Owning your own home

Ashp grants have gone up - are they worth it yet?

If you've got a cold, draughty house they don't really work. You'll need a lot of remedial work done before they become a good bet.

They work well in places that are

• well sealed
  
• large heating surfaces, i.e. wet underfloor heating
  
• well insulated to retain heat
  
  

or

• you can't get gas for whatever reason to replace an oil fired boiler
