Door colour: Black
Standard colours
Inside and outside finishes can be discussed separately where the chosen range allows.
Heritage hardware finish
Heritage aluminium doors can use more traditional-looking handles, letterplates, knockers, and cylinders, but the finish still needs to sit naturally with the slim glazing bars.
Made to measure. We show the relevant colour and hardware options during your survey before anything is finalised.

Heritage Specification
Heritage aluminium is specified around how faithfully the final set should read as original steel joinery: the leaf layout, the glazing, the colour, the hardware, and what shapes the quote. These decisions are set out below before survey.
The important heritage decision is how the opening should read from the elevation: a simple single leaf, a balanced pair, or a broader composition with matching sidelights.
A single-leaf heritage door keeps the elevation restrained and works well on side returns, porch replacements, and narrower period openings.
Double doors suit reception rooms and garden-facing period openings where the central opening is part of the character of the facade.
Sidelights keep the same narrow heritage frame language while widening the set and bringing more light into halls, side returns, and rear extensions.
Heritage aluminium suits homeowners who want the slim steel-look character of original joinery without the cold, corrosion, draughts, and upkeep that came with it. With uPVC prices climbing, it increasingly stacks up on cost too.
Slim sightlines and fine horizontal glazing bars replicate original steel and timber joinery, so the door reads as authentic from the street. On a period elevation it sits far more sympathetically than a modern uPVC door, which is why it is a popular choice in conservation areas.
Behind the heritage detailing sits a thoroughly modern door: multipoint locking, anti-snap and anti-pick cylinder upgrades, a rigid thermally broken frame, and toughened or laminated glass options. The old-school look without the old-school vulnerabilities.
Thermally broken aluminium with double or triple glazing keeps the room warmer and quieter than the single-glazed steel it replaces, and the powder-coated finish does not rust, rot, or need repainting the way steel and timber do.
uPVC prices have risen sharply, narrowing the gap to aluminium. For a period or character entrance, aluminium is increasingly the better long-term choice: slimmer, stronger, and longer-lasting for the money. We will only steer you to uPVC where the budget or the specific opening genuinely calls for it.
Heritage aluminium doors are quoted from a measured survey rather than a fixed price, because the cost follows how the set is configured, glazed, and finished. These are the factors we price around.
Leaf configuration: single, double, or a wider set with sidelights
Glazing route: clear, obscure, decorative or leaded; double or triple
Heritage bar detailing and how closely it replicates steel joinery
Colour route: stock heritage RAL or a custom RAL match to existing metalwork
Ironmongery and security: period finishes, multipoint locking, cylinder upgrades
Structural opening work and making good where the aperture changes
Access and site conditions
Because these vary property to property, and aluminium supplier costs can move, we confirm the specification at a free survey and give a fixed written quote rather than a published price. Written aluminium quotes are normally held for around 7 days.
Glazing has a major effect on how authentic the final set feels, especially on street-facing or conservation-sensitive properties.
Clear insulated glass keeps the frame visually light and usually works best where the property already has privacy from its setting.
Decorative and leaded routes can help the new door sit more naturally alongside existing fanlights, stained glass, or neighbouring period joinery.
Obscure glass is a strong option on side entrances and street-facing doors where privacy matters but the opening still needs to borrow daylight.
Heritage-appropriate bar layouts help the final set read more like original steel joinery than a generic modern aluminium door.
The bar layout and any leaded detailing do most of the work in setting a heritage door's character. Most sets run horizontal steel-look bars: tune how many bars, whether to add a vertical, and any lead pattern to suit the property, from a clean two or three-section layout to traditional leaded glass.
Two slim horizontal bars split the glass into three even sections. The most versatile steel-look layout and the default starting point for most heritage doors.
A single horizontal bar for two larger panes: the cleanest, most open read while keeping the steel-look frame. Good where you want more glass and fewer bars.
Tall vertical divisions with no horizontal bars, emphasising height. Strong on narrower openings and taller elevations.
A fine rectangular leaded grid for a traditional Georgian feel, sympathetic to older terraces and period frontages.
Clear central panes framed by a leaded margin border, a classic Victorian and Edwardian detail that keeps the view open.
A bold 1930s geometric leaded design for character properties that want a statement entrance with genuine period reference.
Lead patterns and bar layouts are illustrative. The exact bar layout, pane sizes, and lead design are agreed around the door size at survey.
Detail & survey
Optional Upgrade
Heritage aluminium doors are all about slim divided glazing and a considered frame line. Integral blinds can be useful on larger glazed sections or side screens where privacy is needed without softening the steel-look style.
A survey-led upgrade for heritage-style glazing where the frame rhythm should stay visible.
Magnetic integral blinds
A slim magnetic slider raises, lowers, and tilts the blind inside the sealed glass unit.
Electric integral blinds
Remote operation suits larger panes, harder-to-reach glass, and cleaner contemporary rooms.
We check the glazing bar layout and pane sizes carefully because not every divided-light design is a good fit for integral blinds.
Ask about heritage door blind upgradesHeritage aluminium doors are the right choice when a property needs the slim sightlines and traditional proportions of original steel casement doors, but without the corrosion, weight, draughts, and maintenance that came with the originals. Thermally broken aluminium profiles from an approved manufacturer deliver modern thermal performance and weather sealing inside a frame that reads as period-sympathetic from the street, which is why homeowners on Victorian, Edwardian, 1930s, and conservation-area properties choose them over modern uPVC. The steel-look finish is available in deep heritage colours including black, dark green, dark blue, and dark bronze, all of which can be matched to existing windows or surrounding ironwork.

How It Works
Step 1
We measure the opening and assess how the new door should read against the property: the slim steel-look proportions, the glazing bar layout, and whether a single leaf, double leaf, or sidelight composition suits the elevation. We also check the lintel and aperture, since swapping a tired timber or steel opening for heritage sightlines can mean altering the structural opening, and flag any conservation or planning considerations.
Step 2
The frame is powder-coated to your chosen heritage RAL colour and the door is built to the measured size, with the glazing bar grid, lead pattern, glass specification (clear, decorative, or obscure), period ironmongery finish, and multipoint locking all locked together before manufacture so the finished set reads as deliberate steel-look joinery.
Step 3
Our Cii team fits and seals the frame, hangs and adjusts the leaf so it closes and locks cleanly, makes good around the old opening, and checks the multipoint locking and cylinder at handover. Assure certification and the Cii 10-year installation guarantee follow on completion.
Free Survey
Tell us the opening and the finish you want, and we will survey it, confirm the heritage aluminium doors specification, and give you a fixed written quote with no obligation rather than a generic estimate.
Before installation
The quote should cover the door set and the practical work around it: access, opening preparation, levels, planning checks, and what happens after the doors are fitted.
A single heritage door is usually fitted in a day, with double-leaf and sidelight sets taking longer. Any structural alteration to the opening is planned separately.
Swapping a tired timber or steel opening for slim heritage proportions can change the aperture. We confirm the lintel, brickwork, and making-good scope before manufacture.
Heritage aluminium is often chosen for period homes, conservation areas, and listed buildings. We can supply specification detail to support a consent application where it is needed.
Service the multipoint lock and cylinder, clean the powder-coated frame with mild soapy water, and rely on the Cii 10-year installation guarantee. No painted-steel upkeep.
Compare door types
For a period entrance the right choice comes down to whether replicating original steel character, all-round warmth and security, or budget matters most.
Best when slim steel-look proportions and conservation-appropriate character are the priority and a modern uPVC door would look wrong.
“Thoroughly recommend this company. From the first call I was given really helpful advice and fitters came out the next day. The fitter was very knowledgeable and helpful, completed the job, and gave good advice on other areas we needed looking at. Will definitely use again and have no hesitation recommending them to friends and family.”
“Good price and hassle free. The doors look brilliant, exactly what we wanted. The fitters were friendly and left everything spotless.”
“Second time using CII for different properties. Easy process, good pricing, and the work was completed exactly as promised.”
