Air Conditioning Installation in Brighton & Hove

Bishops Plumbers manages the job as main contractor — survey, design, electrical supply, condensate drainage, builders work and aftercare. The refrigeration side of the installation is carried out by our REFCOM-registered installation partner, whose engineers hold current F-Gas certification.

UK law requires that anyone working on refrigerant circuits holds this certification, and we’re straightforward about how the work is split. You have one contract, one quote and one number to call.

Air conditioning systems contain fluorinated refrigerant gases. These are potent greenhouse gases, so UK law restricts who may install, service or decommission the equipment that contains them. Companies must hold certification from a body such as REFCOM, and individual engineers must hold Category I–IV certificates.

If you’re getting quotes from more than one company, ask each of them for their company certification number and confirmation that the engineers attending hold current personal certificates. Anyone doing this properly will give you both without hesitation.

Modern inverter-driven units are far more efficient than older fixed-speed systems — they ramp up to reach the target temperature, then throttle back to maintain it rather than cycling on and off. Running cost depends on the size of the room, how well insulated it is, the efficiency rating of the unit and how long you run it for.

In heating mode, an air conditioning system moves heat rather than generating it, which is why it can work out cheaper to run than an electric heater for the same room. We’ll give you realistic figures for your specific setup at survey stage.

Please note that air conditioning is not eligible for the Boiler Upgrade Scheme or other government heat pump grants — those apply to full air source and ground source heat pump systems installed by MCS-certified installers.

Indoor units on modern systems are quiet enough for bedrooms and living rooms, and most have a silent or night mode that runs the fan at its lowest speed. The outdoor condenser makes more noise, so siting matters — we’ll look at where it can go with the least impact on you and on neighbouring properties, including anti-vibration mounts where appropriate.

It depends on the property and where the unit goes. Restrictions are tighter on flats, listed buildings and properties in conservation areas — and Brighton & Hove has a large number of conservation areas, so it’s a genuine consideration here rather than a formality.

We’ll flag anything likely to need consent at survey stage, and we’d always recommend confirming with Brighton & Hove City Council’s planning department before work is booked in.

Yes. Almost all the systems we install are reversible, meaning the same unit provides heating in winter and cooling in summer. It won’t replace a whole-house central heating system, but for a specific room — a converted loft, a home office, an extension, a conservatory — it’s often a more practical and more efficient answer than extending the heating system.

A single wall-mounted system in a straightforward location is usually a one-day job. Multi-split systems, longer pipe runs, or installations needing scaffolding or core drilling through difficult walls will take longer. We’ll confirm the timescale in writing when we quote, so there are no surprises.

Filters should be cleaned or replaced every few months — a simple job you can do yourself, and we’ll show you how at handover. Beyond that, an annual service is recommended to check refrigerant levels, clean the coils and inspect the electrical components. The refrigerant checks must be carried out by an F-Gas certified engineer, which we arrange through our installation partner.

If your system contains 5 tonnes CO2 equivalent of refrigerant or more, you have a legal duty as the operator to have it leak-checked at set intervals and to keep records. This mainly affects commercial systems — we’ll tell you clearly if it applies to you.

With regular servicing, 10 to 15 years is a realistic expectation, and often longer. Neglected systems fail earlier — a blocked filter or a dirty coil forces the unit to work harder, drives up running costs and shortens its life.

Yes. The dedicated supply, isolator and containment for your air conditioning system are handled as part of the installation, so you don’t need to arrange a separate electrician. All electrical work is completed to current wiring regulations and certified on completion.
