Guides

Straight answers about air conditioning.

What it costs, what it costs to run, whether you need permission and whether it heats. Written from the survey and installation side of the job, which is why they name the limitations as well as the benefits.

Air conditioning installation across London. Based in Harrow and Stanmore.

Most air conditioning advice online is written to sell rather than to answer. These are written the other way round. Every price comes from our own published price list, every efficiency figure from the manufacturer’s own published data, and every planning rule from the legislation or the Planning Portal. Where something could not be verified, it is not here.

Answers first

Each guide opens with the answer in one paragraph. Read that and stop, if that is all you needed.

The limits named

Every range and every system has something it does badly. A page that does not say so is a brochure.

Figures you can check

Running costs show the arithmetic and the rate they use, so you can test them against any quote.

How much does air conditioning cost in London?

The starting figure is the easy part. This is what London itself does to it, and what the second room costs once you have had the first.

What does air conditioning cost to run?

Real figures from published efficiency data and the current price cap, with the arithmetic shown so you can check it against any unit you are quoted.

Do I need planning permission for air conditioning?

The permitted development rules, what they actually say, and the one clause that decides whether your install needs an application.

Can I install air conditioning myself?

A straight answer to the question, with the two laws that decide it and what you can legally do without either.

Can air conditioning heat my home in winter?

It heats, it works in a cold snap, and it is several times cheaper to run than an electric heater. Here is what the manufacturers publish, and where the honest limits are.

Daikin vs Mitsubishi Heavy Industries

Two of the most asked about names in the trade, one of which is really two companies. What the published figures actually say.

Daikin vs Samsung

Two brands we fit side by side, and a comparison where the cheaper one wins more often than people expect.

Daikin Comfora vs Daikin Stylish

Two Daikin wall units, sold side by side, with a real price gap between them. What you actually get for it.

Still got a question

Ask us the one the guides do not answer.

A road name and a rough room size is enough for a starting price on the phone. No obligation, and no visit needed to have that conversation.
