Loft hatches and insulation in Bromley

We fit insulated loft hatches, enlarge awkward hatches, and top up insulation before boarding, so your loft stays warm, accessible and usable. We cover Bromley, Orpington, Beckenham and nearby.

What is included

• Insulated and draught-sealed hatches
• Hatch enlarging or moving, with joists properly trimmed
• Insulation top-up before boarding
• Loft lights fitted by a qualified electrician (ask at survey)

Why the hatch matters

An old, uninsulated hatch that does not seal well can let warm, moist air into the loft. An insulated, draught-sealed hatch helps keep heat in the house and reduces moisture reaching the loft. If you also want a ladder, many hatches come as a combined unit; see loft ladder fitting.

Enlarging or moving a hatch

A larger hatch makes it easier to get boxes, cases and a ladder through. Enlarging one usually means cutting a ceiling joist and adding trimmers to carry the load around the opening. Trussed rafters must not be cut without a structural engineer's advice. We check the roof structure at the survey and explain what is possible. Our loft hatch replacement guide has more detail.

Topping up insulation first

The Energy Saving Trust recommends a minimum of 270mm of loft insulation, and advises not to squash mineral wool, as that reduces how well it insulates. It also advises leaving a small ventilation gap between the insulation and the boards to help prevent condensation. If your loft has less than that, the best time to top it up is before any boards go down. Where boarding is planned over deep insulation, we use raised loft boarding to keep it uncompressed. See loft insulation top-up.

Ventilation and condensation

As insulation levels go up, the loft gets colder, so ventilation becomes more important. We keep eaves ventilation clear and leave the gap above the insulation open. If we see signs of condensation or damp at the survey, we point them out.

Lighting

A light makes a loft much safer to use, especially when you are stepping off a ladder or reaching for boxes near the eaves. New lighting should be installed by a qualified electrician, so ask us at the survey and we will explain the options.

Water tanks and pipes

When insulation is topped up, the area directly under a cold water tank is usually left uninsulated so warmth from below helps protect it from frost, and the tank and pipes are insulated instead. We keep walkways to the tank so it stays reachable.

For the whole picture, see loft boarding and our cost guide.

Common questions

Is an insulated loft hatch worth it?

An uninsulated hatch can let heat and moisture escape into the loft. An insulated, draught-sealed hatch helps reduce both.

Can you make my loft hatch bigger?

Usually, yes. It may involve trimming a ceiling joist. Trussed rafters need a structural engineer's advice before any cutting.

How deep should loft insulation be?

The Energy Saving Trust recommends a minimum of 270mm. We check your current depth at the survey.
