Boarding a loft can be done in two ways – standard loft boarding and raised loft boarding.
Let's look at the two methods and how they differ in price:
Standard loft boarding cost:
Method: Involves laying chipboard flooring directly on top of the existing ceiling joists (assuming they are adequate to take the additional load)
Pros: Wallet-friendly, entry-level solution and quick to install
Cons: Can squash insulation if not correctly installed, not ideal for heavier storage
Cost (materials and labour): You can expect to pay £70 per m² on average for standard loft boarding
Raised system loft boarding cost:
Method: Raises the boarding above the ceiling joists and insulation with loft brackets
Pros: Protects insulation and allows air to circulate beneath the boards, reducing the risk of condensation and damp
Cons: More expensive than standard loft boarding, takes longer to install, and can reduce loft headroom slightly
Cost: On average, you'll pay around £1,050 for a 15m² loft space

What affects your loft boarding cost
The cost of loft boarding will depend on:
The size of the space
Method of boarding (standard chipboard or a raised boarding system?)
Accessibility (tricky access could increase the install time and therefore labour cost)
The condition and strength of your loft joists (additional supports may be needed to support the additional weight)
The type and quality of boards used (entry-level chipboard vs higher-spec plywood or thermal insulation boards)
Your location (labour rates are typically higher in London and the South East due to demand)
Are loft boarding costs working out more than you hoped? Before scrapping the idea, consider boarding only the central section of your loft. Focusing on the most usable area will help reduce costs while still creating storage space.
Additional costs to consider
Although most loft boarding jobs are relatively straightforward, there are a few additional costs to consider. These include:
Installing a pull-down ladder for ease of access:
Installing a pull-down aluminium ladder can be a game-changer for accessing your loft space more easily
You're looking at paying around £377.50 for a pull-down aluminium ladder
Relocation of a loft hatch:
Decided to move the loft hatch to make better use of the space, or gain easier access?
To relocate a loft hatch and repair the old opening, budget approximately £405
Loft insulation and boarding:
If your loft does not already have adequate insulation, it makes sense to tackle this job at the same time to improve your home's thermal performance
The average cost of quilt loft insulation is around £10 per m²

Any light or electronic installation requirements
Installing a light can make your loft space much safer to access and more usable
Budget roughly £87.50 to have a lightbulb and light switch to be installed (labour only)
What does loft boarding involve?
Hire right, and your installer will carry out the following steps:
Assessment: Check your loft structure, insulation depth and accessibility
Preparation: Upgrades to existing insulation (if needed) to maintain proper airflow
Raising the floor (if needed): Raised supports to prevent your insulation from being compressed may be installed
Boarding installation: Loft boards are fitted securely to create a safe and usable surface
Finishing touches: Add-ons such as loft ladders or electrics (for lighting) are then added (if needed)

Professional loft boarding installation vs DIY
Considering installing loft boarding yourself to save on costs?
Before you get cracking, it's important you understand the risks involved:
Easy to damage your ceiling (one wrong step can result in costly damage to your plasterboard ceiling below!)
Risk of compressing insulation, reducing its thermal efficiency
Potential to overload ceiling joists not designed for heavy storage
Incorrect installation could lead to damp, condensation or ventilation issues
Future home insurance claims related to your loft or insulation could be impacted
Finally, before any boarding is installed, it's important to make sure your loft structure can safely support the additional weight.
