Why Homeowners Look for Octopus Energy Alternatives
Octopus Energy has become one of the biggest names in the UK heat pump market, and for good reason — they manufacture their own units, offer competitive pricing, and have made the process of switching from a gas boiler far more accessible than it was even two years ago. But as thousands of homeowners across London and Surrey have discovered, the national-scale model comes with trade-offs that matter when it is your home on the line.
The most common frustration we hear is lead times. Octopus typically quotes 4 to 8 weeks from survey to installation, and during peak demand periods that window can stretch further. For homeowners whose boiler has already failed or who need work coordinated with a wider renovation, waiting two months is not always practical. There is also the fact that Octopus does not offer solar panel installation — if you want to pair your heat pump with a PV array to offset running costs, you will need to manage a second contractor, a second scaffold, and a second schedule.
Finally, many homeowners simply prefer dealing with a local, named installer rather than a national call centre. Octopus relies on a mix of in-house teams and regional subcontractors, and the quality of communication can vary. When something goes wrong — a pipe route that needs rethinking, a radiator that needs upsizing — being able to pick up the phone and speak directly to the engineer who surveyed your property makes a real difference. That is the gap a specialist local firm like Electromatic M&E is built to fill.
Octopus Energy Heat Pumps at a Glance
To be fair, Octopus Energy deserves credit for driving down the cost of heat pump installation in the UK. Here is what they bring to the table — and where the gaps are.
Strengths:
- Lowest headline price — typical cost after the £7,500 BUS grant (subject to eligibility) is £2,500 to £5,000, with an average around £3,818. In-house manufacturing and volume purchasing keep costs well below most competitors.
- Free EPC check and asbestos test included in the survey process.
- Cosy Octopus tariff — a time-of-use electricity tariff with cheap off-peak rates, designed specifically for heat pump households.
- 7-year warranty on the heat pump unit.
- 4.8/5 on Trustpilot across 775,000+ reviews (note: this rating covers all Octopus Energy services, not heat pumps alone).
- MCS certified under their own accreditation.
- BUS grant (subject to eligibility) handled and deducted automatically.
Weaknesses:
- No solar panel offering — you cannot bundle ASHP and PV through Octopus, meaning a second contractor and potentially higher total project cost.
- National service model — your surveyor, installer, and aftercare contact may all be different people in different locations.
- 4-8 week typical lead time, sometimes longer during busy periods.
- Subcontractor variability — while Octopus has strong internal quality standards, some installations are carried out by third-party teams whose communication and workmanship can vary.
- Limited scope — Octopus installs the heat pump, but does not typically handle wider electrical upgrades, plumbing modifications, or boiler removal as part of a single coordinated project.

What Makes Electromatic Different
Combined M&E — One Contractor, One Project
Most heat pump installers are exactly that — heat pump installers. If you need your consumer unit upgraded, your radiators swapped, your old boiler decommissioned, or a solar array wired in, you are looking at two, three, or even four separate trades.
Electromatic M&E is a full mechanical and electrical contractor. We handle heat pumps, solar PV, electrical work, and plumbing under a single contract. That means one survey, one project timeline, one point of accountability, and no finger-pointing between trades if something needs adjusting. For homeowners doing a whole-house energy upgrade, this saves weeks of coordination and often reduces the total cost compared to managing multiple contractors.
Local Presence — Hampton, Richmond, Kingston, Twickenham
We are based in the TW postcode area and work across London and Surrey. That is not a line on a website — it means your surveyor lives locally, your installer knows the housing stock (Victorian terraces, 1930s semis, post-war estates), and if there is a snag on site, the person who can fix it is 20 minutes away, not 200 miles.
Our typical turnaround from survey to installation is 2 to 4 weeks — roughly half the Octopus average. For urgent cases, we can often move faster.
Gas Safe Registered + Heat Pump Installer
Electromatic engineers hold Gas Safe certification alongside heat pump qualifications. This matters because most heat pump installations involve removing an existing gas boiler — a task that legally requires a Gas Safe registered engineer.
With Octopus or other heat-pump-only installers, you may need to arrange a separate Gas Safe engineer to decommission the old system before the heat pump team arrives. With Electromatic, your old boiler comes out and your new heat pump goes in during the same visit, by the same team.
No Sales Pressure
We do not employ sales representatives. There is no high-pressure home visit, no “sign today for a discount,” no manufactured urgency. You get a technical survey, a clear written quote with itemised costs, and as much time as you need to make a decision.
Our quotes include the full £7,500 BUS grant (subject to eligibility) deduction, 0% VAT, and a breakdown of every component so you know exactly what you are paying for.
£7,500 BUS Grant (subject to eligibility) — Handled End-to-End
The Boiler Upgrade Scheme grant is worth £7,500 towards the cost of an air source heat pump. Electromatic handles the entire application process on your behalf — from the initial EPC check through to Ofgem registration and grant redemption. You never need to fill in a government form or chase a reference number. The grant is deducted from your invoice before you pay.
Who Should Choose Octopus Energy
We believe in being honest. Octopus Energy is a strong choice if:
- You want the absolute lowest upfront cost for a heat pump installation and do not need solar panels.
- You are located outside London and Surrey and need a national installer.
- You value the Cosy Octopus tariff for ongoing electricity savings and want everything with one energy supplier.
- Your property is relatively straightforward — a modern detached or semi-detached home with adequate space, no complex pipework, and no need for wider electrical or plumbing work.
If price is the single deciding factor and you only need a heat pump, Octopus is hard to beat on headline cost.
Who Should Choose Electromatic
Electromatic is the better fit if:
- You want heat pump and solar panels installed together as a single, coordinated project — reducing total cost, disruption, and the number of contractors on site.
- You are in London, Surrey, Richmond, Kingston, Twickenham, or the wider TW postcode area and want a genuinely local installer who knows the housing stock.
- You want one contractor to handle electrical upgrades, plumbing, boiler removal, heat pump installation, and solar — with a single point of contact throughout.
- Your property is a complex retrofit — older construction, limited space, non-standard pipework, or a consumer unit that needs upgrading before a heat pump can be connected.
- You want a faster turnaround — our 2-to-4-week timeline suits homeowners who cannot afford to wait two months.
- You prefer direct, personal service over a call-centre experience, with no sales pressure and a named engineer you can reach by phone.

FAQ
Is Electromatic cheaper than Octopus Energy for a heat pump?
No — Octopus Energy typically offers a lower price for a standalone heat pump installation, thanks to their in-house manufacturing and volume scale. However, if you are planning to add solar panels as well, Electromatic’s combined ASHP + Solar package (from £8,000 after grant) can work out more cost-effective than hiring Octopus for the heat pump and a separate solar installer for the panels. You also save on the overhead of managing two projects.
Does Electromatic handle the BUS grant (subject to eligibility)?
Yes. We manage the entire Boiler Upgrade Scheme application from start to finish. The £7,500 grant is deducted from your invoice before payment, and you do not need to deal with Ofgem or any government paperwork. The process is identical to what Octopus offers — the grant is the same regardless of which MCS-certified installer you choose.
Can Electromatic remove my old gas boiler?
Yes. Our engineers are Gas Safe registered, which means we can legally decommission and remove your existing gas boiler as part of the heat pump installation. This is a genuine advantage over heat-pump-only installers, where you may need to arrange a separate Gas Safe engineer to remove the old system before the new one can go in.
What areas does Electromatic cover?
We are based in the TW postcode area and cover Hampton, Richmond, Kingston, Twickenham, and the wider London and Surrey region. If you are unsure whether your property falls within our service area, get in touch and we will let you know straight away.
Is Electromatic MCS certified?
Yes. Electromatic holds MCS certification through an umbrella partnership, which is a recognised and fully compliant route to MCS accreditation. This means our installations qualify for the £7,500 BUS grant (subject to eligibility) and meet the same technical standards as any directly MCS-certified installer, including Octopus Energy.
Why would I pay more for Electromatic instead of going with Octopus?
The price difference reflects what you get: a local, multi-trade contractor who can handle your entire energy upgrade — not just the heat pump. If your project involves solar panels, electrical work, boiler removal, or any complexity beyond a straightforward heat pump swap, Electromatic delivers the whole job under one roof. You also get faster lead times, direct access to your installer, and the peace of mind that comes from working with a named local business rather than a national operation.
