What to know about heat loss surveys in Corby
Homes around Corby range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Design outdoor temperatures for Corby and the wider Northamptonshire come from local cold-weather data, not a national average. Homeowners in Corby thinking about insulation work can use the survey to see how it would change their heat pump size.
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.
- Anyone getting a heat pump quote, as the first step
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
What's included
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
- Recommended heat pump size and design flow temperature
The survey in Corby includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
Grants and rules for heat pumps in England
Homes in Corby can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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 costs around Corby
The ranges below are typical installed prices for homes in Northamptonshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Corby can need quite different radiators and pipework.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Winter daylight and heating in Corby
Corby has about 7 hours 39 minutes of daylight at midwinter and 16 hours 50 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

- 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 Corby: questions
Do I need new radiators for a heat pump in Corby?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Corby home gives a room-by-room list.
How soon can you survey a home in Corby?
Survey dates depend on how busy installers are in Northamptonshire. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Corby that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Corby, whoever fitted them. Tell us the make and model when you book.
Will the survey check noise from the outdoor unit?
Yes. The surveyor identifies possible positions for the outdoor unit and carries out the MCS noise assessment, which estimates the sound level at the nearest neighbouring window from the unit's sound power level, distance and any barriers. In England, meeting the MCS planning standards is one of the conditions for permitted development. Wales, Scotland and Northern Ireland have their own rules, which we check.
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.
