Air conditioning for extensions and kitchen-diners in Penarth

For a kitchen-diner in Penarth, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year.

An extension in Penarth with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. We cover Penarth as part of South Glamorgan, roughly 3 miles from Cardiff. Homes in CF64 are all within our coverage.

Prices in Penarth

Air conditioning for extensions and kitchen-diners in Penarth typically comes in at £1,345–£4,095 per space including VAT, based on South and Mid Wales rates. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. Typical Large single work (one 5–7 kW unit for a large glazed space) lands around £1,895–£2,595 in this area.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.

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

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. On a survey in Penarth the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.

FAQ

Common questions in Penarth

How soon can you survey in Penarth?

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

Do you cover all of Penarth?

Yes, including CF64. We also cover nearby Dinas Powys and Cardiff.

How long does the installation take in Penarth?

Usually 1–2 days. We confirm the timing, and any days with no cooling or heating, in your written quote.

Who carries out the work in Penarth?

F-gas certified engineers working for Aircon Installers. Your contract is with S&K Property Investments and Improvement Ltd, which trades as Aircon Installers, and your quote names who will do the work and the F-gas company certificate that covers it.

Will the outdoor unit need planning permission in Penarth?

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.

Should I wait until the extension is finished?

It is better to plan it during the build so pipework is hidden, but it can be fitted afterwards.
