Just joined Octopus 28th February 2026. I phoned because I wanted a smart tariff "Snug" for my storage heaters. Spoke to "Will" and he was very helpful and new what I wanted. It was very smooth and informative. Got all info sent in emails minutes later, that told me all the advantages of joining Octopus. Apart from having the cheapest tariff rates, I had a referral code from a friend, so I get £50 credit. I informed my daughter of the great deal and she joined last night with my referral, another £50. So I get connected 4th March and already have £100 credit on my account. The app is brilliant, all the info you need. Get transfering over to Octopus.

Octopus Energy are by far the best supplier of energy that I've ever dealt with. As an ageing hippy I'm greatly appreciative of the way they sign their documents with 'love and power' although I frequently misquote this as 'peace and power'. I'd really like to tell you how useless lesser energy suppliers are in comparison but I fear Google may disallow my comments relating to the awful Spottish Sour (sic.... it rhymes with), my previous supplier, who caused me years of frustration and anger with the way they didn't care. There were teething problems with the transfer to Octopus 🐙 but they were quickly ironed out and solved by the excellent customer services team. Communication with Octopus works wonderfully both ways, them to me and vice-versa. Octopus also allow their customers the freedom to choose how much to pay each month to a large extent. I strongly recommend that if you're not with Octopus you should transfer to them as soon as is possible, you'll never regret the move.

Octopus have been great for me. Swapping to them was easy, moving house - no problem. My gas smart meter wasn't working properly, soon sorted. Customer service is excellent. I had a call re sorting my gas smart meter literally as my mum just passed away. The next day, a beautiful bouquet of flowers arrived. The reccomend a friend is great, my 2nd £50 is on it's way. Would definitely recommend.

Spent so long fighting British Gas on a monthly basis to get correct bills. I now have peace of mind since switching to Octopus. If I have an issue it is now resolved by someone who I can easily understand through a simple phone call. I now feel so satisfied with Octopus that I can recommend them to friends and we both get a £50 reward.

Octopus are a pleasure to work with. The app is easy and understandable. Any queries sent by email are responded to thoroughly, politely and promptly. Rates are competitive and lots of tarriffs to choose from. What are you waiting for? Octopus help customers by sending out electric blankets to those in need. Switching is a breeze & you & a friend can share £100 for doing so. Would never contemplate using a different energy supplier. Well Done & Thank you 🦑

Frequently asked questions

How do I know you’re properly qualified and certified to install heat pumps?

We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).

Can you tell me if a heat pump is actually suitable for my home?

We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.

What type and size of heat pump will you recommend for my property, and why?

We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.

What will the full installation cost be, and what’s included in your quote?

Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.

Can you help me access government grants like the Boiler Upgrade Scheme?

Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.

How much disruption should I expect during installation, and how long does it take?

A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.

Will I need to replace my radiators or upgrade anything else in my home?

After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.

How noisy is the outdoor unit and where will it be installed?

Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.

What warranties, servicing and aftercare do you provide?

You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.

What running costs and savings can I realistically expect compared to my current boiler?

We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
