"New boiler installation"

"New boiler installation 3rd floor of block of flats E18. ASAP as cheaply as possible. The existing boiler was installed without scaffolding. The plumber reached out of the window to do it. Now I'm being quoted £600 extra for scaffolding. Can you beat my existing price of £2560?"
