Northumberland Park's homes
Why Northumberland Park houses lose more heat than they should
Most of Northumberland Park was built during the 1870s through the 1930s, and its roofs are typically steeply pitched slate and clay tile roofs with usable, walkable voids above the top floor. 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 many of the larger houses were divided into flats decades ago, so the loft often sits above a top-floor conversion with its own separate access.

Five ways we keep Northumberland Park homes warm
Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.
Loft insulation installation
270mm depthFull-depth mineral wool, fitted with the ventilation path protected and the hatch sealed — the details that decide whether a Northumberland Park loft actually performs.
Loft boarding
Storage-readyA squared, edged deck reached from the hatch, with the eaves left open so the roof keeps breathing. Sized to what you will actually use rather than the whole Northumberland Park footprint.
Loft ladders
Fitted in a dayFixed, stable access instead of a stepladder on the landing. Timber, aluminium or concertina, chosen to suit the space your Northumberland Park home actually has.
Loft makeovers
All-in-oneInsulation, boarding, lighting and a ladder handled together in one visit — cheaper and better sequenced than buying the four separately.

Questions & answers
Northumberland Park loft insulation — common questions
Can I still use my Northumberland Park loft for storage afterwards?
Absolutely. The only wrong way to do it is to board flat onto the joists. We raise the deck on battens or loft legs, board it in tongue-and-groove panels and leave the eaves clear so the roof keeps ventilating.
Do you offer free surveys in Northumberland Park?
Always, and there is no charge or obligation attached. A survey takes around half an hour. We would rather spend it establishing what your Northumberland Park loft actually needs than quote blind and revise the price later.
Do you remove the old insulation?
Only when it needs to go. Sound, dry wool can be topped over, which saves you the removal cost. Material that is damp, vermin-fouled or collapsed does come out, and we bag it and take it away. Which applies to your Northumberland Park loft is established at survey and priced separately.
Do you work in the streets around Northumberland Park?
Yes. Northumberland Park is well within our regular working area, along with everywhere immediately around it — see the full list of areas.
Can you fit a loft ladder at the same time?
Certainly. Doing the ladder in the same visit means the boarding is planned around where the ladder lands, which is considerably better than retrofitting one to a deck that was not designed for it.
How long does the work take in a typical Northumberland Park home?
Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Northumberland Park lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.
