Gas Boiler Installation Reading

For a typical 3-bed Victorian terrace in Caversham with one bathroom, a 28-30kW combi boiler is usually ideal. It eliminates the old hot water cylinder and loft tank, freeing up space. If the property has been converted into flats or has two bathrooms, a system boiler with an unvented cylinder may be better. We assess the property during a free survey and recommend the right setup for your specific home.

We remove the back boiler unit from behind the gas fire, cap the old chimney flue, and decommission the fireplace opening (or restore it for decorative use). The new condensing boiler is typically wall-mounted in the kitchen with a balanced flue through the external wall. We also replace the old gravity-fed cylinder with either instant hot water from a combi boiler or a pressurised unvented cylinder. The whole job usually takes 2 days.

Without protection, yes. Reading's water is over 300mg/l calcium carbonate, which causes rapid limescale buildup in boiler heat exchangers. We fit an in-line scale reducer on every installation as standard. For the best protection, especially in RG4 and RG1 postcodes where hardness is highest, we recommend adding a water softener. This keeps the heat exchanger clean and maintains the boiler's efficiency and warranty.

Yes, we regularly install boilers in Reading's Flood Zone 2 and 3 properties along the Thames and Kennet. We mount the boiler above anticipated flood levels (minimum 1.2m from floor), use IP-rated electrical connections, route condensate internally, and fit non-return valves on drainage. These precautions protect the boiler if flooding occurs.

Absolutely. We cover all Reading postcodes including RG5 (Woodley), RG6 (Earley and Lower Earley), RG2 (Whitley and Shinfield), RG4 (Caversham), and RG30/RG31 (Tilehurst). We also serve Winnersh, Wokingham, and surrounding areas. There is no additional call-out charge for any Reading postcode.

Yes, this is one of our most common installations in the Lower Earley and Woodley estates. We remove the old boiler, cold water tank from the loft, and hot water cylinder from the airing cupboard, then fit a combi boiler (usually in the kitchen) with new pipework to all radiators. You get instant mains-pressure hot water and free up the cupboard and loft space. The conversion typically takes 1-2 days.

Yes. We install boilers in rental properties and HMOs across Reading, including the high-demand university area. We ensure the installation meets landlord gas safety regulations, fit CO detectors as required, and provide the CP12 Gas Safety Certificate you need for tenancy compliance. We can also set up annual service reminders to keep your certificate current.

A combi boiler replacement in a 3-bed semi typically costs between £2,200 and £3,500 depending on the brand and any additional work needed. A full system conversion from a back boiler or gravity-fed system costs £2,800 to £4,500 as it involves more pipework. We provide a fixed-price quote after a free survey — no hidden costs.
