Heat Pumps Specialists

A warm house all winter, without the bad-install horror story.

MCS Certified Manufacturer-Approved BUS Grant Registered
  • Wrongly sized.
  • Soaring electricity bills.
  • An installer who stops returning calls.

The difference is decided before anyone orders the kit.

The heat pump you never think about and the one that eats electricity are the same technology. What separates them is what gets measured in your house, room by room, before a single part is chosen.

Guess the size, and you find out in January, by which time the kit is already on the wall.

Approved installer for Vaillant Grant Kronotherm

Worried You'll End Up Cold, Overpaying, and Unable to Get Anyone Back?

"My first quote, from an independent installer, quoted 12K plus grant!! So almost 20K all in."
"Every installer gave me a different opinion, and I couldn't tell who was just trying to make a big sale."

Spend £8,000–£15,000 on a heat pump that's wrongly sized or badly installed, and you're left cold, overpaying on electricity, and unable to get the installer back, feeling like the one who was taken advantage of, despite being careful.

This isn't a knowledge gap. It's how the market works right now, and it's exactly what a measured survey exists to prevent.

How We Take the Guesswork Out

Here Is Exactly What a Correctly Specified, Properly Installed Heat Pump Looks Like.

  • Full heat loss calculation completed before your quote is written: we measure your property room by room using BS EN 12831 methodology. The system is sized from evidence, not estimation. And you see the calculation.
  • A named, accredited engineer on your job: not a faceless rotating crew. It's Jamie or Louie every time, and you'll know exactly who is coming, and can check their credentials, before they set foot in your home.
  • Every quote itemised line by line: heat pump unit, radiator upgrades if needed, hot water cylinder, controls, commissioning, and grant paperwork. No hidden costs emerge after you've committed.
  • Commissioning completed and signed off in writing: your system is tested at operating temperature before we leave. You receive a written commissioning report, not a verbal confirmation.
  • Aftercare with a named contact and a 24-hour response commitment: if something is wrong after installation, you call one person. Not a call centre. Not a generic inbox.
  • Grant paperwork handled in full: we submit the Boiler Upgrade Scheme application on your behalf. The £7,500 is deducted from your invoice. You never handle the grant process.

Every installation is managed by Jamie, Heat Geek verified, manufacturer-approved, with 9 years in heat pump installation.

Nick WigstonVerified Google review

Air Source Heat Pump · 12kW Vaillant aroTHERM

"After the process went through the Heat Geek platform, a 12kW Vaillant aroTHERM was designed to meet the strict efficiency standards, so it runs as cheaply as possible. The family have said the house has never been warmer, at times it feels like we have underfloor heating. Jamie gave me total confidence in his ability, specifically his deep knowledge of system design under the Heat Geek methodology."

Air Source Heat Pump · Full System Installation

"Not sure if you will find anyone more enthusiastic about heat pumps. Although not everything went perfectly (when does it), Jamie and his team ensured that everything was amended. Even though he lives about 15 miles away, he popped round twice on the Saturday to make sure everything was running properly."

Heat Pumps & Underfloor Heating · New Build

"Jamie installed the heat pumps on my two new-build bungalows, the underfloor heating, the bathrooms and kitchens. His level of detail is second to none and so is his work. I couldn't recommend Jamie highly enough, he truly cares about what he does and is your go-to man."

What We Do

What We Install, What It Covers, and What Happens at Each Stage.

Air Source Heat Pump Installation

A complete heat pump installation sized to your specific property using a full heat loss calculation, the unit, the controls, and all associated pipework. Radiator upgrades and a hot water cylinder are included where the survey shows they're needed.

Radiator Upgrades & System Optimisation

If your existing radiators are undersized for heat pump flow temperatures, we replace or supplement them as part of the installation package, priced transparently in your quote before any commitment.

Boiler Upgrade Scheme Grant Applications

We handle the full BUS grant application process on your behalf. The £7,500 grant is deducted directly from your invoice, you do not pay it upfront and claim it back. The paperwork is ours, not yours.

Post-Installation Commissioning & Aftercare

Common Questions

Questions We Get Asked Every Week

We answer the questions other installers avoid. Because if you're asking them, they matter, and every answer here is a mechanism you can verify, not a reassurance.

Get My Free Cost Estimate Or book a call about a heat loss survey, we confirm the fee for your property first.
Every installation begins with a full heat loss calculation completed room by room, using BS EN 12831 methodology, the British Standard for heating load assessment. You receive the calculation document before we write your quote. The unit is specified from measured data, not an estimate. If the calculation shows a larger unit is needed, that is in your quote, not discovered after installation.
The difference is almost always in what is included. Our quotes itemise every component: the heat pump unit, any radiator upgrades, the hot water cylinder, pipework, controls, commissioning, and grant paperwork. A quote that is £3,000 lower may exclude the cylinder, radiator upgrades, or the commissioning stage, work that is still required and will be invoiced separately. We provide a full scope of work in writing before you commit. Ask any installer to itemise their quote to the same level and compare like for like.
The heat loss survey is the honest answer to this question. It tells us exactly what your existing radiators can deliver at heat pump flow temperatures and whether any need replacing. If upgrades are needed, they appear in your quote before you commit, not as a surprise invoice halfway through the job. We will not recommend a heat pump for your property if the survey shows it is not the right solution.
Your quote shows the pre-grant price and the post-grant price separately, in writing. The grant is deducted directly from your invoice, you do not pay it upfront and claim it back. If you want to compare, ask for the pre-grant figure from any installer you approach and benchmark that number. The Boiler Upgrade Scheme payment goes directly to us from Ofgem, the process is auditable and the figures are independently verifiable.
The critical figure is the Coefficient of Performance (COP), for every 1 unit of electricity a heat pump uses, it produces 3–4 units of heat. A gas boiler produces less than 1 unit of heat per unit of gas. At current UK energy prices, a correctly sized and commissioned heat pump running on a heat pump-specific tariff (such as Octopus Cosy or similar) typically costs less to run than a gas boiler for the same property. We provide real running-cost data from comparable UK installations during your survey, not theoretical marketing figures.

No Pressure. No Deposit.

No Deposit Until You've Seen the Full Survey Results in Writing.

The cost estimate is free and instant. If you go further, the heat loss survey gives you the calculation, the itemised quote, and the grant figures, all in writing, before any payment toward an installation is requested. Decide not to proceed, and there's no obligation. The first financial commitment you make is to a fully documented, fully costed installation, not a guess. The survey itself is a paid visit; we confirm the fee for your property on a quick call before you book.
