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 Sheffield Homes Need Proper Loft Insulation
Sheffield sits at an elevated position on the edge of the Pennines, exposed to harsh weather sweeping across from the Peak District. The city's diverse housing stock ranges from stone terraces in Crookes and Walkley to 1930s semis in Ecclesall, ex-council homes in Hillsborough and stone-built properties in Dore and Totley. 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 Sheffield 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."
1930s Semi in Ecclesall — Rigid Board & Mineral Wool Combination
A homeowner in Ecclesall S11 contacted us about a partially converted loft with old 75mm fibreglass insulation. The converted section had no insulation between the rafters, while the unconverted loft floor had patchy, compressed fibreglass that was well below the current 270mm recommendation.
We installed rigid PIR board (Celotex) between the rafters of the converted section for maximum thermal performance without sacrificing headroom. Across the unconverted loft floor, we laid fresh mineral wool to the full 270mm depth, carefully fitting around pipes, cables and light fittings. Ventilation was maintained at the eaves to prevent condensation.
The combination delivered maximum performance in both areas of the loft. The homeowner reported a noticeable difference within the first week — the converted room was warmer and the boiler was running significantly less. Their estimated annual energy saving was around £380, meaning the installation paid for itself in under two years.

Benefits of Loft Insulation
Why Sheffield homeowners are investing in proper loft insulation.
Energy Bill Savings
Loft insulation to the recommended 270mm depth can save a typical Sheffield 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 Sheffield's cold Pennine 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 Sheffield 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 Sheffield 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 Sheffield 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 Sheffield 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 Sheffield where every centimetre of headroom counts.

Frequently Asked Questions
What types of loft insulation do you install in Sheffield?
We install all major loft insulation types across Sheffield: 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 Sheffield home?
Current Building Regulations recommend a minimum of 270mm of mineral wool insulation for lofts. Many older Sheffield properties — particularly Victorian terraces in Crookes and Walkley — 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 Sheffield?
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 S postcodes.
Is there a government grant for loft insulation in Sheffield?
Yes. The ECO4 scheme and Great British Insulation Scheme (GBIS) can cover part or all of the cost of loft insulation for eligible Sheffield 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 Sheffield's cold Pennine winters.
Can you pair loft insulation with loft boarding in Sheffield?
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 is the best insulation for Sheffield's stone-built properties in Dore and Totley?
Stone-built properties in Dore and Totley need breathable insulation to manage moisture effectively. Sheep's wool and mineral wool are ideal choices because they allow moisture vapour to pass through without losing thermal performance. Rigid board or spray foam can trap moisture in stone walls, leading to damp and deterioration over time. We always recommend a free survey to assess your property's specific requirements and advise on the safest, most effective insulation approach.
What Sheffield Homeowners Say
Verified reviews from loft insulation customers across Sheffield and the surrounding area.
★★★★★
"We had rigid board fitted between the rafters in our converted loft and mineral wool across the rest of the loft floor. The combination has made a huge difference — both rooms are noticeably warmer and our heating bills have dropped. Arctic were professional and thorough throughout."
Rachel & Mike H
Ecclesall, Sheffield
★★★★★
"Our Victorian terrace in Crookes had really old, thin insulation that wasn't doing much. Arctic topped it up to 270mm and the difference was immediate — upstairs rooms are so much warmer. Quick, tidy job and great value. Would recommend to anyone."
Andrew P
Crookes, Sheffield
★★★★★
"We chose sheep's wool insulation for our stone cottage and couldn't be happier. Arctic explained why breathability mattered for our property type and recommended against spray foam. The installation was done in a single day and our home feels completely different. Highly recommend."
