Loft insulation in Highgate
If your Highgate loft has 100mm of flattened wool and a boarded patch balanced on the joists, you are not alone and you are losing money every winter. We fit insulation to the recommended 270mm depth, and raise any boarding clear so it keeps working.

Highgate's homes
The character of Highgate roofs
Highgate is a good illustration of how North London was built. The stock here runs to Victorian and Edwardian terraces, generous interwar semis and a scattering of post-war infill, and the roofs are predominantly steeply pitched slate and clay tile roofs with usable, walkable voids above the top floor. Within a single street you can find a loft you can stand up and walk around in, and one three doors along where the only sensible approach is to work on your knees.
That variation is exactly why we survey before quoting. Two lofts of identical floor area can differ by a substantial margin in price because one has 150mm joists and a wide hatch, and the other has shallow, irregular timbers, a 400mm opening and a cold water tank sitting in the middle of the run.
Locally, 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 — worth knowing before you compare quotes.

Five ways we keep Highgate 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 depthMineral wool cross-laid to the 270mm depth current regulations recommend. For most Highgate homes this is the single highest-value thing you can do to the building.
Loft boarding
Storage-readyTongue-and-groove panels, screwed rather than nailed so they lift again if a cable needs reaching — raised clear of the insulation throughout.
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 Highgate 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
Highgate loft insulation — common questions
How much does loft insulation cost in Highgate?
We price Highgate jobs after a free survey, itemised so you can see what the insulation, any boarding and any removal each cost. There is no call-out charge and the figure does not move once it is written. The London cost guide explains what drives it.
What insulation depth do you fit?
The recommended 270mm, achieved in two layers: the first between the joists, the second laid across them to eliminate the cold bridge through the timber. Skipping that second cross-lay is one of the most common shortcuts in the trade.
Will this improve my EPC rating?
It is one of the most reliable ways to improve a rating, because depth is a direct input rather than an inferred assumption. How far it moves depends on everything else about the Highgate property, but the direction is not in doubt.
