Servicing and safety checks

New boilers and heating
Combi, system and regular boiler replacements, radiators, power flushes and magnetic filters.
Gas work is not a DIY job. By law, anyone working on your boiler, gas fire or hob must be on the Gas Safe Register. Before they start, ask to see their Gas Safe ID card and check the back to confirm they're qualified for your type of appliance.
In the Victorian streets of Upton and Chalvey, and in many inter-war homes, regular boilers with a hot water cylinder and loft tanks are still common. A switch to a combi or a system boiler is worth discussing when the boiler is replaced. In post-war homes in areas such as Britwell, Wexham and Langley, many systems are on their second or third boiler but still have their original radiators and pipework. Old systems collect sludge, which can damage a new boiler unless the system is flushed.
Many Slough homes have been extended, or now have more bathrooms than they were built with. A combi suits homes with one bathroom best. With two or more bathrooms used at once, a system boiler with an unvented cylinder may suit you better, so ask each engineer to explain their recommendation. In flats, the boiler is often in a kitchen cupboard, and where the flue goes matters, so check that a new boiler can be fitted in the same place before you agree a design.
Water across Slough is hard, and limescale builds up fastest where water is heated. In a combi, that means the plate heat exchanger that makes your hot water. Signs include hot water that swings between hot and cold, a boiler that bangs, and flow that drops over time. Check every new-boiler quote includes scale protection, a magnetic system filter and inhibitor.
Slough has a lot of rented homes. Every rented home with gas needs a landlord gas safety check every 12 months, and a carbon monoxide alarm in any room with a fixed fuel-burning appliance, such as a gas boiler or gas fire. When comparing quotes, check the boiler make and model, the warranty and what keeps it valid, and whether the system will be flushed. Reviews on Trade Pilot come from real, invoiced jobs. If you smell gas, leave the property, turn off the gas at the meter if it's safe to do so, and call 0800 111 999.

Frequently Asked Questions
Usually £80 to £150. Most boiler warranties need a service every year, so check yours and keep the records.
A like-for-like combi swap usually costs £2,200 to £4,000 fitted. Converting a regular or system boiler to a combi, or moving the boiler, costs more because of the extra pipework and flue work.
Not always. A combi suits one bathroom and modest hot water use. With two or more bathrooms used at once, a system boiler with an unvented cylinder may suit you better.
It can. Limescale builds up in the part of a combi that heats your hot water, and can cut performance and shorten its life. A scale reducer, a magnetic filter and an annual service all help.
A gas safety check every 12 months by a Gas Safe registered engineer, with a copy for tenants, and a carbon monoxide alarm in any room with a fixed fuel-burning appliance, such as a gas boiler or gas fire.
