Cost of installing heat pumps?

Engineer installing a heat pump unit for a rental property while considering installation costs and tax implications.

Hi everyone, I’m looking to install a heat pump for one of my lets, and if I have this right, I cannot claim the costs as day-to-day running costs?

Even though the gas boiler is all but dead, I have been told it would not pass another gas inspection due this summer.

Also, have I got it right that I cannot claim it as a capital cost when I sell the property?

Can anyone who knows about taxes and things comment?

After all, I thought this was what the government wanted us to do?

Thanks,

Sally

Editor’s note: In most cases, replacing a gas boiler with a heat pump is treated as a capital improvement rather than a repair, so the cost is generally not deductible against rental income as a day-to-day expense. However, it should normally be added to the property’s capital gains tax base cost and may therefore help reduce any CGT liability when the property is eventually sold. As always, tax treatment depends on the specific facts, and landlords should seek professional advice where significant sums are involved.

    on what basis does the editor state that it should be treated as a capital expense. it could be argued both ways in my opinion. reasoned opinions in this matter would be appreciated as this will come up more and more

    I agree. Surely one is replacing one method of heating with another of similar scope.
    Replacing single-glazed windows with double-glazing, although technically a capital improvement, has been allowed as ‘repairs’ for years.
