Electric Storage Heater Replacement Faulty or inefficient storage heaters are now included in the Energy Companies Obligation scheme (ECO), and the value of the grant is up to 100%, dependent on circumstance. You'll probably find your property has storage heaters if you're not served by mains gas, or in flats and apartments where gas supplies are not recommended. If they're not working properly, or aren't keeping you as toasty warm as you'd like then there's a great possibility you're eligible for replacement modern units. Here at UK Energy Save Ltd we can check your eligibility and get them replaced quickly. Complete our application form, and we'll give you a call to discuss eligibility.
