Before you book: heat loss surveys in Machynlleth
In Machynlleth, 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.
Design outdoor temperatures for Machynlleth and the wider Powys come from local cold-weather data, not a national average. The survey in Machynlleth 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.
- Landlords comparing properties before deciding where to switch first
- Homes with an existing heat pump that seems undersized or expensive to run
- Anyone getting a heat pump quote, as the first step
What's included
- Room-by-room heat loss calculation using the MCS method
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
- Written results in your quote, or a stand-alone report if you order one
For Machynlleth homes with extensions or loft conversions, each part of the house is assessed on its own construction.
Grants and rules for heat pumps in Wales
Homes in Machynlleth can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Heat loss surveys in Machynlleth: questions
Do I need new radiators for a heat pump in Machynlleth?
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 Machynlleth home gives a room-by-room list.
How long does installation take in Machynlleth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Machynlleth home states the expected time.
What size heat pump does a Machynlleth 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 Machynlleth 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.
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.
