VAT Reclaim journey

[Benpointer]

I know there have been a few of these but I thought I would add our VAT reclaim journey to the mix.

 

We moved in on 23rd February 2026.   We received our BC completion certificate yesterday (18th june) following a painless final inspection.

 

I reviewed our spreadsheet of project VAT invoices today:  

• By comparing it with the spend spreadsheet I'd kept to manage the budget, I found an additional £1800 of VAT I could reclaim - not sure how I missed those before.
• Some of the paper invoice copies I had, proved to be no such thing - rather, sales orders or pro-forma invoices.  A few calls and emails managed to secure real VAT invoices.
• 161 invoices in total, totallying £20.9k VAT to claim
• Plenty of company names on invoices didn't match the official HMRC company names for specific VAT registration numbers.  For instance: Screwfix is really Kingfisher and Toolstation is really Travis Perkins (with the same VAT reg no.).  I am not sure how much of an issue that is but I corrected them anyway.
• We had maintained a spreadsheet in the HMRC template format so populating their template was a simple cut and paste.

 

I used the online HRMC form to submit the claim, guided by Google Gemini.  I know AI gets a bad rap but I really like Gemini.  I guess we'll see if my trust is misplaced.

 

Some points about the online submission.  There seem to be some trick questions, e.g:

• When did you occupy the property?  Gemini advises making sure it ties in with what the Council know because HMRC can check (really?)  But in our case that means three invoices since 23rd February could be discounted. I changed the spreadsheet description for these entries to make it clear we had to do this work to pass BC.  We'll see whether HMRC allow those.
• How many kitchens or utility rooms do you have?  In our case 1 of each.  Gemini advise entering 1 kitchen, 1 utility room but you can only put in a number, so I entered 1 (as in 1 kitchen or 1 utility room.  The risk in entering a number >1 is that HMRC assume it's a multi-residency project and will reject.

 

I received an email confirmation of my submission straight away, will keep you posted on progress or issues.

This looks like really good advice for someone like me who is at the start of their self-build. 

Sorry to be a pain, but I have googled and read a lot of HMRC's pages and I can't find this anywhere. Do you have a link to the template please?

Can I ask what this is as a rough percentage of total spend?  I've put VAT reclaim into my figures at 5% of the total cost. I know it's 20% but I've reckoned on being able to claim back on around a quarter of expenditure. Does this seem about right?

Hi Square Feet,

 

Here's an empty copy of the spreadsheet I created.  

 

VAT invoices template.xlsx

 

It's based on the format of Table A from the reclaim form https://assets.publishing.service.gov.uk/media/65858474fc07f300128d46e8/VAT431NB.pdf

 

The total VAT we're reclaiming is quite a small %age of our total spend because most of the spend was on zero-rated build and install work where the contractors supplied the materials. The big ticket items of groundworks, timber fram, windows, zinc roof, solar PV and electrics, were all in this category.  

 

Our main materials spend items were timber cladding, floor tiles, kitchen units, doors, lighting, insulation, plus lots of timber and fixings.   

 

How much you will be claiming back depends on how much you put through contractors and how much materials you buy yourself.

 

Hope that helps.

@Benpointer Nice one thanks for the spreasheet info. 

Yes, I've read the whole of the VAT reclaim thread but was just wondering if my 'back of an envelope' figure was roughly within range. I get that it's oranges and apples though. 

Cheers

Depending on the amount you buy direct, 5% of total cost sounds reasonable to me. 👍

Mine is/will be about 10% (or second hand Aston Martin sized) 🤣

Ours too, but as suggested above depends how you buy. We have sourced the majority of things.
