Haddington is the largest of the East Lothian towns we cover and the busiest non-Borders patch on our books. The mix of historic stone properties around the High Street, post-war estates off Aberlady Road and a lively commuter scene out toward Edinburgh creates strong demand for combi swaps, full bathroom refits and increasingly heat-pump enquiries.
As Vaillant Advanced Installers we install gas, oil and LPG boilers across Haddington 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 Haddington 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 Haddington (EH41) installation runs efficiently from day one rather than short-cycling through the first winter.
Travel from our Kelso base: 1 hour 10 via the A697 / A1.
Every new boiler we install in Haddington is registered with Building Standards on your behalf and the warranty paperwork is handed over before we leave site.

We're Borders-based but East Lothian is part of our regular weekly round — we run dedicated Haddington and coastal days, so EH41 work is scheduled around them rather than as a one-off.
Yes — we plan flue routing and external pipework carefully on conservation-area elevations and flag any consents needed before quoting.
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.
