Hi, I'm not sure what style you are looking for but the best Victorian fire door I could find is in the link below, I hope this helps. If not not the company is called door deals. http://www.doordeals.co.uk/getmetafile/bf9ce3c9-8a5c-4994-b503-41bd7323daea/DDINWPVICTORIANSHAKER4PFD_primary.aspx?maxSideSize=300

Hello, not sure if you have considered this or if it would work in your case but I was told by building regs that if you don't have fire doors for each habitable room you can have interlinked smoke alarms in each habitable room in addition to having them in the hallways. To get the electrician to put these in, it was half the price of having to change every door in the house to a fire door ( basic door with four panel design ). Obviously some people want to have expensive doors e.g. solid wood so these will add to the cost. If you live in a period proprerty you might not want to have smoke alarms drilled into the lovely decorative ceiling so perhaps you could have a mixture of smoke alarms upstairs and fire doors downstairs or just have them installed in a discreet place. Our electrician said they have to be minimum 30cm from the door opening.

Maybe you could speak to them - https://doorwayservices.co.uk/? They do commercial doors so I'm not really sure if it goes with your project

My experience of local councils is that they don’t know their bottom from their elbow. It’s not good enough to stare you need a certificate when they are unclear about what they want the certificate to say. Ask them to direct you to the exact regulation that says a fire door is required in this situation. Firstly it sounds like you have a cupboard for your washing machine not a habitable room so you may not need a fire door because it’s not a room. Also fire doors are used to protect the stairs so people can get out of a three storey house- if your house is two storey or the utility cupboard is off a room that already has a fire door then the requirement is unnecessary. And the regulation will help you understand what they are looking for in order for your door to comply (most likely 44mm thick, rated door frame, intumescent strips, rated for 30 minutes protection etc).
