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.

About this service

Heat pumps, designed properly.

A heat pump is the single biggest step you can take to get off volatile gas prices — but only when it's designed properly. Done well, it delivers the same warmth as your gas boiler for roughly a third of the fuel. Done badly, it runs hot-and-cold and costs more than the gas it replaced. The difference is survey, sizing and weather-compensation setup — the detail most installers treat as an afterthought. We do the room-by-room heat-loss calc in-house, specify radiators honestly, and commission the control strategy properly before handing over. The £7,500 Boiler Upgrade Scheme grant is handled end-to-end by our team.

What you get

  • Delivers 3 kWh of heat for every 1 kWh of electricity used — 300%+ efficient at sensible flow temperatures
  • £7,500 off the install via the Boiler Upgrade Scheme — we manage the full application and paperwork
  • Designed to MCS MIS 3005 with a proper room-by-room heat-loss survey — not a quick guess from the EPC
  • Seven-year manufacturer warranty and five-year workmanship cover — whichever calls first, we come out
  • Works with your existing radiators in most well-insulated homes; upgrades only where the maths says so

The OMEGA difference

Eight things we do that most heat pumps 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 heat pumps 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.

  • 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.

  • MCS MIS 3005

    Heat pump design standard

    Every heat pump design is sized to a full room-by-room heat-loss calc, not a back-of-envelope guess from the EPC.

  • Gas Safe

    Legal requirement for anyone working on domestic gas

    Every boiler fitter on our team is on the Gas Safe register — checkable in 30 seconds online.

  • 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.

How it works

Four steps from survey to handover.

  1. 01

    Free Home Energy Survey

    We assess your home's heat loss, existing radiators, and hot water requirements to design the right system.

  2. 02

    BUS Grant Application

    We apply for your £7,500 Boiler Upgrade Scheme grant. This is deducted from your quote — you never pay the full amount.

  3. 03

    MCS-Certified Installation

    Our MCS-accredited engineers install the outdoor unit, connect it to your heating system, and commission it.

  4. 04

    Handover & Monitoring

    We walk you through the controls, set up remote monitoring, and register your MCS certificate.

What most customers ask first

The honest worries about heat pumps — 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

    Will a heat pump actually heat my house in January?

    How we handle it

    Yes — modern heat pumps are rated to deliver full design-day heat output at minus 7°C and continue running (with reduced output) at minus 15°C. The sizing calc bakes in your coldest reasonable day, not a mild average.

  • The worry

    How loud is the outdoor unit?

    How we handle it

    40–45 dB(A) at one metre — quieter than a household fridge. Permitted development rules cap it at 42 dB(A) at a neighbour's boundary, and we design to that figure then measure it on commissioning.

  • The worry

    Won't my electricity bill just go up?

    How we handle it

    It replaces your gas bill, not adds to it. On a heat-pump-optimised tariff (Octopus Cosy, OVO Heat Pump) the running cost is typically £100–£300 a year lower than equivalent gas — and the £7,500 BUS grant takes £7,500 off the install cost up-front.

  • The worry

    Will I need to rip out all my radiators?

    How we handle it

    Usually no, sometimes a handful. Rooms that were always slightly cool on gas often need a bigger radiator to keep up — typically one to three in a 3-bed. Our room-by-room calc tells us exactly which ones before we quote.

Grants and funding

Funding you may be eligible for.

Eligibility changes often. Our surveyor checks every active scheme for your home as part of the free survey, and handles the paperwork end-to-end if you qualify.

  • Boiler Upgrade Scheme (BUS) — £7,500 off every eligible air source heat pump install

  • ECO4 — stacks with BUS for benefits-receiving households, often covering the rest of the cost

  • 0% VAT on all heat pump installations through to March 2027

Common questions

Heat pumps — answered honestly.

Are heat pumps warm enough for UK winters?

Yes. Modern air source heat pumps work efficiently down to -20°C. They are widely used in Scandinavia where winters are far colder than the UK.

Do I need to replace my radiators?

Not always. Heat pumps run at lower temperatures than boilers, so some radiators may need upsizing. We assess this during your survey and include any changes in your quote.

How noisy is a heat pump?

Modern heat pumps operate at around 40-45 decibels — quieter than a fridge. They are designed to meet strict noise regulations.

What is the Boiler Upgrade Scheme?

The BUS provides £7,500 towards replacing a fossil fuel heating system with a heat pump. OMEGA handles the application and deducts the grant from your quote.

Will a heat pump increase my electricity bill?

Your electricity bill will increase slightly, but your gas or oil bill drops to zero. Overall, most homeowners see a net saving, especially with good insulation.
