"Top class service from start to finish. Our old boiler failed right in the middle of a cold spell. Got a transparent fixed price online without any pushy salesmen visiting. The heating team arrived punctually at 8 AM, protected our carpets, and had full heating and hot water up and running by mid-afternoon."
"Delighted with the work in our tenement flat. Replacing a boiler with high ceilings and tricky flue runs can be daunting, but Online Boiler Company handled everything with complete craftsmanship. Tidy copper work, neat magnetic filter, and the exact fixed price quoted online."
"I cannot believe how easy this process was. My boiler was condemned and within 3 days I had a new one fitted at a fantastic price - easily beating their competitors. Scott & Paddy are an absolute credit to your company."
"Was a bit apprehensive in dealing online with a heating company... Scottie and Paddy arrived early, these guys know their job, very friendly explained everything... satisfied customer!"
"Absolute 5-star service from start to finish! We needed a boiler replacement at our home in Cathcart (G44)... getting a new boiler installed for an unbeatable £1,299 was incredible value. Clean, tidy, and no hidden costs."
"Ordered on Thursday afternoon fitted and running Monday lunchtime. Couldn't beat the price hundred of pounds cheaper, and for a Worcester combi boiler... complete service old boiler removed and new boiler tested before leaving."
"Instant fixed quote online on Sunday night, engineer at our tenement flat in Shawlands Tuesday morning. No salespeople, no haggling, tidy copper pipework and full digital thermostat handover."
"Replaced our aging system boiler with an Ideal combi. The fixed price promise was 100% honored — not a penny more than quoted. Clean, polite, and great communication."

How much does an annual boiler service cost in Glasgow? +
Our annual boiler service is strictly £95 fixed price including VAT. If you are a landlord requiring both a boiler service and an official Landlord Gas Safety CP12 certificate, our combined bundle is £120 fixed.
Why is an annual service required for manufacturer warranties? +
Leading boiler brands (Worcester Bosch, Ideal, Vaillant, Navien) state in their warranty terms that the boiler must be serviced every 12 months by a Gas Safe registered engineer. Skipping an annual service will invalidate your multi-year warranty, leaving you exposed to costly repairs.
Do you provide Landlord Gas Safety Certificates (CP12)? +
Yes. By law, Scottish landlords must have a Gas Safety check completed every 12 months by a Gas Safe registered engineer. Our vetted engineers issue digital CP12 certificates directly to you and your tenants immediately following the inspection.
Are the servicing engineers Gas Safe registered? +
Yes, 100%. All annual services, safety checks, and CP12 certificates are carried out by vetted, independent, self-employed Gas Safe registered engineers who carry their official photo ID badge on every job.
