Loft Insulation
Transforming cold houses into warm homes
Prevent heat from escaping from the roof of your home
If your home loses heat quickly, upstairs rooms feel colder than the rest of the house, or your heating bills keep climbing, your loft insulation could be outdated or insufficient.
We assess your loft properly and recommend the right insulation solution whether that’s a top-up, replacement, or insulation alongside boarding.

Is loft insulation right for your home?
Most homes can benefit from loft insulation, but the right solution depends on what’s already there.
You may need:
- A simple insulation top-up
- Removal and replacement of old or damp insulation
- Insulation combined with loft boarding for storage
That’s why we start with an assessment – to make sure you’re not paying for work you don’t actually need.
Are you ready for a warmer and more efficient home?
Loft insulation is a cost-effective way to improve the energy efficiency and comfort of their home while also reducing their environmental impact.

Frequently asked questions
Loft insulation is a technique used to apply an insulating material to the roof of a building to trap heat.
The cost of loft insulation varies depending on the type of property, but this typically ranges between £750 to £2,000+.
Mineral wool insulation, also known as rock wool or slag wool insulation, is made from natural or recycled materials and is a popular choice. Mineral wool insulation has excellent thermal performance, sound insulation, and fire resistance.
Cellulose insulation is made from recycled paper and is treated with chemicals to make it fire-resistant. Cellulose insulation has outstanding thermal performance, sound insulation, and environmental sustainability.
Sheep wool insulation is a natural and sustainable option for loft insulation. Sheep wool is known for its fantastic thermal performance, sound insulation, and moisture-wicking properties. It is also non-irritant.
The insulation type chosen will depend on factors such as your budget, environmental preferences, and specific insulation needs.
Current UK recommendations suggest loft insulation should be around 270mm thick. Many homes still have much less than this, especially older properties.
If your insulation is thin, patchy, or compressed, it may not be doing its job properly. We assess what you currently have and advise whether a top-up or replacement is needed.
Not always.
In many cases, existing insulation can be topped up. However, removal may be recommended if your insulation is:
- Damp
- Mouldy
- Contaminated
- Heavily compressed
- Poorly installed
During our assessment, we’ll tell you honestly whether removal is necessary or if a top-up will be sufficient.
Poorly installed insulation, blocked ventilation, or existing moisture issues can sometimes contribute to condensation or damp problems.
That’s why we assess airflow, ventilation, and existing conditions before recommending any work. The goal is to make your home warmer without creating new problems.
Yes.
Many homeowners want insulation and usable loft storage. We can install insulation first and then board above it correctly, ensuring warmth isn’t compromised.
We’ll advise on the best setup based on your loft structure and storage needs.
Modern loft insulation typically lasts 20–40 years if it remains dry and undisturbed.
However, older insulation materials and poorly installed systems can degrade much sooner. If your home is older, it’s worth having your insulation checked.
Most loft insulation work is completed within a day and causes minimal disruption.
Our team works cleanly and efficiently, and we’ll always explain what to expect before any work begins.
Most homes can benefit from loft insulation, but not all lofts are the same.
Factors such as roof structure, access, existing insulation, ventilation, and moisture levels all matter. That’s why we don’t recommend a one-size-fits-all solution, we assess first.
Common signs include:
Upstairs rooms feeling colder than the rest of the house
- Heating bills rising
- Uneven temperatures
- Draughts or cold ceilings
- Very thin or patchy insulation
If you’re unsure, an assessment will give you clear answers.
