Compare quotes for heat pump system design and sizing in Giffnock
An oversized heat pump cycles on and off and wastes money, while an undersized one leaves rooms cold in a freeze. Note any extensions or insulation planned.
Send one enquiry for Giffnock, and up to four independent heat pump businesses may respond, depending on the work involved and who has capacity. Matching costs nothing, and every quote can be declined.
Work to include in your enquiry
Design starts with a room-by-room heat loss calculation: walls, windows, floors, roof and ventilation for each room in the home. The result decides the heat pump size, the radiators or underfloor circuits, the pipe sizes, the cylinder and the controls. A written design pack should record all of this so installers can price from it.
Things to mention when you enquire
- A heat pump quote with no heat loss calculation
- One installer saying 8kW and another 14kW
- A planned extension or insulation upgrade
- An older property where heat loss is hard to judge
- A grant application that needs documents
How the design is produced
The designer needs measurements for every room. A typical job includes:
- Recording each room, the walls, windows, floors, roof and any extensions.
- Calculating the heat loss per room and for the whole house at the design outdoor temperature.
- Specifying the heat pump size, cylinder, emitters, pipework and controls to match.
- Checking the existing radiators and pipes against the design flow temperature.
- Producing a design report you can pass to installers for like-for-like quotes.
Desktop design or full survey
A desktop design works from drawings and photographs you supply and costs less, but it can miss details such as cold floors or ventilation. A full survey includes a visit, measures the rooms and inspects the existing heating. Ask which one is quoted, and what it includes if the design is later changed.
Preparing for the visit
Have drawings, loft and wall details and any energy performance certificate to hand. Ask whether you will own the design, whether it can be given to any installer and whether it counts for grant paperwork.
What the written design should show
Have uncertain wall and floor constructions marked as assumptions. Request the design outdoor temperature, target room temperatures and flow temperature. An installer should review the report against the actual equipment before ordering.
Prices for heat pump system design and sizing in Giffnock
A sensible planning figure is £300–£1,200. A quote may fall below or above this range. A desktop heat loss calculation for a typical house sits at the lower end. A full survey and design pack for a medium home is in the middle. Large or complex properties, listed buildings, multiple heating zones and full commissioning documents take the price to the top of the range or beyond.
Ask for the survey, calculations and design report to be priced clearly, with VAT stated. Allow 1–5 days as a guide for the work itself; survey availability, missing measurements and revisions can add to it.
Information that speeds up a quote
Give the address, the approximate age and construction of the house, the floor area, the number of rooms and any extensions or insulation planned. Say whether you already have a heat pump quote that you would like checked.
Go through every quote item by item. Ask what the design pack includes: room-by-room heat loss, heat pump sizing, emitter checks, cylinder sizing, pipe sizes and an estimate of running costs. Check whether the design follows MCS requirements and whether it can be reused with any installer.
Regulations and approvals
A design report does not need planning permission or building regulations approval. For a grant under the Boiler Upgrade Scheme the installer must be MCS certified, and MCS standards set out how the heat loss calculation and design are carried out. Ask the designer which standards they follow.
If you are not sure whether the council needs to know, ask East Renfrewshire Council. If the job grows beyond what was quoted, confirm which approvals apply before the extra work starts.

Roughly how much is heat pump system design in Giffnock?
We use £300–£1,200 as a UK guide. Businesses in Giffnock price their own work, and the size of the house, whether a visit is needed and what the report covers affect the total. A written quote should list the survey, calculations, design documents, revisions and VAT.
What is a heat loss calculation?
It estimates how much heat each room loses on the coldest design day, based on its size, walls, windows, floors, roof and ventilation. It is the starting point for sizing a heat pump and radiators.
Can I use the design with any installer?
Usually, if the designer provides it as an independent report. If the design is part of an installer’s own quote, ask whether you can keep it and use it elsewhere.
Is a heat pump design free?
Some installers include a basic design in their quote. An independent design costs money, but it gives you a document to compare quotes against.
How long should I allow for heat pump system design?
Allow 1–5 days as a guide. Ask what the design pack contains and whether you keep it to use with any installer. Survey availability and revisions can add time. A design visit does not normally interrupt the heating.
