Loft Boarding Installation Hampshire
Loft Boarding Installation Services in Hampshire
At Loft Insulation Specialists, we help you utilise the 70% of unused loft space in most homes for seasonal items, luggage, and household overflow using our raised boarding systems that work perfectly with Knauf Earthwool and Superfoil insulation. Here’s everything you need to know about installation methods, insulation protection, and regulations to make the right decision for your Hampshire property.

Is it a good idea to board a loft?
Boarding your loft with Loft Insulation Specialists is one of the smartest home improvements you can make – creating valuable storage while protecting your Knauf Earthwool or Superfoil insulation. Here are 5 compelling reasons why it’s the right choice for most Hampshire homes.
Creates 30–70% More Usable Storage
Transform unused overhead space into practical storage for seasonal items, luggage, and household overflow. Everything stays clean, dry, and easily accessible without cluttering your bedrooms, garages, or hallways below.
Adds £2,000–£5,000 to Property Value
Estate agents confirm that a fully boarded loft significantly boosts your home’s sale price. Practical storage appeals to every buyer in Hampshire’s competitive market, backed by our professional installation documentation for future surveys.
Protects Your Insulation Investment
Our raised systems maintain the full thermal performance of Knauf Earthwool or Superfoil, preventing up to 50% efficiency loss from compression. Your energy savings continue delivering benefits for years to come.
Pays Back Faster Than Self-Storage
Monthly self-storage units cost £50–£150, so loft boarding typically pays for itself within 1–2 years. Enjoy permanent convenience without ongoing rental fees or repeated trips to offsite facilities.
Professional Installation Minimises Risk
We complete the full service in just 1–2 days, including structural joist assessment and ventilation gap preservation to prevent condensation. You receive full warranty and certification for complete insurance and resale confidence.
Will loft boarding damage my insulation?
Loft boarding over Knauf Earthwool or Superfoil insulation won’t damage it when using our raised timber systems at Loft Insulation Specialists. Boarding out a loft over insulation compresses material if you lay boards directly on top. This compression reduces thermal performance and wastes the money you spent on insulation. Boarding a loft with loft insulation underneath requires minimum 50mm clearance between boards and insulation surface.
Our customers often ask about this insulation protection issue. Boarding a loft with Knauf Earthwool or Superfoil insulation requires careful planning around pipes, cables, and ventilation gaps. We leave access hatches over water tanks and junction boxes. The Building Research Establishment recommends maintaining full insulation depth under any boarding system.

How much does loft boarding cost?
Our loft boarding costs £600–£2000 for a typical Hampshire property depending on area size and installation method. Professional installation ranges from £60–£75 per square metre. A 15 square metre boarding area would cost £900-£1200 for materials and labour, including boards, fixings, and raised supports to protect your insulation layer.
We offer free surveys and fixed-price quotes. Boarding an insulated loft requires our raised timber systems to preserve thermal performance. We also include loft ladder upgrades for an additional £600-£850.
What is the best way to board a loft?

Do I need building regulations approval for loft boarding?
Loft boarding with Loft Insulation Specialists doesn’t require building regulations approval in most cases. Storage boarding falls outside controlled work. Boarding a loft for storage differs from loft conversion, which does need approval. Our loft boarding solutions for simple storage don’t alter the building’s structure or fire safety.
Building regulations apply only if you’re creating habitable space with permanent stairs. Storage platforms with loft ladders remain exempt. Your local authority might request notification for properties in conservation areas, though this rarely affects boarding approval. We’ll confirm if you have any unusual circumstances.

Frequently asked questions
Take a look at the Frequently Asked Questions regarding our Loft Boarding Installation service.
How do I check if my loft joists can support boarding?
Standard UK loft joists support our boarding and light storage loads without reinforcement. Our raised loft boarding systems spread weight across multiple joists, reducing point loading. Boarding loft roof trusses requires checking manufacturer specifications for trussed rafter systems. We include structural assessments in our survey visits.
Our loft boarding services check joist dimensions, spacing, and condition before quoting. Joists measuring 100mm x 50mm at 400mm centres support standard boarding with light storage. Heavier items like filing cabinets need joist strengthening or should stay near load-bearing walls. We’ll advise on weight limits during your survey.
Does loft boarding affect my home insurance?
Boarding and insulating loft spaces with Loft Insulation Specialists doesn’t affect standard home insurance policies. Storage boarding falls within normal home improvements. Boarding up loft areas for storage doesn’t need insurer notification in most cases. We can provide certificates if your insurer requests documentation.
Contents stored in your loft receive the same cover as items elsewhere in your home. Check your policy limits for valuable items stored in the loft space. Some policies limit single-item values or require specified high-value items. Update your contents insurance total if boarding allows you to store significantly more possessions.
What ventilation is required with loft boarding?
Boarding loft space with us requires maintaining existing ventilation gaps at eaves and ridges. Boarding out your loft shouldn’t block soffit vents or ridge tiles. Loft boarding companies leave 50mm gaps around the loft perimeter to maintain airflow. Boarding your loft completely without ventilation gaps causes condensation problems.
Warm moist air rising from your living spaces needs to escape through the roof. Blocked ventilation traps this moisture against cold surfaces, causing dampness and potential timber decay. Our professional installers design boarding layouts that maintain adequate airflow paths.
How does loft boarding impact my NHBC warranty?
Attic boarding with Loft Insulation Specialists won’t void your NHBC warranty when installed correctly. Attic boarding follows the same guidelines as other minor home improvements. Boarding attic floor areas for storage falls outside structural alterations that affect warranty coverage. Our raised loft flooring systems don’t modify the building fabric in ways that concern warranty providers.
Contact NHBC before installation if you have concerns about specific warranty terms. They may request notification of works exceeding certain thresholds. Keep all installation receipts and certificates with your property documents. Future buyers will want evidence of our professional installation standards.
Can loft boarding improve my EPC rating?
Attic boarding out with Loft Insulation Specialists doesn’t directly improve EPC ratings but supports insulation effectiveness. A boarded attic with properly maintained insulation depth scores better than compressed loft insulation. We recommend raised systems specifically because they preserve thermal performance. Poor installation that compresses insulation could actually worsen your EPC score.
Energy assessors check insulation depth during EPC surveys. They’ll note if boarding has compressed the insulation layer. Our raised boarding systems show assessors that you’ve protected your insulation investment. This attention to detail reflects well in property surveys and buyer due diligence.
