Frequently Asked Questions
Can my back boiler be repaired?
It depends on the fault and parts availability. Due to the age of these systems and scarcity of parts, replacement is often more cost-effective than repair.
What happens to my fireplace during conversion?
The fireplace can be capped and made safe, or converted to a decorative feature. We can also install a modern gas fire in the same location if desired.
How much does conversion cost?
Costs vary depending on the new system chosen and any additional work required. We provide detailed quotes including safe removal and new installation.
