Coldstream sits right on the border, with a tight high street, a strong rural hinterland on both sides of the Tweed and a steady stream of cross-border work into north Northumberland. Many properties here are stone-built and sit outside the mains gas network, making oil servicing and LPG installs a real specialism for the area.
As Vaillant Advanced Installers we install gas, oil and LPG boilers across Coldstream 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 Coldstream 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 Coldstream (TD12) installation runs efficiently from day one rather than short-cycling through the first winter.
Travel from our Kelso base: 15 minutes via the A698.

Yes — most of our TD12 work is off-grid oil and LPG servicing, repairs and replacements. We carry common spares for Grant, Worcester Bosch, Warmflow and Vaillant on the van.
Yes — bespoke heating design for larger country properties is a regular part of what we do. We size systems and zone controls properly rather than fitting domestic kit at scale.
Most domestic installations fall between £2,200 and £4,500 depending on make, model, controls and any system upgrades. We give you a fixed written price after a free site visit — no surprises on the day.
Up to 12 years on Vaillant boilers as Advanced Installers; 7–10 years typical on Worcester Bosch, Ideal and Baxi. We register the warranty for you on the day of commissioning.
A like-for-like combi swap usually means one day with the heating off. A full system upgrade or a back-boiler-to-combi conversion runs two to three days. We'll always tell you up front what to expect.
