Tilt and turn windows open two ways — tilt inward from the top for secure ventilation, or swing fully inward on side hinges for easy cleaning and emergency egress. Common across Germany and Scandinavia for decades, they’ve gained popularity in the UK for modern developments, high-rise flats, and anywhere upper-floor windows are hard to clean from outside.

Typical UK tilt & turn prices in 2026

Per-window installed cost (ex-VAT, including removal of old):

Material	Small (600×900mm)	Medium (1000×1200mm)	Large (1200×1500mm)
uPVC	£480 – £650	£620 – £840	£800 – £1,100
Aluminium	£720 – £980	£920 – £1,250	£1,180 – £1,600
Timber (engineered)	£880 – £1,200	£1,150 – £1,550	£1,450 – £2,000

For an 8-window 1930s semi fitted in tilt & turn uPVC: £5,000 – £6,700 installed. That’s roughly 15% more than equivalent casement pricing — the premium covers the more complex hinge and locking mechanism.

When tilt & turn is the right choice

• Upper-floor flats where you can’t safely clean windows from outside — tilt & turn cleans from inside
• High-rise properties where building fire regs require inward-opening escape windows
• Contemporary new-builds where the European aesthetic suits the architecture
• Secure ventilation — the tilted position lets air in at the top while the main window remains locked
• Child-safety — the tilt setting restricts opening to a narrow gap at the top, well above child reach

When tilt & turn isn’t worth it

• Ground-floor rooms where standard casement is fine and cheaper
• Victorian/Edwardian period properties where the internal-swing action visually clashes with original interior period features (curtains, shutters, window seats)
• Rooms with furniture close to the window — inward-swing needs clear space internally
• Tight budgets — the 15% premium over casement may not be justified for limited benefit

Tilt & turn vs casement — comparison

Factor	Casement (standard UK)	Tilt & turn (European)
Opens	Outward only	Tilt or inward swing
Clean from inside	No — external access needed	Yes — fully accessible
Security (when closed)	Good	Excellent (multi-point locking on all sides)
Hardware complexity	Simple hinges	Complex mechanism
Cost premium	Baseline	+15%
UK market share	~85%	~8%

Practical considerations

• Interior space: you need clearance inside for the window to swing inward. Typical clearance required: full window width plus 100mm
• Curtains and blinds: must be installed clear of the swing path — usually wall-mounted above and wide of the frame, not ceiling-mounted
• Furniture placement: plan furniture layout knowing the window will sometimes swing inward
• Weather sealing: better than casement because the sash pulls firmly against gaskets on all four sides when closed
• Energy performance: u-values comparable to casement (1.2-1.4 W/m²K). The multi-sided compression seal often gives marginally better air-tightness

Frequently asked questions

Can tilt & turn be installed in period properties?

Physically yes, but aesthetically often wrong. Victorian and Edwardian homes were designed around outward-opening casements or vertical sashes — internal-swing tilt & turn clashes with period interior features like window seats, deep reveals, and traditional curtain rails. Where period look matters, choose casement or sash instead.

Are tilt & turn windows more secure?

Yes. The multi-point locking mechanism engages the sash against the frame on all four sides rather than just the opening edge. Combined with toughened or laminated glass specifications available on most 2026 models, tilt & turn typically achieves PAS 24 security certification more easily than basic casement.

Do tilt & turn windows hinge forever?

The mechanism is more complex than a casement so there are more parts that can fail. Quality brands (Siegenia, Roto, Winkhaus) offer 25+ year hinge lifespan. Cheap imports may fail within 10-15 years. Always ask the installer which hardware brand they fit and what the hardware warranty covers.

Can I retrofit tilt & turn to an existing opening?

Yes — tilt & turn fits most standard UK window openings. Replacing an existing casement with tilt & turn is a like-for-like swap. Exceptions: very narrow openings (below 500mm wide) and certain heritage reveals with asymmetric profiles.
