The Honest Answer: It Depends on What You Want
If you have searched "how much do steel doors cost UK" expecting a simple number, we understand the frustration. The truth is that bespoke steel entrance doors are individually designed and manufactured, so there is no single price. But we can give you realistic ranges, explain what drives the cost up or down, and help you understand whether the investment makes sense for your property.
A bespoke steel entrance door in the UK typically costs between £3,000 and £15,000+, depending on specification. That is a wide range, so let us break down exactly what determines where your door falls within it.
Typical Price Ranges for Steel Entrance Doors
Entry-Level Bespoke: £3,000 – £5,000
At this level, you are getting a genuinely bespoke steel door — made to your exact measurements, in your chosen RAL colour, with quality hardware. This typically covers:
- Single door leaf without sidelights or fanlight
- Standard dimensions (up to approximately 1000mm x 2100mm)
- Single RAL colour finish (same inside and out)
- Standard multipoint locking system
- Basic lever handle or pull bar hardware
- Double-glazed vision panel if required
This is not a budget product. Even at the entry level, a bespoke steel door delivers SR3 security certification, powder-coated finish, thermal break construction and a lifespan measured in decades rather than years.
Mid-Range Bespoke: £5,000 – £9,000
The mid-range is where most homeowners land. At this level, the specification becomes more ambitious:
- Larger door sizes or non-standard dimensions
- Single sidelight (one glazed panel beside the door)
- Dual-colour finish — one RAL colour outside, another inside
- Upgraded hardware — brass doctor's knocker, lion head knocker, premium lever set
- Decorative glazing — etched, sandblasted or patterned glass
- Ornate panel designs — raised-and-fielded panels, moulding profiles
- Integrated fanlight above the door
Properties in areas like Beaconsfield, Esher and Wimbledon commonly specify at this level — substantial enough to make an architectural statement without venturing into the most complex configurations.
Premium Bespoke: £9,000 – £15,000+
At the premium end, the door becomes a significant architectural feature:
- Double doors with or without a central mullion
- Dual sidelights (glazed panels on both sides)
- Full surround — sidelights and fanlight creating a complete glazed frame
- Complex ornamental designs — Art Deco sunbursts, period medallions, bespoke ironwork
- Fire-rated specification (FD30 or FD60) for flats, HMOs or new builds
- Oversized dimensions — doors exceeding 2400mm height or 1200mm width
- Premium hardware — PVD-coated finishes, smart lock integration, bespoke knockers
- Architectural metalwork — fluted columns, decorative surrounds, canopy integration
Properties in Kensington, Chelsea, Holland Park and Virginia Water frequently specify at this level, where the entrance door is the defining feature of the facade.
What Affects the Cost of a Steel Door?
1. Size and Configuration
The single biggest factor. A standard single door requires less material, less fabrication time and simpler installation than a double door with dual sidelights and a fanlight. Every additional element — sidelights, transoms, fanlights — adds material, glazing, hardware and structural complexity.
Impact: A double door with sidelights can cost 2–3 times more than a single door leaf of equivalent quality.
2. Glazing Specification
Plain double-glazed units are the most economical option. Costs increase with:
- Triple glazing for improved thermal performance
- Laminated security glass (required for certain security ratings)
- Decorative glass — etched, sandblasted, leaded or stained
- Obscured patterns — for privacy without sacrificing light
- Larger glazed areas — more glass means more cost and more complex structural engineering
3. RAL Colour and Finish
A single-colour powder-coat finish is included as standard. Costs increase for:
- Dual-colour finishing — different colours on the exterior and interior faces. This requires two separate coating processes and careful masking
- Metallic or textured finishes — some RAL metallic colours require additional coating steps
- Heritage colour matching — exact matching to a Farrow & Ball, Little Greene or conservation-specified colour
Explore the full range on our RAL colours page — over 200 standard options are available, with custom matching on request.
4. Hardware and Ironmongery
Hardware ranges from functional to sculptural:
- Standard lever handles — £200–£400 fitted
- Premium pull bars — £300–£600 depending on length and finish
- Doctor's knockers — £150–£350
- Lion head knockers — £200–£500 in brass or bronze
- PVD-coated hardware — premium finish that resists tarnishing, adds £100–£300 per piece
- Smart lock systems — £400–£1,200 depending on specification
- Letterplates, numerals, spy holes — £50–£200 each
5. Fire Rating
If your property requires a fire-rated door — common in flats, HMOs, new builds and housing association properties — the specification must meet FD30 or FD60 standards. Fire-rated doors require:
- Intumescent seals and smoke seals
- Fire-rated glazing (if any vision panels are specified)
- Certified fire-rated hardware
- Independent fire testing certification
Impact: Fire rating typically adds £500–£1,500 to the base cost, depending on the rating level and glazing requirements.
6. Security Certification Level
All our doors meet SR3 security certification as standard — the highest practical rating for residential properties. This is included in the base price rather than being an optional upgrade. Some manufacturers offer lower-rated doors at lower prices, but we believe security should not be a line item you can delete.
7. Installation Complexity
Standard installation into a prepared opening is included. Costs increase where:
- Structural alterations are required — widening or raising the opening
- Listed building or conservation area considerations require specialist approach
- Access is difficult — scaffolding, restricted parking, upper-floor access
- Removal of existing door and frame is complex (stone surrounds, for instance)
How Steel Compares to Other Door Materials
Understanding the cost of steel in context requires comparing it against the realistic alternatives for a quality entrance door.
Composite Doors: £1,500 – £3,000
Composite doors are the most common mid-market option. They consist of a GRP (glass-reinforced plastic) skin over a foam-filled core, with a uPVC or timber sub-frame.
What you get: Reasonable insulation, factory-made consistency, wide colour choice, PAS 24 security certification on better models.
What you do not get: SR3 security (most composites achieve SR1 or SR2 at best), genuine bespoke sizing, long-term durability (GRP skins can fade, crack or delaminate after 10–15 years), or the material quality that justifies a premium property.
Lifespan: 10–20 years before replacement is typically needed.
Timber Doors: £2,000 – £5,000
Quality hardwood doors — oak, sapele, iroko — remain popular for period properties and conservation areas. A bespoke joinery-made timber door from a reputable workshop is a genuine craft product.
What you get: Natural material beauty, traditional craftsmanship, period authenticity, good insulation properties.
What you do not get: SR3 security (timber frames and locking points are inherently weaker), zero maintenance (timber requires repainting or re-oiling every 3–5 years), dimensional stability (timber swells, shrinks and warps with moisture changes), or resistance to forced entry comparable to steel.
Lifespan: 15–30 years with regular maintenance. Without maintenance, degradation begins within 5–7 years.
Steel Doors: £3,000 – £15,000+
What you get: SR3 security certification, 25+ year lifespan with zero maintenance, dimensional stability (no swelling, shrinking or warping), powder-coat finish that does not peel, flake or fade, Secured by Design approval, fire rating options, genuine bespoke manufacturing to any size or design.
Lifespan: 25–40+ years. The powder-coat finish is warranted for decades and the steel structure is essentially permanent.
The 25-Year Cost Comparison
When you account for maintenance, replacement and longevity, the lifetime cost picture changes significantly:
- Composite door: £1,500 initial + £1,500 replacement at year 15 = £3,000 over 25 years (plus the inconvenience of replacement)
- Timber door: £3,000 initial + £300 maintenance every 3 years (8 cycles) = £5,400 over 25 years (plus the ongoing time commitment)
- Steel door: £6,000 initial + £0 maintenance = £6,000 over 25 years (with the door still in excellent condition at year 25)
The gap narrows dramatically when you factor in the full lifecycle. And this comparison does not account for the security differential — replacing a burgled composite door, repairing frame damage and dealing with insurance claims has its own cost.
Installation Costs
Installation is a critical part of the investment and should never be treated as an afterthought. A poorly installed door — regardless of how well it was manufactured — will underperform on security, thermal efficiency and weatherproofing.
What Professional Installation Includes
Through our process, installation is handled by our own fitting team — not subcontractors. The installation typically includes:
- Pre-installation survey — precise measurement of the structural opening
- Removal and disposal of the existing door and frame
- Preparation of the opening — ensuring the structural opening is square, level and properly supported
- Installation of the new frame — mechanically fixed into the masonry with appropriate fixings
- Hanging and adjustment of the door leaf
- Hardware fitting — locks, handles, knockers, letterplates, spy holes
- Sealing and finishing — weatherproofing, draught seals, threshold detailing
- Final commissioning — testing all locking points, checking alignment, adjusting closers if fitted
- Handover — demonstration of all hardware, maintenance advice, documentation
Typical Installation Timeframes
Most single-door installations are completed in a single day. Double doors with sidelights may require a day and a half. Where structural alterations are needed, allow two to three days including making good.
Why Bespoke Costs More Than Off-the-Shelf
Off-the-shelf doors — whether composite, timber or steel — are manufactured in standard sizes on production lines. The economies of scale reduce the unit cost significantly. A factory producing 500 identical doors per week achieves material efficiencies, tooling amortisation and labour productivity that a bespoke workshop cannot match.
Bespoke manufacturing is fundamentally different:
- Individual engineering — every door is drawn, calculated and planned as a one-off project
- Custom fabrication — cutting, welding, forming and finishing to unique dimensions
- No inventory — materials are ordered for each project, eliminating bulk-purchase discounts
- Skilled labour — experienced fabricators and welders, not production-line operatives
- Quality control — each door is individually inspected against its specific specification
- Longer lead times — typically 6–10 weeks from order to installation
The premium you pay for bespoke is not a marketing markup. It reflects the genuine cost of designing and manufacturing a one-of-a-kind product to a certified standard.
ROI and Property Value
A bespoke steel entrance door is one of the few home improvements that delivers measurable returns across multiple dimensions:
Kerb Appeal and Sale Price
Estate agents consistently identify the front door as the single most impactful element of kerb appeal. A premium entrance door signals quality throughout the property. In the luxury and prime market — Chelsea, Kensington, Hampstead — the entrance door sets the tone for the entire viewing.
Research from the Federation of Master Builders suggests that a new front door can return 50–75% of its cost in added property value, with premium doors in prime locations potentially exceeding 100% ROI.
Insurance Premium Reduction
Doors with SR3 certification and Secured by Design approval may qualify for reduced insurance premiums. Some insurers offer discounts of 5–15% on buildings insurance for properties with independently certified security doors. Over 25 years, this can amount to several hundred pounds in savings.
Energy Efficiency
Modern steel doors with thermal break construction achieve U-values comparable to or better than the surrounding wall construction. Replacing a draughty old door with a properly sealed, thermally broken steel door can noticeably reduce heating costs — particularly in period properties where the original door has deteriorated.
Reduced Maintenance Expenditure
The powder-coat finish on a steel door requires no maintenance beyond occasional cleaning with soapy water. Over 25 years, the saving versus timber maintenance (sanding, priming, repainting every 3–5 years) is significant in both time and money.

Frequently Asked Questions
What is the cheapest steel entrance door available in the UK?
Imported, non-bespoke steel doors from overseas manufacturers can be found from around £1,500–£2,000. However, these are typically standard sizes, may not carry UK-relevant security certifications, and often require third-party installation. A bespoke, SR3-certified steel door from a UK manufacturer starts from approximately £3,000.
Why is there such a big price range for steel doors?
The range reflects the enormous variation in specification. A single door leaf with standard hardware costs significantly less than a double door with dual sidelights, premium bronze hardware, fire rating and bespoke decorative panels. The material and labour required for a complex door can be three to four times that of a simpler design.
Do steel doors add value to a property?
Yes. A premium entrance door is consistently identified by estate agents as one of the most impactful improvements for kerb appeal and sale price. In prime property markets, the ROI can exceed the cost of the door. Beyond sale value, steel doors reduce insurance premiums, eliminate maintenance costs and provide security that protects your property and possessions.
Is it worth paying more for SR3 over PAS 24?
SR3 (BS EN 1627) is a significantly more demanding standard than PAS 24. SR3 tests resistance against a skilled attacker with power tools for 20 minutes. PAS 24 tests resistance against an opportunistic attack with basic hand tools for 3 minutes. For high-value properties, the additional cost of SR3 certification is a worthwhile investment in genuine security rather than minimum compliance.
Can I get finance for a steel door?
Many homeowners include entrance doors in broader renovation projects funded through home improvement loans, remortgage or savings. Some door manufacturers and installers offer payment plans. We recommend discussing your project requirements with us first so you have an accurate figure before exploring finance options.
