How much must I spend to get my rental to EPC C, and when can I claim an exemption?
Rented homes need the equivalent of EPC Band C by 1 October 2030, with a £10,000 limit on what a landlord must spend.

Enter your band, your quotes and what you have already spent, and see what is left of the limit and what an exemption file needs.

Only matters under £100,000, where the limit is 10% of value.
Eligible improvements funded from October 2025 count toward the limit.

The plan leaves spending headroom and may not reach Band C
Your quotes total £1,200 and £8,800 of the limit is unspent. An exemption is only available once the limit has been spent, so ask your assessor which further measures to add.

Where it sits
A planning aid, not advice. The deadline, the £10,000 limit, the lower limit for homes under £100,000, the 10-year exemption and the £30,000 penalty are from the government's response to its consultation, read on 7 October 2026. The detailed regulations and the register's evidence rules were not in the sources read, so the evidence file is a sensible record, not the register's own form.
LetBuddy holds each property's certificates with their expiry dates, so the EPC before and after the work, the invoices and the dates sit with the property, ready for whoever asks.
Common questions
When must a rental property reach EPC C?
The government's response sets a single deadline of 1 October 2030 for all tenancies in England and Wales. The standard is the equivalent of Band C, measured with new metrics (fabric performance, plus heating efficiency or smart readiness), so a certificate issued under the old system is a guide rather than the final test.
What is the £10,000 cost cap?
The most a landlord is required to spend per property on eligible improvements. Eligible work funded from October 2025 counts toward it. Homes valued below £100,000 have a lower limit of 10% of the value.
What happens if £10,000 does not get me to Band C?
Once the limit has been spent and the home still does not meet the standard, you can register an exemption valid for 10 years and carry on letting. Keep the invoices, proof of payment and before and after certificates; the register will want evidence of the spend.
Do grants and VAT count toward the cap?
The summaries this tool is built from do not say, so it does not assume either way. Check the current register guidance before you rely on a figure that depends on it.
What is the penalty for missing the standard?
Up to £30,000 per property, per breach, under the changes announced in the government's response.
Does the tool tell me which band my works will reach?
No. How far a measure moves the rating depends on the home, and only an assessor's recommendation report can say. Enter the band they give you and the tool tells you whether the plan fits under the limit.
Is anything I type stored?
No. It runs in your browser and nothing is sent anywhere. Copy or download the evidence file to keep it.
