Potterton Boilers – Review, Prices & How To Get The Best Deal

Good

• ErP class A, with 93% seasonal space heating efficiency (ηs) across all five Titanium Heat models (12–30kW), above the 92% Boiler Plus minimum (baxi.co.uk).
• The Titanium Combi 24kW is cheap to have fitted: Boiler Guide puts the typical total at £1,650–£2,150 (boilerguide.co.uk). That is below the £2,500–£4,000 UK like-for-like combi range on our boiler cost page (Checkatrade).
• Owner support comes from Baxi, which says it has "over two hundred and fifty engineers", vans stocked with genuine parts, and phone lines open Mon–Fri 8am–6pm and Saturdays/Bank Holidays 8:30am–2pm (baxi.co.uk).
• 79% of Potterton boiler owners in Which?'s May/June 2025 survey said they were happy with their boiler (which.co.uk).

Not so good

• Potterton's own Trustpilot profile scores 1.9 ("Poor") from just 12 reviews. It is unclaimed and has had 0 reviews in the last 12 months (uk.trustpilot.com).
• Which? gave Potterton just three stars for customer score in its 2025 survey. Satisfaction (79%) is "three percentage points below the average" (which.co.uk).
• Baxi's homeowner site lists only one Potterton domestic boiler, the Titanium Heat (heat-only). potterton.co.uk now serves Baxi's homepage, whose brand portfolio names "Remeha, Potterton Commercial, Andrews water heaters, and Heatrae Sadia" but not Potterton residential (baxi.co.uk, potterton.co.uk).
• The Potterton Titanium Combi 24kW is shown as "Out of stock" for both delivery and collection at JT Atkinson (jtatkinson.co.uk).
• The Titanium Heat warranty depends on installation steps: the system "must be thoroughly flushed and treated after installation with inhibitor… Failure to do so will invalidate the appliance warranty", and the Benchmark Commissioning Checklist "is a condition of the warranty" (Potterton Titanium Heat Installation & Service Manual) (edge.sitecorecloud.io)
• Its older SEDBUK/SAP 2009 annual efficiency is 89.1–89.2%, below the 93% ErP figure (edge.sitecorecloud.io).

Gas Boilers

The gas boilers from Potterton are made in the UK, and they are tested strictly before they are released from their factories.

Their gas boilers are also easy to install and maintain.

Combination Boilers

Combination boilers are the most popular type of boiler for homes, because they don’t take up a lot of room and they don’t need a cold water tank and hot water cylinder.

The Potterton system boilers come in a range of energy outputs, with 12kW models for one -bedroom flats up to 24kW boilers suited for a two- or three-bedroom home with one bathroom.
