BG – You need your central heating system Powerflushing, mate.

Me – and that’ll be how much?

BG – *sucks air through teeth* Ooh, about £700.

Me – Thank you, don’t bother.

Trusted local plumber – *studies system* Ah, call it £300.

BG? Set of thieving **@%* 👿

Standard BG pricing tactic, i.e. approximately double the market rate.

Ive just put some Fernox DS-40 Descaler and Cleanser in the system along with a magnetic filter on the return line to the boiler.

Will run the system for a week or two, then drain, clean the filter and refill. All in appx £90, did everything else myself

BG,And you also need a air vent into the attic loft space, as you have double glazing, and no trickle vents, you may well suffocate otherwise.

Customer, but ive lived here for 10 years and no problems, so how much.

BG, youre looking at £150 pounds to fit one and test the draught, issue certificate etc.

Another customer,

BG, have serviced your system and we recomennd a magnaclean be fitted, like a big magnet that sucks the iron fillings out of your system.

Customer, but doesnt a magnet magnetise iron particles, and a vacumn, sucks iron filings.

BG,we have a special offer on this week.Doesnt answer question and tries to flog a magnaclean type thing.

BG = bloody greedy.
