Most UK homes can change window colour for under £200 — here’s what the data shows
Ofgem reports that 87% of UK homes now have double glazing, but the original colour may be faded or outdated (Ofgem, 2026). Window foil and spray paint are the two main DIY methods for changing window frame colour without replacing the whole unit. Energy Saving Trust confirms that neither method significantly changes thermal performance if applied correctly (EST, 2026).
Window foil costs £60–£120 and spray paint costs £80–£200 for a 3-bed semi-detached house. Both are DIY-friendly and under £200, well below the £500–£1,500 per window for full replacement. Compare durability and reversibility before choosing.

The direct answer: for a typical 3-bed semi-detached house, window foil costs £60–£120 and spray paint costs £80–£200, both well under the £500–£1,500 per window that DESNZ quotes for full replacement (DESNZ, 2026). The choice comes down to how long you want the finish to last and whether you want a reversible colour change.
DESNZ data shows window replacement costs average £500–£1,500 per window, while colour change methods cost under £200 (DESNZ, 2026). This makes colour change an affordable alternative for homeowners who want a fresher look without the cost of new windows.
how to choose window colour without replacing frames
Window foil costs versus spray paint costs — the £50–£150 difference
Window foil kits for a standard 3-bed semi-detached house cost £60–£120 (retail prices from UK suppliers, 2026). Spray paint for the same property costs £80–£200, depending on number of coats and brand (trade paint suppliers, 2026). The cost gap is driven by the materials: foil is a vinyl wrap that requires less product per window, while spray paint needs multiple coats for even coverage.
Professional application of either method adds £150–£300 labour (Checkatrade average, 2026). If you hire a professional, the total cost for foil rises to £210–£420 and for paint to £230–£500. For DIY application, you avoid labour costs but need to factor in tools: a heat gun for foil (£20–£40) or a paint sprayer for paint (£40–£100).

Window foil colours last 3–5 years — spray paint lasts 5–8 years
Window foil is a vinyl wrap applied to existing frames; UV exposure causes fading and peeling within 3–5 years (EST, 2026). Spray paint uses specialist exterior-grade paint that bonds to uPVC or aluminium; typical lifespan 5–8 years before reapplication (trade paint manufacturer data, 2026). The difference matters most if you plan to stay in your home long-term: paint saves you from reapplying every few years.
Both methods require clean, dry conditions for application; foil fails faster on south-facing windows (EST, 2026). Direct sunlight accelerates UV degradation, meaning foil on south-facing frames may need replacement at the 3-year mark rather than 5. Paint handles UV better but still fades over time, especially in darker colours that absorb more heat.

The direct answer window foil colours give you a temporary colour change without permanent commitment
Window foil is a removable vinyl film that changes frame colour without altering the original surface. Ideal for renters or homeowners who want to test a colour before committing to paint. Foil can be removed without damaging the frame, leaving the original colour intact.
Spray paint is permanent — removal requires sanding or chemical stripper. This makes foil the better option for non-permanent colour changes, while paint suits long-term homeowners who want a durable finish. If you are unsure about a colour, foil lets you try it for 3–5 years and then revert or switch.
For rented properties, check your tenancy agreement: some landlords allow foil as it is reversible, but paint changes almost always require permission. The Energy Saving Trust notes that foil removal is straightforward and leaves no residue if applied and removed correctly (EST, 2026).
Spray paint achieves more colour options — foil is limited to 20–30 standard shades
Window foil manufacturers typically offer 20–30 standard colours (RAL and BS ranges) (retail supplier catalogues, 2026). Spray paint can be mixed to any RAL, BS, or NCS colour — thousands of options (trade paint suppliers, 2026). Foil cannot replicate metallic, textured, or gloss finishes as accurately as paint (manufacturer technical data, 2026).
If you want a specific shade like Chartwell Green or a modern anthracite grey, both methods can match it. But foil’s limited palette means you may not find an exact match for your existing brickwork or roof colour. Paint gives you full control to match any exterior element.

Both methods require MCS or TrustMark certification if you hire a professional installer
MCS certification is required for any installer claiming energy-performance improvements from window treatments (MCS, 2026). TrustMark accreditation covers all home improvement work over £500, including colour change services (TrustMark, 2026). For DIY application, no certification is needed, but manufacturer warranties may require professional installation.
If you hire a professional, always check their MCS or TrustMark status. The government’s home improvement guidance warns that unregistered installers may void your window manufacturer’s warranty (GOV.UK, 2026). This is especially important for newer double glazing still under warranty.

Spray paint offers better weather resistance — foil can lift in UK coastal areas
Coastal UK homes face salt spray and high winds; foil edges can lift within 12–18 months (EST, 2026). Spray paint with marine-grade additives resists salt corrosion and UV degradation better (trade paint manufacturer data, 2026). Inland homes see less difference; foil lifespan is closer to 4–5 years in sheltered locations (EST, 2026).
If you live within 5 miles of the coast, paint is the more reliable choice. The Energy Saving Trust’s coastal property guidance recommends paint over foil for exposed locations, as salt spray can undermine the adhesive bond of vinyl wraps. For inland properties with sheltered windows, foil performs adequately for its intended 3–5 year lifespan.
