Pricing FAQs
Our standard visit fee of £75 + VAT covers travel to your property, a full investigation and diagnostic assessment, and leak tracing where required. Once we have identified the issue, we will provide a fixed written quotation on site before any work begins.
We will present you with a clear, fixed price quotation for the repair or installation required. There is no obligation to proceed — if you choose not to go ahead, you simply pay the visit fee. If you do proceed and the work is completed during the same visit without the need for ordered or specialist materials, the visit fee is deducted from your final invoice. Where works require a return visit or parts to be sourced, a fixed written quotation is provided.
Yes — for larger jobs or issues you already have a good understanding of, you can send us details, photos, or short videos via WhatsApp or email. We will review and come back to you with a fixed written quotation, so you know the full cost before we attend.
Parts and materials are quoted separately and itemised clearly within your fixed quotation. We'll always confirm costs with you before sourcing anything, so there are no surprises on completion.
All prices shown are exclusive of VAT. VAT will be added at the standard rate (currently 20%) to your final invoice.
We require payment on-site upon completion of the job. We accept bank transfer, Apple Pay/Google Pay, cash, or cheque on request.
Yes — we offer a 12-month workmanship warranty on all labour carried out by our engineers.
We provide competitive package deals for landlords, including bundled boiler servicing and gas safety certificates. Get in touch to discuss your portfolio requirements.
Our annual split system service covers a full clean of the indoor unit filters, inspection of the indoor and outdoor coils, checks on refrigerant pressure and operation, electrical connection checks, condensate drain inspection, and a full functional test of heating and cooling modes. We will advise on any remedial work required and provide a fixed quotation before proceeding.
We recommend an annual service for all split system air conditioning units. Regular servicing maintains efficiency, extends the lifespan of the equipment, and is often required to keep manufacturer warranties valid. Neglecting servicing can result in reduced performance, higher running costs, and more costly repairs down the line.
Yes — our pricing is per split system, which includes both the indoor (evaporator) unit and its paired outdoor (condenser) unit. A property with two separate indoor units connected to two separate outdoor units would be classed as two systems.
Yes. Multi-split systems — where two or more indoor units are connected to a single outdoor unit — are priced on a case-by-case basis. Please contact us with the make, model, and number of indoor units and we will provide a competitive fixed quotation.
Our out-of-hours emergency visit fee is £125 + VAT, covering attendance between 6pm and 8am, weekends, and bank holidays. The same principle applies — a fixed quotation is provided on site, with the visit fee deducted from the total where work is completed during the same visit without the need for ordered or specialist materials.
