Before you book: heat loss surveys in Colchester
In Colchester, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
For Colchester homes with extensions or loft conversions, each part of the house is assessed on its own construction. The survey in Colchester 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.
- Homes with an existing heat pump that seems undersized or expensive to run
- Anyone getting a heat pump quote, as the first step
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Radiator schedule with any upgrades needed for each room
- Recommended heat pump size and design flow temperature
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
Design outdoor temperatures for Colchester and the wider Essex come from local cold-weather data, not a national average.
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 Colchester 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.

Short winter days in Colchester and what they mean
On the shortest day Colchester gets about 7 hours 46 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Heat loss surveys in Colchester: questions
Where would the outdoor unit go on a Colchester 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 Colchester home.
How long does a heat pump survey take in Colchester?
A home survey in Colchester 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.
How soon can you survey a home in Colchester?
Survey dates depend on how busy installers are in Essex. We offer the next available dates when you enquire and confirm them in writing.
Is the heat loss survey free?
Yes, for installation enquiries the home survey and heat loss calculation are free, and the results form the basis of your written quote. If you only want the calculation and report, for example for building plans or comparing quotes, a stand-alone heat loss survey has a guide price of £150–£400, including VAT. We confirm which applies when you book.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
