LMG Home Improvements is and MCS Accredited installer who provide professional Solar PV and battery storage solutions with quality equipment, correct system design, and safe installation standards. We focus on long-term performance, reliability, and helping homeowners maximise savings from their renewable energy system.
Yes. Solar PV pairs well with upgrades such as insulation, heat pumps, EV chargers, and smart energy tariffs. Combining measures can significantly improve energy efficiency and reduce overall energy costs.
Yes. When designed and installed correctly by qualified professionals using compliant equipment and protections, Solar PV and batteries are safe and reliable systems.
Solar PV requires very little maintenance. Periodic visual checks and performance monitoring are recommended. Batteries are usually maintenance-free, and system performance can be monitored via an app.
Disruption is minimal. Most work takes place externally on the roof and internally near the consumer unit/inverter location. Power may need to be isolated briefly during electrical connection and commissioning.
Most Solar PV systems are installed within one to two days. Battery storage installation is typically completed alongside the solar installation, although it can vary depending on electrical works required.
Many properties are suitable, but installation depends on roof condition, direction, pitch, shading, and structural suitability. South-facing roofs are ideal, but east/west-facing roofs can still perform very well.
Most domestic solar installations fall under permitted development rules, but exceptions apply (for example, listed buildings, conservation areas, or certain roof layouts). A site assessment will confirm requirements.
Most standard Solar PV systems automatically shut down during a power cut for safety. Some battery systems can provide backup power functionality, but this requires specific equipment and system design.
Battery lifespan depends on the brand, capacity, usage patterns, and operating temperature. Most modern batteries come with warranties based on years and/or cycles (charge/discharge cycles).
Solar PV panels are designed to last for decades and typically come with long manufacturer performance warranties. Output gradually reduces over time, but systems commonly continue producing usable energy well beyond warranty periods.
It can. Solar PV and battery systems are often seen as desirable upgrades because they reduce ongoing energy costs and improve EPC performance in many cases, which can be attractive to buyers.
If you generate more power than you use, the surplus can either be stored in your battery (if installed) or exported back to the grid. Some households may receive export payments depending on their tariff.
Battery storage is most effective when paired with Solar PV. In some cases, batteries can also be charged using off-peak electricity tariffs to lower running costs, depending on your energy supplier and tariff.
Solar PV can still be worth it without a battery, especially for households with high daytime electricity use. However, a battery usually improves overall value by storing excess power and reducing evening grid usage.
Savings depend on your system size, roof orientation, shading, and how much energy you use during the day. Adding battery storage typically increases savings because more of the energy generated is used within the home rather than exported.
Yes. Solar PV works in daylight and still generates electricity on cloudy days, though output is lower. In winter months, generation is reduced due to shorter days, but the system still contributes to household electricity usage.
Solar PV with battery storage is considered a premium upgrade because it reduces household energy costs, improves energy independence, adds long-term value, and supports lower carbon living. Batteries also improve performance by making solar energy usable when panels are not generating.
A solar battery stores surplus electricity generated by your solar panels during the day so it can be used later, such as in the evening or overnight. This increases self-consumption and reduces the amount of electricity you need to buy from the grid.
Solar PV (photovoltaic) is a system of solar panels that converts daylight into electricity for your home. Panels can be installed as roof-mounted systems (fixed above existing tiles) or as in-roof systems (integrated into the roof structure for a lower-profile finish). Solar PV helps reduce reliance on the grid and can lower electricity bills.
Cavity wall insulation removal should only be undertaken by experienced specialists such as LMG Home Improvements, using professional diagnostic techniques and specialist extraction systems.
Resolving damp and moisture-related defects can improve property condition, mortgage suitability, and buyer confidence, which may positively affect property value.
Yes. When undertaken by trained specialists using appropriate equipment, the process is safe and compliant with current building and health standards.
Yes. A professional survey is essential to determine whether cavity wall insulation is causing the issue and whether removal is the correct solution.
LMG Home Improvements provides guarantees on workmanship in line with industry standards. Guarantee terms depend on the scope of works and findings of the survey.
If the insulation is a contributing factor, removal can significantly reduce or eliminate damp problems. A full assessment is required to identify and address all sources of moisture.
Yes. After removal and an appropriate drying period, replacement insulation or alternative energy efficiency measures may be installed if the property is suitable.
Removing defective insulation often improves comfort by eliminating moisture retention and cold bridging. Once the cavity is dry and suitable, alternative insulation solutions can be considered.
Most residential properties can be completed within one to two days, depending on the size of the property, insulation type, and site conditions.
Disruption is minimal. Work is carried out externally, and all access points are repaired to blend with the existing brickwork, render, or wall finish.
Cavity wall insulation is removed by creating controlled access points to the external wall. Small access holes are drilled, and bricks are removed just above the damp proof course (DPC) level to allow full access to the cavity. Compressed air is blown through the cavity to loosen the insulation, which is extracted at exit points at DPC level using an industrial vacuum system. Insulation is also removed below DPC level to prevent future moisture from tracking across insulation between the external and internal wall skins. Once removal is complete, the cavity is inspected, cleared where necessary, and all access points are professionally reinstated to match the existing wall finish.
Most insulation types can be removed, including mineral wool fibre, polystyrene beads, bonded bead systems, and certain foam-based installations, subject to a site inspection.
Common indicators include persistent damp or mould on internal walls, peeling wallpaper or paint, musty odours, cold internal wall surfaces, and moisture issues that continue despite adequate ventilation. A professional survey is required to confirm the cause.
Faulty insulation can result in internal damp patches, mould growth, condensation, cold bridging, reduced energy efficiency, timber decay, corrosion of wall ties, and damage to internal plaster and decorations.
Cavity wall insulation may need to be removed if it has become wet, damaged, displaced, or ineffective. Common causes include rubble or debris left in the cavity during the original construction, which can trap moisture and cause insulation to become sodden. Insulation may also require removal if it was incorrectly installed, leaving voids or uneven coverage within the cavity that allow water to track across to the internal wall leaf. Defects can also occur following window or door replacements, where changes to frames, lintels, or surrounding materials can dislodge insulation or compromise the cavity, leading to damp issues, cold spots, and reduced thermal performance.
Cavity wall insulation removal is the process of safely extracting insulation materials from the cavity between external walls. This is typically required when insulation has become damp, damaged, poorly installed, or is contributing to property defects such as condensation, mould, or penetrating damp.
External wall insulation can help reduce condensation and penetrating damp by keeping walls warmer and better protected from the weather. For best results, insulation should be installed alongside proper household ventilation, in line with PAS 2035 retrofit best practice. This may include background trickle ventilation, mechanical extract ventilation in wet rooms such as bathrooms and kitchens (DMEVs), or whole-house systems such as Positive Input Ventilation (PIV). This balanced approach helps control moisture levels, improve indoor air quality, and reduce the risk of mould.
Most residential installations are completed within two to four weeks, depending on the size and condition of the property. Some stages of render application are weather dependent, and timescales may be adjusted to ensure the best possible finish. Every effort is made to minimise disruption.
Planning permission is not usually required. However, listed buildings or properties in conservation areas may need approval. This should always be checked before work begins.
Yes. External wall insulation can significantly improve the appearance of your property. With a wide choice of colours and finishes available, it can modernise your home or maintain a traditional look.
We offer a range of finishes including silicone-enhanced render, dash render, and brick slip finishes, or a mix of these finishes. These options allow homeowners to choose a style that suits both modern and traditional properties.
We install render systems from several leading manufacturers. Our preferred system is Johnstone’s Stormshield, chosen for its durability, weather resistance, and high-quality finish, helping to protect your property while delivering long-lasting performance.
Yes. By reducing heat loss through your external walls, insulation helps your home stay warmer for longer. This means your heating system works more efficiently, helping to reduce energy consumption and lower household bills.
External wall insulation is suitable for most property construction types, including solid wall, cavity wall, brick, block, concrete, and many system-built and rendered properties. It can be installed on houses, bungalows, and low-rise residential buildings where the external walls are structurally sound. Final suitability is confirmed following a professional survey.
External wall insulation involves fixing an insulating layer to the outside of your property’s walls, which is then finished with a durable render or cladding system. This creates a continuous thermal barrier while also improving the look of your home.
External wall insulation helps your home retain heat, reduces energy bills, improves indoor comfort, and protects your property from the elements. It also enhances the appearance of your home and can increase its overall value.
