What Is Loft Insulation?
Loft insulation is a thermal barrier installed in your roof space to prevent heat escaping through the top of your home. Up to 25% of a home's heat is lost through an uninsulated roof — making loft insulation one of the single most effective ways to reduce energy bills and improve comfort.
There are several types of loft insulation, each suited to different property types and budgets. The right choice depends on your loft's condition, how you use the space and your thermal performance goals.
Mineral Wool
Glass wool or rockwool rolls — the most common and cost-effective option, installed to 270mm depth
Rigid Insulation Board
Kingspan, Celotex and PIR boards — highest thermal performance per millimetre of thickness
Sheep's Wool
Natural, breathable and eco-friendly — excellent moisture regulation and acoustic performance
Multifoil Insulation
Thin reflective quilts like SuperQuilt — ideal for loft conversions where headroom is limited
Why York Homes Need Proper Loft Insulation
York's unique housing stock ranges from Georgian and Victorian terraces in the city centre to Edwardian homes in Clifton and Fulford, plus newer estates in Haxby and Rawcliffe. Older properties often need breathable insulation to manage moisture and protect historic building fabric. Many of these homes still have little or no loft insulation — or insulation well below the current 270mm standard.
"A well-insulated loft can save a typical York household up to £590 per year on energy bills. With energy prices remaining high, loft insulation is one of the fastest-payback home improvements you can make."
Edwardian Home in Clifton — Sheep's Wool Chosen for Breathability
A homeowner in Clifton YO30 wanted to insulate their Edwardian semi but was concerned about moisture and breathability in the older roof structure. We recommended sheep's wool insulation — a natural, breathable material that absorbs and releases moisture without losing thermal performance.
The 150mm sheep's wool was laid between joists with a second 100mm layer over the top, achieving a total depth of 250mm. Ventilation was maintained at the eaves to prevent condensation. The loft hatch was also insulated and draught-stripped.
The homeowner chose the eco-friendly approach specifically because of the property's age. They reported a noticeable improvement in comfort within the first week, with upstairs rooms staying warmer and the boiler running less frequently. Their estimated annual saving was approximately £350.

Benefits of Loft Insulation
Why York homeowners are investing in proper loft insulation.
Energy Bill Savings
Loft insulation to the recommended 270mm depth can save a typical York household up to £590 per year on heating bills — one of the fastest-payback home improvements available.
Warmer Home Year-Round
Proper loft insulation keeps heat in during York's cold North Yorkshire winters and reflects solar heat in summer, creating a more comfortable home in every season.
Increased Property Value
A well-insulated loft improves your EPC rating, which can increase your property's value and make it more attractive to buyers and mortgage lenders.
Quick Installation
Most York properties can be fully insulated in a single day. Mineral wool installations are particularly fast — causing minimal disruption to your household.
Eco-Friendly Options
Choose from natural sheep's wool, recycled glass wool or other sustainable materials. Reducing heat loss also cuts your home's carbon emissions significantly.
BBA-Certified Materials
All insulation products we install carry independent BBA certification and meet current Building Regulations — giving you peace of mind and documented compliance.
Insulation Types We Install
We work with all major insulation types to find the right fit for your York home.
Mineral Wool (Fiberglass & Rockwool)
The most common and cost-effective loft insulation. Glass wool and rockwool rolls are laid between and over joists to the recommended 270mm depth. Excellent thermal and acoustic performance. Non-combustible, rot-proof and long-lasting. Ideal for most York homes.
Rigid Insulation Board (Kingspan, Celotex, PIR)
Rigid PIR boards deliver the highest thermal performance per millimetre — making them ideal for loft conversions and rooms in roof where space is limited. Products like Kingspan Kooltherm and Celotex GA4000 are BBA-certified and widely specified by architects.
Sheep's Wool Insulation
A natural, breathable and fully sustainable insulation material. Sheep's wool absorbs and releases moisture without losing thermal performance — making it excellent for older York properties where breathability is essential. Safe to handle and chemical-free.
Multifoil Insulation
Thin reflective quilts like YBS SuperQuilt and SuperFoil that deliver excellent thermal performance in a fraction of the thickness. Perfect for loft conversions in York where every centimetre of headroom counts.

Frequently Asked Questions
What types of loft insulation do you install in York?
We install all major loft insulation types across York: mineral wool (glass wool and rockwool) at the recommended 270mm depth, rigid insulation boards from Kingspan and Celotex for maximum thermal performance, natural sheep's wool for eco-friendly breathability, and multifoil insulation like YBS SuperQuilt for loft conversions where space is limited.
How thick should loft insulation be in a York home?
Current Building Regulations recommend a minimum of 270mm of mineral wool insulation for lofts. Many older York properties — particularly Victorian and Edwardian homes in Clifton and Fulford — still have just 100mm or less. Topping up to 270mm is one of the most cost-effective energy improvements you can make.
How much does loft insulation cost in York?
Costs depend on the size of your loft, the insulation type and the current condition of your loft. A small loft typically starts from around £950, a medium loft ranges from £2,000 to £2,800, and larger or more complex lofts from £2,000 to £3,000+. All prices are subject to a full loft inspection and survey results. We provide free surveys and fixed quotes across all YO postcodes.
Is there a government grant for loft insulation in York?
Yes. The ECO4 scheme and Great British Insulation Scheme (GBIS) can cover part or all of the cost of loft insulation for eligible York households. Eligibility is typically based on income, benefits or the energy rating of your property. We can advise during your free survey whether you qualify.
Can I install loft insulation myself or should I use a professional?
While mineral wool rolls can be a DIY job in straightforward lofts, professional installation ensures correct depth, no gaps around pipes and cables, proper ventilation at the eaves and compliance with Building Regulations. Incorrect installation can reduce performance by up to 50% and cause condensation problems.
Will loft insulation make my home warmer in winter?
Absolutely. Up to 25% of heat in an uninsulated home is lost through the roof. Properly installed loft insulation to the recommended 270mm depth keeps warmth inside, reduces draughts and makes rooms below the loft noticeably more comfortable — especially important during York's cold North Yorkshire winters.
Can you pair loft insulation with loft boarding in York?
Yes — this is one of our most popular combinations. We install insulation to the full 270mm depth and then fit raised loft boarding above it, so you get maximum thermal performance without losing storage space. See our loft boarding service for more details.
What insulation is best for York's older housing stock and conservation areas?
York has many period properties and conservation area homes where breathability is critical. Sheep's wool and mineral wool are ideal because they allow moisture to pass through, preventing damp and timber rot. Rigid board and spray foam can trap moisture in older roof structures, leading to condensation and potential damage. We recommend booking a free survey with Arctic so we can assess your property's roof structure and recommend the best approach for your specific home.

"Had our loft insulation topped up from 100mm to 270mm in our 1970s semi. The difference has been incredible — the house holds heat so much better and our energy bills have dropped noticeably. Arctic were efficient, tidy and competitively priced."

★★★★★
"Arctic installed loft insulation in our period cottage with real care and attention. They took time to explain the best approach for our older property and the workmanship was excellent. Would highly recommend to anyone in the Bishopthorpe area."
