Powerflush Quote Template (UK): What to Include and an Example

Customers rarely know what a powerflush is or why it costs what it does. A quote that explains the symptoms, the process and the result turns a "how much?!" into a yes.

What a powerflush quote should include

  • Why it's needed (cold spots, noisy boiler, sludge)
  • Number of radiators
  • Chemicals and inhibitor
  • Filter fitting to keep it clean
  • What result to expect, without promising miracles

Common mistakes

Not explaining the why

Two lines on symptoms and benefits do more selling than a lower price.

Promising it fixes everything

If radiators are corroded through, a flush won't save them. Say the quote covers cleaning, not failed components.

Questions

How long does a powerflush take?

+

Most domestic systems take a day. Put your estimate on the quote.

Should I fit a filter with a powerflush?

+

Many engineers recommend one to keep the system clean afterwards. Quote it as a separate line so the customer can choose.

Is a powerflush needed for a new boiler?

+

Many manufacturers require the system to be cleaned for the warranty. Check the manufacturer's instructions and mention it.
