SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Brentwood loft has already been converted, insulation has to follow the rafters rather than the floor. SuperQuilt does that in 40mm instead of the 200mm-plus a wool build-up would need.

Loft insulation in Brentwood
Our installers work in Brentwood and across the wider Essex area every week, which means we know what is behind the hatch before we open it. That familiarity is why our quotes hold and why the job usually takes a day rather than three.

Put against current energy prices, a Brentwood loft still carrying 100mm of settled wool is costing its owner money every single winter it stays that way.
Brentwood's homes
Why Brentwood lofts need attention
Brentwood forms part of Essex, an area whose housing is characterised by interwar and post-war suburban development, older town centres and a large amount of modern estate housing. The bulk of it went up during the 1920s onwards, decades before insulation was a design consideration at all, and what sits above the ceilings today is usually a retrofit added at some point in the last fifty years to whatever standard was current at the time.
That matters because the standard has moved repeatedly. Lofts insulated in the 1980s typically received 100mm; earlier work was often 50mm or nothing. Current guidance is 270mm. A great many Brentwood houses therefore contain insulation that was entirely adequate when it was fitted and is now doing roughly a third of the work it should be — while the homeowner reasonably assumes the loft is 'done'.
The postwar and modern stock generally has adequate original insulation for its era, which is now well below current recommended depth. It is the sort of thing a survey establishes in ten minutes and a phone quote never can.

Five ways we keep Brentwood 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 Brentwood loft actually performs.
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 dayFitted 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-oneThe whole loft dealt with at once, for one fixed price. Most Brentwood properties are finished within a day.

Questions & answers
Brentwood loft insulation — common questions
How long does the work take in a typical Brentwood home?
Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Brentwood lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.
Will insulating my loft cause damp?
Not if it is done properly. Insulating the floor makes the roof space colder, so moisture condenses more readily — the defence is the ventilation path at the eaves. Blocking it with insulation is what creates damp lofts. We keep it clear on every job. Our ventilation guide explains the mechanism.
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.
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.
Do you work in the streets around Brentwood?
We do. Coverage extends across Brentwood and the neighbouring areas, and we are happy to confirm your specific postcode over the phone before booking anything.
Do I need planning permission in Brentwood?
Not for insulation, boarding or a ladder. The line falls at conversion — turning the loft into a habitable room — which is a structural job requiring building control sign-off and a different trade entirely.
