Overview

## What Raised Boarding Systems actually involves

What it is

Installation of structural raised legs that lift a boarded floor 220mm above the existing ceiling joists, leaving room for a full 270mm of insulation underneath plus a 50mm air gap.

Who it's for

Anyone planning loft boarding alongside insulation work. Anyone who has already insulated to 270mm and discovered they can't walk on it. Homes targeting an EPC band C or higher for re-mortgaging or rental compliance.

When you need it

Always; there is no scenario where boarding directly to joists outperforms a raised system. The cost difference is £150–£300 on a typical job, recovered within 18 months of insulation savings.

Why it matters

Building Regs Part L1B (2022) effectively requires 270mm of insulation. Direct boarding crushes this to 100mm, halving thermal performance and breaching current standards. Raised systems are now the only compliant option.

The Real Cost of Ignoring This

## Why Direct-to-Joist Boarding Is a False Economy

Saving £200 by boarding directly to joists is a textbook false economy. Here's the actual maths.

### What it costs to ignore

- Insulation crushed to 100mm loses 60% of its thermal performance, adding £180–£320/year to bills.
- Building Regs non-compliance flagged on home surveys, direct hit to resale value.
- Trapped moisture between boards and crushed insulation rots ceiling joists within 5–7 years.
- EPC rating drops a band, typically £4,000–£8,000 off resale value of a 3-bed semi.
- Re-doing the job correctly later costs roughly 3× the original: boards must be lifted, insulation replaced, sub-frame fitted from scratch.

### Common mistakes we fix

- Choosing direct boarding to save £200, losing £900 of EPC value.
- Using DIY plastic stilts (not BBA-certified) that compress under load and creak.
- Installing raised legs without correct centres: boards bow underfoot.
- Skipping the air gap above insulation, defeating the purpose of the raised system.

Our Process

## The 5-step raised boarding systems system

1. 01
   ### Survey & Plan
   Existing insulation depth, joist span and storage zones mapped. Fixed written quote after the in-loft survey.
2. 02
   ### Insulation Top-Up (If Required)
   We bring insulation up to 270mm before raising the floor, combined-job pricing saves a separate trip later.
3. 03
   ### Raised Leg Install
   BBA-certified raised legs fitted at 400mm centres, levelled across the loft span.
4. 04
   ### Decking & Edging
   18mm P5 moisture-resistant T&G boards screwed to legs, perimeter eaves protected, downlight covers fitted.
5. 05
   ### Sign-Off
   Walk-test, tidy handover and 10-year workmanship guarantee.

Why It's Worth It

## The measurable benefits

### Full 270mm Insulation Preserved

EPC stays intact, heating bills stay down, building regs stay satisfied.

### Building Regs Compliant

Part L1B compliant install, passes any home survey, mortgage valuation or rental inspection.

### 100kg/m² Load Rating

Engineered for real storage, suitcases, business stock, Christmas decorations, gym kit.

### Cold-Roof Airflow Maintained

50mm air gap above insulation prevents condensation and protects roof timber.

### Future-Proof

If insulation regs tighten further, your raised system already has headroom built in.

### Same-Day Install

Most 20m² installs completed in a single day, including insulation top-up.

In Depth

## Raised Boarding Systems, the technical detail

Raised boarding systems sound technical, the principle is dead simple. Lift the floor above the insulation. The detail of how that's done is what separates a 25-year floor from a 5-year creaking disappointment.

### BBA-Certified Raised Systems

We use BBA-certified raised loft systems whose certification covers structural loading, insulation compatibility and fire performance, accepted by all major home surveyors and mortgage lenders.

### Leg Spacing & Centres

Legs at 400mm centres on standard 4×2 joists give a 100kg/m² distributed load with zero deflection. Wider centres (600mm) are only acceptable on heavier 6×2 joists with C24 grading.

### P5 Moisture-Resistant Decking

We only deck with 18mm P5 chipboard, never standard P2. P5 carries a 25-year structural rating in intermittent damp environments and won't swell at the joints.

### Edge Detail & Eaves Protection

We never deck right to the eaves, leaving a 200mm clear band protects ventilation airflow. The deck edge is finished with a softwood lipping for clean visual edges.

### Combining With Existing Insulation

If existing insulation is dry and uncompressed, we install over it. If it's wet, settled or contaminated, we top-up or replace before the raised system goes in, quoted transparently.

### Listed & Period Properties

Period properties with shallow joists (around 100×38mm) may need joist reinforcement before any raised system. We assess and quote any structural prep at the survey stage.
