Heat load surveys and system design in Ystradgynlais

Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer. Every Ystradgynlais quote starts with a room-by-room survey rather than a guess from floor area.

No two rooms in Ystradgynlais gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our Powys coverage takes in Ystradgynlais, about 55 miles from Newtown. That includes the SA9 postcode district.

Planning and permissions

In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.

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.

Every job in Ystradgynlais includes:

FAQ

Common questions in Ystradgynlais

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

Our guide range in South and Mid Wales is £365–£1,145 for a standalone design pack, including VAT. The exact price depends on the rooms, the pipe route and access, and we confirm it in writing after a free survey.

How soon can you survey in Ystradgynlais?

We offer survey dates when you enquire. Early summer is the busiest time, so spring and autumn are the easiest times to book.

Will the outdoor unit need planning permission in Ystradgynlais?

Since 1 June 2026, most houses in Wales can have an outdoor unit under permitted development if it meets the size, number and MCS 020a noise conditions. Flats, listed buildings and conservation areas need more care. We check on survey.

Is the survey in Ystradgynlais really free?

Yes, for new installations. The survey and written quote are free and there is no obligation to go ahead.

Can I get a price for Ystradgynlais without a visit?

Yes, our online guide price tool gives a range in about a minute. A fixed price needs a survey, which is free for new installations.

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.
