Loft Insulation That Stops Heat Escaping Through Your Roof
Up to a quarter of your home’s heat can escape through an uninsulated loft. Our high‑performance loft insulation keeps warmth inside, reduces energy bills, and creates a more comfortable home all year round.

KDS Insulation Keeps the Warmth In — and the Cold Out
We insulate your loft by installing high-performance insulation across and between the joists, dramatically reducing heat loss through the roof and helping your home retain warmth. First, we assess your loft space to identify gaps, cold spots, or deteriorated insulation that may be affecting performance.
We then carefully fit mineral wool, fibreglass, or eco-friendly insulation materials to create a continuous thermal barrier. This traps warm air inside during colder months and helps maintain a consistent indoor temperature.
Crucially, we ensure proper airflow above the insulation layer to prevent condensation and protect your roof structure. This keeps your loft dry, your insulation effective, and your home comfortable — just as it should be.

Why KDS Loft Insulation
Thermal Scanning for Precision Planning
Every project begins with an infrared heat loss survey to identify cold spots and gaps. This allows us to tailor your insulation plan for maximum efficiency — something most providers skip entirely.
Safe Removal of Old Insulation
If your loft contains deteriorated or damp insulation, we’ll remove it safely and responsibly. This eliminates fire risk, pest issues, and moisture problems before new insulation is installed.
Eco-Friendly, High-Performance Materials
We offer a range of insulation types — from mineral wool and fibreglass to recycled plastic and sheep’s wool. Each option balances thermal performance, breathability, and sustainability.
Improved Comfort and Lower Heating Bills
Loft insulation helps retain warmth and reduce draughts, making your home feel more comfortable even at lower thermostat settings — and cutting energy costs month after month.
Frequently Asked Questions
How long does the installation take?
Most lofts can be insulated in a single day, depending on size and access. We’ll confirm timelines during your quote, and always aim to minimise disruption.
Do you remove old insulation first?
Yes — if your existing insulation is damp, deteriorated, or unsafe, we’ll remove it safely before installing new materials. This helps prevent fire risk, pest issues, and moisture damage
What insulation materials do you use?
We offer mineral wool, fibreglass, recycled plastic, sheep’s wool, and foil-based systems. Each option is chosen to suit your property and performance goals.
Will I need to clear the loft before installation?
Yes — we’ll need access to the loft space. If it’s used for storage, we’ll advise on what needs to be moved before installation begins.
Does loft insulation help with condensation or damp?
Yes — proper insulation helps regulate temperature and airflow, reducing the risk of condensation and moisture buildup in your loft.
Can you insulate lofts in listed buildings or older homes?
Absolutely. We tailor our approach to suit period properties, ensuring breathability and compliance with conservation requirements.
Will this improve my EPC rating?
Yes — loft insulation is one of the most effective ways to boost your EPC score, reduce energy bills, and meet future rental regulations.
Instant Comfort — and Double the Savings
Why Loft Insulation Matters
Heat Escapes Through the Roof
Without proper loft insulation, up to 25% of your home’s heat can escape through the roof — making rooms colder and energy bills higher.
Cold Air Disrupts Comfort
Poorly insulated lofts allow cold air to enter and warm air to rise away, creating uneven temperatures and constant heating demand.
Insulation Creates a Thermal Barrier
Loft insulation traps warm air inside by creating a breathable thermal layer — improving comfort, reducing draughts, and lowering your carbon footprint.
