Done-for-you letters

Branded letters, printed and posted for you

Upload your logo and letterhead once, or let PlanPost generate one for you. Every matched application triggers a letter personalised with the homeowner's address and the project they applied for. The greeting stays “Dear Homeowner”: we never use their name. Royal Mail, same working day.

“The letters look better than anything I'd have put together myself. One landed on a £72k loft before the homeowner had even spoken to another builder.”

Re: Your planning application at 22 Laurel Gardens

Dear Homeowner,

Congratulations on submitting your planning application for a loft conversion at 22 Laurel Gardens. It's exciting to see local homeowners investing in improving their properties.

I'm writing to introduce Oakwood Construction, a local building company that specialises in extensions, loft conversions and home improvements across South Sheffield. We've been trading since 2012, and everything we build is carried out by our own team rather than subcontractors, so someone is on your job every day and the work never stalls.

We finished a loft conversion much like yours on Abbeydale Road earlier this year: two bedrooms and a shower room, done in eleven weeks with the family living at home throughout.

I know the two big questions at this stage are what it will really cost and what it's like to live through the build. Those are exactly the things I'd rather set out honestly with you before you commit to anything.

If you'd like to discuss your plans or would welcome a free, no-obligation consultation, I'd be happy to visit at a time that suits you. Call me on 0114 555 0192, or scan the code below to see examples of our recent work.

I look forward to hearing from you.

Kind regards,

Dave Morgan
