Air conditioning installation in Hook, Greater London
Air conditioning in Hook from an F-Gas certified company, with the manufacturer’s warranty terms explained on your quote. Enquiries answered the same working day.
- A room that’s unbearable on warm days
- Fans and portables that don’t keep up
- Not knowing which system, size or brand to choose
How the visit works
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, which takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. A few pictures of the room, the outside wall and the fuse board help us plan a job in Hook.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Tell us about any building rules, permits or sign-in
- Move furniture away from the wall where we will be working
- Make sure we can reach the outdoor unit, or where it will go

Air conditioning in Hook
Any installation we do in Hook follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. When someone in Hook asks us for air con, the first questions are normally price and who will fit it. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
A typical install in Hook is an indoor unit high on an outside wall, a neat pipe run and an outdoor unit on a bracket or ground pad, with the drain run planned so it never drips where it shouldn’t.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Your questions about air conditioning in Hook
Can I fit air conditioning in Hook without planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Hook holds about 3 listed buildings and structures. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with Kingston-Upon-Thames council, which is normally the planning authority for Hook.
Can you fit air conditioning in a London flat in Hook?
Usually, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can air conditioning heat my home as well?
In most cases, yes: modern splits are normally heat pumps, so they heat as well as cool. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.
Do you offer emergency call-outs?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Should I choose wall-mounted, ducted or cassette?
There’s no single best type. Wall-mounted splits suit single rooms, multi-splits run several rooms from one outdoor unit, ducted systems hide the unit in the ceiling, and cassettes suit offices and larger rooms. We recommend one on the survey and explain why.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
When to call us in Hook
Loft rooms and top floors tend to suffer most. The roof takes the full force of the sun, and warm air rises from the floors below, which is why a loft bedroom can still be warm at bedtime.
These are the situations we see most often:
- An old system that needs replacing
- A room that’s unbearable on warm days
- Uncertainty over the right type and size of system
Around St Paul's, a quick check of the listing and conservation maps is part of planning any install.
What to look for in a quote
- Whether the price is fixed or an estimate
- Which VAT rate the quote uses, and why
- Which brand and model they’re proposing, and why
Why deal with it now?
For homeowners, timing can matter for VAT: HMRC zero-rates the installation of energy-saving materials in homes until 31 March 2027, after which the rate becomes 5%. Whether a particular system qualifies depends on the facts, so we confirm the VAT on your quote. This is general information, not tax advice. Consents in London blocks can take time, which is another reason to plan the job in Hook early.
One room or a whole building, we price it on the same basis: what needs doing, how we get to it and what it needs. You’ll have a fixed price before any work starts, with VAT shown clearly.

Safe owner checks
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone us on 07833 053749 or fill in the contact form.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Homes in Hook and air conditioning
About 43% of homes in and around Hook were built between the wars, according to the Valuation Office Agency’s council tax figures. We check the wall construction on homes of that age, as it decides how the pipework goes through. London installs often hinge on outside space, the lease and access to the building.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
