Boiler Installation in Kelso

Kelso is our home town and the base of every van we run. The mix of Georgian townhouses around The Square, modern estates off Inch Road and farms out toward Sprouston means we see almost every kind of heating system in one postcode — gas combis, oil boilers, LPG installs and a growing number of heat pump retrofits.

As Vaillant Advanced Installers we install gas, oil and LPG boilers across Kelso with manufacturer-backed warranties of up to 12 years. A like-for-like swap is usually a single-day job; a full system upgrade — new flue route, magnetic filter, smart controls, system flush and a fresh expansion vessel — typically runs to two or three days on site. We always quote in writing after a proper survey, never over the phone, and we never use commission-based salespeople in your home.

In Kelso we see a real mix of system types — older open-vent setups in the period stock, system boilers in mid-century housing and combis in newer builds. We size every replacement against actual hot-water demand and real radiator output, not a ballpark figure, so the new Kelso (TD5) installation runs efficiently from day one rather than short-cycling through the first winter.

Travel from our Kelso base: 0 minutes — we're based here.

Local considerations in Kelso

  • Many properties around The Square and Bowmont Street are stone-built with limited loft space — flueing and condensate routing need careful planning.
  • Outlying farms and steadings (Sprouston, Stichill, Smailholm) are off the gas grid and rely on oil or LPG, which we install and maintain regularly.
  • Newer estates such as Pinnaclehill and Inch Road typically have system or combi gas boilers — straightforward swaps with same-day completion.
  • Hard water in parts of TD5 means scale management and filter housings are worth specifying on new installs.

What we'll do for you

  • 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.
