What is a loft insulation top-up?

Questions about a loft insulation top-up in Bath

Can a landlord in Bath book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Can you visit Bath outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

How soon can you visit a home in Bath?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

Which way should the top-up layer run?

Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.

Is it worth topping up 100 mm of loft insulation?

Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.
