New Boiler Installation Glasgow
Glasgow’s housing is unlike anywhere else in Scotland. Across the Southside, the West End and the East End, a huge share of homes are sandstone tenement flats, alongside four-in-a-block cottages, post-war council housing and newer flats along the Clyde. Each brings its own challenges when a boiler needs replacing – from where a flue can exit a sandstone frontage to how condensate drains from a third-floor kitchen.
O’Neil has been installing gas boilers for 30 years, and we now fit more than 400 a year across the west of Scotland. Glasgow customers are looked after by the same team that covers Paisley and East Kilbride, so your survey, installation and aftercare all come from local people.
Every quote is carried out by a Gas Safe registered engineer, not a sales agent. They’ll look at your existing system, your hot water use and the layout of your flat or house, then recommend the boiler that genuinely suits it – usually a Baxi or Worcester Bosch, as we’re an accredited installer for both.
All 20 of our engineers are directly employed – we don’t use subcontractors – and once your boiler is in, there’s someone to speak to 24/7, 365 days a year. You can read more about our gas boiler installation package, or price up your new boiler online in minutes.

Choosing the right boiler for a Glasgow home
- Tenement flats: a combi boiler is usually the best fit – no tank, no cylinder, and it frees up a press or cupboard in a flat where space is tight.
- Sandstone buildings: street-facing flues aren’t always suitable, so we plan routes to the rear elevation or use plume management kits where they’re needed.
- Larger houses and villas in areas such as Pollokshields, Newlands and Kings Park often have two bathrooms and high hot water demand, where a system boiler with an unvented cylinder can be the better choice.
- Soft Glasgow water: the city’s water comes largely from Loch Katrine and is very soft, so limescale is rarely the problem – sludge in old radiators is. That’s why every installation includes a full chemical flush and a magnetic filter.

Replacing a boiler in a Glasgow tenement flat
Before we fit a new boiler in a tenement, our engineer checks that the flue terminal meets the clearance rules for nearby windows, doors and the close; plans the condensate pipe route – internally wherever possible, because external condensate pipes are prone to freezing in a cold Glasgow snap; and confirms your gas meter and pipework can supply a modern combi. If a new flue is going through a shared external wall, we’ll let you know so you can check with your factor before work starts.
Glasgow Boiler Installation FAQs
Do I need a building warrant to replace my boiler in Glasgow?
No. In Scotland, replacing a domestic gas boiler with a net input rating of 70kW or less doesn’t need a building warrant from Glasgow City Council. The work must still meet the Scottish building standards and be carried out by a Gas Safe registered engineer – which every one of our installers is.
Can you move my boiler to a different room in my flat?
Often, yes – for example from the kitchen into a hall press. Whether it’s possible depends on where the new flue and condensate pipe can go. Our engineer will check this at your free survey and include any move in your fixed-price quote.
How long does a boiler installation take?
Most boilers are installed in a single day. Bigger jobs, such as converting an old tank-and-cylinder system to a combi or moving the boiler, can take longer – we’ll tell you exactly how long on your quote.
Who will actually fit my boiler?
One of our own engineers. All 20 are directly employed by O’Neil, so the people who fit your boiler are the same team who service it and answer your call if anything goes wrong.
