Concrete solid floors naturally lose heat directly into the ground, especially in older or uninsulated properties. Solid floor insulation in Manchester homes helps reduce this heat loss by adding a thermal layer above or below the concrete slab, improving overall energy efficiency and indoor comfort throughout the year.
By reducing heat escaping through the floor, your heating system does not need to work as hard to maintain a comfortable temperature. This can help lower energy consumption and improve overall home energy efficiency, particularly in ground-floor rooms that are used daily.
Insulated floors help eliminate the feeling of cold surfaces underfoot, making living spaces significantly more comfortable. This is especially beneficial in kitchens, living rooms, and open-plan areas where people spend most of their time.
Where eligible, homeowners may be able to access ECO4 funding for solid floor insulation, which can significantly reduce installation costs. Eligibility depends on property assessment, EPC rating, and scheme approval requirements.
Properly insulated floors help maintain a more stable indoor temperature, which can reduce the risk of condensation forming at floor edges, skirting boards, and cold bridging points—helping to improve overall damp control within the property.
Roof windows installed within the existing roof slope. Minimal structural woInsulation installed on top of existing concrete slab, with new screed or floor finish above. Best for homes with sufficient ceiling height (minimum 2.3m after installation).rk. Most cost-effective option. Ideal for lofts with adequate headroom (2.2m+).
Insulation installed below new concrete slab. For new extensions or complete floor replacement. Best for new build or major renovation.
Insulation installed vertically at floor edges. Prevents heat loss at slab edges. Can be combined with above-slab or below-slab insulation.
We use high-performance insulation materials selected according to the floor construction, available build-up height, moisture conditions and required thermal performance. For each solid floor insulation project in Manchester, the most suitable product is specified following a site survey and technical assessment.
Typically installed at 80–120mm thickness above an existing concrete slab. PIR provides strong thermal performance with a relatively slim build-up, making it suitable where floor height is limited.
Commonly used at 100–200mm thickness below a new or replacement concrete slab. It is a cost-effective option with good load-bearing performance for extensions, renovations and major floor replacement projects.
Usually specified at 60–100mm thickness where ceiling clearance or threshold height is restricted. Its high thermal performance allows the required insulation level to be achieved with a thinner layer.
Typically installed at 80–150mm thickness in floors exposed to higher moisture levels or heavy loads. It offers high compressive strength and strong resistance to water absorption.
The final insulation thickness and U-value depend on the complete floor construction, thermal bridging, product specification and Building Regulations requirements. These are confirmed through project-specific design calculations before installation.
We assess floor condition, dampness, and ceiling height.
Remove existing floor finish, check DPM (damp proof membrane), level slab.

The cost of solid floor insulation in Manchester depends on the property type, floor area, and insulation method used. Older solid-floor properties typically require more preparation, while insulation can significantly improve comfort and reduce heat loss from ground floors.
ECO4 funding may cover part or all of the installation cost, subject to eligibility, property assessment, and scheme approval.
Ideal for typical Victorian and Edwardian terraced homes with solid ground floors.
ECO4 grant up to 100% available — your cost may be £0 if eligible.
Suitable for medium-sized properties where floor insulation significantly improves thermal comfort and reduces heat loss.
ECO4 grant up to 100% available — your cost may be £0 if eligible.
Best for larger properties with higher heat loss areas and greater insulation requirements.
| Property Type | Typical Areas | Cost Range | ECO4 Funding | Final Cost (If Eligible) |
|---|---|---|---|---|
| Terraced House | Levenshulme, Burnage | £2,000–£4,000 | Partial to 100% | £0–£2,000 |
| Semi-Detached House | Stockport, Oldham | £2,500–£5,000 | Up to 100% | £0 |
| Detached House | Bramhall, Didsbury | £3,000–£6,000 | Up to 100% | £0 |
At Compliant Retrofits, we specialise in solid floor insulation across Manchester, delivering tailored retrofit solutions that improve thermal efficiency, reduce heat loss, and manage moisture risks in both concrete and older renovation floor systems.
Our team includes experienced retrofit and damp control specialists who carefully assess your property before installation. We inspect damp proof membranes (DPM), floor build-ups, and moisture conditions to ensure your insulation system is safe, compliant, and long-lasting.
We help homeowners access ECO4 funding by managing eligibility assessments, documentation, and application processes. This makes it easier to upgrade your home with little or no upfront cost where you qualify.
We use high-quality, certified insulation products designed for durability and performance. Every installation is carried out to meet current building regulations and energy efficiency standards.
We carefully consider floor levels, thresholds, and access points to ensure a seamless finish without impacting door clearances or structural integrity. This ensures both performance and practicality in everyday use.
A: 130-200mm including insulation (80-120mm) and screed (50-75mm). Check your door thresholds and ceiling height before installation.
A: Above-slab insulation requires removing floor finishes (tiles, laminate, carpet). We can work around fixed furniture (kitchen units, island), but some disruption is unavoidable.
