Glasgow's most trusted boiler replacement specialists. Gas Safe registered, award-winning, and committed to fixed-price honesty since day one.
The Online Boiler Company was founded in Glasgow in 2017 with a simple mission: make boiler installation honest, fast, and fairly priced.
We started as a small team of Gas Safe registered engineers tired of seeing Glasgow homeowners overcharged or left with vague quotes. We built a business around fixed pricing — the price we quote is the price you pay, every time. No call-out surprises, no hidden extras, no nonsense.
Since 2017 we've grown to serve over 30,000 customers across every G-postcode in Glasgow, winning multiple industry awards and earning excellent Google reviews from local homeowners along the way.
We're proud to be Glasgow's number one boiler company — but we've never forgotten the values that got us here: transparency, quality, and respect for our customers' time and money. We work across five Glasgow districts and 100+ local areas — find yours for area-specific pricing and service details.
We do not spread ourselves across Scotland — every engineer, van and callback is focused on Glasgow G-postcodes. Each district has a dedicated hub page with local areas, maps and pricing for your neighbourhood.
From Hyndland sandstone tenements to Bearsden semis and Partick conversions — our West End engineers know how to size combis for tight cupboards, long flue runs and shared stacks without overquoting.
Partick · Hyndland · Bearsden · Milngavie · 20 areas
Merchant City lofts, high-rise flats and Georgian townhouses need careful flue planning. We quote City Centre jobs remotely with fixed prices — no surprise access charges on install day.
Merchant City · Finnieston · Charing Cross · Garnethill · 20 areas
Bay-window terraces in Pollokshields, Victorian semis in Shawlands and newer builds in Govan — South Side properties vary hugely. We match the right boiler to your home, not a one-size-fits-all package.
Shawlands · Pollokshields · Govan · Cathcart · 20 areas
Tenement conversions in Dennistoun, family homes in Easterhouse and G72/G74 streets in Cambuslang and East Kilbride — East End is one of our busiest districts for installs and winter breakdowns.
