WALL & LOFT INSULATION IN PONTYPOOL & SOUTH WALES.
INSULATION INSTALLERS
Before you spend money generating or switching your energy source, it's worth checking whether you're losing a large chunk of the heat you're already paying for. A poorly insulated home can lose a significant proportion of its heat through the loft and walls - which means every pound spent on heating (or every solar panel and heat pump you install) is working harder than it needs to.
BS Renewables installs internal & external wall, and loft insulation across Pontypool and South Wales - either as a standalone improvement or alongside solar panels, battery storage, and air source heat pumps as part of a whole-property approach to cutting energy costs.
WHY INSULATION MATTERS BEFORE (OR ALONGSIDE) RENEWABLES
Insulation and renewable energy work best together, not as separate decisions:
If you're considering an air source heat pump, good insulation helps the system run efficiently at the lower, steadier temperatures heat pumps use compared to a gas boiler.
If you already have solar panels, better insulation means the heat and hot water you're generating goes further, rather than escaping through the loft or walls.
If you're simply trying to cut your heating bills, insulation is often the single most cost-effective improvement available, with no ongoing running costs of its own.
We'll always tell you honestly if insulation should come before, alongside, or after another part of your project - it depends on your property, not a fixed order we push everyone through.
INSULATION SERVICES
LOFT INSULATION
Heat rises, and an under-insulated loft is one of the most common ways homes lose heat. Loft insulation is usually one of the quickest and most cost-effective improvements available, involving laying insulating material across the loft floor to reduce heat escaping through the roof.
We assess your current loft insulation (if any), its condition, and whether ventilation needs are met before recommending an approach.
INTERNAL WALL INSULATION
For homes where external wall insulation isn't practical or suitable - such as properties with restrictions on altering external appearance - internal wall insulation fits insulating material to the inside face of external walls. It's a good option for solid-wall properties, though it does involve some disruption to the room during installation and a small reduction in internal floor space.
EXTERNAL WALL INSULATION
External wall insulation fits an insulating layer to the outside of your property, finished with a protective render or cladding. It's particularly suited to solid-wall properties (common in many older South Wales homes) that don't have a cavity to insulate, and avoids disruption inside your home during installation.
WHICH TYPE OF INSULATION DO I NEED?
It depends on your property type, wall construction, and what you're trying to achieve:
Cavity or solid wall? Solid-wall properties (common in older housing stock) typically need internal or external wall insulation rather than cavity fill.
Planning or appearance restrictions? These can affect whether external wall insulation is suitable.
Loft accessible and in reasonable condition? Loft insulation is usually straightforward to add regardless of wall type.
Budget and disruption tolerance? Internal wall insulation is generally less costly than external, but involves more disruption inside the home during works.
A proper survey is the only reliable way to answer this for your specific property - get in touch and we'll assess it honestly.
WHY CHOOSE BS RENEWABLES FOR INSULATION?
We assess your whole property, not just the insulation job in isolation - including how it interacts with any solar, battery, or heat pump plans you have.
Honest recommendations, not a one-size-fits-all sales pitch - we'll tell you if a cheaper option genuinely suits your property just as well.
Over 10 years working on homes across South Wales, including plenty of the solid-wall, older housing stock common to this region.
One local team, so if insulation is part of a wider project with us, everything is coordinated rather than handled by separate contractors.
FAQ'S
How much does loft insulation cost?
It depends on loft size, accessibility, and whether existing insulation needs removing or topping up. We provide a free, no-obligation quote after assessing your loft.
What's the difference between internal and external wall insulation?
Internal wall insulation is fitted inside the property against external walls and generally costs less, but reduces room size slightly and causes more internal disruption. External wall insulation is fitted outside the property, avoids internal disruption, and also refreshes the exterior appearance, but is generally a larger job.
Do I need wall insulation if I already have loft insulation?
Not necessarily - it depends on how much heat your property is losing through walls specifically, which varies by construction type. We can advise after an assessment.
Will insulation cause damp problems?
Poorly installed insulation without adequate ventilation can contribute to damp or condensation issues, which is why we factor ventilation into every insulation job we do.
Should I get insulation before or after solar panels or a heat pump?
It depends on your property and current insulation levels - for a heat pump in particular, good insulation helps the system run efficiently. We can advise on the right order for your situation as part of a wider quote.
Are there grants available for insulation?
Insulation grant schemes exist and change periodically, with eligibility often linked to property type, benefits status, or EPC rating. Get in touch and we'll let you know what may currently apply to your property.
