Composite front doors in Streatham: what to know
In England, replacing a glazed external door is notifiable building work, and whether a mostly solid door counts depends on how much of it is glazed, so the installer confirms what applies. Where notification is needed, an installer registered with a competent person scheme can self-certify the work; otherwise building control approves it.
In England, if the main entrance door of a home built in 1999 or later has a level threshold, the replacement should keep it level. Making access worse than when the house was built would not comply with the Building Regulations, so the glazier checks the existing threshold and specifies a low-threshold frame where needed.
In England, Approved Document L sets the limiting standard for a new door in an existing home at a U-value of 1.4 W/m²K, or a Doorset Energy Rating of band B for a mostly solid door. Doors with more than 60% of the face glazed may instead meet band C.
Letterplates can be a security weak spot, because tools can be fed through to reach the inside handle or keys. A letterplate with an internal cowl or restrictor, or a door with no letterplate and a wall-mounted post box, reduces that risk. Keys should be kept away from the door.

- Coast
- Streatham is well inland, around 35 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Streatham the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. Dark-coloured doors in direct sun get much hotter than pale ones, so follow the manufacturer's guidance on colour for south and west-facing entrances. Glazed panels and side lights bring daylight into dark hallways, especially on north-facing elevations.
- Access and setting
- Rural doors often face open fields, driving rain and sometimes mud and animals, so robust weather seals and threshold drainage matter. Older cottages may have low or irregular openings, so doors are measured carefully and frames sized to suit.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

If the glass sits in a fire-resisting door or screen, such as a flat entrance door or a commercial corridor screen, it must be replaced with fire-rated glazing tested as part of that system. Ordinary toughened glass is not a substitute.

Composite Doors in Streatham: questions
What guarantee comes with a composite door?
Manufacturer guarantees apply to the door slab, frame, glass and locking hardware, and the terms are confirmed in writing. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered before you go ahead. Keep the paperwork with your building regulations certificate for when you sell the property.
What glass can I have in a composite door?
Composite door glass comes in sealed cassettes with clear, obscure, bevelled, leaded-effect or decorative designs. Any glass within 1500mm of the floor in a door should be safety glass, and laminated glass adds security because it stays together when struck. Obscure designs give privacy in hallways while still letting daylight in.
Do I need planning permission to replace my front door?
In England, replacing a house's front door with one of similar appearance usually does not need planning permission. Listed buildings need listed building consent for significant works, and conservation areas or Article 4 directions can restrict changes to front doors, colours and materials. Flats may need permission, so check with your council if your home falls into any of these.
Are composite doors more secure than uPVC doors?
A well-specified composite door is usually stiffer and harder to force than an older uPVC panel door, but security depends mostly on the lock, cylinder, hinges and glass. Look for a multi-point lock, an anti-snap cylinder such as TS 007 3-star or SS312 Diamond, laminated glass and a door tested to PAS 24.
