Before you book: heat loss surveys in Carlisle
Every property in Carlisle 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 Carlisle built in different eras can need very different heat pump sizes, which is why each is calculated room by room. A surveyor visits your Carlisle home to measure each room, window and wall before any heat pump is sized.
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
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Radiator schedule with any upgrades needed for each room
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
Design outdoor temperatures for Carlisle and the wider Cumbria 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 Carlisle 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 surveys in Carlisle: questions
How long does a heat pump survey take in Carlisle?
A home survey in Carlisle 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 long does installation take in Carlisle?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Carlisle home states the expected time.
Where would the outdoor unit go on a Carlisle 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 Carlisle home.
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.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
