A new combi boiler supplied and fitted typically costs £2,500 to £4,000 for a straightforward like-for-like replacement, based on current UK trade pricing. Converting from a system or conventional boiler to a combi usually pushes that to around £4,000 or more, because it involves extra pipework and removing the old cylinder, not just swapping one unit for another. That range is the honest starting point. The real number for your home depends on which boiler type you’re replac

Repair your commercial boiler if it's under 10 years old, the fault is a one-off, and the repair costs less than half of a full replacement. Replace it if it's breaking down repeatedly, running below roughly 70% efficiency, or showing a safety fault like a persistent gas smell, sooty staining, or a yellow rather than blue flame — in that last case, replace regardless of cost, because safety overrides the usual rules. That's the short version. The longer version depends on how

Being Gas Safe registered doesn't automatically mean an engineer is qualified to work on your commercial gas equipment. Gas Safe registration is split into categories, and an engineer registered only for domestic boilers isn't legally permitted to touch a commercial catering range or a large commercial heating system — even though both might carry the same "Gas Safe" logo on their van. For a Portsmouth business owner, that distinction is the real question to answer before boo

A commercial gas service in Portsmouth typically costs somewhere between £120 and £460 for a single boiler visit, based on current UK trade pricing data — though sites with several appliances, larger boilers, or catering gas equipment can push that higher. There isn't one fixed national price because the figure depends almost entirely on how much equipment is actually on site, which is also why most commercial gas engineers, including us, won't quote a flat number without see

For a straightforward single-fixture blockage — a sink, bath, shower or toilet — a fair UK price is somewhere between £50 and £150, usually including the call-out and up to an hour's work with drain rods. Jetting, CCTV surveys, or a blockage on the main drain rather than a single fixture cost more, typically £100–£300, and an emergency out-of-hours visit adds a premium on top of whichever of those applies. Properties in the South East, including Portsmouth, tend to sit toward

The quickest way to unblock most household drains is boiling water with a squeeze of washing-up liquid poured down in stages, followed by a proper plunger if that doesn't clear it — both take under ten minutes and deal with the two most common causes: grease and soap-fat build-up. If neither works after two attempts, you're likely dealing with something further down the pipe than a plunger or kettle can reach, and it's time to move on to mechanical clearance rather than repea

Low water pressure is a common plumbing problem that can affect showers, taps, boilers and everyday household activities.
