Before you order: openings, building regs and planning
Check the width first
A pivot door needs an opening of 1.4 to 1.8 m. If your current front door is narrower and has no sidelight, a tall hinged door such as Hampstead or Marlow (1.0–1.3 m wide, up to 2.7 m tall) keeps the opening as it is. Widening an opening is structural work, and the survey prices it.
Building regulations
Replacing a door in an existing opening is self-certified by your installer under FENSA or Certass, and you receive a building-regulations certificate. Where a new or enlarged opening is formed, your installer notifies Building Control.
Planning
Replacing an external door doesn’t normally need planning permission. Listed buildings and some conservation areas are the exception, so check with your council’s planning team before you order if either applies to your home.
Questions from Essex homeowners
Which parts of Essex do you cover?
We cover the RM, IG, CM and SS postcode areas, which include Romford, Hornchurch, Upminster, Rainham, Grays, Ilford, Woodford Green, Chigwell, Loughton, Brentwood, Billericay, Chelmsford, Basildon and Southend-on-Sea. Enter your postcode in the estimator and it tells you straight away; if no installer covers you yet, we say so and don’t pass your details to anyone.
Who will survey and fit my door in Essex?
Optimal Builders, our approved installation partner for London and Essex and a FENSA-registered installer. They survey your home, send the written quote, contract with you directly and fit the door. Your enquiry goes to them and to nobody else.
Are prices different in Essex?
No. The published guide prices are the same in every area we cover, from £4,795 for a Hampstead tall aluminium door and £8,095 for a Belgrave pivot door, supplied and fitted with VAT. The survey can add to that for awkward access, making good or a structural opening, which is what the upper figure in the estimator allows for.
How quickly can a door be fitted in Essex?
Typically 6–8 weeks from survey sign-off for standard colours and specifications. The written quote follows within 48 hours of the survey.
Do I need planning permission to replace my front door in Essex?
Replacing an external door doesn’t normally need planning permission. If your home is listed or in a conservation area, check with your district, borough or city council, or with Southend-on-Sea or Thurrock council if you live there. Building regulations do apply, and your installer self-certifies a like-for-like replacement and gives you the certificate.
