Frequently Asked Questions

How often should my boiler be serviced?

Most manufacturers recommend an annual boiler service to maintain efficiency, improve safety and keep warranties valid. In Wandsworth, boiler servicing costs around £157 on average. For landlords and property owners, gas safety checks and an annual gas safety check must be carried out by a Gas Safe Registered engineer under the Gas Safety (Installation and Use) Regulations 1998.

How long does a boiler typically last?

A modern boiler can last between 10 and 15 years with regular servicing and proper maintenance.

Should I repair or replace my boiler?

If your old boiler is over 10 years old and frequently breaking down, replacing it may be more cost-effective than continuing with repairs. In Wandsworth, boiler installation prices vary depending on the job, but they typically range from £2286 to £3603, with an average cost of £2855. The installation process usually includes removing the old boiler and fitting a new one, and it typically takes 1 to 3 days. Power flushing can add to the cost, and next-day boiler installation may be available for urgent replacements. A qualified heating engineer can advise on the best option for your home.

Final Verdict

Choosing the right boiler company isn’t just about price. Many family homes are best served by a system boiler paired with an unvented cylinder for stronger hot water performance. Experience, customer service and reliable workmanship are equally important.

Based on publicly available reviews, reputation and the range of services offered, WPJ Heating ranks as our top choice for homeowners in Wandsworth. Their experienced Gas Safe engineers, comprehensive heating services and strong customer feedback make them an excellent option for everything from annual servicing to complete boiler replacements.

A standard boiler installation normally takes one to three days. Whichever company you choose, always compare reviews, verify Gas Safe registration and request a detailed quotation before any work begins.
