An aluminium bi-fold door is a set of glazed panels that slide and fold back on a track, concertina-style, to open up a whole wall of your home to the garden. Because aluminium is so strong, the frames are slim and the panels can be large — so you get maximum glass, maximum light and an almost uninterrupted view even when the doors are closed. They’re available in configurations from 2 up to 7 panels, spanning openings up to around 6 metres, and are the go-to choice for kitchen and dining extensions across the North of England.

Aluminium bi-fold doors start from around £3,499 fully installed. Most homeowners pay between £3,500 and £7,500 depending on the width of the opening, the number of panels, glazing spec, colour and threshold type. Right now you can save up to 40% on your project. We give you a free fixed-price quote with no hidden extras — the figure we write down is the figure you pay — and finance is available to spread the cost over up to 4 years.

From order to fitting day we’re typically 3–5 weeks — we’ll confirm an exact date at survey. Fitting a bi-fold set into an existing, prepared opening usually takes 1 to 2 days, all by our own in-house team — never subcontractors. If your opening needs enlarging or a structural lintel, we’ll factor that into the schedule and quote up front. We arrive on time, lay dust sheets, work cleanly, and tidy up properly at the end of each day.

Yes — every installation comes with a CERTASS certificate of compliance, posted to you after the job is signed off. This certificate proves your new doors meet current Building Regulations for energy efficiency and is essential paperwork if you ever sell your home. There’s no extra charge and no chasing required.

Yes. Our aluminium bi-fold doors are thermally broken as standard — a polyamide barrier runs through the frame to stop heat escaping — and come with argon-filled double glazing, warm-edge spacer bars and high-performance weather seals along every panel. Triple glazing is available for the very best performance. Modern bi-folds are a world away from the draughty patio doors they replace, keeping the room comfortable year-round while flooding it with natural light.

Yes — aluminium is powder-coated, so you can choose from virtually the entire RAL colour palette in matt, satin or textured finishes. You can even specify dual-colour frames — one shade inside to match your kitchen and another outside for kerb appeal. By far the most popular choice for bi-folds is Anthracite Grey, followed by Matt Black and Slate Grey. We’ll bring samples to your free survey so you can hold them up against your home.

We cover Yorkshire (West, South, North and East), Lancashire, Merseyside and Cheshire — from Leeds to Liverpool, York to Chester, Hull to Crewe, and everywhere in between. If you’re not sure whether we reach your postcode, fill in your details below and we’ll confirm within minutes — if it’s anywhere in the North, the answer is almost always yes.

Every aluminium bi-fold door comes with a comprehensive manufacturer guarantee — up to 25 years on the powder-coated frame — covering the frames, running gear, sealed glass units and hardware, plus a workmanship guarantee on the installation itself. Because we’ve been trading from our Halifax base since 2007 and serving Yorkshire, East Yorkshire, Lancashire, Merseyside and Cheshire for nearly 20 years, you know we’ll still be here if you ever need us.

Replacing existing doors like-for-like almost never needs planning permission — it falls under permitted development. If we’re creating a new opening or widening an existing one, that’s usually still permitted development but will need Building Regulations sign-off for the structural lintel (which we handle via our CERTASS registration). Conservation areas and listed buildings have extra considerations. We’ll advise honestly during your free home survey and point you in the right direction if anything needs checking with your local council.
