Replacing your gas back boiler will not be the easiest of tasks. Getting behind your fireplace to remove and replace a back boiler is often going to be quite destructive work. There may be some damage to your home. In most cases, your fire mantle and at least some of the flooring will need to be removed.

When replacing your gas back boiler the whole back boiler will need to be removed. After new boiler installation, combi or conventional, you may need new pipework.

Decommissioning a Back Boiler

By decommissioning a back boiler, it won’t actually be removed from behind the fireplace. Decommission effectively means it will disconnect from its source of power/energy. It will remain behind your fireplace gathering dust out of use.

To decommission your old back boiler, engineers will need to get behind your fireplace, which means you will likely have some damage to your fireplace and carpet. Prepare to make repairs afterwards.

However, decommissioning your back boiler instead of removing and replacing it, will save you money. Savings will depend on who is doing the work and what exactly needs doing. On average, you can expect a boiler decommissioning to cost around £3000. We have payment plans available when replacing back boilers, don’t worry.

Before making a bold decision, decommissioning might not always be an option. Always speak to one of our Gas Safe heating engineer who will decide whether it can be safely done.
