Most Solihull lofts have just 100–150mm of compressed, dust-clogged insulation losing 40% of its rated performance. A proper top-up to 270mm pays for itself inside three winters and adds a full grade to your EPC.
Topping up existing loft insulation to the current 270mm Building Regs Part L1B standard using mineral wool, sheep's wool or recycled PET batts. Includes pre-survey thermal check, pipe lagging, eaves ventilation protection and insulated hatch upgrade.
Any home built before 2008, that's roughly 80% of housing stock in Solihull, Sutton Coldfield and Bromsgrove. Especially urgent for homes with first-floor cold rooms, ice on internal walls or escalating gas bills.
Before next winter. Insulation pays back fastest when fitted September–November, ahead of peak heating demand. Government-funded ECO4 grants are also available year-round for eligible households.
Insulation older than 15 years has typically settled to 60–70% of its installed depth and lost 30–40% of its thermal performance. Topping up adds an immediate £180–£320/year saving on heating costs at current price-cap rates.
Loft insulation is the single highest-ROI energy upgrade in UK housing. Ignoring it costs more than installing it, every single winter.
We measure existing insulation depth at six points, check for damp, vermin and ventilation, and confirm whether you qualify for ECO4 funding.
Old, contaminated or vermin-affected insulation removed and disposed of. Pipework lagged. Eaves ventilation tray fitted to maintain cold roof airflow.
100mm mineral wool fitted between joists, butted tight, no gaps.
Second layer of 170mm laid perpendicular across the joists, eliminating thermal bridging through the timber.
Insulated hatch fitted, EPC re-rating advice and your guarantee.
Based on Energy Saving Trust figures for an average 3-bed semi at current price-cap rates.
Standard 270mm top-up at £495–£795 returns its full cost in heating savings inside three years.
Most homes gain a full EPC band, directly increasing valuation and rentability.
270mm of mineral wool also acts as an acoustic baffle, noticeably quieter to road and aircraft noise.
Households on qualifying benefits get insulation fully or partially funded, we handle the application.
Sheep's wool, recycled PET and natural hemp insulation available for chemically-sensitive households.
Loft insulation is one of the most measured, regulated and well-understood energy products in the UK, yet most lofts we open are fitted wrong. The materials matter, but the install detail matters more.
Knauf Earthwool mineral wool: most cost-effective, BBA-certified, 0.044 W/mK. Sheep's wool: hygroscopic, breathable, ideal for older properties with damp risk. Recycled PET batts: rigid, easy to detail, no fibre exposure, good for self-clean loft environments.
Building Regs Part L1B (2022 update) requires 270mm of mineral wool equivalent to achieve a U-value of 0.16 W/m²K. Anything less fails current new-build standards and underperforms on EPC modelling.
Joists themselves conduct heat. The first 100mm goes between the joists; the second 170mm is cross-laid perpendicular over the top, breaking the thermal bridge and gaining roughly 12% extra real-world performance.
Insulation must never block the eaves gap between rafter and wall plate. We fit rigid plastic ventilation trays at every rafter to maintain the cold-roof airflow that prevents condensation and rot.
All exposed copper pipework gets 19mm closed-cell lagging. Cold water tanks get a fitted jacket, both legal requirements under Water Regs and free with every install.
Households receiving qualifying benefits, or in low-EPC properties (E, F, G), may qualify for fully-funded loft insulation under the ECO4 scheme. We're a registered installer and handle the full application.
