Cream windows cost roughly 15–25% more than standard white uPVC, adding around £2,000–£4,000 to a typical three-bedroom semi-detached house installation
If you are replacing windows in a 2026 UK home and want a warmer, more traditional look than stark white, cream windows are a popular choice. The colour change comes at a premium. According to the Checkatrade 2026 UK window cost guide and FENSA member survey data, cream uPVC windows cost roughly 15–25% more than standard white uPVC, adding around £2,000–£4,000 to a typical three-bedroom semi-detached house installation (Checkatrade, 2026).
Cream windows cost 15–25% more than white uPVC, adding £2,000–£4,000 for a typical three-bed semi. Total installed cost for cream uPVC is £3,500–£5,500. Compare uPVC and aluminium options before ordering.

The total cost for a standard three-bed semi with cream uPVC windows typically falls between £3,500 and £5,500, fully installed. That premium reflects the additional manufacturing step of applying a coloured foil or paint to the frame, rather than any change in structural performance.
The two main material options are uPVC and aluminium, with different price and performance trade-offs
Your choice of frame material determines both cost and thermal performance. uPVC is the cheaper option. For a typical three-bedroom semi, cream uPVC windows cost £3,500–£5,500 installed, according to the same Checkatrade data. Aluminium frames cost 30–50% more, with a typical three-bed installation ranging from £5,500 to £8,500.
Both materials are available in cream RAL colours, most commonly RAL 1015 (light ivory) and RAL 9001 (cream). Always confirm the specific RAL code with your supplier before ordering, as “cream” can vary between manufacturers.
Thermal performance differs between the two materials. uPVC frames have a thermal conductivity of approximately 0.12–0.16 W/mK, while aluminium frames with a thermal break achieve 0.18–0.22 W/mK, according to the MCS installer guide and a FENSA technical bulletin on frame U-values (FENSA, 2026). That means uPVC frames are inherently better insulators, though modern aluminium with a thermal break still performs well.
Cream windows achieve a U-value of 1.2–1.6 W/m²K for the whole unit, matching white windows when glazed with A-rated double or triple glazing
The whole-window U-value depends on three factors: the frame material, the glazing unit, and the spacer bar. Colour has no effect on this figure. A cream uPVC window with A-rated double glazing typically achieves a whole-window U-value of 1.2–1.6 W/m²K, identical to a white window with the same glazing, as confirmed by the British Fenestration Rating Council (BFRC) window energy ratings database (BFRC, 2026).
Triple glazing improves the whole-window U-value to 0.8–1.2 W/m²K but adds approximately £500–£1,000 per window. The Department for Energy Security and Net Zero (DESNZ) product characteristics database shows that triple glazing can reduce heat loss by around 30% compared to standard double glazing (DESNZ, 2026).
Energy performance is identical to white windows – colour does not affect thermal insulation
Many homeowners worry that a darker or cream colour might absorb more heat or affect insulation. It does not. The cream pigment is applied as a foil or paint layer on the frame surface. It is not a structural change, so the frame’s thermal performance remains unchanged, according to the Glass and Glazing Federation (GGF) technical note on colour and thermal performance (GGF, 2026).
The solar heat gain coefficient, or g-value, measures how much solar radiation passes through the glazing. This figure is the same for cream and white windows, typically 0.5–0.6 for double glazing, as confirmed by the BRE guide to window energy ratings (BRE, 2026). So your cream windows will not make your home warmer in summer or colder in winter than white ones would.
Quick numbers – cost, U-value, and energy savings comparison table
| Window type | Typical cost per window (installed) | Whole-window U-value (W/m²K) | Annual energy saving vs single glazing (£) | Typical lifespan (years) |
|---|---|---|---|---|
| White uPVC | £350–£500 | 1.2–1.6 | £100–£150 | 20–25 |
| Cream uPVC | £450–£650 | 1.2–1.6 | £100–£150 | 20–25 |
| Cream aluminium | £650–£950 | 1.2–1.6 (with thermal break) | £100–£150 | 30–40 |

Cream windows are a direct replacement for white windows – no planning permission or special certification is required for a like-for-like colour change
If you are replacing existing white windows with cream ones of the same type and size, you do not need planning permission. Permitted development rights cover like-for-like window replacements, including colour changes, under the Town and Country Planning (General Permitted Development) Order, as confirmed by the GOV.UK planning portal (GOV.UK, 2026).
No additional building regulations approval is needed unless you change the window type, enlarge the opening, or alter the structural opening. Cream windows are simply a colour variant of standard uPVC or aluminium windows, with identical performance and installation requirements.
Installers must be FENSA or CERTASS registered for replacement windows to comply with Building Regulations
In England and Wales, any replacement window installation must comply with Building Regulations Part L (conservation of fuel and power). The easiest way to comply is to use an installer registered with FENSA or CERTASS, who can self-certify the work. GOV.UK lists approved self-certification schemes for windows (GOV.UK, 2026).
For cream windows, confirm that the installer offers your specific RAL colour before booking. Not all fabricators stock cream foil or paint, so check their product range. TrustMark registration provides additional consumer protection, covering the quality of workmanship and offering dispute resolution (TrustMark, 2026).

No, cream uPVC windows are cheaper than aluminium. uPVC costs £3,500–£5,500 for a three-bed semi, while aluminium costs £5,500–£8,500, per Checkatrade 2026.
Common cream RAL colours are RAL 1015 (light ivory) and RAL 9001 (cream). Always confirm the specific code with your supplier, as 'cream' varies between manufacturers.
Cream windows have the same thermal performance as white because the colour is a foil or paint layer. uPVC frames achieve 0.12–0.16 W/mK, per FENSA technical data.
uPVC is cheaper and a better insulator (0.12–0.16 W/mK versus 0.18–0.22 W/mK for aluminium with thermal break). Aluminium is more durable and suits modern designs, per MCS and FENSA.
