Boiler Installation FAQs - Horsham

How much does a new boiler installation cost?

Our boiler installations start from £1,700 +VAT for the Silver package, which includes a new entry-level A-rated boiler, professional Gas Safe installation, removal of your old boiler, and a manufacturer warranty. Our most popular Gold package starts from £2,150 +VAT and includes a system cleanse, premium magnetic filter, and smart thermostat. All our installations begin with a quick guide price, followed by a free home survey to provide a Guaranteed Fixed Price. No hidden costs - the price we quote is the price you pay.

How long does a boiler installation take?

A straightforward like-for-like boiler swap typically takes one day - usually between 4 to 6 hours. If we need to move the boiler to a new location or make significant pipework changes, it may take 1 to 2 days. We'll confirm the expected timescale when we provide your quote.

Are your engineers Gas Safe registered?

Yes, absolutely. Every Platinum Boilers engineer is Gas Safe registered, fully qualified, and regularly assessed to ensure they meet the highest industry standards. You can verify our registration at any time through the Gas Safe Register. Your safety is our top priority.

Can you help me choose the right boiler?

Of course. Our engineers will assess your property - including the number of bedrooms, bathrooms, and your hot water usage patterns - and recommend the most suitable boiler. We'll explain the options clearly and give you all the information you need to make the right decision. There's never any pressure to buy.

Common Questions from Horsham Homeowners

Do larger Horsham homes need a different type of boiler?

Often, yes. Many detached and semi-detached properties across RH12 and RH13 have multiple bathrooms and higher hot water demands. In these cases, we typically recommend a system boiler paired with an unvented hot water cylinder, which delivers strong water pressure to every tap and shower simultaneously.

Do you cover rural properties outside Horsham town?

We cover the whole Horsham district including Southwater, Warnham, Rusper, and Billingshurst. Rural properties sometimes have unique requirements such as longer flue runs or oil-to-gas conversions, and our engineers are experienced with the full range of installations.
