Dunbar mixes historic harbour-side properties, Victorian villas along the seafront and modern estates inland. The town sits in one of the sunniest, driest pockets in Scotland but still gets serious easterly exposure on the coast — which changes how outdoor pipework, flue terminations and heat-pump units need to be specified.
As Vaillant Advanced Installers we install gas, oil and LPG boilers across Dunbar 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 Dunbar 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 Dunbar (EH42) installation runs efficiently from day one rather than short-cycling through the first winter.
Travel from our Kelso base: 55 minutes via the A1.

Yes — we run dedicated East Lothian days that take in Dunbar, so EH42 work is scheduled efficiently rather than as a one-off long trip.
Yes — corrosion-resistant flue terminations and external pipework are well worth specifying on harbour-side EH42 properties. We do this as standard.
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.
