In Perry Barr, building control is provided by Birmingham City Council or a registered building control approver (formerly an approved inspector).

Which option fits your home?

Aluminium bi-fold doors

Slim, strong aluminium frames carry large glass panels and are made with a thermal break to meet energy rules. Three to six panels are typical, with a traffic door for everyday use so you don't open the whole set. They come powder-coated in almost any colour and suit kitchens and new extensions.

French doors

A pair of hinged doors that open outwards or inwards, sometimes with fixed side panels. French doors suit narrower openings and older houses. They're the simplest and most affordable way to replace an old single back door, or to turn a window into a wider opening onto a patio.

Bi-fold and patio doors in Perry Barr: common questions

How much mess is involved?

A straight swap creates some dust around the opening, so we sheet the floor and protect nearby units. Widening an opening is messier: there's brick and plaster dust, temporary props in the room and a few days of disruption. We seal off the work area as far as practical and clear up at the end of each day.

How much do bi-fold doors cost?

A three-panel aluminium bi-fold for an opening of around 2.4 m typically costs £3,000–£5,000 fitted in the West Midlands, and wider four- or five-panel sets run to around £8,500. uPVC versions cost less. If the opening needs widening, add the cost of a steel beam, calculations and building control, which we price separately in your quote.

Does Birmingham City Council need to approve my bi-fold or patio doors?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Perry Barr is provided by Birmingham City Council or a registered building control approver, and some work is self-certified by registered installers.
