New boilers and heating

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 Henley's listed buildings and conservation areas, the hardest part of a boiler job is often where the flue goes. A new flue on a front wall, through an old timber frame, or into a chimney may need consent, so check with South Oxfordshire District Council before you agree a design. Ask each engineer where they'd put the flue and the condensate pipe.
Many of Henley's period homes have big rooms, solid walls and old windows, so they lose heat quickly. A good engineer will size the boiler and radiators to the house and how you use hot water, rather than simply matching the old boiler. Larger homes with two or more bathrooms often suit a system boiler with an unvented cylinder better than a combi. In later homes, many systems are on their second or third boiler with the original radiators and pipework, where sludge can damage a new boiler unless the system is flushed.
In the villages around Henley, some homes aren't on mains gas. LPG appliances need a Gas Safe registered engineer qualified for LPG, so check the back of their ID card. Oil boilers are a different trade: they need a technician registered with OFTEC, so say which fuel you have when you post your job.
Thames Water supplies Henley, and the water is hard. Limescale builds up fastest where water is heated. In a combi, that means the plate heat exchanger that makes your hot water. Check every new-boiler quote includes scale protection, a magnetic system filter and inhibitor. If you live near the river, keeping the boiler and controls above likely flood levels can save a lot of trouble.
Every rented home with gas needs a landlord gas safety check every 12 months. 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.
Usually, yes, but where the flue and pipework go matters. A flue on a front wall, through an old timber frame or into a chimney may need listed building consent, so check with the council before you agree a design.
For LPG, yes, if the engineer is Gas Safe registered and qualified for LPG; check the back of their ID card. For an oil boiler, you need a technician registered with OFTEC instead.
Ask to see their Gas Safe ID card and check the back, which lists the types of gas work they're qualified to do. You can also check them on the Gas Safe Register website.
