From survey to lifetime service.

More than a heat pump. A futureproofed home.

We design, install and look after intelligent renewable systems. From heat pumps, solar PV and battery, to smart-tarrif integration. Engineered to keep a home warm, low-carbon and low-cost for the next thirty years. Not a like-for-like boiler swap; a home designed around the way you’ll live.

Why we exist

Whole System Design for Your Home

Air source heat pumps are becoming the standard way to heat a home. They are quick to fit, widely available, and for a straightforward swap that’s no bad thing. But we stopped competing on the straightforward, oil, gas, LPG swap years ago. Our fifteen years experience, means we prefer to focus on the whole-house design and a system built to be efficient and futureproof.

Trust Pilot rating

"South West Heat Pumps considered cooling from the outset helping me to choose the right brand of heat pump and emitters tailored for each room. Short version, cooling was considered at the start of the design not as an afterthought."

Design & Installation

The considered, design-led team.

Heat-loss design, ground & Air source, solar, battery and hybridisation. All specified around your home, not a price list. This is what we excel at.

Service Division

Any heat pump, any brand, across the South West.

The projects we design for.

Every project is a whole, intelligent system. We design systems with heating, cooling solar and storage working together, not just a replacement heat source.

01

Retrofit & futureproof

Transform an existing home into an intelligent, low-carbon system: heat pump, cooling, solar PV, battery and smart-tarrif integration working together. Designed to cut bills and carbon, not just swap the boiler. 

02

New build

Designed in from a blank page. The lowest-carbon, lowest-running-cost home from day one – ground or air source, underfloor heating, MVHR and PV hybridisation integrated into the architecture.

03

Retro modernisation

Bringing a substantial or period property up to modern performance. Design-led upgrades, correctly sized low-temperature emitters and an intelligent system that suits how the home is really used.

04

Light commercial

Offices, workshops, hospitality and small commercial buildings — the same design-led, futureproofed approach, scaled up and designed around how the building is really used.

The Proof

Our Projects, in depth.

Every install is different. Here’s what “design-led” actually looks like on the ground.

A 1930s home with solid walls and no obvious route to a heat pump. Full fabric-first survey, low-temperature emitters throughout, and a ground array sized around the garden rather than the budget.

SWHP performance

“From the start 5 years ago when the ground source system was installed and since then with the annual service visits, SWHP have been helpful, reliable, efficient and engaging. The SWHP folk mirror the service that the company provides.
Thank you”

I was so impressed with the service

“I was so impressed with the service. It was easy to arrange an appointment, the service was prompt, friendly and efficient – followed up by emails. The engineers clearly knew their job and were so lovely and friendly. I unreservedly recommend South West Heat Pumps.”

Mitsubishi heat pump system

“We had SWHP install our system 5 years ago and they were really helpful and on it! It works like a dream. Sue takes care of the admin and always super helpful. Our yearly service just done by Martin recently who was a great guy and very knowledgeable … went the extra mile!”

The Thinking

A heating system considers four elements.

Renewable heating decisions made today shape bills, comfort and compliance for the next thirty years. We design every element to work as
one.

01

The renewable source

Ground, air or water, all are  sized from a proper heat-loss calculation, not a rule of thumb. Where geology allows, ground source for the highest efficiency and lowest running cost.

02

What the system delivers

Heating, hot water and cooling. Include solar PV and battery so the home generates and stores its own energy, and is ready for time-of-use smart tariffs.

03

How energy meets the room

Underfloor heating, correctly sized radiators or fan coils – or a considered mix – 
all designed for efficient low-temperature flow.

04

The intelligence that ties it together

Controls, monitoring and smart-tariff integration that run the whole system
intelligently. Hybridised, optimised and futureproof.

The Equipment

Two manufacturers, chosen on merit.

We specify Ecoforest and Maxa only. Chosen for their advanced specification: smart-tariff ready, hybridisation capable and built to integrate with solar and battery. We lead with ground
source: our signature expertise.
