Heat load surveys and system design across County Down

For self-builds and extensions in Bangor, a standalone design pack can go straight to your builder. No two rooms in Bangor gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. In Northern Ireland, cooling is mostly needed in conservatories and glazed rooms, while efficient heating benefits the whole home.

Prices in County Down

In Northern Ireland, our guide range for heat load surveys and system design is £365–£1,145 for a standalone design pack, including VAT. Labour rates in Northern Ireland keep this slightly under the national middle. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. On our Northern Ireland figures, the Design pack option (drawings and schedules for one home) is about £365–£745.

Planning and permissions

Northern Ireland has its own planning rules for outdoor units, and conservation areas and listed buildings need particular care. We confirm the position for your property before installation.

The survey

The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.

FAQ

Heat load surveys and system design in County Down

Will the outdoor unit need planning permission in County Down?

Northern Ireland has its own planning rules for outdoor units. We confirm the position for your home on survey, and with the council where needed.

All of County Down, including Bangor, County Down, Newtownards, Newry and Banbridge. Each town has its own page below with local details.

How much do heat load surveys and system design cost in County Down?

Our Northern Ireland guide range is £365–£1,145 for a standalone design pack, including VAT.

Is the survey free?

Yes, for new installations on the mainland. The survey and written quote are free and there is no obligation.

Do I get the calculations?

Your quote shows the capacity chosen for each room. Standalone design packs include the full calculations.

Why can't you just quote from floor area?

Two rooms the same size can need very different units because of glazing, orientation and use. Sizing from floor area alone is the main cause of systems that never feel right.
