Current building regulations states that a minimum 300mm of attic insulation is required. Some homes will only require a 'top-up'.
No, the recessed lights must NOT be covered directly with insulation. ESI installation teams will install fire rated covers over the lights, which protects them from overheating, stops the heat loss, reduces draughts and risk of condensation, improves air-tightness and insect infiltration
Our Surveyor will assess your roof ventilation and if necessary, we will install new roof tile, slate or soffit vents.
This is not uncommon, and any potential issues will be picked up during the surveying stage
