Loft Insulation Scotland
Quick answer
Loft insulation is one of the most straightforward ways to keep heat in a Scottish home. This page covers recommended depths, ventilation, storage boarding and what to check in tenements, bungalows and older houses before you top up. We install through MCS-certified partners across Scotland.

Loft insulation is one of the most straightforward ways to keep heat in a Scottish home. This page covers recommended depths, ventilation, storage boarding and what to check in tenements, bungalows and older houses before you top up.
How much insulation do you need?
Current guidance recommends a much deeper layer than many older lofts have. Measuring the existing depth in a few places tells you how much to add. Mineral wool rolls laid in two layers, the second across the joists, reduce gaps.
Ventilation and condensation
Lofts must stay ventilated at the eaves to avoid condensation on the underside of the roof. Insulation should not block eaves vents, and water tanks and pipes need to stay above or wrapped within the insulation to avoid freezing.
Storage and access
If you store things in the loft, use raised boarding so the insulation keeps its full depth. Insulate and draught-proof the loft hatch too. In top-floor tenement flats, the roof space may be shared, so check with neighbours first.
Before solar panels are installed, the surveyor will check the loft for cable routes, so it is a good time to sort insulation.
Scottish housing and heat loss
Scotland's homes include solid sandstone and granite tenements, rubble-built cottages, interwar cavity-wall houses, post-war no-fines concrete and timber-framed homes, and modern estates. Each loses heat differently. Solid stone walls need breathable approaches, often internal insulation with care around damp. Cavity walls can often be filled, though driving rain on exposed west-facing elevations needs to be considered. Timber kit homes usually benefit most from loft top-ups and draught-proofing.
Windows and doors are a large share of heat loss in older homes, especially original single-glazed sash and case windows. Conservation areas and listed buildings in places such as Edinburgh New Town, Stirling and many town centres have rules about what can be changed, so check with your council before ordering replacements.
How our survey works
Every project starts with a no-obligation survey. We look at your roof orientation, pitch, shading and condition, your fuse board and meter position, where a battery or inverter could go, and how your household uses electricity through the day and across the Scottish seasons. You then receive a written quote showing the equipment, the expected generation for your roof and the full price, so you can compare it fairly. We handle the network connection paperwork with your local distribution network operator, which is SP Energy Networks in central and southern Scotland and SSEN in the north, Highlands and islands. We install through MCS-certified partners. Solar panels and batteries are 0% VAT until March 2027. Finance available, subject to status.
Frequently asked questions
Do you install solar panels and batteries across Scotland?
Yes. We arrange solar panel and home battery installations across Scotland through MCS-certified partners, covering houses, flats with suitable roofs and businesses. A surveyor checks your roof, electrics and usage before we give you a written quote.
Can I add a battery to my existing solar panels?
Usually, yes. Most existing solar systems can take a home battery, either through a hybrid inverter or an AC-coupled battery. The survey checks your current inverter, fuse board and space so we can recommend a battery that suits your system.
Is finance available?
Finance available, subject to status. Your written quote shows the full price, and we can talk you through monthly payment options if you would like to spread the cost.
How do I get a quote?
Call 0141 230 0198 or fill in the quote form. We arrange a survey of your home, then send a written, no-obligation quote showing the equipment, expected generation and full price.
Can I install loft insulation myself?
Many people do, using appropriate protective equipment. Keep ventilation clear and avoid covering electrical fittings.
What about rooms in the roof?
Rooms in the roof need insulation in the sloping ceilings and walls, which is a more involved job.
