What to know about heat loss surveys in Stowmarket
A heat pump suits most Stowmarket homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Homeowners in Stowmarket thinking about insulation work can use the survey to see how it would change their heat pump size. Design outdoor temperatures for Stowmarket and the wider Suffolk come from local cold-weather data, not a national average.
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
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Anyone getting a heat pump quote, as the first step
What's included
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
- Written results in your quote, or a stand-alone report if you order one
The survey in Stowmarket 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
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 Stowmarket quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
What to budget for heat loss surveys in Stowmarket
Guide prices for Stowmarket and the rest of Suffolk are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| 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.
Designing for Stowmarket's winters
Stowmarket has about 7 hours 42 minutes of daylight at midwinter and 16 hours 46 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.

Heat loss surveys in Stowmarket: questions
Where would the outdoor unit go on a Stowmarket house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Stowmarket home.
How soon can you survey a home in Stowmarket?
Survey dates depend on how busy installers are in Suffolk. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Ipswich as well as Stowmarket?
Yes. We arrange surveys and installation in Ipswich, which is about 11 miles south-east of Stowmarket, and across Suffolk.
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.
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.
