Top tips
Hiring a loft ladders, without the regret.
Four moves that separate a smooth job from a nightmare.
Get the right type for your hatch.
Folding (3-section), concertina, sliding, electric — each fits different hatch sizes and ceiling heights. Measure both before ordering.
Insulated hatch is the standard now.
Uninsulated hatches lose 5–8% of household heat. Building Regs Part L push for insulated hatches on all installs.
Boarding the loft is a separate job.
Most loft ladder installers don't board the loft. Get the boarding quote separately — or with the same firm if they offer both.
Don't crush the insulation.
Standard loft boarding compresses insulation to 50% effectiveness. LoftZone or raised boarding systems keep insulation full depth — essential post-2022 Building Regs.
