Before you book: heat loss surveys in Lydney
The question for a Lydney home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Homeowners in Lydney thinking about insulation work can use the survey to see how it would change their heat pump size. A surveyor visits your Lydney 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.
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
What's included
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- Recommended heat pump size and design flow temperature
- Room-by-room heat loss calculation using the MCS method
- Electrical supply and network operator notes
For Lydney homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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 Lydney 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.
What to budget for heat loss surveys in Lydney
The ranges below are typical installed prices for homes in Gloucestershire, including VAT. A survey sets the exact figure, because two similar-looking houses in Lydney can need quite different radiators and pipework.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Lydney's winters
Lydney has about 7 hours 47 minutes of daylight at midwinter and 16 hours 41 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Heat loss surveys in Lydney: questions
Do you cover Dursley as well as Lydney?
Yes. We arrange surveys and installation in Dursley, which is about 8 miles south-east of Lydney, and across Gloucestershire.
How soon can you survey a home in Lydney?
Survey dates depend on how busy installers are in Gloucestershire. We offer the next available dates when you enquire and confirm them in writing.
Do I need new radiators for a heat pump in Lydney?
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 Lydney home gives a room-by-room list.
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.
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.
