    Quote turnaround

    Written, fixed-price, line-by-line. No pressure, no chasing

The surveyor spent an hour walking us through the whole house, wrote a plan at the kitchen table, and the grant side of it was sorted by them, not by me. Five months in, the bills are down by almost exactly what they said.

    The OMEGA difference

    Eight things we do that most home installers don't.

    Not brand chest-beating. Each of these is something you can phone up and check — written down on every quote, baked into every install.

    OMEGA
    A typical installer

    • Who turns up on install day

      Our own PAS2030-accredited engineers, directly employed

      Subcontracted day-labour, often met for the first time that morning

    • How the quote is built

      Written line-by-line inside 48 hours, each measure costed and justified

      Pressure-priced on the day with artificial "sign now" discounts

    • Grant and funding paperwork

      ECO4 · GBIS · BUS · HUG2 checked on the first visit, filed by our team

      You chase the forms, or pay full price because nobody looked

    • Survey depth

      Room-by-room heat-loss calc, ventilation check, thermal imaging where it helps

      A 15-minute look round and a best-guess sizing from the EPC

    • Product spec

      BBA-certified materials named on the quote — the installer signs each layer off

      "Generic equivalent" materials chosen for margin, not performance

    • Guarantees you can actually claim on

      25-year insurance-backed product cover plus our own 5-year workmanship guarantee

      1-year workmanship only, manufacturer cover voided by install errors

    • Aftercare once the van drives off

      Same office you called first day. Issues phoned in and fixed, not forwarded

      A different number every time, with "that is out of warranty" as the default reply

    • Honesty when a measure isn't right for your home

      We'll tell you to insulate first, or wait a year — and quote that instead

      Sells the measure that pays the commission, regardless of fit

    Ask any OMEGA surveyor to walk through this list at your first visit — if we don't match every row, don't hire us.

    Accreditations that matter

    Not logos. The certifications home actually needs.

    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.

    • 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.

    • PAS 2030

      Install quality standard for retrofit measures

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

    • MCS

      Microgeneration Certification — solar, heat pumps, batteries

      Without MCS you can't claim the Smart Export Guarantee, the BUS grant, or 0% VAT. We're fully certified.

    • BBA certified

      British Board of Agrément product certification

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

    How it works

    Four steps from survey to handover.

    1. 01

      Whole-Home Energy Survey

      We assess every element of your home — loft, walls, floors, windows — and identify all insulation opportunities.

    2. 02

      Comprehensive Grant Check

      We check ECO4, GBIS, BUS, and any local authority funding to maximise the free measures available to you.

    3. 03

      Phased Installation

      We install each measure in the right order, minimising disruption and ensuring each element works with the others.

    4. 04

      Final Inspection & EPC

      After all measures are installed, we arrange a new EPC to document the improvement in your home's energy rating.

    What most customers ask first

    The honest worries about home — named and handled.

    Every homeowner brings two or three silent worries to the first survey. Here's what they are and how we handle them — no salesy dodges.

    • The worry

      Is this going to feel like a sales pitch?

      How we handle it

      No. The survey is a 45-minute look round with a written plan at the end — we leave without asking you to sign anything. Nearly a third of our surveyed customers go with us later, not the same day.

    • The worry

      What if I don't qualify for the grants?

      How we handle it

      You still get the same fixed-price, line-by-line quote and the same 25-year product cover. We publish the self-funded payback next to the funded one so you know either number before you commit.

    • The worry

      How disruptive is the install?

      How we handle it

      Most of our measures are single-day from outside or from one room at a time. Dust sheets down, vacuumed up behind us, photos of every stage. You can work from home through nearly all of it.

    • The worry

      What if something goes wrong later?

      How we handle it

      One phone number — 0800 229 4094 — and the same team comes back out. 25-year product guarantee, 5-year workmanship cover. If it breaks, we fix it free. That's the deal.

    Live · grant eligibility check

    What grants are likely on your home?

    Type your postcode. We'll show which schemes are likely to apply for your property and this measure. The exact eligibility check happens on your free survey — this is the indicator that gets you 80% of the way there.

    Heuristic indicator only — the survey is where actual eligibility is decided. Free, no obligation, takes 45 minutes.

    Common questions

    Home — answered honestly.

    What does a whole-home insulation service include?

    We assess and install loft insulation, cavity wall insulation, external wall insulation, underfloor insulation, and draught-proofing as needed. Every home is different, so we tailor the approach to your property.

    Is it better to do everything at once?

    Often, yes. Combining measures in a single project is more cost-effective, qualifies for more grant funding, and delivers the biggest energy saving. But we can phase the work if that suits you better.

    Where we install

    Home across Essex, Suffolk, Kent and Cambridgeshire.

    We install home in every one of our covered counties. Each local team knows the housing stock, the grant routes, and the council-specific flex schemes that apply.
