  • The close

Dear Ms Ashworth,

The hook

Kensington Grove Housing Association's commitment to affordable homes for local families is something I genuinely admire, and it is a big part of why I am applying to be the Administrative Assistant in your Finance team. I enjoy work that helps an organisation run well, and I would value doing that for a housing provider whose purpose I believe in.

Why it worksIt links the candidate's motivation to the association's purpose, which matters in the social housing sector.
The proof

For the past three years I have been Receptionist and Administrator at Thameside Dental Group, a busy practice with 14 clinicians. I process around 60 invoices a week and reconcile petty cash with no discrepancies at audit. I also digitised our patient filing, freeing up a full storeroom and cutting retrieval times considerably. Patients regularly mention the welcome they receive, and our feedback scores rose to 4.8 out of 5.

Why it worksInvoice volume, audit results and feedback scores prove accuracy and service quality.
The fit

Your advert mentions accuracy, data entry and supporting colleagues across departments. I am confident with Excel, including lookups and pivot tables, and I have used Sage for purchase ledger work. I handle personal data carefully under GDPR and keep calm when several requests arrive at once. I would bring a friendly, reliable approach to your finance team and the tenants it ultimately serves.

Why it worksIt mirrors the advert's requirements and names Excel, Sage and GDPR, skills UK employers screen for.
The close

I would be pleased to discuss my application further and am available for interview at your convenience, including at short notice. I can also provide references from the practice manager and senior partner at Thameside Dental Group. Thank you for taking the time to consider my application.

Why it worksA polite, traditional close fits a UK letter addressed to a named manager.

Yours sincerely,
Gavin Powell
