Before you book: heat loss surveys in Carnforth
Most homes can run on a heat pump if the system is designed properly, and Carnforth is no different. The key is matching the heat pump and radiators to the home's heat loss.
Houses in Carnforth built in different eras can need very different heat pump sizes, which is why each is calculated room by room. The survey in Carnforth 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.
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
What's included
- Recommended heat pump size and design flow temperature
- Hot water cylinder sizing for your household
- Written results in your quote, or a stand-alone report if you order one
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
Homeowners in Carnforth thinking about insulation work can use the survey to see how it would change their heat pump size.
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 Carnforth 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.

Heat loss surveys in Carnforth: questions
Where would the outdoor unit go on a Carnforth 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 Carnforth home.
Can you service a heat pump in Carnforth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Carnforth, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Carnforth 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 Carnforth home.
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.
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.
