Boiler replacement in flats and apartments
Replacing a boiler in a flat adds two constraints a house doesn't have: someone else may need to consent, and the flue has to terminate somewhere acceptable to the building as a whole.

Consent and flue routes
Many Bath conversions are leasehold, and alterations affecting the external appearance or common parts often need freeholder or management company agreement. Flue routes on upper floors may need to travel a distance to reach an acceptable termination, and terminal position relative to neighbouring windows and balconies matters both technically and neighbourly.
Handled as part of the job
- Flue route and terminal position assessed against neighbouring openings
- Advice on what your lease or managing agent is likely to require
- Access, parking and protection of communal stairs and hallways
- Compact boiler options where cupboard space is genuinely tight
Frequently asked
- Do I need freeholder permission?
- Frequently, where the flue or external fabric is affected. Check your lease early — it's the item most likely to delay a booking.
- Is parking a problem in central Bath?
- It can be. We'll arrange permits or agree a loading plan with you rather than turning up and hoping.
- Can a flat take a system boiler?
- Yes where there's cylinder space, though most flats suit a compact combi better.
Sort consent first
Technically these are straightforward jobs. It's the paperwork that delays them, so we raise it at the quote stage rather than the week of the fit.
