Roof Insulation Compton

Honest advice

How to Tell You Need Roof Insulation

Insulation upgrades cut heating bills and improve the EPC, but the right approach depends on how you use the loft. Here is what to consider on a Compton property. On Compton properties, compton is a small downland village of period and modern homes on lanes where scaffold access needs planning but pavements are rarely an issue.

A cold house with a loft you rarely enter
Under 270mm of insulation at joist level
A loft conversion needing warm-roof insulation
Condensation or damp in a poorly ventilated loft

When it is not the answer: Adding insulation without ensuring loft ventilation can cause condensation — we assess airflow first and will not over-insulate a poorly ventilated void. Read the full guide.

Customer Reviews

What Customers Say

★★★★★

"Combined the insulation top-up with the re-roof. Scaffold was already up so the cost was minimal. EPC improved from E to D in one job."

Richard F. · Badger Farm, Winchester

★★★★★

"Clear explanation of the correct depth and why our existing 100mm was inadequate. Job done in a day and the house is noticeably warmer."

Janet H. · Harestock, Winchester

★★★★★

"Added the loft insulation at the same time as the fascia replacement. Sensible use of the access — would have cost three times as much as a separate job."

Simon K. · Eastleigh, Hampshire

Our Process in Compton

How Roof Insulation Works in Compton

Upgrading from 100mm to 270mm improves EPC rating by 1–2 bands and reduces heating bills by an estimated £150–£250/year. Most cost-effective when combined with a re-roof while scaffold is in place. In Compton, the highest chalk escarpment wind exposure in coverage area means roof insulation specifications are applied with an understanding of the Victorian farmhouse and modern infill housing stock.

1.Survey confirms existing depth, insulation type and ventilation condition
2.Confirm cold or warm roof specification
3.Install 100mm mineral wool between joists (or confirm existing is sound)
4.Install 170mm mineral wool across joists at 90 degrees
5.Fit insulated draught-proof loft hatch cover
6.Confirm eaves ventilation paths are not blocked by new insulation

Timescales

How Long Does It Take?

Job	Typical duration
Joist-level top-up	Half a day
Full loft insulation	1 day
Warm-roof (rafter) insulation	2–3 days

Insulation is internal work and largely weather-independent. In Compton we confirm the likely duration on the survey, once we have seen the access and the roof.

Access

Getting Safely onto Compton Roofs

Loft-level insulation needs no external access; warm-roof work is done while the roof covering is off. Scaffold is specified for: only warm-roof insulation carried out as part of a re-roof - always itemised in your written quote, never a hidden extra, and we arrange it.

Compton is a small downland village of period and modern homes on lanes where scaffold access needs planning but pavements are rarely an issue. Pavement scaffold and skip permits go through Winchester City Council; allow a few working days on streets like Place Lane, Compton Street where space is tight.

Good to know

Disruption, Mess & Weather in Compton

Loft-level work needs internal access to the loft hatch for a few hours; warm-roof work is external. You do not need to stay home for external work — just power and access agreed in advance.

Best done alongside a re-roof so the rafter line can be upgraded while the covering is off — disruption-free and cost-effective. Exposed chalk-down position brings wind exposure on ridges and verges.

FAQ

Roof Insulation Compton — Questions

Loft insulation top-up from 100mm to 270mm on a standard Compton semi: £300–£500. This is the most cost-effective EPC improvement available and is best carried out while scaffold is in place for any re-roof work.

The current UK minimum for cold roof insulation is 270mm — 100mm between joists and 170mm across. Many Compton Victorian farmhouse and infill properties have only the 100mm installed in the 1980s–90s Government programmes. Top-up is straightforward and significantly improves the EPC rating.

Yes — insulation top-up while scaffold is in place for a Compton re-roof costs significantly less than a separate mobilisation. We include insulation top-up as an add-on option in all Compton re-roof quotes where the existing depth is below 270mm.

Cold roof construction requires ventilation above the insulation layer. Breathable underlay (which we install on all Compton re-roofs) eliminates the need for a separate ventilation path. Old bitumen felt requires ventilation paths that must not be blocked by insulation.

Upgrading from 100mm to 270mm typically improves EPC rating by 1–2 bands. In Compton's property market, an EPC rating improvement from D to C adds measurable value. Insulation is the most cost-effective route to EPC improvement on most Compton Victorian farmhouse and infill properties.

The Energy Company Obligation (ECO) scheme may fund insulation for Compton homeowners on qualifying benefits or with a low EPC rating. Local authority referrals are available. Privately-funded insulation top-up is available for all Compton properties — most cost-effective when combined with re-roofing.

Mineral wool (glass or rock wool) is the standard specification for Compton loft top-ups. It is non-combustible, has zero ozone depleting potential, and performs correctly at the depths required. PIR board is used for warm roof flat roof applications.

No — cold roof loft insulation is installed at ceiling joist level, below the roof deck. The roofing work above is entirely separate. The only interaction is the ventilation specification — which we confirm at survey for each Compton property.

Yes — loft insulation top-up can be carried out independently of any roofing work on most Compton properties with accessible lofts. We survey the loft access, existing insulation depth and ventilation condition before confirming specification.

Upgrading from 100mm to 270mm on a Compton semi: estimated annual saving £150–£250 on heating bills. At an installation cost of £300–£500, the payback period is typically 1.5–3 years. With an EPC improvement, the property value benefit typically exceeds the installation cost on day one.
