Save Energy with a New Boiler

Boilers that are over 10-15 years old perform much less efficiently than their modern equivalents. A typical 15 year old boiler can waste as much as 40% of the energy it produces, meaning it’s only 60% efficient, this is equivalent to a G rating. The older the boiler, the less energy efficient it will be.

We work with some of the most trusted and reliable brands in the industry, Worcester Bosch, Glow Worm, Vaillant and others, so we can offer a range of A-rated energy efficient boilers for you to choose from. New boilers are designed to operate at 90% efficiency, or more.

Ways to Pay for your New Boiler Installation

If you choose to pay with finance, you’ll need to understand the three different options available to you:
  1. Spread the cost over 12 months at 0%
  2. Spread the cost over 5 or 10 years with a 13.9% APR representative
  3. Spread the cost over 15 years with a 12.9% APR representative
Our lender offers two types of finance:
  1. Interest Free Credit means that you can spread the cost of your installation over a set period of time without incurring any interest on it. For instance, if you buy a boiler for £2,500 the total amount you’ll pay over 12 months will be £2,500.
  2. Interest Bearing Credit is slightly different in that you’ll pay the lender interest on the money you borrow at the rate they set, over the period you’ve chosen.
