Loft insulation helps reduce heat loss through your roof, keeping your home warmer in winter and cooler in summer. Professionally installed loft insulation can lower energy bills, improve comfort and contribute to a higher EPC rating for your Manchester property.
In an uninsulated home, around a quarter of heat can escape through the roof. Loft insulation is one of the most cost-effective energy efficiency measures available — it can pay for itself in as little as 2–3 years, depending on your property and energy use.
Cut heat loss through the roof — typically saving around £200–£300 per year on heating for a typical Manchester home, depending on your property and usage.
With a modest installation cost and lasting performance, loft insulation typically pays for itself within a few years through energy savings.
Eligible homeowners may receive fully funded loft insulation — the ECO4 scheme runs until 31 December 2026, and eligibility is income- and benefits-linked.
Warmer in winter, cooler in summer — loft insulation improves temperature regulation throughout your home.

We offer different loft insulation options based on roof type, access and energy efficiency needs.
The most common and cost-effective option. Mineral wool rolls are laid between and over the joists to create a continuous thermal layer. Suitable for most accessible lofts — usually 100mm–270mm thick.
Blown cellulose or mineral wool for hard-to-reach or irregular loft spaces. It fills gaps evenly and provides consistent coverage — typically 150mm–270mm deep.
Applied to roof rafters, expanding to form a sealed insulating layer. Strong thermal performance, but it requires careful assessment of ventilation and roof structure — see the note below.
Thin reflective layers designed for lofts with limited depth. Works by reducing radiant heat loss and is used where traditional insulation cannot be installed.
The required thickness depends on the existing insulation level and the target energy efficiency standard for the property. Typical performance levels:
| Thickness | Approx. U-value | Performance level |
|---|---|---|
| 100mm | ~0.44 | Basic — generally below current standards; found in older installations |
| 200mm | ~0.22 | Improved — a previous standard, now considered mid-level |
| 270mm (recommended) | ~0.16 | Current recommended level under UK Building Regulations guidance — optimal thermal performance |
Loft insulation is one of the lowest-cost energy efficiency measures — and ECO4 funding may cover the full cost of installation for eligible households, depending on assessment, property suitability and scheme approval.
| Property type | Indicative cost | ECO4 funding | Your cost if fully funded |
|---|---|---|---|
| Terraced house | £400–£600 | Up to 100% if eligible | From £0 |
| Semi-detached house | £500–£800 | Up to 100% if eligible | From £0 |
| Detached house | £600–£1,000 | Up to 100% if eligible | From £0 |

We deliver loft insulation solutions designed to reduce heat loss while ensuring safe installation and long-term performance.
We assess your eligibility for ECO4 funding, guide you through the process and handle all required paperwork to make your application smooth and stress-free.
We use BBA-approved insulation products that meet strict performance standards, ensuring reliable thermal efficiency and long-lasting results.
Our experienced installers follow industry best practice to ensure insulation is fitted correctly, evenly and to manufacturer specifications for maximum effectiveness.
We carefully check roof ventilation and airflow to prevent condensation, damp issues and moisture build-up after installation.
Every property is assessed individually, so we can recommend the right insulation depth and method based on your loft structure and existing thermal performance.
A no-obligation survey to evaluate your property, explain potential savings and check funding options before any work begins.
Yes — it is one of the most cost-effective energy efficiency measures available. It typically pays for itself within a few years, depending on your property and usage, and mineral wool insulation can last 40+ years.
Yes. We can install loft legs to raise the floor level above the insulation, so it isn’t compressed. This typically adds £10–£20 per square metre.
Properly installed insulation with adequate ventilation should not cause problems. We check eaves ventilation on every job and may recommend roof vents or ridge vents if needed.
Mineral wool insulation can last 40+ years with no maintenance typically required — it does not degrade over time.
