HOW IT WORKS

From your first call to a warm home: four simple steps

We handle everything: survey, system design, grant application, installation, and aftercare. Here's what to expect.

01

Free home assessment
We visit your property, carry out a full room-by-room heat loss survey, and confirm whether a heat pump is right for your home. No obligation, no pressure.

02

Written quotation
You receive a fully itemised written quote. We calculate your grant eligibility and apply for BUS voucher directly (£7500 - £9,000), no paperwork for you.

03

Installation day
Most installations take 2–3 days. Our engineers are tidy, MCS-certified, and will walk you through the new system before they leave.

04

Aftercare & guarantee
Your product guarantee is registered. Our HeatCare Renewable service plan keeps the system performing for years to come.

We have just had our bathroom renovated by South West Plumbing. Nathan, the fitter, was absolutely superb. His attention to detail was faultless. Nothing was too much trouble and the end result was fantastic. It made our shabby old bathroom, look brand new. We could honestly not have had a nicer fitter in Nathan and quality products from South West Plumbing. Thank you to all at South West Plumbing.

South West Plumbing are a very reliable and well organised business. We have used them on several occasions and recently had some work done by them. We were kept updated. Their plumber was polite tidy and very helpful. The work was done quickly and to a high standard. The price was reasonable.

South West Plumbing kept our old boiler running for ages. When the time came for a replacement the engineer Jack did a really good job swapping out our old one for a new one, cleaning the system and set us up hopefully for another decade and a half.
