Over the course of your heating system’s accreditation, it may be necessary to replace parts to keep it in good working order. You must notify us if:
- It’s not in good working order (or hasn’t been in good working order) and once it’s fixed;
- The MCS approved product is replaced; or
- The entire heating system is replaced
Replacements have to meet certain rules and may affect your payments. For more information, see Section 10 of the Essential guide for Applicants.
