Our Services

Boiler Service

Boiler Service

A Gas Safe registered engineer checks your boiler's safety and efficiency, testing the components that keep it running properly and catching small issues before they become breakdowns. An annual service is usually what keeps your manufacturer's warranty valid, so skipping it can cost you more than the service itself. Nothing extra is added to the job unless something's found, and you'll always be told first.

Landlord Gas Safety Certificate (CP12)

Landlord Gas Safety Certificate (CP12)

We inspect every gas appliance in the property and issue your CP12 certificate the same day, ready for your records or your letting agent. This certificate is a legal requirement for landlords, renewed every 12 months, so having it current protects you as well as your tenants. If anything fails the inspection, we'll explain what's needed and quote it separately before any repair work starts.

Boiler Repair

Boiler Repair

We diagnose the fault properly, explain in plain terms what's actually wrong with your boiler, and quote any parts before fitting them. Knowing the real cause before you commit to spending means you're not paying to guess. No parts are fitted and no further work is done until you've agreed the price.

Emergency Call-Out

Emergency Call-Out

We prioritise burst pipes, major leaks and no-heating emergencies and get an engineer to you as quickly as we can. Acting fast on a burst pipe or major leak is what limits water damage to floors, ceilings and belongings. The call-out price is the call-out price, agreed with you before the engineer sets off, with no surprise charge added on top once they're at the door.

Tap & Valve Replacement

Tap & Valve Replacement

We replace the faulty tap or isolation valve in your kitchen or bathroom and test the connection afterwards to make sure there's no drip or leak. A worn isolation valve isn't just an inconvenience, it's often what stops a small job turning into an emergency later on. We fit like-for-like wherever we can, and if the pipework needs adapting we'll tell you before doing the extra work.

Drain Unblocking

Drain Unblocking

We clear the blockage from sinks, showers or external drains using the right equipment for the job, then check the flow afterwards to confirm it's running clear. A slow or blocked drain left alone tends to back up further and can lead to overflow or damage. If the blockage turns out to be a bigger issue further down the line, we'll tell you and quote before taking it any further.

Leak Detection & Repair

Leak Detection & Repair

We trace the source of the leak, including hidden leaks behind walls or under floors, and carry out the repair in the same visit wherever the job allows. Left untraced, a hidden leak can cause damp and structural damage long before it's ever seen. If the fix turns out to need more than expected, we'll explain that and agree it with you before doing anything further.

Radiator Replacement

Radiator Replacement

We remove the old radiator, fit the new one, and rebalance the system afterwards so heat is distributed evenly across your home rather than pooling at one radiator. Skipping the rebalance is a common shortcut that leaves other rooms cold, so we don't skip it. If the existing valves or pipework need attention to make a clean fit, we'll flag it before doing any extra work.

Smart Thermostat Install

Smart Thermostat Install

We fit the thermostat, wire it in to your existing heating system, and pair it to your phone before we leave, showing you how to use it. A properly configured smart thermostat means you can control your heating away from home, so you're not paying to heat an empty house. We check compatibility with your system before the visit, so there are no surprises on the day.

Unvented Cylinder Service

Unvented Cylinder Service

We carry out the annual service required for unvented hot water cylinders, checking the safety devices and controls that keep the system operating within safe limits. This check is carried out by a G3-qualified engineer, as it should be for any unvented cylinder. We only do what the service requires, nothing added on unless something needs your attention.

Power Flush

Power Flush

We flush the whole central heating system under pressure to clear out the sludge, rust and debris that build up in radiators and pipework over time. Left alone, that debris causes cold spots, noisy pumps and puts unnecessary strain on your boiler. If we find a fault while we're in the system, we'll tell you and quote it separately rather than adding it to the job on the spot.

Full Boiler Installation

Full Boiler Installation

We fit a new A-rated combi boiler sized properly for your home, remove and dispose of the old unit, and commission the new one so it's running efficiently from day one. A correctly sized, properly installed boiler keeps your manufacturer's warranty valid and avoids the short-cycling that wears a boiler out early. The price is agreed before we start, so what you're quoted is what you pay.

Bathroom Installation

Bathroom Installation

This is the first day of the full refit: the old suite comes out, pipework and electrics get first-fixed, and the room is protected while the work happens around you. Getting this stage right is what stops leaks, movement and cracked tiling turning up months later. We agree the full scope with you before day one, so there's no creeping list of extras once the tools are out.
