What to know about heat loss surveys in Salisbury
Every property in Salisbury 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.
For Salisbury homes with extensions or loft conversions, each part of the house is assessed on its own construction. A surveyor visits your Salisbury 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
- Anyone getting a heat pump quote, as the first step
- Landlords comparing properties before deciding where to switch first
What's included
- Outdoor unit siting options and noise check
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
Design outdoor temperatures for Salisbury and the wider Wiltshire come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
Homes in Salisbury 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.
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.

Designing for Salisbury's winters
On the shortest day Salisbury gets about 7 hours 54 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.
How installation works in Salisbury
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Salisbury home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat loss surveys in Salisbury: questions
Do you cover Amesbury as well as Salisbury?
Yes. We arrange surveys and installation in Amesbury, which is about 7 miles north of Salisbury, and across Wiltshire.
Where would the outdoor unit go on a Salisbury 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 Salisbury home.
How soon can you survey a home in Salisbury?
Survey dates depend on how busy installers are in Wiltshire. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
