Know Your Budget; Be Realistic and Informed

Before diving headfirst into boiler options, understanding your budget is crucial. Boiler prices can vary significantly depending on the brand, efficiency rating, size, and additional features. Here’s what to consider:


Boiler Types and Costs:

Boiler Type: While combi boilers may offer space-saving benefits, they are not necessarily the most expensive option. Regular and system boilers typically come with lower upfront costs but may require a separate hot water cylinder.

Combi boilers:

These can sometimes be the most expensive upfront due to their combined heating and hot water functionality. However, they eliminate the need for a separate hot water cylinder, saving space in smaller properties.

Regular boiler (conventional boilers and heat-only boilers):

These generally have a lower upfront cost compared to combi boilers. However, they require a separate hot water cylinder for storing heated water, which adds to the overall installation cost and space requirements.

System boilers:

The system boiler is a more complex boiler model than the conventional boiler. You can find them in any boiler brand but they will not fit into your current heating system if they are not compatible. It can be converted, though. These fall somewhere in the middle price range between combi and regular boilers. They offer improved hot water flow and pressure compared to regular boilers and don’t require a cold water storage tank (like some regular boilers). However, they still necessitate a separate hot water cylinder.

Efficiency Rating:

Higher-efficiency boilers (rated A or higher) might have a slightly steeper initial cost but translate to significant savings on your energy bills in the long run.

Brand – Boiler Manufacturers

Reputable brands like Worcester Bosch, Vaillant, Ideal Boilers, Baxi, and Glow Worm offer reliable options at various price points. They have multiple new boiler ranges available from combi boiler, system or heat-only.

Embrace the Power of Research: Compare Brands and Models

With boiler size and your budget in mind, delve into the world of boiler brands and models.

Here’s what to research:

Brand Reputation: Look for established brands with a history of producing reliable and energy-efficient, boilers. Online reviews and Which? reports can be valuable resources.

Boiler Features: Compare features like hot water output, controls, size, and warranty length. Consider your specific needs and choose between a rated boiler or a boiler that meets them efficiently.

Efficiency Ratings: A higher ErP (energy-related products) rating translates to lower energy bills.

Does a Pre-Purchase Plumbing survey check the condition of the boiler?

With MML Plumbing it does, as a gas-safe registered company this is our trade. Although Surveyors study building structures and not heating and appliances.

  • Structural Surveyors: Their expertise lies in evaluating the structural integrity of a building, including foundations, walls, roofs, etc. They may not have the specific training or equipment to diagnose boiler issues.
  • Gas Safe Registered Engineers: They hold the necessary qualifications to inspect and service gas appliances. They can assess the boiler’s efficiency, safety, and potential problems.
