FD20 or FD30?
In England, the guidance generally asks for FD20 (E20) doors in this situation, and self-closers are not usually required within a house. Scotland is different: the domestic Technical Handbook expects doors onto the protected stair enclosure to be self-closing fire doors, so closers are part of the job there. Many homeowners choose FD30 doors anyway, because they are widely available and the price difference is small. Either way, the door must be fitted properly: correct gaps, fire-tested hinges and an intumescent strip where the product requires one.
What you get:
- Product details for building control
- Frame repairs or new linings where needed
- Work coordinated with your builder
- Fire-tested hinges and intumescent strips as required
The regulations behind fire doors in Carshalton
England's framework applies in Carshalton. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors. Enforcement of fire safety law in Carshalton sits with the London Fire Brigade.
For blocks over 11 metres in Carshalton, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.
