Home insulation — every method we fit, and the one we recommend

Mineral wool. Cavity beads. Multifoil. We fit every type — but we recommend multifoil on most homes we survey. The 20th-century materials leak heat, compact over time, and use formaldehyde binders. Multifoil doesn't.

About this service

Insulation, designed properly.

If your bedrooms still feel cold by January and the radiators are working overtime, the insulation in your walls and loft is almost certainly thinner than it should be — most UK homes built before 1990 are leaking 30–40% of the heat they pay for. We fit every type of insulation: rock wool and mineral fibre in lofts and cavities, EPS bead in masonry cavities, sheep wool and natural fibre for breathable old fabric, and our recommended premium method — multifoil — wherever performance matters most. Multifoil is thinner than conventional fibre, delivers far higher thermal performance per millimetre, and handles the moisture profile of older UK fabric without trapping vapour where it shouldn't go. **For most homes we survey, we recommend multifoil** — see our dedicated Multi-Foil Insulation service page for the technical detail and the case studies. Loft top-up, cavity wall fill, internal wall insulation, underfloor — we fit them where they're the right tool for the job, and we say so honestly when they're not. PAS2030-accredited surveyor walks every room, gets into the loft, quotes to the nearest £10, and installs in a single visit wherever possible. Dust sheets down. Vacuum up behind us. Photos at every stage. Most jobs come back with grants attached and we handle the paperwork end-to-end. 25-year product guarantee, 5-year workmanship, insurer-backed.

How it works

How it works, step by step.

  1. 01

    Free home survey

    A qualified surveyor spends 45–60 minutes at your home — loft, walls, ventilation, EPC check. No obligation, no pressure.

  2. 02

    Transparent fixed quote

    Written plan within 48 hours. Every option priced line-by-line, with the payback period for each.

  3. 03

    Single-day install (lead installer named on day one)

    Our own PAS2030-accredited team of two — never subcontracted, lead installer is your single point of contact. Dust sheets down before we start. Vacuum up before we leave. Photos of every stage on a shared album you keep. Most jobs done in a single visit, before the kettle's gone cold a fourth time.

  4. 04

    Certification + guarantees

    TrustMark-lodged certificate, 25-year product guarantee and 5-year workmanship guarantee issued within 7 days.

A real install

A loft, before and after.

Neglected loft with patchy decayed mineral wool, exposed felt, cobwebs and debris between roof timbers.
Same loft after retrofit — fresh blond mineral wool laid evenly between joists with a central walkway.
BeforeAfter

Same loft. Same skylight. One day of work. The roof is roughly a quarter of a home's heat loss — fully fitted, that quarter stops escaping.

Accreditations that matter

Not logos. The certifications that matter for Insulation.

Every one of these is checkable online. Every one changes something concrete about the job — the survey, the materials, the guarantees, the way the grants land.

  • PAS 2030

    Install quality standard for retrofit measures

    Our teams are certified to the installation standard that grant-funded work is audited against.

  • TrustMark

    The only endorsement scheme backed by the UK consumer body

    Every install is lodged on the TrustMark register so your cover travels with the property.

  • BBA certified

    British Board of Agrément product certification

    Every insulation layer we install is named on the quote and BBA-certified — no unlisted substitutes.

  • CIGA / SWIGA

    25-year insurance-backed cavity + solid-wall guarantee

    If OMEGA is no longer trading in 2049, your guarantee still pays out. Insurance-backed, not hope-backed.

Dataset
142 OMEGA insulation installs in Q1 2026, measured before and after with thermal camera + air-tightness fan test.
Period
Jan 2026 – Mar 2026.
How we calculate it
Pre-install heat-loss vs. post-install heat-loss, multiplied by the Ofgem default tariff for the heating fuel. £425 is the mean year-one saving across the fleet.
What this excludes
  • Excludes top-ups under 100mm (insufficient delta to measure reliably).
  • Excludes commercial properties.

The OMEGA recommendation

Pair your insulation with multifoil for the highest thermal performance per millimetre.

Conventional insulation is great where you've got the depth. Multifoil wins where head height, build-up depth, or wall thickness are tight — and it stacks WITH conventional upgrades, not instead of them. Most homes we survey end up with both.

Insulation — alone

~22% heat-loss cut

Insulation + Multi-Foil Insulation

Annual saving
£640/yr
Payback

~35% heat-loss cut

Why pairing wins

  • Multifoil sits where conventional insulation runs out of room — rafters, room-in-roof, internal stud walls — without losing internal floor area.
  • A 30–45mm multifoil layer adds U-value performance equivalent to 100–150mm of mineral wool, on the SAME job, in the SAME visit.
  • ECO4 grants stack across both measures when eligibility lines up — single survey, single application, single install crew.

The OMEGA Comfort Promise

A measurable drop in heat-loss within 30 days — or we redesign at our cost.

Before we install, we measure your home with a thermal camera and an air-tightness fan test. After we install, we re-measure. We promise a minimum 25% measured heat-loss reduction across the surveyed surfaces — written into your quote, signed by your surveyor, refundable if missed.

If we miss

If the post-install measurement misses our 25% target, we redesign and remediate at our cost. No top-up invoice. No excuse.

Honest about who this isn't for

This isn't right for new-build homes (post-2010 already meet the standard) or for properties with active rising damp — we'd recommend fixing the damp first and the insulation will follow.

Loft & insulation add-ons

Worth adding to your install (or your existing setup).

Pricing is indicative — we re-quote against your actual loft on the survey. Bundle pricing if you take more than one (and most homes do).

  • Capacity

    Most-asked add-on

    Loft boarding + folding access ladder

    Turns an insulated loft into usable storage without compressing the insulation (raised on stilts above the joists). Single most-asked add-on across our insulation jobs.

    From £449One-off
  • Maintenance

    Rodent-proof eaves seal

    Stainless mesh sealed into every eaves entry point. Voiding the workmanship guarantee through rodent damage is the #1 claim category — this prevents it.

    £189One-off
  • Performance

    Smart humidity monitor (Wi-Fi)

    Wireless sensor in the loft, app on your phone. Catches condensation behind insulation early — the difference between a callback and a £4,000 black-mould remediation.

    £99 fittedOne-off
  • Comfort

    Pipework + tank lagging upgrade

    Cold-water tank, hot-water tank, and feed pipes properly lagged. Completes the thermal envelope — without it, your insulated loft cools the pipes faster than it warms the rooms.

    £129One-off
  • Comfort

    Acoustic upgrade pack

    Extra mineral-wool layer above the thermal layer. Drops bedroom noise from rain and traffic noticeably — pairs with the insulation install at a fraction of the cost done separately.

    £249 per storeyAdd-on at install
  • Performance

    EPC re-issue + lodgement

    After insulation, your EPC band typically lifts a tier. We get it re-assessed and lodged — adds value if you sell, helps any future grant application that's EPC-gated.

Grants and funding

The grants you can get.

Eligibility changes often, the schemes don’t reward homeowners who fill the forms in themselves, and the paperwork is genuinely tedious. So we file it for you.

We handle the paperwork end-to-end

  • ECO4 + GBIS — insulation, paid direct to us
  • BUS — up to £7,500 off heat pumps
  • SEG — export tariff registration
  • OZEV / EVHS — EV charger grants

You sign once. We submit, evidence, and chase. The grant comes off your final invoice — nothing for you to claim back.

  • ECO4 funding (eligibility-led, up to 100% of install)

  • Home Upgrade Grant 2 — off-gas-grid homes

Common questions

Common questions, answered honestly.

  • Will I qualify for grants and funding?

    Most homes rated EPC D or below qualify for at least one of the available schemes. Our surveyor checks eligibility against ECO4 and HUG2 in the same visit — if you qualify, we handle the paperwork.

  • How disruptive is the installation?

    Loft and cavity work is normally a single-day job with zero disruption to your kitchen or bathroom — we put dust sheets down, vacuum up behind us, and you stay in the home throughout. Internal wall insulation takes 2–3 days per room, and we work room-by-room so you're never living out of one bedroom waiting for the rest. Your surveyor maps the order on the day so you know exactly when each room is sealed, plastered and back to normal.

  • What is the difference between internal and external wall insulation?

    External wall insulation (EWI) wraps the outside of your home in rigid insulation and a render or board finish — best for solid-wall houses where you want to keep every inch of room size and lift the kerb appeal at the same time. Internal wall insulation (IWI) is faster and cheaper but takes around 60mm off each external-facing room. Your surveyor will recommend the right one based on your property type, planning constraints (some conservation areas only allow IWI), and your funding route — fully written into the fixed-price quote before you sign.

  • Does insulation cause damp?

    Only if it's installed badly — and that's the difference between a PAS2030 install and a back-of-the-van one. Insulation traps heat that used to escape, which means moist indoor air condenses on whatever stays cold; that's why ventilation matters as much as the insulation itself. Every OMEGA install includes a free ventilation assessment, with extract fans or trickle vents upgraded where needed at no extra charge. We back the work with a 5-year guarantee against condensation damage.
