West London loft specialists
Kensington sits in West London, where the housing is dominated by Victorian terraces, large Edwardian villas, extensive interwar suburban development and post-war blocks. Much of it was insulated to a standard that has since been superseded twice over. We put that right — properly, in a day, for a price agreed in advance.

Why it matters
For a Kensington 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practical upshot is simple — the loft is the first upgrade worth making and the one most likely to have been done to an outdated standard.
Kensington's homes
Kensington is a good illustration of how West London was built. The stock here runs to Victorian terraces, large Edwardian villas, extensive interwar suburban development and post-war blocks, and the roofs are predominantly pitched tile and slate roofs, with hipped ends common on the suburban stock. 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, the 1930s suburban expansion here produced thousands of near-identical semis, which means the same loft problems repeat street after street — worth knowing before you compare quotes.
Our services in Kensington
Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.

A/A+ fire rated and around 40mm thick. For Kensington properties where deepening the rafters is impractical, this is what makes the numbers work.

Mineral wool cross-laid to the 270mm depth current regulations recommend. For most Kensington homes this is the single highest-value thing you can do to the building.

Storage that does not flatten your insulation. We raise the deck on battens so the full depth survives underneath — the version most Kensington lofts should have had first time.

Fixed, stable access instead of a stepladder on the landing. Timber, aluminium or concertina, chosen to suit the space your Kensington home actually has.

The whole loft dealt with at once, for one fixed price. Most Kensington properties are finished within a day.
Describe the property and what is bothering you about it, and we will recommend the right combination — or tell you that nothing needs doing.
Where we work

Questions & answers
None of the work we do requires planning permission. If your Kensington property is listed or in a conservation area, that affects the roof covering and external alterations rather than insulation laid inside the roof space, though it is always worth mentioning at survey.
Free, with no call-out fee and no pressure. A meaningful proportion of our Kensington surveys conclude that the loft is already adequately insulated and the homeowner should keep their money — which is a perfectly normal outcome.
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 Kensington property, but the direction is not in doubt.
We fit ladders alongside insulation and boarding routinely — it is one of the main reasons the combined makeover works out cheaper than booking the elements separately.
