Is it cheaper to replace a boiler in the same position in Glasgow?

Usually, yes. Replacing a boiler in the same suitable position can reduce the amount of new gas pipe, heating pipework, flue work, condensate routing, electrical alteration and making-good required.

Moving the appliance may still be worthwhile if the existing position is inconvenient or conflicts with a renovation, but it should be treated as a design choice with a cost attached rather than part of a basic replacement. In Glasgow flats, space can be valuable, so relocation can sometimes improve the room even if the installation costs more.

Doherty's published package prices apply to standard replacements and specifically note that relocation and non-standard work are quoted separately. The Glasgow boiler installation page is therefore useful for comparing the base package with any additional relocation work your property needs.
