Financing your combi boiler

Financing options for a combi boiler can significantly ease the upfront financial burden, making the investment more manageable. Different methods are available, from finance plans to government grants, each with unique benefits that suit varying financial situations.

  • Boiler finance plans: Many suppliers offer finance plans that allow you to spread the cost of the boiler and installation over a set period, often with low or 0% interest rates.
  • Home improvement loans: Banks or other lenders provide these loans specifically for home renovations, including boiler replacements. Interest rates and terms can vary.
  • Energy supplier schemes: Some energy companies offer financing or incentive schemes to help with the upfront costs of a new boiler, often as part of broader energy efficiency programs.

Government grants and incentives

Numerous government grants and incentives are available to help finance boiler installations, promoting energy efficiency and reducing carbon footprints.

  • Energy Company Obligation (ECO): This scheme requires large energy companies to provide grants for energy efficiency improvements, including boiler replacements, to eligible customers. Benefits often include significant financial assistance and reduced energy bills.
  • Boiler replacement allowance: Some local councils and government bodies offer allowances to assist with the costs of a new boiler, often aimed at low-income households. This can greatly reduce upfront expenses.
  • Green homes grant: While this scheme has closed, other similar environmental incentives may become available, providing funds for energy-saving home improvements, including eco-friendly boiler installations. Keep an eye on new initiatives.

These financing methods and government incentives can make getting a new, efficient combi boiler more affordable and help manage long-term home heating costs.
