Boiler installation in Marylebone
Marylebone has Georgian terraces, mews houses, mansion blocks and flats above shops. Many buildings are listed or in conservation areas, and a lot of the property is leasehold, so approvals from the freeholder or estate come first.
Postcodes in this area include W1 and NW1. A like-for-like replacement can start with the online boiler price. Moving the boiler, a new flue route, changing the system or any unusual job is assessed at a survey first.
What we check for a Marylebone installation
- In listed buildings and conservation areas, check what is allowed before a flue is moved or changed.
- Leasehold flats usually need freeholder or managing agent consent, and parking, loading and lift access should be arranged in advance.

What to have ready
- The full postcode, and whether the property is a house, flat or rented.
- Photos of the boiler and its data label, the controls, and where the flue leaves the outside wall, taken from a normal standing position.
- Photos of the visible gas meter and gas pipe, and of the place you would like the boiler to go, if it is moving.
- Do not remove the boiler casing, climb into a loft you cannot enter safely or touch any gas fitting to take photos.
