Question 1

What happens during a central heating system check?

Accepted Answer

We assess your radiators, valves, pipework and existing filter to find exactly where heat is being lost before recommending anything. Once we know what the system needs, we give you a fixed quote, so you know the full cost before any work begins.

Question 2

Are you Gas Safe registered?

Accepted Answer

Yes. Spencer Jordan Plumbing and Heating is Gas Safe registered, Register No. 640113, which you can verify directly on the Gas Safe Register. We only carry out central heating and gas work within that registration.

Question 3

Why are my radiators cold at the bottom but hot at the top?

Accepted Answer

This usually means sludge or debris has settled at the bottom of the radiator, restricting water flow. A powerflush is typically the right fix rather than repeatedly bleeding it, which will not clear a sludge build-up.

Question 4

What does balancing a central heating system involve?

Accepted Answer

Balancing means adjusting the flow to each radiator so heat is distributed evenly, room by room, instead of the nearest radiators taking most of the heat. We usually balance the system alongside fitting or adjusting TRVs once it has been cleaned.

Question 5

What should I do if I smell gas in my home?

Accepted Answer

If you smell gas or suspect a leak, you should immediately open doors and windows to ventilate the area, turn off the gas supply at the meter (if safe to do so), avoid using any electrical switches, naked flames, or phones inside the property, leave the property, and call the National Gas Emergency Service on 0800 111 999 immediately. Once the emergency has been handled, contact us during working hours for any follow-up repair work.

Question 6

Do you cover central heating repairs across Sherfin?

Accepted Answer

Yes. Spencer Jordan Plumbing and Heating covers central heating installation, repair and maintenance across Sherfin and the wider Lancashire area. We work Monday to Friday, 8:30am to 5:00pm, and prioritise urgent heating problems during working hours.

Question 7

Do you give a fixed price before starting work in Sherfin?

Accepted Answer

Yes. Every central heating job is quoted as a fixed price once we have assessed your Sherfin property, so you know the full cost before anything begins. There is no obligation to book after the quote.

Question 8

What is a powerflush and do I need one?

Accepted Answer

A powerflush forces cleaning fluid through your heating system at high velocity to remove built-up sludge, rust and debris. If radiators run cold in patches, or the boiler makes banging or kettling noises, it is often the recommended first step before any other work.

Question 9

Do I always need a new boiler if some rooms stay cold?

Accepted Answer

No. Cold rooms and uneven radiators are often a central heating problem, not a boiler fault, and a powerflush, a new magnetic filter or some balancing is frequently a far cheaper fix. We always recommend the proportionate solution first.

Question 10

How often should I have my boiler serviced?

Accepted Answer

We strongly recommend having your boiler serviced annually by a Gas Safe registered engineer. Regular servicing ensures your boiler operates safely and efficiently, helps prevent unexpected breakdowns, keeps your manufacturer's warranty valid, and can extend the lifespan of your boiler by several years. An annual service typically takes around 30-45 minutes and includes safety checks, efficiency testing and a visual inspection of key components.
