Baxi Core Services

Heat-only Boilers

If you have a hot water storage cylinder as well as a cold water tank in your loft, you might benefit from heat only or regular boilers.

Thanks to the full range of energy output available, there will be a model for every type of home.

✔ 400 heat

✔ 600 heat

✔ 800 heat

System Boilers

System boilers are better suited for homes that have more than one bathroom and might need more hot water than what a combination boiler can provide.

These types of boilers usually pump hot water into your radiators and hot water storage tank, which might be built into the system to make installation easier.

• ✔ 600 System 2
• ✔ 800 System 2
• ✔ Megaflo Compact System

Combination Boilers

Combination boilers are usually the most popular types of boilers that you can find in a traditional home. They provide heating for both your water and central heating systems.

They also don’t require a hot water tank or cold water storage, making them more space-efficient and cost-effective.

✔ Duo-tec Compact

• ✔ Baxi Platinum Compact
• ✔ 200 Combi 2
• ✔ 400 Combi 2
• ✔ 600 Combi 2
• ✔ 800 Combi 2

Service

Baxi offers an annual boiler service, which will traditionally include a safety check, inspection of each part to see if your boiler is leaking or corroding, and a benchmark record. This ensures that your boiler is working to its full efficiency and remains safe.

Boiler care plans start at £14 per month for basic services and can reach £26.37/month for premium coverage.

Repairs

There are two main ways that you can get your boiler fixed. You could choose to book a one-off repair for your boiler, including call-out fee, parts replacement, labour, and VAT.

The parts will usually be guaranteed for around 12 months, and your labour will be covered for approximately 90 days.

The second option is to purchase repair and care for 12 months at a time, which will allow you to claim repairs of up to £1,500 over that year. If your boiler is deemed irreparable, you can have it replaced to a value of up to £750.

Baxi Reviews

On Trustpilot, Baxi has a 4.6/5 rating with over 56,000 reviews. About 80% are in the 5-star category and only 8% are in the 1-star group.

The brand’s knowledgeable engineers were highly praised in reviews, but some customers were unimpressed with the repair service.

While online reviews aren’t always accurate, they should still be considered when deciding on boiler manufacturers to contact.

Positive Baxi Review

Patricia Ann Lock on Trustpilot: “First class service very good customer care.”

Negative Baxi Review

Paul Bleasdale on Trustpilot: “For the third time, the promised call from a manager to discuss my concerns about their extremely poor service has not happened!”
