How much does a new back door cost in Ireland? For most homes, a replacement back door supplied and fitted costs between €950 and €3,500, depending on the material, the amount of glass and the state of the existing opening. A standard uPVC back door sits at the lower end of that range, composite in the middle, and aluminium or fully glazed designs at the top.
This guide breaks down current 2026 prices for each type of back door, explains what pushes a quote up or down, and shows you how to compare quotations properly so you are not paying for things you don’t need.
Key Takeaways
- A fitted uPVC back door typically costs €950 to €1,600 in Ireland.
- A fitted composite back door typically costs €1,700 to €2,800.
- A fitted aluminium back door typically costs €2,200 to €3,500.
- Glazing, colour, hardware and the condition of the frame opening are the biggest price variables after material.
- Always ask for a supply-and-fit price that includes removal and disposal of the old door.
Prices are typical ranges for 2026 and are a guide only. Every home is different, so use them to sanity-check quotes rather than as a fixed price list.
Back Door Prices in Ireland by Material
Material is the single biggest factor in what you’ll pay. The table below shows realistic supply-and-fit ranges for a standard single back door, around 900 mm wide by 2,100 mm high, replacing an existing door in the same opening.
| Back door type | Typical fitted price (2026) | Best for |
|---|---|---|
| uPVC, solid or half-glazed panel | €950 to €1,600 | Budget replacements, rental properties, utility rooms |
| uPVC, fully glazed | €1,100 to €1,800 | Dark kitchens that need more light |
| Composite | €1,700 to €2,800 | Security, insulation and long-term durability |
| Aluminium | €2,200 to €3,500 | Contemporary homes and extensions, slim frames |
| uPVC French doors as a back door | €1,600 to €2,600 | Wider openings onto a patio or garden |
uPVC Back Door Cost
uPVC back doors remain the most popular choice in Ireland because they deliver a secure, low-maintenance door at the lowest price. A white uPVC back door with a solid lower panel and a double-glazed upper section, fitted with a multi-point lock, generally comes in between €950 and €1,600.
Expect to pay towards the top of that range for a foiled colour such as anthracite grey, a fully glazed design or obscure privacy glass.
Composite Back Door Cost
Composite back doors have a solid insulated core wrapped in a tough GRP or uPVC skin. They are heavier, more rigid and better insulated than uPVC, and they hold their colour for longer. A fitted composite back door in Ireland usually costs €1,700 to €2,800, with woodgrain finishes and glazed designs at the upper end.
If your back door opens directly into a living space or kitchen rather than a utility room, composite is often the better value over 20 years even though it costs more up front. Our full uPVC vs composite doors comparison goes into the trade-offs in detail.
Aluminium Back Door Cost
Aluminium back doors give the slimmest frames and largest glass areas, which is why they are the standard choice for modern extensions. Thermally broken aluminium frames insulate well, but the material and fabrication cost more, so a fitted single aluminium back door typically runs €2,200 to €3,500.
Glazed Back Doors and French Doors
If your back door is more about light and garden access than a service entrance, a pair of uPVC French doors is often the better option and costs €1,600 to €2,600 fitted for a standard opening. Wider sliding or bi-fold openings are a different project and are covered in our patio doors range.
What Changes the Price of a Back Door?
Two quotes for “a uPVC back door” can differ by several hundred euro. These are the factors that account for the gap.
1. Glazing
More glass means more cost. A solid panel door is cheapest, a half-glazed door costs a little more, and a fully glazed door costs the most. Upgrading from double to triple glazing adds roughly €100 to €250 on a single door, and obscure or patterned privacy glass adds a smaller premium.
2. Colour and Finish
White uPVC is the baseline. Foiled colours such as anthracite grey, black or a woodgrain finish add around 10 to 20 percent to a uPVC door. On composite doors the colour is usually included in the price, and on aluminium a standard RAL powder coat is included with premium textured finishes costing extra. See our RAL colour chart for the most popular door colours in Ireland.
3. Hardware and Security
A multi-point locking system should be standard on any new back door. Upgrades that add cost include anti-snap cylinders, higher-security locks, letterboxes, cat flaps, and premium handles in black or stainless steel. Our guide to the best door locks for Irish homes explains which upgrades are worth paying for.
4. Size and Opening Condition
Standard-size doors are cheaper because they don’t need bespoke fabrication. Non-standard heights, wide openings and doors with side panels cost more. The state of the existing opening also matters: if the reveal needs building up, the threshold needs replacing or the plaster around the frame has to be made good, that labour is added to the quote.
5. Side Panels and Top Lights
Adding a glazed side panel or a top light turns a single door into a larger frame assembly. Budget roughly €300 to €700 extra for a side panel depending on material and glazing.
6. Location
Labour rates in Dublin and the commuter counties tend to be higher than in rural areas, and access issues such as apartment blocks or tight side passages can add to fitting time.
What Should a Fitted Back Door Quote Include?
When you compare back door prices in Ireland, make sure each quotation covers the same scope. A proper supply-and-fit price should include:
- A site survey and accurate measurement of the opening
- The door, frame, threshold and glazing as specified
- Multi-point lock, cylinder, handles and hinges
- Removal and disposal of the old door and frame
- Fitting, sealing and weatherproofing
- Making good internally and externally, or a clear statement that it is excluded
- The warranty on the door, the glass and the installation
If a quote looks unusually cheap, check whether disposal, making good or VAT have been left out. Our article on questions to ask before buying windows and doors is a useful checklist to bring to any quotation meeting.
Is It Worth Replacing Your Back Door?
Back doors work harder than any other door in the house. They are opened dozens of times a day, face the weather and are the most common target for burglars because they are out of sight of the street. Replacing an old, draughty or poorly locking back door pays back in three ways:
- Security. Modern multi-point locks and reinforced frames are a significant upgrade on a 20-year-old door with a single mortice lock.
- Heat loss. A well-fitted, insulated door removes one of the biggest draught points in the house, which matters in kitchens and utility rooms that are already hard to heat.
- Everyday use. No more sticking, forcing or lifting the door to get the key to turn.
If you are already planning window upgrades, replacing the back door at the same time usually works out cheaper than doing it separately, because the survey, fitting team and scaffolding or access costs are shared. Our window and door replacement cost guide covers whole-house budgets.
Are There Grants for a New Back Door?
Replacing a door on its own is not usually covered by an individual SEAI grant. External doors can be included when they form part of a wider home energy upgrade, and eligible households may have them covered under the Warmer Homes Scheme. Our window and door grants guide explains the current schemes and who qualifies.
Frequently Asked Questions
How much does a uPVC back door cost fitted in Ireland?
A standard uPVC back door supplied and fitted typically costs €950 to €1,600 in 2026. Fully glazed designs, coloured foils and privacy glass push the price towards the upper end.
How much is a composite back door in Ireland?
Expect €1,700 to €2,800 fitted for a composite back door. Composite costs more than uPVC but is stronger, better insulated and keeps its finish for longer.
Is a composite back door worth the extra cost over uPVC?
For a door into a kitchen or living space, usually yes, because of the better insulation, security and durability. For a utility room or side entrance that is rarely used, a good uPVC door is often the sensible choice.
How long does it take to fit a new back door?
A straightforward like-for-like replacement is normally completed in half a day. Doors with side panels or openings that need building work can take a full day.
What is the standard back door size in Ireland?
Most Irish back doors are around 900 mm wide and 2,100 mm high, but older houses vary a lot. All quality replacement doors are made to measure, so a non-standard opening does not usually mean a non-standard price unless it is unusually large.
Can I get a back door that matches my front door?
Yes. Composite and uPVC ranges typically offer matching colours and glass designs across front and back doors, so you can keep a consistent look on both sides of the house.
Final Verdict: What Should You Budget for a New Back Door?
For most Irish homes in 2026, budget €1,000 to €1,600 for uPVC, €1,700 to €2,800 for composite, and €2,200 to €3,500 for aluminium, fitted. Choose uPVC for value on a lightly used door, composite where security and warmth matter most, and aluminium for a modern extension where slim frames and large glass are the priority.
