Heat loss survey in Redruth: what to expect
Every property in Redruth is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Houses in Redruth built in different eras can need very different heat pump sizes, which is why each is calculated room by room. The survey in Redruth includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
Every heat pump we quote starts with a room-by-room heat loss survey, free with installation enquiries and also available as a stand-alone report.
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Recommended heat pump size and design flow temperature
- Written results in your quote, or a stand-alone report if you order one
- Room-by-room heat loss calculation using the MCS method
A surveyor visits your Redruth home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Redruth quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Heat loss survey prices in Redruth
Here are typical prices for heat loss surveys in Cornwall, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.

Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Redruth's winters
On the shortest day Redruth gets about 8 hours 02 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.
The steps for heat loss surveys in Redruth
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Redruth; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat loss surveys in Redruth: questions
What size heat pump does a Redruth home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Redruth home.
How long does a heat pump survey take in Redruth?
A home survey in Redruth usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do you cover Camborne as well as Redruth?
Yes. We arrange surveys and installation in Camborne, which is about 4 miles south-west of Redruth, and across Cornwall.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
