Bi-fold and patio doors in Warwickshire

Bi-fold and patio doors in Warwickshire: approvals and local details

This kind of work rarely needs planning permission, but it does have to comply with Building Regulations, and some parts must be certified by a registered installer or signed off by building control. In Warwickshire, building control is provided by the district or borough council for your town or a registered building control approver (formerly an approved inspector).

If a new beam bears on a wall you share with a neighbour, the Party Wall etc. Act 1996 may apply.
With a traffic door on a bi-fold set, you don't have to open every panel to step outside.
Bi-fold and patio doors must meet a U-value of 1.4 W/m²K or an equivalent energy rating.

Options to consider in Warwickshire

Widening an opening

Turning a window into doors, or making an opening wider, means cutting the wall and fitting a new lintel or steel beam sized by a structural engineer. Building control must approve the structural work. We organise the calculations, temporary supports, steel and making good, and show these costs on their own lines in your quote.

Sliding patio doors

Two or more large panels slide past each other on a track, so nothing swings into the room or onto the patio. Sliders give the biggest uninterrupted panes and the narrowest frames, which makes them a good choice where the view matters more than opening the whole wall. Aluminium sliders also suit wide openings.

Questions about bi-fold and patio doors in Warwickshire

How long does fitting take?

Fitting doors into a ready opening usually takes one to two days. If we're widening the opening, allow another two to four days for propping, cutting, fitting the beam, inspection and making good. Manufacture usually takes four to eight weeks after the design is signed off, depending on the material and colour.

Do you cover the whole of Warwickshire?

Yes — we cover Warwickshire from our West Bromwich base, including Coventry, Solihull and Birmingham. Call 0800 088 6248 or send the form on this page to book a free survey.

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.

Who approves bi-fold and patio doors in Warwickshire?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Warwickshire is provided by the district or borough council for your town or a registered building control approver, and some work is self-certified by registered installers.
