Boiler Installation Across the Scottish Borders

Vaillant Advanced Installers based in Kelso, fitting gas, oil and LPG boilers from Berwickshire through to Tweeddale and Liddesdale. Most Borders installs are a like-for-like combi swap done in a day; a full system upgrade with a new flue, magnetic filter and smart controls usually runs to two or three days on site.

Most Borders boiler installations land between £2,200 and £4,500 depending on brand, controls and any system upgrades.

Why Borders homeowners pick us for boiler installation

  • Up to 12-year manufacturer warranty as Vaillant Advanced Installers — we register the warranty for you on commissioning day.
  • Oil and LPG covered too — essential for the rural Borders where mains gas thins out fast beyond the main towns.
  • Free survey and fixed written quote — never priced over the phone, never any commission-based sales visits.
  • Cold-climate detailing built in: 32mm condensate runs, weatherproof lagging on any external pipework, frost-protected siting.

What we'll do

  • Free survey and a fixed written quote — no high-pressure sales, no commission visits.
  • Up to 12-year Vaillant warranty registration handled for you on the day.
  • Magnetic system filter and full power-flush included on system upgrades.
  • Old boiler, flue and any redundant pipework removed and disposed of responsibly.
  • Smart heating controls (Vaillant vSMART or equivalent) fitted as standard.
