Having to get your boiler fixed or replaced out of the blue isn’t something we would wish on anyone. It’s a hassle, it’s frustrating, and many families might not have the funds to fork out that much money. That’s why the Government and certain energy companies have recently implemented boiler grants for people those that aren’t able to put aside a couple thousand pounds.

What’s in This Guide to Boiler Grants?


What Kind of Heating Systems Does Grant Manufacture?

Grant offers the following boiler options:

  1. Biomass – a wood-fuelled system that offers a renewable alternative to fossil fuels, such as gas or oil.
  2. Combi – Grant’s oil boilers are compact in size and ideal for smaller properties, particularly those with little to no roof space.
  3. Condensing – the company’s condensing wood pellet-fuelled boiler provides optimal energy conversion, delivering heat throughout the home.
  4. Conventional – these oil boilers are ideal for properties with two or more bathrooms and/or low water pressure (and for whenever household members want to use lots of hot water at once). Conventional boilers are Solar Water Heating-compatible, too.
  5. Hybrid – an oil/air-source heat pump system that combines blue-flame oil-heating efficiency with renewable Aerona³ air-to-water technology.

How do I choose one?

Grant boilers are available with optional (one-year or three-year) extended warranties. Here is how the top models compare:

  • Grant produces six VortexBlue (Internal) conventional boiler models, which are all endorsed by the EST.
  • and the External and Combi models are Which? Best Buys.
  • VortexBlue (External) and VortexBlue (Internal) combi boilers are each available as three model options.
  • The Spira, Vecta and VortexAir models are endorsed by the Microgeneration Certification Scheme (MCS) for its implementation of sustainable energy technology.
  • The Spira comes in nine varieties, and the condensing Spira boiler is approved by the Heating Equipment Testing and Approval Scheme (HETAS).
  • The Vecta (Internal) and Vecta (External) are each available as a single model.
  • The VortexAir comes in four selectable options (two oil-only models and two hybrid models), and allows for two-stage installation (i.e. the oil boiler component can be fitted first to ensure that heat is quickly available for a property).

Spira, Vecta and VortexAir heating systems are more expensive than the average boiler. However, operating one of these boilers allows homeowners to apply for the Renewable Heat Incentive (RHI).

This government-backed initiative typically rewards the installation of renewable heating technology with quarterly cash payments over a 7-year period. For more information, visit the EST’s Renewable Heat Incentive page.

Installation Costs

The cost of installing a Biomass boiler, i.e. the Vecta (Internal or External), is included in the price in the table above. You can expect to pay between £2,000 and £2,600 to have a combi boiler installed.

The combined cost of purchase and installation for the Spira, Grant’s condensing wood pellet boiler, is noted in the table above. A conventional boiler costs, on average, a little under £2,000 to fit. Installing a hybrid heating system (i.e. the VortexAir) could set you back anywhere between £13,000 and £20,000.

The cost of installation is dependent on a number of factors, including the size of the property and the number of rooms, the size of the boiler, and whether it’s a fresh installation, relocation or replacement.

What Are My Payment Options?

Before you decide which boiler is best for your home, be sure to get three independent quotes in order to secure the best possible deal. We advise the same in terms of installation (assuming the cost of the boiler and its installation are not included in the same price).

When you choose your boiler, bear in mind that selecting the cheapest option isn’t necessarily going to save you money in the long term. Paying a little more for reliability and all-round quality will almost certainly guarantee that you will encounter fewer issues – plus your repair bills should be smaller, too.

Oil-fuelled boilers for the home are not as widespread as their gas and electricity equivalents – hence why none of the major energy companies currently supply them – and wood pellet and hybrid boilers are even less common.

It’s not possible to buy directly from Grant, so when you have selected your ideal boiler, you’ll require the services of a boiler replacement company.

In your area, you should have access to a number of experts who will be able to provide a range of options, and possibly even 0% financing.
