This company charges over the odds for all elements of their quote. They charge £1,200 per day for labour. They charged me £1,800 for just under 8 hours work. How does that equate to 1.5 days? They charge £500 for additional 5 years extended warranty when the boiler manufacturer already provides 7-year free warranty if boiler installation is done by one of their approved installers; and PlumbingForce engineers are approved by this supplier. So effectively, I paid £500 extra for an additional 3-year warranty. The boiler unit with flue and additional kit costs less than £1,700 including vat. When you factor in supplier discount to PlumbingForce, its much less than that. PlumbingForce refuse to provide a copy of the original invoice from the boiler supplier for my records. They charged me £4,080 to install my boiler when several quotes like for like with exact same qualifications, certifications and same 10-year warranty came to £2,000. The gas engineer did not plug a leak in the filter at the end of day 1 leaving our hallway carpet wet. Had we not noticed, it would have been a disaster. He also did not ask for a vacuum to clean up the mess in the hallway. Very unprofessional. Finally, the current operations manager Michelle is very rude. She was very rude and curt on the phone. She does not respond to emails and when she does, she deliberately, sometimes, replies in CAPS, to shout back. She has at the time of typing failed to answer all my questions. There is no point sending emails to their enquiries email . She is one of the people responding to emails received, expect nothing short of extremely poor customer service. If you need a gas combi boiler installed with a 10-year warranty for a 3-bedroom house, it should cost you no more than £2,000. Shop around online, get a few quotes, speak to the boiler manufacturer/ supplier about the warranties available. Remember, a gas engineer hourly rate is about £60 per hour, even in London, so a day rate should not be more than £480 (£576 if they are vat registered). A boiler should not take more than 8 hours for installation by one engineer. Do not make the mistake I made, do not pay double the amount required. Get your quotes in and Do NOT USE PlumbingForce Ltd.
