How Much Does a New Boiler Cost in Glasgow?

What drives the price

Five factors account for nearly all the variation between quotes:

• Boiler output and brand — a 24kW entry model versus a 35kW premium unit
• Like-for-like swap or a full conversion from a back boiler or open-vent system
• Flue route and whether scaffolding or a vertical flue kit is needed
• System cleaning — a power flush or chemical flush before commissioning
• Controls — basic programmer versus smart or load-compensating controls

What should always be included

Any quote worth accepting includes the appliance, a magnetic system filter, a system clean, new isolation valves, the flue kit, commissioning, Gas Safe notification to Building Standards, manufacturer warranty registration and a full handover of paperwork.

If a price looks unusually low, check whether the filter, the flush and the warranty registration are in there.

Conversions locally housing

We still remove a lot of back boilers and gravity-fed systems. Those jobs take two days rather than one, involve removing tanks from the loft, and need pipework upgrades — but they usually deliver the biggest efficiency gain of any job we do.
