Overview

What Gas Appliances Do We Install?

Connecting any gas appliance — hob, cooker, fire, range, water heater or barbecue — to a domestic gas supply is regulated work. By law it can only be carried out by a Gas Safe registered engineer. DPS is fully Gas Safe registered and handles every type of domestic gas appliance installation across Greater Manchester.

Common installs include: gas hob and oven swap-outs (the most popular kitchen project), freestanding gas range cookers, gas fires (open-fronted, glass-fronted, hole-in-the-wall, balanced flue), instant gas water heaters, and meter relocations or upgrades coordinated with your gas supplier.

Every installation includes the gas connection (rigid copper or approved flexible bayonet hose), a tightness test using a calibrated manometer, a pressure check, an emissions test (where applicable), and a Gas Safe certificate logged in the appliance's Benchmark.

We don't supply white goods at marked-up prices — buy your appliance wherever you get the best deal, and we'll fit it properly.

Why It Matters

Why DIY Gas Connections Are Never Worth the Risk

Connecting a gas appliance yourself or hiring an unregistered fitter is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. It carries unlimited fines and, in cases involving harm, prison sentences.

The dangers are real, not theoretical. A poorly tightened bayonet fitting can leak gas into the kitchen overnight, accumulating to explosive concentrations by morning. A wrongly sized supply pipe can starve the appliance, causing incomplete combustion and silent carbon monoxide release.

Home insurance is routinely voided when an unregistered installation is found after an incident. Buildings, contents, life — claims are denied because the policy required gas work to be carried out by a Gas Safe engineer. The 'saving' from cash-in-hand becomes catastrophic.

A proper Gas Safe installation typically costs £80–£200 depending on appliance and connection complexity. It comes with a certificate, a pressure test, an emissions check, and full legal compliance. There is no version of 'cheaper' that's worth the alternative.

What's Involved in a Compliant Gas Appliance Installation

Every gas appliance install starts with the gas supply itself. The pipe feeding the appliance must be sized correctly for the appliance's input rating (kW). A 5kW hob runs fine on a standard 15mm copper feed; a 25kW range cooker often requires a 22mm feed all the way back to the meter. Undersized supplies cause yellow flames, low burner output, and incomplete combustion.

Isolation is non-negotiable. Every gas appliance must have a dedicated, accessible isolation valve within 600mm of the appliance — usually a quarter-turn ball valve we can fit if your existing supply doesn't have one. This lets you isolate the appliance for cleaning, moving, or future replacement without calling an engineer back.

Gas hobs and cookers connect via either a rigid copper run (preferred for built-in hobs) or an approved bayonet hose (essential for freestanding cookers that need to be pulled out for cleaning). We use only Gas Safe-approved hoses with a current British Standard kitemark — never a generic flexi from a hardware store.

Gas fires fall into several categories with very different installation requirements. Open-fronted fires need a Class 1 chimney with proven adequate draw. Glass-fronted and balanced-flue fires need correctly sized flues, ventilation calculations, and hearth requirements per the manufacturer's manual. We assess all of this before quoting — there are no shortcuts.

Range cookers (Rangemaster, Falcon, Stoves Richmond, Britannia, etc.) typically need a 4–6mm² electrical supply for the oven and ignition, plus a 22mm gas feed for the higher input rating. Many older Manchester kitchens were built around 30kW non-condensing cookers and need both upgrades when a modern 70kW range goes in.

Tightness testing is the legally required final step. The whole gas installation (meter, supply, isolation valve, appliance) is pressurised to 21 mbar and monitored on a calibrated manometer for at least 2 minutes. Any pressure drop indicates a leak, which is investigated and repaired before the system is commissioned. The test is documented and the result recorded on the certificate.

Working pressure is then verified at the appliance test point under load — confirming the appliance is getting the manufacturer-specified gas pressure when running on full burn. For combustion appliances (gas fires, water heaters), we also run a flue gas analysis to confirm safe carbon monoxide and CO₂ ratios.

Finally, the install is notified through Gas Safe Register and you receive a certificate. The Benchmark log in the appliance manual is stamped, and a Gas Installation Certificate is emailed and posted. Keep this — it's required for warranty claims, home sales, and insurance verification.
