What is different about insulating a flat's loft?

In most leasehold flats the loft belongs to the freeholder, so the managing agent or freeholder must agree to the work. We can quote for a single flat or the whole block, and work to the managing agent's access and insurance requirements. More about loft insulation for a flat.

Questions about loft insulation for a flat in Harrow

Do you charge extra to travel to Harrow?

Not normally. Our guide prices include normal travel to Harrow. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Is loft work in Harrow different from anywhere else?

The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

What do I need to do before you arrive in Harrow?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Can I insulate the loft above my flat?

Usually yes, with the freeholder's consent. The lease will say who owns and maintains the roof space.

Who pays for loft insulation in a block of flats?

If the loft is common parts, the freeholder usually arranges it and recovers the cost through the service charge, according to the lease.
