What does a Schüco bifold door actually cost in 2026, in the UK, installed? It's the most-asked question in our inbox and the one most confidently answered with the wrong number. Here's an honest breakdown of where the money goes.
Ballpark installed cost
For a properly specified Schüco AS FD 75 aluminium bifold, supplied and installed by an authorised fabricator, current 2026 pricing lands roughly in these ranges:
| Configuration | Typical opening | Installed (ex-VAT) |
|---|---|---|
| 3-panel (2+1) | up to ~3.0m | £7,500 – £10,500 |
| 4-panel (3+1) | up to ~4.0m | £9,500 – £13,500 |
| 5-panel (4+1) | up to ~5.0m | £11,500 – £16,000 |
| 6-panel (3+3) | up to ~6.0m | £13,500 – £19,000 |
These are indicative. Two things move you within the range: glass specification and threshold detail. Two things move you above it: colour on both faces (dual-colour finish) and structural opening prep that isn't included.
Where the money actually goes
Breaking down a typical 4-panel installation at around £11,000 ex-VAT:
- Aluminium frame and profiles: ~35–40% of total. This is the raw system cost from Schüco to the fabricator.
- Glass: ~20–25%. Double-glazed argon-filled is the base; triple with warm-edge spacers adds £400–£900.
- Hardware: ~8–10%. Multi-point locking, hinges, top-track carriages.
- Fabrication labour: ~10–12%. Cutting, welding, assembly at the fabricator.
- Installation: ~15–20%. Two fitters, one to two days on site.
- Delivery, waste, sundries, warranty margin: the balance.
What genuinely adds cost
Colour and finish
Standard single-colour RAL powder-coated finish is included. Dual colour (different colour outside/inside — e.g. anthracite grey outside, white inside) typically adds around £400–£700 per door. Non-standard RAL or textured finishes add similar amounts.
Glass upgrades
Standard 28mm double-glazed units are baseline. Upgrades that matter: triple glazing (+£400–£900), acoustic laminated inner (+£300–£500 per panel), self-cleaning coating (+£150–£250 per panel), solar-control coatings for south-facing doors (+£200–£400 per panel).
Threshold specification
Flush thresholds do not cost more in themselves, but they demand a properly designed drainage channel outside — often another £500–£1,200 in groundworks that don't appear on the door quote.
Structural prep
If the existing opening needs a new lintel, wider goalposts, or DPC/cavity tray work, that is not a "door" cost — but it lands on the same project. Budget £1,000–£4,000 depending on scope.
What to reject
Quotes for Schüco AS FD 75 significantly below the ranges above (i.e. a 4-panel at £6,000 fully fitted) are almost never for the AS FD 75. They're for lookalike systems or non-Schüco bifolds being sold under a Schüco-adjacent brand name. If the supplier can't produce a Declaration of Performance and a PAS 24 test certificate for the exact system, treat the quote with suspicion.
Sourcing quotes locally
We recommend getting at least two quotes from Schüco-authorised fabricators covering St Albans and Hertfordshire. Firms like 5EC Aluminium quote the AS FD 75 alongside comparable systems, which is useful for benchmarking — their premium range covers the specifications discussed in this guide.
For manufacturer pricing context, Schüco UK publishes their approved dealer directory.
