Duns is the natural service town for Berwickshire — a working market town surrounded by big agricultural country. The mix of Victorian stone houses around the Square, post-war estates off Castle Street and a wide rural patch reaching toward Polwarth and Greenlaw makes for a healthy spread of gas, oil and LPG work.
As Vaillant Advanced Installers we install gas, oil and LPG boilers across Duns 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 Duns 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 Duns (TD11) installation runs efficiently from day one rather than short-cycling through the first winter.
Travel from our Kelso base: 30 minutes via the A6105.
Every new boiler we install in Duns is registered with Building Standards on your behalf and the warranty paperwork is handed over before we leave site.

Yes — Polwarth, Greenlaw, Gavinton, Allanton and the wider TD11 patch are part of our normal Duns round, with most farm and steading work booked in within the week.
Yes — we design and zone larger heating systems properly, including zoned weather compensation and underfloor heating where it makes sense.
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.
