New Boiler Installation in London

New boiler installation in London: what the price includes

• 01
  Proper sizing survey

  Heat loss, hot water demand and mains flow measured, oversized boilers short-cycle and die young.

• 02
  Major brands, real warranties

  Fitted to manufacturer spec so the 7–12 year warranties actually hold, and registered before we leave.

• 03
  System cleanse included

  Flush and inhibitor with a magnetic filter fitted, the warranty small print demands it and so do we.

• 04
  Old boiler handled

  Decommissioned, removed, and the paperwork (Building Regs notification, Benchmark) done properly.

Local conditions we work around

A new boiler in London is only as good as what it is connected to. Hard water at 280 to 320 ppm will scale a brand-new heat exchanger if the system is not flushed and treated first, which is why a chemical or power flush and a scale reducer on the mains are part of the specification here rather than an upsell. In flats, flue routing and termination into lightwells and shared elevations, plus freeholder consent, are settled at survey before a date is offered.
