Attic flooring and access: what the job involves
Boarding an attic for storage on a raised floor so the insulation underneath keeps its full depth, with a fold-down attic ladder (a stira) and an insulated, draught-sealed hatch. A floored attic is storage space, not a room, unless it meets the Building Regulations for a habitable room.
Also asked for as: attic boarding · stira fitted · attic stairs · attic ladder · floor the attic
How the job is usually done
- Check the joists, insulation depth, wiring, tank and pipes, and the roof structure for any trusses that must not be cut.
- Agree the boarded area, leaving the eaves clear for ventilation, and whether the hatch needs enlarging.
- Fit raised supports (attic legs or new joists across the old ones) so the boards sit above the insulation.
- Top up the insulation under the boarded area before closing it in.
- Lay and screw down tongue-and-groove boards, leaving access to the tank and junction boxes.
- Fit the attic ladder in the hatch, with an insulated and draught-sealed door.
- Add a light by a registered electrician if wanted, and a handrail or grab rail at the hatch.
Attic flooring and access: what is included
Usually included
- Raised supports and boarding over the agreed area
- A fold-down attic ladder and hatch
- Draught-sealing and insulating the hatch
Usually not included — agree it separately
- Topping up the attic insulation, unless agreed (it can be grant-aided)
- A light or socket in the attic, which needs a registered electrician
- Enlarging a hatch through a cut ceiling joist or truss, which needs an engineer
- Converting the attic into a habitable room
Materials and who supplies them
- Raised attic floor legs or timber for cross joists
- Tongue-and-groove chipboard or OSB boards
- Attic ladder (timber or aluminium) with insulated hatch
- Usually supplied by the carpenter
How long it takes
Usually one to two days for most attics; longer for large floors, hatch enlargement or difficult access.
When to book
Do it at the same time as an attic insulation top-up, so the insulation is fitted before it is covered.
Attic flooring and access: the rules in Ireland
What the official sources say, checked against them on the date shown. A summary, not legal advice — follow the link to read the rule itself.
Using the attic as a bedroom, office or other habitable room is a material change that must meet the Building Regulations, including fire safety, stairs and ventilation; boarding for storage does not make it a room.

What attic flooring and access costs, and why
What jobs on Talqero came to
Not enough comparable jobs yet to publish a range here. Talqero shows a price range only once at least five comparable jobs, agreed prices or offers exist — a range from fewer would describe a handful of jobs, not the market. Post your job and compare the offers you get.
What affects the price
- Floor area to be boarded
- Raised system over insulation versus boarding directly on joists
- A new attic ladder and insulated hatch, and its type
- Enlarging or moving the hatch
- Headroom and access in the attic
- Insulation top-up underneath
- VAT: building work on a home is charged at the reduced rate of 13.5% by a VAT-registered business — unless the materials come to more than two-thirds of the price, when Revenue’s two-thirds rule applies the goods rate to the whole job. Ask whether a quote includes VAT.
Paperwork to ask for at the end
- Attic ladder manufacturer’s instructions and weight rating
- An itemised invoice showing what was boarded and the insulation under it
- The electrician’s Completion Certificate for any new light
Safety
- Most modern roofs use trussed rafters; cutting any part of a truss to enlarge a hatch can weaken the roof.
- Do not overload the attic: ceilings and joists have limits, so heavy items belong near walls.
- Leave a clear path to the water tank and keep the eaves free so the roof stays ventilated.
Attic flooring and access: before you hire
Questions to ask a tradesperson
- Will you raise the floor so the insulation is not squashed?
- Will you leave the eaves clear for ventilation?
- Is the ladder and an insulated hatch included?
- How much weight can the floor take?
What you can do yourself
Laying boards on attic legs is a manageable DIY job for a careful person; enlarging a hatch or fitting a ladder into a cut ceiling is better left to a carpenter.
What to put in your task
- How much of the attic do you want boarded?
- Do you need a new attic ladder?
- How deep is the insulation now?
- Is the hatch big enough to get boxes through comfortably?
- Would you like a light in the attic?
Photos that help
- The hatch from below, with a tape across it
- The attic from the hatch, showing joists and insulation
- The roof timbers, so trusses can be identified
- The water tank and any wiring across the joists

Questions about attic flooring and access
Does attic flooring and access need a licence in Ireland?
No licence is required for this work in Ireland (source: www.cru.ie). Ask instead for references and photographs of similar jobs.
Can I board straight onto the joists?
Only if the insulation is no deeper than the joists. In most Irish attics it is now deeper, or should be, and boarding on top squashes it and loses much of its effect, so a raised floor is the usual answer.
Can I use a floored attic as a bedroom?
Not unless it is converted to meet the Building Regulations for a habitable room, including fire safety, a proper stairs, headroom and ventilation. A boarded attic with a ladder is storage space.
What is a stira?
Stira is the name people in Ireland use for a fold-down attic ladder, after a well-known brand. Ladders come in timber or aluminium, with insulated hatches that seal against draughts.
