Why choose professional loft insulation for your home?

Investing in high-quality loft insulation is one of the most effective ways to lower your monthly heating costs. By creating a thermal barrier in your attic, you can prevent significant heat loss during the winter and keep your home cooler throughout the summer months. Beyond energy savings, our insulation services help improve your property’s EPC rating, which is essential for landlords meeting current MEES requirements. By addressing thermal bridging at the source, we also help mitigate common issues like condensation and black mould, ensuring a healthier indoor environment for your family.

Our PAS 2035 retrofit and installation process

At Global Energy Insulation, we follow a rigorous, professional process to ensure every project meets the highest UK building standards. We are fully PAS 2030 compliant and PAS 2035 accredited, meaning we provide a whole-house approach to retrofitting that considers your property's specific ventilation and moisture requirements. Our journey starts with a comprehensive assessment of your roof space to determine the best insulation materials for your building type. Once approved, our experienced installers carry out the work with minimal disruption, ensuring all safety and regulatory benchmarks are met before completion.

FAQ

Frequently Asked Questions

Answers to common questions about our loft insulation, PAS 2035 retrofit solutions, and heat loss reduction services in South Wales and South West England and across South Wales.

How much does loft insulation cost in South Wales?

+

The price depends on the size of your loft and the amount of existing insulation we need to remove or top up. However, loft insulation is often seen as the most cost-effective home improvement because it usually pays for itself through energy savings within a few years. We provide clear, transparent quotes after a quick survey.

Can I still use my loft for storage?

+

Yes, but you shouldn't put boxes or suitcases directly onto the insulation material as this compresses it and stops it from working. We can install "loft legs" or raised boarding systems that create a platform above the insulation, allowing you to use the space without losing any thermal benefits.

Will loft insulation cause damp or condensation?

+

Only if it is installed incorrectly. If a DIYer blocks the airflow at the eaves, moisture can get trapped. This is why using a PAS 2035 specialist is so important. We make sure that while your home stays warm, there is still enough ventilation to prevent any damp issues.
