Before and After Power Flush Checks
The difference a power flush makes should be shown, not just claimed. These are the before and after power flush checks we carry out, so you can see what changed rather than take it on trust.
In short
Before the flush we note the starting condition: water clarity, filter state and how the radiators respond. After the flush we check the same things again. The comparison is what tells you the clean worked. All power flushing work is carried out by a fully qualified Gas Safe registered engineer, and the checks can be noted on a completion record where appropriate.
What we check before the flush
- Water clarityA sample drawn from the system shows how dark and debris-laden the water is at the start.
- Filter conditionHow full the magnetic filter is, and how much sludge it holds.
- Radiator responseWhich radiators are slow, cold at the bottom or cold altogether, with thermal checks where appropriate.
- System notesThe system type, radiator count and anything already known to be faulty, so the flush is judged fairly.
What we check after the flush
- Water clarity againThe same check repeated, so the change is visible side by side.
- Filter and debrisWhat the flush pulled out, cleaned from the filter and noted.
- Radiator response againHeat response re-checked across the system, including the radiators that were slow before.
- Photo evidence where appropriateBefore-and-after images for your own records or a property file.
- Completion record where appropriateThe checks summarised in writing for landlords, agents and installers.

Checks show what changed; they do not guarantee an outcome. If a radiator stays cold after a proper flush, the cause is usually a valve, balancing or pipework issue rather than sludge, and the before-and-after comparison is exactly what makes that visible. Records of the checks may support your paperwork but do not themselves validate a boiler warranty.

Common questions
Are the before and after checks included?
Yes. Checking the system before and after is part of how Regent works, and the results can be noted on a completion record where appropriate.
Is the work carried out by a Gas Safe registered engineer?
Yes. All power flushing work is carried out by a fully qualified Gas Safe registered engineer.
Will I get the photos?
Photo evidence is provided where appropriate, and it is useful for your own records, a property file or your boiler installer.
What if a radiator is still cold afterwards?
Then the checks have done their job: they show the flush was done properly and point to a different cause, usually a valve, balancing or pipework issue, which we will explain.
