March: secure front doors
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.
Glass in a door, and in any side panel within 300mm of the door's edge, counts as a critical location when it is within 1500mm of the floor. In England, Approved Document K expects that glass to be safety glass that breaks safely, such as toughened or laminated glass.
A composite door slab usually combines a glass-reinforced plastic (GRP) outer skin, moulded with a woodgrain texture, over an insulated core. Some cores are high-density foam, others solid timber. Timber-cored slabs tend to feel heavier and more solid when closed, while foam cores are lighter and insulate well.
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.
What a typical job includes
- Written guarantee terms and advice on building regulations sign-off
- Made-to-measure composite doorset in your chosen colour
- Removal and disposal of the old door and frame
- Multi-point lock with anti-snap cylinder
Working in March
- Postcodes covered
- PE15 and the surrounding area, including Wisbech, Whittlesey and Ely
- Coast
- March is well inland, around 32 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In March the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.4 hours of daylight, rising to about 61° and 16.6 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.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.
Choosing your composite doors
Solid timber core
A heavier slab with a timber core under the composite skin, giving a solid feel and sound when the door closes.
Hardware finishes
Handles, knockers, letterplates and numerals in chrome, satin, gold, black or graphite, chosen to match the door style.
Glass designs
Clear, obscure, bevelled or decorative glass in sealed cassettes, with toughened or laminated panes for safety and security.
Composite Doors in March: questions
How long does it take to fit a composite door?
Fitting a composite front or back door usually takes a day on site, including removing the old door and frame, fitting and adjusting the new doorset and sealing around it. Doors are made to order first, and the manufacturing lead time depends on the style and colour; it is confirmed in writing when you accept the quote.
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.
Do I need building regulations approval for a new front door?
It depends on the door and where you live. In England, replacing a glazed external door is notifiable building work and must meet the energy standard, while the position for a mostly solid door depends on how much of it is glazed. A competent person scheme installer can self-certify notifiable work; otherwise building control approves it. Wales, Scotland and Northern Ireland have their own systems, and we explain which applies before fitting.
Will a composite door fade or need painting?
Composite doors do not need painting, and the coloured skins are designed to resist fading, although any surface colour can change slightly over many years in strong sun. Clean the door with warm soapy water and a soft cloth, and avoid solvents or abrasive pads. Manufacturer guarantees apply to the finish, and the terms are confirmed in writing.
Do you cover March for composite doors?
Yes. We can quote for composite doors across March and the surrounding Cambridgeshire area, including postcode districts PE15, and nearby Wisbech, Whittlesey and Ely. Start with your postcode on the quote form and a glazier will arrange a free survey before giving you a written quote.
