Cap Check

What have you spent on your rental since October last year?

Not on the mortgage. On the boiler, the loft, the windows, the EPC assessment - anything that made the property warmer or cheaper to run.

If you cannot answer that to the pound, and produce the invoice, you are already losing allowance you are entitled to. Qualifying spend has been counting toward your £10,000 cost cap since 1 October 2025.

Source: the government's response to Improving the energy performance of privately rented homes, published on gov.uk. Applies to England and Wales.

Three questions. Nobody sees the answers but you.

They are not a quiz and there is no score. They are the three things a local authority can ask you for in 2030.

Question 1 Roughly what have you spent on energy-efficiency work since 1 October 2025?

Insulation, glazing, heating, controls, low-carbon heat, and the EPC assessment itself.

Question 2 Could you produce the invoices for it tomorrow morning?

Spend you cannot evidence cannot be counted toward the cap.

Question 3 How many properties do you let?
in England or Wales

The cap is per property, so this is what sets the size of your allowance.

Where these numbers come from

We have no customers to point at yet. So here is the legislation instead.

Four quotations, all from the government's own response to the 2025 consultation on the energy performance of privately rented homes. Read them yourself - the links go to the source, not to a summary of it.

All tenancies within scope of the regulations must be compliant with the standard by 1 October 2030. gov.uk · Improving the energy performance of privately rented homes: government response · England and Wales
Where the cost cap is £10,000 or 10% of the value of the house, whichever is lower. gov.uk · the same response · average expected spend per property, £5,400
Landlords will be able to count spend towards the cost cap on relevant energy efficiency measures that have been installed since 1 October 2025. gov.uk · the same response · this is the date the clock started
The validity length of the revised 'Cost cap' exemption … will be 10 years. gov.uk · the same response · claiming it means evidencing the spend

Read the response in full: gov.uk. Scotland runs a separate regime - proposed compliance on new tenancies from 2028 and all private rented property by the end of 2033, also with a £10,000 cap - but those are still draft regulations and the dates can move.

Straight answers

What this page is, and what it isn't.

You are being asked for an email address by a company you have probably never heard of, about a product that does not exist yet. That deserves plain answers rather than a marketing page.

  • There is no app yet. Cap Check is a tool we are deciding whether to build. If not enough landlords want it, we will not build it, and we will tell you so.
  • There is no price. Nothing has been decided, and you are not signing up to anything.
  • This is not legal or tax advice. It is published regulation, quoted with its source, plus arithmetic you can check on the back of an envelope.
  • Your answers to the three questions are stored with your email. That is the entire point of the exercise - we need to know whether the problem is real before we build for it.
  • KIH Technologies Ltd is a real company. Registered in England & Wales, number 17214671, registered with the ICO. We already run two paid apps, TradeKit and FishingTactix.
  • Ask us to delete it and we will. One email to kristan@kihtech.co.uk, no reason needed.

The record is easier to keep than to reconstruct.

Four years and change from here to the deadline. The invoices arriving between now and then are either filed as you go, or hunted down in 2029.
