Loft insulation in Greenwich

Whether you are in a period terrace, an interwar semi or something considerably more recent, we specify insulation for the roof it is actually going into. Greenwich homes get a free survey, a fixed price and work carried out to current recommended standards.

Why it matters

The case for insulating your Greenwich loft

25%of a home's heat is lost through an uninsulated roof

For a Greenwich homeowner the practical upshot is simple — the loft is the first upgrade worth making and the one most likely to have been done to an outdated standard.

Greenwich's homes

Why Greenwich houses lose more heat than they should

Most of Greenwich was built during the 1880s through the 1930s, and its roofs are typically pitched tile and slate roofs with reasonable head height, and hipped ends on the interwar semis that reduce the usable void. Nothing about that construction is defective — these are, for the most part, sound, well-built houses. They were simply designed for a world where heating was cheap and thermal performance was not something anyone measured.

Bolting modern expectations onto that fabric is largely a matter of doing a few things properly rather than doing many things at all. Full-depth insulation at ceiling level, a ventilation path that has not been blocked, a hatch that is sealed rather than left as a hole, and boarding that sits above the wool instead of on top of it. Get those four right and the loft stops being the weak point.

Bear in mind too that hipped roofs on 1930s semis cut the usable loft area down sharply at the corners, which changes how much of it is worth boarding.

Five ways we keep Greenwich homes warm

Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.

At roughly 40mm, multifoil delivers serious performance without stealing headroom — which is why it is the answer for Greenwich homes with a room in the roof or a sloping ceiling.

Topping up from the 100mm many Greenwich houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.

Loft boarding

Storage-ready

Tongue-and-groove panels, screwed rather than nailed so they lift again if a cable needs reaching — raised clear of the insulation throughout.

Fitted in a day

Fitted in a day, finished to match your landing, with the hatch insulated and draught-sealed as part of the same job.

Loft makeovers

All-in-one

Insulation, boarding, lighting and a ladder handled together in one visit — cheaper and better sequenced than buying the four separately.

Questions & answers

Greenwich loft insulation — common questions

How long does the work take in a typical Greenwich home?

Most Greenwich lofts are insulated to full depth in half a day. Adding raised boarding takes it to a full day, and fitting a ladder at the same time adds a couple of hours. We give you the expected duration with the quote, not on the morning.

Do you offer free surveys in Greenwich?

Free, with no call-out fee and no pressure. A meaningful proportion of our Greenwich surveys conclude that the loft is already adequately insulated and the homeowner should keep their money — which is a perfectly normal outcome.

Do you work in the streets around Greenwich?

Yes. Greenwich is well within our regular working area, along with everywhere immediately around it — see the full list of areas.
