Lancashire. You might say they were heating pioneers – they launched their first branded product in 1935 and later gave us the famous Bermuda back boiler in 1966 (if you're of a certain age, your parents probably had one of these).
Potterton, meanwhile, has built its reputation as a premium brand in the UK heating market. When these two heating giants merged in 2000, they became part of what would eventually become the BDR Thermea group – a global powerhouse with over 6,400 employees.
Today, both brands share manufacturing facilities and technology, but maintain their distinct product lines. Think of them as siblings – related but each with their own personality and strengths. Our website features an extensive collection of Baxi boiler articles covering everything from technical specifications to maintenance tips.
Energy Performance and Efficiency Ratings
When comparing energy efficiency between Baxi and Potterton boilers, you'll find they're both strong performers in the A-rated category.
Baxi edges slightly ahead with efficiency ratings of 92-93%, while Potterton models range from 89-93%.
If you're looking for top-tier efficiency, the Baxi Megaflow stands out with an impressive 98% rating, while the Baxi 200 Combi achieves 94%.
These numbers translate directly to your energy bills – the higher the efficiency, the lower your gas consumption.
To put this into perspective, Baxi's range shows a clear efficiency progression: their 300 Combi uses just 9,000 kWh annually, compared to 12,000 kWh for the 100 Combi.
That's the kind of difference you'll notice when your gas bill arrives!
Both brands meet modern efficiency standards with their A-rated ErP certifications, though Baxi's newer models tend to perform slightly better in real-world testing.

Product Range and Model Options
Both Baxi and Potterton offer extensive boiler ranges to match your home's specific heating needs.
You'll find a thorough selection of combi, system, and heat-only models across various power outputs to suit different property sizes.
Looking at the options, you're spoiled for choice with both brands.
Here's what stands out in their ranges:
- Baxi's 800 Combi 2 series offers four power outputs from 24kW to 36kW
- Potterton's Promax Ultra Combi matches this with outputs from 24kW to 40kW
- Both brands provide compact options for smaller homes, starting at 12-13kW
- You'll find similar mid-range offerings around the 24-28kW mark
- System boiler options extend up to 32kW for larger properties
Whether you're heating a cosy apartment or a sprawling family home, both manufacturers have got you covered.
The parallel nature of their ranges makes sense, as they're actually sister companies under the same corporate umbrella.
Warranty Coverage and After-Sales Support
Since warranty coverage can make or break your boiler investment, you'll want to pay close attention to what each manufacturer offers.
Baxi takes the lead in warranty duration, offering up to 10 years on their 800 range, while Potterton's Titanium range maxes out at 7 years.
Don't forget though – you'll need to register either brand within 30 days of installation, or you'll be stuck with just a 1-year warranty!
Both manufacturers cover parts and labour for manufacturing defects, but they won't help if you've accidentally knocked the boiler with your ladder (we've all been there).
You'll also need to keep up with annual servicing to maintain your warranty.
When it comes to after-sales support, Baxi relies on their in-house technicians, while Potterton works through approved installers.
Both offer helplines, though customer service experiences can be hit-or-miss with either brand.
Customer Reviews and Reliability Ratings

Cost Analysis and Value for Money
When it comes to getting the best bang for your buck, the price differences between Baxi and Potterton boilers tell an interesting story.
Baxi's combi boilers range from £730 to £1,300, while Potterton's stretch from £680 to £2,500. If you're thinking that's quite a gap, you're right! The installation costs are neck-and-neck though, running £800 to £1,300 for both brands.

Efficiency-wise, Baxi edges ahead again. Their boilers achieve up to 94% efficiency, compared to Potterton's 89%. That means more of your hard-earned money stays in your pocket rather than escaping through the flue pipe.
