Just below, we have a list of options and estimates relating to how much a central heating power flush should cost assuming you come through our company.

What is the minimal to having my central heating system cleaned and how much will it cost?


The minimal amount to clean your central heating system water as to a temperary measures would be £299 excluding vat.

What you get for this is some cleaning fluid put in your central heating system and the boiler running for half an hour and then the central heating system being drained.

This will get rid of most of your dirty instant central heating water but not all because we're only estimating a quick solution as a temporary basis until you have a proper job done.

If you're having a new central heating system fitted in a month or two, we would recommend this option and in some cases, this could be an ok solution for the next 12 months.

How much does it cost to get a central heating power flush done


Just below are the set costs for getting a central heating power flush subject to any additional VAT on top at 20% if applicable. Please note that VAT is subject to additional VAT.

These costs can be broken up into a call-out fee and a labour costs which is further explained below:
