Something specific in mind? We fit other models where the job calls for it — ask at the survey.

Hot water cylinders

Strong hot water for busy homes.

Two-plus bathrooms in regular use? A system boiler with an unvented cylinder gives everyone mains-pressure showers at once — no combi juggling. We fit and service the established cylinder names — Megaflo, Joule, Gledhill and Telford — sized to how your household actually uses hot water, with the safety discharge and controls done exactly to spec (it's G3-regulated work, and we're qualified for it).

Cylinders are priced at the free survey — the right size and model depend on your mains flow and airing-cupboard space, so we measure first and put the price in writing.

Why this kit

Every brand here, chosen on purpose.

We fit ranges our engineers know deeply — not a fifty-boiler catalogue. Here's the thinking, plainly.

Boilers

Boilers — the right brand for the job

Worcester Bosch, Vaillant and Baxi — ranges our engineers fit week in, week out, so every install goes in to the manufacturer's spec and is registered properly, which is what keeps the warranty valid. Sometimes the premium boiler is the right call; sometimes the value one is — we tell you which, and why, at the survey. And because we're local, the person who fitted it is the person who services it.

Air conditioning

Air conditioning — Daikin first, and the rest of the best

Daikin leads our AC work, alongside Mitsubishi Electric, Samsung, LG and Fujitsu — all run whisper-quiet on normal settings, and one system does both seasons: cooling in July, efficient heating in January. Design unit, draught-free unit or the value pick — sized to your room rather than the invoice, and fitted by F-Gas certified engineers, as the law requires.

The range, plainly

Which brands do you fit?

Boilers: Worcester Bosch, Vaillant and Baxi. Air conditioning: Daikin, Mitsubishi Electric, Samsung, LG and Fujitsu. We fit ranges our engineers know deeply rather than a fifty-boiler catalogue — and we recommend by what suits your home and budget, including when the cheaper option is the right one. If a job genuinely calls for something else, we'll say so at the free survey.

Is the 'fitted from' price really the price?

The fitted-from figures are honest guide prices for a typical installation — materials, labour, a full system flush, certification and VAT all included. Your exact price is confirmed at the free survey and put in writing — and once it's in writing it doesn't change. No day-rate surprises, ever.

What warranty do I get?

The manufacturer's warranty for the model you choose — the exact years are shown on each boiler's specs and confirmed in writing on your quote. On selected Worcester Bosch boilers we can extend that to up to 12 years. We register the appliance for you, and an annual service keeps the warranty valid.

Which boiler size do I need?

Roughly: 25kW suits flats and smaller homes with one bathroom, 30kW a typical three-bed family home, 35kW bigger homes with strong hot-water demand. But sizing properly depends on your water pressure and how you actually use hot water — the free survey confirms it before anything is ordered.

Does the air conditioning really heat as well?

Yes — an air-to-air system is a heat pump: the same unit that cools your bedroom in July heats it efficiently in January. For heating the one room you use most, it's often the cheapest option there is — we'll show you the honest numbers at the survey.

Not sure which one?

Answer four questions — the calculator matches the range to your home.
