What to know about heat loss surveys in Henley-on-Thames
Every property in Henley-on-Thames 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.
Design outdoor temperatures for Henley-on-Thames and the wider Oxfordshire come from local cold-weather data, not a national average. For Henley-on-Thames homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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
- Landlords comparing properties before deciding where to switch first
- Self-builders and architects who need emitter and system sizes early
What's included
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
The survey in Henley-on-Thames 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
Homes in Henley-on-Thames 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.
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.

How long is the heating season in Henley-on-Thames?
On the shortest day Henley-on-Thames gets about 7 hours 49 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.

Heat loss surveys in Henley-on-Thames: questions
Do you cover Marlow as well as Henley-on-Thames?
Yes. We arrange surveys and installation in Marlow, which is about 6 miles north-east of Henley-on-Thames, and across Oxfordshire.
Do I need new radiators for a heat pump in Henley-on-Thames?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Henley-on-Thames home gives a room-by-room list.
How soon can you survey a home in Henley-on-Thames?
Survey dates depend on how busy installers are in Oxfordshire. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
